TESTS OF THE FERRE, HINE'S, AND RICHARD RELIFT PUMPING PLANTS OF THE LOUIS- 

 IANA IRRIGATION & MILL CO., CROWLEY, LA. 



During the summer of 1919 the Louisiana Irrigation & Mill Co. 

 installed several pumping units in relift plants. Tests were made to 

 determine the performance of these pumping units, with results as 

 shown in Tables 29, 30, and 31. The equipment in each plant 

 consisted of duplicate units made up of 60-horsepower internal- 

 combustion engines direct-connected to 24-inch centrifugal pumps.
