CARPENTER, a worker in wood. Carpenters are commonly classified according to the work which they do, e.g., ships' carpen ters, rough carpenters (rough carpentry, an obsolescent phrase, meaning the erection of the framework of a wooden house), cabi net makers, etc. Wood-cutting machinists are more properly classed as mill-sawyers. In the 18th century carpenters, being still chiefly master carpenters or journeymen, worked by the piece, but with the growth of general building firms master car penter piecework practically ceased. Carpenters are very strongly organized both in the United States, in the United Brotherhood of Carpenters, and in Great Britain, in the Amalgamated Society of Woodworkers, which has also powerful branches in the dominions, where the older name of Amalgamated Society of Carpenters and Joiners (A.S.C.J.) is often retained.
