PREFACE 



In most of our agricultural schools and colleges 

 many short-course students now make up a large 

 part of the total registration, and in dairy work it 

 is doubtful if any other class of students accom- 

 plishes so much in the same period of tuition. 

 Perhaps the greatest difficulty or drawback to the 

 average short-course man is his lack of prelimi- 

 nary school training. He can do manual work, but 

 lack of experience in answering questions causes 

 his failure at examination time. He knows the 

 work, but cannot express his views in writing. 



Then there are those long-experienced, practical 

 buttermakers who wish to better their positions by 

 trying civil service examinations. They read all 

 current literature and know the answers in a cer- 

 tain way, but cannot express their thoughts as they 

 should. 



It is for this class of men, and out of sympathy 

 for their needs, that the author has seen fit to com- 

 pile this little series of question compends. 



All modern literature on buttermaking has been 

 consulted freely, with the hope of making the work 

 more thorough and with the hope of being of the 

 greatest service to those of our associates in dairy 

 work.
