SUMMARY. 



The foregoing data indicate that gluten meal is fully equal to 

 cotton-seed meal when fed in sufficient quantity to make the 

 amount of digestible nutrients equal in each ration. 



It is not equal to cotton-seed meal pound for pound as a 

 source of protein, as it contains, on an average, about one 

 quarter less of that nutrient. 



It makes a very good quality of butter, but slightly softer 

 than that made from cotton seed meal ration when fed in the 

 quantity used in this experiment. 



SILAGE COMPARED WITH GRAIN AS FOOD FOR MILCH COWS. 



The object of this experiment was to again test the practica- 

 bility of substituting silage, made according to Professor 

 Robertson's formula, for a portion of the grain ration. The 

 mixture was made as follows: One acre of matured field corn, 

 one-half acre of horse beans, and one-quarter acre of sunflower 

 heads, cut close, were run through the silage cutter and put in 

 the silo. Owing to an unavoidable delay the corn was 

 allowed to stand until too ripe and dry to make the best quality 

 of silage.
