AGIUCULTUKAL EXPERIMENT STATION. 29 



DIGESTION EXPERIMENTS. 



The digestion experiments, the results of which are given in the 

 following pages, were not wholly accomplished within the year 

 1891, but were in part performed during the latter part of 1890. 



The materials which were made the subject of these experiments 

 were produced on the College Farm in the summer of 1890, 

 excepting, of course, the bran and gluten meal. The mere deter- 

 mination of digestion coefficients was not, in every case, the mtiin 

 object of the work. While a knowledge of the digestibility of 

 these foods is of value in itself, here it was in large part essential 

 to correct conclusions in regard to quite different questions. 



Experimental Foods. 



The foods whose digestibility was determined were the fol- 

 lowing : 



CXXI. Hungarian Grass. 



CXXVTII. Hungarian Hay (cxxi dried). 



CXXVII. So. Corn Fodder. 



CXXV. Field Corn Fodder. 



CXXVI. Sweet Cora Fodder. 



CXL. Timothy Hay. 



CXLI. 



CXXX1II. Sugar Beets. 



CXXXII. Mangolds. 



CXXX. Rutabagas- 



CXXXr. English Flat Turnips. 



CXXXIV. Gluten Meal. 



CXXXV. Wheat Bran. 



The gluten meal and wheat bran were purchased in the Bangor 

 market and the other foods were produced by the Station.
