sible that what is now the continent of Asia 

 and that of North America were joined. In 

 fact, they come very close together to-day at 

 Bering Strait. If such were the case this con- 

 tinent could have been inhabited from the old 

 world by ^an overland route. This, however, 

 is mere speculation. There are a number of 

 factors that are taken into account in deter- 

 mining the period of the ice age besides the 

 Niagara Eiver and the Falls. The Falls of St. 

 Anthony at Minneapolis (which like the Ni- 

 agara is a creature of the ice age), the wear of 

 water on the shores of the great lakes, the 

 newness of the rocks that are piled up on the 

 terminal moraines, all point to a much shorter 

 period since the ice age than it used to be sup- 

 posed, and indicate that the time does not ex- 

 ceed 10,000 years. 



To the ordinary mind the ice age no doubt 

 seems like a myth, but to the man of science 

 who has made a study of all of these evidences 

 it is as real as any fact in history, and much 

 more real than some of the history we read. 

 In the former case we are dealing with evi- 

 dences that appeal to our senses, while in the 

 latter we are dealing with the recollections of 

 men concerning what purport to have been 

 actual transactions, and we know enough about 

 the human mind to make it difficult sometimes 

 to draw the line between the actual and the 

 imaginary.
