Introduction. 



It is generally admitted by geologists that a differential rising of the 

 land toward the northeast has taken place in Pleistocene times over a 

 great breadth of North America, extending from the Canadian northwest 

 territories to the New England states. The unequal elevation of the 

 land has been demonstrated by Tyrrell in Manitoba, Canada, and, among 

 others, by Chamberlin, McGee, and Leverett in the western United States, 

 by Lawson around lake Superior, by Spencer and Taylor in Ontario,
