96 L. L. Van Slyke—Kilauea after the Eruption of 1886. 
400 to 1000 feet, there rises a very steep hill of loose rocks, 
perhaps 150 feet high, the base of which extends from the west 
wall in a rather direct line to the “Peninsula,” or farther. Thus, 
between the wall around the pit and this hill of loose rocks, 
there is a deep trough-like depression. At the “Smoke Jet,” 
near “‘ Halema’uma’u W ” the height of this hill of loose rocks 
suddenly drops to perhaps 30 feet, at which height the hill 
continues to the nearest point in the west wall. The ‘Smoke 
Jet” is located in the side of the hill just where the height 
drops down. This hill was found to extend on farther, being 
more or less clearly defined all the way around, so as to form 
really an immense cone with an oval or irregularly elongated 
base. This immense cone covers the site occupied by the deep 
central pit described by Mr. Emerson, as far as I can determine, 
—indicating that a general upheaval or rise of material had 
taken place in this part; for instead of a pit in the shape of an 
inverted cone there had appeared on its site an upright cone of 
lava rocks. ‘The bottom of ‘‘ New Lake” appeared to be cov- 
ered with loose rocks. I did not explore this part at all care- 
fully. 
Molten lava was visible in three different places. Two of 
these were deep holes or wells, the other a “lake,” covering 
perhaps five acres. I will describe these in the order in which 
I visited them. 
Starting at a point between ‘Little Beggar” and. “ New 
Lake 1,” I crossed the sunken ‘“ Bridge,” and ‘went, in vearly a 
str aight line, toward the center of Halema’uma’u. For a little 
distance the route was down a moderate grade, but later it 
became very steep, when I came to the base of the cone of loose 
stones just described. The passage was over large slabs of 
pahoehoe such as Mr. Emerson describes. Ascending the cone 
part way, I came to the edge of a deep hole or well, of rather 
irregular outline, four-sided, perhaps 30 or 40 feet ‘wide, and 
from 60 to 75 feet long, and not less than 100 feet deep. The 
mouth was surrounded by masses of loose rocks, rendering 
approach to the edge impossible or yey, 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 eommotion, attended by a peculiar swashing noise, 
but I could not lean sufficiently far over with safety to see any-
