[Fig. LXXIII.] illustrates a thread forming part of a lower shed. In the drawing the mail is raised, but at the same time the heddle of harness is lowered, compelling the thread to rest on the bottom of the lay. This figure is designed to show warp-thread passing through mail No. 6, of leash a´, and harness No. 6, in [Fig. LXIX.]
[Fig. LXXIV.] is a side view of a thread forming the upper part of a shed where mail and harness have been raised the same as in [Fig. LXIX.], the warp-thread passing through mail No. 11 of leash, a´´, and harness No. 3.
[Fig. LXXV.] illustrates mail not raised and harness down. This change is not necessary in Fig. IV.; the warp-thread forming the lower part of the shed.
