It is now a very simple matter to calculate the amounts of 

 total dry matter, and of digestible protein, carbhydrates and fat, 

 contained in the daily ration per head. We obtain the following 

 results : 



The cows weighed by estimate 800-900 lbs. each, and hence the 

 total of the above ration has been re-calculated to the basis of 

 1,000 pounds live-weight to render it comparable with the ration 

 recommended by Wolff, which is placed below it. It will be 

 noticed at once that the two differ considerably, but any remarks 

 on this difference will be deferred until the remaining rations 

 have been considered. 



The average yield per day and head of the whole herd was 

 about 6.3 quarts of milk. 



The second farm which was visited was that of Mr. Edward 

 Norton, of Farmington. Here the cows Avere mostly Guernseys 

 and Jerseys. The milk is sold to the Farmington Creamery and 

 hence care is taken to feed nothing which could injure the flavor 

 of the butter. For this reason no oil-cake is used. The fodder 

 of twenty-six cows, in all stages of lactation, was weighed. This 

 included nearly all the cows in milk. The average weight of the 

 animals was, by estimate, 925 pounds. The following feeding- 

 stuffs were used : 



Low meadow hay, cut in July, 1880. The cows had just been 

 changed to this from better hay, and ate rather less than usual in 

 consequence. 



Corn fodder from northern corn, cut in September, 1880. Three 

 bushels of seed per acre in drills 2 J feet apart. 



Oats, maize meal, and wheat bran. The oats and maize are 

 ground together in the proportions of ^ oats and f maize, and one 

 bag of this mixture is added to two bags of bran, this being esti-
