52 WILD NEIGHBORS CHAP. 



uncommon, and gives an account of one measur- 

 ing sixty feet, where the cat leaped from a ledge 

 twenty feet high and pushed the deer he struck a

 on top of a rock that could be reached only by a 

 vertical jump of twenty feet. 



Their ordinary gait is a slouching walk or trot, 

 and they are not swift of foot, except for a short

The "blood-curdling screams" of the puma have

 but evidence of this screaming, which will bear

 heard in the Rocky Mountains at night, shrill 

 screams, so piercing and cat-like, yet of so much 

 force and loudness, that it did not seem likely any- 

 thing less than a cougar could utter them. I be- 

 lieved then, and am still of the opinion, that these 

 were the cries of a puma : but I did not see the 

 animal. Indeed, evidence so positive as this will 

 be difficult to obtain, since loud yells are heard 

 mainly at night, and would be unlikely to be 

 emitted in the presence of a listener at any time. 

 Says Mr. W. A. Perry, who has had a long per-

 Big Game of North America " has written an ex- 

 cellent account of their habits in the Northwest :
