FS. Dodge—Kilauea after the Eruption of 1886. 99 
Halema’uma’u pit, and later observations taken froin the same 
station and under similar circumstances, showed that the hills 
were rising at the rate of nearly one foot per day... . 
Having exhausted my supply of flags, I continued my walk 
along the eastern side, examining the ground carefully for proper 
locations for new stations, and visiting the very interesting 
small craters of Kilauea [ki and Keanakakoi. The former is 
about 3800 feet in length from east to west, and 2800 feet 
from north to south, with regularly sloping walls, completely 
covered with a dense growth of small Ohia trees, ferns, etc. 
In March last, at the time of the disturbance in Kilauea, a land- 
slide occurred on the northeast side of Kilauea Iki, leaving the 
face of the cliff bare from top to bottom, and showing all the 
strata distinctly. The depth of this crater was found to be 749 
feet from the point at the end of the path from the Volcano 
House, or 867 feet below the Volcano House veranda—which 
has been taken as a datum for all elevations connected with 
Kilauea.

Keanakakoi is 1600 feet in length and 1100 in width and 
approximately 400 feet in depth, with almost vertical walls, 
bare of vegetation, and a very smooth floor of pahoehoe. 
From careful study of Mr. Hmerson’s map, and from obser- 
vations made during five visits to the locality, I conclude that 
there has been no change in the ‘‘ New Lake” depression, or in 
the “ Bridge” between that and Halema’uma’u, and very little
