4. With milk albumen as the source of animal food, 2 experi- 

 ments : both favorable to the wide nutritive ratio. 



5. With milk albumen as the source of the animal food and with 

 corn oil added to the meals used in the mash in moderate quantities, 

 3 experiments: one favorable to the wide nutritive ratio ; two favora- 

 ble to the narrow. 



6. With beef scraps and milk albumen both, in the proportion of 

 four to three, as animal food, 6 experiments : one favorable to the 

 wide nutritive ratio ; five favorable to the narrow nutritive ratio. 



Summing up these results, we find the wide nutritive ratio has 

 given the greater number of eggs in eighteen out of the thirty-six 

 experiments, an equal number in one. The narrow nutritive ratio 

 has given the greater number of eggs in seventeen experiments. 



The number of eggs produced daily has been 

 Number of Eggs at the following rates per 100 hens : 

 Per 100 Hens. i. For the narrow nutritive ratio, from 11 to 

 60, the average being 35^. 

 2. For the wide nutritive ratio, from 18 to 54, the average being 

 3634. 



For the narrow nutritive ratio the food cost per 

 Food Cost of the egg has been from .6 to 2.4 cents, the average 

 Eggs. being 1.05 cents: for the wide nutritive ratio, 



from .39 to 1.4 cents, the average being .83 cents. 



The cost of the food per single hen daily has 

 Cost of Feeding been as follows : for the narrow nutritive ratio, 

 Hens. from .22 to .47 cents, average of 36 experi- 



ments, .32 cents ; for the wide nutritive ratio, 

 .16 to .43 cents, average of 36 experiments, .27 cents. 



The health of the fowls used in these experi- 

 Effect of the Ra- ments has been in general good, although in 

 tions on Health, one of the experiments, the one with the smallest 

 egg yield shown, there was considerable trouble 

 from roup. As is always the case, there have been some losses by 

 death. The total numbers thus lost have been ; on the wide nutritive 

 ratio, 24; on the narrow nutritive ratio, 20. In some cases it was 

 quite apparent that the death of the fowls was due to digestive dis- 

 turbances, but that it was due to such causes was by no means 

 certain in all cases. 



These results do not indicate any considerable difference in the 

 safety of the two systems of feeding. It has been noticed, however,
