Bulletin 183. Mechanical Tests of Pumping Plants Used for 

 Rice Irrigation in Louisiana and Texas, 1905 and 1906. This 

 bulletin gives the details of a large number of mechanial tests 

 of pumping plants used for rice irrigation in Louisiana and Texas. 

 Most of these plants use crude oil for fuel, and they are therefore 

 of special interest to those using this fuel. It also includes esti- 

 m.ates of the cost of different types of plants and their cost of 

 operation, showing that in most instances the high-class machin- 

 ery is very little, if any, more expensive in first cost and very 

 much cheaper in operation. 



Application for this bulletin should be made to the Director of 

 the Office of Experiment Stations, W'ashington, D. C.
