Part 13

The most pert and characteristic att.i.tude of a squirrel is sitting up on its haunches, either on the alert, eating something held in its paws, or, perhaps, washing its face with its paws. This att.i.tude is rather difficult to get, but it is well worth trying for. Bend each hind leg at the knee until the thigh touches the calf and rests upon it. Bend the ankle-joint until the foot makes an acute angle with the calf. Make a very decided curve in the backbone, so as to throw the body well forward between the knees, which must come nearly opposite the centre of the body. Push the hind legs up into the body so that the squirrel can sit upon his tail.

The elbows drop down until they almost touch the knees, which is partly accomplished by curving the back. Just below the shoulders the backbone must be curved, to throw the head and shoulders up, and hold them well erect. Give the head the pose you wish it to have, slightly turned to one side, let us say.

The next step, a very important one, is filling the body. If you do not do it intelligently, your squirrel will need to find a grave in the ash barrel. The mechanical part of this filling process is exceedingly simple, and everything, or nearly everything, depends upon how much you know of the anatomy of the animal before you. This is a private matter between yourself and _nature_. Your hand will nearly always be able to keep up with your eye if you give it a fair chance.

With your long forceps, which work like a dextrous thumb and finger eight inches long, pick up the chopped tow, and little by little insert it in the skin where it is needed. First fill out above the backbone until you get the desired outline, in profile, of the back and shoulders from tail to head. Then fill out the shoulders and form them properly. Fill in the neck, first around the base of the skull, and sew up the neck skin from the end of the cut downward for about two inches, and without cutting off your thread insert more chopped tow in the neck and shoulders, packing it firmly, if you have the proportions right. Do not allow the tow to roll up into wads and make the skin full of hills and hollows on the outside. The pressure of the tow on all points of the skin should be the same, and the filling must be packed firmly and evenly, so that the finished animal will keep its shape tenaciously in the struggle for existence, and not collapse at a firm touch.

One secret of success in filling the body lies in gradually and equally filling out the _entire body_ to fair proportions before finishing any one part. Give the animal its exact att.i.tude, then proceed. If there is an apparent lack of skin at any particular point, attack that first, and fill it out. You will soon find how easy it is to draw skin from one part of the body to another by judicious filling.

Having finished the neck and shoulders, leave that part and go to the haunches. Fill around the base of the tail, the hips, the upper part of the thighs, and the abdomen. Be careful to make both sides alike. Commence at the root of the tail and sew up the opening for about two inches, without catching the hair in your st.i.tches, after which you may bore two small holes in a pine board, the proper distance apart, pa.s.s the two hind leg wires through, and set the little animal up. This is only a trial trip, and if you find the feet are not the proper distance apart (or the squirrel does not walk properly, if you have put him in a walking att.i.tude), or does not sit properly, take him off the board and remedy the defects. When you have corrected his att.i.tude, proceed with the filling, sewing up from both below and above, until the body is properly shaped, filled full of tow, and the opening entirely sewn up.

Now comb the tow out of the damp fur, and, if it is dirty, wash it with washing soda, soap and water until it is thoroughly clean. Place the animal upon its board pedestal, and correct the att.i.tude with the utmost care before you bend the wires up underneath the board and clinch them fast. If the specimen is even a moderate success thus far, we will go on with it.

If the animal you are mounting is a tree-climber, and you wish to mount it upon a tree limb, select one for the purpose, and, according to your desire to have it nearly perpendicular, slanting, or horizontal, saw it off at the lower end, plant it firmly upon a rough board pedestal, and fasten it by putting two long, stout screws through the board and up into the base of the branch. Put your specimen upon the branch as nearly in position as possible, mark the places where the holes should be bored, and bore them with a bit of the proper size. You can then run the ends of the leg wires through, draw the feet down closely, and clinch the wires on the opposite side.

As soon as the little animal is firmly fixed on his temporary pedestal, or his branch, which must be permanent, we are ready to give the final touches to the body. We will, with thumb and finger, press in the shoulders if they are too high or wide, flatten the body by pressure if it is too round on the sides, and emphasize the undulating outline of the sides also by pressure. If there is a hollow spot where the surface should be smooth, thrust a sharp awl through the skin, catch some tow on the point of the awl, and, with a sharp lifting motion, pull the fibre up until it fills out the hollow. If there is a lump of tow under the skin, making an unsightly hump, thrust the point of the awl through into it, and spread it out underneath until the skin lies flat. It is often necessary to work all over the body of an animal with the awl in this way.

We have now to finish the head. With the cutting pliers, cut off the end of the body wire close up to the skull, so that the end will be hidden. Adjust the skin so that it fits naturally and easily on the skull and around the mouth, and see that the eyes come over the centre of the orbits. If the clay which was put upon the skull does not fill out the jaws and sides of the head quite naturally, push in a little chopped tow until the proper form is obtained.

