FIRELESS LOCOMOTIVE.

The Chicago Tribune gives the following account uf the “ tirale.-ts locomotive” in' use on the tramway of that city ! —“ la front of thu cure was the motive power. contained in a small, compact, and neat locomotive, manipulated by an engineer. Thin was the tireless locomotive. It-consists of a boiler, eight feet long and three feet in diameter, with the usual machinery on a small scale. There was no fuel, no fire, no fireman. The steam was supplied for the round trip of six miles before starting. At was a supply boiler, sixteen feet by three feet, in which steam was generated until two hundred pounds pressure was indicated by the steam gauge. The locomotive boiler was three-fourths full of cold water. Instead of boiling (his by means of a fire, and raising the pressure to a required height,' steam wail introduced from the supply boiler through an iron tube, (The iron tube, was connected with the locomotive boiler, the latter running under,the water along the Bottom of the boiler, and letting out the steam as it was freed (from the supply (boiler into the locomotive boiler. This stesrajrisinglthroijgh'tho cold water , permeated it, and quickly raised its pressure to one hundred and seventy pounds. "With this supply of steam tliej locomotive Started, drawing a heavy four-horse car over jthree miles to Thirty-fifth street in ten minutes.- The amount of steam Consumed representing eighty pounds pressure, the locomotive starting, baok-wilh ninety pounds k remainiug.
