[a]Fig. 24.]—Skin-Scrapers, about one-fourth actual size.
All skins larger than a gray wolf, whether they be fresh or dry, need to be stretched on a beam, and pared down with a sharp draw-shave that has adjustable handles. This useful instrument can be bought at any large hardware store for $1.25. Keep it thoroughly sharp. The beam should be about seven feet in length, and six by three inches in size, and laid flat. One end of it is to be bolted firmly down to your bench by two movable iron bolts, and the half which projects beyond the edge of the table must have both of its upper edges rounded off so that it will represent half a cylinder with the convexity uppermost. The table itself must be fastened securely in place. Throw the skin over the rounded end of this beam, drive a stout "scratch-awl" through it, just beyond the reach of your arms, stretch and flatten the skin upon the beam, and with the draw-shave carefully shave down the entire skin until it is thin enough.
Be very careful at first, until your hands acquire skill, or you will cut through the skin, which, in the case of an animal like a hair seal means an unsightly, permanent defect. Do not be afraid of paring a skin too thin so long as you stop at the roots of the hair.
Of course you can not pare down the skin of the head and feet with the draw-shave, and these must be treated with the knife and scraper. The skin of the head of every mammal must be pared down and scraped particularly thin all over, especially the eyelids, lips, and nostrils, so that when these parts are backed up with clay you can model them into exquisitely fine form and expression. If you slight the skin of the head, good-by to all expression; you will merely be able to "stuff" it, and that is all. If its features look coarse, uncouth, and wooden, it will probably be because the thickness and inelasticity of the skin defies your art.
Of course the joints of the feet must be got into working order. The leg bones and skull require to be thoroughly scraped and cleaned, and the skin itself worked up as nearly as possible to the condition of a fresh subject.
Carving Wooden Skulls and Leg Bones.—It is absolutely essential that every mammal to be mounted should have a skull, and all save the smallest should have leg bones also. If the skull and leg bones that belong in a skin are missing, I invariably carve others of the same size out of soft pine to replace the lost members. These bones are imperatively necessary to give shape and length to the various joints and angles of the limbs, to shape the head, to give a foundation for the attachment of wires, and to build upon generally. Very often the skull of an animal is of such value to science that it must be kept out of the skin at all hazards, and exhibited separately. Then it must be duplicated in wood.
Every mammal taxidermist must learn how to carve wooden bones, and the quicker he becomes expert at it, the better. Very few tools are required, and these are as follows: A small hatchet, a pair of 8-inch calipers, a pair of 8-inch dividers, gouges of three sizes, 1/4, 1/2, and 3/4 inch; chisels of about four sizes between 3/8 and 1 inch, a draw-shave, a spoke-shave, a good sharp pocket-knife, and the usual supply of boring tools.
