As before stated one should use care in selecting animals for breeding purposes as it is in this way that the quality of the fur will be improved and the business made to be a profitable one. All small and weak animals and those showing considerable white fur, especially males should be killed off while the fur is in good condition. If you wish to increase the number of animals do not be tempted for the sake of the higher prices realized for the finer skins to kill off animals that should be kept for breeding. The animals should never be allowed to become frightened by the intrusion of dogs into the enclosure--dogs should be kept away at all times. The skunk raiser must watch closely at all times to see that the enclosure fences are in good shape so that the animals do not escape. If they are found digging holes near the fence, these holes should be filled up so as to discourage the workers. Fleas and other parasites are likely to bother the animals and they should have plenty of room so that they can change dens when the old habitations become infested with vermin. On the whole, one should study the habits of the animals on every opportunity and attend to their wants. If one will give the proper attention to the animals and take an interest in them there is no reason why he should not succeed. CHAPTER VII. MINK RAISING. There is only one species of mink found in North America, altho there are a number of varieties differing in size, color and quality of fur. Thus we find in Northern Maine and New Brunswick a very small variety having a fine silky fur of a very dark shade; farther west and south a somewhat larger variety, paler in color, and thruout the Mississippi valley and parts of the south, also parts of Western Canada, a very large mink is found, but running quite pale, and the fur somewhat coarser than the northeastern varieties. Again, on parts of the Pacific Coast, a very small and poorer quality are found, and the mink from the lower Yukon River of Alaska are said to be of very poor quality. One or more varieties are found in almost every part of the United States, Canada and Alaska. Wherever there is running water their tracks may be seen; but they seem to prefer the smaller streams, as a rule, and they will be found as plentiful in the thickly settled parts as in the wilderness. Mink are great travelers, but each individual animal has his regular route and seldom ventures far out of his course. While they travel streams and lake shores as much as possible, they do not hesitate to leave the stream and cut across country in order to reach some other water-course. During the mating season they also wander away from the streams more than at other times. While they are always found in the neighborhood of fresh water, they are not a water animal, and in following a stream, always run on the bank, but usually as near to the water as possible.
