the periphery. On the east side the ice rested against 
three low hills, beyond which were lakes supplied in part 
from its melting. In one place a lobe of ice touched one 
of the lakes. In a hollow on the side of one of the hills 
a lakelet was imprisoned by the ice, one of its shores 
being constituted wholly by the glacier. On the west is 
an embayment among high mountains, into which the ice 
sent a tongue two miles long, but there was no lake and 
no visible outlet for the water, which must have found 
its way to the sea beneath the body of the glacier. This 
feature is specially remarkable from the fact that the sub- 
glacial water could not follow the course of the ice, but for

several miles must either move in the opposite direction 
or take some independent route. 
Columbia Bay, to which the glacier flows, is from four 
to five miles broad and is locally divided by a group of 
islands. The western arm, two and a half miles broad, is 
comparatively simple in outline and is probably deep. It 
received the principal discharge from the glacier, which 
spanned it from side to side with a cliff about 300 feet 
high. The eastern arm, irregular in outline and judged 
from the configuration of its shores to be comparatively 
shallow, was bordered by the glacier for a mile and 
a quarter, but the ice cliff was less lofty, and a compari¬ 
son of its outline with other portions of the glacier showed
