cost of the daily diet as compared with that of the precediug year. 

 The daily grain feed rations, which contain gluten meal as an ingre- 

 dient (II, V, VI, IX) are 3.32 cts. higher than they would have 

 been during the preceding year, for the corresponding months ; those 

 which contain cotton seed meal (I, IV, VII, VIII) are 2.85 cts. 

 higher, and those which contain old process linseed meal (III) are 

 2.40 cts. higher. This increase in cost is largely due to the excep- 

 tional high price of corn meal and wheat bran. 



The substitution of gluten meal or of cotton seed meal, by old 

 process linseed meal, three pounds in each case, causes a reduction of 

 but 0.3 cts. in the market cost of the grain feed portion of the daily 

 diet per head. The market cost of the daily grain feed rations used 

 per head during the entire experiment varies only from 11.85 cts. to 

 12.15 cts. a di-fference of 0.3 cts. Allowing, however, a proper 

 recognition of the commercial value of the essential manurial sub- 

 stances, nitrogen, phosphoric acid and potassium oxide contained in 

 each of the grain feed constituents of the daily fodder rations, we 

 Jirtd in our case, that the net cost of the cotton seed meal containing 

 daily grain feed rations (I) amounts to 7.01 cts. ; while that of the old 

 process linseed meal containing daily grain rations (II) is 7.29 cts. 

 and that of gluten meal containing fine feed rations {III) is 8.01 cts. ; 

 a difference respectively of 0.22 cts. to 0.94 cts. per head. This 

 difference in net cost is due to the higher manurial value of cotton 

 seed meal and of the old process linseed meal as compared with 

 gluten meal at stated market prices. 



The choice of different coarse fodder articles in the daily diet 

 exerts a much greater influence on the market cost of the latter, than 

 that of the different kinds of grain feed. The market cost of the 

 coarse fodder portion of the daily diet, averages 13.5 cts. in case rowen 

 alone (18 pounds) serve as coarse feed; it averages 11.5 cts. in case 

 forty-four pounds of mixed ensilage and five pounds of rowen are 

 daily fed ; and it amounts to from 4 to 4.5 cts. in case from sixteen 

 to eighteen pounds of corn stover are used per day for that purpose. 

 These facts find their expression in the above stated market cost 

 of the nine complete daily fodder rations used during the trial. The 

 market cost of the complete daily fodder ration, I, II, III, VIII, IX, 

 containing rowen, averages 25.55 cts. ; rations IV, V, containing 

 mixed ensilage with rowen, averages 23.63 cts. ; and ration VI, VII, 

 containing corn stover as coarse feed, averages 15.64 cts. The 

 difference in the marlcet cost of the above described nine daily fodder 

 rations caused by the use of different coarse fodder constituents, rises
