TEST OF JAMISON RELIFT PLANT OF THE LOUISIANA IRRIGATION & MILL CO., 
CROWLEY, LA. 
This pumping plant contains two units, each consisting of a 
60-horsepower Muncie engine direct-connected to a 36-inch cen- 
trifugal pump. The pumps are primed by small vacuum pump run 
from the engines. A small compressor and a gasoline engine are 
used to fill the air tanks for starting the engines. Although used 
for irrigation, this pumping plant does not differ in any way from 
plants used for drainage. 
Tests were run on both units of the plant. The results are given 
in Table 28. The quantity of water pumped was measured by a 
current meter in a carefully constructed flume in the suction canal. 
The lift was determined by means of gages set in suction and dis- 
charge canals. Fuel oil was accurately weighed by a spring balance.
