CHAPTEE I. 



HISTORICAL NOTICES. 



Canada presents unsurpassed facilities for the study of 

 the pleistocene deposits. Extending across the American 

 Continent from the Atlantic to the Pacific, in the widest 

 part of that continent, and reaching from the latitude of 

 45° to the polar regions, possessing great plains covered 

 with drift material, and mountainous districts heavily 

 marked with the action of land ice, and having in many 

 places abundance of fossil remains in its more recent 

 deposits, it has the same relative facilities for the study 

 of this later geological period that it has for the earlier 

 Laurentian ; and it has been one of the objects of the 

 ambition of the writer for the last thirty years, to do a 

 little toward making it a typical region for the Pleisto- 

 cene, as Logan has for the Laurentian. I shall endeavour, 

 therefore, to sketch the Pleistocene as it appears in 

 Canada. 



In making this attempt, I have all along felt compelled
