There was a building in which the bristles were cleaned and dried, for the making of hair cushions and such things; there was a building where the skins were dried and tanned, there was another where heads and feet were made into glue, and another where bones were made into fertilizer. No tiniest particle of organic matter was wasted in Durham’s. Out of the horns of the cattle they made combs, buttons, hairpins, and imitation ivory; out of the shin bones and other big bones they cut knife and toothbrush handles, and mouthpieces for pipes; out of the hoofs they cut hairpins and buttons, before they made the rest into glue. From such things as feet, knuckles, hide clippings, and sinews came such strange and unlikely products as gelatin, isinglass, and phosphorus, boneblack, shoe-blacking, and bone-oil. They had curled-hair works for the cattle tails, and a “woolpullery” for the sheep skins; they made pepsin from the stomachs of the pigs, and albumen from the blood, and violin strings from the ill-smelling entrails. When there was nothing else to be done with a thing, they first put it into a tank and got out of it all the tallow and grease, and then they made it into fertilizer.
