71 THE PRINTER. In this business there aj'e two kinds of workmen employed. Compositors, who range and dispose the letters into words, lines, pages, &c. according to the copy before them in certain portions, the manuscript being on those occasions divided for the sake of expedition; and the pressmen, who ap- ply ink to the same, and take off the im- pression. The letters, or types, are made of mixed metals, and are disposed in cases with separate divisions, called boxes. When the compositor fills his composing stick, he empties it into a frame of wood, called the galley; when a page is formed, itistied up; and when all the pages are ranged in order, they are fastened together in a frame, called a chase, with wedges of wood; this is called imposing. There are two forms required for every sheet. As mistakes will occur, a sheet called a proof, is printed off and given to the corrector of the press; who examines it, while a boy reads the copy to him. It order to make these corrections, the com- positor unlocks the form, by loosening the wedges or quoins; and w hen corrected, the form is again fastened, and a revise sent to the corrector. The pressman is assisted by another to ink the form.
