448 R. S. TARR — GLACIATION OF MOtJNT KTAADN, MAINE 



The proposition is made, as an hypothesis, following the suggestion 

 of Hitchcock, that between the time of general glaciation and local val- 

 ley glaciers, there was a stage during which from the various highland 

 centers of New England glaciers reached northward into the Saint Law- 

 rence valley. This would account for the features described by the 

 Canadian geologists and harmonize the conflicting views of the Cana- 

 dian and American glacialists.
