at first sight with the angularity of the contours of the moraine. 
It presented the appearance of having been pushed up from 
beneath. At some points there were sharp conical peaks that 
gave the impression of direct elevation from below. This 
appearance was afterwards supported by observations elsewhere 
and there seemed sufficient grounds for believing that the impres- 
sion of the method of its formation was correct. It was found 
that the layers of the ice curved rapidly upward on encountering 
the wind-drift border and the moraine lodged against it, and that 
the morainic débris that resulted from its melting was borne on 
its upturned edge. Under these conditions any motion of the 
layers of the ice must have pushed upwards the material lodged 
upon their edges. 
The material of the moraine was in general quite angular. 
There were occasional well rounded cobblestones and some well 
worn bowlders, while some other fragments were deangulated or 
rubbed and bruised, in a moderate measure, but notwithstanding 
these instances, the prevailing character was one of marked 
angularity. The material was chiefly light colored sandstone of 
the Karnah variety previously alluded to. Some crystalline 
bowlders were present. It would appear, therefore, either that 
the ice-cap was largely underlaid with Karnah sandstone, or else 
that the débris was chiefly picked up near its border, and of these 
alternatives the latter seemed best supported by the distribution 
of the formations and other considerations. 
This moraine was seen to reach along the edge of the ice for 
some miles. To the east it could be seen pursuing a serpentine 
course along the ice front with a notable snow-drift belt outside. 
To the west it could be followed for a shorter distance beyond 
which its presence could not be detected, the ice-cap appearing 
to come down with a moderate slope to the surface of the pla- 
teau without any frontal moraine. But this tract was only seen 
from a distance and a moraine buried beneath a snow-drift 
border may have been present. 
The ice front showed little evidence of motion. It appeared 
from the constitution of the wind-drift border that it was the
