that the receipts from these sales will aggregate 8 to 10 per 
cent of the cost of operations, and the net proceeds are 
turned into the United States Treasury. 
In the annual report of the Biological Survey for the year 
ending June 30, 1919, it is stated that a force of from 400 
to 500 hunters is employed in the destruction of predatory 
animals, under the direction of district inspectors in the 
nine districts mentioned above. About one-fifth of these 
are paid from co-operative funds provided by the States 
or contributed by local organizations or individuals. The 
net proceeds already received for the skins taken during 
the year amount to $76,128.56. 
The work of the United States Department of Agriculture 
demonstrates very conclusively the success of the policy of 
properly organized and systematic hunting by paid hunters, 
working under the close direction of district inspectors, as 
a means of destroying predatory animals over a large area, 
and it affords an excellent object-lesson of what might be 
done in Canada by the adoption of a similar policy.

Lynzx.—The Canada lynx is found throughout the Do- 
minion from Nova Scotia to British Columbia, and north- 
_ ward as far as the limits of our northern forests. Richardson 
states that it is found on the Mackenzie River as far north 
as latitude 66°. It is too well known to need description, 
but, as it is sometimes confused with the bobcat or bay 
lynx of eastern North America by the uninitiated, it may 
be pointed out that the Canada lynx is distinguished from 
the latter animal by its lighter gray colour, the tuft of long 
black hairs on the tips of its ears, and the large, hairy paws. 
Its chief food is the varying hare or rabbit, and the close 
relation between the periodic fluctuations of the rabbit and 
those of the lynx is discussed in another chapter. It also
