To test the comparative feeding value of tliis hay two cows as 

 evenly mated as possible were selected, each being cross-bred, seven- 

 eighths Jerse}- and one-eighth Ayrshire. The}- were comparatively 

 fresh, having been in milk but a few weeks. The}- each received 

 three lbs. of corn meal, three lbs. of cotton-seed meal, one and one- 

 half lbs. of bran, and twenty- lbs. of ha}- daily throughout the entire 

 period of feeding. 



Bess was fed during the first period of tw^elve days upon late hay, 

 the first six being in preparation and to overcome the influence of 

 previous feeding, and the milk product of the last six days of the 

 period was taken as the result of the late hay. At the close of the 

 first period her feed was changed to early hay, and she was fed 

 upon this during the second period of tw-elve days, the first six to 

 destroy the influence of previous feeding as before, and the last six 

 the milk produced represented the result of the early hay consumed 

 during that time. The third period her hay was the late cut, fed as in 

 in the first. This feeding alternately on late and early hay was con- 

 tinued through six periods of twelve days each, or seventy-two days. 



The cream was raised and butter made from it under similar con- 

 ditions during each jjeriod, the butter being made from the milk of 

 one day, and calculated for the period from the number of pounds of 

 milk required for one pound of butter. The total amount of fat 

 contained in each day's milk was ascertained by chemical examina- 

 tion. 



This same course of feeding and testing was repeated with Pet, 

 excepting when Bess had late hay Pet had early, and when Bess 

 had early Pet had late. This was for the purpose of equalizing the 

 influence of the variation of tempei'ature that might occur.
