A two-page set of dictionary entries on flax processing from Knight's American Mechanical Dictionary. It defines tools and operations such as the hackle (heckle), hatchel, grassing, retting, scutching and watering. It also covers machines including the flax-cutting machine, heckling machine, spreader and spreading-frame, and gives the table of linen yarn measures (lea, hank, bundle). One engraving shows an early heckling machine.
