The skins of mammals in the flesh may, if bloody, be washed, should the blood be new, or combed with the scratch card (see ante) if it has dried on the hair or fur. In old skins washing is effective when the animal is relaxed. Freshly skinned deer and bulls' heads should always be washed and combed, and wrung out before having the preservative applied.
Mammals' fur is also considerably improved in tone by being well brushed with stiff horse or carriage brushes, and afterwards wiped down with turpentine, followed by benzoline.
When a skin is properly cleaned and finished, it may be lined with red or black cloth, or baize, and a "pounced" border of cloth attached. The tools for "pouncing" are to be bought at most saddlers' or ironmongers'.
I have been asked many times what to do, if camping out abroad, supposing you shot a tiger or a bear, and wished to preserve the skin as a "flat." Simply lay it on the ground and slit the skin underneath, in a straight line through the under lip to the tip of the tail, then make four cross cuts from the median line along the inside of the limbs down to the toes, and skin out the body by stripping it in a careful manner, not allowing any pieces to be cut away, in case you might change your mind and wish it mounted as a specimen.
Take out the skull, clean and preserve it, and though skinning out the toes completely, be careful to retain the claws in their seats. When the body is removed, "flesh" the skin, which means scraping and cutting away all superfluous flesh and fat, then lay it out flat and rub it well in with the burnt alum and saltpetre (Formula No. 9). In dressing thick skins, it will be advisable to make a paste of the alum and saltpetre by mixing it with a little water, and repeatedly rub this mixture into those parts where the skin is thickest, such as around the lips, eyes, ears, etc.., taking care that not a wrinkle in any part escapes a thorough dressing, otherwise it will assuredly "sweat," and the hair come off in such places.
The skin may now be rolled or folded together for travelling, but the next day, when settled in camp, it must be dressed again — twice will be quite sufficient for any but the thickest or most greasy skins; after that it must be exposed day by day to the sun and air, taking care meanwhile to guard it against all possible enemies. Treated in this manner, it has no "nature" in it, but is "as stiff as a board;" before this happens, however, it will be advisable to roll it, unless you have plenty of space at disposal on the floor of a travelling waggon, etc.., in which case it may be folded to fit. A folded skin is, however, worse to treat, subsequently, than a rolled one.
Valuable skins should be, when practicable, sprinkled with insect powder, turpentine, or pepper, and sewn up in sacking until they can be tanned, or made into soft leather, by any one of the processes previously described. If time is no object the skin may, after the first rubbing-in of the preservative, be stretched by the old-fashioned method of "pegging out," or by the more efficient professional "frame," made of four bars of wood, to which the specimen is "laced," or sometimes made of bars of wood and stout sacking, adjustable by means of wood screws, which open the bars and stretch the attached skin in a proper manner to the required size.
When alum, etc.., cannot be obtained, recourse must be had to common salt, which is generally procurable in any part of the world; a strong — almost a saturated — solution with water must be made of this in a tub, and the skin placed in it. If possible, change the liquor after a few days and add fresh; head the tub up tightly and the skin will keep many years. I received the skin of a polar bear, sent from the Arctic Regions to Leicester for the Town Museum, simply flayed and pickled in this manner, and after a lapse of two years it was examined, and found to be perfectly sweet and firm — quite fit for mounting when opportunity served.
Of course, these salted subjects are terrible nuisances either to mount or to treat as flat skins, having to go through many processes to rid them of the salt which pervades them. The first process is thorough washing and steeping in water, constantly changed; after that experience alone determines the treatment to be pursued. If alum were mixed with rough salt in the proportion of two parts of the former to one of the latter, the solution would become more astringent in its operation. A pickle made of oatmeal, saltpetre, and boiling vinegar has been recommended, but I have not yet tried it.
I think I have now put the would-be tanner and currier in a fair way to do some of the dirtiest work imaginable, and if after a fair trial he does not cry, "Hold, enough!" and hand all future leather-dressing over to the professionals, I shall indeed think him "hard to kill."
