obtained from the plots where stable manure and insoluble phos- 

 phates had been used. 



THE RELATIVE UTILITY OF DIFFERENT FORMS OF PHOSPHORIC 

 ACID IN FIELD EXPERIMENTS. 



Results: The phosphoric acid of bone and South Carolina 

 rock was quite freely appropriated by oats, peas and corn. 



EXPERIMENTS IN FEEDING LAMBS. 



The effects of liberal feeding versus moderate feeding for 

 growing early lambs was studied. The results were very much 

 in favor of liberal feeding. The sheep and lambs payed at the 

 rate of $71.60 per ton for the extra grain used. 



EXPERIMENTS IN FEEDING COLTS. 



Oats were compared with other mixed grain foods for pro- 

 ducing growth with the result that a greater growth was pro- 

 duced by the mixed grains and hay than with oats and hay. 



EXPERIMENTS IN FEEDING SWINE. 



Many feed experiments have been made with swine. The- 

 more important questions studied were : 



(1) The value of corn meal compared with whole corn for 

 growth. 



(2) Raw versus boiled potatoes for growth. 



(3) The most efficient ratio of nutrients in a ration. 



(4) The relation between the nutritive ratio and character of 

 the growth. 



(5) The relative value of animal and vegetable protein. 



(6) The effect of much water in food upon assimilation. 



(7) Experiment in feeding different breeds. Two each of 

 Berkshires, Cheshires, Poland China, Chester white, and York- 

 shires were used. The rations consisted of wheat middlings 

 and skimmed milk, liberally fed according to age of animal. 

 Daily growth, Cheshires, 1.23; Yorkshires, 1.14; Chester white, 

 1.08 pounds; Poland China, i.oi ; Berkshire, I pound. 



Results: (i) The same weight of whole corn produced, 

 almost the same growth as when the corn meal was fed.
