THEED TEST. 
During the fall of 1919 changes were made in the equipment of the 
pumping plant. A -i-cycle. 50-horsepower Ingeeo distillate engine 
was installed to drive one of the pumps, replacing one of the slide- 
valve engines. Bevel gears of cast steel, having a ratio of 213 to 
164. were used between the pump and engine. The smaller gear was 
attached to the engine shaft. Both gears were hand-finished and 
operated with very little noise. 
In the test of unit Xo. 1 of this plant after the above changes the 
oil used by the engine was carefully weighed, while the output of the 
pump was measured by means of a Pitot tube in the discharge pipe. 
The lift was determined from gage readings on the suction and dis- 
charge basins. Kerosene oil was used for fuel. Table 11 gives the 
results of the test.
