448 J. D. Dana—LHistory of the Changes in Kilauea. 
May, 1838, about six years after the eruption, Captains Chase 
and Parker were at Kilauea. An account of what they saw 
was written by Mr. EH. G. Kelley from their statements, sub- 
mitted to them for approval, and afterward published in this 
Journal (X), with a plate from their sketches, but redrawn un- 
fortunately by a New Haven artist who evidently had Vesuvius 
in his thoughts. _An outline copy is here introduced. It was 
taken at the south end looking northeastward, and has the Great 
South Lake in the foreground. There is no black ledge on the 
west or north side; and to the left instead of a black ledge there 
isa depressed plain, 40 feet below the general level; the part of 
it AA was flooded by lavas after having been passed over by 
the party. The crater was unusually active; there were 26 
volcanic cones, 20 to 60 feet high, eight of them throwing out 
cinders, red hot lava and steam, and six lakes of lava (c), in- 
cluding the Great Lake ‘“ occupying more space than all the 
rest.” 
Not far from the center of the Great Lake there was an island, 
I, of black solid lava which “ heaved up and down in the liquid 
mass” and ‘rocked like a ship on a stormy sea.’’ This is 
the first mention of a ‘floating island.” The descending 
streams at B are described as streams of sulphur, but as this is 
not possible they were probably lava-streams in part colored _ 
ellow. 
‘ The same year, in August or September, Count Strzelecki 
(who later visited New South Wales), was at the crater (XI). 
He made some barometric measurements over the region, and
