slaughter that is taking place, one must allow for animals which were

A glance at some of the noteworthy species sought by the fur 
trade will show something of the scope and demands of this industry. 
Altogether, the fur trade utilizes, at the very least, some one hundred 
twenty-five species, the exact number being difficult to determine 
because of the employment of trade names, which mean nothing to 
the zoologist. We have included in the table with this paper only the 
more important species.
