The milk of both lots was richer in butter-fat during the 

 summer than during the winter trials lot II. shows much 

 more improvement in this respect than lot I.- a result no 

 doubt largely due to grass feeding. A comparsion of the two 

 lots, however, shows that lot I. still leads as far as the average 

 percentage of butter-fat goes. Thus, both with the smaller 

 allowance of concentrated food in the winter, and with the 

 larger allowance in the summer, the same lot of cows, in 

 spite of the change of food, has throughout given, on the 

 average, the richer milk. The inference, therefore, from 

 these results is that the quality of the milk, like the yield, is 

 also less dependent upon the feeding than upon the character 

 of the cows. From the butter-maker's standpoint, lot I. 

 gave slightly better results than lot II., but the difference is
