If otters are kept in an enclosed pond, it will be necessary to keep them supplied with food, and perhaps the best way would be to keep the ponds stocked with live fish and frogs. With the beaver the matter of providing food is more simple, as it will only be necessary to make the enclosure where their natural food is found in abundance. CHAPTER XII. KILLING, SKINNING AND STRETCHING. When "killing time" comes, care should be taken to not frighten the animals left for breeding purposes more than is absolutely necessary. All animals that are tame enough should be driven into a separate enclosure and out of sight of the others before being killed. Perhaps as good a method of killing as any is to use a good club, striking on the head just over the eyes or ears. The above method is not for skunk, as they should be killed without the enclosure becoming so strongly scented. A pole several feet long with a strong loop on the end can be slipped over their head and well back on the neck. The animal can now be lifted clear off the ground and carried wherever the killing is desired. If the killer does not mind a little perfume he knocks them on the head, or if a barrel of water is handy they can be drowned and few scent. The drowning, however, is not recommended, as it takes the fur hours to dry and is therefore extra work. Some even claim that the water spoils the luster of the fur to a certain extent. Some animals, such as coon and skunk, do not leave their dens during severe weather, so that it is advisable to begin selecting those that are to be killed days and even weeks in advance of the time decided upon. These should be placed in an enclosure or pen by themselves so that the remaining ones will not be disturbed. Even those animals that come out to their feed regularly during the cold days should be handled in a similar manner so as not to disturb those to be kept. The animals that are to be kept for breeding purposes need not be fed so heavily during the winter months or after those that were intended for market have been killed. Of course in the spring after the females have young, they must be fed heavily. Some raisers, as soon as the young are weaned, select those that are to be killed the coming winter, keeping them separate from the breeding stock so that they can be fed properly. That is a great saving of food, as those for market should be fed much more than the breeders at this season--say during the months of September, October and November. Much importance should be attached to the skinning and stretching of all kinds of skins so as to command the highest commercial value. The otter, foxes, marten, mink, opossum, civet and skunk should be cased, that is, taken off whole.
