The Mammoth, Elephas primigenius, the 

 first elephant of all,* ranged from Alaska south- 

 easterly to about the latitude of the Middle 

 States. This corresponds roughly to a belt of 

 territory running along the edge of the great 

 ice sheet where the mammoth probably found 

 the right conditions of temperature, vegetation, 

 and fairly open country. 



The Mastodon (Mastodon americanus) was a 

 more southern animal, and while in the north- 

 ern portion of its range it seems to have been 

 clad in a coat of hair and capable of enduring 

 considerable cold, yet the true habitat of the 

 Mastodon was south of that of the Mammoth, 

 in the forest country where water was plentiful. 



We are as yet unable to trace the history 

 of the Mastodon back to its place of origin. It 

 may have developed from some earlier species 

 residing in this country, but this is hardly 



* As a matter of fact this name is now a misnomer, since earlier 

 elephants are known, but a scientific name once bestowed on an 

 animal must stay.
