Four thoroughbred Jersey cows were used in the experi- 

 ment. Before beginning the test the milk from each cow 

 was carefully weighed for four days. The cows were then 

 divided into two lots of as nearly equal milk produciug ca- 

 pacity as possible. 



Kate Hazen 1st and Ransom's Pride were called for con- 

 venience lot 1, Hattie Signal 2d, and Miss Hattie Pogis were 

 called lot 2. 



Up to the beginning of the experiment all of these cows 

 had received the same feed. 



During the experiments both lotsweregiven the same quan- 

 tity of grain and fodder, the oaly difference in the feed being 

 in the Rye and Ensilage. The regalar grain feed per day was 

 four quarts of corn and cob meal and two quarts of cotton 

 seed meal, oat straw and shucks and during the latter part 

 of the experiment pea hulls were used as dry fodder. The 

 grain feed was made small in order to more clearly show the 

 effect of rye and ensilage. The low yield of milk is due 

 partly to the small grain feed and partly to the cold and 

 rainy weather. 



The experiment was begun on the morning of February 

 3d, and continued until the night of March 2d, making 28 

 days. 



It is divided into two periods of fourteen days each. Du- 

 the first period lot 1 was fed rye, and lot 2 ensilage. During 

 the second period lot 1 was fed ensilage and lot 2 rye. 



At the beginning of the test, the quantity of rye fed per 

 day to each cow was 30 pounds. This was increased to 40 

 and on the fifth day of the test to 50 pounds. Kate Hazen 

 1st, failed to eat all of her rye and for the remainder of the 

 experiment only 40 pounds of rye per day was fed to each 

 cow. At the beginning of the 2d period the rye given to 

 lot 2 was raised in the same way to 50 pounds. Both 

 cows in this lot failed to eat all of the 50 pounds, and the 

 quantity given per day for the remainder of this period was
