Cork.

Dealers divide cork into four classes, according to thickness, viz.: Thick corks, having more than thirty-one millimeters diameter; ordinary or commercial, from twenty-five to forty; bastard, from twenty-three to twentyfive ; and thin corks, less than twentythree millimeters. A cork of .good quality should be white, tawny or f|bk, with a close, fine grain, and free from cracks. The powder of cork is met with in trade under the name of liegine. The waste resulting from the manufacture of bottle corks is made useful by being mixed with plaster, etc., for partitions, filling walls, and other purposes; it also produces an excellent kind of charcoal, which is said to be good for gunpowder manufacture. Linoleum is a composition of cork powder and linseed oil. In some instances cork powder is found highly adulterated, sawdust and clay being employed for this purpose. Cork leather is made from India rubber and cork powder, and has come into considerable use for waterproof purposes.
