Issue 6 and Volume 7.

Electric Motors as Applied to the Propulsion of Street Cars.* The mere question of obtaining motive power from electricity is neither new nor startling; but it is only since the discovery of the means of economically producing powerful currents of electricity, that motion by this method becomes practicable. When currents of electricity were first utilized for practical purposes, and for many years alter, the cost of generating them precluded their application to the production of motion. They were only used for metallurgical purposes and telegraphic signals, but by the discoveries and developments of the past few years the whole aspect has undergone a change. Scarcely fourteen years ago the principle of the dynamo-electric machine was placed at the disposal of the public. This principle immensely diminished the cost of producing current. By this principle the energy of coal could be evolved in the steam engine, thence conveyed to a distance…
