piled by Henry and Morrison.' A total of eighteen 

 separate experiments, involving the use of 280 pigs, was 

 involved in this study. The pigs averaged 175 pounds 

 at the beginning of the trials, which covered feeding 

 periods ranging from 63 to 98 days. The experiments 

 were made diu-ing the winter and in each case old corn 

 only was used. One lot of pigs was fed ground corn and 

 another similar lot shelled corn. In all the experiments 

 the corn was supplemented with wheat middlings in the 

 ratio of 2 parts corn to 1 part wheat middlings. The 

 shelled corn was fed alone and dry, and the middlings 

 were mixed and fed wet with a small quantity of water.

As a rule, these experiments were with large well-grown 

 pigs fed to rather heavy weight. The averaged results 

 show the rate of gain to have been increased practically 

 15 per cent by grinding, and the amount of feed required 

 to produce 100 pounds of gain reduced practically 6 per 

 cent. These results were quite consistently shown in the 

 individual experiments.
