A 1872 article from a US industrial survey tracing the shift from hand spinning and weaving to machine production, with emphasis on cotton and woollen machinery in America. It covers the spindle, distaff and spinning-wheel, Hargreaves, Arkwright and Crompton, English restrictions on exporting machinery, and colonial spinning-schools in Boston. It then profiles Samuel Slater, Alfred Jenks and Barton H. Jenks, and their Bridesburg Manufacturing Company near Philadelphia, describing Jenks's spindle and bobbin improvements.
