320 EXPERIMENT STATION RECORD. 



has become available, since "by locating the power plaut above the 

 head of the irrigation system the water can be made to turn the elec- 

 tric generator and then continue along its course undiminished and do 

 service for the farmer as before, while the energy obtained from it may 

 be transmitted to the valley, or even to the more remote centers of 

 industry, and there serve its purposes." The general features of a plant 

 for this purpose were described and detailed accounts given of several 

 plants which are already in operation in the State. 



A committee of 3 to determine and propose means that will promote 

 greater interest in the section on mechanic arts was appointed, as 

 follows: A. J. Wiechardt, C. E. Richards, and W. 8. Aldrich. 



(J. R. Richards, of Nebraska, submitted a paper on the "Calorimctric 

 determination of the heating value of corn." This paper gave results 

 of comparative tests of the fuel value of corn and coal when burned 

 under boilers and in a fuel calorimeter. From the results thus obtained 

 a table was constructed showing what must be the relative price of 

 corn and coal in order that the former may be economically used for 

 fuel.' 



1 A preliminary report on these investigations is given in E. S. R., 9, p. 196.