[Ill.u.s.tration: FIG. 27.--The Finished Specimen.]

Avoid getting one jaw fuller than the other; it is only boys and men who chew tobacco who have cheeks that are not bilaterally symmetrical. Avoid getting one eye too far back, forward, up or down, but match the one that is correctly placed.

Fill in the end of the nose, the lips, and the chin with clay, fold the lips naturally and press them into place. If the skin around the mouth is not unnaturally drawn back, the lips will stay in place, and dry there without any fastening. If the skin is drawn too far back, the lips must be pinned in place until they dry. The advantage in using clay for filling out the head is that it enables you to press the skin down upon it and mould all the parts into their natural shape and size, without giving to the head that unnatural, puffed out, _stuffed_ appearance, which is almost unavoidable when tow only is used.

Introduce clay at the eye opening until the addition of the gla.s.s eye inside will make the organ sufficiently prominent. Insert the gla.s.s eye edgewise through the opening, turn it in position and embed it in the clay.

With a large needle, or your awl, adjust the eyelids upon the gla.s.s, and if the eye is not right, work it into its proper position. Adjust both eyes alike, and, above all, see to it that they both look at the same point, be that point real or imaginary.

The same amount of iris must show in each eye, and the position of the pupils must correspond exactly. Do not make them unusually staring, as though about to burst from their sockets. It is the eye more than any other one feature that gives any animal, living or stuffed, its expression, and this is due entirely to the arrangement of the lid and brow. The eyeball has, in itself, no more power of varied expression than a gla.s.s marble; therefore the facial expression of a mounted animal is wholly under the control of the taxidermist, provided he takes the trouble to procure good gla.s.s eyes of the right size and quality.

Unless the ears of your specimen are very small and insignificant, it will be necessary to cut two pieces of thin card-board the shape of each ear, but larger, and after getting the ear in position, pin it between them, so that it will be held in a natural position and good shape until it dries.

Do not thrust the pins through the ear, but through the card-board around the edge. The last thing is to arrange the toes and feet naturally, and pin each toe in place until it dries. Since our squirrel is to be holding a nut, we will cut off the foreleg wires, all but half an inch, and bring the paws close together at the proper elevation. We must now drill two small holes in opposite sides of a hickory nut, force the wires into them until the nut rests nicely in the paws, and there let it remain. If necessary, we will tie the toes in position around the nut until they are dry. It is a common fault with beginners in taxidermy to slight the toes of their specimens, both birds and mammals, and, as a result, all such specimens have a slovenly, tramp-like appearance.

Nature alone can tell you how to pose the tail to represent the state of the animal's feelings. Try to look at your work with the eye of an artist, a.n.a.lyze it, and catalogue its faults, so that you will be sure to avoid them in the next specimen.

If the hair needs no more washing, comb it out carefully at the last moment, and set your specimen on a shelf to dry, out of the dust if possible, and out of the sunshine, and watch it while it is drying to see that the head and feet dry in good shape. At the end of two weeks, or perhaps three, the little mammal will be dry and hard, and ready for the last touches. Pull out all the pins which have been holding the toes, ears, lips, or eye corners in place, and if they leave any holes, fill them up with putty. I have not told you how to stuff a head with the mouth open, and model the soft parts in papier-mache and wax, because you will hardly want to try anything so difficult at present, and it involves processes which cannot be described within the limits of this chapter.

When your mammal is quite dry, dress the fur with a fine comb and brush, and beat it with a small piece of whalebone or a little switch, to make it stand out from the skin, full and fluffy, as in life. This end must be accomplished, no matter how long it takes.

Procure some tube colors, oil and turpentine, equal parts, and a small sable brush, with which to tint the eyelids and the end of the nose their natural color. Put a little varnish and turpentine, equal parts of each, on the toe-nails, and, in short, do everything you can that will give the specimen the look of a living animal. If it _looks stuffed_, put it in the darkest corner of your cabinet, and try another. The gla.s.s eyes must be cleaned with great care, and polished with a soft cotton rag until they glisten.

At the last moment change the rough board pedestal for a permanent one, either of black walnut, polished, or ash, planed and sand-papered very smooth, and covered with two coats of sh.e.l.lac. If you have perched your squirrel on the top of a small stump, sawed off square at the bottom, or upon a large branch, with a section of the trunk serving as a base, of course no artificial base is necessary. Artificial branches for mounted birds are bad enough, but for mammals they are altogether too bad, and should never be used.

In conclusion, do not expect that your first mammal is going to be an overpowering success. Do not take a cat for your first subject, for a cat is the most difficult of all small quadrupeds to mount successfully. A tough old squirrel is the best thing for you to wrestle with until you have learned the method thoroughly.

