Kilauea, sometimes written
Kilauea, is better known than Mauna Loa because it is more easily
visited and has almost always afforded signs of volcanic activity. The
altitude of its north bank at the Volcano House is given at 4,040 feet,
and is easily reached by good carriage roads from Hilo on the northeast
and the port of Honuapo on the southwest, being midway between these two
villages. From Hilo there is also a steam railroad for three-fourths of
the way, say twenty-five miles out of thirty-one. The ascent is gradual,
at the rate of about one hundred and thirty feet to the mile, so that
one does not realize that when standing on the brink of the caldera, he
is really on the summit of a lofty mountain.
There seems to exist data
for a belief in a very extensive prehistoric flow from near Kilauea
upon the Government road for over twenty miles southeasterly. At the
higher 'elevations, from about the twenty-fifth to the thirtieth mile
posts upon the Government road, the forest growth is wanting. The same
is true of a broad strip of country makai of the trail used by travelers
from Hilo to the volcano more than fifteen years ago. This trail, called
the "worst road in the world," in my note books of 1883 and 1886, seems
to have been located just outside of the forest, that belt which covers
most of the country between Hilo and the Volcano. It is a magnificent
growth of ohia, tree ferns, vines and other plants, answering to the
appellation of jungle. The climatal conditions are favorable to its
continuity over the whole of the region between the present forest and
Puna; and it is our belief that the absence of vegetation is due to a
large lava stream reaching from an older Kilauea to the lower limits of
Olaa. There is a belt of the original growth between the caldera and the
beginning of the scanty vegetation, from which immense trunks of the
"Hawaiian mahogany" are now being obtained for commercial purposes.
A recent trip from the
ninth mile post out of Hilo on the Volcano road to Pohoiki (Rycroft's)
confirmed these conclusions. Near the coast there is a dense growth of
the Pandanus or louhala. Higher up it is replaced by various shrubs,
especially the guava. The flow of 1840 is still conspicuous by the
sparse vegetation upon it, as sufficient time has not yet elapsed to
allow the complete disintegration of the basalt into soil and the
consequent growth of trees; bushes appear upon the older lavas adjacent.
The greater portion of this road between the flow of 1840 and the ninth
mile post is situated upon a barren tract of pahoehoe, if possible more
devoid of vegetation than the later stream, be cause Jess easily
disintegrated. I found two small areas of the original dense forest in
the midst of this barren tract. One is a mile in diameter, east of Pahoa
post office; the other is much smaller, near the eighteenth mile post.
Large ohias, tree ferns, ropy vines and various shrubs are as vigorous
in these islands as in the upper forest, while the interspaces exhibit
chiefly the pahoehoe, barren and devoid of vegetation. They are like the
outliers of sandstone isolated in a flat country, and supposed to have
once covered the whole region. The natural conclusion here is that the
forest originally covered the whole of Puna and that a powerful flow of
lava came from the barren tract east of Kilauea, burnt its way through
the forest, leaving here and there islands of jungle. The general
absence of vegetation would indicate that the date of the outflow is
comparatively modern, recent enough to have been witnessed by the
Hawaiians, and possibly preserved in legendary form.
The first known reference
to this volcano in the writings of Europeans is that given by Vancouver
in 1794. Under date of January 11th, he writes: "As we passed the
district of Opoona, (on ship board) the weather being very clear and
pleasant, we had a most excellent view of Mauna Loa's snowy summit, and
the range of lower hills that extend toward the east end of Owyhee. From
the tops of these, about the middle of the descending ridge, several
columns of smoke were seen to ascend, which Tamaahmaah and the rest of
our friends said were occasioned by the subterranean fires that
frequently broke out in violent eruptions, causing among the natives
such a multiplicity of superstitious notions as to give rise to a
religious order of persons, who perform volcanic rites, consisting of
various sacrifices of the different productions of the country, for the
purpose of appeasing the wrath of the enraged demon."
Menzies in his sketch of
the ascent of Mauna Loa refers to the "Volcano," from which smoke and
ashes proceeded, making the air thick and irritating to the eyes. This
was between Punaluu and Kapapala and his experiences were such as have
been repeated constantly ever since.
Before citing the account
of the next visit to the volcano by an European, it will be well to
state what has been learned from the native Hawaiian records, partly
historic and partly legendary.

Early Records of Activity at Kilauea
As is well known, the
first detachment of American missionaries arrived in Hawaii in 1820.
They gradually made themselves familiar with the island and discovered
the fact of the existence of the volcano of Kilauea. Because the natives
possessed no written literature, it has been generally understood that
their oral traditions transmitted from generation to generation had no
scientific value. Historians have discovered that these traditions are
of importance in determining the ancestry of the Hawaiians, and to some
extent their chronology; and therefore credence may be given to their
statements about volcanic activity. They imagined that the volcano was
inhabited by certain deities, and rep resented that there were
struggles among them and that they had the power to produce flows of
lava, both superficially and by underground passages from the crater to
the ocean. It may be said that these traditions represent the
conceptions formed by the natives of the nature of the eruptions; and
consequently the deeds performed can be recognized in one or another
phase of volcanic activity. Furthermore, the events are said to have
taken place during the reigns of particular kings and therefore make
known the date of certain definite eruptions. I have not been able to
investigate this history thoroughly, but have gleaned a few facts which
may be added to by experts.
The first information
afforded by the missionaries is contained in a journal of a tour of
exploration undertaken in 1823. Rev. William Ellis was an English
missionary who had resided for several years in the Society Islands and
had acquired a knowledge of the language of that part of the Pacific,
which is very much like the Hawaiian tongue. With Rev. Daniel Tyerman
and George Bennett, Ellis had explored some of the South Seas. The
Hawaiian authorities invited Mr. Ellis, together with two Tahitian
chiefs, to reside in Hawaii. The American Board of Commissioners of
Foreign Missions took advantage of the opportunity afforded by the
presence of these gentlemen to undertake the exploration of the island
of Hawaii, primarily for evangelistic purposes, and incidentally for the
acquisition of any knowledge of general importance. The missionaries
connected with the A. B. C. F. M. who were associated with Mr. Ellis,
were Reverends Asa Thurston, Artemas Bishop and Joseph Goodrich, and Mr.
Harwood, an intelligent mechanic. All except Mr. Ellis arrived at
Kailua, Hawaii, June 26, 1823. Before the arrival of Mr. Ellis, eight
days later, the company had discovered various signs of volcanic
structure, and attempted the ascent of Mauna Hualalai, but failed to
reach the summit, for want of supplies.

Distribution of Volcanic Ashes about Kilauea
At length the journey
around the island was commenced, and numerous references were made to
volcanic phenomena, which need not be repeated. They journeyed through
Kona and Kau till Kilauea was reached. They noted the conical hills of
volcanic ashes not far from Tairitii, near Kahuku, which we now
recognize as a part of the deposit blown out from Mokuaweoweo in
prehistoric times. After passing the South Cape they began to see the
clouds of smoke and to smell the fumes of sulphur emanating from
Kilauea. From Kapapala they diverged on a side trip to Ponahohoa, a
distance of five miles, where they saw the discharge that came from
Kilauea in the month of March. The story was that the goddess of Pele
had issued from a subterranean cavern and overflowed the lowlands of
Kapapala. The inundation was sudden and violent. One canoe had been
burnt and four others carried out to the sea. At Mahuka the deep torrent
of lava had transported a huge rock, nearly one hundred feet high, into
the water which was still visible. The ground at Ponahohoa exhibited
several chasms, some of them ten or twelve feet across, from which smoke
and steam was issuing. The vegetation had been scorched, and a
considerable heat was still emanating from the recently ejected lava.
This is the only notice we
have of the 1823 eruption from Kilauea. In Plate 26 may be seen a sketch
of its position and area, party of aa and partly of pahoehoe, occupying
a space about fifteen miles square and surrounding the small hills known
as Kearaarea. The plan is taken from the recent survey of Kapapala by E.
D. Baldwin and George F. Wright, executed under the direction of Walter
E. \Nail, Government surveyor. These small craters must have been formed
long before this eruption, otherwise their names would not have been
known. I have never seen any account of them, but they are quite
conspicuous as seen from the Kau volcano road.
After reaching Kaimu,
several miles east of Kilauea, the deputation listened to accounts of an
earthquake which had been experienced about two months earlier. The
ground after several minutes of quaking had been rent for several miles
in the direction north-by-east, and emitted a quantity of smoke, ashes
and luminous vapor, but none of the people were injured. One house was
situated directly over the chasm and the people were disturbed in their
slumbers. Probably this disturbance was connected with the general
eruption of 1823 from Kilauea.
After Kilauea had been
visited Mr. Ellis questioned the natives about its history. They
represented that it had been burning from time immemorial: it often had
boiled up and overflowed its banks in the earlier ages, inundating the
surrounding country; but for many reigns past it had kept below the
level of the surrounding plain, continually extending its surface,
increasing its depth, occasionally throwing up large rocks and red-hot
stones. These eruptions were always accompanied by dreadful earthquakes,
loud claps of thunder and quick succeeding- lightning. No great eruption
had taken place since the days of Keoua (1790), but many places near the
sea had been overflowed; the streams of lava had taken subterranean
courses to the shore.
The first incoming of
immigrants, as corroborated and dated by the historian Fornander, was in
the days of Wakea, A.D. 190, when the volcano was active. The later
immigration dates from A.D. 1090; and it was claimed that eruptions had
taken place during every reign since that date; which may be estimated
as once for every generation. The legend of Pele, detailed later,
relates clearly to an eruption from Kilauea, which must have taken place
a few years after 1175. About fourteen generations back, in the days of
Liloa, 1420, a violent eruption broke out from Keanakakoi. As this
seemed to be well known to the natives, it was probably of unusual
importance, and is referred to again later. There was also an eruption
at Kaimu in the days of Alapai, whose date proves to be from 1730 to
1754, according to Professor W. D. Alexander.
Another tradition relates
to the disturbances at Kapoho, a very interesting crater in Puna near
the eastern extremity of Hawaii, belonging to Mr. Shipman, who
entertained me in 1883, and later, to Mr. H. J. Lyman, whom I visited in
1899. Kapoho signifies the sunken in. It is the largest of all
the craters in Puna, one mile in diameter, enclosing two hills and a
pond of clear water, which is said to be quite saline. Inasmuch as Pele
is represented as coming here to engage in the game of holua, it seems
probable that Kapoho is connected with Kilauea. It was in the reign of
Keariikukii, an ancient king of Hawaii, that Kahavari, a chief from Puna,
with others, came to Kapoho to amuse themselves with sliding downhill.
Many people came to witness the game, among them Pele. She challenged
Kahavari to slide with her, and she was beaten. She asked for his
sledge, which he refused to give her. Becoming incensed, she stamped
upon the ground, whence followed an earthquake, rending the hill in
sunder; and in response to her call liquid fire made its appearance, and
pursued Kahavari. He had great difficulty in making his escape down the
hill to the sea, whence he was closely followed by fire and stones while
his family were overwhelmed. The special site of this action was the
crater Kukii, a crater of black and red lapilli half a mile
northeasterly from Lyman's.
The scoriae are pumiceous
like that on the south side of Kilauea. The time of Kahavari's
domination in Puna is placed by Kalakaua at A.D. 1340 to 1380, in the
resign of Kahoukapu.
Another eruption was
described by the natives as having been manifested about thirty-five
years earlier, say 1788. There are three hills contiguous to each other,
to the west of Kapoho, Honualula, Malama (Puulena) and Mariu (Kaliu).
These arrested the progress of an immense torrent of lava which
inundated the country to the north. This flow must have been analogous
to the later discharge from Kilauea in 1840.
One cannot resist the
impression that the earlier eruptions were comparable with what are
called the Vesuvian or explosive type of action; and Plate 27A is a
humble attempt to represent the conditions attending the discharge of
vapors, stones and ashes, when the whole adjacent region was covered
with the ejectamenta.

Eruption Of 1790
The account of the
eruption of 1790 was compiled by Rev. Sheldon Dibble in his History
of the Sandwich Islands, published at Lahainaluna in 1843. He
interviewed several of the survivors of the catastrophe, and was able by
repeated questionings to compile a satisfactory account of the events.
It was also given by Mr. Ellis in his Journal. Rev. H. R. Hitchcock puts
the date of the event at November, 1790, in the chronology of Hawaiian
happenings appended to his Dictionary: others had supposed it to be a
year earlier.
In the earlier months of
1790 violent battles had been fought between Keoua and Kamehameha in
their struggle for the supremacy, and now quite a large detachment of
warriors were on the way to Kau under the leadership of Keoua, an
immediate descendant of Taraiopu, a chief mentioned in Captain Cook's
narrative. He took the route upon the southeast side of Kilauea and was
encamped near Keanakakoi.
The natives explained the
disaster by the friendship of Pele for Kamehameha and hostility to Keoua.
Soon after sunset there were repeated earthquakes, the rising of a
column of dense black smoke followed by the most brilliant flames, and
streams of lava spouted up in fountains and immense rocks were ejected
to a great height. A volley of smaller stones thrown with great force
followed the larger ones, striking some of the soldiers, and bursting
like bomb shells, accompanied by lightning. Many of the people were
killed by the falling fragments and others were buried beneath masses of
scoriae and ashes. The natives did not dare to proceed. On the second
and third nights there were similar disturbances.
Not intimidated by this
event Keoua continued his march, separating for safety into three
companies. The advance party experienced a severe earthquake and a dense
cloud rose out of the crater accompanied by electric discharges. The
cloud excluded the light of day, but the darkness became more terrible
because of the glare of the red-hot lava below and the flashes of
lightning above. Soon afterwards there was a destructive shower,
extending for miles around, of sand and cinders. A few persons were
burned to death and others were seriously injured. All experienced a
suffocating sensation and hastened on as rapidly as possible.
The hindmost company which
was nearest to the volcano seemed to suffer the least, and hastened
forward after the eruption, congratulating themselves upon their escape.
On reaching their comrades of the second company, said to be four
hundred in number (Ellis says eighty), they were greatly surprised to
find them all dead, although they retained life-like postures. Not one
of the party survived, except a lone pig. The suddenness and totality of
the destruction reads like the story of the disaster at Martinique,
pouring down from Mont Pele; especially as Dibble adds: "A blast of
sulphurous gas, a shower of heated embers, or a volume of heated steam
would sufficiently account for this sudden death. Some of the narrators,
who saw the corpses, affirm that though in no place deeply burnt, yet
they were thoroughly scorched. On their return, after the final battle
in Kau, in about ten days time, the bodies were still entire and showed
no signs of decay except a hollowness of the eyes. They were never
buried, and one of the missionaries is reported to have seen many years
afterwards a human skull lying in the volcanic sand Keoua himself
surrendered to Taiana upon the hill of Makanao, one of the buttes in
Hilea, described in connection with the caldera of Mohokea.
It has been tacitly
assumed that the place where the soldiers were destroyed was near
Kilauea. The question arises would not the party have taken the regular
road from Puna to Kau. If so, they would have been situated about five
miles south from Kilauea. This trail is indicated upon Plate 26 by the
dotted line leading from the east border of the map to the sand dunes,
close by Koae and thence to the Halfway House. The first part of this
trail follows a fault line. It would seem not improbable that the
eruption came from some vent now concealed from view, because of the
distance from Kilauea; but if all the material indicated upon the map as
ashes and tuff came out in 1790, there could be no doubt as to its
calamitous effect upon the army, for there is an enormous deposit of
volcanic ashes, pumice, scoriae, lava bombs, stones and rocks spread
over several miles between Keanakakoi and the road from Puna to Kau. It
must be scores of feet in thickness. Were it removed; who knows how much
farther the caldera beneath extends to the south and southwest!
This deposit must have
been laid down by an eruption of the most violent type in prehistoric
times long before the passage of the troops of Keoua from Hilo to Kau in
1790. It was a truly terrific discharge, fully equal to anything ever
sent out from Vesuvius; and this enables us to affirm that Kilauea has
sometimes belonged to the explosive class of volcanoes and has not
always been the tame creature of today.
Professor J. D. Dana
explored the same region in 1887, and was fully persuaded that the
material thrown out was connected with the historic event of 1790. "The
distribution of the ejected stones, ashes and scoria all around Kilauea
seems to show that the whole bottom of the pit was in action; yet the
southern, as usual, most intensely so." The heavy compact basalts and
their large use indicate that the more deep seated rocks along the
conduit of the volcano had been torn off by the violent projectile
action. "It was an explosive eruption of Kilauea such as has not been
known in more recent times."
Professor Dana observed
three varieties of volcanic products about Kilauea that seemed to have
been ejected explosively from the crater. At the base from twenty to
twenty-five feet of yellowish brown tuff including very fine sand well
exposed to view near fissures. Above the tuff are two or three feet of
coarse conglomerate, including large stones; and on the summit twelve to
sixteen inches thickness of a brownish sponge-like scoria, analogous to
pumice, in pieces from half an inch across to two or three inches. Less
than two per cent of this scoria is solid: it is a network like thread
lace. One solid inch of the basalt glass would make a layer of scoria
sixty inches thick.
Because of its lightness
it will float in water and may be easily carried off by the wind. It is
most abundant south and west from the volcano; and may be seen near
Uwekahuna and at the Volcano House. The stones are about the Volcano
House and to the south of the caldera. Towards Keanakakoi, the ejected
stones of one and two cubic feet are common; others are larger. The
largest one seen contained one hundred cubic feet, and must weigh over
eight tons. Stones like this are conspicuous from one-eighth to one-half
a mile away from Kilauea. Some of them have been observed upon Uwekahuna.
They consist of the more solid basalts of the neighborhood, usually of a
gray color and somewhat vesicular. Some carry olivine and all appear to
belong to early periods of formation. The tuffs and many stones make up
the bulk of the cliffs to the south of the caldera.
The recent (1907) map of
Kapapala shows finely the distribution of this eolian deposit to the
south and southeast. Not less than twenty square miles have been covered
by it; extending for five miles southerly and southwesterly, or as far
as to the ancient cone of Koae. There are several volcanic cones such as
Kearaarea or Kamakaia in the midst of extensive fissures, both old and
new. To the south of Koae are many large sand dunes that have been blown
from the ash accumulations.
On the other side of the
fissures as one follows the regular road to Kau from Kilauea for nearly
four miles, there are numerous patches of fine-grained drab tuff from
two or three to six or more inches in extent with scoriaceous pieces and
pisolitic spherules which are less conspicuous than the others, but of
the same general character and age.
Similar materials may be
seen at the saw mill for koa lumber two miles from the Volcano House,
and for four or five miles towards Glenwood, so that he entire area
covered by the debris of explosive eruptions is estimated at more than
sixty square miles. They are six feet thick in the new road around
Kilauea iki. The following section has been made out:
At the surface, small
gravel stones with soil;
Gravel two feet thick;
Sand, becoming black
below;
Another foot thickness of
sand;
Pumice, a few inches
thick, sometimes in pockets ;
Rubble stones, some as
large as cobbles;
Underlying rock.
The black seams are
suggestive of a vegetable growth, indicating a lengthy period when
plants were able to spread naturally from ,the surroundings, only to be
covered later by the volcanic rain.
The enormous area thus
covered with explosive material renders it probable that the
comparatively mild discharge of 1790 was inadequate to account for so
extensive an inundation. There must have been several such discharges,
perhaps recurring during centuries of time. Only a tithe of the stones
spread over the surface would have been needed to destroy a much larger
detachment than that suffocated in 1790. It would seem more consonant
with the facts to connect the prolific tuffaeous and scoriaeous
discharges with the days of Liloa rather than of Keoua; and perhaps
Keanakakoi may have been the vent through which the discharge came.
Certain observations made
in 1905 may be significant here:
Opposite Keanakakoi in the
pit of Kilauea there was formerly exhibited upon the maps a "sulphur
bank," now mostly covered by the black ledge. A narrow promontory still
extends westerly to the south of Halemaumau, terminating at Kapuai and
only slightly elevated, and covered with eolian debris. At the southwest
end of the wall from Poli o Keawe there is an abrupt change from basalt
to scoriae, and as you climb to this rock from the gravel a marked fault
appears with a S.W. direction. On looking backwards there is a
noticeable dip of the layers towards the old sulphur bank-perhaps of ten
degrees. The fault seems to be the same with that figured by Professor
W. H. Pickering.
It seems apparent that the
tuffs came from Keanakakoi, unless they represent the inward slope of
the material blown out from Kilauea, such as falls toward the vent in
tuff cones. Most of the cliff encircling the south curve of Kilauea is
composed of similar materials.
Dr. Brigham speaks of
several shallow pits in this tuff that were made by the falling down or
washing into fissures the finer parts of the sand and gravel. All these
facts impress one with the magnitude and unusual character of the
materials erupted about Keanakakoi.
While there has been
uncertainty about the date and origin of the various Kau accumulations
of dust, it is refreshing to be able to present the views of Mr. E. D.
Baldwin, obtained recently as the result of his survey for the Kapapala
map. He finds that much of the fine volcanic ash has been derived from a
Kilauean source; while there were earlier discharges in lower Kau and at
Ka Lae not thus accounted for. These have been mentioned elsewhere in
connection with the history of Mauna Loa.

E. D. Baldwin upon the Yellow Ashes of Kau
As to the sources of the
yellow ash eruption, I would state, that I found a partial old yellow
cone in among the Kamakaia hills, or the hills some three miles back of
the Halfway House. The first source of the 1823 flow was three miles
above these hills, from a long fissure, and then it seems to have broken
out again, in its line of flow at these hills, forming the two larger
cones. Near the large cone are two ancient cones, surrounded by the new
lava, one of these was completely spattered and plastered over by the
ejections from the large cone; it was on this cone, while riding along
its base, that my horse broke through the crust, and while floundering
around for a footing brought up large quantities of yellow tufa, of
exactly the same nature as the black tufa, only it was of a beautiful
yellow ocher color. On investigation I found that a large portion of
this cone was composed of the same material.
About a mile below
Kamakaia hills, in the middle of the 1823 flow, is what we call the
yellow cone. This cone had attracted my attention several times from a
distance, as being of a yellowish color on all sides that we had
observed it from. I thought, of course, that like the little sharp cone,
Puu Kou, between it and the Kamakaia hills, it was a portion of the 1823
lava flow, but when we went out to the cone, we found that it was the
top of an old cone sticking up through the 1823 flow, which flow had run
all around the same, and into the crater of the cone. This cone was very
interesting, its formation was exactly the same as all of the dark
colored tufa cones, with the exception of color, which was entirely of
the yellow tufa, which, when crushed in the hand to fine powder, had
exactly the same appearance as the Kau yellow soils. In the crater of
the cone were the same brilliantly red tufas that you find in the
craters of all other cones. The top of the cone stands forty or fifty
feet above the 1823 flow, and must be several hundred feet in
circumference at the flow line. At this point the land lays more or less
level, with a gentle slope towards the sea, so that the 1823 flow seems
to have piled up to a great height and spread out to over a mile wide;
showing that this was a very large cone in its original state.
There are further
evidences of the yellow eruptions some ten miles from these cones
mentioned above. The great hill Puu Kapukapu, at the sea coast, is
largely composed of the Kau yellow soil, also just to the Kau side of
this hill, is the great hill Puu Kaone, having a low flat top,
containing sixty acres of first class agricultural land, composed
entirely of the Kau yellow soil of a depth of over thirty feet, as
observed in the little rain-washed gullies on the same. Also on the face
of the great pali or fault line, near the top, on a line towards
Kamakaia hills from Puu Kapukapu, I noticed a large yellow patch.
None of the sources of the
yellow eruptions, that I have mentioned, would account for the lower Kau
yellow soil, and that on the Kau side of Ka Lae or South Point, as the
prevailing winds in this district seem to sweep from the volcano
(Kilauea) down past the Kamakaia hills, and from there they meet the
winds coming around from the sea coast, which seem to turn the air
currents inland again.
My theory is, that at some
ancient period, there was a great line of yellow eruptions, extending
from Puu Kapukapu (near Keauhou), past the Kamakaia hills to the lower
portion of Kau, and that the sources of this yellow eruption in the
lower part of Kau have been covered up with later flows, or other
volcanic action, and that the great beds of yellow soil that we find
today all over Kau, were blown there from these sources, before they
were covered up. All of the yellow soil on the Pahala plantation, or
towards the volcano from Pahala, is directly on the line of the
prevailing winds from the direction of Kamakaia hills, Yellow cone, and
a short ways below the same. I have especially noticed in the cuts on
the Volcano-Kau road, just above the Pahala mill, that the old aa
formation seems to be full of this yellow dust. If one will go and study
the action of the wind on the great masses of volcanic sand being blown,
at present, from Kilauea towards Kamakaia hills, it will be noted that
when this sand strikes an aa flow, its forward progress is stopped,
until it has filled and sifted into all of the little crevices of the
aa. From Kilauea to near Kamakaia hills is a nearly barren field of
pahoehoe, and the sand is driven along this space at a great pace, until
it reaches the aa at the Kamakaia hills, and there it has been blocked
up and is in many cases forming numerous sand dunes. Some of these sand
dunes are very extensive, being four or five hundred feet long and over
fifty feet high.

