~ REPORT OF THE CHEMIST-* 
The work of this department has been almost entirely devoted 
to investigations with fodders and to feeding experiments, includ- 
ing the determination of the digestibility of certain feeding stuffs. 
The questions discussed in this report are: 
1. Composition of feeding stuffs. , 
2. Nitrogen-free extract of foods, its composition and digesti- 
‘bility. 
3. A study of the maize plant, with special reference to the 
chemistry of its growth. 
4, Cattle foods and feeding rations. 
5. The feeding experiment with dairy animals. 
During the winter of 1888-9 experiments were conducted with 
four young animals and two cows. 
1. Feeding experiments: ; 
a. Two animals receiving nitrogenous rations. 
E b. Two animals receiving carbonaceous rations. 
2. Digestion experiments : 
a. Digestibility of nitrogenous ration. 
b. Digestibility of carbonaceous ration. 
c. Digestibility of hay used in above rations. 
d. Influence of roots in above ration. 
e. Digestibility of a milk ration. 
f. Digestibility of alfalfa hay. 
3. Relative feeding value of some grain rations. 
4, Notas from the dairy.. | 
Besides the above there is now in progress a large amount of 
work with ensilage, with special reference to the changes which 
_ take place in the silo resulting in loss of dry matter. The results 
of this experiment and the digestibility of maize fodder, as com-
