The Book of Household Management by Mrs. Beeton

offal of most domestic animals, the pig is not behind the other mammalia in its usefulness to man. Its skin, especially that of the boar, from its extreme closeness of texture, when tanned, is employed for the seats of saddles, to cover powder, shot, and drinking-flasks; and the hair, according to its colour, flexibility, and stubbornness, is manufactured into tooth, nail, and hairbrushes,--others into hat, clothes, and shoe-brushes; while the longer and finer qualities are made into long and short brooms and painters' brushes; and a still more rigid description, under the name of "bristles," are used by the shoemaker as needles for the passage of his wax-end. Besides so many benefits and useful services conferred on man by this valuable animal, his fat, in a commercial sense, is quite as important as his flesh, and brings a price equal to the best joints in the carcase. This fat is rendered, or melted out of the caul, or membrane in which it is contained, by boiling water, and, while liquid, run into prepared bladders, when, under the name of _lard_, it becomes an article of extensive trade and value.
