and ice only, and formed a gathering ground which sent 
out local glaciers in all directions, as seems more probable, 
is a question to be decided by future investigations. The 
southern or southwestern portions are intensely glaciated, 
especially in the Lake Superior and Lake of the Woods 
regions.. There seems no doubt that the glaciers there 
were large and probably became confluent. 
GENERAL CoNCLUSIONS. 
Summing up the data thus far obtained, I conclude that 
the glaciation of Kastern Canada has been effected by local 
glaciers on the higher grounds, and drift-ice or ice-bergs on 
the lower coastal areas. In their movements, the glaciers, 
generally speaking, followed the slopes of the land, or the 
drainage channels. They seem to have had extensive 
gathering grounds upon the more elevated parts of the 
country where snow-fields and nevé-ice existed. Whenever 
motion began, these became converted into glacier-ice. Upon 
those areas where the snow never underwent change into 
ice no striation of the rocks is found. Some of the glaciers 
appear to have been quite large, and those from adjacent 
drainage areas may have coalesced on the lower grounds 
and become confluent. At all events, the slopes and coastal 
tracts are, generally speaking, more glaciated than the in- 
terior and higher grounds. ach area or centre of disper- 
sion has, however, had its own glacier or glaciers. In Nova 
- Scotia there was a shedding of the ice from the Cobequid 
Mountains northward and southward; and probably the 
elevation known as the South Mountain likewise sent gla- 
ciers down its slopes on either side. In New Brunswick, 
the low water-shed running across it from north-west to 
south-east, sent off glaciers in opposite directions, or north- 
eastwardly on the northern slope and south-eastwardly on 
the southern, these courses being deviated from in a greater 
or less degree, however, according as the ice was influenced 
by local topographic features. The Shickshock or Notre
