This system docs not have to be startedlifteen minutes before the engine delivers oil, in proportion to the steamconsumption, the instant the engine start-atid when it is running. There is nothingto tiirn on or off before starling or afterstopping or before or after filling, sum-mer or winter. There is no feed regulalion and nothing lo adjust. The lubri- cator is not in some choice position inthe already crowded cab, where the great-est fall can be had. Nor need it beequipped with a special light for con-venience of examination. Oil is injectedinto tlic sieam pipe, sufficiently in the rear.

There is no such thing as wash- ing the valves, with force feed lubrica-tion, because every stroke is made withoil-impregnated steam. These lubricatorpumps will deliver oil against 5,000 lbspressure. No sag in the oil pipes, how-ever great, interferes with the regulardelivery of oil. There is no case of in-jecting a lot of oil the instant the steamis shut off. After testing out one of these lubri-cators a prnminent railroad specilied iten 12 new super-heated passenger engineswith 25x28 in. cylinders and 75 in. drivingwlieels. These engines were put in scrv-iio in Septeinber and October, 1917. Engine No. 1619 on this road, which wasI he first one to
