An illustrated 1843 Penny Magazine supplement describing a visit to the Old Silk-Mill at Derby, built by John Lombe around 1717. It outlines the origin of silk from the silkworm and cocoon, then the history of silk-throwing in Italy and England, including Lombe's industrial espionage and William Hutton's boyhood work there. It goes on to describe the mill's processes: winding, cleaning, doubling, spinning and throwing (singles, tram, organzine), and scouring before dyeing. Engravings show the machines and workers, including a brass-tag machine for silk boot-laces.
