"While the break-down was taking place there were many slight tremors of the banks, generally resulting in the precipi tate 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. 1\I. 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 3o, 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 Hale maumau 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, com ing 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 quiet ing 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 II 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. 2 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.
