The black, cross and silver foxes are commonly supposed to be only color varieties of the red, there being no difference whatever, except in the fur. While naturalists all agree on this subject there is considerable difference of opinion among others who give as proof that they are of a different species, the fact that the black, cross and silver are only found in the northern districts while the red variety is found well down into the south. There are, however, certain facts which go to prove that they are all of the same variety or if different that they interbreed, the most convincing of these being the fact that the various colors are sometimes found in the same litter. But, be this as it may, the matter is of little importance to the prospective fox breeder as it has become a well known fact that the red color can be entirely eliminated by careful breeding.
The red fox is found throughout the greater part of Canada and the United States except in the far south where it is replaced by the gray species and in the extreme northern portions of Canada and Alaska, where it gives place to the Arctic fox, also they are not found in the far western states nor on the Pacific coast, being replaced here by the gray. They are perhaps most abundant in the New England States, Newfoundland and the eastern provinces of Canada, but are also found in good numbers in parts of New York, Pennsylvania, Virginia, West Virginia and the mountainous and hilly sections of the South.
The silver and black foxes are found but rarely in the most northern tier of states and are probably found in the greatest numbers in Newfoundland, Labrador, northern Quebec and northern Ontario, but an odd specimen is occasionally met with in all parts of Canada. They appear also to be quite plentiful in the interior of Alaska and the Yukon Province of Canada. The range of the cross fox is the same as that of the silver and black except that it probably extends somewhat farther southward into the United States.
Of the gray foxes, several varieties are recognized, all however, being very much alike. They are found throughout the Southern and South Central States—in the east being found as far north as Connecticut and on the Pacific Coast are found in California and Oregon.
The Arctic fox, also known as the blue fox and the white fox, is found only in northern Canada and Alaska. In the most northern parts of their range they are a bluish color in summer, changing to white in winter, but in the lower latitudes they retain the blue color throughout the year.
There is an immense difference in the value of the various varieties of foxes. While the fur of the gray variety is seldom worth more than a dollar or a dollar and a half, that of the fine silver and black foxes will range from several hundred to a thousand dollars, and more if the skin is an exceptionally fine one. The Arctic fox comes next in value to the silver, while the cross is as a rule of less value, depending mostly on color, and the red variety sells for from three to five dollars each and upwards for prime skins.

The various members of the red fox family are practically the same as regards habits, being influenced to a certain extent by environments, differences in climate and food, etc., but on the whole very much alike. They are all of a cunning, wary and suspicious nature and it is owing to this fact alone that they have been enabled to live and thrive in the face of the persistent hunting and trapping. They are hardy animals and while they generally have a den somewhere on the side of a gravelly or sandy hill, they spend comparatively little of their time in the dens and prefer to spend the day in a bunch of grass or weeds, a clump of brush, or, curled up on top of a stump.
