NOTE TO STUDENTS 



In order to derive the utmost possible benefit from 

 this paper, you must thoroughly master the text. While 

 it is not intended that you commit the exact words of the 

 text to memory, still there is nothing: contained in the text 

 which is not absolutely essential for the intelligent dairy- 

 man to know. For your own good never refer to the ex- 

 amination questions until you have finished your study of 

 the text. By following this plan, the examination paper 

 will show what you have learned from the text.
