ACKNOWLEDGMENTS 



In the preparation of this work the author has had 



v;the co-operation of many of the leading hop growers 



and dealers in two continents, to whom his debt is most 



s^ gratefully acknowledged for facts, experiences and 



J;; photographs. The United States department of agri- 



^ culture has furnished certain illustrations, while official 



<r statistics and returns have been supplied by the United 



^: States treasury department, the English board of 



agriculture and the German foreign office. The 



somewhat scanty literature on the subject has been 



freely drawn upon,. including nearly all the works listed 



in our bibliography. During the past fifteen years that 



the author has been collecting data on this subject, in 



connection with "Our Hop Growers' Exchange" 



department in American Agriculturist, many invaluable 



statements have been received and these have also been 



fully employed, particularly numerous essays of 



practical men on the cost of growing hops. Special 



services have been rendered that should have special 



recognition.
