It is not believedthat the increased diameter of the res-ervoirs will materially effect precipita-tion. Figs. 6 and 7 are drawings of amethod of piping and location of reser-voirs which has given most excellentresults in heavy freight and coal service,where from 50 to 75 cars are handledon one train. About 28 ft. of lYz is used between the pump and firstreservoir, and, as will be noted, is freefrom sharp bends and right angle fit-tings. The discharge pipe connection atthe first reservoir has a nipple on theinside of the drum pointing downward,so as to turn the current away from theconnection leading to the second reser-. FIG. 5. PLAN VIEW OF RESERVOIRS The same system of reservoirs andpiping is employed on heavy passengerengines operating in high speed trainservice between Jersey City and Phila-delphia, handling from three to twelvecar trains, where climatic conditions arequite different from that in mountainservice. The passenger engines wereformerly equipped with one large reser-voir located at the back of the tender,with about 35 ft. of pipe Tjetween the ON TOP OF BOILER, WIDE FIRE BOX. voir. About 7 ft of I/i in. pipe is usedbetween the two air drums. The brakevalve connection is made in a mannerthat prevents moisture being drawn fromthe reservoir by the current of air pass-ing through the reservoir. This methodof piping is not considered preferableto that shown in Figs. 3, 4 and 5, butwas resorted to as the most economicalsubstitute for a system that formerlygave a great deal of trouble. It will
