combination with other foods has superior merits for egg 

 production as compared with wheat. 



2. The rations fed to the fowls in houses Nos. 3 and 4 

 were relatively high in ash and low in fiber. Milk albumen 

 was the animal food used. This was selected on account of 

 the low percentage of fat it contains, and the rations fed to 

 the fowls in both of these houses were characterized by much 

 lower fat contents than the rations fed to the fowls in houses 

 Nos. 1 and 2. As in the experiment previously described, 

 the fat content of the two rations used in houses Nos. 3 and 

 4 was equalized by the addition of corn oil to the one nat- 

 urally lower in fat. ^^Tieat was the leading grain in the 

 ration fed to the fowls in house IsTo. 3 ; corn the leading whole 

 grain fed in the other house, No. 4. The results with the 

 fowls in these houses, like the results obtained in houses Nos. 

 1 and 2, afford a basis for estimating the relative value of 

 wheat and corn, but with a relatively low percentage of fat 

 in both. The nutritive ratios used in this experiment were, 

 for the ration containing wheat, 1 to 4.54; for the ration 

 containing corn, 1 to 6.28. The egg product in this experi- 

 ment was as follows: for the first period, January 25 to 

 April 28, inclusive, for the wheat ration .49 and for the corn 

 ration .47 eggs per hen day; for the summer period, April 

 28 to September 5, inclusive, for the wheat ration .35 and 

 for the corn ration .46 eggs per hen day. In other words, 

 100 fowls, laying at similar rates, would have produced on 

 the wheat ration 49 eggs per day during the winter period 

 and 35 eggs per day during the summer period. On the 

 corn ration, the same number of fowls would have laid 47 

 eggs per day during the winter period and 46 eggs per day 

 during the summer period. It will be noticed that the result 

 in the winter experiment is favorable to the ration contain- 

 ing the wheat. In the summer, on the other hand, it is 

 favorable to the ration containing the corn. In the experi- 

 ments reported last year the numbers of eggs both in the 

 winter and in the summer period were greater on the wheat 

 ration, although the cost per egg was less on the corn than 

 on the wheat. In the experiments of the past year the gross 

 cost of food per egg produced on the wheat ration has been
