that heifer, if you develop an 8,000-pound coav? I would 

 emphasize that side of this subject, — that you know your 

 cows, know them individually, know how much they can 

 make use of, and know what that will do. 



Question. What grain do you feed? 



Mr. Ellis. As I said before, our mixture at present 

 is 1,150 pounds of bran, 450 pounds of middlings, 850 

 pounds of corn meal and 400 pounds of cotton-seed meal. 

 We var}'^ that somewhat, as the cost of feed varies. This 

 year we are feeding corn meal where ordinarily we should 

 not because of poor quality of ensilage. 



Question. Do you feed gluten meal, — it is cheap 

 enough. 



Mr. Ellis. We do at times. 



Afternoon Session. 

 The meeting was called to order at 2 o'clock by First 

 Vice-President Sessions, who called on Professor Brooks 

 of the Massachusetts Agricultural College to explain the 

 exhibit of corn in the hall, made in connection with the 

 meeting of the Board. In response to the call, Professor 

 Brooks spoke as follows : — 



Experijnents with Corn, based on Exhibit of Oro]) of 1902. 

 I presume you have all had opportunity to examine the 

 exhibit of corn grown during the past j^ear in the experi- 

 ment of which I am going to speak. The exhibit includes 

 the entire product of each plot in the field. The area of the 

 plots is one-twentieth of an acre each. The printed slips 

 which have been circulated, and of which I think each of 

 you has one, give much of the information which is needed 

 for an understanding of the significance of the varying jdeld 

 on the different plots. The kind and quantity of manure or 

 fertilizer applied to the several plots is shown by the labels 

 accompanying the exhibit. The printed slip, which is given 

 below, also gives this information as well as a statement of 

 the yields of each plot.
