cerning It, 



" Neither is it possible to fix an absolute standard as 

 to the most profitable daily quantity of milk. All that 

 we can do is to watch vigilantly every circumstance that 

 may tend to augment or decrease the performance of

 Beauty of form and beauty of color are, of course, de-

 without detracting from economic value, they are most 

 desirable ; but if In seeking them we lose sight of the 

 chief aim, we not only do injury to our own interests, 

 but permanently detract from the average value of the 

 whole race. 



" The question of size is, doubtless, of great import-

 decision concerning it ; at least I am aware of no experi- 

 ments that do more than to Indicate which is the wisest

 to be relied on at all, they seem to point to medium size 

 as the most desirable. Further experiments as to the 

 advantage or disadvantage of large size are needed. 

 Certain arguments in favor of the smaller size are 

 worthy of consideration. In the case of pure breeding,
