semi-cylindrical slab of wood covered with zinc. The skin is first
spread upon this, and the broad, curved beam of the knife glides
across it from end to end, scraping and removing all the loosened
hair, the scarf skin, and the small portion of animal matter adhering
to the skin.

After the unhairing, kid skins must be fermented in a drench of bran,
whose purpose is to completely decompose the remaining albuminous
matter, and also to remove all traces of the lime. The operation is
extremely delicate. While the gelatine is not so sensitive to the
decomposing action of the ferment, nevertheless great care is required
to prevent overfermentation and resulting damage to the texture of the
skin. It is impossible for even the most experienced to tell just how
long the fermentation should continue. Sometimes the work is done in
two or three hours, and sometimes it requires as many days. Incessant
watchfulness both day and night is required to detect the critical
moment. With the less delicate skins this bran bath is not necessary.
Lime and acid solutions accomplish the same purpose. When the gelatine
matter is all removed the skins are ready for the actual curative
process.

Oil dressing or Indian dressing--which merely differ in application,
but are founded upon the same principle--is the most simple method of
curing skins. The principle of each is the soaking of the gelatine
fibers of the skin with oil, the union of the latter and the gelatine
appearing in the form of oxide, and resulting in the insoluble,
undecomposable, pliant, and tough material known to the commercial
world as leather. The first step in the oil dressing, after the skins
have been duly soaked to render them porous and absorptive, is to
cover them with fish oil and place them in the stocks or fulling