EXCEPTIONAL CASES.--There are certain cla.s.ses of small mammals whose skins should not be put through the salt and alum bath, if possible to avoid it, for several reasons. These are the young of the smaller mammalia, especially such as rabbits, squirrels, and other familiar forms. It is by far the best plan to mount all such skins as soon as they are taken off, without wetting the hair, and using dry a.r.s.enic and alum, equal parts, to preserve and poison them. The bones of young animals become quite soft in the bath, and the hair is difficult to dress to look like life. The fur of a rabbit is the meanest fur in the world to comb out and dress to look fluffy and immaculate after it has once been wet with salt-and-alum water.

Mount them without wetting when you can, only _poison them well_ against moths. Alcohol is far preferable to the bath for the skins of such species as the above, and, as our English cousins would say, is "not half bad."

MOUNTING BATS.--Having tried all known methods of mounting and displaying these pestiferous little subjects, I finally evolved an arrangement which I now conceitedly believe is the only satisfactory solution of the difficulties they present. My plan is to mount the bat without any wires, save in the legs of the larger species, and when finished lay it on its back on a smooth board, spread the wings, put pieces of pasteboard over the membrane until all is covered, and pin them down. Of course the wings must be in perfect position. When the specimen is dry, apply some royal glue of the best quality to the back of each wing, and stick his batship permanently on a strip of thick plate gla.s.s, which has been prepared previously by being cut to the proper size, and ground on the edges.

[Ill.u.s.tration: FIG. 28.--Author's Method of Mounting Bats on Gla.s.s.]

The accompanying cut (Fig. 28) was drawn from a specimen as exhibited, omitting the label. The advantages of this arrangement are as follows: It shows the specimen perfectly on both sides; the wings do not warp and shrivel up; it is possible to repair breaks in the wing membrane, and the most delicate specimen is well protected. The strip of gla.s.s stands on edge in a deep groove which has been cut to fit it tightly in the top of a flat, narrow pedestal having the usual moulded edge.

FOOTNOTE:

[8] If you can not procure annealed wire, take hard iron wire, heat it to redness, and as soon as it reaches that state remove it from the fire and allow it to cool slowly.

CHAPTER XVI.

MOUNTING LARGE MAMMALS.--ORDINARY METHODS.

SECTION 1. LONG-HAIRED MAMMALS OF MEDIUM SIZE.--_Examples: Wolves, certain dogs, large apes, baboons and monkeys; the smaller bears, hair seals, all long-haired quadrupeds from the size of the fox to the Newfoundland dog; also, all old dry skins of mammals between the two sizes mentioned._

While it will be advised in Section III. of this subject to mount _short-haired_ skins of the above sizes upon clay-covered manikins, it is very often an impossibility to pursue this course with a dry skin, no matter what its pelage may be like. Dry skins more than one year old are usually so shrunken, hard, and inelastic, that in circ.u.mference they are one or two sizes smaller than life, and it is very often impossible to stretch them sufficiently to make them fit over a manikin of the right size. The only way in which enough power can be brought to bear upon them to force them to stretch to their proper size in neck and body, is to fill them with straw, and ram it so hard that the skin is forced to stretch.

Even if you fill a shrunken body so full that it will stretch no more, if you keep it thoroughly moist, or even wet, in wet cloths, and return to the charge next day with more straw and muscle, you will find that the skin yields a good deal more, and perhaps reaches the right size without further protest. Very often this is the only treatment that will save an old, dry skin from becoming a total loss. In all such cases _fill out the worst shrunken parts first_, to make sure of conquering them, and leave the less difficult portions to the last.

The chief differences between the method described in the previous chapter for mounting small mammals, and that for the subjects included in this section are simply these: (1.) The larger animals require leg wires or irons that are too large to be bent at will and twisted together. (2.) Where rods are used, a thread must be cut on the lower end of each to receive a nut under the pedestal, because leg rods can not be fastened in any other way. (3.) A stout wooden bar must be used in the body for the leg, head, and tail wires, or irons, to run through, and upon which all these can be stapled down firmly. (4.) For various reasons, it is best that all these animals should be filled with straw by the old process of stuffing.

