When the filling is all placed, sew the abdominal incision neatly up, beginning at rear end always and going forward. Wax the thread. In a hunched together position, middling long stitches may be used. In a straighter pose shorter stitches should be used.
Now, when the body is sewn up cover the specimen with paper and a damp cloth to prevent drying while a small batch of compo. No. II is prepared for finishing feet and head. Returning to the specimen with this, slightly moisten the wrapping on the bones of the feet and apply a bit of the compo. at front and in the sole of each foot. This cements the toes to the foot and fills the pads.
After this is done sew each foot up neatly, beginning at toes and working toward body. If toes were large and required splitting and removing of toe cords, replace the cords with bits of small rope or soft twine and sew toes up neatly with short stitches. It is best to use a round needle and black thread, well waxed for this work.
The specimen is now ready to place upon its base, perch, or stand. With the approximate position shaped, mark the perch for wire holes by holding specimen over it and indicating places where wires come, by scratch or pencil mark. When holes are drilled and the specimen wired into place, take a strong fur needle set into a handle and by working and compressing with the fingers and jab-lifting with the needle, finish shaping and positioning.
Hold in hollow of flanks by sewing through here with long needle and strong cord, heavily knotted for the first hold. Finish this sewing with a knot drawn down into the fur under the thumb. Arrange the fur over all stitches by picking it free with tweezers.
With the body finished, take up filling and finishing the head with the compo. First work compo. into the ears and pinch them out thin and into their natural shape, then cover the entire face under the skin with compo. Fill eye sockets and set eyes as second step. Lastly fill the nose and lips and model them firmly upon the jaws. In all mammals cover the teeth well with the lips. Even in a muskrat the teeth do not ordinarily show at all. Also avoid getting the lips, nose, and whisker base too full. Set the tail into easy normal position, pin toes to grasp the perch or set well upon the ground and inspect the body to see that no hollow or bumps remain in the filling where there should be perfect smoothness. Remove such of these as persist with the handle-held fur needle and then set the specimen in a well ventilated place to dry.
The principal point in preparing thin or stretchy small mammal skins for mounting is to leave the membrane of skin-muscles on the body skin. This holds a flabby skin in shape and lends strength to a frail one. In spite of this the legs of most wild rabbits must be handled very gingerly, as they have no lining membrane like the body. For finishing mouth, nose, and eyelids of mounted mammals, melt a little refined beeswax in a metal vessel. While the wax is hot (don't allow it to smoke), stir in a little tube oil color (black or brown for most mammals; color to nature for birds with highly tinted eyelids). Mix the wax and color thoroughly with a flat bristle brush. Afterward the brush may be easily cleaned of the wax by breaking it up with alcohol, when it has cooled.
Next draw some wisps of fine, long-fiber cotton through the melted wax and lay them quickly flat upon oiled paper to cool. For lips of mammals cut narrow strips of the wax. Heat an upholstering spindle and with it repeatedly heated, melt the wax and cotton into crease of closed lips. Melt thin, flat pieces of the wax into depth of nostrils and very narrow strips in eyelids.
When all the wax is placed, model it into shape with a smooth, wedge-ended bit of pine wood. To clean out wax that ran into the hair by melting, apply alcohol with a bit of cloth, scratch the waxy hair loose with finger nail and rub the crumbled wax out with the bit of alcohol dampened cloth. This leaves lips, eyelids, and nostrils neatly finished. Apply thin varnish to nose, edge of eyelids, and bare parts of lips that show. For mounting a mammal with open mouth, follow same note given in making a whole head for rug.
To make a small mammal cabinet skin, remove the skin as for mounting except that legs are severed at elbow and knee and soles of feet are split only to allow of poisoning.
