—These are chiefly sold for glue stock. In removing sinews from the legs, care must be used not to cut too deep in the heel of the foot, it being preferred to leave some glue stock on the foot rather than to cut too deep and remove the fat which goes to make up the neatsfoot oil which is much more valuable than the glue stock. This part of the product, well drained, should be taken to a cool, although not necessarily refrigerated room, and thoroughly salted; It is often found necessary to overhaul it and resalt it in order to keep it from “sweating.” After it has been cured ten days or two weeks it is ready for the glue department.

Blades and Ribs.

—Where cutting and shipping cattle is done in profusion there are many small bones resulting. If hard bone is being made these bones are cooked in open vat from six to eight hours. Cellular bones are usually cracked so as to make for free extraction of oil.
