This wool fat or lanoline is used in making soap and ointments. The wool is next " carded/' the fibers being interwoven by the fine teeth of the carding machine or " combed," the fibers here being pulled out parallel to each other. Carded wool becomes woolen goods; combed wool, worsted goods. The wastes are also utilized, being mixed with " shoddy " (wool from cloth cuttings or rags) to make woolen goods of a cheap grade. Goat hair, especially that of the Angora and the Cashmere goat, has much use in the cloth- ing industries. Camel's hair and alpaca are also used.

The fur seal fisheries alone amount to many millions of dollars annu- ally. Otters, skunks, sables, weasels, foxes, and minks are of considerable importance as fur producers. Even cats are now used for fur, usually masquerading under some other name.
