When silver fox skins are vi'orth from $300 to $600 a skin it does not need a Colonel Sellers to see ijolden possibilities in the business. The raising of mink and beaver, and perhaps otter, for their fur is also thought to be entirely feasible. The beaver is being protected in Canada and in some of our own states. It should be protected in all, for apparently pro- tection is all that is required to enable the animal to reestablish itself in many of its old haunts. After being safeguarded for a term of years, judicious trapping might then be allowed, and thus this remarkable and valuable fur-bearer be preserved in- definitely, to be a source of both interest and profit to future generations. Even the despised skunk, which is easily cared for and is wonderfully prolific, can, it is believed, be raised in confinement with profit. The idea of raising furs for the market is by no means new. Many attempts have been made to breed foxes for profit, especially in certain islands of .Alaska, where the conditions would seem tu be ideal. Some of the ventures appear to have proved remunerative, but many fail- ures have resulted, chiefly as the result of inexperience and lack of knowledge, especially of the proper feeding and care of the animals. It is thought that the dif- ficulties are by no means insuperable and that they can be overcome by study and carefully conducted experiments. Thus the ends sought by the Biological Survey in its investigations of mammals differ considerably from those aimed at in its study of birds. The more carefully birds' habits are studied and their food investigated, the more apparent is it that man cannot do without them. Such is b>- no means true
