At the engine there are cut-offvalves between the distributing steam and exhaust mainand each engine, so that any particular engine may becut off entirely from its steam or connections incase of any exigency that may require it. The entirepiping is planned on a basis of 150 pounds steampressure. THE EN(iINliS are Westinghouse compound, non-condensing, ten in num-ber, and arranged in two batteries of five each, with arated horse-power of 250 and a maximum of 300 cylinders are 16 inches by 16 inches stroke, and 16inches by 29 respectively. The crank shaft is 7 inches indiameter, and 11 feet long. The dvnamos are belted. The boilers are rated at 2 87 horse-power each, and thefeed water is heated to 212 degrees by Wainwright Cor-rugated Tube Feed water heaters, made by the Wain-wright Manufacturing Company, of Boston. No purifieris expected to be necessary. The piping is a feature worthy of more remark thanour space allows. It is probably- the largest line in theWest. The steam pipes are 18 inches in diameter, andthe exhaust pipes 22 inches. Each main is independent,and can be cut off entirely at will. The header is 28inches in diameter, and 43 feet in length. The boilerspipe to this. An independent 18-inch line for each fiveengines is run from this header to the engine distributingmain. Each main has a cut-oft valve in the boiler-roomso that either entire line from the cut-off valve to the direct, and the belt wheel is 84 inches in diameter with a25-inch face. THE ELECTRICAL SUPPLY.
