wore formerly triliutarv to this glacier, but it has l)eeii some 
time since either has supplied any ice to it. Its moraines lie in 
perfectly straight lines from one end of tlu' ice to the other, neces- 
sarily l)eing the remnants of the (jld medials that lay on its sur- 
face during a time of greater extent. No moraines appeared 
traceable to the two glaciers coming in from the sides. There 
are several of these medial moraines lying on tliis glacier, indi- 
cating its formation from a considerable numl)er of small ice 
streams. They present one very peculiar feature, that of disap- 
])earing for a certain interval. On following one of them it would 
suddenly be cut otf sharply. l)e a))scnt for a certain (bstance, and 
then reappear at the surface with equally startling sudden- 
ness. This has taken place once on every moraine. Sometimes 
two or three moraines exhibit this phenomenon at about the same 
l)oint. but more often the points ^)i disappearance and reappearance 
on the various moraines seem independent of one another. Close 
examination revealed the missing portions of the moraines lying 
beneath the surface of the ice. their present position being dis- 
closed l)y means of the narrow crevasses. They were 'sometimes 
covered by a thickness of ice of at least six feet. They keep 
their direction perfectly when lieneath the surface. The effect 
produced is as if a long shalloAV l)lock of ice had been lifted up, 
its load of debris deposited in the depression produced, and then 
the block replaced upon it. Xo explanation of this occiUTcd to 
me, and I present it as a curious fact not observed before so far 
as I know. 
The situation and direetion of the moraines on this glacier in- 
dicate a former tiow of the ice from one end of the valle}' to the 
other. There are. however, certain difflculties in the way of this 
view. The material composing the moraines is here of little as- 
sistance in determining the question. The mountains adjoining 
this valley and the neighboring shores of the bay and inlet are all 
of the same material, and of this the moraines are made up. 
()ccasi(jnal large pieces of coarseh' crystalline white calcite oc- 
cur on the moraines. These are sui)plied from the deposits of 
calcite found in fissures in tlie vicinity. I know of none of 
sufficient size to have furnished these pieces in the mountains ad- 
joining the eastern portion of the valley, and do know of 
several to the west. This denotes a proltal)ility of a former 
easterlv movement of the ulacier in this vallcv. There are nianv