Ellis' Description of Kilauea
The first edition of the
Journal of the Tour Around Hawaii was published in 1825. Eight
years later it was reprinted with additions and emendations as
Polynesian Researches, in four volumes and some of the original
statements were modified. There were English editions also. I will
utilize the additions and corrections given in the later edition.
"We found ourselves," he
says, "on the edge of a steep precipice (Uwekahuna) with a vast plain
before us, seven and one-half miles in circumference, and sunk at least
eight hundred feet below its original level. The surface of this plain
was uneven, and strewed over with large stones and volcanic rocks. A
place was found at the north end where a descent to the plain below was
found practicable, and even yet the stones gave way under their feet
causing them to fall and receive bruises. The rocks were of a light red
and gray lava, vesicular, and lying in horizontal strata, varying in
thickness from one to forty feet. In a small number of places the
different strata of lava were also rent in perpendicular or oblique
directions, from the top to the bottom, either by earthquakes or other
violent convulsions of the ground connected with the action of the
adjacent volcano. The immense gulf has the form of a crescent two miles
long from northeast to southwest and a mile in width. The bottom was
covered with lava, and the southwest and northern parts of it were one
vast flood of burning matter, in a state of terrific ebullition, rolling
to and fro its "fiery surge" and flaming billows. Fifty one conical
islands (spiracles), of varied form and size, containing as many
craters, rose either round the edge or from the surface of the burning
lake. Twenty-two constantly emitted columns of gray smoke or pyramids of
brilliant flame; and several of these at the same time vomited from
their ignited mouths streams of lava, which rolled in blazing torrents
down their black indented sides into the boiling mass below."
Next follows a paragraph
added in the later edition, a theoretical deduction. "The existence of
these conical craters led us to conclude that the boiling caldron of
lava before us did not form the focus of the volcano; that this mass of
melted lava was comparatively shallow; and that the basin in which it
was contained was separated, by a stratum of solid matter, from the
great volcanic abyss, which constantly poured out its melted contents
through these numerous craters into this upper reservoir. We were
further inclined to this opinion from the vast column of vapor
continually ascending from the chasms in the vicinity of the sulphur
banks and pools of water, for they must have been produced by other fire
than that which caused the ebullition in the lava at the bottom of the
great crater; and also by noticing a number of small craters in vigorous
action, situated high up the sides of the great gulf, and apparently
quite detached from it. The streams of lava which they emitted rolled
down into the lake and mingled with the melted mass, which, though
thrown up by different apertures, had perhaps been originally fused in
one vast furnace.''
"The sides of the gulf
before us, although composed of different strata of ancient lava were
perpendicular for about (nine) hundred feet (as calculated by Lieut.
Malden later) and rose from a wide horizontal ledge of solid black lava
of irregular breadth, but extending completely round. Beneath this ledge
the sides sloped gradually towards the burning lake, which was, as
nearly as one could judge, three or four hundred feet lower. It was
evident that the large crater had been recently filled with liquid lava
up to the black ledge, and had by some subterranean canal emptied itself
into the sea, or upon the lowland on the shore." And he goes on to
suggest that this discharge was what they had seen at Ponahoahoa a short
time previously. This eruption is reported at one time two moons and at
another five moons earlier than that date of August 1st. I have already
presented a figure illustrating this flow to the southwest.
It has been difficult to
be entirely satisfied with some of the details offered in this sketch,
because of repetitions, and of differences in the accompanying sketches.
The first are explained by the supposition that to the original
statement additions were made by others of the party; and the second may
be due to the artist or engraver who make changes to suit fancy. The
earlier account of all the Hawaiian volcanoes have been more or less
influenced by a supposed similarity to Vesuvius. Instead of reproducing
the sketches, I will present a restoration of what seem to me to be the
true delineation of the cliffs, the black ledge and the lakes of fire,
as they appeared in 1823, Plate 27B. The verbal description of the
volcano given above by Mr. Ellis represents things as seen from
Uwekahuna, but the views published must have been taken from the
opposite side of the pit, showing the place on which he stood when he
obtained his impressions.
The descriptions of the
two sulphur banks correspond to what have been seen later by others. The
one at the north end was said to be about one hundred and fifty yards
long, and thirty feet high at the maximum, showing much sulphur mixed
with red clay. The ground was hot; fissures seamed the surface through
which thick vapors continually ascended. Fine crystals of sulphur
appeared in acicular light yellow prisms near the surface; those lower
down were of an orange-yellow color in single or double tetrahedral
pyramids an inch long. Ammonium sulphate, alum and gypsum frequently
incrusted the stems. The other sulphur bank was larger and the sulphur
more abundant, but they did not find time to examine it carefully. Both
these banks correspond to what is now called a solfatara.
The view by night was
impressive. "The agitated mass of liquid lava, like a flood of melted
metal, raged with tumultuous whirl. The lively flame that danced over
its undulating surface, tinged with sulphureous blue, or glowing with
mineral red, cast a broad glare of dazzling light on the indented sides
of the insulated craters, whose roaring mouths, amid rising flames and
eddying streams of fire, shot up, at frequent intervals, with very loud
detonations, spherical masses of fusing lava or bright ignited stones."
Mr. Ellis correctly named
the rock, calling it basalt containing fine grains of feldspar and
augite, with olivine. He also found zeolites and described the volcanic
glass called Pele's hair by the natives. He conceived it to have been
produced by a separation of fine spun threads from the boiling fluid,
and when borne by the smoke above the edges of the crater had been
wafted by the winds over the adjacent plain. He examined several of the
small craters, which from above had appeared like mole hills, and found
them to be from twelve to twenty feet high. The outside was composed of
bright shining scoria and the inside was red with a glazed surface. He
also entered several tunnels through which the lava had flowed into the
abyss, and correctly ascribes their origin to the formation of the roof
and sides by the cooling of the exterior, while the liquid for a time
continued to flow in the inside. Professor Dana thinks that the fan
figured on the west wall in the first sketch of the south end of the
volcano was one of these tunnels, but it seems to me that it was only a
fan of gravelly scoriae. It appeared as an isolated cone in the second
sketch, detached from the wall, probably because the engraver did not
know what else to do with it. Dr. S. E. Bishop tells me that this fan
was very conspicuous when he first visited the volcano seventy years
ago, and at his suggestion I looked for it in 1905 and could identify
its location. Probably the tunnels were upon the eastern side, where
later flows, such as those made in 1832, are still in evidence. These
tunnels were represented as being hung with red and brown stalactitic
lava, while the floor appeared like one continued glassy stream. The
riffle of the surface was as well defined as if the lava had suddenly
stopped and become indurated before it had time to settle down to
horizontality.
It would appear from what
has been stated that there was more than one lake of fire at this time,
and that there was a great abyss into which the surplus lava from the
higher lake and the streams through the tunnels had accumulated. Mr.
Ellis also speaks of the two side craters Keanakakoi and Kilauea iki,
thus proving that these names were in use in 1823, and he seems to have
been the originator of the expression "black ledge," which represented
the level assumed by the molten lava before the recent discharge to the
southwest. He speaks of many masses of grey basaltic rock, weighing from
one to four and five tons, and surmised that they had been ejected from
the great crater during some violent eruption. Not to present more of
his truthful descriptions, I will refer only to his final speculation of
the extent of the present subterranean fires. The whole island of Hawaii
was said to be "one complete mass of lava, or other volcanic matter in
different stages of decomposition. Perforated with innumerable apertures
in the shape of craters, the island forms a hollow cone over one vast
furnace, situated in the heart of a stupendous submarine mountain,
rising from the bottom of the sea," etc.

The Belief in Pele
The apprehensions
uniformly entertained by the natives of the fearful consequences of
Pele's anger prevented their paying very frequent visits to the vicinity
of her abode; and when, on their inland journeys, they had occasion to
approach Kilauea, they were scrupulously attentive to every injunction
of her priests, and regarded with a degree of superstitious veneration
and awe the appalling spectacle which the crater and its appendages
presented. The violations of her sacred abode, and the insults to her
person, of which we had been guilty, appeared to them, and to the
natives in general, acts of temerity and sacrilege; and, notwithstanding
the fact of our being foreigners, we were subsequently threatened with
the vengeance of the volcanic deity under the following circumstances.
"Some months after our
visit to Kirauea, a priestess of Pele came to Lahaina, in Maui, where
the principal chiefs of the islands then resided. The object of her
visit was noised abroad among the people, and much public interest
excited. One or two mornings after her arrival in the district, arrayed
in her prophetic robes, having the edges of her garments burnt with
fire, and holding a short staff or spear in her hand, preceded by her
daughter, who was also a candidate for the office of priestess, and
followed by thousands of the people, she came into the presence of the
chiefs; and having told who she was, they asked what communications she
had to make. She replied that, in a trance or vision, she had been with
Pele, by whom she was charged to complain to them that a number of
foreigners had visited Kilauea; eaten the sacred berries; broken her
houses, the craters; thrown down large stones, etc. to request that the
offenders might be sent away and to assure them, that if these
foreigners were not banished from the islands, Pele would certainly in a
given number of days, take vengeance, by inundating the country with
lava, and destroying the people. She also pretended to have received in
a supernatural manner, Rihoriho's approbation of the request of the
goddess. The crowds of natives who stood waiting the result of her
interview with the chiefs were almost as much astonished as the
priestess herself, when Kaahumanu, and the other chiefs, ordered all her
paraphernalia of office to be thrown into the fire, told her the message
she had delivered was a falsehood, and directed her to return home,
cultivate the ground for her subsistence, and discontinue her deceiving
the people.
This answer was dictated
by the chiefs themselves. The missionaries at the station, although they
were aware of the visit of the priestess, and saw her, followed by the
thronging crowd, pass by their habitation on the way to the residence of
the chiefs, did not think it necessary to attend or interfere, but
relied entirely on the enlightened judgment and integrity of the chiefs,
to suppress any attempt that might be made to revive the influence of
Pele over the people; and in the result they were not disappointed, for
the natives returned to their habitations, and the priestess soon after
left the island, and has not since troubled them with threatenings of
the goddess.
"On another occasion,
Kapiolani, a royal princess, the wife of Naihe, chief of Kaavaroa, was
passing near the volcano, and expressed her determination to visit it.
Some of the devotees of the goddess met her and attempted to dissuade
her from her purpose; assuring her that though foreigners might go there
with security, yet Pele would allow no Hawaiian to intrude. Kapiolani,
however, was not to be thus diverted, but proposed that they should all
go together; and declaring that if Pele appeared, or inflicted any
punishment, she would then worship the goddess, but proposing that if
nothing of the kind took place, they should renounce their attachment to
Pele, and join with her and her friends in acknowledging Jehovah as the
true God. They all went together to the volcano; Kapiolani, with her
attendants, descended several hundred feet towards the bottom of the
crater, where she spoke to them of the delusion they had formerly
labored under in supposing it inhabited by their false gods; they sang a
hymn, and after spending several hours in the vicinity, pursued their
journey. What effect the conduct of Kapiolani, on this occasion, will
have on the natives in general, remains to be discovered."

KAPIOLANI
(Kapiolani was the daughter of Keawemauhile, the former king of Hilo,
slain by Keoua in 1790.)
By Alfred Lord Tennyson
When from the terrors of nature a people
Have fashioned and worshipped a Spirit of Evil,
Blest be the voice of the teacher who calls to them,
"Set yourselves free!"
Noble the Saxon who hurled at his idol
A valorous weapon in olden England!
Great, and greater, and greatest of women,
Island heroine, Kapiolani,
Clomb the mountain, and flung the berries,
And dared the Goddess, and freed the people
Of Hawaii!
This people believing that Pele the Goddess,
Would swallow in fiery riot and revel
On Kilauea,
Dance in a fountain of flame with her devils,
Or shake with her thunders and shatter her island,
Rolling her anger
Through blasted valleys and flowing forest
In blood-red cataracts down to the sea!
Long as the lava light glares from the lava lake,
Dazing the starlight;
Long as the silvery vapor in daylight
Over the mountain floats, will the glory
Of Kapiolani be mingled with either
On Hawaii.
What said her Priesthood,
"Woe to this island if ever a woman should handle
Or gather the berries of Pele! Accursed were she!
And woe to this island if ever a woman
Should climb to the dwelling of Pele the Goddess!
Accursed were she!"
One from the sunrise dawned on His people,
And slowly before Him vanished shadow-like
Gods and Goddesses,
None but the terrible Pele remaining,
As Kapiolani ascended her mountain,
Baffled her priesthood, broke the tabu,
Descended the crater,
Called on the Power adored by the Christian,
And crying, "I dare her! Let Pele avenge herself!"
Into the flame dashed down the berries,
And drove the demon from Hawaii!

The True Story of Pele
King Kalakaua recovered
from the traditions handed down for many generations the true story of
Pele, and has presented it in his book under the heading of The
Apotheosis of Pele. It seems that there was a large family, five
brothers and nine sisters, emigrating from Tahiti during the reign of
Kamiole the usurper about A.D. 175.
Their names are given by
Ellis as follows: Kamohoarii; Tapohaita hiora (the explosion in the
place of life); Teuaatepo (the rain of night); Tanehetiri (husband of
thunder or thundering Tane) and Teoahitamatana (fire-thrusting child of
war). These were all brothers, two of them like Vulcan being humpbacked.
The sisters were Pele, the
principal goddess; Makorewawahiwa (fiery-eyed canoe breaker);
Hiataholani (heavenrending cloud holder); Hiatanoholani
(heaven-dwelling cloud holder); Hiatata aravamata (quick-glancing-eyed
cloud holder, or the cloud holder whose eyes turn quickly and look
frequently over her shoulders); Hiatahoiteporiopele (the cloud holder
embracing or kissing the bosom of Pele); Hiatatabuenaena (the red-hot
mountain holding or lifting clouds); Hiatatareia (the weather
'garland-encircled cloud holder); and Hiataopio (young cloud holder).
This family with many
others in their train settled about Kilauea. Pete was a valiant warrior.
Kamapuaa was attracted by the merits of Pele, visiting Kilauea, and made
proposals to become her guest and suitor. In many of the annals he is
represented as half human and half hog-but Kalakaua explains that he was
simply a rough, stalwart man with coarse black bristly hair of
unprepossessing appearance, and called a half hog in derision. Pete
rejected his proposals with contempt, calling him a hog and the son of a
hog. A combat ensued, and the Pele family were worsted, and retreated to
one of the long volcanic tunnels marking the course of an earlier lava
flow ,and the entrance was closed. The party consisted of two men and
eighteen women and children. Kamapuaa finally discovered the retreat and
dug down into it from above. Just then there came a flow of lava which
drove away the besiegers, who believed the people within the cave had
been destroyed. Because of this timely eruption it was believed that
Pele had the power of calling up the fire, and she became apotheosized
as a goddess. As time went on the various eruptions were ascribed to
some of Pete's movements. The whole island was considered bound to pay
tribute; and if the proper offerings were not given to her votaries the
caldera would be filled with lava and made to follow the delinquents.

Kilauea in 1824
In 1824 Kilauea was
visited by E. Loomis, June 16th, who came from the southwest. After
reaching a point two miles from the crater he was annoyed by smoke
blowing in his face, accompanied by sulphur fumes. The air, too, was
filled with fine particles of sand, rendering it necessary to protect
his face from their impact; and the surface of the ground was covered by
it, his feet sinking into it six or eight inches at every step. From
crevices five miles west of the crater smoke was issuing, and
occasionally the forced ejection was great enough to produce an
irregular hissing sound. At the southwest end of the volcano the smoke
was so dense that little could be seen, and farther on much rain fell.
He took the road on the east side. From two hundred and fifty to three
hundred feet below the edge was a level platform, extending entirely
around the crater, which was evidently the "black ledge" of Ellis. This
platform was fifteen rods wide where he descended, probably near the
"sulphur banks" as now designated. He had little difficulty in reaching
the black ledge. Having now descended six hundred feet, Mr. Loomis
walked upon the lower platform whose surface was smooth, though not
level, rising in heaps like cocks of hay and broken by innumerable
fissures.
The lava was black, porous
like pumice, and traversed by crevices emitting very hot steam.
Proceeding eight or ten rods he reached another escarpment of two
hundred or three hundred feet deep leading to the floor of the most
active portion, from which smoke and flames of fire were issuing. There
seemed to be small craters (spiracles) where the fire burst forth
attended by a horrid noise. He was quite disappointed in not finding
this lowest platform a mass of liquid fire, as it had been the year
previous. The surface had become hard, and he presumed he could have
walked over it safely but he did not descend to it as the sides were too
steep to allow of a comfortable passage. This record is quite important,
as it shows a period of comparative quiet at the center of eruption
following the intense activity reported by Ellis in the previous year.

Visit of Lord Byron
In the year 1825, July
28th, a party from the "Blonde" visited the crater, Lord George Anson
Byron being the leader. Others were Rev. C. C. Stewart and Lieut.
Malden, the historians, and R. Dampier, the artist.
The hut used by the
company was situated upon the narrow plain between Kilauea and Kilauea
iki. It had been erected a year or two earlier for the accommodation of
Kapiolani. Lieut. Malden calculated the height of the upper cliff,
Uwekahuna, to be nine hundred feet above the black ledge, and the depth
of the lower pit at six hundred feet, a total of 1,500 feet. The
circumference of the edge of the black ledge was from five to seven
miles and that of the top from eight to ten miles
Mr. Stewart speaks of the
black ledge as a kind of gallery, in some places only a few feet, in
others many rods wide. The gulf below contains as many as sixty small
conical craters, many in constant action. The tops and sides of two or
three of these are covered with sulphur, showing mingled shades of
yellow and green. The upper cliffs on the northern and western sides are
of a red color. Those on the eastern side are less precipitous and are
largely composed of sulphur. The south end was wholly obscured by smoke
which was impenetrable. The chief seat of action seemed to be at the
southwestern end (Halemaumau). To the north of this is one of the
largest of the smaller craters-one hundred and eighty feet high-an
irregularly shaped inverted funnel of lava covered with clefts, orifices
and tunnels, from which bodies of steam escaped with deafening
explosion, while pale flames, ashes, stones and lava were propelled with
equal force and noise from its ragged and yawning mouth.
On the evening of
the following day (29th) after terrific noises and tremblings of the
ground, "a dense column of heavy black smoke was seen rising from the
crater directly in front of us the subterranean struggle ceased and
immediately afterwards flames burst front a large cone, near which we
had been in the morning, and which then appeared to have been long
inactive. Red-hot stones, cinders and ashes, were also propelled to a
great height with immense violence; and shortly after the molten Java
came boiling up, and flowed down the sides of the cone and over the
surrounding scoriae, in two beautifully curved streams." At the same
time a lake of molten lava two miles in circumference made it
appearance.
Rev. Artemas Bishop, in
December, states that the pit was not so deep as in 1823 at the time of
Ellis' visit by as much as four hundred feet. There were also Jakes of
lava, frequently discharging gusts of vapor and smoke with great noise.
As an evidence of oft repeated eruptions from Kilauea, the natives
remarked to Mr. Bishop, that after rising a little higher the lava would
discharge itself towards the sea through some subterranean aperture.
Rev. Mr. Stewart
visited Kilauea again in October, 1829. The lower pit had been filled up
more than two hundred feet, and there was more fire at the northern end.
Many of the cones had disappeared, but he was greatly interested in two
of them each one about twenty feet high tapering from a point above
to a base sixty feet in circumference. They were hollow, with steam,
vapors and flame issuing from crevices and roaring so as to merit the
appellation of "blow holes," or "spiracles," as named by G. Paulett
Scrape.

Visit of Hiram Bingham
Rev. Hiram Bingham spent
thirty hours at the volcano October 20th and 21st, 1830. He represented
the altitude to be 4,000 feet, ten thousand below Mauna Loa. Six hundred
feet below the rim "stretched around horizontally a vast amphitheater
gallery of black indurated lava," on which a hundred thousand people
might stand. The lake of fire was one thousand feet deep. "The fiercely
whizzing sound of gas and steam, rushing with varying force through
obstructed apertures in blowing cones, or cooling crusts of lava, the
laboring, wheezing struggling, as of a living mountain, breathing fire
and smoke and sulphurous gas from his lurid nostrils, tossing up molten
rocks or detached portions of fluid lava, and breaking up vast indurated
masses with varied detonations, all impressively filled us with awe.
"The great extent of the
surface of the lava lake; the numerous places on it where the fiery
element was displaying itself, the conical mouths here and there,
discharging glowing lava over flowing and spreading its waves around,
or belched out in detached and molten masses that were shot forth with
detonations, perhaps by the force of gases struggling through from below
the surface, while the vast column of vapor and smoke ascended up toward
heaven ,and the coruscations of the emitted brilliant lava illuminated
the clouds that passed over the terrific gulf, all presented by night a
splendid and sublime panorama of volcanic action, probably nowhere else
surpassed."
He descended from the
northeast side to the black ledge, and to the lava lake, which
"presented cones, mounds, plains, vast bridges of lava recently cooled,
pits and caverns, and portions of considerable extent in a movable and
agitated state." Near the center is a large mound, from the top of which
lava poured out in every direction in a series of circular waves. The
outermost wave solidifies, when another one follows, perhaps passing
over the first; then others follow as if in a series of pulsations from
the "earth's open artery" at the top of the mound.
The capillary glass was
observed, and its formation understood. "It is formed, I presume, by the
tossing off of small detached portions of lava of the consistence of
molten glass, from the mouths of cones, when a fine vitreous thread is
drawn out between the moving portion and that from which it is detached.
The fine spun product is then blown about by the wind, both within and
around the crater, and is collected in little locks or tufts."
In July, 1831, Mr.
Goodrich visited Kilauea and says that "the crater had been filled up to
the black ledge, and about fifty feet above it, about nine hundred feet
in the whole," since his first visit in 1823.
Back to Contents
Eruption of 1832
The accounts of the
eruption of 1832 are sufficiently full to enable us to know that the
disturbances in Kilauea near the lakes of fire correspond to those
manifested at other eruptive periods. According to the statements that
have already been cited, the lower pit had been filled up with lava to
the amount of nine hundred feet since the discharge of 1823. Rev. Joseph
Goodrich visited the locality in November and says that the lava "had
now again sunk down to nearly the same depth as at first, leaving as
usual a boiling caldron at the south end. The inside of the crater had
entirely changed.
In January
preceding-about the 12th as nearly as I can ascertain the volcano
commenced a vigorous system of operations, sending out volumes of smoke;
and the fires so illumined the smoke that it had the appearance of a
city enveloped in one general conflagration." A day or two later there
were six or eight smart earthquakes, repeated for two or three days.
These may have been concerned more particularly with the emissions on
the plain between the two craters of Kilauea and Kilauea iki.
On descending into the
caldera, Mr. Goodrich speaks of the molten lava at the south end "an
opening in the lava sixty to eighty rods long, and twenty or thirty
wide." About twenty feet below the brink this liquid mass was "boiling,
foaming and dashing in billows against the rocky shore. The mass was in
motion, running from north to south at the rate of two or three miles an
hour; boiling up as a spring at one end, and running to the other." He
speaks of this mass as a lake, and says that the liquid lava is
incrusted by its own cooling, just as ice is formed over rivers in cold
climates. As the ice in rivers crashes against the shores, so this crust
is forced against the bank and distorted. The lava crusts melt and
reform while "gaseous matter is forced through, scattering the liquid
fire in every direction." There were also two islands in this lake.
This, however, must have
been after the discharge of the liquid from the bottom of the pit. There
is absolutely no testimony from any source, of this eruption, save the
statement that it ran away about January 12th. Whether it appeared at
the surface, filled up some subterranean cavity or flowed under the sea
is entirely unknown. Before its disappearance the lava rose about fifty
feet above the black ledge of 1823, thus building up a platform believed
to be nine hundred feet above the molten lake.
From Mr. Goodrich's
statements the depth of the bottom must have been 1,750 feet from the
top of the wall. This is confirmed by an entry in the private diary of
Rev. W. P. Alexander who visited the volcano January 12, 1833, two
months later than Mr. Goodrich, who says the crater was two thousand
feet deep. He does not speak of any black ledge; whence it is inferred
that this terrace must have been very narrow, as in 1823. Mr. Alexander
was disappointed in not finding the principal furnace in lively action
while he was at the bottom of the pit; but by the time he had returned
to the summit a furious action had commenced and molten lava spouted far
into the air with a roaring sound. The following day the boiling caldron
was found to be 3,000 feet long, 1,000 wide, and spouting in jets forty
or fifty feet high.
The manifestations of
igneous activity in another part of the area, at this time, January,
1832, as reported by Mr. Goodrich and confirmed by later observations of
the effects produced, were unlike any others that have been seen at
Kilauea. "The earthquakes rent in twain the walls of the crater on the
east side from the top to the bottom, producing seams from a few inches
to several yards in width, from which the region around was deluged with
lava. The chasms" (were developed) "within a few yards of where Mr.
Stewart, Lord Byron, myself and others had slept," the spot being the
"Hut" on Malden's map, "so that the spot where I have lain quietly many
times is entirely overrun with lava." Back of it, at right angles with
the main chasm, and about half way up the precipice, there was a vent a
quarter of a mile in length from which the lava issued which had
destroyed the Hut. This fissure thus was parallel with the edge of
Kilauea
Upon Mr. Dodge's map the
lava is represented as starting from an orifice below the edge of Poli o
Keawe, spreading out like a fan so as to include the Hut, and then
turning westerly so as to pour into Kilauea; and there was so much of it
that it makes a tongue-like projection into the contour of the lower
plain just at the northern end of the sulphur banks. Professor Dana was
greatly impressed by the appearance of these cooled and hollow streams,
as he saw them in 1840. "The angle of descent of these streams was about
thirty-five degrees; and yet the streams were continuous. The ejection
had been made to a height of four hundred feet at a time when the pit
below was under building lavas and ready for discharge. Elsewhere about
the upper walls, and also about those of the lower pit, no scoria was
seen. The surfaces of walls are those of fractures, brought into sight
by subsidences; and the rocks of the layers were as solid as the most
solid of lavas. Moreover, no scoria intervened between the beds of lava
even in the walls of the lower pit, each new stream having apparently
melted the scoria-crust of the layer it flowed over; and no beds of
cinders or volcanic ashes were anywhere to be seen in alternation with
the beds of lava. While the cooled lava streams over the bottom were of
the smooth-surfaced kind, and would be called pahoehoe, there was the
important distinction into streams having the scoria-crust just
mentioned, and those having the exterior solid with no separate crust
facts that pointed to some marked difference in conditions of origin."
The floor of Kilauea iki
is covered by as many as fifty hummocks fifteen or twenty feet high.
They arrested the attention of Professor W. H. Pickering in 1905, who
conceives them to illustrate the process of construction of Kilauea
itself as well as elevations on the surface of the moon. He says, "The
surface of the crater floor of Kilauea iki seems to have solidified into
a layer six to ten inches in depth and distinct from the portions below
it. A liquid core forced up from below raised this surface layer
locally, and shattered it into separate pieces like cakes of ice. This
core in the case of the smaller craterlets was sometimes only two or
three feet in diameter, and could be seen beneath the shattered surface.
In one instance its summit seemed to have an almost globular form, five
feet in diameter. If the volcanic forces beneath these craterlets had
been more intense, it is probable that the issuing lava would have
completely destroyed them, forming a series of crater pits into which
the lava would have subsequently retreated. In the southwest part of the
floor two such pits were found, perhaps fifteen feet in depth by thirty
in diameter, down into which a stream of lava had poured, but had
solidified without filling them up."
Kilauea iki, according to
Mr. Dodge's map, is 3,300 feet from east to west and 2,800 feet from
north to south, and is seven hundred and forty feet deep, or eight
hundred and sixty-seven feet below the Volcano House, from which it is
about a mile distant. It is best reached by descending the north wall,
making use of ropes in the steepest part of the slope. It is now (1909)
encircled by a carriage road from the Volcano House.
This was the original name
given to it by the natives, iki, meaning little, and was used by Mr.
Ellis in his Journal, and by most travelers. Professor Brigham called it
Poli o Keawe, and applied the Kilauea iki to Keanakakoi; and was
followed by Captain Dutton. On questioning reliable natives in 1883
about the nomenclature, I found that Mr. Ellis was right in his early
application of these names, and that the expression Poli o Keawe,
signifying the bosom of Keawe, should be applied to the bluff
overlooking Kilauea between the two side pits. Keanakakoi was derived
from ana, a cave, and koi an axe or adze: meaning a chipping axe cave,
because stone implements had been manufactured here in primitive times.
The same name is applied to the famous locality for the manufacture of
implements situated near the summit of Mauna Kea.
On further investigation I
have discovered that Professor Brigham has improperly represented that
Mr. Goodrich endorsed two names relating to Kilauea. The first is
Halemaumau and the second is Poli o Keawe. He has made an abstract of
Mr. Goodrich's statement, as partially quoted above, into two sentences
amounting to seventy-eight words, including the two geographical names,
and has included the whole in quotation marks. Neither of the
expressions Halemaumau or Poli o Keawe were used by Mr. Goodrich,
although he describes both the localities. Professor Brigham probably
did not intend to intimate that Mr. Goodrich used the words indicated.
It is worthy of note that
for a short time eruptions may have taken place simultaneously from
Kilauea and Mokuaweoweo in 1832. The first one commenced action January
12th and the second June 20th. We have, however, no definite statement
from any one that the discharge from Kilauea continued as late as to the
opening of the fire streams upon Mauna Loa, though it is not improbable.

