A two-page dictionary entry on flax from Knight's American Mechanical Dictionary. It covers the earliest historical mentions of flax, the Egyptian processing scenes at Beni Hassan (retting, braking, beating, hackling), and Pliny's account of the process. It then outlines nineteenth-century mechanical preparation (braking, scutching, hackling, carding, roving, spinning) as in a Leeds mill, and a Swedish method of treating flax with sea-water, birch-ashes and quicklime.
