EXPEEIMENT STATION. 99 



FEEDING STUFFS. 



Twenty samples of Feeding Stuffs have been under examina.^ 

 tion during 1882, viz : 



4 of Maize Fodder. 



4 of Maize Ensilage. 



8 of Hay. 



1 of Rice Feed. 



1 of Cotton Seed Meal. 



1 of Corn Meal. 



1 of Wheat Bran. 



Maize Fodder and Ensilage. 



About September 1, 1881, Dr. M. Miles, recently in charge of 

 the Experimental Department of Houghton Fa,rm, sent to the 

 Station samples of Maize Fodder both from "Field Corn" i. e., 

 Maize planted in hills as usual for the crop of grain, and from 

 " Fodder Corn" or Maize sown more thickly in drills, for the crop 

 of stalks and leaves. These samples were selected with especial 

 care, in duplicate, and dispatched at once to the Station in close 

 boxes. At the same time weighed quantities of the same material 

 were put in a silo where they remained until about the middle of 

 January, 1882, when they were taken out and sent to the Station. 



Analyses (more or less complete) of all these samples were 

 made with the prime object of learning something of the kind 

 and degree of chemical change which occurs in the silo. As a 

 control on the results, each of the duplicate samples of the fresh 

 maize stalks were separately examined in order to ascertain what 

 amount of variation in the analyses is attributable to imperfect 

 sampling, it being evidently no easy matter to take from a mass 

 of maize stalks two small portions that exactly correspond in 

 composition to each other or to the mass. The results of the 

 analyses are tabulated on p. 100. 



Comparing the analyses of the duplicate samples of Field Corn 

 CXXV and CXXVI we notice that the water content of the fresh 

 material as received at this Station, differs 0.85 per cent. This 

 difference is no doubt partly due to unavoidable errors in the sub- 

 sampling, drying and weighing, in part also no doubt to original 

 and necessary inequality in the samples. The fat and wax (ether 

 extracts) determined on the dry substance are identical. The 

 albuminoids are reckoned from the amounts of nitrogen found in 

 the dry substance by multiplying them by 6^. Two nitrogen
