remarkable notes, the whistling of the elk, but 
with only partial success. The story is told 
that the elk left that part of the country, and 
he was unable to keep up with them. 
That there are several thousand elk in the 
Park and adjoining country is quite certain, 
but from the nature of the case it is a difficult 
matter to estimate them. Their number may 
vary from year to year, depending upon the 
severity of the winter and other causes. Ex- 
ceptionally severe seasons would naturally 
cause an increased death-rate. At all events, 
they exist in numbers sufficient to put at rest 
all fear of extermination if they shall only 
be protected and allowed to wander undis- 
turbed. Several favorable seasons might 
cause them to reach the limit of a winter’s 
food supply, but overcrowding must tend to 
a high death-rate, and the struggle for ex- 
istence would keep their number down. The 
migratory habits of the elk would lead them 
to seek new haunts beyond the protected 
region, offering every year opportunities for 
healthy, manly sport to the ambitious hunter 
during the shooting-season.
