butter or cheesy matter? This subject has been thoroughly investigated in 

 Germany, and German chemists have come to the conchision that they can in- 

 crease the quantity of milk by high feeding, but cannot improve the quality. 

 Let us not misunderstand this point. A cow fed with nutritious food gives, 

 we will say, milk containing a certain amount of fat and casein. Now if atc 

 give this cow very much richer food, we shall probably get a much greater quan- 

 tity of milk, but it will not be richer than before ; a quart of it will contain 

 about the same quantity of fat and of casein. 



We cannot make a hutler cow or a cheese coio at pleasure by simple variation 

 of food. These are peculiarities of individuals and of breeds. 



The result of investigations made in Germany in regard to the influence of 

 variations in the kind of food on the quality of the milk, are well shown in the 

 following table : 



Prof. lugersoll and myself tried one experiment to determine the influence 

 of food upon milk. We took two cows, "Fanny 2" (grade Ayrshire), and 

 "Irene 2" (grade Alderney). The cows were fed 5 pounds of cut corn stalks, 

 2 pounds of cut oat straw, and 2 quarts of a mixture of two parts Indian corn 

 meal and one part shorts, twice a day. This was poor feed. After they had 

 eaten it for five days, I took samples of milk from each cow and analyzed them. 

 The cows were then put upon high feed, viz. : the same amount of cut feed as 

 before, and 40 pounds of sliced turnips, with G quarts of tlie mixed feed. After 

 five days' feeding I took samples of the milk, which I analyzed. The results 

 appear in the following table :

It must not be inferred from these experiments that the quality of food has 

 no influence upon the amount of milk given or its richness, because it is not
