A short magazine article from 1902 explaining how most manufactured wool cloth contains reclaimed fiber called shoddy, made by shredding old rags in a machine called the "devil" and respinning them with new yarn. It traces the development of the industry from mid-nineteenth-century Yorkshire, notes Dewsbury as the center of the rag trade, and mentions byproducts such as oil, prussiate of potash, flock, and the higher-grade "mungo."
