4 PREFACE. 



ised to write for the book about the Babcock 

 test. 



If I can give my brother workers some ideas 

 that will enable them to do better work, and 

 can induce a small percentage of the dairymen 

 to apply the scale and Babcock test to their 

 individual cows and dispose of the unprofitable 

 ones, I shal-1 feel that I have accomplished 

 some good.
