stream of earth was sent flying behind him. Oc- 

 casionally, too, a huge stone was sent hurtling 

 back. This activity roused the curiosity of the 

 sheep, and they approached within perhaps ten or 

 twelve feet. They were lined up and eagerly watch- 

 ing the grizzly when he became aware of their 

 presence. Disliking their close approach, he leaped 

 at them with a terrific "Woof!" The sheep scat- 

 tered wildly but ran only a few yards. Again unit- 

 ing, they fed quietly away, and the grizzly re- 

 turned to his digging. 



In only exceptional cases has the grizzly been a 

 killer of big game. In his search for food he digs out 

 small mammals and kills rabbits and beaver. He 

 is not likely to attempt anything as large as wild 

 sheep, but when a grizzly forms the habit of killing 

 big animals he is likely to make this serve as his 

 entire food-supply. Thus a cattle-killing grizzly is 

 likely to give his chief attention to the killing of 

 cattle, or incidentally to that of sheep, deer, or elk. 

 In the days of the buffalo the great herds fre- 

 quently were trailed by one or more grizzlies. 

 These, however, probably obtained most of their 

 meat from carcasses left behind by storms, drown- 

 ing, or other means of death.
