THE ENEMIES OF WILD LIFE 195 
any campaign against coyotes. Such injurious insects as 
grasshoppers, crickets, June-bugs (white grubs), etc., are 
also eaten by coyotes. Nevertheless it would appear that 
the damage they inflict far outweighs the benefits they ac- 
complish. Peculiarly enough they are also fond of fruit 
and consume wild fruits and berries. 
Cougar.—The cougar or puma, also known as the moun- 
tain lion or panther, is the largest of the cat tribe in North 
America. In Canada it is to be found in the Rocky Moun- 
tains and westward to Vancouver Island, on which it ap- 
pears to be most common. Large specimens may measure 
7 to 8 feet in length, and weigh over 200 pounds. They 
prey upon every kind of game, but are specially destructive 
to mountain sheep, goat, and deer, and a large male cougar 
will kill a horse, cow, moose, or wapiti. Deer form their 
chief prey. When cougars occur in numbers the deer and 
mountain sheep invariably decrease in numbers; for exam- 
ple, I am informed that .the decrease in deer and sheep 
in the Lillooet region of British Columbia, which formerly 
abounded in such game, has been largely due to the depre- 
dations of cougars, which are increasing in that region, al- 
though a steady decrease in cougars in British Columbia as 
a whole is reported. 
THE Wor AND Coyote ProBLemM As AFFECTING 
LivE-Stock INTERESTS 
From an economic point of view the destruction of live 
stock, especially sheep, by wolves, and particularly by 
coyotes, constitutes a more serious problem than the de- 
struction of wild life, and it is fitting that in such a presen- 
tation as J am making of the economic aspect of our native 
predatory animals we should consider the relation of these 
animals to our agricultural interests.

tion that I have made into the losses inflicted by these
