tions, and the time comes when it must reproduce itself and 

 it goes right at it. 



Mr. Judd: Is there a stage where the juice of the corn 

 will turn to acid and another stage where it turns to sugar? 



Prof. Haecker: Prof, Farrington is the chemist, I am 

 simplj giving my opinion. But I see that men planting corn 

 in that way seem to get more feeding value out of it per acre 

 than do those who are planting it in the orthodox way. 



Mr. West: What value would you place upon cob meal? 

 In this vicinity the corn and cob are being ground to take 

 the place of oats and bran. Will they do that? 



Prof. Haecker: No, sir; it will come very near taking the 

 place of oats, but not of bran by a long ways. It is not worth 

 more than half what bran is. 



Mr. Judd: Isn't it true that a hundred pounds of corn 

 and cob meal will make about as much milk fat, as a hun- 

 dred pounds of clear corn meal? 



Prof. Haecker: I rather think it might be worth a little 

 more. In the first place, it keeps the grain loose, so that the 

 juices can penetrate the meal and digestion is more perfect; 

 in the second place, the cob itself has some feeding value. 



A Member: I think it was said yesterday that the test 

 could not be increased by feeding. I want to tell a little ex- 

 perience. I had been feeding shock corn in the fore part of 

 the winter, and clover hay, and no other feed until about the 

 first of January, when I commenced with turnips, what they 

 call milk turnips. My test before that was 4.5, and since 

 that it has been up to 4.65, and I don't know how to account 

 for it except by the turnips or some mistake. I have always 

 had the idea that turnips would increase the quantity of 

 milk, but not the test. It did increase the quantity of milk 

 in this case and the test too. 



Prof. Haecker: Nothing has surprised me more since 

 we have been carrying on these experiments than the varia- 

 tion in the test; not only from week to week, but from day 

 to day and month to month. We are very careful about our 

 tests and yet we find the greatest variations in different 

 animals in the herd, the food and conditions being the same.