Between
1832 and 1840
The next visit to Kilauea
recorded was by Mr. David Douglass in 1834. He found two molten lakes
the more northern three hundred and nineteen yards in diameter; the more
southern, 1,190 x 700 yards in extent, and heart-shaped. The larger one
occasionally boiled with terrific grandeur, throwing up jets estimated
to be from twenty to seventy feet high. Nearby stood a chimney forty
feet high, which occasionally discharged its steam as if all the
steam-engines in the world were concentrated in it." Professor Dana says
this is a good description of a blowing cone, though this name had not
been used so early. Mr. Douglass measured the velocity of the movement
in the lava by timing the rapidity of blocks of stone thrown upon the
surface of the stream, just as one may estimate the velocity of water by
the chips upon the top. This proved to be nearly three and a quarter
miles per hour. Mr. Douglass used the barometer to determine the depths
of the black ledge and pit. As the mean of two calculations he found the
depth from Uwekahuna to the former to be seven hundred and fifteen feet,
and to the bottom of the pit 1,077 feet, or three hundred and sixty-two
feet below the black ledge. In addition to this he said it was
forty-three feet more to the liquid lavas. This proves that there had
been a renewal of the lava from the pit in 1832, and his other
observations represent that the lower portion was larger and deeper than
after the eruption of 1840. Douglass has been discredited because he
seemed to have exaggerated the size and activity of Mokuaweoweo in a
letter written to Dr. Hooker, dated three days later than the very
reasonable account of the phenomena mentioned above. It has been
suggested that he wrote the latter under the influence of temporary
hallucination.
Charles Burnham says the
crater was eight hundred feet deep over the whole surface in 1835 with
no cones over seventy-five feet high. A very large lake visible from the
hut. From the record book June 17, 1881.
In August, 1837
Mr. S. N. Castle of
Honolulu visited Kilauea, and reported that the lower pit below the
black ledge was nearly filled up, and he also found active cones in all
parts of the caldera.
In May, 1838
Captains Chase and Parker
visited the volcano and some account of their trip was compiled by E. C.
Kelley for the American Journal of Science. The lavas had nearly
filled up the lower pit. Over its floor, about four square miles in
extent, there were twenty-six cones, eight of which were throwing out
cinders and molten lava. Six small lakes were in evidence. The largest
one was probably identical with the later Halemaumau, upon whose surface
an island of solid lava "heaved up and down in the liquid mass, and
rocked like a ship on a stormy sea." They also noted the oscillations in
the heat, so obvious to later visitors. The lake which had been boiling
violently became covered by a mass of black scoriae; but this
obscuration was temporary, for very soon this crust commenced cracking,
black plates floated upon the surface like cakes of ice upon water, and
probably disappeared. At the last moment of observation about a quarter
of the floor gave way and became a vast pool of liquid lava.
An elaborate drawing of
the volcano as it seemed at that time accompanies the sketch, prepared
by a New York artist, who evidently incorporated into it the features of
Vesuvius. It was taken from the south end, shows the great south lake
and the floating island, and is of value because it indicates the nearly
complete obliteration of the black ledge.
In August or September of
the same year Count Strzelecki measured the height of the
north-northeast wall with a barometer, finding it to be six hundred
feet. Nothing is said about the black ledge, whence it may be inferred
that it was not visible. Six craters filled with molten lava are
mentioned, four of them three or four feet high, one forty feet and the
other one hundred and fifty. Five of these had areas of twelve thousand
feet each; and the sixth contained nearly a million and had the name of
Haumaumau, and was encircled by a wall of scoriae fifty yards high. He
said that the lava rose and sunk in all the lakes simultaneously an
observation that has never been confirmed in the later history. The
language descriptive of the craters filled with lava might be
interpreted to correspond with the occasional manifestation of a lake
supported upon a rim consisting of the cooled liquid, as shown
particularly in 1894. Like Mr. Douglass Count Strzelecki has given in
the Hawaiian Spectator a more extravagant account of Kilauea, besides
the reasonable one abridged above from a book upon New South Wales and
Van Diemen's Land published seven years later. He was the first author
to use the name Hau-mau-mau (Halemaumau).
The latest visit to the
volcano previous to the great eruption in 1840 was made by Captain John
Shepherd, R. N., September 16, 1839. He mentions several cones and small
lakes on the floor of the pit on the way to the great lake. The black
ledge was "obliterated": there were cones twenty to thirty feet high
emitting lava and vapors with loud detonations; and the Great Lake,
supposed to be Halemaumau, though incorrectly stated to be on the east
side, was a mile and a half long, within a cone a hundred r88 feet high.
There was an apparent flow of the liquid from south to north and spray
thrown up from thirty to forty feet.

The Eruption of 1840
This was the most
important of all the discharges from Kilauea since the country has been
known to us. Our sources of information are the statements of Rev. Titus
Coan, Captain Charles Wilkes and Professor J.D. Dana. None of these
gentlemen were on the spot at the time, but obtained their information
from good authorities while the phenomena were fresh in mind.
Rev. Mr. Coan happened to
be absent in Oahu at the time of the eruption. He had visited the
volcano before and was familiar with its features; so that he was
qualified to test the statements of the natives. The great basin below
the black ledge had been filled to overflowing, and as much as fifty
feet thickness had accumulated above the platform. The whole area of the
pit is represented as an entire sea of ignifluous matter, with waves
dashing against the walls sufficiently energetically as to detach great
masses of the overhanging rocks. No one dared to approach near the fiery
mass. Mr. Coan believed the statements correct, because not a single
part of the lava seen after the eruption was like what had been visible
before: all had been melted down and recast.
It was May 30th when the
inhabitants of Puna first observed indications of fire. On the following
day the fire greatly augmented. On the third day, June 1st, the lava
began to flow off in a northeasterly direction. By the evening of June
3rd the burning river had reached the sea and discharged over a cliff
near Nanawale for three weeks. There were slight and repeated shocks of
earthquakes near the volcano, for several successive days; but none were
noticed at Hilo.
The first appearance of
the lava was at a small pit about six miles distant from Kilauea, in the
forest. The lava rose in this opening about three hundred feet, and then
sank down when there was a discharge below. Remnants of this material
were observed by Mr. Coan. Then there were other small ejections in
fissures nearby. Others appeared, some two or three miles away, and
finally upon June 1st began the principal outflow, twenty-seven miles
from Kilauea, eleven from the sea, and 1,244 feet above tide water. A
further account of the eruption is given in the words of Mr. Coan:
The source of the
eruption is in a forest and was not discovered at first, though several
foreigners have attempted it.
"From Kilauea to this
place the lava flows in a subterranean gallery probably at the depth of
a thousand feet, but its course can be distinctly traced all the way, by
the rending of the crust of the earth into innumerable fissures and by
the emission of smoke, steam and gases. The eruption in this
old crater is small, and from this place the stream disappears again for
the distance of a mile or two when the lava again gushes up and spreads
over an area of about fifty acres. Again it passes underground for two
or three miles, when it reappears in another old wooded crater,
consuming the forest and partly filling up the basin.
Once more it disappears,
and flowing in a subterranean channel, cracks and breaks the earth,
opening fissures from six inches to ten or twelve feet in width, and
sometimes splitting the trunk of a tree so exactly that its legs stand
astride at the fissure. At some places it is impossible to trace the
subterranean stream on account of the impenetrable thicket under which
it passes. After flowing underground several miles, perhaps six or
eight, it again broke out like an overwhelming flood, and sweeping
forest, hamlet, plantation and everything before it, rolled down with
resistless energy to the sea, where leaping a precipice of forty or
fifty feet, it poured itself in one vast cataract of fire into the deep
below, with loud detonations, fearful hissings, and a thousand unearthly
and indescribable sounds.
Imagine to yourself a
river of fused minerals, of the breadth and depth of Niagara, and of a
deep gory red, falling in one emblazoned sheet, one raging torrent into
the ocean.
The atmosphere in all
directions was filled with ashes, spray, gases, etc., while the burning
lava as it fell into the water was shivered into millions of minute
particles, and being thrown back into the air fell in showers of sand on
all the surrounding country. The coast was extended into the sea for a
quarter of a mile, and a pretty sand beach and a new cape were formed!
Three hills of scoria and sand were also formed in the sea, the lowest
about two hundred and the highest about three hundred feet.
"For three weeks this
terrific river disgorged itself into the sea with little abatement.
Multitudes of fishes were killed, and the waters of the ocean were
heated for twenty miles along the coast. The breadth of the stream where
it fell into the sea, is about half a mile, but inland it varies from
one to four or five miles in width, conforming, like a river, to the
fall of the country over which it flowed. The depth of the stream will
probably vary from ten to two hundred feet, according to the
inequalities of the surface over which it passed. During the flow, night
was converted into day on all eastern Hawaii; the light was visible for
more than one hundred miles at sea; and at the distance of forty miles
fine print could be read at midnight.
"The whole course of the
stream from Kilauea to the sea is about forty miles. The ground over
which it flowed descends at the rate of one hundred feet to the mile.
The crust is now cooled, and may be traversed with care, though scalding
steam, pungent gases and smoke are still emitted in many places. In
pursuing my way for nearly two days over this mighty smouldering mass, I
was more and more impressed at every step with the wonderful scene.
Hills had been melted down like wax; ravines and deep valleys had been
filled; and majestic forests had disappeared like a feather in the
flame. On the outer edge of the lava, where the stream was more shallow
and the heat less vehement, and where of course the liquid mass cooled
soonest, the trees were mowed down like grass before the scythe, and
left charred, crisp, smouldering and only half consumed. There are
numerous vertical holes in the lava, almost as smooth as the calibre of
a cannon, which represent the trunks of trees; they were too green to
burn when the lava flowed around them but succumbed later to subaerial
decay.
"During the progress of
the descending stream, it would often fall into some fissure, and
forcing itself into apertures, and under massive rocks and even hillocks
and extended plots of ground, and lifting them from their ancient beds,
bear them with all their superincumbent mass of soil, trees, etc., on
its viscous and livid bosom, like a raft on the water. When the fused
mass was sluggish, it had a gory appearance like clotted blood, and when
it was active it resembled fresh and clotted blood mingled and thrown
into violent agitation. Sometimes the flowing lava would find a
subterranean gallery diverging at right angles from the main channel,
and pressing into it would flow off unobserved, till meeting with some
obstruction in its dark passage, when, by its expansive force, it would
raise the crust of the earth into a domelike hill of fifteen or twenty
feet in height, and then bursting this shell, pour itself out in a fiery
torrent around. A man who was standing at a considerable distance from
the main stream, and intensely gazing on the absorbing scene before him,
found himself suddenly raised to the height of ten or fifteen feet above
the common level around him, and he had but just time to escape from his
dangerous position, when the earth opened where he had stood, and a
stream of fire gushed out."

Visit of Captain Wilkes
Captain Wilkes of the
United States Exploring Expedition made a prolonged stay at the two
volcanoes in 1840-1. With this greater mountain in sight (Mauna Loa),
Wilkes was quite disappointed when called to look at the uncouth black
pits beneath his feet known as Kilauea. It was nothing but a depression,
insignificant in comparison with the great plains and mountain, and
exhibited scanty signs of fire. There was, however, a small cherry-red
spot in the distance, above which was a cloud of silvery brightness. The
depression itself, when properly examined, proved to be of grand
proportions, three and a half miles long, two and a half wide and nearly
a thousand feet deep; and he says the city of New York might easily be
placed within it and have room to spare. At night the immense pool of
cherry-red lava in a state of violent ebullition illuminates the whole
expanse, flowing in all directions. With him were over two hundred
native Hawaiians crowded upon the brink, gazing upon the scene in
terror, fearing the vengeance of Pele for trespassing upon her domain.
The descent into the pit was by the route used at the present day,
starting at the Volcano House. First was the descent of six hundred and
fifty feet to the platform known as the black ledge. Continuing upon
this shelf for a mile, he stood directly over the lake of fire, three
hundred and fifty feet below, 1,500 feet long and 1,000 feet wide. There
was very little noise, and that was a low murmuring such as is heard in
the boiling of a thick liquid. Occasionally masses of red-hot matter
were ejected to the height of about seventy feet; then falling back. The
lake was apparently rising, needing only a few feet of overflowing its
banks.
The sketch made with the
camera Iucida by Mr. Drayton is reproduced, Plate 28, and is one of the
best ever made of the volcano. It was taken from the north end. The lake
of fire, which we know as Halemaumau, is in the distance. The vapors
nearer arise from cracks in the lava, and consist of steam and
sulphurous gases. The platform which seems perfectly level is the black
ledge, which before the late eruption is supposed to have extended
entirely across the lower pit. The shelf is from six hundred to 2,000
feet in width, seamed by crevices. It is not so smooth as it would
appear, as it is covered by large pieces of lava, and in places rises
into cones thirty or forty feet high. Here and there are huge tortuous
masses stretched lengthwise like hideous fiery serpents with black
vitreous scales.
The lower platform
is like the upper in most respects. It may be covered by a scoriaceous
vitreous layer, which crumbles and cracks under the feet. Small patches
break like glass. The underlying basalt is firm and solid. A third
variety is a black pumice. There are beneath, also, dark pits and
vaulted caverns emitting blasts of heated air at the temperature of
180°. The floor is three hundred and eighty-four feet below the upper
platform.
The lake because of its
intense heat could not be approached nearer than 1,800-2,000 feet. It
was discharging liquid matter at short intervals directly across the
most convenient route of travel. The capillary glass, known as Pele's
hair, abounded in the crevices in loose tufts like tow; and on the
adjacent plain it adhered to bushes. These fibres may be straight with
small drops of glass at one end, or crimped and frizzled, or may be
spread over the ground like cobwebs.
On the return measurements
were made and confirmed of all parts of the volcano, so that the data
were obtained for a map and other illustrations. Dr. G. P. Judd, who had
assisted very materially in managing the natives on the journey between
Hilo and the summit of Mauna Loa, made the attempt to secure samples of
the liquid lava. In pursuance of this quest he was gathering specimens
of the capillary glass on the steep wall of the smaller lake, having
been let down by hand through the assistance of natives. A slight
movement in the lava arrested his attention. In a moment the crust was
broken by a terrific heave and a jet of molten lava fifteen feet in
diameter rose to the height of about forty-five feet with an appalling
noise. In turning to escape he found himself under a projecting ledge
and would have been over whelmed except for the friendly assistance of
Kalumo, a native Hawaiian. Both were badly scorched by the heat. Wilkes
called this pit Judd's Lake, found to be thirty-eight feet deep and two
hundred feet in diameter. It was filled up in twelve minutes.
As an illustration of the
variation of the conditions, upon the night following the narrow escape
of Dr. Judd, the larger lake sank down one hundred feet, thus
discharging a mass of melted rocks measuring fifteen million cubic feet.
The lava ascends from unknown depths, pours over the borders of the
lake, and then there may be a sudden falling away of the liquid because
it has found a way of escape into some cavern or to the exterior of the
mountain low down. These small escapades are the same in principle with
the larger infrequent so-called eruptions.
Plate 29 represents an
attempt to delineate the interior of the volcano at the time of Wilkes'
visit. The data employed are the original maps of the Exploring
Expedition and the later Government Surveys. Professor Dana has
presented the details of the corrections needed by the Wilkes map which
are all incorporated into this plate. It is assumed that there has not
been a sufficient change in the position of the outer walls of the pit
to show in a map of this scale. The black ledge and the pit are
constantly changing. The special features of this map are the less depth
of the walls back of the black ledge as compared with the early
conditions reported by Ellis and Malden, but a greater depth than has
been visible since; and the greater extent of the sulphur bank next to
Keanakakoi. Wilkes' party encamped on the higher ground north of the
volcano. The means are not in hand for a completely satisfactory
representation of this "great lake" to which the name of Halemaumau
belongs. This end of the lower pit is higher than the other.

J.D. Dana's Visit
Mr. Dana was one of the
scientific corps of the Exploring Expedition. It seems very strange that
the geologist of the expedition was not directed to explore the
volcanoes. The commander evidently wished to save that bit of work for
himself; and it must have been a source of satisfaction to Dana that he
was able to correct the errors of Wilkes' map, even though it
necessitated a visit to Kilauea in 1887, forty-six years later. The
official report upon the Geology of the Expedition was published in
1849.
Dana first saw the volcano
in November, 1840, two months before Wilkes went there, and six months
after the eruption. He spent five days in traveling from Kealakekua to
Hilo, two nights and a day at Kilauea. The great lake, 1,500 feet long
and 1,000 wide, was then in full ebullition over its surface, and there
were two smaller lakes. Everything was quiet. "Instead of a sea of
molten lava 'rolling to and fro its fiery surge and flaming billows,'
the only signs of action were in three spots of a blood-red color which
were in feeble but constant agitation, like that of a caldron in
ebullition. Fiery jets were playing over the surface of the three lakes;
but it was merely quiet boiling, for not a whisper was heard from the
depths. And in harmony with the stillness of the scene, white vapors
rose in fleecy wreaths from the pools into a broad canopy of clouds not
unlike the snowy heaps that lie near the horizon on a clear day, though
changing rapidly in shape through constant accessions of cloud material
from below. When on the verge of the lower pit, a half-smothered,
gurgling sound was all that could be heard. Occasionally a report like
musketry came from the depths; then all was still again, except the
stifled mutterings of the boiling lakes."
In the night the surface
sparkled all over with shifting points of dazzling light like a "network
of lightning." The smaller pools on the southeast side tossed up jets
much like the larger, even to the height of forty or fifty feet. Streams
of lava, a day later, boiled over from the lake. Upon the black ledge
there were streams of hardened lava, some twisted into ropy lines or
reaching out in rounded knobs, which testified to the presence of
lava-floods much earlier than the recent eruption. Among the chasms he
heard a few long-continued rumbling sounds, showing that a down plunging
of the walls was still in progress.
The shining, glassy
scoriaceous crust crushed under foot is the scum or frothy part of the
boiling lakes. The Pele's hair was spun from the jets of liquid lava
thrown up by the boiling process. The winds carried away the capillary
threads, the heavy or loaded end going down first. The first view
entertained was that the wind drew out the glassy hairs; but it was
shown later by Dutton that the threads are drawn out earlier. The
projected lava is divided into a succession of clots, the hairs are spun
as the pieces pull apart and the wind later transports them.
Dana at this visit
recognized the growth of cones from the solidification of lava about the
edges of the pools. To the east of the lakes there stood a singular
sphere of lava like a petrified fountain. "A column of hardened lava
drops had been raised on a rudely shaped conical base, having a height
in all of about forty feet. It had been formed over a small vent, out of
which the liquid rock was shot up in driblets and small jets-making one
of the fantastic driblet cones, as the author has since called them
the result of blowing-hole action." These are spiracles as defined by
Scrope.
The surface of the great
lake was bordered by banks fifteen to twenty feet high. Dana got the
impression of a very quiet action. It seemed as if a copious stream came
to the surface for a moment and then flowed on. Combined with this the
natural opposition to the statements of what seemed exaggerated tales of
violence, led him to deny to a large extent the presence of explosive
action. Kilauea was the type of quiet volcanic action. Ex plosive
action pertained to other volcanoes like Vesuvius.
The following is an
abstract of the conclusions reached in the official report. First those
relating to Kilauea.
1. No cinder cones were
present because the jets did not rise high enough to allow the
accumulation of fragments.
2. The action was markedly
quiet. The amount of lava discharged in 1840 was about half of that
thrown out in 1823.
3. The lava finds an exit
through rents in the ledges low down.
4. A pit four hundred to
five hundred feet deep was formed at the time of eruption (in 1832
and 1840).
5. There were three great
eruptions in seventeen years, with intervals of nine years and eight
years.
6. There have been
discharges from the walls of the pit as well as at the bottom. The
pools rise and fall independently of each other.
7. The lavas are
principally glassy scoriae; no true pumice; ferruginous stalactites
formed by the action of steam on the roofs of caves. Minerals are
sulphur, gypsum, iron alum, copper sulphate, sal-ammoniac and gases.
Olivine is frequent and must have come from below in the solid form.
8. There is an unceasing
current to the southwest, a part of a boiling movement. The
temperature of the molten lava probably 1,900 degrees Fah.
9. Kilauea is not a
solfatara, though the sulphur banks (near the Volcano House) may be
so regarded.

General Conclusions Concerning Both
Volcanoes
1. Absence of cinder cones.
2. Eruptions are quiet.
3. Mauna Loa and Kilauea
are isolated; there is no sympathy in their eruptions, so that no
action like that of a syphon can be predicated.
4. The eruptions require
water, which is supplied by the accumulations at the surface.
5. These volcanoes are not
safety valves.
6. The volcanic action is
simply an overflow of a liquid which accumulates till it exerts a
pressure adequate to force discharges through weak walls. It is a
change from a quiet flow to great activity upon the mountain's side.
There is no good evidence to prove that water reaches to the central
fire of the earth's interior.
7. The kinds of crater are
(a) lava cones, (b) cinder scoria cones, (c) tufa cones, (d) pit
craters.
8. Kilauea and ten of the
Mount Loa cones are pit craters, the results of subsidence. The
formation of the pits, or places of ejection of fire, have been from
the northwest to the southeast.
The two kinds of lava were
noticed, the pahoehoe and aa, and the latter were called "clinkers"
which were represented as ordinary lava ceasing to move through cooling,
and then stimulated to activity by a fresh ejection which broke up the
original stream and forced the fragments forwards; compared also to the
breaking up of ice in rivers. The slope of this land from Kilauea to
Nanawale was stated to be I° 28' or one hundred and thirty-five feet to
the mile, and the average slope of Mauna Loa 6° 30.'

