44 Deer and Antelope of North America 



this season were preying upon them practically 

 to the exclusion of everything else. We came 

 upon one large fawn which had been killed by a 

 bobcat. The gray wolves were also preying upon 

 them. A party of these wolves can sometimes 

 run down even an unwounded blacktail ; I have 

 myself known of their performing this feat. Twice

 intermediate between those of the species that
