moraine, beyond which rose the great dome of the ice-cap. 
Strangely enough here was a terminal moraine that was not ter- 
minal; a terminal moraine with an icy tract outside. This outer 
tract was in part fresh snow almost perfectly white, indicating 
that it was a wind-drift accumulation of recent date. At points, 
however, older discolored snow or ice appeared beneath it and 
in a few places stratified granular ice of glacial aspect and con-

ward from a point a short distance east of the Bryant glacier. The débris-strewn 
portion of the plateau forms the immediate foreground. Beyond this is the wind-drift 
belt of snow lodged outside the terminal moraine which lies just beyond it in the mid- 
dle foreground. ‘The dark lines of débris in the center of the picture are also parts of 
the terminal moraine which pursues a serpentine course controlled by the topography. 
The white portion in the center and at the left and the dome in the background are 
parts of the ice-cap. 
taining some rocky material was seen. It was not clear, how- 
ever, that this was not material that had rolled down the steep 
slope from the moraine above. The phenomenon was at first 
exceedingly puzzling, but subsequent study and the light which 
Lieutenant Peary threw upon the subject rendered the elucidation 
altogether clear. Lieutenant Peary (who had not yet been met ) 
subsequently informed me that the winds of the ice-cap usually 
flow down its slope much as though they were independent and 
simply controlled by gravity. It is easy to see that the air in con- 
tact with the surface of the ice-cap becomes exceptionally cold.
