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

 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
