398 Reminiscences of 



and Wyoming have resulted in the generalizing of

 day from its five-toed ancestral type of inferior 

 size. 



Curiously interesting is the history of evolution, 

 yet but partially explained, but sufficiently to in- 

 dicate a great future advance, though probably never 

 to be fully illustrated.

 formerly a numerous and powerful one, is in late 

 years reduced to a few thousand. Comparatively

 texture, and often sell as high as $ 100 or more. They are
