bulk of the Ameiicans. They were here for untold ages, 

 aud these trifling accessions were of little occouut. 



If the human race is all from one pair, as I suppose, it 

 was split up hundreds of thousands of years ago into the 

 four main strains. One can only say that the America-n and 

 INIongolian were together some time aft-er sepai-ajting from 

 tiie other parent stocks, The^' separat'cd later and a branch 

 occupied Asia. Another branch, a remarkably homogeneous 

 one, 0€cupied America, but this was sc' long ago that though 

 the physical likeness remains tO' some extent, no language 

 trace can now be found. 



Sinc-o delivering this lecture the Yale exploring expedi- 

 tion in Peru has found human bones in glacial drift which 

 is calculated t-o have been deposited at least more than 

 150,090 years ago. 



Thousands, or hundreds of thousoj:ids of years ago, the 

 different branches of the liumaJi race separat-ed from each 

 other and left their ancient home, which was perhaps on 

 that sliodowy continent now buried beneath the waters of 

 the Indian Ocean. There &oem to have been three grand 

 divisions — Caucsjsian, INIongolian and Ethiopian, which 

 lat«r divided into minor races ajid which took different 

 routes, as I have just explained, in their outward march 

 to people the earth. In these hundreds of thou&ands of 

 yeai^B of wandering, mider different conditions and different 

 climates in all parts of the earth, the various branches of 

 our race collected experience and wisdom and adaptability, 

 each to its own circumstances. Each race has Bomcthing 

 of its own that it can teach all the rest, some talent or 

 expeneiice in w^hich it exc-els all othcre, and so e^xry race 

 can learn from all of the others. 



Finally, after these great Maaiderings, they are at 

 length combing together again in the new continent where 

 the East meets the West, each with its talents to add to 

 the comnaon stock. 



In the two Americas, North and South, we have rep- 

 resentatives of almost all the different races of the globe,
