[a]Fig. 4.]—A Model Mammal Skin.
Having wrapped the leg bones enough fairly to replace the flesh, turn back the skin of the leg until it comes right side out again, adjust the skin neatly, and make the member as shapely and natural as you please.
The Skull.—There are two ways of disposing of the skull. The universal custom has been to replace it in the head, with a little filling in the cheeks and orbits, the lips neatly adjusted on the teeth, and the eyelids also in their place, half open. This makes the best looking skin, and unless you wish to study the skull, is the best method to follow. For skins that are specially designed for study, the plan lately adopted by the curator of mammals of the National Museum is an excellent one. It is to remove the skull entirely from the head, and in case of all mammals smaller than a coyote, put it in the centre of the body, with the filling, in the line of the seam along the belly, so that by cutting a few stitches in the dry specimen it may be readily taken out at any time. The advantages of this arrangement are obvious.
The Tail.—The tail must be disposed of according to its character. If it is long and slender, take a small wire, wrap it with tow or cotton cloth, so that the skin cannot touch the iron at any point, insert it in the tail and sew it up with a few long stitches. If you have not the means wherewith to do this, whittle a slender stick to a point, and insert it in the tail from within two inches of the body out to the tip. If the tail is large, and has been split open for its entire length, it can be left flat.
Filling.—Begin at the head and fill out the head, neck, and body to about the natural size of the animal when alive, but no larger. Better leave it too small than fill it too full, and stretch the skin out of proportion. With needle and thread sew up the skin to give it a neat appearance, beginning at the throat. Comb and brush the hair so that it will lie naturally, and show its texture and colors to the best advantage. Take a stitch also in the centre of the lips to hold them together.

Shaping.—The ends to be sought in laying out a skin to dry are, to have it take up a limited amount of space in a drawer, to have all breakable points protected, and at the same time to have all parts of the specimen accessible for examination. The shape of a dry skin, therefore, must depend upon its character. The handsomest collection of small mammal skins that I have ever seen is that of Dr. C. Hart Merriam, Chief of the Bureau of Economic Ornithology and Mammalogy, Department of Agriculture. Although it is purely a private collection, it contains at this date 5,750 skins. Dr. Merriam's method of shaping a skin is certainly, so far as looks are concerned, the best yet devised. Fig. 4, on the opposite page, shows it perfectly. The tail is wired, and extends straight out behind, lying between the hind legs, which also extend directly backward. The forelegs are drawn forward just far enough apart to allow the head to lie between them. The skin is well shaped, and lies flat upon the belly, with all the members resting down upon the bottom of the drawer.
With specimens having long tails this arrangement is open to one objection. In the rough-and-tumble experiences that collections made in the field almost inevitably go through before they reach safe anchorage in the museum, a long tail sticking straight out for its full length is very liable to suffer damage in various ways, especially at the tip. For this reason I always bend the tail down and lay it along on the belly, with a stitch or two to hold it there, safe from harm (Fig. 5). And with such animals as monkeys, sloths, cats, etc., having long and slender forelegs, I always place those members close alongside the body, instead of extending them their full length toward the front.
