The boy trapper must know how to take the skins from the animals he traps, and how to treat them to preserve their beauty and value. The skin should be taken off before it becomes tainted, and with greatest care not to injure it. Some skins are exceedingly tender. Be careful to remove bits of fat or flesh; left to dry on the skin, these detract from its value.
No artificial dressing is needed to cure or dry a skin. The fresh skin should be tacked to a smooth board or drawn over a stretcher, fur side in, so that the air can get at it freely. It should not be put in the sun, or rain, or artificial heat.
When thoroughly dry, the skin is ready for market or it may be tanned at home. A boy fortunate enough to obtain a valuable pelt like that of marten, mink, or otter, will certainly want to try his hand at tanning. You want first to be sure to use a mixture which will not injure the fur but will fix it more firmly in its place. Never put any dressing on the fur itself. You also want the skin to be soft and pliable so that it can be made up into some form of garment. The following directions are adapted from "The Tricks of Trapping" by W. Hamilton Gibson, a reliable source of all trapping lore for American boys: "After every particle of loose flesh and fat is removed from the skin, it should be soaked for a couple of hours in warm water. While waiting, prepare this mixture: Take equal parts of saltpetre, borax, and sulphate of soda. Mix with enough water to make a thin batter. Paint the wet skin over thickly on the flesh side. Fold the skin flesh side in and lay in an airy place, for twenty-four hours.
"On the following day prepare a second mixture consisting of two parts sal-soda, three parts borax, four parts castile soap. Melt these together over a slow fire. Apply this mixture in the same manner as the first, twenty-four hours later. Fold skin as before and leave another twenty-four hours. Make a third mixture of equal parts of common salt and alum, dissolved in warm water and thickened with coarse flour to the consistency of thin paste. Allow this to dry on, then stretch the skin lightly and scrape off the hardened paste with the bowl of a spoon. Sometimes a second or even a third treatment with the last mixture is required to make the skin absolutely pliable, after which it should be finished with sand-paper and pumice stone. A skin thus dressed should be soft as velvet. The alum and salt set the hair securely."
