Man in America. — The American Indians are so plainly Mongoloids 

 that they must have come from Asia; and the means of travel available 

 to these people almost guarantees that they crossed the Bering Strait, 

 which could have been dry. The Asiatics most like the American 

 Indians are not the Chinese, but the more generalized people of central 

 Asia, Tibet, or the East Indies. Migrations of these people extended to 

 Patagonia on the south, and to the Atlantic seaboard, long before white 

 men came to America. The Eskimos of the arctic region are more nearly 

 like the Chinese and Siberians, and probably are the latest immigrants. 



Important discoveries of arrow points with fossil bison in New 

 Mexico in 1927 were followed in rapid succession by other revelations 

 of culture in relation to such extinct animals as horses, camels, masto- 

 dons, and ground sloths. The making of pottery, an art which for some 

 reason Cro-Magnon man never developed, has entered extensively into 

 the later history of culture in America. The New Mexico points were 

 interpi-eted as belonging to the late Ice Age, or perhaps 25,000 years 

 ago, so the migration must have occurred earlier.
