River (Manitoba), and Moose and Missinaibi Rivers. The 

 thirteen localities are so situated as to bear a more or less definite relation 

 to one another, and all lie within the limits of the Pleistocene Sea which 

 extended up the valley of the St. Lawrence, and occupied the area of the 

 present Great Lakes. It should be kept in mind in this connection, how- 

 ever, that saltwater forms are to be met with only as far west as Green's 

 Oreek, near Ottawa, while freshwater types prevail in all the more 

 western localities, which thus correspond in a general way with the de- 

 posits of Ohio, Indiana, Illinois, Minnesota, Manitoba, and other western 



Distributio7i of Pleistocene Plants.
