Glaciation and Superficial Deposits. 



The hills everywhere inland to the east of Hudson Bay have been ice grooving 

 rounded off, planed and scratched by an immense glacier, which moved 

 over the highest land, where the stripe and ice-grooves upon the rock 

 surface attest it former presence. 



The following list of striae show that the glacier moved in a uniform 

 direction, a few degrees south of west, over all inequalities of the sur- 

 face, except the deep valley of Great Whale River, where it was 

 diverted and followed the course of the river valley. 



On the Clearwater route the general direction is more nearly west 

 than in the country to the south. 



Everywhere the glacier appears to have followed the general slope 



of the country from the high interior gathering grounds. 



From the evidence afforded by stria? and travelled boulderson the rivers Flow of great 



glacier* 



falling into Hudson Bay from the west and south, collected by Dr. R. 

 Bell it would appear that the continental glacier flowed down from the 

 high land on the east side of the bay, crossed it, and had momentum and 

 thickness sufficient to push itself in a direction south of west, up the 

 west side over the wide margin of flat deposits of limestone, which 

 extend inland from the present coast line some 200 miles, and then 

 over the higher Archaean country that forms the watershed between 

 Hudson Bay and the great lakes.
