of cotton seed meal and corn meal, and in second period pure corn 

 meal. Three cows used in the experiment, each period of feeding 

 being four weeks. During the last two weeks of each period a 

 record was kept of the milk produced, and of the cream and butter, 

 the milk being analyzed also. 



Time: Winter, 1885-6. 



Results published: Report M. E. S., 1885-6, pp. 65-72. 



(6) Feeding Experiment. 



Object: Comparison of wheat straw and a nitrogenous grain 

 ration with timothy ha}' and corn meal, as food for growing steers. 



Plan: Two lots steers, two in each lot, saiie weights of hay and 

 straw fed, and same weights of grain, only the lot eating straw 

 received some cotton seed in place of part of corn meal fed 

 to lot eating timothy. 



Time: Winter, 1885-6. 



Results published: Report M. E. S., 1885-6, pp. 73-76. 



(7) Field Experiment. 



Object : The practical effect of different forms of phosphoric acid 

 in crop production, also of a complete commercial fertilizer against
