FOUR FAMOUS AMERICAN FUR-BEARERS 
Marten 
Mink 
These four animals, with the American beaver, constituted the foundation on which the fur industry of America rested 
for more than a century. Unfortunately, however, there does not seem to be the slightest possibility of multiplying any 
one of them by any known process of fur farming. They must breed, live and thrive in an absolutely wild state or perish, 
and it is now for the fur trade to determine whether it is possible to throw around them sufficient safeguards to permit 
them to exist on a continuing basis. 
From the ‘“‘American Natural History’, by permission of Charles Scribner's Sons. 
bitive laws thoroughly enforced, are all that 
is necessary in the writer’s opinion to conserve 
fur-bearing animals for any definite time. 
There are periods, such as the last three or 
four years, in which a great incentive is given 
to trapping by the high prices which are of- 
fered, but on the other hand, there are periods 
of depression, such as are taking place at the 
present time, going a great deal towards con- 
servation, by lessening the incentive to trap. 
Yours sincerely,
