America, from the logic of the conditions of to-day. Thanks 
to the splendid mass of information that has been accumulated 
regarding this group, we are able to draw certain conclusions. 
I think that the caribou of the Canadian Barren Grounds and 
northeastern Alaska will survive in great numbers for at 
DEER DESTRUCTION IN MONTANA, 1913. 
The most deadly of all hunters is the one who kills females and young! This is extermination! 
least another century; that the caribou herds of Newfound- 
land will last nearly as long, and that in fifty years or less all 
the caribou of the great northwestern wilderness will be swept 
away. 
The reasons for these conclusions are by no means obscure, 
or far-fetched. 
In the first place, the Barren Ground caribou are to-day 
enormously numerous—undoubtedly running up’ into mil- 
lions. It cannot be possible that they are being killed faster
