CLEANING BIRDS' SKINS, etc.. — Formerly, it appears, the orthodox method of cleaning birds' skins was by the application of water and plaster of Paris. When it was wished to remove blood, or other stains, from a white or a light-coloured bird, this was effected by means of a soft piece of wadding saturated with warm water, and then rapidly and lightly applied to the stained part, followed by plaster of Paris dusted on the way of the "grain," and allowed to remain on the specimen until perfectly dry, when it easily came off in cake-like pieces, leaving the feathers thoroughly cleansed of all impurities. If the wadding became overcharged with blood, it was, of course, changed from time to time before the plaster was thrown on.
Though this method does very well for blood stains of a recent date, it will not remove grease or the stains from old skins. This was always a weak point with the taxidermists of yore, who used, with very meagre results, turpentine and plaster of Paris to clean their skins. This went on for many years, and, though an unsatisfactory state of things, had to be endured, as nothing better was known.
Some few years ago "benzine collas" was introduced, and the taxidermists were not long in finding out its valuable properties for feather cleaning. "Benzoline" (Benzol, or Benzine C6H6), then came into more general use, and was, of course, found to have all the properties of the so-called "benzine collas." This discovery, we may say, completely revolutionised the art of feather cleaning. It served equally as well as the other preparation, and its superior cheapness placed it within the reach of everybody. The cleansing property of benzoline is still somewhat a secret out of the profession, and is really worth, as a matter of business, all the money which is sometimes asked for divulging it to an amateur.
When, therefore, you have a bird which is greased, or stained with greasy dirt, etc.., wipe it down the way of the feathers with a piece of wool saturated with common (or French) benzoline, using from time to time fresh wool as the other becomes soiled. When the feathers are well damped, cover the newly-cleaned part with dry plaster of Paris, allowing the bird to remain from one to two or three hours, at the expiration of which time take it out, dusting the waste plaster off with a soft bundle of feathers, Do not be alarmed if the bird looks somewhat miserable at the outset, but be sure that, if the plaster is dusted on the way of the feathers, all will come out right.
Blood, whether fresh or old, is best removed by warm water as just described, and the feathers then carefully wiped down with benzoline, before putting, on the plaster; this obviates the roughness often observable in water-cleaned birds. [Footnote: The American publication, "Science," points out that the addition of salt to the water cleanses blood from feathers, by preventing the solution of the blood-globules, and diffusion to the colouring matter, or red haemoglobin. I have found this "wrinkle" of great benefit in cleansing white-plumaged birds.] Sometimes, in very old skins, successive applications of water, turpentine, benzoline, and plaster, carefully managed, will work wonders.
I have mentioned the fact that birds may be plunged into turpentine to rid them of insects. After this process they do not readily dry in, proper form, remaining greasy and streaked with, dirt — in fact, in a generally deplorable condition (as I know to my cost, teste, the Leicester Museum collection, ignorantly treated in this manner before my advent). Birds treated with turpentine must be well washed down afterwards with benzoline and then dried in plaster of Paris, as before described. In cleansing old specimens, do not forget to dust them, or to beat them thoroughly with feathers, before applying the benzoline, etc..
In a fresh specimen it would be a person's own fault if he should fail to clean a bird, even were it dipped in blood and grease. Patience and several cleanings are all that are necessary.
Dark plumaged birds — which may have light or white parts — will require care in cleaning, in order that their darker feathers may not be dulled by contact with the white plaster. Should this happen, however, in spite of all pains, it will be found that beating with feathers, and a light touching over with wadding, on which a very little benzoline has been poured, will brighten them up wonderfully. Ostrich and other feathers may be effectually cleaned by any of the foregoing methods, and, by management, re-curled with a blunt knife and the fingers.
"MAKING UP" From Pieces. — I have before mentioned that birds are sometimes made up feather by feather, and also when pulled to pieces for "relaxing." The first is simply pretty pastime, which any person possessed of patience, some little ability, and a stock of feathers, paste, and paper, may indulge in as a recreation.
The latter, however, is a different matter, and is practised in cases where a bird's skin is accidentally torn in several parts, or drops to pieces when "relaxed" through imperfect curing, or by old age. When this happens, the amateur need not feel as if the world would be the next thing to tumble to pieces, but simply get to work thus: Make a body of tow, with neck attached, as described; next, pull the legs off (if they have not previously fallen off), wire them, and attach them firmly to the body by clenching their free ends; bend these legs into the position you wish the specimen ultimately to assume and attach the wires at the feet to a block or perch. A T, formed of two pieces of wood, the bottom end attached to a block, is, perhaps, the best support, as you can get all round to adjust everything, even to the tail.
