The engines are provided with a by-pass so that livesteam at boiler pressure may be fed to the receiver to facili-tate starting when the high pressure is on dead center. Thereceivers between the high and low-pressure cylinders aredrained by Plynn traps. All engine valves are packed withCook metallic packing and the low-pressure exhaust valvesand all piston rods have double steam-sealed metallic pack-ing, the steam being fed from the receiver to the space be-.

Each engine unit has a jet condenser of Dean manufac-ture, with its auxiliaries located in the basement betweenthe foundations for the high and low-pressure cylinders. Twofree-exhaust pipes standing on footings near the stack areprovided. Each of the condenser sets has a capacity for 20,000 pounds of exhaust steam per hour with water at 70degrees F. The condensing water is taken direct from a30-inch suction main connected with the supply well, as pre-viously described. The discharge is led through two 12-inchpipes into a 16-inch pipe which connects with the 36-inchdischarge conduit leading to the lake nearby. The con-densers are provided with a forced injection from the low-service pump, for starting. The condenser air pumps can
