A 1899 article from Cassier's Magazine by Stephen Greene on how the source of motive power shaped the design and siting of cotton mills. It divides mill history into three periods: water power up to about 1860, steam engines (Corliss cut-off) from 1860 to about 1893, and the beginning of electric transmission. It discusses wooden breast and overshot wheels, turbines, engine placement, and shafting. It closes with the Pelzer Manufacturing Company mill in South Carolina, which was driven by electric power from a site 2.5 miles away.
