Show GREAT TUNNELING MACHINE. Splendid Photographs Received of the Huge Railroad Tunnel Eater. The Utah Karns Tunneling Machino companj' has on exhibition at its office, photographs of tho large railroad tunneling tun-neling machino which is now under construction at Cleveland, O. The artistic work of tho photographs is of tho highest class, and gives an exact reproduction of tho machine from several sev-eral different views, being the best illustration of this wonderful machine that has yet been prcsonted. These photographs give much valuable information in-formation ns to the construction and practical possibilities of tho machine and can be readih' understood by any mechanical engineer. ' This huge piece of machinery, with tho driving device, weighs, complete, 110 tons, having upon the face" of the wheel 4000 drill points and will bo operated by 14,000 cubic feot of free air per minute, requiring boilers sufficient suffi-cient to generato 1200-horsc power. The machine takos an eight-inch stroke and 150 per minute, with a force of 63.000 pounds. The model of this machine was critically inspected at Cleveland, last month, by prominent mechanical engineers and mining experts, representing repre-senting largo railroad and mining interests, inter-ests, and 60 sanguine were they of its ultimate success that several of thorn predicted that a machine or this weight v.'ould travel ten feet an hour through hard rock. Tf. was conceded that such a machine would revolutionize present methods of railroad tunneling and would almost insure air line work in future fu-ture railroad construction. The Utah company is making every effort to put those machines into practical prac-tical operation in the State, for railroad, rail-road, irrigation and mining tmrposes nnd with tho vast amount of tunnel work now; in sight, the future revenues 01 the company would to bo practically guaranteed. Some of the most conservative business men in the city and State are already financially interested in the enterprise, with the belief that it is one of the best and most far-reaching industrial enterprises lor the quick develop-has develop-has over been brought to Utah. They predict that by the use of this now invention in-vention the wonderful progress in the -v..v yimicui ux. mines will add ma-i?i ma-i?i a? t0 t1he- general prosperity of the State nnd give an impetus to every on Inf dlS-ry. m thfl 'ntor-mountiin country.
