The detennmation. in recent years of the 

 upraised marine plane throughout the Hudson- 

 Champlain and Connecticut valleys afforded a 

 good hase line for more extended exploration.^

During the summer of 1917, with financial aid 

 from the research fund of the American Asso- 

 ciation for the Advancement of Science, the 

 writer has been able to determine with pre- 

 cision, or with close approximation, the amount 

 of Post-Glacial land uplift over ISTew England 

 and eastern Canada, as shown by the accom- 

 panying map. 



On the small scale the map is, of course, some- 

 what generalized, but it is confidently believed 

 to fairly represent the truth. The broken
