A special Y-fitting for use in washing out locomotive boilershas resulted in considerable saving in the cost of boiler wash-ing at this point. The roundhouse is equipped with the hotwater washing and filling system, and the special brass fittingis attached to the washout line near the engine, thus providingtwo lines of washout hose, one of which is fitted with a 1 in,cut-off cock at the nozzle. When washing out a boiler the plugs are removed from thefour firebox corners and one line of hose is placed in the front. Arrangement of Y-Fitting for Washing Out Boilers, water leg, the other being placed through the front flue sheetwashout hole. While this is in operation two boiler washersremove all plugs above the running board and the hose fittedwith the cut-off cock is then used along the top of the boiler,beginning at the front flue sheet. By the use of this device ithas been possible to dispense with the services of one man for-merly required at the globe valve in the washout line. Tksting Piston Rods,—An electro-steel company has an-nounced the results of a series of tests on piston rods madeof the steel it manufactures. The steel showed a tensile strengthof 123,775 lb. per sq. in., and an elastic limit of 82,600 lb., withan elongation of 24 per cent in 2 in. and a reduction of areaof 53 per cent. In a revolution testing machine 984,933 revo-lutions were required to break the test piece at a stress of30,000 lb. per sq. in. This steel, which contains manganese, isproduced in an electric furnace