To mount a specimen belonging in this section, proceed precisely as directed in the previous chapter, with wiring and making each leg, _except_ where the specimen is so large that it requires rods for the legs instead of wires. It is only the larger and heavier animals of this section, viz., the wolves, large dogs, large kangaroos, anthropoid apes, and the like, that require rods instead of wires. For your foxes, baboons, and small kangaroos, you can use wires of the large sizes, of about the same proportionate length as for your squirrel. In getting out the rods for the legs of your large specimens, use Norway iron, because it is toughest, and proceed as follows:

Decide upon the att.i.tude of your specimen, then lay the bones of each leg in its intended position on the table, take a straight wire of large size (No. 9) and bend it to fit the back of the leg bones, precisely where you wish your rod to go. Leave an end about two and one-half inches long, projecting _straight downward_ from the centre of the foot, to go through the pedestal and receive a nut underneath. Cut a thread on this lower end, and fit a hexagonal nut. For the hind legs, let the upper end of each rod project beyond the upper end of the femur for a distance equal to about two-thirds the length of that bone. The irons to support the head should be two in number, and should be long enough to reach from the end of the nose to the centre of the body. The tail iron will be regulated by circ.u.mstances.

THE HAND OF AN ANTHROPOID APE.--It nearly always happens that every skin of a large gorilla, chimpanzee, or orang utan is totally dest.i.tute of bones.

Now the hand of such an animal is a very important feature. Do not attempt to make it with wires and tow alone, for if you do, the fingers will be semicircles, resembling the half of an over-brown doughnut. Each joint must show _an angle_, and each finger be _flat_ on the inside. The accompanying cut (Fig. 29) shows how to make the hand of an anthropoid ape so that it shall be as natural as life. The wooden bones give the proper angles at the joints, and the tow-wrapped wire underneath gives the finger its proper breadth. When all is ready, cover each finger manikin with clay, _make the palm hollow and flat_, and let the end of the iron rod come out in the centre of the palm. This method gives a hand that is beyond criticism. For hand and foot studies of apes and monkeys, see "The Standard Natural History," vol. v., page 512.

[Ill.u.s.tration: FIG. 29.--Artificial Skeleton for Hand of an Orang Utan.]

The following animals, when of adult size, require leg supports of the following sizes: Large foxes, No. 8 wire; olive baboon, No. 5 or 6; small kangaroo, No. 4 to 6; wolverine, No. 6; coyote, 1/4 inch rod; setter dog, 1/4 inch; peccary, 1/4 inch; great ant-eater, 1/4 inch; gray wolf, 5/16 inch; giant kangaroo, 3/8 inch for hind legs; harp seal, 3/8 inch.

Having made the legs complete, lay the skin upon its back, with the legs spread out, make the irons or wires cross each other as shown in the accompanying figure (Plate VI.), and then hew out a piece of tough wood of the general shape and proportion as that shown in the cut. Let this be as small as practicable to avoid splitting when the irons are stapled down upon it. Round off the corners and the ends, so that you can easily work all around this wooden backbone, when filling the animal. Now lay this piece of wood in the skin, upon the crossed leg irons, mark the points at which the irons need to pa.s.s through it, and bore holes accordingly, _slanting_ each hole through the stick, for good reasons. The next step is to pa.s.s the irons through these holes (by bending them a little, and straightening them afterward) and when all are through, adjust the legs so that there is plenty of loose skin in the body, both in length and breadth.

Remember that the stick is to be in the centre of the body, not the top.

When the adjustment is complete, bend the end of each iron sharply down upon the stick, and staple it down with the utmost firmness.

Next pa.s.s one of your neck irons through the skull from back to front, boring a hole at the back for the purpose, so as to make the end of the iron pa.s.s out at the nasal cavity. Replace the missing flesh of the skull with tow or excelsior, bound down with thread, cover all with clay, poison the inside of the head and neck skin with a.r.s.enical soap, insert the skull in the head, and fasten the lower end of each neck iron firmly upon the centre stick.

The tail must now be made, but it is wise to fasten the tail iron so that it can be made to slip out or in, until it is known precisely how long it shall be, and then the end may be fastened securely with staples. Now bend up the legs into position, and give the animal its att.i.tude. Procure your pedestal, or limb of a tree, and place the animal in att.i.tude upon it; mark where the iron supports are to pa.s.s through, bore the necessary holes, and see if the animal will stand just as you wish it to. If not, work at its legs, and bore new holes until it does; then take it off, poison the inside of the skin liberally with strong a.r.s.enical soap, and proceed to stuff it with straw, or chopped tow, or excelsior if you prefer that, but I never do. For my own use I prefer soft straw, chopped fine.

Fill the neck first, using your wooden filler, then the body. If the body threatens to be too small, fill that first. Before going far, fill out the hind-quarters properly. Work on the body _all over at the same time_, and do not finish one-half of the animal before you have touched the other half, for this course would get you into endless trouble.

[Ill.u.s.tration: PLATE VI. INTERIOR MECHANISM OF A HALF-MOUNTED WOLF.]

Having filled the body full, and shaped it the best you can, and sewn it up at all points save two,--a hole between the forelegs and one under the tail,--now put it in final position on its pedestal, and fasten it there.