The Region of the Discharge of 1840 as
Described by Wilkes
Captain Wilkes went over
the ground traversed by this eruption January 18th to 23d, 184I, and
published a map of the region. He used the name of Lua Pele for Kilauea
iki. A short distance from this he observed a deep crevice about four
feet wide, extending in a southerly direction. At two miles he passed
the pit-crater Kalanokano. This new term he explains as a crater "of
which there is no appearance whatever until one is close upon it, and
which never throws out lava." It might have been formed by the
undermining of the part beneath them, as by a stream of lava, which
running away had left large cavities without any adequate support, and
the superincumbent rock would fall down. Some of these pit-craters are
from eight hundred to 1,000 feet deep. The other craters he describes as
hills of scoria and ashes formed by the ejection of lava, and gives them
the name of cone-crater.
The first cone-crater met
with is about a mile beyond Kalano kano, called Puukehula, about eight
hundred feet high above the plain. From its summit eight pit craters
were visible; four on the Kilauea side, one at the foot of Puukehulu,
and three others to the east-southeast with two cone craters Moka-opuhi
and Kanemuokama. The pit crater Alealea-iki, at the foot of Puukehulu
is about five hundred feet deep, and shows that a stream of lava has
flowed into it. Kanemuokama is the largest of all the pit craters except
Kilauea and an old crater adjacent the most regular of any that the
exploring party had seen upon the island. The new eruptions on both
sides of Moka-opuhi appeared simultaneously upon May 31st.
For several miles the
country consists of rough lava clinkers overgrown with grass and stunted
shrubbery, where walking proved to be irksome and dangerous. About
thirteen miles southeast from the new opening is the cone-crater of
Kalalua of the altitude of 1,100 feet above the plain. It has sent forth
streams of pahoehoe. At the altitude of 1,244 feet, twenty-seven miles
from Kilauea, twenty-one from the first outbreak and twelve from the
seashore at Nanawale, is situated the commencement of the final
outbreak. It began in a point, gradually enlarging, and in two miles
became a torrent of fluid rock from ten to fifteen feet thick, sweeping
everything before it. The fallen timber still remained, only holes were
left to show where it once stood, the stumps having been entirely
consumed, sometimes reaching a depth of twelve to fifteen feet. In some
places lava was found adhering to the leaves and branches of trees. A
copse of bam boo remained in the midst of the flow, and many of the
trees were still living. Some large trees not more than twenty feet from
the stream were scarcely affected, while it was still possible to light
walking sticks two feet below the surface and only thirty yards from
these living trees. This was eight months after the eruption. Nearer the
sea all the foliage to the distance of three hundred and fifty yards
from the lava stream was killed. The slope of this stream was about one
hundred feet to the mile, and its velocity was estimated to be about
four hundred feet an hour.
Wilkes observed many
fissures along the whole line and thinks that lava must have flowed from
them, as lava seems to have issued from them in some cases. Where the
ground was steep, underground tunnels were apparent. The upper part of
the stream consisted of pahoehoe, and much of the lower part, while
somewhat suggestive of clinkers (aa), was to be compared with the slabs
of ice in rivers when broken up by the force of the current. About six
miles from the sea there seems to have been a simultaneous outbreak over
a large area. Occasionally a "blowing cone" was seen with quantities of
salts, sulphur and hot gases still issuing from it.
At the sea the lava fell
over a cliff into the water for a width of three-quarters of a mile.
There were three sand hills, evidently accumulated from a shower of
shivered particles of lava that prevailed while the fiery cataract
existed. They were one hundred and fifty and two hundred and fifty feet
high when Wilkes saw them. Brigham says they were not a third as high in
1864. And in 1883 and 1899 when seen by myself, they were still smaller,
because of the action of the sea. The sand originally extended about one
hundred feet into the ocean. There is more olivine in this sand than is
common in the lava; due probably to its higher specific gravity.
Wilkes' figure of these
sand hills represents a fissure between them, but his mention of the
sand storm would seem to imply an eolian origin. Dana's figure made in
November, 1840, does not indicate any fissure, but in his text he calls
them examples of elevations thrown up suddenly over fissures of
eruption. "They consist of a rusty yellow tufa, distinctly and finely
laminated." Had he not adhered to this theoretical statement down to his
latest publication, it would seem as if he had himself shown the way to
a better view, for he says: "The sands are said to have been thrown out
from the center of each hill while in progress; yet there was no cavity
at top. As the molten lava met the sea there was a violent explosion and
an ejection of fragments which fell around the center of eruption; and
owing to the water which ascended and descended with them, the structure
became laminated." The stratification is concentric: hence the layers
were entirely of eolian origin. It is easy to contrast the structures of
these sand hills with tuff cones formed near the seashore in the normal
eruptive way. These always show a hollow interior. I have found these
peculiar sand hills on the edge of the sea in other parts of Hawaii and
Maui and believe them all to have had an eolian origin.

Kilauea between 1841 and 1849
In the interval between
the discharges of 1840 and 1849 two novel features are developed. The
first relates to the production of a central lava lake resting in a
basin of its own cooled material. The second is concerned with the
encirclement of Halemaumau by an igneous canal, coinciding nearly with
the edge of the next black ledge to be formed.
In February, 1842, Mr.
Coan writes: "When within four or five rods of the great lake, unaware
of our near proximity to it, we saw directly before us a vast area of
what we had supposed to be solid lava moving off to the right and left.
We were at first a little startled, not knowing but all was about to
float away beneath us, especially as the lavas for a mile back were
almost insupportably hot, and gases and steam were escaping from
numerous openings. On looking again, we perceived that the whole surface
of the lake was from six to fifteen feet above the level of the
surrounding lava, although at my last visit it was from sixty to seventy
feet below. Within six feet of this embankment we could see nothing of
the lake, and in order to examine it we climbed the precipice some fifty
feet. The explanation of this strange condition of things is this: when
the liquid contents of the lake had risen to a level with the brim there
was a constant and gradual boiling over of the viscid mass, but in
quantities too small to run off far. Consequently it solidified on the
margin, and thus formed the high rim which confined the lavas. Twice, or
at two points while we were there, the liquid flood broke through the
rim and flowed off in a broad, deep channel which continued its flow
until we left the volcano. The view was a new one, and thrilling beyond
description."
In July, 1844, Mr. Coan
describes a vast overflow at Halemaumau, from which rivers of lava
proceeded adjacent to the black ledge on either side. The beginning of
the process consisted in the welling from below of so much liquid that
the outlines of Halemaumau were obliterated. The streams were described
as two deep canals five to fifteen rods wide, one hundred feet deep and
two miles long; it was a lake having two outlets at its opposite points,
each one following the margin of the black ledge and coming within half
a mile of each other under the northern wall of the caldera.
Mr. Coan had the company
of his son, Titus Munson Coan, who noted the conditions already
mentioned, and spoke also of a small lake upon the floor of the pit at
about the middle of the west side. A diagram accompanied Mr. Coan's
letter, a mere outline, but having all the essential features indicated
two years later by Mr. Lyman.
There were fissures along
the course of the canals, one of them two hundred feet deep, and in one
place the lava plunged down a precipice of fifty feet. The character of
this display was not explained at the time. In June, 1846, Mr. Coan
reported that the central parts of the floor had been elevated four or
five hundred feet since 1840, so that some portions of it are higher
than the black ledge. Professor Dana thinks from this statement that in
1844 the lower floor was less than one hundred and forty feet deep,
except along the wide canals.
The observations of Rev.
C. S. Lyman in July, 1846, explain the rapid obliteration of the lower
pit. See our Plate 30 restoring the condition of the caldera after the
rude sketch of Mr. Lyman. He found the conditions reported by Mr. Coan.
By instrumental measurements he proved that the black ledge still
retained the level of six hundred and fifty feet below Uwekahuna as
given by Wilkes. But there was a "canal nearly up to the black ledge,
and in some places quite," encircling the pit, though in some parts
obliterated. Along the inner margin of a part of the canal was a
continuous ridge of angular blocks of compact lava often fifty or one
hundred feet high, which Mr. Lyman considered "once constituted a talus,
or accumulation of debris" on the slope of the black ledge of 1840; the
floor with this margin of blocks had been elevated till this ridge
overtopped the edge of the escarpement at whose incline it had been
accumulated.
He adds: "The phenomenon
seems inexplicable on any other hypothesis than that of the bodily
upheaving of the inner floor of the crater."
"When visited by the
Exploring Expedition of 1840, the surface of the Great Lake was between
three hundred and four hundred feet below the black ledge, and measured
only a thousand by fifteen hundred feet in diameter. Consequently in six
years the lake had not only increased in size, but it had actually risen
in height as much as it had been previously depressed by the
out-draining of lavas in the eruption of 1840. This gradual rising of
the solid embankment of the lake contemporaneously with the lake itself,
together with the filling up of the whole interior of the crater, is
doubtless to be attributed to the combined effect of repeated
overflowing together with the upheaving agency of subterranean forces."
The lake at the southern end seems to have been raised upon a rim ten to
twenty feet high, with the diameters of 2,000 and 2,400 feet. The lavas
were in gentle ebullition, tossing up broken jets five to fifteen feet
and frequently encrusted, and had a general movement southwesterly.
Sticks of wood thrown into the liquid immediately disappeared, but were
instantly followed by a sudden outburst of flame and smoke.
The "Furnace" marked on
the map was the beginning of a dome, ten or twelve feet high with walls
a foot thick, compared by a later writer to pie-crust; inactive in July
but "in full blast" six weeks later in August. Brigham compares this to
one of the "hornitos" described by Humboldt in the malpays of Jorullo,
Mexico.
On December 7th, Mr. Coan
found the lake full and active. On July, 1847, the great lake had filled
up and overflowed a considerable area around its rim, and it was easy to
dip up the viscid matter with sticks and ladles. Early in 1848 a thick
crust formed over Halemaumau and was raised into a dome covering the
whole lake. This increased in size and by August was almost high enough
"to overtop the lower part of the outer wall of Kilauea and look out
upon the surrounding country." This meant two hundred or three hundred
feet elevation, traversed here and there by fissures through which it
was possible to descry the glowing of the subterranean fires.
Occasionally lava was pressed sluggishly through these apertures,
rolling in heavy and irregular streams down the sides, spreading and
cooling over the slopes or at the base. Thus this dome has been formed
partly by upheaval and partly by igneous accretion. This is the first
account of a dome over Halemaumau.
Still later in the autumn
of 1848 an extraordinary inactivity prevailed throughout the crater. No
fire was visible, even in the night.
Back to Contents
Eruption of 1849
This eruption was not very
important. In April and May explosions and detonations from the cones of
the great dome startled travelers. They were compared to the discharge
of whole ranks of musketeers or field artillery. They were repeated
hourly and attended by a brilliant column of red-hot lava, rising fifty
or sixty feet above the dome. "At other times red-hot stones were
projected with great force into the air and sent whizzing like fiery
meteors through the gloom of night." Later a stream of lava came from
the ridge of the dome, flowed to the base and wound along the floor like
a fiery serpent. These phenomena are what precede an eruption; and as
they ceased shortly afterwards, it is presumed that the lavas escaped
into some subterranean cavity, and the fires went out.
During the two years 1850
and 1851 there was very little indication of heat. Mr. Coan
characterizes it as a time of "steaming stupefaction." In March, 1852,
he says the great dome a mile and a half in circuit and several hundred
feet high has lost its keystone and the opening is one hundred feet in
diameter, increasing to two hundred in July. The lake is gradually
rising and threatening to engulf the whole overhanging mass; but in the
latter part of 1853 it still remained, two miles in circuit and from
three hundred to six hundred feet high. The central lower plat form
rose during this year above the black ledge, some points of it being six
hundred feet higher than after the eruption of 1840, and in some
portions zoo feet above the black ledge. Lyman's ridge of blocks
retained its position little changed.
The crater was "unusually
dull" all through 1854. Ferns and ohelo bushes grew upon the lower
platform.
Back to Contents
Eruption of 1855
In May and June travelers
reported a fiery girdle around the whole circumference of the caldera;
intense heat and suffocating gases were encountered upon the road back
of Uwekahuna, so that men and horses were forced to make a wide detour
to the west. The fires evidently followed the course of the canals
reported in 1846; and along these lines Mr. Coan could count sixty areas
of fusion or "lakes of leaping lavas." One great lake was located at the
foot of the path down the sloping terraces, and there were other boiling
caldrons so that the continuity of the road to Halemaumau was
interrupted.
On July 6th
Mr. T. M. Coan found the
lava lake in the path mostly covered by a crust, but the lavas were in
violent action in several places along the margin of the black ledge.
Halemaumau was estimated to be two hundred and fifty to four hundred
feet in diameter surrounded by walls seventy-five feet high. The surface
became encrusted, but every five minutes there opened in the center a
fiery surface perhaps fifteen feet across from which a fountain would
burst out up to twenty-five or thirty feet. In the vicinity another
similar fountain in a few seconds would start up and go through the same
changes. There were furious surgings and outflows of lava from cavernous
openings under the northeast wall. Much Pele's hair was found and there
were two islands in the northwest part of the lake.
Sept. 8, 1855
Lake two or three miles in
circumference, circular. Several comes emitting smoke, from some of
which issued streams of lava. "One stream was not less than seventy-five
or one hundred feet wide, descending at an angle of near 45° and
branching off in two opposite directions. Two of these cones presented
the appearance of immense furnaces." At night there was the great light
of the lake and some twenty lesser lights visible. Editorial by S. C.
Damon in the Friend.
October 9th
there was less activity
and the dome had fallen in. There had been a dozen open lakes arranged
in two semicircular lines from Halemaumau along the eastern and western
sides, probably on the border of the lower platform of the previous
years. The flow is very distinct northwards. The encircling belt has
been elevated between one hundred and two hundred feet since April.
Though meager these
accounts are believed to describe the important breakdown of 1855,
coinciding essentially with the great eruption from a vent high up upon
Mauna Loa. It is confirmed by the estimate of the height of Uwekahuna
given by Mr. Weld in the following month.
Mr. F. G. Weld visited
Kilauea November 14th, 1855, on the way to the flow of 1855, Mauna Loa.
It was not a time of activity. No lake of fire could be seen, although
the light of subterranean fires was obvious at night. His companion, Mr.
Stuart Wortley, observed that hot stones and melted lava were
occasionally ejected from small craters. And Mr. Weld on his return from
Mauna Loa spoke of the floor as being evidently the cooled upper crust
of fused lava. The small mounds have orifices like the mouth of a lime
kiln through which one can look into the red-hot depths below. In some
places there were long ridges of smoking rock fragments that had been
piled confusedly upon one another. Heat and noxious gases were exhaled
from various vents. The lava was generally of a dull, glossy lead color
when cool; but of a brighter green or blue when more recent. The "Pele's
hair" had reddish, brownish and golden hues. These gentlemen lodged in a
grass hut. The height of the highest cliffs from the bottom of the pit
has been estimated to be 1,500 feet, and in many places they were
satisfied it was considerably less. Other familiar objects were seen by
these visitors. From Quarterly Journal of Geological Society of
London, Vol. 13.

Between 1855 and 1868
In March and October,
1856, there was some sluggish lava in Halemaumau and hundreds of steam
jets. The inner platform of hardened lavas keeps its elevation of about
six hundred feet above its level of 1840.
J. H. Wood in 1892 says
that in 1856 the crater floor was several hundred feet deeper than at
the time of writing. There were cones, chimneys and blow holes, and a
ridge of rocks entirely gone later. The caldron was surrounded by a rim
thirty feet above the crater floor and fifty feet above the lake, where
the lava was surging, spouting and tossing masses from minute particles
to tons in weight.
In June, 1857
Halemaumau was a lake of
five hundred feet diameter surrounded by ragged walls a hundred feet
high. Every three minutes a crust would form and then be broken up.
There was little change in
the conditions during 1858. In August the great lake had the same size
as in 1857 and there was a constant freezing of a crust alternating with
fractures and melting.
In 1859 Kilauea was
comparatively quiet, showing no sympathy with the great outpouring upon
Mauna Loa. For several years about the same story of the comparative
quiet of the central lake, the constancy of the lower platform and
occasional small displays of fire is told.
Halemaumau was a lake
about six hundred feet in diameter. Without it, in the basin, there was
a driblet mound with pinnacles and turrets. In 1863 a large fountain
played at the middle of the lake at intervals from a few seconds to half
a minute, throwing up crusts of lava ten or twelve feet high, and
smaller portions twenty or thirty feet high. Elsewhere it was covered by
a thin crust easily ruptured by small stones thrown upon it. In October,
1863, the great lake and the black ledge were covered by fresh lavas,
while the central tableland five or six hundred feet above the floor of
1840 showed no change.
In 1864
Mr. W. T. Brigham
commenced his examination of the volcano and its surrounding. With
instruments he made an accurate map which has been the basis of every
plan published since that time. This is reproduced, as modified by
Captain Dutton, in Plate 31; and from it one can learn the conditions
prevalent in 1864 and 1865 and note the changes from the features
described by his predecessors. Professor Dana comments freely upon these
data in his book.
Some of the dimensions as
measured upon this map are as follows: The main caldera is nearly three
miles long; the greatest width nearly two and one-quarter miles; extreme
length of the depression from north of the sulphur bank to extreme south
end three and three-quarter miles; upper triangular platform near the
house nearly one mile long; circumference of the main pit eight and
one-half miles. The bottom of the pit is stated to be "more than four
hundred feet." The observations relate to 1864, 1865, and the map
surveys were made in 1865, between August 20 and 24.
The following features are
distinctive: The floor is essentially upon the same level, the lower pit
having been nearly obliterated by the lava overflows. The position of
the margin of the black ledge is indicated by the "high rock" and
"ancient lava," obviously identical with Lyman's ridge of loose blocks;
by the two small lava lakes near the northwest corner, two patches of
lava farther south and the active cones, one on each side of the pit. A
painting by Mr. Perry in 1865, as photographed by Brigham, shows the
position of the black ledge very plainly, in the slight shading; but the
whole bottom was regarded as the black ledge. The sulphur banks on the
southeast side of the pit are smaller than ever before. Halemaumau has
its old position, and had a diameter of eight hundred feet in 1864 and
1,000 in August, 1865. It was surrounded by walls fifty feet high in
1864 and thirty feet high in 1865. Judging from the illustrations the
surface of the molten Java was considerably agitated. Occasionally the
liquid rose suddenly several feet and was "boiling- violently and
dashing against the sides, throwing the red-hot spray high over the
banks." "There was no noise except the dash and sullen roar." The two
small islands present in 1864 had disappeared in 1865.
Other interesting features
were the "Cathedral," a driblet cone with several turrets of varying
altitude, mentioned first by Mr. Coan in 1862; several caves, exhibiting
the singular stalactitic tubes, and stalagmites; fissures or cracks near
the northern sulphur banks, Waldron's ledge, near Keanakakoi and by
Uwekahuna, all concentric with the wall of this pit; and finally one
nearly a mile long rudely concentric with Halemaumau. This possibly
corresponded to the border of the columnar mass outlining the elevations
in 1888 and 1892. Halemaumau was eight hundred feet long in 1864 and
1,000 in August, 1865. The encircling banks varied from fifty to thirty
feet in height. The liquid was usually quiescent though occasionally in
violent ebullition and throwing the spray over the bank. The small
island visible in r864 had disappeared in the following year. Distinct
flames of fire were also observed. "They burst from the surface and were
in tongues or wide sheets a foot long and of a bluish color, quite
distinct from the lava even when white-hot; they played over the whole
surface at intervals, and I thought they were more frequent after one of
the periodical risings of the surface in the pit."
In 1865
Rev. O. H. Gulick
presented to the landlord of the grass house which had been built for
the convenience of visitors, a record book in which notes might be
written descriptive of the conditions at the volcano. I have been able
to examine all the records from this early date through the whole
intervening period to the end of 1908; and will quote freely from them.
Mention was made by Mr. Gulick of the formation of a great crack on the
side of Uwekahuna from three to eight feet wide in September, 1863,
following an eruption in May or June which flowed over an area of one
thousand acres, and another smaller lake was formed near the north wall.
There were several of these active vents in that part of the pit
specially mentioned as existing in 1864 and1865.
June 4, 1865
D. H. Hitchcock made his
nineteenth visit to Kilauea and observed a lake on the north side three
hundred feet long adjacent to a spiteful chimney. The older lake had
been extended to the northward and lava flowed from the new lake for a
mile.
June 27
C. Arnold found the lake
unusually active.
In May, June and July,
1866, Mr. Coan describes a great increase in activity. New lakes and new
cones opened along a curve northwest to north of Halemaumau, flooding
all that portion of the caldera and reaching to the sulphur banks. The
area covered was two miles long, and half a mile wide, and the usual
entrance to the lake was cut off. Mr. Sessan estimated the size of the
north lake as two hundred by five hundred feet. There were seven lakes
between this and Halemaumau and they increased in size till the eruption
of 1868. This flooded region was said by Brigham to be about fifty feet
below the central area; it was a hundred feet higher than in 1865; but
the central area has also risen so that the relative height was about
the same. The general appearance of Kilauea had changed. The ledge of
broken blocks near the margin of the earlier black ledge has nearly
disappeared because it has been covered by the recent outflows, and the
various caves have been obliterated. Large blocks of basalt have fallen
from the steep outside walls, which were speedily absorbed by the molten
flood, illustrating the method by which pit craters may be enlarged
horizontally. Travelers during this summer spoke of the hissings,
spoutings, rumblings and detonations as terrific. In August the activity
ceased, but no subterranean discharge was noted; the central plateau
remained undisturbed and hence it is not certain that an eruption took
place; though the phenomena would seem to indicate a considerable
disturbance.
August 6, 1866
Dr. G. P. Judd writes: "I
first visited this crater in 1830 when its depth was three or four times
greater than now. In 1849 I marked a spot upon the bank estimated at
sixty feet above the bottom which is now out of sight." Oct. 23 he adds:
"Since August 6 the long ridge of rocks and earth which had fallen from
the western wall and appeared to be floating into the middle of the
crater bottom, has floated past the middle to the eastward. The center
is rising slowly without change of surface, while the sides of the whole
crater have been overflowed and kept full of fresh lava. The action at
the south lake is grand. There are several new lakes."
George Clark, July 20 to
25, 1867, says that on May 23, 1864, there was but one lake and that not
large. At a later visit he saw a large island melt away. On the 19th
inst. he first saw the large north lake, with several others. A
blow-hole near the south lake had diminished in importance. Very much
new lava had been flowing. The cones seen in 1864 are filled up.
Sept. 18, 1869
A. Francis Judd wrote that
he first visited Kilauea in 1853. The bed has since greatly filled up
and the south lake has many rivals, eight of them being now in sight.
The same day La Paz says:
"Kilauea is not a crater but a deep chasm formed by the breaking of the
rocks about a thousand feet below the level of the surrounding country.
There never was a lava flow from Kilauea." His conclusions were based
upon a comparison of Kilauea with various volcanoes in Central America.
The northern lake was first formed in March, 1867, and had been
enlarging ever since.
Back to Contents
Kilauea in 1868
The disturbances occurring
this year have been to some extent confused with those emanating from
the greater neighbor on the north. It was the time of the most extensive
earthquakes known in the history of the islands and it has not been
absolutely demonstrated whether Kilauea was or was not concerned with
them.
Dr. Hillebrand obtained
information from Judge Kaina, an intelligent Hawaiian who resided near
Kilauea during the times of disturbance. He and a Chinaman were the only
persons at Kilauea at that time. From January 20th to March 27th the
crater had been unusually active: there were eight lively lakes,
frequently overflowing. There was a large blow hole to the northwest of
the lakes which at regular intervals of a minute or less threw off large
masses of vapor comparable to the discharge of steam from a locomotive.
This ceased about March 17th, and the lakes became more active. March
27th the first earthquake shock was noted. March 29th Mr. Fornander
found fresh incandescent lava in the bottom of the crater. April 2nd, a
little after 4 P.M., the great shock occurred and great commotions
throughout the districts of Hilo, Puna and Kau ensued: the ground swayed
back and forth, large quantities of lava were thrown to great heights;
portions of the walls of Kilauea fell in and there were fearful
detonations. These continued for more than three days. "From the very
first the fire began to recede." The first night it was confined to the
lakes; the third night it appeared only in the south lake; and
twenty-four hours later it had entirely disappeared. Two days still
later came the first outburst of Kahuku. April 2nd Kilauea iki was
overflowed by a black shiny lava, which adhered to the trees and shrubs
in the upper part of its course as shown in Plate 23.
Dr. Hillebrand visited the
locality where the lava from Kilauea came to the surface, April 2oth.
Near the fork where the road turns to Puna instead of continuing on to
Kilauea (Halfway House), heavy clouds of white vapor were seen to rise
on the lower side of the road. Half an hour's ride brought the party to
deep crevasses in the pahoehoe--the longest one twenty-four feet wide
with no bottom visible. It was followed for four hundred feet, but with
less width, never less than eight feet. In a belt about six hundred feet
wide parallel with the first were a number of smaller fissures. From
many of these openings hot steam issued. Fire was not visible, but it
would appear by reflection at night and was probably the cause of the
supposed fire seen for several days.
Judge Kaina is quoted in
the Record Book as saying that by April 5 the fire disappeared and was
not seen again till May 27. Since then the depression has been filling
up.
July 26
W. D. Alexander says: "No
material change has taken place since the visit of Dr. Hillebrand, April
18. Nearly the whole of the pit in the southwest end of the crater is in
a state of fusion. It is nearly divided in two by a ridge of rocks. The
farther one of the two has about the same position as the old South
lake. Nine caves, five on the south and four on the north side were
spouting fiercely, while at the eastern end a small lake spouted thirty
or forty feet high, forming a large cone out of the falling fragments.
About the center of the farther lake lava was flowing in a southeast
direction. Streams from the cones took the same direction. The eastern
boundary of the pit seems to coincide with a great crack formerly
existing and delineated upon Mr. Brigham's map. The display of fireworks
tonight was magnificent and shows increasing activity.
Aug. 5
the South Lake was the
center of operation.
Aug. 7 W. W. Hall says:
"There was very little action but there were eight or nine blowholes
making a great noise, and fire was visible in some of them. The activity
was less than in July."
Sept. 5
C. E. Stackpole says:
"There were twelve lakes in active operation just before April 2. Nearly
the whole of the north part of this pit was thus covered with liquid
lava. For two weeks after the earthquake there was no fire, but it has
now returned."
Mr. Coan was quite
successful in his search for a discharge of the lava in August. After
passing several smoking fissures he turned to the left, towards the sea,
and after an hour's hard search among rough hills discovered five
different points on a line of less than a mile in length where fused
lavas had been thrown out. The largest patch was 1,000 feet long and six
hundred wide, with an average depth of ten feet, upon whose surface
tumulated eminences were still steaming, and is represented upon Plate
26, near the Halfway House. This locality is about eleven miles S. W.
from Kilauea. The facts discovered by Mr. Coan and their connection with
Kilauea are acceptable; but his theoretical view that these lavas
continued underground to connect with the discharge at Kahuku is open to
serious objections.
Mr. E. D. Baldwin has
investigated the country to the south of the Halfway House, and has
kindly furnished the following statement: The reader will note that
there is a series of cracks to the south of the Half-way House from
which the considerable area of lava southwest from the 1823 flow exuded.
This was not seen by Mr. Coan. The area as figured may include a little
more lava than belongs to it. The eastern finger-like protuberance must
have been part of an older flow: but the flow is believed to have
included most of the area marked '68 crack.

