A two-page installment (No. XVII) of a serial on weaving from the journal Engineering, dated 12 February 1875, explaining how the Jacquard apparatus is applied to the loom. It describes a 40-hook example with harness, leashes, comber board and mails, and shows how designs are repeated, reversed or mirrored across the cloth to reduce the number of hooks needed. It covers selvage hooks, a point harness, tie-ups (London and Norwich), harness materials and the use of an eight-leaf satin ground. Figures 144-154 are engraved diagrams of the machine and design grids.
