As for the size of the mastodon, this, hke 

 that of the mammoth, is popularly much over- 

 estimated, and it is more than doubtful if any 

 attained the height of a full-grown African 

 elephant. The largest femur, or thigh-bone, 

 that has come under the writer's notice was 

 one he measured as it lay in the earth at 

 Kimmswick, and this was just four feet long, 

 three inches shorter than the thigh-bone of 

 Jumbo. Several of the largest thigh-bones
