The fuel value of corn, T. L. Lyon (Nebraska Sta. Press Bui. ft, 

 pp.2). — "The present abundance of corn and its low price has occa- 

 sioned much speculation as to its luel value." 



In a preliminary test at the University of Nebraska ''a good grade 

 of yellow dent corn on the ear of this year's crop and not thoroughly 

 dried" was compared with screened Rock Springs nut coal for heating 

 a boiler used to supply power at the university. In this test 1 lb. of 

 coal evaporated 1.9 times as much water as 1 lb. ot corn, a result con- 

 firmed by calorimeter tests. 



"The coal used cost at Lincoln $6.65 per ton. With coal selling- at this price, and 

 worth 1.9 times as much lor fuel as an equal weight of corn, the fuel value of the 

 latter would l.e $3.50 per ton or 12.25 eta. per hnshel. 



"The following table shows how much coal is worth per ton when its heating 

 power is the same as that used in the experiment, and when corn is selling at a cer- 

 tain price per bushel : 



Corn per bu. ( !oal per ton 

 9 cents $4. 87 



10 cents 5.41 



11 cents 5. 95 



12 cents 6.49 



13 cents 7. 11 



14 cents 7.57 



15 cents 8.11 



"It will thus be seen that if this quality of coal were selling at less than $6 50, 

 and corn were bringing 12 cts., it would not pay to burn corn, while coal must sell 

 as low as $5.41 per ton to be as cheap fuel as corn at 10 cts. per bushel."