Letter from E. D. Baldwin
I believe you asked about
the flow from the 1868 crack! Would say that in my survey, we camped
about two weeks, a mile below where the main flow left the crack; our
camp being located mauka of Puu Nahaha, an old fault line, just two
miles opposite the Kapapala Ranch houses. Just back of the Halfway
House, the lava made two large spurts ; the upper one welling up through
the crack and covering probably three acres; about one-half mile below
this, the lava spurted up through the crack and ran for several hundred
feet, then it seems to have run under ground, until it reached the point
mentioned above, about a mile above our camp, where the whole appearance
of the flow, is that of a sudden opening of the crack along its whole
line, and the lava flowing out in a great belch, twenty or thirty feet
high, and rushing towards the sea, mostly along the line of the crack. A
portion of the flow turned off towards the 1823 flow, striking several
old red cones, in its path, and completely plastering the upper side of
these cones with new black lava. One old red cone especially was very
noticeable, it stood right in the line of the rush of the lava, which
struck the upper side, and poured over the upper rim and through the old
crater in the same, leaving the lower side of this cone untouched; as
the high rush of lava passed on, it subsided leaving this cone standing
at least thirty feet high, with its upper side completely plastered with
a layer from one inch to a few inches in thickness, and at the foot of
all of the cones, immense grooves in the new lava show the force of the
rush of lava as it subsided. I climbed to the top of the cone, and it
seemed fully forty feet high on its upper side and highest part where
the lava had just reached and splashed over; on both sides of this
highest point, the lava had rushed over and through the crater, breaking
away its lowest wall on the southwest side. I made several trips to
where the main flow first left the crack, and there is no question
whatever about its coming from the crack at the time it opened in 1868,
as just above this point is an old red aa flow, and all the lava around
is the same. Also from this point and all along the crack for miles down
the lava spurted into the air, leaving many lava spatters, sometimes
several hundred feet from the crack, looking more like our old mud pies,
we used to make when boys. These lava spatters are of the same age and
nature as the flow; also the flow can be traced all along, in many
places, running back into the crack. The depth of the flow is on an
average of one and one-half feet, and in many places looks like paving
it is so smooth. Where the flow struck the forest in its line, it is
full of tree moulds, many of which stand several feet high; and were so
suddenly formed that they are all capped over with lava on top.
Judge F. S. Lyman of Hilo,
was living at Kau, between the Pahala Mill and the 1868 mud flow, at the
time of the great 1868 earthquake, and states that all he remembers, is
that they saw a great many lights in this direction, the night after the
great earthquake, but so upset and taken up were they by the terrific
shaking they got, and subsequent Kahuku flow, from Mauna Loa, that no
one paid any attention further to the region of the great crack. My
opinion is that the flow from the r868 crack was of only a few hours
duration, also the whole line of this flow is completely hidden from the
Kapapala Ranch houses, as well as from Pahala, by the Puu Nahaha fault
line, and Puu Ula hills, also intervening forest, so that the lights
seen by Mr. Lyman, must have been reflections from the glow holes along
the line of flow.

The Changes in the Pit
Returning to Kilauea, Dr.
Hillebrand states that on the 18th and 19th of April, the crater was
entirely devoid of liquid lava. Large segments of the walls had fallen
in on the west and eastern sides. The heat was considerable in the pit
of Halemaumau, too great for the hand to bear. This pit was more than
five hundred feet deep. More than two-thirds of the old floor of Kilauea
has caved in and sunk from one hundred to three hundred feet below the
level of the remaining floor, the submergence having been most prominent
in the western half. There was a depression from Halemaumau
northwesterly, when a cliff three hundred feet high loomed through the
mist. Surmounting this, Dr. Hillebrand found himself at the brink of a
fearful chasm several hundred feet deep, and about half a mile long from
south to north. Very hot air rose from it. Changes in the floor were
taking place constantly.
Mr. Coan thus describes
the same area as seen in August:
"The central area of the
great crater had subsided about three hundred feet, forming a new 'Black
Ledge' of unequal width all around the crater. In some parts the central
depression left the ledge a perpendicular or beetling wall with a
serrated line, but in most parts the center sagged away gently, forming
a large concave basin with an angle of twenty to seventy degrees. The
surface of this concave was once the crowning or convex portion of the
crater, where ferns and ohelo bushes had been growing for nearly twenty
years. The superincumbent plateau has been depressed so quietly that the
surface is very little disturbed, and the ferns and ohelo bushes are
still growing in the basin three hundred feet below their position on
the first of April. Some parts, however, of this great area have been
covered with fresh lava, and some ferns have been killed by heat and
gases.
"From the Black Ledge I
passed down and across this depression (about a mile) and then up the
ascent on the other side for half a mile to the rim of Halemaumau. This
is all changed; it has gone down some five hundred feet below the
highest point on the Black Ledge, and about two hundred feet below the
depression in the basin above mentioned. The walls have fallen on all
sides, and the pit resembles a vast funnel, half a mile in diameter at
the top and about 1,500 feet across the bottom. There are two places
where visitors can descend into this great pit, with some difficulty and
risk. Much of the time, this pit is filled with smoke and sulphurous
gases, with little visible fire; occasionally, however, detonations and
fiery demonstrations occur in this awful pit."
By comparing maps and
notes it is possible to outline the area and dimensions of the lower pit
created by the breakdown of April 2-5. More than two-thirds of the floor
had collapsed, coinciding approximately with the canals of Lyman, the
ridges of Brigham, and later with the depression mapped by Lydgate in
1874, an area of 8,000 feet long, 6,000 feet wide in the northeastern
portion, narrowing to 1,000 feet at Halemaumau. The depth was greatest
at the southern end, six hundred feet, half as much in the middle with
sloping walls. The comparison of the basin to a heavy pie crust, "fallen
in at the middle, leaving a part of the circumference bent down but
clinging at the outside of the dish," well describes its appearance.
Compared with the breakdown of 1840 it will be seen that the lava
removed must have been about the same. The black ledge had increased
somewhat in altitude between the two dates, at least fifty, perhaps one
hundred, feet. The task now set before the volcano for the next eighteen
years, 1868-1886, is first to rebuild the mound of Halemaumau to a level
with the black ledge, and then the filling of the basin so as to cover
the entire floor.
It is stated by Mr.
Nordhoff that just before the earthquake of April 2nd, streams of lava
oozed out through the crevices in the depressed area between Kilauea and
Kilauea iki. The evidence of a lava flow is afforded by the adherence of
lava to the trees, perhaps fifteen feet above the original surface.
These were visible in 1886, and a photographic representation of the
trees thus encrusted is presented in Plate 32. These incrustations may
have been only a few clots thrown out from the opening.
The line of the fissure
near Kilauea iki runs N. 60 degrees W. by compass in 1905. Between one
and two hundred feet above the floor is a wide fissure lined with
clinker or scoria, very fresh, of both bright red and black colors, the
same material constituting the driblet cones. From this fissure there
was a discharge of a considerable stream of ordinary aa and pahoehoe
down to the lowest level through the forest. It is easy to distinguish
between the flows of 1832 and 1868 by the presence of some vegetation on
the earlier discharge. The specimens of clinkers are very much like
those seen in the rent at Kahuku which came out at the same time, except
that the latter contain a considerable green olivine.

Kilauea from 1868 to 1879
After the great
disturbance of 1868, the volcano seemed to take a rest.
Nov. 6, 1868. D. H.
Hitchcock wrote that a chain of lakes had formed around the pit. Since
the earthquake the whole central part had sunken three hundred feet. The
greater part of Halemaumau had fallen into the South lake, which is more
than five times larger than in December, 1867. The high ridge of rocks
has disappeared. The fire is entirely confined to the South Lake. The
center of the pit is now lower than the South lake, and will evidently
receive the lavas flowing from the higher level. The great chasm about
the border was not found till several days after the earthquake. For
three weeks the action at the South Lake has been increasing. It was two
hundred and fifty feet deep at first, and is now only one hundred feet
deep and it continued to fill for three weeks longer (Nov. 26). Four
earthquake shocks were also noted at this time.
In July, 1869, Mr. Coan
states that the great lake was so cool on the surface that he was able
to measure its dimensions without difficulty. It was five-sixths of a
mile wide at the bottom four hundred feet below the rim, and more than a
mile in length from north to south at the top. The lava was still molten
fifty to one hundred feet below the surface, as seen in deep fissures.
Sept. 8, 1869 Prof. J.
D. Butler saw nine cones in the south lake.
Sept. 13 George Jones of
Kahuku spoke of lava flowing from these cones. There were two earthquake
shocks on the 13th and five the next day.
Nov. 9 Kilauea was
visited by H. Bingham 2d. He mentions the South lake, North lake and a
third in the southeast section of the pit. There was no visible flowing
lava, but stones thrown into the chasms from seventy-five to one hundred
feet down splashed into a liquid mass.
Jan. 10, 1870 D. H.
Hitchcock reports the South Lake nearly solid with a little fire. The
center of the pit seems to be sinking, and is below the level of the
South Lake. Pele has not yet recovered from the effects of the agitation
of 1868.
Feb. 2 Kilauea very
active; several lakes opened. Mrs. S. J. Lyman.
Judge Kaina is quoted as
saying that the south lake overflowed on Feb. 19, 1870, for the first
time since 1868, and ran mauka for fifty feet.
March 6 the flow was
rather quiet.
March 28 South lake
filled up. It is one level mass beneath which fire is visible.
April 26-28 D. H.
Hitchcock reports the filling up of South Lake, around which a mound is
forming. Lava is flowing into the deep basin northward.
June 4 Crater quite
lively. Ten cones in action.
July 22 Fresh lava from
which impressions of coins were obtained.
Aug. 22 Crater rather
inactive. J. H. Coney.
Oct. 5 Noise like report
of cannon. One lake formed where there had been three. Of these the
South lake was the largest. Severe earthquake coincident. There was
boiling and surging for five minutes after which quietness ensued. Lakes
not well shown because they were so low down.
March 20-29, I871 Dense
clouds; no fire except deep down in crevices.
April I3 Halemaumau
being built up, forming a dome as in I857. General level of South lake
about up to that of the main crater. Little fire but dense smoke. D. H.
Hitchcock.
July 6 Nothing but smoke
to be seen. E. Bailey.
Sept. 13 No fire. Miss
M. A. Chamberlain.
In 1871, Mr. Coan says
there had been discharges that filled the central basin to the depth of
fifty feet and also flowed two miles northerly since his report of 1869.
In August Halemaumau had
again become empty, but a year later it was full again and discharged
into the basin of 1868.
Jan. 11, 1872 D. H.
Hitchcock says that the main pit has been overflowed from the South
lake, a descent of two hundred and fifty feet. There are three larger
cones in this lake, which are about seventy-five feet lower than the
summit of Halemaumau. There are deep pits with these lakes. Fire is
being concentrated in the vicinity of where the South lake has been.
March 1, 1872 Kilauea
visited by Clarence King and A. Hague. King says: "A fluid stream of
basalt overflowed from the molten lake at the south end of the crater
and flowed northward along the level basaltic floor of the pit. Numerous
little branchlets spurted from the sides of the flow and then congealed.
I repeatedly broke these small branch streams and examined their
section. In every case the bottom of the flow was thickly crowded with
triclinic feldspars and augites; while the whole upper flow was nearly
pure isotropic and acid glass." Charles Darwin had previously made a
similar statement about the development of minerals in the lower
portions of volcanic flows.
March 20 J. Kavanagh.
Quiet for six months. Four fissures have opened in which there is fire,
which occasionally spurts out.
April 26 F. C. Autridge.
Seven cones pouring forth smoke; their interior a vast gulf of fire.
Stalactites hang from the roof of the dome.
Aug. 4 Visit of Samuel
Kneeland. Feels rewarded for the exertions made to come so far, the
volcano being moderately active.
August, 1872 A year
earlier Halemaumau was a deep cavity, but had filled up and is now
overflowing into the basin of 1868. T. Coan.
Oct. 21 D. H. Hitchcock
says Halemaumau is like what it was from 1845 to 1868, an immense dome
six hundred feet higher than the center of the pit, equaling in altitude
the bordering black ledges. On its summit are the two lakes from which
lava streams down in various directions. Nothing is left of the high
banks surrounding the old south lake.
Nov. 26 W. P. Ragsdale
says lava has been flowing to the foot of the west bank, (Uwekahuna),
and is now proceeding from the south lake in a covered canal towards the
north end. Pours over the bank in a cataract of fire.
Dec. 11-16 Grand flows;
unusually fine.
March 3rd, 1873 Mr.
Nordhoff reports that the great lake had been divided by a low ledge of
lava into two parts; each body having a diameter of five hundred feet,
circular, separated by a low lying ridge, and the two together
surrounded by a wall eighty feet high. The surface of the first lake had
a gray color. Molten lava was repelled from the borders to the center,
then flinging aloft fiery waves as much as thirty feet, followed by a
hissing sound. Fiery rings were constantly being pushed towards the
center, piling up lava fifteen feet above the general level. The second
lake was agitated more violently, spending its fury upon the southern
bank. The cliff was undermined for one hundred and fifty feet from which
the waves were repelled with a dull heavy roar. The word terrible best
represented the character of the agitation.
The heat back of the bank
was almost insupportable: a hot draught came from the cracks behind,
charged with sulphur. Still farther back were several cones. These
commenced as small vents through which lava is ejected and by a
secretion built up pipes twenty to thirty feet long, open at the top and
ruined by violent explosions. Inside was the molten lava and stalactites
yet in the formative stage waved in the wind. The cooled surface was
extremely thin.
In January, 1874 Miss
Isabella L. Bird, represented that the lake had an irregular shape five
hundred feet long, divided in two, with banks thirty-five to forty feet
high. June 4th the rock about the lake has risen much, and the
precipitous walls were thought to be eighty feet high. Six hundred feet
from the lake there was a blowing cone, like a beehive, twelve feet
high, forty feet deep inside, with walls two feet thick. It was throwing
up jets and clots of lava with a deafening roar and subterranean noises.
Halemaumau was on a hilltop. Eleven fire fountains danced around the
lake, half of them combining into one thirty feet high at the center. A
cone lower down discharged lava intermittently. The same month, Mr. J.
M. Lydgate presented a rough sketch of the caldera to the Government
Survey, from which is derived the restoration presented in Plate 33. The
two lakes of the previous observers appear and the area of the lower
pit formed in 1868 well shown. The black ledge was quite extensive and
probably at the same level as in 1868.
July 8 D. H. Hitchcock
says the crater is filling up with fresh lava, but the floor is sinking
more and more as a whole. Halemaumau has half the height of the lower or
southern lake. Two earthquake shocks were recorded for July 10.
Sept. 3 R. Whitman and
B. F. Dillingham saw the south lake moderately active.
Sept. 10 Lava broke
through the crust in the eastern edge of the basin and flowed rapidly
westward, spreading over several acres. It was all done in two hours. C.
E. Stackpole.
Early in October Mr. Coan
states that the lower pit of 1868 had been filled up about two hundred
feet, and the mass about Halemaumau had "become a tumulated elevation
nearly as high as the southern brim of the crater." In December Mr. J.
W. Nicols of the British Transit of Venus Expedition reports several
important features. There were four lava lakes, the largest six hundred
feet long, in which seven or eight fountains were playing near the
edges. One of the lakes filled to the brim, while the others were
surrounded by walls. The cone about the whole area was about seventy
feet high.
Dec. 8, 1874 H. M.
Whitney draws a rough plan of the lakes with a new nomenclature, which
was adhered to for some time. The more southern lake was called
Halemaumau, three hundred feet across. Eight hundred feet to the north
was Lake Kilauea, five to six hundred feet long and three hundred
across. The larger diameter of the depression was about five hundred
feet. Adjacent to Halemaumau there had been a third lake, active two
years earlier, but now closed up. The height of the north wall was one
hundred and twenty feet.
Feb. 2, 1875 F. J. Scott
draws a similar plan, and witnessed a great gush from Lake Kilauea.
Feb. 19 W .D. Alexander
saw action in Lakes Halemaumau and Kilauea.
Feb. 26 Prof. Joseph
Moore of Richmond, Indiana, said that Halemaumau was full and
overflowing: and there were four lakes in action.
Aug. 7 There were two
severe earthquake shocks.
A party from the English
Challenger Expedition report the lakes Halemaumau and Kilauea as
unusually active. There were five jets playing in the first, and the
same number of inferior importance in the second. The lava rose and then
subsided in the first. A small cone between the two blows jets of lava
from thirty-five to forty feet. A lava cascade poured to the northeast
of the second lake. Spectroscopic observations gave a continuous
spectrum, the red being the brightest and an occasional flame in the
green. Magnetic observations proved the presence of considerable iron.
Sept. 3 More active than
for a long time.
Sept. 6 W. M. Gibson
writes that Lake Kilauea had risen about ninety feet. Streams flowed
from Halemaumau and Kilauea-iki into Lake Kilauea; also to the
southeast. He could see from the Volcano House lava jets leaping above
the banks; so that the lava must have risen a hundred feet during his
visit.
Jan. 14, 1876 Lake
Kilauea sent forth a broad stream into the caldera for four hours.
Feb. 22 Both lakes in
full activity. A. 0. Forbes.
April 20 Cascade of lava
into a pit seventy-five feet to the south of lake. River from below
cliff; both streams of short duration.
May 2 D. H. Hitchcock.
Halemaumau has built itself up two hundred feet in one year. Lava from
the south lake has almost filled up the great central depression. Six
streams running down Halemaumau all night.
July 9 Lava streams
running four miles per hour. T. K. Noble.
Aug. 25 E. H. Butler of
Hobart, Tasmania, and others. Lakes full to overflowing, covering fifty
acres on the west side. Waves of fire continually leaping twenty-five
feet into the air.
Jan. 1, 1877 W. P. Toler
compares present conditions with those prevailing in r843 and 1845. Then
the bottom was four hundred feet lower than it is now. Then the lake was
ten to fifteen feet below its banks; now it is depressed for two hundred
feet in a cone that is one hundred and eighty feet high. Then the
activity was in the lakes; now the lava flows over a hardened surface.
Then there was only one lake; now there is a depression of two hundred
feet where a second one has existed, though now extinct. Much rock has
fallen from the high cliffs. He can now read newspapers by the light of
the fires, upon the north bank.
May 4 Large party found
"more activity than has been seen since r868." Nineteen earthquake
shocks during the evening. Plenty of subterranean fire and some flowing
lava.
May 6 S. B. Dole reports
the formation of a fissure extending from the floor through the bank and
into the woods beyond, just before his arrival. Lava spouted from this
crevice fifty to one hundred and fifty feet into the air. Halemaumau
drained. Estimated depth of hole at two hundred and fifty feet.
May 8 H. M. Whitney
finds this opening and gathered tresses of Pele's hair twenty inches
long.
May 21 T. E. Cook found
a place one and a half miles south east from the Volcano House, where
lava had come out of a crevice some two hundred feet below the top.
These last three observations may point to Keanakakoi. Pea Wilkes, with
his father, witnessed an eruption at Keanakakoi in 1877, which may be
the same with that mentioned by Mr. Cook. The whole floor was a
bubbling, boiling mass sending surges from side to side. The heat was so
great that they could approach it only on the windward side.
Aug. 2 Lava rose
thirty-five feet in the south lake in a few days.
Sept. 4 E. O. Hall
thinks the floor is five hundred to six hundred feet higher than in
1837.
Sept. 8 Bottom of South
lake fell fifty feet. W. H. Lentz.
Oct. 2 Crater active. H.

Oct. 9 Rev. W. P.
Alexander says: "I visited this volcano forty-five years ago. It was
much more active then than now."
Dec. 2I Overflow

Jan. 1 1878 Volcano very
active. W. H. Lentz.
Jan. 18 Curtis J. Lyons
calculated altitudes with an aneroid barometer. Foot of the road down to
the crater and level of Halemaumau five hundred and three hundred and
fifty feet below Volcano House. Height of Uwekehuna six hundred and
fifty feet above its base. Halemaumau four hundred feet long, one
hundred feet wide. Lake Kilauea not approachable. Extensive flows of
lava from it on the north side running N. N. E. for three-fourths of a
mile. Present height of cone estimated at one hundred and seventy-five
feet.
June 8 Two flows between
the old north and the present south lake.
June 28 Rev. L. H.
Hallock. "A surging mass of lava, dashing like surf against the walls of
Halemaumau and throwing gory clots high over the ledges, with Pele's
hair streaming in the whiffs of rising gas, accompanied by a roaring
like that of the sea, was the never-to-be-forgotten experience of our
day at the volcano."
Sept. 20 J. Mott Smith.
"In my former visits, 1851, 1856, 1862, I saw no display of fire to
compare with what is now seen. The floor of crater much changed and
elevated. Whole floor is in constant motion rising and subsiding by
turns."
Nov. 24 Very active;
lava within twelve feet of the top of the bank.
Jan. 7, 1879 H. M.
Whitney. Two lakes now as formerly, lava nearly up to the brim but not
overflowing; lava breaks out on the sides and fills up the center. By
night, fires seen in every part of the crater. Some parts of the hill
surrounding south lake as high as the south wall of Kilauea.
Jan. 8 Wm. Gardner.
South lake with lava fifty feet below the rim and boiling like water.
There was at this time one
large lake enclosed by a crag wall twenty feet above the fire. These
crags increased till April, becoming four hundred and fifty feet high.
Fire now less than forty feet from the top. Lentz said to have counted
three hundred and seventeen different points from which fire was
bursting at one time. Reported by Miss C. F. Gordon Cumming.
The eruption came April
21. The bottom dropped out on this date. W. H. Lentz.
Dr. Coan, in a letter of
June 20, said that the lake, which had been overflowing its banks and
whose rim had been raised till it was nearly as high as the outer wall,
was suddenly emptied by an underground discharge and subsided several
hundred feet, leaving nothing but a "smoking basin."
April 28 Almost extinct;
some vapors. A. 0. Forbes.
The fire returned very
soon. June 24 W. H. Lentz states that both lakes were active; jets of
lava, appearing like a fountain of fire from the Volcano House were
thrown up. William Tregloan writes that on July 2nd the two lakes had
become one, of enormous size, throwing lava to the height of fifty feet.
July 14 Lentz reports a
flow of lava extending over one-eighth of the entire bottom. The sulphur
banks on the southeast side caught fire. A large part of the bank of
south lake fell in. The bottom of Keanakakoi is covered by a smooth
black lava, very fresh looking, which is supposed to have been ejected
at about this time. The faulted block let down upon the northern side of
this pit must have reached its present position at an earlier date.
In October, Miss C. F.
Gordon Cummings visited Kilauea. She represented that after the
discharge of April 21 a wall of blocks or crags rose around Halemaumau
to the height of three hundred and sixty to four hundred feet. October
27 there were fiery waves tossing over this lake. Two days later she
climbed "six hundred feet" of these rough blocks and was disappointed at
not seeing much liquid lava, though fire was visible in the inside cup,
and fountains shot out horizontally from the base of the crags. She
figures several large spiracles in the midst of the lakes.
Dec. 2 H. G. Kelley
could find no flowing lava. Long sticks thrust down in crevices would
ignite.

