A single-page installment from Leon Faux's series on French worsted spinning, describing two types of gill-box used to prepare wool for drawing. It covers the S.A.C.M. intersecting gills, with their upper and lower sets of fallers, and the O.P.S. step gill-box, including faller counts, pin arrangement, drawing point, and sliver delivery. Two line diagrams (Figs. 113 and 114) illustrate the machinery.
