368 The Book of Woodcraft that is attached to the skin, and dry in the shade. In damp weather it is sometimes necessary to use powdered borax to prevent the remaining flesh from decomposing. Never put arsenic or salt on a skull. Remove all fat and tags of flesh that ^adhere to the skin. In cleaning off blood or dirt that may have soiled the hair an old toothbrush and a liberal supply of corn- meal wiU be found serviceable. Poison all parts of the skin with dry arsenic (or better still, with a mixture of powdered arsenic and alum in the proportion of four parts arsenic to one part alum), being particular to put an extra supply in the feet and tail. Put a wire in the body, letting it extend to the extreme tip of the tail, but be careful not to stretch the tail. Use annealed iron wire of as large size as will fit easily into the tip end of the tail. In rabbits, foxes, and wildcats put wires in the legs also. Stuff the skin to nearly its natural size with cotton or tow (never use wool, feathers, or other animal substances) ; sew it up along the belly, and place it flat on a board to dry (belly down), with the fore legs extended in front and parallel to the body (i. e., not projecting sideways), and the hind legs and tail directed backward. The accompanying cut (Fig. i) shows the appearance of a well- made skin. Attach to each skin a label bearing the same number that is given the skull. On this label should be stated the sex, locaHty, date of capture (name of month should always be written in full), and name of collector. All skins should be thoroughly dry before they are packed for shipment. They should be carefully wrapped in cotton and packed in small wooden boxes. Cigar-boxes do very well for the smaller species. Washington, D. C, March, 1889.
