THE DISTRIBUTION OF SOME CANADIAN PLANTS, AN ARGUMENT 

 FOR THE MARINE ORIGIN OF THE ERIE CLAYS. 



I have long thought that some of the striking anomalies in 

 the distribution of our native plants throw considerable light 

 upon the origin of the Erie clays and their relations to the 

 marine clays and sinds of the Province of Quebec. These Erie 

 clays underlie the Sau^een cliys, but contain no fossils, and we 

 have therefore to look to extraneous sources for information regard- 

 ing their origin. On more than one occasion I have maintained 

 that the sea ^hore plants now so widely scattered a'ound the 

 Great Lakes and elsewhere indicate an extensive inroad of the 

 ocean, and that their original migration to the interior is clearly 

 referable to post pliocene times subsequent to the glacial drift.. 

 The clays and sands succeeding the Erie clays are lacustrine, and 

 the underlying glacial drift, whatever its origin may be, points 

 to a period oi cold too excessive for temperate vegetation. It is 

 difl&cult, then, to resist the conclusion that the migration of"
