while the animals were becoming accustomed to their quarters, they were 

 given daily (5 pounds of middlings each and one feed of both corn fod- 

 der and silage. 



The actual experiment continued from January 6 to March 31, 1890, 

 eighty-four days. During this time each pair of heifers received daily 

 4 pounds of clover hay, and each heifer pounds of crushed oats and 

 all the silage or corn fodder it would eat, though with this full feeding- 

 more or less of the coarser parts of the silage or corn fodder were re- 

 jected. From January 6 to January 30 (first period) lot 1 received 

 corn fodder from Burrill and Whitman silage corn, and lot 2 silage 

 from the same corn. From January 30 to March 10 (second period) 

 lot 1 was fed corn fodder from Burr's White corn, and lot 2 silage 

 from the same. From March 10 to March 31 (third period) both lots 

 received corn fodder from Burr's White corn, the supply of silage being 

 exhausted. 



The corn of the fodder and silage fed during the first period was less 

 mature than that fed during the second "and third periods. The 

 corn fodder, which had been cut and left standing in shocks in the 

 field, was hauled from the field twice a week and cut up in the same 

 manner as the green corn had been in preparing it for the silo. 



The animals were weighed daily throughout the experiment, and every 

 precaution was used to have the weights taken under similar conditions 

 each day. "They ate with reasonable regularity, made good gains, and 

 were throughout the test in the best of health. Yet the table of indi- 

 vidual weights shows striking daily variations. An average increase 

 of 25 pounds per animal in one day, and again a decrease of 20 pounds 

 may be noted." It is apparent that a comparison of particular days 

 might be misleading. For this reason it was decided to take the aver- 

 age weight of five days preceding the beginning and ending of a given 

 period in calculating the gain or loss for that period. The results are 

 summarized in the following table :
