free-falling little cataracts. Along the sides of the glacier these 
are gathered into a considerable lateral stream which occupies 
the trench between the glacier and the side of the valley. At the 
end of the glacier small streamlets flow away in large numbers 
but there is no central stream, nor any large central tunnel after 
the fashion of Alpine glaciers. The lateral streams are usually 
murky, but the frontal streams are essentially clear. 
The plain in front of the glacier is produced by its own drain- 
age and consists of bowlders, cobbles and coarse gravel, with 
some sand and silt. It spreads from bluff to bluff in a nearly 
uniform plane. There is no terminal moraine immediately in 
front of the glacier, unless the talus at its base be so regarded. 
Between its extremity and the sea, along the sides of the valley, 
there are some accumulations of erratic material that perhaps 
represent old moraines, but they scarcely have a distinctive 
character. 
Ascent to the ice-cap—On two occasions we ascended the 
plateau immediately east of Bryant glacier and went back to the 
edge of the ice-cap of the peninsula. At first the surface was 
found to be formed wholly of frost-riven fragments of the sand- 
stone and shale series that constitute the uppermost member 
of the clastic terrane before described. Here and there an erratic 
bowlder was seen, but the amount of detectable drift on the surface 
was very small. Ata height of about 1600 feet and at a point 
perhaps two miles back from the Gulf, moraine-like aggregations 
of rounded erratics were met. These did not form a sharply 
defined moraine with a definite outer border, but the transition 
from local débris was measurably abrupt. As the ascent was 
continued there was an increase in the amount of drift and the 
topography became more moraine-like, although it never passed 
beyond the milder type of morainic hills and hollows. The 
material was chiefly bowlders ranging from one to three or four 
feet in diameter. Cobbles and coarse gravel were present, but 
sandy and clayey constituents were scant. As the edge of the 
ice-Cap was approached streamlets issuing from the border of the 
ice were encountered and became increasingly frequent. They
