ACKNOWLEDGMENTS 



In the preparation of this work the author has had 

 the co-operation of many of the leading hop growers 

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

 gratefully acknowledged for facts, experiences and 

 photographs. The United States department of agri- 

 culture has furnished certain illustrations, while official 

 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. 



From the state of Washington came important 

 helps by E. Meeker and James Hart, also Major R. M. 

 Hornsby of British Columbia. Oregon: A. J. Wolcott, 

 H. J. Ottenheimer. California: Lilienthal & Co. of San 

 Francisco, and the Pleasanton Hop Company afforded 

 every possible assistance in the way of photographs, 

 statistics of coast crops, etc.; Daniel Flint, the hop 

 pioneer, was a liberal contributor from his experience; 

 also L. F. Long and others, while Horst Brothers 

 placed at our disposal all the experience and resources
