T/te Life of Yesterday 



of the ox tribe. This animal did not greatly 

 exceed the Western bison in bulk ; it seems to 

 have been less than a foot higher at the shoul- 

 ders, but its great horns had a sweep of from 

 6 to 8 feet from tip to tip.* This magnificent 

 animal was found from Ohio southward into 

 Florida on the one hand, and Texas on the 

 other ; but it appears not to have been a com- 

 mon animal. 



The period of warmth during which the 

 sloths and their associates came north appears 

 to have been succeeded by a glacial period, and 

 this in turn was followed by a climate much 

 the same as it is at present. This was the time 

 of the final appearance of the Mastodon, when 

 it was a common animal in New York and New 

 Jersey. One other animal should be mentioned 

 here, if only to emphasize the uncertainties of 

 preservation, and that is a member of the deer 



* The pair of horn-cores in the collection of the Cincinnati 

 Society of Natural History measure 6 feet 6 inches along the 

 curve from tip to tip, and the horns themselves that fitted over 

 these bony cores would be quite a little longer. A pair of horn- 

 cores, attached to the frontal bone, have just been found in Kan- 

 sas which measure 7 feet between the tips and 8 feet 6 inches 

 along the curve.
