GLACIAL STUDIES IN GREENLAND. 839 
(Fig. 57) was taken, which seems to bear upon the interpreta- 
tion of the projection of the layers of the ice over each other 
alluded to in the descriptions of the two preceding glaciers. 
Attention was there called to the hypothesis that this projection 
was due to the superior melting of the débris-bearing layer. It 
seemed that there was no doubt as to the correctness of this 
interpretation in many cases, perhaps in most cases, but there 
appeared to be other cases in which the explanation was less 
satisfactory, if not untenable. In the photograph here taken, 
reproduced in Fig. 57, it will be seen that the under edge of 
several of the layers is notably cleaner and fresher than the outer 
edges which are roughened and débris-covered. The aspect is 
strikingly like that of layers which have moved over each other 
in such a way as to expose fresh under-edges. Unfortunately 
this particular feature did not attract my attention when on the 
ground, and I am only able to submit the evidence of the photo- 
graph for what it is worth. The strong individuality of the beds 
is at least worthy of note. 
A short distance beyond the point where the ice is seen to 
be creeping over its moraine (Fig. 55), the border again retires 
within the moraine, and this continues perhaps half a mile in 
the course of which the moraine deploys into a fine series of 
conjoined morainic ridges, closely pressed together, but yet pre- 
senting distinct and sharp crests. ‘These reach a height, accor- 
ding to a single aneroid measurement, of about 275 feet abcve 
the Cove and attain a breadth and massiveness which entitles 
them to rank among notable moraines. Here, however, as before, 
it was observed that ice was buried beneath the débris, and it 
was impossible to determine how far the massiveness of the 
moraine was rendered illusive by the includedice. There seemed 
ground, however, to believe that the melting of the concealed 
ice will cause a notable shrinkage of the moraine, and in 
doing this will greatly increase the irregularity of its surface. 
It will then doubtless become a typical “humpty-dumpty ” 
moraine. 
Following this stout moraine southward, the glacier is found 
again to be creeping out uponit. But here the ice not only