The Conditions of 1880
By May, 1880, according to
Mr. Coan, Halemaumau had become a boiling lake discharging copious
streams into the great central basin. In July, Professor W. T. Brigham
paid another visit to the volcano. He considered that during the
previous eighteen years Kilauea must have increased five per cent. in
its lateral dimensions. The floor where first trod upon was six hundred
and fifty feet below the Volcano House and the central portion three
hundred feet; or, in other words, the floor was raised as a flat dome
three hundred and fifty feet high, which had accumulated partly by the
natural building up by accretion and partly by an irregular elevation.
Halemaumau had now become a regular dome surmounted by four lakes having
an average diameter of 1,000 feet each. The lake of 1865 seemed to have
lain in the midst of these four lakes, no one of them by itself
reproduced from its progenitor. The latest one began to form May 15th
and its bank was nearly on a level with the surrounding rock. The others
had stratified walls, sometimes an hundred feet high, from which blocks
were constantly falling because of the undermining action of the lava
beneath. As seen at night these molten lavas were white hot. In earlier
visits blue and green flames were observed, seldom lasting more than a
few minutes. Now the flames issuing from a cluster of blow holes burned
constantly with these colors, the time of continuance exceeding twelve
hours. Very little steam was thrown off at this time. The southern
sulphur bank had wholly disappeared, having been consumed by a fire
occurring a few months earlier.
Sept. 18 The "New" lake,
starting in May, increased to the circumference of 3,000 feet with sides
from fifty to sixty feet high.
Sept. 25 Severe shock of
earthquake. Lentz.
Oct. 27 New lake said to
be one hundred and eighty to two hundred feet below top of its banks.
Both lakes quite active. L. P. Tenney.
Nov. 4 W. Bolsea
describes three lakes. Lava flowing on north side of Lake Kilauea
crowded into very small dimensions. Halemaumau remains as it was
eighteen months previous, but is inaccessible. The special seat of
activity is a new lake to the southeast not far away from Halemaumau.
Activity vigorous but not violent. No apparent sympathy between the two
lakes.
Dec. 7 J. M. Lydgate
finds Volcano House 4,021 feet above the sea by syphon barometer.
Feb. 15, 1881 Fountain
of lava streamed up northwest of rough pile and spread lava over much of
the floor.
Feb. 20 New lake very
active.
July 20 Four lakes
visited, viz., Halemaumau, New Lake, Old Lake and South Lake. New Lake
specially interesting. Lava in it rose and fell twenty feet. A bright
red spot appeared in the farther corner, the crust cracked, red lines of
lava appeared, pieces of the crust thirty feet long sank beneath the
surface and the whole mass was boiling. W. W. Hall, Miss H. S. Norton
and others.
Aug. 2 Flow of lava from
New Lake.
The same from Halemaumau
Aug. 5.
Aug. 15 N. B. Emerson
reports activity in New Lake. Fountains thirty to forty feet high; waves
dashing against cliffs; tables of black lava drawn into the settling
vortices.
Aug. 19 New Lake has
become the "show" crater. Much the same as when last described.
Oct. 25 T. H. Davies.
Surface of New Lake always agitated. Nine caldrons splashing twenty feet
high. Halemaumau has more jets. A pit of fire also to the right.
Considerable flow of lava.
Jan. 16, 1882 S. C.
Damon had a grand view of the breaking up of New Lake.
March 7 Lakes break up
both in day and night time.
March 30 Additional lava
poured into lakes.

Captain Dutton's Visit in 1882
A very
complete and satisfactory account of Kilauea is that given by Captain
Clarence E. Dutton in the Fourth Annual Report of the United States
Geological Survey and the attempt will be made to present its most
important points. He applies to the volcano with some hesitation the
term Caldera, which is equally appropriate for Mokuaweoweo, Haleakala
and other Hawaiian examples. It is what Wilkes, and after him Dana,
calls a pit crater. Geikie uses caldera to signify explosion-craters
and crater lakes, citing as examples Palma in the Canary Islands, Val
del Bove in Etna, eleven illustrations in Ecuador, the crater Lake
Mazama in Oregon, and others. The origin of Kilauea is not so clearly a
case of explosion as in the other cases cited. Dutton, however, does not
enter into the discussion of the origin of the caldera. Plate 34 is a
copy of a panorama presented in his report.
Starting from
the Volcano House the path leads over a series of steps that have been
faulted off from the main platform of the country. On reaching the
bottom the way leads over freshly formed pahoehoe, rolling
smooth-surfaced bosses, not much inclined, but at about one and
three-fourths miles the slope is much steeper for about one hundred
feet. Reaching the summit he came to the "New Lake," said to have
appeared first in May, 1881, being about four hundred and eighty feet
long and over three hundred wide, surrounded by walls fifteen to twenty
feet in height.
"When we
first reach it the probabilities are that the surface of the lake is
coated over with a black, solidified crust, showing a rim of fire all
around the edge. At numerous points at the edge of the crust jets of
fire are seen spouting upwards, throwing up a spray of glowing lava
drops and emitting a dull simmering sound. The heat for the time being
is not intense. Now and then a fountain breaks out in the middle of the
lake and boils freely for a few minutes. It then becomes quiet, but only
to renew the operation at some other point. Gradually the spurting and
fretting at the edges augment. A belch of lava is thrown up here and
there to the height of five or six feet and falls back upon the crust.
Presently, and near the edge, a cake of the crust cracks off, and one
edge of it bending downwards descends beneath the lava, and the whole
cake disappears, disclosing a naked surface of liquid fire. Again it
coats over and turns black. This operation is repeated edgewise at some
other part of the lake. Suddenly a network of cracks shoots through the
entire crust. Piece after piece of it turns its edge downward and sinks
with a grand commotion, leaving the whole pool a single expanse of
liquid lava. The heat is now insupportable, and for a time it is
necessary to withdraw from the immediate brink. Gradually the surface
darkens with the formation of a new crust, which grows blacker and
blacker until the last ray of incandescence disappears. This alternation
of the freezing of the surface of the lake and the break up and sinking
of the crust goes on in a continuous round, with an approach to a
regular period of about two hours. The interval between the break-ups
varies, so far as observed, from forty minutes to two hours and a
quarter. Probably the average interval is somewhat less than two hours.
The explanation of the phenomenon is not difficult."
The following
is an abstract of the text: Melted silicates occlude notable quantities
of water and when they solidify they exclude the water just as water
itself excludes air in freezing. The excluded gases are mechanically
entangled as bubbles which are numerous enough to diminish the density.
The first inch or two of crust which forms is cooled quickly and becomes
stiff and black in a few minutes and is termed tachylite. Being full of
vescicles and spongy it is light enough to float. Subsequent additions
to its thickness are made to its under surface. These become more and
more compact through the disingagement of the gases, thus increasing the
specific gravity. when this has considerably increased the position is
unstable, and rupture once started is quickly propagated through the
entire crust, which goes to pieces and sinks.
Less than
half a mile northerly is the greater lake or Halemaumau, nearly 1,000
feet long, six hundred feet wide, and five hundred and eighty feet below
Uwekakuna. It is surrounded by cliffs an hundred feet high with a plenty
of talus of irregular blocks. The lava is more active; the surface is
covered with boiling fountains, but they do not spout high. Because of
the unquiet surface the crust cannot form as at the-New Lake with
regularity. There are occasional thin detached sheets which sink from
time to time. The outer cone is composed of masses of lava that have
been pushed up with much shattering and contortion. There are cones
within cones, more like a crater. That it has been elevated is testified
to by those who have occupied the Volcano House since 1875; and the
greater part of the elevation has been affected the previous three
years.
Captain
Dutton ascribes the ebullition of the lava to steam and gases. Much of
the visible steam comes from the fissures and numberless vent holes in
the walls. Over the entire surface of the burning lakes is spread a pall
of translucent vapor. Of the vapors he recognized the sulphur gases and
considered that the bleaching of the brilliant orange and saffron colors
of certain patches was due to hydrochloric acid.
To the
southwest there existed another lake, which had been opened up about
three years earlier, known as the "Old South Lake." Great quantities of
pungent gas exclude from numberless fissures, and the surface is hot.
There are occasional small eruptions over its surface.

The
Author's Visit In 1883
By the record
of the visitor's book Captain Dutton was at the Volcano July 14, August
4, and September 12. The author arrived there February 9 in the
following year, in company with Rev. A. 0. Forbes of Honolulu, who from
his familiarity with the Hawaiian language was able to locate the proper
positions of Kilauea iki, Poli o Keawe and Keanakakoi. Several days were
spent in the vicinity. At the first inspection it was possible, after
dark, to count ninety places from the Volcano House brink where fire was
visible. This, of course, included many repetitions of single streams of
which portions were concealed by intervening ledges.
In general
the phenomena observed were the same with those described by Captain
Dutton and it will be unnecessary to repeat what has just been
described. In the New Lake the lava seemed to spurt up in jets six to
eight feet high, and they resemble the drawings of fire tempests on the
surface of the sun as given in astronomical text books. The drops spun
out to make Pete's hair were observed to dart a distance of eighteen or
twenty feet. The description of the behavior of the lava in New Lake
cannot be improved. I counted a hundred jets visible at one time.
The cliffs
about the lake were nearly fifty feet in height. The instant when the
heat was most intolerable was just before the break-ups; and I accepted
the explanation of Nordhoff, that this heat filled the crevices behind
us because the stiffened crust prevented its escape into the air and it
therefore made its way outward in the crevices.
These periods
of breaking up came regularly every hour. The outlet was at the north
end; and February 9th it discharged copiously, so much so that it was
impossible to return to the Volcano House by the direct road which had
been taken in order to reach the lake. We had no difficulty in obtaining
discharges of liquid lava by punching the dome-like structures held in
position simply by a thin stiffened crust. The color of the flame
contained more of the orange element than is apparent in ordinary fire.
Halemaumau was reached with some difficulty and displayed the same
freezing and breaking up observed in the New Lake. It was surrounded by
three rough walls, rudely concentric with the borders of the fire. See
Plate 35.
It was a true
crater in distinction from the application of the term caldera to the
entire pit. The steam cloud rising from Halemaumau was turned either way
according- to the wind, and presented a general resemblance to the
"Pine-tree" of Vesuvius.
In examining
the fissures near to and far away from Kilauea, it was observed that
they were generally parallel to the walls of the caldera. Apropos of the
question of the relations of Kilauea to Mauna Loa, it was noticed that
the ground falls off about five hundred feet before reaching the base of
the latter dome. Hence it seemed to be an entirely independent
elevation; and the continuation of the basaltic sheets from every side
till they met in the air over the pit would have made an eminence
several hundred feet higher than the plain is at present.

Eruption of 1886
The
Halemaumau pit was completely filled up on the evening of March 6th,
1886. The lava that for nine years, or since the last previous important
discharge (1877) had been accumulating and pouring over the floor from
Halemaumau and New Lake, the latter five years old, attained the
altitude of about 3,710 to 3,730 feet above the sea. The bottom of the
pit of Kilauea was convex the top being about one hundred and sixty
feet higher than at the northern edge, while the general level averaged
from two hundred and fifty to three hundred feet above the black ledge
of 1840.
Much of the
old sulphur bank had been covered and the precipice at the southwest
corner had mostly disappeared. Late in the evening there commenced a
series of earthquakes so severe as to alarm J. H. Maby, of the Volcano
House, and his family. Forty-three shocks were noted up to 8 A.M. of the
7th instant. After the fourth quake the light disappeared.
For three
days the heated vapors had been uncommonly hot, but on the 6th and 7th
instant ceased entirely. About midnight the lava disappeared. Plate 38-1
may show the convex outline before the eruption and Plate 38-2 the
appearance of the contour afterwards. At first, however, the walls must
have been more nearly vertical. Later large blocks of the black lava
fell down, and there was a talus on all the steep slopes. From five
hundred and seventy to five hundred and eighty feet thickness of rock
fell away directly beneath the Halemaumau lake. The adjacent New Lake
was comparatively shallow, one hundred and fifty feet. The central pit
was about three hundred feet in diameter. Plate 36 shows the appearance
of Halemaumau after the withdrawal of the lava; and Plate 37A a ground
plan of the triangular area affected.
Compared with
the earlier discharges this was very small. The main depression is of
triangular shape with sides about 3,350 feet long, forming an area less
than half a mile square. In extent it is not very unlike Kilauea iki,
though the basin carries less cubical content. On the east side there is
a rudely semicircular depression where New Lake was, with its floating
islands of rock. It makes a sort of shelf averaging one hundred and
sixtyfive feet in depth. The entire floor of the caldera is now the
black ledge and the lower pit only the diminutive half a mile square
area of Halemaumau; and the mass that has disappeared is so small that
it is hardly worthwhile to seek to discover where it has gone.
It is to be
expected that the liquid might ooze from one of the great fissures
extending southwesterly for several miles towards Pahala, and be
scarcely noticed as the region is mostly a barren uninhabitable waste.
In my sketch of this eruption, June 7 to 14, I have stated that besides
the formation of the pit there were produced several large fissures in
the neighborhood; one on the Poli o Keawe, at the sulphur banks near the
Volcano House, and two on the road to Keauhou, two miles distant.
Mr. J. S.
Emerson was at Kilauea between March 24th and April 14th, taking
measurements for a map. He saw no molten lava, but could discern
evidences of heat. Rev. Mr. E. P. Baker and Mr. Emerson both descended
into the pit. On the eighth of June I descended to its very lowest
depth, nine hundred feet below the Volcano House. To the depth of about
three hundred and twenty-five feet, embracing nearly all the triangular
area, the sides were covered by irregular slabs of pahoehoe, six or
seven feet long, four or five feet wide and a foot thick. These were the
crust of the lava at its greatest development, and they naturally fell
on the slope so as to lie quite uniformly, though some fragments were
tilted in every direction. The small lower pit, some six hundred feet
across, was covered by the ordinary grayish lava blocks, and there were
small jets of vapor. On the east side of this pit on June 8th, I found a
hole about four feet in diameter, nearly vertical, reaching down perhaps
as deep as the pit, to a mass of molten lava. Great volumes of steam and
sulphur vapor poured out of this orifice, whose walls were lined with
sublimed sulphur and Pele's hair. As this opening was situated in the
midst of loose blocks of rock and widened out downwards, it was
dangerous to stand near it; but the swashing of the liquid was
distinctly audible and stones thrown down were heard to splash into the
liquid. By my advice my companion withdrew from the edge of this
opening, and immediately afterwards the rim fell down into the fire. Had
not my friend taken my advice he would have lost his life. About two
hundred feet northwards from this opening there was a copious discharge
of corrosive vapors, which increased in strength in the course of the
following week. The fire in this opening continued to enlarge by
absorbing the walls. June 25th two vents opened upon the west side of
the pit, and lava flowed from the well originating June 8th, filling up
the pit.
The further
history of this spot is given by the statements of Professor L. L. Van
Slyke who saw what was transpiring July 19th. The conical pit was not
nearly filled up but there was a mound of lava blocks one hundred and
fifty feet high taking its place, with a depression encircling it. A
lava lake of about five acres in extent appeared in this depression and
there were other active fires. He says: "Ascending the cone part way, I
came to the edge of a deep hole or well, of rather irregular outline,
foursided, perhaps thirty or forty feet wide, and from sixty to
seventy five feet long, and not less than a hundred feet deep. The
mouth was surrounded by masses of loose rocks, rendering approach to the
edge impossible or very dangerous, except at one point; from this point
I could see the bottom of the well, and that it was covered with
hardened fresh pahoehoe. At one side the liquid lava could be seen as it
was puffed out of a small hole every few seconds and thrown up a few
feet. The puffing noise accompanying the ejection of the lava was quite
like that of a railway locomotive, though louder. The aperture through
which the lava was thrown out might have been three feet long and two
feet wide. Immediately beneath the point where I was standing there
seemed to be a constant and tremendous commotion, attended by a peculiar
swashing noise, but I could not lean sufficiently far over with safety
to see anything. Fumes of sulphur dioxide were coming up in abundance,
but being on the windward side I was not greatly annoyed by them."
From the
southeastern side he ascended the cone and came to "a second well or
deep hole, where molten lava was visible. This well was nearly round,
with a diameter of perhaps twenty or thirty feet, and a depth of about a
hundred. Like the other well, the sides were perpendicular. At the
bottom was a cone having an opening at the top perhaps ten feet across;
and inside liquid lava was boiling with intense violence, every few
seconds throwing up a jet of Java, the spray of which came to the mouth
of the well almost into my face."
In addition
to these holes, Professor Van Slyke visited a lake of lava located
beneath the west wall of Halemaumau in the depression, and extending
about four hundred feet to the "smoke jet." At first the surface was
hardened and black; later there were spasmodic discharges of lava.
In September
Mr. F. S. Dodge spent a fortnight at Kilauea observing the growth of the
cone in Halemaumau and perfecting the data for a map supplementary to
that of J. S. Emerson. A drawing made October 18th, Plate 37B, shows
several steam holes upon the surface of the cone, a to g. Mr. Dodge
noted the rise of the general floor due to the flow of the lava from
Halemaumau. He also measured the debris-cone whose beginning bad been
described by Van Slyke. It was 1,080 feet broad from N. E. to S. W.,
1,100 from E. to W. and nine hundred and thirty from N. W. to S. E.
Hence as the width of the general basin was 2,300 feet there was a
depression encircling the cone with a width of from five hundred to
seven hundred feet. The highest point on the cone was not quite as high
as the surrounding black ledge. A section showing the relations of the
cone and the black ledge appears in Plate 38, No. 3.
The most
important discovery made by Mr. Dodge was the fact that the whole basin
with the cone was rising at the rate of nearly one foot daily. By
January 14th, 1887, it had risen two hundred feet since October, 1886,
as though floating upon the surface of a liquid lake. One of our
illustrations shows this cone as it appeared in October.
Nov. 4, 1886
W. R. Castle noticed that heat was perceptible in the fissure of 1868
near Kilauea iki. He also visited Kamakaopule, a crater southeast from
Kilauea iki. It is a pit five hundred feet deep, one-half of which is
filled with sand. Steam was issuing from a crevice in the road quite
near it. And it is said there is a very hot mound, now perceptible,
(1908), west of the road, towards Kau.
In August,
1887 Kilauea was visited by Professor J. D. Dana, who has fully
described the history of Halemaumau since the eruption in March, 1886.45
He found the top of the cone to be high above the rim of the Halemaumau
basin; and that it was literally a debris-cone made of fragments of the
lava crust and not of loose scoria such as comes from the central vent.
"In the basin about the cone, the chief boiling lava lake was on the
west side, in full view from the top of the west wall. The lake was
about one hundred and fifty by one hundred and seventy-five feet in its
diameters. Although mostly crusted over, it showed the red fires in a
few long crossing lines (fissures), and in three to five open places,
half-way under the overhanging rock of the margin where the lavas are
dashing up in spray and splashing noisily, with seemingly the liquidity
of water. Now and then the fire places widened out toward the interior
of the lake, breaking up the crust and consuming it by fusion; yet at no
time was there a projection of the lavas in vertical jets in a
par-boiling way; nor was it too hot to stand on the border of the lake
if only the face were protected. Although relatively so quiet, the
mobility of the brilliant splashing lavas made it an intensely
interesting sight. Occasionally the red fissures widened by a fusing of
the sides as the crust nearby heaved, and the lavas flowed over the
surface. It was evident from the cooled streams outside, that now and
then more forcible movements take place, followed by outflows over the
margin; when the whole lake is in action. There were no true
well-defined jets rising and falling over any part of the surface, like
those of 1840, a condition requiring a little more heat; but the
splashing at the margin, also due to the escape of vapor bubbles, had
all the freedom of movement of splashing waves on a seacoast. The
existence of the half-covered caverns along the margin, which the
descriptions show to have been the most common feature for a score of
years, was owing to the protection from cooling given by the overlying
rock. All parts of the basin had been overflowed from fissures or
temporary lava pools." This pool has since been named Dana Lake.
Our friend
took great interest in the formation of the wrinkles on the surface of
the cooled lava streams which give the look of tapestry folds, and are
similar to the ropy lava of many authors. The stream of lava moves
beneath the thin crust while it is cooling; and the little waves thus
produced are too stiff to fall back to their original horizontality. The
wrinkles must be at right angles to the direction of the movement. Good
photographs of recently cooled lava show both these concentric tapestry
lines and also many oven-shaped domes sometimes fifteen or twenty feet
high. Commonly their surfaces are broken because of the running away of
the molten lava inside and the inability of the roof to sustain weight.
One often develops this fracture in walking over an old lava stream.
The vapors of
sulphur may assist in the making of these ovens or domes, and will leave
in the spaces below yellow and white incrustations and stalactites of
glauber salt and gypsum. Instead of a scoriaceous crust when the lava
exudes through fissures, the surface may be composed of glass, as the
scoria material is not present.
The changes
ensuing, seen in September, consist in a longitudinal division of the
west wall, showing vapors rising from the whole length of the western
section. By March 8th, 1888, the cone had risen so high that the summit
was "on a line with the outside walls of the crater beyond it, looking
from the Volcano House." The whole mass, both the cone and the
depression around it, had thus risen nearly forty feet since August.
Still:
further changes were apparent in July, 1888, illustrated in our
reproduction of Mr. Dodge's map and section, Plates 38, 39A.
The conical
mass seems to be subdivided into four elliptical cones encircling a
space concealed by vapors of unknown depth, where molten lava may be
existent. These subordinate cones are from one hundred and sixty to one
hundred and twenty-five feet above the surrounding black ledge. The
whole area of what was the depression of March, 1886, is also elevated
above the black ledge, and lava from the central vents pours down into
the old hollow where the New Lake once existed. On the west side of the
cone the Dana lake has been further developed; there were six small
discharging cones ten to twenty feet high outside of the central more
highly elevated mass.
Dec. 22, 1888
L. A. Thurston says the activity is greater than ever before. From the
Elephant's Head a flow of aa proceeded four days ago. A dozen blowholes.
Lava lake has a confining wall built by itself, five feet thick. Lava
rose and fell several times to the extent of three or four feet. A layer
of Pele's hair four inches thick.

remarkable activity. No eruption. Mrs. S. J. Lyman.
In May E. P.
Baker wrote to Professor Dana that there was at this time a subsidence
of eighty feet in the floor of Halemaumau which carried down the large
central debris cone, leaving vertical walls about the great depression.
There was a fissure in the floor of Kilauea which may have drawn off
this lava and transported it a comparatively short distance.
On July 4
there was a stream of lava from Dana Lake, flowing towards the cone.
July 18 A.
B. Lyons says there is a cone of debris two hundred feet high, from
whose base perpetual clouds of steam and sulphur are issuing. The mass
floats upon lava deep down. It is in the center of a triangular
depression 2,400 feet in diameter, surrounded by precipitous walls
twenty to thirty feet high. On one side is a lake of lava one hundred
and seventy-five by one hundred and twenty feet.
Jan. 2, 1890
E. P. Baker says a crack N. W. and S. E., corresponding to the outside
of the area that has been lifted vertically, formed Nov. 4, 1889. Plate
40A represents the lake in 1890, the exact date not being given. Taken
by Williams of Honolulu. Shows well the appearance of a black ledge
encircling it and fragments of the congealed crust.
Jan. 2, 1891
L. A. Thurston reports great activity, Dana and the new lake boiling,
throwing lava from forty to sixty feet. The wall about Dana Lake more
conspicuous and the surface of the lava about ten feet above the
surrounding country. Climbed the north wall of the central cone of
Halemaumau.

Subsidence of the Debris Cone
It is worthy
of note that in the next series of changes the area of the more elevated
part of this cone becomes the depressed area of August, 1892, as shown
by the section and map of that date; and a description of the changes
follows.
S. E. Bishop.
In the collapse of March 7, 1891, the debris cone, Dana and Maby lakes
disappeared, leaving a pit seven hundred feet deep. Lava soon returned,
and for one year has been gradually rising. In Dana Lake the lava had
issued quietly from the center towards the walls and descended carrying
sections of the crust. Now the edges are quiet. The current starts from
east of the center and flows westward. Pieces disappear in the vivid
melee of the center. The cone form of Halemaumau becomes more distinct.
(Written April 11, 1892.)
There was a
slight earthquake when the change took place, and it was exactly five
years between the last two collapses. As the debris cone was about two
hundred feet high its apex was only eighty-eight feet below the Volcano
House, the highest point attained by the rock during the whole history
of the volcano, or 3,935 feet above the sea. The melted lava probably
reached the height of three hundred and seventy feet below the Volcano
House.

