FROM PAPER-MILL TO PRESSROOM [Illustration: ANCIENT PAPER-MAKING _The tools of the primitive paper-maker consisted of a pulp vat for the fiber-laden water, a frame, or mold across which was stretched a mesh of closely-spaced wires, and a removable frame known as the deckle; hence the term “deckle edged.” The beating was done by iron shod hammers which were raised and released by cams on a shaft turned by water power: this machine called a stamper is shown in the foreground of this picture._] FROM PAPER-MILL TO PRESSROOM _By_ WILLIAM BOND WHEELWRIGHT _Author of “How Paper is Made,” etc._ The Collegiate Press GEORGE BANTA PUBLISHING COMPANY MENASHA, WISCONSIN 1920 COPYRIGHTED 1920 BY WILLIAM BOND WHEELWRIGHT PRINTED AND BOUND BY GEORGE BANTA PUBLISHING CO.
