A 1908 article from Cassier's Magazine reviewing the competing sources of motive power for textile mills, chiefly in Britain. It compares steam engines, steam turbines, gas engines with producer plants, and electric drive by three-phase and direct-current motors, with rope and belt transmission as the alternative. Topics include flexibility, steadiness of running, reliability, power economy, maintenance, and group versus individual driving of spinning frames, mules and looms. Photographs show a Hick Hargreaves cross-compound engine, a rope race, a turbo-generator, motor-driven ring frames, a gas engine and individually driven looms.