R. Castle says that Halemaumau is a profound abyss I,800 feet in
diameter and nearly three hundred feet deep. Mr. E. N. Hitchcock

M. Whitney says the lake is 1,000 to 2,000 feet across, throwing up
several large jets and thousands of small ones. There are two openings
near the center allowing the lava to ascend and descend.
Feb. 12, 1892
L. A. Thurston. Diameter of the pit 2,500 feet. It is two hundred and
fifty feet down to the black ledge, which is twenty-five feet high and
two hundred feet broad. It is 1,300 feet from bank to bank of the lake
next to the black ledge. J. M. Lee says that two months ago the molten
lava sank one hundred and fifty feet below the level of the black ledge.
After one month it began to rise again and lacks now only twenty-five
feet of its pristine level. Lava boiling with bursts of spray
twenty-five feet to fifty feet. No upward thrust. The filling is by
overflow from the central lake.
The condition
of things in Kilauea after the changes of March 7th, 1891, have been
very intelligently described by Professor A. B. Lyons. He spoke first of
the appearance in1889, and found in 1892, July 11, everything so changed
that nothing in the vicinity of Halemaumau was recognizable. The
debris-cone with the attendant clouds of steam and smoke had vanished.
From the hotel, one would say that the volcano has entirely disappeared;
and nothing suggestive of great importance was perceptible till the pit
itself was close at hand, which was enclosed by a precipice constituting
a circular rampart two hundred and fifty feet deep, half a mile in
diameter. The sides consisted of irregularly bedded lava varying in hue
from gray to brick red; the floor of fresh black pahoehoe with a fluid
center or lake partly quiet and partly boiling like a witch's caldron.
The lava pool occupies about fifteen acres with banks from five to ten
feet high.
The lava
blocks are loosely piled beneath the precipice over which by care it is
possible to make one's way. The lake is twenty-five to thirty feet
higher than the base of the walls of the pit. On the south side the lake
is held in place by a sort of levee of slight thickness over which the
lava pours in a magnificent cataract not less than fifteen feet in
perpendicular height.
So much lava
rises from below that the level of the lake is constantly rising and
changing its area. One evening there were overflows from three different
points at once, and within two hours' time fifteen acres of the black
lava were inundated. The heat is intense, and one is in danger of being
bombarded by the spurts of the fiery liquid. It was dangerous to go to
leeward of the lake because of the unexpected flows of lava which might
cut off one's retreat or raise the temperature of an enclosed space to
an unendurable degree.
A more minute
description has been given by Professor Lyons as he sat by the brink of
the lake in a secure position. "As daylight fades the walls of the pit
begin to glow with the reflection of the lurid volcanic fire; the clouds
which the trade wind brings over the crater catch the same unearthly
light which brightens with the outburst of each new fountain below. As
the darkness deepens, the light from the lava jets and surges becomes
fairly dazzling to the eyes, and the action is kept up almost without
intermission, now at one point only, again along half the circumference
of the lake, or over areas of a n acre or two in the center. There were
certain lines along which the ebullition would take place repeatedly,
sometimes continuing hours together, sometimes only momentarily at
somewhat regular intervals; the lava would be thrown to a height of
fifteen to thirty feet, small clots, appearing like sparks, shooting
often to double that height. The peculiar sullen or angry roar of the
fiery surf could be often distinctly heard and was at times startlingly
loud. Frequently, too, the radiated heat could be distinctly felt when
there was an unusual outburst.
"The crust
which by daylight had appeared to be uniformly black is seen in the
night to be crossed with a network of cracks and fissures through which
the light of the glowing metal can be seen. These appear sometimes
simply as sharply defined lines, forming a more or less intricate
pattern, which is, however, momentarily changing. This is when the lava
crust is under no particular tension. Again the lines of light will be
seen perhaps sharply defined on one side but shaded through tints of red
to darkness on the other, the effect being produced by a force drawing
the crust bodily away from the crack on one side. Frequently a crack
will be shaded in this way on both sides, and will presently divide into
two parallel lines of light which will slowly separate from one another.
When the
current pushes the crust before it on the other hand, it will yield
suddenly, one edge will be forced up and the other down, so that
presently the crust will break into blocks which will be successively
engulphed. Then a fountain will perhaps suddenly burst through the
crust, tossing about its fragments, some of t hem a ton's weight, like
bits of drift wood in the eddies of a mountain torrent. Then at some
point the flood will rise above its embankment, and almost without
warning a lava stream will begin to flow, becoming presently a river of
living fire. The whole pit will be ablaze with vi vid light; the flood
will spread until it reaches the foot of the enclosing wall, glowing at
first like molten iron drawn from the smelting furnace, then changing to
a lurid red except where the feeding river continues to flow, and so
fading until it shows only here and there glaring eyes of fire looking
out from cavernous depths. It is as futile to attempt description as for
the painter to try to present on canvass anything but a travesty of a
volcano."

Goodale. Since 1847 the uprising of the whole floor has been the
noticeable feature of the volcano, and after every breakdown the lava
comes back to Halemaumau. This word means "the fixed, lasting,
unchanging, everlasting, ever continuous, house." No sense in saying
"Fern house" or "House thatched with ferns;" any such structure was back
of the Volcano House. (Westervelt.) No Hawaiian has ever written the
name Halema'uma'u; and they call the Caldera Ka lua o Pele "The pit of
Pele.''

stones, lava and dust thrown high into the air with spouting columns of

height of one hundred feet, leaving an abrupt wall over the lake with a
steep, broken slope toward the north. It appears to have been lifted up
by lava pressing from no great distance below, and a stream has
constantly emerged from the northeast slope of the hill ever since. Much
more steam than usual comes from all the cracks, even up to the sulphur
banks.

The
Breakdown in 1894
For about two
years the liquid had been accumulating, till finally it filled the pit
and oozed forth from the highest part of the immense column. The borders
of the fused lava cooled more quickly than the interior; whence it
resulted that the refrigerated mass accumulated around the edges of the
pool and kept increasing till a basin was formed, very much like the
bowls in the Yellowstone Park that accumulate from the cooling of the
lime compounds in the water except that the refrigerated mass was
outside of the basin; and the shape produced might be likened to an
inverted saucer. The Frontispiece shows this lake when at its best
development, and Plate 42 is a view of the edge of the same at the south
end taken from below.
This eruption
marks a climax in the history of the volcano, representing the highest
elevation attained by any lava lake in Halemaumau, two hundred and
eighty-five feet below the Volcano House, or 3,755 feet above the sea.
Pele may excel this record in the future; and in that case she will
probably send a burning stream into Kau, for the barrier to be overcome
there is only about fifteen feet.
In the early
part of July Mr. L. A. Thurston and party witnessed this unprecedented
series of changes. The account of it was spread upon the Volcano House
record and sent to the P. C. Advertiser from which the following notes
are compiled:
"Upon
arriving at the volcano on July 5, 1894, the principal change since Mr.
Dodge's visit was found to be the sudden rising of the north bank of the
lake, covering an area of about eight hundred feet long by four hundred
wide, which, on the 21st of March last was suddenly and without warning
elevated to a height of eighty feet above the other banks and the
surface of the lava, the lake being then full. The raised area was much
shattered. Two blow-holes shortly afterward made their appearance on the
outer line of the fracture. April r8th the hill thus formed began to
sink, and on July 5th was only about thirty feet above the other walls
of the lake. On the evening of July 6th, a party of tourists found the
lake in a state of moderate activity, the surface of the lava being
about twelve feet below the banks.
On Saturday,
the 7th, the surface of the lake raised so that the entire lake was
visible from the Volcano House. That night it overflowed into the main
crater, and a blow-hole was thrown up, some two hundred yards outside
and to the north of the lake, from which a flow issued. There were two
other hot cones in the immediate vicinity which had been thrown up about
three weeks before. On Sunday, Monday and Tuesday following [8, 9, 10],
the surface of the lake rose and fell several times, carrying from full
to the brim to fifteen feet below the edge of the banks.
"On the
morning of the 11th the hill was found to have sunk down to the level of
the other banks, and frequent columns of rising dust indicated that the
banks were falling in. At 9:45 A.M., at which hour a party reached the
lake, a red hot crack from three to six feet wide was found surrounding
the space recently occupied by the hill; the hill was nearly level; the
lake had fallen some fifty feet, and the wall of the lake formed by the
hill was falling in at intervals.
"The lava in
the lake continued to fall steadily, at the rate of about twenty feet an
hour from ten o'clock in the morning, until eight in the evening. At 11
A.M. the area formerly occupied by the hill, began to sink bodily,
leaving a clean line of fracture; the line of this area was continuously
leaning over and falling into the lake. From about noon until eight in
the evening there was scarcely a moment when the crash of the falling
banks was not going on. As the level of the lake sank, the greater h
eight of the banks caused a constantly increasing commotion in the lake
as the banks struck the surface of the molten lava in their fall. A
number of times a section of the bank from two hundred to five hundred
feet long, one hundred and fifty to two hundred feet high, and twenty to
thirty feet thick, would split off from the adjoining rocks, and with a
tremendous roar, amid a blinding cloud of steam, smoke and dust, fall
with an appalling down plunge into the boiling lake, causing great waves
and breakers of fire to dash into the air, and a mighty 'ground swell'
to sweep across the lake dashing against the opposite cliffs like storm
waves upon a lee shore. Most of the falling rocks were immediately
swallowed up by the lake, but when one of the great downfalls referred
to occurred, it would not immediately sink, but would float off across
the lake, a great floating island of rock. At about three o'clock an
island of this character was formed, estimated to be one hundred and
twenty-five feet long, twenty-five feet wide and rising ten to fifteen
feet above the surface of the lake. Shortly after, another great fall
took place, the rock plunging out of sight beneath the fiery waves.
Within a few minutes, however, a portion of it, approximately thirty
feet in diameter, rose up to an elevation of from five to ten feet above
the surface of the lake, the molten lava streaming off its surface,
quickly cooling and looking like a great rose colored robe, changing to
black. These two islands, in the course of an hour, floated out to the
center, and then to the opposite bank. At eight in the evening they had
changed their appearance but slightly. By the next morning they had,
however, disappeared. "About noon the falling lava disclosed the fact
that the small extension at the right of the lake was only eighty feet
deep, and it was soon left high and dry; simply a great shelf in the
bank, high up above the surface of the lake. As the lava fell, most of
the surrounding banks were seen to be slightly over hanging, and as the
lateral support of the molten lava was withdrawn, great slices of the
over-hanging banks on all sides of the lake would suddenly split off and
fall into the lake beneath.
"As these
falls took place the exposed surface, sometimes a hundred feet across
and upwards, would be left red-hot, the break evidently having taken
place on the line of a heat-crack which had extended down into the
lake.
"About six
o'clock the fallen bank adjacent to the hill worked back into a
territory which, below fifty feet from the surface, was all hot and in a
semi-molten condition. From six to eight o'clock the entire surface of
this 61uff, some eight hundred feet in length and over two hundred feet
in height, was a shifting mass of color, varying from the intense light
of molten lava to all the varying shades of rose and red to black, as
the different portions were successively exposed by a fall of rock and
then cooled by exposure to the air. During this period the crash of the
falling banks was incessant. Sometimes a great mass would fall forward
like a wall; at others it would simply collapse and slide down making
red-hot fiery land slides, and again enormous boulders, as big as a
house, singly and in groups, would leap from their fastenings and, all
aglow, chase each other down and leap far out into the lake. The awful
grandeur and terrible magnificence of the scene at this stage are
indescribable. As night came on, and yet hotter recesses were uncovered,
the molten lava which remained in the many caverns leading off through
the banks to other portions of the crater, began to run back and fall
down into the lake beneath, making fiery cascades down the sides of the
bluff. There were five such lava streams at one time.
"The light
from the surface of the lake, the red-hot walls, and the molten streams
lighted up the entire area, bringing out every detail with the utmost
distinctness, and lighted up a tall column of dust and smoke which rose
straight up. During the entire period of the subsidence the lava
fountains upon the surface of the lake continued in action, precisely as
though nothing unusual was taking place.
"Although the
action upon the face of the subsiding area was so terrific, that upon
the portion between the falling face and the outer line of fracture was
so gradual, that an active man could have stood on almost any portion of
it without injury. Enormous cracks, twenty to thirty feet deep, and from
five to ten feet wide, opened in all directions upon its surface, and
the subsidence was more rapid in some spots than in others, but in
almost all cases the progress of action was gradual, although the
shattered and chaotic appearance of the rocks made it look as though
nothing but a tremendous convulsion could have brought it about.
"Another
noticeable incident was the almost entire absence of sulphurous vapors,
no difficulty in breathing being experienced directly to leeward of the
lake.
"At nine
o'clock the next morning the lake was found to have sunk some twenty
feet more: the banks at the right and left of the subsiding area, which
had been the chief points of observation the day before, had disappeared
into the lake for distances varying from twenty-five to one hundred feet
back from the former edge, and the lower half of the debris slope had
been swallowed up in the lake, disclosing the original smooth black wall
of the lake beneath at a considerable overhanging angle.
"At the level
of the lake, and half filled by it, was a great cavern extending in a
southeasterly direction from the lake. The dimensions were apparently
seventy-five feet across and fifteen feet from the surface of the lake
to the roof of the cave.
It could be
looked into from the opposite bank for about fifty feet. This may have
been the duct through which the lava had been drained, although it
manifestly was not at the bot tom of the lake, for up to July 16th,
that had continued to rise and fall from five to ten feet a day, and
constantly threw up fountains, somewhat more actively than before its
subsidence. The entire area of subsidence is estimated to be a little
less than eight acres, about one-half of which fell into the lake.
"While the
break-down was taking place there were many slight tremors of the banks,
generally resulting in the precipitate retreat of the observers from the
edge, but although the danger was great the spectacle was so grand and
fascinating that the party returned again and again to watch it.
"At the
Volcano House two slight earthquakes were felt on the afternoon of the
11th and one vigorous one at 2 A.M. on the 12th. During the week several
slight shocks were felt in the town of Hilo, thirty miles away, yet none
were felt at Olaa, half-way between, nor at Kapapala fifteen miles in
the opposite direction, although the latter is a place peculiarly
susceptible to earthquakes."
Plate 43 is a
ground plan and section of the lake July 30, modified somewhat from the
sketch made by F. S. Dodge in the record book. The thickness of the lava
escaping proves to be three hundred and nineteen feet, and its level
after the collapse six hundred and four feet. The acreage of Halemaumau
is put at 23.67: of the lake 13.65.
Statement of
W. F. Frear. July 24 to August 4 Lake active. "Old Faithful" playing
once or twice a minute, coming up each time as one, two, or three large
bubbles, and then being quiet till the next burst, the other fountains
four to six generally at a time, playing often several minutes before
quieting down. Old Faithful apparently held the same place in March,
1892, for four different days. Three points of special interest.
1. Change in
the height of the lake. This and the place of the walls believed to be
essentially the same after the drop of July 11 and on July 24, but
changed after July 27.
2. Falling of
the walls July 28-29, when the lake fell about fifteen feet. Aug. 2nd
there was more falling, and two days later the lake fell twenty feet
more.
3. New
islands appeared; one having the shape of an angle, flat, with its
greatest length one hundred and thirty feet. Another of oval shape Aug.
4, twenty or thirty feet long, ten or twelve feet high.
This account
is supplementary to the history of the collapse. During the time of the
greatest activity the great heat of the lava made it necessary for
visitors to view the proceedings from Uwekahuna.

The Breakdown
of 1894 as Described by S.
E. Bishop
In the issue
of Nature for September 4, 1902, Dr. S. E. Bishop presents his views of
the changes in Kilauea in 1892-4: The recent destructive eruption in
Martinique has revived interest in the question of the causes of
volcanic action. Only lately have I become sensible of the peculiar
value of some observations of my own as evidence of the primary force
which impels the ascent of lava from its interior habitat, as
distinguished from the explosive violence caused by steam generated by
the encounter of the ascending lava with ocean and other surface waters.
I have long
believed the primary force to reside in the expansion of the gases
originally occluded in the magma, ever since its first condensation from
the nebula. Whenever released from solidifying pressure by disturbances
of the superincumbent crust, the intensely hot magma bursts into a
viscid foam and pushes upwards. In a quiet volcano like our Kilauea,
meeting no water to generate explosive steam, the lava wells up
continuously and steadily in a comparatively gentle fountain, which
displays effervescence only on the surface.
In support of
this opinion I beg to offer positive evidence contained in certain facts
observed by myself in Kilauea during April 8-14, 1892, and on August 28,
1894. The volcano had been in very steady and uniform action for nearly
two years before the earlier date, and so continued until a short time
after the latter date, or nearly five years in all of a quiet,
continuous and rather copious welling up of lava, wholly unattended by
any explosive action.
On the
earlier date I carefully observed the then existing lava-lake during six
successive days. This lake occupied the center of the inner crater,
called Hale-a-mau-mau, or Fernhut. The main crater called Kilauea is
nine miles in circumference, averaging- four hundred feet in depth, and
rather unevenly floored with recent lava. Southwest of the center is the
inner pit of Hale-a-mau-mau. This pit was at that time nearly circular
and 2,400 feet in diameter, with vertical sides averaging one hundred
and fifty feet down to the talus. Before the welling up of lava began in
1890, the pit had been about 700 feet deep. In two years the lava had
risen four hundred feet, and stood within three hundred feet of the rim
and main floor.
A lake of
liquid lava, covered by a thin, spongy film, occupied the center of the
pit. This lake was nearly circular, averaging 850 feet in diameter. It
was bordered by a low dyke, which partially restrained its frequent
overflows. Outside the dyke, freshly congealed lava sloped away to the
talus. By day the crust-film was grey to the eye, but by night a deep
red. It was traversed by numerous fissures of white fire. During the
whole time three fountains of lava were welling up with somewhat regular
intermittence, and three smaller ones at irregular intervals. There was
no explosive action whatever.
The largest
fountain was about one hundred and twenty feet southeast of the center
of the lake. It played with great regularity about three times in a
minute, rising in a round billow twenty-five feet high and fifty feet in
diameter, bursting at the top and falling back to level, its discharge
moving in a broad stream towards the center of the lake. The fling of
spray from its summit rose to forty or fifty feet above the level.
West of this
central fountain were two others of very different character, being more
spasmodic in activity, but never long quiet. Occasionally they would
unite their forces for half an hour at a time, forming a stationary line
of one hundred and thirty feet of spraying billow much like a
surf-comber with flying spray. This stationary surf -wave was fifteen
feet high, incessantly flinging its spray ten feet higher along its
whole length. In the night, the effect of these fountains was extremely
brilliant and was attended by loud metallic crashing.
The other
three fountains were smaller, near the borders of the lake, and often
quiet for hours together.
During the
thirty months' interval between my two visits, the gradual elevation of
the fire-lake continued quite uniformly, as attested by occasional
photographs. By its frequent overflows it had built itself up to a
height of fully fifty feet above the previous main floor of Kilauea, so
that it formed an extremely low truncated cone, surmounted by the level
lake, to the edge of which visitors daily approached.
About March,
1894, a recession began, which ended in a final collapse of activity.
The lake soon sank some hundreds of feet, carrying with it the sides of
a circular pit, about 1,400 feet in diameter, and central to the
original 2,400-foot pit. When I saw it in the following September, the
fire-lake was not less than five hundred feet below the rim. During the
evening, masses of rock frequently crashed in, driving heavy surges of
fire far up the talus. There was a good deal of steam-cloud slowly
rising, charged with sulphur. During my previous visit, all vapour had
seemed to be absent, and I made the circuit of the pit without
encountering sulphur. Subsequent photographs had also indicated the
absence of vapor from the lake.
I now have to
add an important observation. To my great surprise, at this last visit,
I perceived that the three fountains above described were in full
activity and in the same relative position as before, although during
the thirty months the level of the lake had risen three hundred and
fifty feet and had then fallen five hundred feet. By what system of
supply-ducts such fountains had been so long maintained was a mystery
concealed in the fire-depths. But the fact of a marvelous steadiness and
uniformity of action was obvious. For a long period a uniform and gentle
outpour of effervescence had been maintained. It has persisted for two
years and a half, throughout all the immense changes.
I submit as
the unavoidable conclusion that the source of supply for this five
years' outpour of gently effervescing lava was in an interior magma
which itself contained the impelling force in its own originally
occluded gases. For its activity this source was wholly independent of
any encounter with water to generate steam. Expanding steam evidently
had no part in that steady, quiet, persistent activity in the fire-lake
of Kilauea. I would add that the exceptionally quiet and uniform
activity of Kilauea seems to render it one of the most important of all
volcanoes for study. I regret to say that since the collapse nearly
eight years ago no lava has appeared in the crater, except a small
quantity last June, which has again gone out of sight.

March 26,
1899 the Hon. L. A. Thurston writes, the outer rim of the pit is the
same as that figured in 1894, being by estimate eight hundred feet deep,
one hundred and fifty feet in diameter at the bottom. A pit formed March
24th, in which no bottom can be seen. There is a steep vertical wall on
the north side for three hundred feet down. On the south side the
vertical wall extends about six hundred feet down, before coming to the
debris. At the opening of March 24th a loud noise was heard; a great
cloud of dust arouse, produced probably by a slide.
Prior to the
filling of the pit a dense cloud of smoke was pouring out of it. It
ceased almost entirely after the slide. The heat-crack parallel with and
four hundred feet distant from the north wall of Halemaumau has greatly
increased in heat since December last when I last saw it. It is sizzling
hot a foot back from the edge and shows a cherry red about twenty feet
down. This is the first fire seen in the crater since June 24, 1897.
In June and
July, 1899, I inspected the pit and its surroundings. Because of a
constant dense cloud of steam and vapors the bottom could not be seen.
In an opening a short distance to the north of the pit, it was possible
to descend and observe the formation of small stalactites and
incrustations of gypsum in a temperature suggestive of 140° F.; and an
eighth of a mile farther northerly was a larger similar opening, though
less hot. Paper could easily be ignited in cracks nearby.

