GLACIATION OF HASTERN CANADA. 
By Ropprr CHALMERs, 
Of the Geological Survey of Canada. 
The investigations hitherto made in regard to the 
glaciation of Eastern Canada show that, instead of its 
having been caused by a continental ice-sheet moving over 
the region from north to south, as has been supposed, local 
glaciers upon the higher grounds, and icebergs or floating 
ice striating the lower coastal and estuarine tracts, during 
a period of submergence, were agents sufficiently powerful 
to produce all the phenomena observed. The latter 
theory, with some modifications, is the one so long main- 
tained by Sir William Dawson, who has studied the 
glaciation of this country for forty years or more.’ A 
number of other observers have, of late years, been at 
work, however, and Sir William’s views are now, it would 
seem, about to receive abundant confirmation, The large
