ANIMAL GROWTH AND NUTRITION. 251 



more can be done with an acre of corn, as compared with the 

 results of the crop from an acre of grass ; but you liave said 

 nothing about the relative cost of producing the two crops : 

 does not that come in as an important element ? 



Mr. Sanborn. Certainly it does. 



Question. Taking into account the labor, is there so 

 much more advantage in raising grain-crops than hay-crops? 



Mr. Sanborn. If we should go into the discussion of cost, 

 there would be so many elements brought in that it would 

 be interminable. To make a short statement, I will say, that, 

 since I have changed my practice, the actual net revenue of 

 the farm has been larger than at any time previous. The 

 income is increasing each year with the increase of tillage. 



Dr. Wakefield. Will you state to the audience what 

 you consider the cheapest food to make the best butter? 



Mr. Sanborn. I had some cows that were in lots of two, 

 consuming about forty-five pounds of corn-fodder and straw 

 mixed, and five pounds each cow of cotton-seed and corn 

 meals. I put four cows upon hay without any grain, fifty 

 pounds of hay costing thirty-seven and a half cents. The 

 mixed food cost twenty-nine cents, — eight cents less; and 

 the milk-flow, in exact figures, went down on the four cows 

 ten per cent. I find the cheapest food for a good quality of 

 butter is corn-fodder. The cheapest combination I can make 

 to maintain a good quality of butter is corn-fodder, cotton- 

 seed and corn meals. I give them a foddering of straw every 

 day. 



Dr. Wakefield. No hay ? 



Mr. Sanborn. Let me say that I always, when I have 

 clover-hay, put in a foddering of clover-hay. I would never 

 farm without clover-hay. I do not put in any English hay.
