90 THE BIOLOGY OF HARDING COUNTY 



Prairie Jumping-mouse (Zapus hudsonius campestris). Kan- 

 garoo mice or "rats" have been taken by Mr. Over in Perkins 

 County. 



Porcupine (Erethizon epiranthum epi.vanthum) . We ran on 

 to several porcupines and signs of their work as barkers of young 

 pine trees were plentiful in the forest reserves. 



Jack-rabbit or Prairie Hare (Lepus campestris). Fairly com- 

 mon in this area. 



Western Cottontail (Lepus nuttalli). Quite plentiful in the 

 groves. 



[Canada Lynx (Lyn.v canadcnsis cental ensis). George Craig 

 and others claim that specimens of this lynx have been taken 

 recently in the Cave Hills.] 



Bobcat (Lyn.v nifus). Plentiful in the badlands and enter- 

 ing the buttes where our party saw one in 1910. 



Kit Fox or Swift (I'nlpes I'do.v I'do.r). While the- Swift is 

 so rare here that a rancher has hunted with hounds for years 

 without ever seeing one, it nevertheless undoubtedly occurs. We 

 saw one along the Little Missouri Valley in North Dakota. Catron 

 reports having trapped a few. 



Prairie Red Fo>x (I'nlpes regalis). Catron reports having 

 trapped two or three red foxes in this county. Another reports 

 them not rare about the Long Pines. 



Gray or Buffalo Wolf (Canis occid entails occidentalism . Quite 

 plentiful. As an indication of its abundance I may quote figures 

 given me in 1910 by Assistant Forest Supervisor Haines : A gov- 

 ernment trapper caught 5 adult and 25 pups in two months about 

 the Short Pines and 2 adults and u pups about the Cave Hills in 

 two months. 



Coyote (Cams latrans nebracensis] . Generally considered as 

 abundant. However, in 1912, I traveled very widely throughout 

 this area and saw but one though in 1910 and 1911 I saw several. 

 Haines gave me the following data concerning the number taken 

 by government trapper in the Short Pines in two months : 34, 

 in the Cave Hills, 2 months, 22. These were the same periods 

 during which the gray wolves were trapped and scarcely indicate 

 the relative abundance of the two because of the greater bounty on 

 the Gray. The same trapper took 102 coyotes and but 4 wolves 

 in a whole winter (1909-10) in the Ekalaha Forest.
