The arctic fox is a good deal smaller than the common fox, and has ears so short and rounded that they look just as if they had been cropped.
In order to allow it to travel over the slippery ice, the arctic fox has the soles of its feet covered with long stiff hairs, which give it a perfectly firm foothold on the frozen surface.
The arctic fox is not nearly such a clever animal as the common fox, and is very easily trapped. If a hunter follows one, it will certainly run into its hole; but a moment or two later it is almost sure to poke out its head in order to yelp at him, so that he is easily able to shoot it. The consequence is that these animals are destroyed in very great numbers for the sake of their skins, those with bluish fur being especially valuable.
First-class skins of these foxes are, in truth, among the most costly of furs. In view of this, men interested in the fur-trade in Alaska have endeavored to raise them in captivity, so as to obtain a constant supply of their pelts. This experiment has succeeded best on a certain island in Bering Sea, where a large colony of arctic foxes is kept, guarded and tended by Eskimos, who feed them, and who once a year catch and kill a certain number when their fur is in its best condition.
Besides the arctic fox, which of course is found in American as well as other arctic regions, this country has many species of fox that belong peculiarly to itself. William T. Hornaday, director of the New York Zoölogical Park, who has written many instructive things about animals, tells us in his "American Natural History" that north of Mexico this continent has sixteen distinct species of foxes, some of which have several subspecies.
The American fox most widely found is that which Mr. Hornaday calls "our wise old friend, the red fox," which is so well known in many parts of the country. It is a very cunning creature, "so well able to take care of itself that it refuses to be exterminated." Still we are told that it was not hard for the early settlers in this country to outwit the red foxes, and to shoot them and trap them when they came into the clearings where the settlers made their homes. It is easier to get the better of these animals in a wild region than where many people live, for the foxes are sharp observers and appear to learn many things from seeing what their human neighbors do. Naturalists tell us that in this way the American foxes have come to be almost as intelligent as those of the Old World. The red fox, we are told, "now holds his own against man, as much by boldness and audacity as by caution; few of our wild animals look on man with so little awe."
