A 1879 monograph by John L. Hayes, secretary of the National Association of Wool Manufacturers, republished from the association's Bulletin. It traces the history of textile machinery in the United States, from English export restrictions and Samuel Slater's Pawtucket mill through Waltham, Lowell and the independent machine shops. It then describes American contributions to cotton and woollen machinery (ring spinning, looms, carpet looms, felting, calico printing). It also covers links to machine tools, locomotives, firearms and agricultural machinery, and closes with an argument for keeping the tariff on imported textile machinery.
