amounts of the different kinds of grain consumed by the two groups 

 during the two years is of more than ordinary interest. In the first 

 place, barley had to be discontinued because the price rose beyond its 

 feeding value, so oats was substituted. Second, during the second year 

 another change was made by withdrawing bran and replacing it with 

 flour middlings. The latter is a better feed but only a trifle more than 

 half the quantity was fed. During the second year Group IV had 612 

 pounds of corn and 655 of oil meal, while Group V had 1,764 pounds of 

 corn and 444 of oil meal. There is almost conclusive evidence that 

 too much corn and too little oil meal was fed, and also that too many 

 changes in the grain mixture were made.

In the spring of 1911 there was no call for calves because so much 

 material had accumulated in the analytical laboratory and so many data 

 had been acquired that it was necessary to postpone the feeding experi- 

 ments for a year. Letters, however, were received from farmers who 

 had previously sent calves, expressing a desire to furnish their usual 

 quota. 



During the latter part of April, 1912, another call was made for 

 beef -bred calves. This letter brought only a few. Another letter was 

 sent and a few more came. As a last resort a prominent breeder of 

 beef cattle was engaged to solicit shipments, and by June 23, 21 calves 

 were secured. This was a new experience and quite the reverse of that 

 when Group V was being formed. There is also ample evidence that 

 it was quite the reverse of what would have happened had a group 

 been called for in the spring of 1911.
