HATCH EXPERIMENT STATION. 



[Jan. 



cows, there was a slight diiference in case of the average 

 consumed by the two herds. 



The spring wheat bran and cotton-seed meal were of good 

 average quality. The oats were of standard quality, pur- 

 chased Avholc and ground by the local miller. The Chicago 

 gluten meal contained 40 per cent, of protein and 3.91 per 

 cent, of fat in dry matter, thus furnishing a high percentage 

 of corn gluten and a minimum percentage of corn oil. The 

 corn was grown upon the station grounds, likewise the hay 

 and rowen. The first cut hay was largely timothy, with a 

 small admixture of red-top and clover. It contained 8.24 

 per cent, of protein in dry matter, and the rowen 14.20 per 

 cent. The corn oil, procured of the Glucose Sugar Refining 

 Company of Chicago, had a golden-yellow color, was clear, 

 and had a marked odor of Indian corn. It was regarded as 

 a very satisfactory sample.
