The eyes I prefer to insert in the larger birds after the specimen is dry, as then any little fault in the shape of the head is easily rectified through the orbit, the eyelid, of course, being previously relaxed (with cotton wool dipped in warm water) to do this and to receive the artificial eye.
Waterton's method of setting up birds may be dismissed in a few words; it is impracticable for anyone but an amateur who has unlimited time at his disposal, and who does not object to spend about a couple of days over one specimen, and who has also ample room for the large collection of different-sized boxes he must accumulate.
In using the corrosive sublimate the student will do well to carefully read the chapter on Preservatives, and then make up his mind. I may here mention, however, that I should not advise anyone to work on a bird previously saturated with a solution of corrosive sublimate.
It has been said, De mortuis nil nisi bonum; but, while fully acknowledging the force of the remark, as also the great scientific attainments and love for natural history which distinguished the illustrious traveller, I cannot allow anyone who reads his entertaining works to be misled into wasting time in an unprofitable manner.
Another way of setting up a bird may be described as follows: Provide yourself with four wires — two of which are for the legs, a long one for the body, and a shorter one for the wings; let us suppose we have another starling in front of us. For this bird take a suitable piece of wire about three inches long (pointed at both ends), and bend it down at each end for the distance of an inch, which of course leaves one inch in the middle at a right angle to each end; this is called the wing-bearer. Then place a little piece of tow inside the skin to fit along the back, and on to the top of this lay the wing-bearer, pushing the pointed ends down and into the hollows of the wing-bones (which must be left nearly their full length to admit of this).
Next take the body wire, also sharpened at both ends, and a little longer than you require, and at a sufficient distance from one end form with the pliers a loop similar to Fig. 1, so that it comes about the centre of the projected body; one end will thus be much longer from the loop than the other. Run one end (the longest) right up the body to come out at the crown of the head (the head itself being previously stuffed), push it through a sufficient distance, so that the looped end falls within the incision of the skin; so soon as it is passed inside pull the looped end down, and push its point through the root of the tail; the loop should now, if accurately calculated, come just in the centre of the body incision.
Pack underneath the wire at all points with little pieces of finely cut tow, not forgetting the neck. The wire should now be protected from touching the bird on its underside. Now take the leg wires, point them and pass them up the legs as before described; when they appear within the skin by the side of the legs, push the ends of each one through the little loop on the body wire, and by the aid of the small pliers and your finger and thumb twist them tightly up or down the main wire. If properly done, the bird should be capable of being lifted by one leg wire and should feel perfectly stiff and firm. Proceed by the addition of cut tow to gradually form the body, which, when arranged to your liking, sew up.
This, in contradistinction to the other method, is called the soft body, and is not a plan which I at all recommend. Sometimes a cork is pushed on at the main or body wire to act in the place of the loop; the leg wires are then pushed through and clenched on the other side, and the skin is filled with cut tow as before.
Another system of forming an artificial body for a bird is by means of "peat." [Footnote: "Peat" is compressed vegetable fibre cut from old bogs, and is sold by the dealers, in dried cakes about 1 foot long by 6 inches by 2 inches.] Having provided yourself with one of these bricks of peat, you cut it with a sharp knife to as near the shape required as possible, having the natural body before you as a guide, finally inserting it in the bird.
My objection to the use of peat for this purpose is, first, the dust and dirt caused by the waste pieces; and, secondly, the fact that birds mounted on this system have a tendency to look "wooden," as, unlike a body formed of tow, that made of peat is stiff and unyielding, and, therefore, after it is once in the skin, it cannot be pressed into shape where defects appear, and is of course not so easily altered. After a long and patient trial of the peat body, I have become convinced of its many disadvantages, and have of late years returned to my first plan — the body made of well wrapped tow — nor do I think anything will compare with it, for the reasons above stated. Peat in the case of very large birds (ostriches, etc..) and mammals is useful, but for the ordinary run of birds I decidedly veto its application.
