The costlycable is destined tofollow the horseinto obscurity. The locomotivereplaced animalpower for long dis-tance transporta-tion, but there aremany objections toit for hauling smallcars at frequent in-tervals through thestreets of town sandcities. For this service animal power continued inuse until the cable and the electric current enabledus to harness the car to a stationary engine or aturbine. The electric car has replaced the horsecar and has also revolutionized street railwayservice. By it speed and comfort have beenincreased and operating expenses reduced. The Problem Presented.—Whether the electricmotor is to continue its widening range and take. 1500 Kilowatt Generator, driven by a verticalengine. Metropolitau West Side Railway, Chi-cago. ELECTRICITY AS A MOTIVE POWER. 395 the place of the steam locomotive is a very inter-esting and important question. While the loco-motive is not adapted to the conditions of streetrailway traffic, it is possible that long distancetransportation cannot be met as economicallyby the motor as by the locomotive. It is often asserted, and possibly truly, thatelectricity is in its infancy and that it onlyawaits further comprehension of its mysteriesto enable it to be applied to the solution ofevery kind of problem. A little further develop-ment, many believe, will relegate the steam loco-motive to the past and add unprecedentedly tothe speed of trains. Some even predict thatthe motor w^ill completely supplant all steamengines. Intelligent consideration of the subject requiresan examination of the functions of electricalaction, the characteristics of electrical apparatusand th
