Suynmary of Coefficients, Cocoa Shells, Series XVII., Period IX. 



The coefficients for both sheep agree closely except for pro- 

 tein. In both cases, however, the protein coefficient is ex- 

 tremely low, due, perhaps, to the presence of considerable 

 vegetable alkaloid. It is doubtful if they have more than one- 

 half the value of corn meal. Their use will be more fully dis- 

 cussed elsewhere. 



Brook Farm Hay. 

 This hay was purchased at the Brook Farm, just north of 

 the station grounds, and consisted of a mixture of timothy, 

 red top and clover in good condition. Sheep I. and 11. left a 

 considerable portion, Sheep I. refusing the finer portion and 

 Sheep II. the coarser part. In a later trial Sheep V. was in- 

 duced to eat the entire ration. It was used in connection with 

 a feeding experiment.
