ACKNOWLEDGMENTS 



The authors desire to acknowledge courtesies so 

 numerous that to enumerate them is not possible, from 

 potato growers, government and state agricultural authori- 

 ties, dealers, officials of transportation companies and 

 others interested in agricultural uplift, both in America 

 and Europe. Every source of information has been drawn 

 on, and credit has been given in the text of the book 

 where quotations occur. 



They also desire to thank Mr. Cassius K. Michael, with 

 Doubleday, Page & Company, for many valuable sugges- 

 tions as to the compilation of the matter for this book 

 and his careful and conscientious work in editing and 

 preparing the copy for same.
