Mar.eIous Productions in the Maj chinery Department-A Tribune En- zine Developing 5000 horse Power

St. LOUIS, aug. ll.-ln addl. Ion 10 the exposition power plant proper, which will develop 22 900 horse power there will be exhibited in the Depart ment of Machinery at the Worlds Far of 1904 a large number of power generators which will increase the to- tai horse power to about 10000 Thom- as M Moore, chief of the Department of Machinery, has the following to say upon the exhibitors power plant:
 The Department of Machinery of the Worlds Fair at St. Louis has prac- tieally decided to accept an Iowa. built steam engine as one of the prime movers in our great exposition power plant. A few days since con- pleted arrangements with the Murray Iron Works, of Burlington, to accept one of their 800 horse power heavy duty Corliss type steam engines. I expect to directly couple to this a .Crocker-Wheeler generator. and this generating set will be one of five items which will operate our tram rural rail- way system.
 The character and territorial dis tribution of the states from which these items are drawn is interesting One steam engine of 500 horse power is the product of the Harrisburg, Pennsylvania A second steam en- zine of TOO horse power is the pro- duct of the Lane and Bodley Co.,. of Cincinnati, Ohio A third, of 500 horse power, is the product of the Murray Iron works, of Burlington, Iowa. A gas engine of 1,500 horse power is the product of A. Borsig, of Tegal. near Berlin, Germany, and the gas producer for the operation of this engine is the product of Julius Pintsch, of Berlin, Germany. A tangential wa ter wheel of 300 horse power rating is the product of the Abner Doble O.. of San Francisco, California. and the artificial head to operate this water wheel will probably be effected by a centrifugal pump directly driven by a steam turbine from Stockholm. Swe- den. and the water will be measuerd by meter built by the Builders Iron Foundry. Providence, Rhode Island The generations will be the product of the Crocker-Wheeler Co.,. of Ampe- TO. New Jersey, and the switchboard will probably come from Boston. Mas sachusetts. All of these items will be assembled on one large space. where also an opportunity will be given to each of the constituent ex- hibitors to install an office adjacent to their exhibits.
 The total load will be 300 horse power, with a capacity for temporary overload of 25 per cent additional. Save in very minor instance, we do not expect to generate any 500-vot ii- ton for the operation of our ;ntrimural railway which will be about nine miles long-all within the fences of the exposition.
 "The total power used and gener- ated by the exposition will be in the neighborhood of 50.O00 horse power. A relatively small percentage of this as above stated would be 500-volt direct current. A still smaller pre- portion of this will be 2,400-volt. three phase, 50-cycle alternating current, and very minor items will give Us .110 and 22O-volt current. but over S0 per cent of the electric energy which we will avail of will be in 6.600 volt, three-phase, 25-cycle current.
 without at the present burdening you with the details of the various constituent parts of this great power plant, I think it will gratify you to learn that the largest unit will be 5000 horse power steam turbine, and the next largest a 5000 horse power compound horizontal and vertical re- cCprocating steam engine-the last named from Soaring. Belgium.
 We have come 10 talk of thous- ands of horse power SC glibly and easi- ly that I think we hardly appreciate that we have reached the limit of pos sibility with the present carrying cs- pacity of cur railways. By this I mean the capacity and free pas sage room on and through railway bridges and through railway tunnels Neve-- the-lessI I think it is fact that not one person in hundred thousand has ever seen a steam turbine of 5000 horse power capacity; not one person in ten thousand has ever seen a re- ciprocating steam engine of 5000 power capacity, and no one in the world has ever seen a gas engine of | 5000 horse power capacity.
 By comparisons with former ex Dositions. the following facts appear: ! The largest steam engine in the Chi cago Exposition was rated at 250O | horse power, and the largest gas en- | zine in that exposition al 10 h orse power. The largest steam engine in the Paris exposition of 1900 (which, by the way. was the largest steam en- zine ever exhibited in any exposition up to this time) was rated at 1000 horse power. It will thus be seen that we show a steam engine of over three times the power of the largest shown in the Chicago exposition, and over twice rbe powe" of any shown in the Paris exposition; in fact. :n any eyp0sit.cr Drior tO fiji time