Conditions in
1902 and Later
After a long
season of quiet, slight activity is resumed. Hon. L. A. Thurston writes
in the Record Book of the Volcano House, February 14th, as follows:
The outlines
of the pit of Halemaumau are essentially the same as when last reported
(1900). Very little sulphur vapor arises from two or three spots on the
north and east sides. There is a clearly defined recent flow of black
lava at the extreme bottom of the pit, the first in several years. The
heat crack on the north side is hotter than ever before.
The same
writes June 12:
The debris on
the north side of the pit has dropped down. Dense sulphur vapor rises
from the extreme bottom of the pit and fills it so completely that
nothing can be seen for much of the time. Two hundred feet from the
bottom of the east side there is a bright light, seemingly emanating
from fresh lava in a cave.
The lava seen
February 14th has been covered by debris. Apparently the action in the
pit is the beginning of its filling- up. Steam still rises from the big
cracks running from Keanakakoi towards Kau, although they are nearly
filled with drift sand and pumice stone.
August 25, 10
P.M. Mr. Waldron says a lake four hundred feet in diameter has just
formed in the bottom of Halemaumau on the Kau side. It has the shape of
an irregular quadrilateral. There was no earthquake here, but there were
shocks at Hilo at 11:45 P.M., August 24th; at 3 P.M. the 25th and
3:15A.M. the 26th.
September 12
Hon. L. A. Thurston says: The new lake has subsided leaving a black
ledge one hundred to one hundred and fifty feet above the present
bottom. From this ledge down to the bottom it is black with new lava.
There is a sulphur steam jet on the west side. No fire is visible in the
daytime, but it can be seen at night. Later in the day there was a heavy
breakdown of the western wall, causing the rise of a great cloud of
reddish vapor.
Sept. 17 T.
M. Chatard says that on the night of the 15th instant there were a
number of fire fountains; the hardened crust broke and dissolved, while
the lava flows were large enough to show the manner of action.
Whitman
Cross, of the United States Geological Survey, has put on record at the
Volcano House the behavior of Halemaumau between October 20th and 27th.
"On Monday, the 20th instant, there were almost no signs of activity.
The lava flow produced by earlier action was recognizable. With a tape
line parallel tangents to the circular outline of the crater were drawn,
which were 1,500 feet apart, representing the diameter. The depth to the
consolidated lava was estimated to be eight hundred and twenty-five
feet; and the north-south diameter of the same w::ts five hundred and
seventy-five feet. The vertical wall on the south was deeper than upon
the opposite side, while in the first case there was a gradual slope to
the lava floor, on the other side the slope was higher up and connected
two walls. On the north edge of the lake there was a blow hole or
spatter cone about twelve feet high exhibiting two small glowing spots,
and sulphurous fumes arose from the cone without noise. October 23d
there was a sound of escaping gas from the blow hole, like the sharp
puffs of a locomotive getting under headway; they were irregular though
often strenuous. At 3 P.M. a part of the top of the cone was blown off,
followed by the sound of thrashing and surging lava. At every throb
splashes of lava were thrown out of the orifice and the cone grew
rapidly. At 3:35 P.M. the whole northwest side of the mound was broken
down and a torrent of lava burst out like water from a pipe. The flow
was steady with occasional spurts throwing small masses a few feet into
the air.
"The lava was
liquid, red-hot changing to dull red and black as the crust formed, and
as it spread out the domes and ropy lines so characteristic of the
general floor of Kilauea made their appearance. By 5 P. M. the flow had
covered half of the floor. At 7 P.M. the whole floor was covered and the
liquid still continued to gush out; then it decreased and new spatter
cones were built up, with orifices by 9 P.M., from which jets of lava
were occasionally thrown out.
"The new lava
lake exhibited during this evening the common phenomena so often
described. Cracks formed in the dull crust, lava pushed out in sheets or
tongues, plates of the crust turned up and sunk in the molten lake
beneath. The illumination was often brilliant, and all the conditions
combined to make the scene grand and impressive. On October 24th there
was no flow; the floor was so solidified that fracturing and extrusion
of lava was rare and of small extent. At the blow hole there was
frequently repeated the process of sealing up the orifice by viscous
matter, then a bursting out, making a new hole, which would be sealed up
again in an hour or two."
"On the
evening of the 25th the strong glow indicated action, and there was
another thin flow over the sheet of the 23d. The spatter cone remained
on the north side and no other vent could be seen. The action was that
of sealing up and bursting again, without any discharge. On the 27th
just before daylight a bright glow was noted over Halemaumau, which was
occasioned by another thin flow."
The three
flows recorded built up the inside mass, perhaps twenty-five feet. He
supposes the process of filling up Halemaumau will be continued in a
similar manner, unless relief be found by an outbreak of the lava at
some lower level, as h:qs often been the case in the past history of the
volcano.
In the
Hawaiian Gazette for November 18th, appears a further report of the
display for a week commencing November 7th.
Friday,
November 7 Cone spitting fire only; no flow. Saturday and Sunday: 1'\o
change.
Monday,
November 10: At 2 A. M fountain commenced to play.
Tuesday
Today the action is stronger than it has been during the present
outbreak; cone blown to pieces, and a geyser spout ing fire twenty feet
high and about as wide, forming a lake from bank to bank of liquid lava,
which is about six hundred feet across: this action continued all day
and night.
Wednesday and
Thursday, November 12, 13 The action continues as strong as ever,
building up the lava lake very rapidly. The lowest floor of the pit has
risen one hundred feet since October 20. These were wireless messages
from the Volcano House to Mr. Richard Trent.
In the same
issue a diagram is given representing the dimensions of the pit, and the
amount of the filling since June 1st. The breadth of the pit, 1,500
feet. Depth, June 1, 1,000 feet. Level of the lava October 20, one
hundred and seventy-five feet above the bottom. November 13, level of
the lava two hundred and seventy-five feet above the bottom, seven
hundred and twenty five feet below the surface of Halemaumau.
From Thrum's
Annual for 1903, the report for 1902 is confirmatory of the preceding
statements. On the evening of August 25th, lava suddenly appeared in the
pit, accompanied by earthquakes of nearly the same date at Hilo. Then it
was quiet till September 19th. Another manifestation showed itself
October 11th. Measurements proved that the lava had risen one hundred
and seventy-five feet since June; the pit in September being eight
hundred and sixty feet in depth and about two hundred across.
On the night
of October 23rd three, and occasionally, four fountains of lava spouted
up from below. November 10th the entire floor of Halemaumau was a mass
of molten lava throwing up geyser-like streams.
The Hawaiian
Star of March 13, 1903, prints an anonymous statement that there was a
manifestation of molten lava about fifty feet wide in the bottom of
Halemaumau.
June 21, 1903
Hon. W. R. Castle states that the conditions were very much the same
that he saw in 1874, except a filling up by fresh lava for about three
hundred feet. Total depth estimated to be seven hundred and fifty to
eight hundred feet. He adds: "The time has come when the United States
Government might well reserve the whole region of Mokuaweoweo to the sea
at Puna; a long narrow strip to include Kilauea and the line of pit
craters; a comparatively worthless tract of country commercially. It
should also include the Koa tree moulds at Kuapaa wela, where a forest
of giant trees was surrounded by a deep flow of later age."
August 23
Clouds of smoke are ascending from the pit. Following this date all was
quiet for a long time.
November 25
Halemaumau is in action. There was a glow at 4:15 A.M., when a lake
formed, forty by one hundred and twenty-five feet, in the bottom of the
crater. Fountains of fire showed themselves, and the other phenomena
customarily observable in their company. Remained active till Jan. 10,
1904.
In 1903 a new
survey of Kilauea was made under the auspices of the Bishop Museum. A
relief of the volcano upon the scale of one hundred and thirty feet to
the inch has been prepared by William Alanson Bryan and placed on
exhibition. It is the most effective illustration of the volcano ever
displayed; and it is understood that the earlier survey of Dr. Brigham
in 1865 was found to be accurate. The explanatory text represents that
the complete area of Kilauea as portrayed in the relief amounts to 2,650
acres; the circumference 7.85 miles; extreme length 15,500 feet or 2.93
miles. The most noticeable change in the representation is the emphatic
manifestation of a greater altitude to the east of Kilauea iki. All
previous restorations have made the land to fall off towards the sea (makai).
The exact figures are not given save as they are embodied in the model.
August 13-17,
1904 Professor G. H. Barton visited the volcano with a company of
tourists, and compares the present state of inactivity with the
brilliant displays he had seen twenty-two years earlier.
1904 Hon.
L.A. Thurston writes thus November 8th: There have been only slight
changes since September 12, 1902. Cracks along the outer rim of the pit
have widened, and the approaches seem more dangerous than ever before.
No fire nor steam appears in the pit, but there is a considerable
sulphur vapor from the extreme bottom. A new path has been made around
Kilauea iki for which he suggests the name Echo trail for five
distinct echoes can be heard from the west bank of Keanakakoi.

The
Displays in 1905
New interest
has been manifested in Kilauea in 1905 because of renewed activity. At
the opening of the year Halemaumau was a lifeless pit over eight hundred
feet deep, whose floor consisted of the cooled overflows, last seen
November 25, 1903.
February 24th
fresh lava appeared on one side near the bottom, flowing down to the
lowest point. After four days of display it was covered up by a slide of
debris. Fire was again seen March 3rd and March 20th. On March 30th
several fiery spots were reported. April r8th, at the depth of six
hundred and fifty feet, there was special activity; fountains were
playing continually accompanied by large volumes of red-hot lava.
May 1, 1905
L.A. Thurston. A blow hole on the north side has flowed out over the
bottom of the pit, making a platform five hundred feet in diameter. It
was exploding at intervals of several minutes throwing spatter lava
thirty to forty feet. The pit has filled a considerable since November,
being now five to six hundred feet deep. The southern bank continues to
fall in.
The history
for the ensuing four months has been an alternation of fiery discharges
and a cooling surface. July 24th to 26th, the depth of the pit was
estimated by myself to be about six hundred feet. About every third
night the displays of fire are exceptionally brilliant. The place of the
discharge shifts constantly from one edge to another. Those that I saw
were on the north, west and south edges. The latest report given to me
was of a brilliant display on the nights of August 12th and 13th.
Sept. 18,
1905 L. A. Thurston. Very little change since May 1, except that the
pit has filled a little more and the vapor has increased, rising from
two cones on the northeast side of the pit. No fire visible nor noise
heard in the pit. Bank on south west side has caved in considerably
since May. Smoke very dense, light brown in color, with very little
sulphur.
I find in the
Hawaiian Gazette for March 13, 1906, the following:
The fires of
Kilauea are still in evidence (by wireless telegraph). Volcano House,
March 12. Last night our party sat on the edge of Kilauea, fascinated by
the display of fire which burned for hours. Mr. and Mrs. Waddell, Edna
Lloyd.
Dec. 2, 1906
fire appears in Halemaumau. E. D. Baldwin reports two small lakes,
mostly cooled over, the one six hundred and two and the other five
hundred and ninety-seven feet below the edge of the pit. Near the center
of the western lake a small cone sputtered lava occasionally, with loud
reports of escaping steam, which at times sounded like rifle shots. The
surface would crack, and considerable lava flow out. The action in the
east lake was much the same. There was no sputtering cone, but steam
escaped under the east bank with noisy outbursts. The smaller spot to
the south is nearly cool.

Kilauea in
1907
Jan. 27,
1907, F. S. Dodge reports that the lava had filled up the pit to the
level of four hundred and fifty feet from the top, occupying an area of
nine acres. Plate 44B is copied from a plan made by E. D. Baldwin, Dec.
26, 1906, showing the appearances then visible, and the relative
positions of Halemaumau in 1886, 1892 and I906. And upon one side the
pit of Dec. 2, with its two lakes, the filling up to four hundred and
fifty feet, Jan. 27, 1907, and up to one hundred and ninety feet as seen
July 26, I908.
Hon. L. A.
Thurston spent a month in Hawaii, and under date of April 23, reports as
follows in the Hawaiian Gazette concerning the volcano:
I visited the
crater three times. It is more active than it has been at any time since
the formation of the present pit in July, 1894. The pit has filled to
within about three hundred and fifty feet of the top. There is a molten
lake about four hundred feet long by two hundred feet wide. During the
interval between 11 A.M. and 3 P.M. one day, about ten days ago, this
lake overflowed its banks bodily, three times, the congealed lava crust
being swept over the banks in a crimson flood, the surface of the lake
rising and overflowing in a mass approximately one hundred feet wide. In
addition to this there were from two to ten molten lava flows
continuously issuing from the banks and flowing to the lower portion of
the pit. At the present rate of filling, the Halemaumau pit, which was
nearly a thousand feet deep three years ago, will be filled within the
year, and the condition which existed in 1894, a molten lake higher than
the surrounding country, will be repeated.
May 21st and
22nd, the volcano was inspected by the Congressional party which visited
the Islands under the auspices of the Territorial Government.
Twenty-eight members of Congress with their friends had accepted the
hospitalities of the islands. Pele was in one of her quiescent moods,
but the scene was impressive and grand enough to satisfy their
anticipations. A novel experience consisted in the serving of a dinner
to the visitors where toothsome viands had been cooked by the heat
supplied from the depths. After the dinner the health of Madame Pele was
proposed by Hon. L. A. Thurston, who recited the legend and described
the varied vagaries of the volcano. The numerous citations in this book
from Mr. Thurston's statements prove that no one could better narrate
the history of the volcano than he.
May 28
Demosthenes Lycurgus reports signs of fire, which increased by July 10
to be a lake of fire boiling furiously seventy-five by seventy-five
feet. It rose over the pit floor and flowed down in a cataract.
Continued to rise and fall every twenty-five minutes.
July 12 F.
M. Wetmore saw two lava flows, three active fountains and a cone sending

Fire in three-fourths of the pit of Halemaumau. Eight large fountains.
Mr. C. L.
Rhodes has described very graphically what he saw August 13 to 15. The
molten lava has accumulated in the large pit from one thousand to about
one hundred and fifty feet below the rim, a liquid conical column,
broadest at the base. The fountain of supply is from Old Faithful, a
small area near the north side. About a third of the surface is never
blackened over. This lava has been building up a wall around itself,
which on the 13th inst. was fifteen feet higher than the outer zone of
the liquid, so that the lake might be compared to an inverted saucer. At
length the lateral pressure overcame the strength of the wall, and the
lava flowed out in great streams until it tended to even up the surface.
The lava may sometimes be higher at its border than it is nearer the
center. Plate 46 shows a rough plan and photograph of the lava, as seen
in August.
August 18
N. B. Emerson. The fire-pit bounded by a vertical wall two hundred feet
high; I,000-1,200 feet in diameter. Fire-lake occupies from one-half to
two-thirds of the pit, bordered by a sloping black ledge between it and
the walls. Lake usually covered by scales of dark lava traversed by many
fire lines, not clear cut, but jagged like fish bones. Fire Fountains.
"Old Faithful" described. A jet of red lava appears; scales are sucked
down around it. This swells up as one huge rotund white hot mass leaping
high up into the air for many seconds, and then subsides as if there
were a connection with a fire-shaft deep into the earth's interior. This
is in the northeast part of the lake. There are others in the northern
quarter and near the edge, never so large as Old Faithful. Fire-lines
suggest the arms of Octopus. Firecaves or ovens on the west side.
Action like surf breaking upon the side of a cliff, somewhat rythmic.
Movement from west to east. In 1881 there were three fire-lakes and a
correspondingly greater action.
August 20
W. D. Alexander had seen Halemaumau when it was an abyss 1,000 feet deep
and 1,200 feet wide, pouring out volumes of black smoke; now there is
the breaking down of the retaining walls of the inner lake in three
places from which cascades of liquid fire are falling and flowing till
the whole space is filled up to the level of the inner lake.
Aug. 26 to
Sept. 6 Condition described by Dr. W. T. Brigham in Thrum's Annual for
1909. The present floor of Kilauea is now about four hundred feet higher
than in 1864. The Halemaumau pit had filled up to within one hundred
feet of the rim or fifty feet above the lower edge of the dome.
Thursday,
Sept. 4 in the early afternoon the fountains ceased to play and the
subsidence of the pool began. With Messrs. C. B. Thompson and C. N.
Forbes, Dr. Brigham went to Halemaumau soon after dark and found that
the lake had fallen about a hundred feet. "In the center of the pit was
a curious break running E. to W., at the edge of which was a vertical
slab of lava semi-circular in form, resembling half a millstone, and
other slabs continued the wall for some distance. Over these fell a
cascade of lava in a condition I had never seen before; its particles
seemed to be in a state of repulsion, and although white hot fell
through the central hole of the 'mill-stone' as meal. There seemed
absolutely no cohesion, no signs of plastic molten lava."
Mr. G. H.
Fairchild describes the collapse as follows, the whole process of the
emptying taking about two hours time. "On Thursday night the level of
the lava had reached a point less than a hundred feet, I should judge,
below the level of the main crater floor. Old Faithful spouted its fiery
flow to a height of twenty feet, and from the edges of the lake a score
of lesser fire-fountains were playing continuously. At midnight there
was a strange motion in the lava, which began suddenly to sink in
towards the center. The sinking continued till the whole pit was a
maelstrom of fire and a chasm appeared in the lava lake. Like liquid
pouring into a funnel, or like the waters swirling out of a bath tub
after the plug is drawn, the boiling lava began to pour in cataracts of
fire into the chasm. From all sides the lava flowed, and as the torrents
drained away into the depths, the sides of the crater, gleaming red,
began to crash into the lake, splashing the lava like surf into the air,
while the dull roar of the crumbling rock and the sharper detonation as
the colder rocks heated and exploded was terrifying but yet absorbing.
"As the great
slabs of lava peeled off the sides, pieces hundreds and thousands of
tons at a time, the levels streamed out cascades of liquid lava, which
hung and cooled about the sides like great golden stalactites. Deeper
and deeper the lava sucked into the depths and on Saturday morning the
pit was dead. Everything that had filled it with the bubbling, spurting
lava for nearly a thousand feet had drained off in the opening far below
and there was nothing to be seen in the depths of Halemaumau but a cloud
of smoke. All the fire had gone."
Sept. 6, at
11 P.M., a spark of fire appeared five hundred feet down, and lava
'increased for two hours, when the lake was only one hundred and fifty
feet lower than before the collapse. J. A. Kennedy. "The fire increased
very rapidly, astonishingly so. It spread in area, and so quickly that
we could see it was rising, apparently being forced up by some great
power beneath. This force seemed to push the lava into a cone that would
burst with a noise, shooting the flame higher and higher. It continued
in this way, the fire coming nearer and the cones forming and bursting
one after another. There appeared at one time to be three cones of fire
that merged into one; and again, when the force beneath must have been
more intense the flame shot fully two hundred feet into the air like a
rocket, then gradually spread out into the shape of a fan
L. A.
Thurston writes, "The lava was rising rapidly. All at once it quit
rising. A red line showed around the border; masses of cooled lava broke
off and fell into the liquid. These falls and rises vary from ten to
fifty feet. There is an artesian flow on one side. When the lava lake is
low a stream comes from this orifice. When the lava rises above this
stream it becomes a fountain pushing upwards."
There was an
earthquake at Hilo and in Puna about noon of Sept. 2. Another at 6:15
P.M., Sept. 4. A third, at 6:15 P.M. Sept. 5, the most severe of all.
Sept. 6 a slight one. The shocks were unusually severe. Those who
experienced the shakeup of 1868 believed these were equal to those.
Great damage was done in Hilo to china and earthenware. The shocks were
heavier in Puna than in Hilo.
The near
coincidence of these earthquakes with the first discharge of the lava
from Halemaumau leads us to believe that the two phenomena were
genetically connected with each other, rather than to some general
cosmic influence.
Oct. 2 to 11
E. E. Paxton reports that the lava was rising in Halemaumau when he
left; it had risen fifty feet during his visit; and is from one hundred
and fifty to two hundred feet below the top.
W. A. Bryan,
Sept. 17 The lake estimated to be nine hundred feet across with
fourteen fountains. Liquid lava thrown up two hundred and fifty feet,
even above the border of the pit. In October, '02, he had found the lake
to be five hundred and twenty-five feet below the surface. Since then
there have been landslides in Kilauea. Along the eastern side the old
observation point has disappeared. A strip of rock sixty feet long caved
in a few days after his model of the volcano had been completed.
Oct. 17
Harry Dennison measured the depth of the lake with a string. Two hundred
and twenty feet were recorded, and he estimated the balance of the
distance at from fifty to one hundred feet.
Oct. 18 Old
Faithful was active eighteen times in ten minutes. On the 21st it was
twelve times in ten minutes; and again eighteen times in ten minutes.

Kilauea in
December, 1908
The
conditions at Kilauea in the early part of December were examined by
myself in company with Mr. Thurston, who writes as follows, under date
of Dec. 6:
"No radical
change since last September and October. The surface has subsided
somewhat, being now three hundred feet deep. No indication of rising or
falling seen. The welling of the lava as voluminous as ever. Action less
spectacular than in September. Chief action on northwest side, where
there was continuous boiling over an area one hundred by one hundred and
fifty feet; lava being spattered up ten to twenty-five feet. A
tremendous suction adjacent to the boiling area, moving as much as five
miles an hour. Three black ledges, the innermost from fifty to sixty
feet high."
There was no
change in conditions from Dec. 3 to 11. The length of the lake was
estimated to be three hundred and fifty feet and half as wide.
Occasionally the lava would flow in from a hole on the northerly side.
Much of the surface was darker because of its congelation; thus various
fire lines would make a network, the pieces would be disjointed and sink
out of sight. The spatter work reminded one of gold leaf. Except that
the level of the lake was lower than it was early in September there was
no essential change in the conditions, as described above. Pele's hair
was plenty.
The general
features of the Caldera may be mentioned. A carriage road has been
constructed from the Volcano House to the south side of Kilauea-iki, a
distance of four miles. The government has furnished a number of
convicts from the penitentiary who are engaged in the necessary digging,
grading and removal of the earth. It is intended that this road shall
soon be completed as far as to Keanakakoi, and thence directly to
Halemaumau across the sulphur banks, so that visitors may ride in
carriages to the very brink of the fire; and eventually it will be
possible to ride entirely around the Caldera. It is evident that there
have been several slides of rock into the pit, so that the area of the
volcano is constantly growing larger, though not enough to be noticeable
upon our maps of small scale.
A few
altitudes are presented:
Viewed from
above the black rock is very suggestive of ink. On reaching the floor
the roughnesses are seen at their proper dimensions, comparable to waves
on the ocean. A well-marked trail leads to Halemaumau, traversed
constantly by tourists on foot or horseback. Quite near the starting
point is a large fissure spanned by a bridge, as much as a fourth of a
mile in length, crossing the path and rudely parallel to the north wall.
To the left are many hollow domes from one to three hundred feet long
and perhaps twenty feet high, lined with stalactites. These were once
liquid lava flowing northerly from Halemaumau. These hummocks and the
whole surface are traversed by fissures, produced by the falling of the
roofs of these tunnels, and often these clefts have been occupied by
streams of lava. The floor is an immense black ledge, mostly pahoehoe,
and having much ropy structure. Next the east wall the waves are
smoother and broader. The flow from Poli-o-Keawe of 1832 is hardly
recognizable, having suffered from slides, and also has been obscured by
vegetation. Rather towards Uwekahuna are black lines of aa. Near the
corral for horses may be seen the flow of the Little Beggar, a sunken
tunnel with five flows of petrified lava, films and incrustations of
gypsum. To the west are areas from which hot gases arise, as the Devil's
Kitchen, where food may be cooked and postal cards scorched. Near the
view point of the melted lava are the remnants of three spiracles.
Halemaumau is surrounded by the finest exhibitions of the domes,
tunnels, and ropy structure, being largely the flow of 1894.
The guides
can find caves filled with stalactites to the south, where fine
specimens may be obtained. There are also places where sulphur has been
condensed from the vapors. When the lava was fresh there were various
grades of liquidity; the thinnest being where the heat was most intense,
and the surface had a beautiful black glaze, sometimes called
hyalophane.
The sulphur
banks in the southwest part of the Caldera seem to consist of tuff
dipping gently towards Halemaumau. There are several rents upon it
running N. E. and S. W., seemingly the work of recent faulting. Steam
rises after rains, from the east side of Kilauea between the sulphur
banks and the 1832 flow. The basalts succeed the tuffs at the mouth of
the canyon leading from Keanakakoi, with a horizontal stratification. A
similar consolidated tuff borders the volcano opposite Halemaumau, and
Puu Pohaku is covered by much basaltic pumice.
Early in
February, 1909, E. D. Baldwin finds the level of the liquid lava to be
two hundred and thirty-five feet below the edge of Halemaumau.
Back to Contents
Halemaumau
Halemaumau is
always the place where the fire is to be seen. It might be called the
core or nucleus of the volcano. While the pools of lava may appear
elsewhere when the discharges are profuse, the fire will be seen only at
the bottom of the pit when it is nearly extinct. The number of the lakes
is variable'. When it exceeds unity it is not easy to select the
particular one which represents the chief avenue of the flow. As a
matter of convenience I will present a resume of the history of these
lakes of molten lava. The earliest account is rather indefinite. In 1825

Is Halemaumau
a Fixture?
Mr. A. B.
Loebenstein of Hilo is reported in the Washington Post of Feb. 6, 1906,
as saying that Halemaumau has moved south 1,783 feet during the past
thirty years. In 1873 when surveys were made in connection with the
leasing of the land, this crater stood within the area of Keauhou, the
boundary line passing through its center. Thirty years later a new
survey was made which proved that the floor of the crater had crossed
the boundary line into Kapapala. "It should be understood," he says,
"that the inner crater of Halemaumau has not disappeared in one place
and broken out in a new spot, but that it has worked itself along the
floor of the outer crater foot by foot for a third of a mile."
These remarks
were made in connection with a suggestion that the Government should
take possession of the volcano and its surroundings for a National Park.
Incidentally it may be a question of ownership, and concerning that we
have the reported remarks of Mr. F. S. Dodge, Superintendent of the
Bishop estate.
"The shifting
of the lake of fire does not invalidate any claim we may have on it. The
line of the Bishop estate is tied to the center of the lake, and our
boundaries move along with it. The description of the boundary shows
that the line runs from well-known points on the bluff 'to the center of
the lake of fire,' and it is a well-recognized fact in the Territorial
Courts that a recognizable fixed point has precedence over distances and
bearings. Thus, no matter where the lake of fire may wander to, it drags
our line along with it."

Houses of Entertainment for
Visitors
The first one
mentioned was situated upon the Malden plateau in 1824, for the
accommodation of the Princess Kapiolani and her retinue. It was a simple
native hut, and was found to be very convenient for the use of Lord
Byron's party in 1825.
In 1840
Captain Wilkes' party encamped upon the low ground between the sulphur
banks and the volcano. Mr. Goodale says that in 1847 he slept in an old
shed; in 1856 he found a house but no host. Other early visitors
represent this place of accommodation as a grass house consisting of one
room with a coarse hala mat upon the earth floor. Travelers brought
their provisions and used for drink the water that was condensed from
steam. In Plate 47AB may be seen
two of
the early houses,
perhaps in
1868 and 1872,
supposed to
be situated upon the
site of
the present
Volcano House. In 1865
this house
had become
sufficiently durable to allow the
keeping of a record
book. About this time the
industry of gathering the pulu
from the tree
ferns to
be used
as the filling of
mattresses was quite
flourishing, and the
house accommodated both
the visitors and the pulu gatherers. Judge L. Kaina and G.
W. C.
Jones were associated together in
this business
in the
sixties and
seventies, and
the house
seems to
have been of
this primitive
character.
Upon June 6,
1877, W. H. Lentz was employed
to assist in building a
better house,
using boards
and timbers. He
succeeded to the position of
landlord and remained in charge
till April, 1883. Messrs. Jordan and Shipman were in charge for the next two
years. June 20, 1885, the property passed
into the
hands of the
Wilder Steamship Company,
with J. H. Maby for manager.
There was a
new organization
April 1, 1891,
called the
Volcano House Company: W.
R. Castle, president;
Peter Lee, manager. Extensive
additions were made to
the house. In 1901
there were further additions
to the buildings.
Fred Waldron
succeeded Mr.
Lee as
manager.
St.
Clair Bidgood
was the
manager in 1903.
George
Lycurgus was next elected
manager, succeeded at the end
of 1904
by Demosthenes
Lycurgus, the
present head, who is also
the chief
owner of
the stock
of the
company.

appears today.
