Show OLD~PAPERMAKIN 4 chain wires had been laced or sewed directly to th wooden ribs of the moulds, which caused the pul to lie heavier along each side of every chain.lin in the sheets of paper made thereon. (These rib and the wires in progress of construction may b seen in the illustration of moulds taken from French print of 1698.) The heaviness is noticeabl when paper is held to the light,and from this sligh mark of distinction it is possible to tell what pape was fabricated before the middle of the eighteent century. Paper with this characteristic is terme "antique-laid," and specimens may be examine in the papers marked A, B, and C, appended to thi volume. In Figure 1 d, a portion of a sheet of thi style of paper is pictured, also the wires of a moul on which this kind of paper was made. The absence of backing wires will be noticed in the drawing depicting a section of one of the ribsused in a antique-laid mould It is thought that John Baskerville invented th means of eliminating the dark streaks in the pape by holding the Jaid covering away from the rib of the moulds by the use of wires running paralle with, and under, the laid wires. This prevente the pulp from settling at either side of the chainlines, which was caused by a peculiar suction o the wedge-shaped ribs as the moulds were draw from the vat The effect on the paper of these under wires i Diital image© 2004 Marriot Libary, University of Utah.
