A February 1895 Cassier's Magazine article describing the Columbia Cotton Company mill at Columbia, South Carolina, the first cotton mill powered entirely by electric motors. It covers the water-powered generating station on the Congaree River, two 500-kilowatt three-phase generators, the underground cable line to the mill, and twenty 65-horsepower three-phase induction motors suspended from ceilings. It gives engineering details on speed regulation, efficiency (about 82 percent) and operating results, with photographs, plans and cross sections.
