PUBLISHERS' INTRODUCTION. 



The dairy industry has advanced with greater strides 

 during the last two decades than any other of the great 

 agricultural interests. Formerly it was mainly confined 

 to New England and the Middle States. Now, however, 

 in the prairie States dairying has become a leading in- 

 dustry, and it is notable that in the more recently settled 

 territories of the Northwest, the cheese factory or cream- 

 ery is one of the earliest features in a new settlement. 

 During the period referred to, the entire business of 

 dairying has become almost revolutionized. The exten- 

 sion of the associated system, the invention of new and 

 greatly improved ii^plements and machinery, and new 

 processes, have occasioned these radical changes. The 

 present work embodies a full knowledge of improved 

 methods, and all that is latest and most valuable in 

 dairy lore. Its author has long occuined an advanced 

 position in the march of dairy improvement, as a prac- 

 tical dairyman, a scientific investigator, and a writer for 

 the press. The book embraces the entire subject, and 

 will prove a trustworthy hand-book to every one who 



is interested in any department of dairying.
