side the glacier ends upon these soft deposits, diminishing in 
thickness to an edge. These side portions of the glacier, espec- 
ially the eastern side, are as notably smooth as the central portion 
is lirokeu. Near the front of the glacier three low mountains 
protrude from the ice which entirely surrounds them. On these 
were Dr. Reid's stations G, H and 1. The western one, G, is 
much the largest and highest, and forms a conspicuous feature in 
the landscape seen in looking toward the ice from the l)ay. 
TRIBUTARIES OF MITIR GLACIER. 
The greater portion of the ice which reaches the front of Muir 
glacier at the present day is supplied ])y the two great ice-streams 
which enter the basin from the northwest.* Muir glacier proper 
and the northwestern liranch. The former is the larger, has a 
length of certainly thirty-five miles and probabl}- more, and is 
deeply and abundantly crevassed for a great distance back from 
the ice front. The central and larger portion of the ice front 
derives its ice from this source. The northwestern branch is only 
second in size to this one. Its length is not so great nor its crevasses 
so numerous and profound. Its ice reaches Muir inlet to the west 
of the ice from Muir glacier proper, The next most considerable 
tributaries are the two northern branches. These have great 
length but will not compare in size with the last two. They fur- 
nish the ice which l)reaks awa}* into the water at the eastern cor- 
ner of the inlet. The Western Ijranch is quite completely sepa- 
rated from the rest of the glaciers by the numerous low mountains 
that protrude from the ice. Its interesting featui-es are its nu- 
merous connections with its Northwestern branch through the 
mountain gaps, and its source on a saddle from which ice flows in 
both directions, a feature shared by other glaciers in the basin. 
The ice from this branch does not enter the water, but dies out on 
the gravel deposit which forms the western shore of Muir inlet. 
Eustenihranches. — That portion of the amphitheatre of Muir 
glacier lying east of a line drawn from Snow dome to the eastern 
corner of the inlet is occupied by a mass of ice nearly inert, and 
slowly rotting where it lies. Stakes placed across it about half a 
mile back from the front, at the end of three weeks showed either 
no motion at all. or else an extremely slight one. The surface of 
all this portion of the glacier is extremely smooth. Crevasses
