Maui to complete the survey which is the basis of the present 
report. 
The Museum is under special obligation to members of the- 
Von Tempsky family, who have thoroughly explored the crater on 
their many hunting and camping trips. Their guidance and assist- 
ance are largely responsible for the results obtained. Acknowledg- 
ment is also made to Mr. H. A. Baldwin, who generously supplied 
horses and pack mules, and to Mr. W. A. Clark, manager of Grove 
Ranch, who assisted in many ways. ‘Thanks are due also to Mr. 
Aitken for the use of parts of his preliminary report which at 
various points supplement the observations of the writer.

PUU NAUE GROUP 
Exactly in the center of the Crater a symmetrical gray cin- 
der cone, Puu Naue, rises to a height of 250 feet above the level 
floor. Its crater dotted inside and out with the beautiful silver- 
sword plant and stunted pilo bushes, is 198 feet in depth and 750 
feet in diameter. At the bottom are three terraced platforms (PI. 
XX, 4). The one on the north slope is in ruins as a large boul- 
der, rolling down from above, has destroyed a good part of the back 
and front retaining walls. Its horizontal dimensions? are 26 feet on 
the north, 24 feet on the sou’h, 11% feet on the eas*, and 10% feet 
on the west. The back wall rests on the slope of the cinders. The 
height of the front wall, though 34 inches at the southeast corner, 
averages not more than 32 inches. The east wall is not only higher 
and more solidly built than the others but is twice as wide and 
presents a table-like top. The structure has the appearance of a 
stone inclosure, but the whole platform was probably once filled 
with sand and gravel, so that its surface was level with the lower 
part of the surrounding wall, as were the other two platforms, 
which are in a good state of preservation. 
Although this structure is in ruins there is nothing to indi- 
cate that it is older than the east and south platforms. Possibly 
the reason for building it farther up on the slopes was that the 
* Measurements are estimated to the nearest half foot; to be more pre- 
cise would give a wrong impression, as the construction of the walls was 
always rough and irregular.
