PREFACE 



This book is intended to give brief and practical 

 suggestions on the growing, breeding and marketing 

 of potatoes. It is written especially for the practical 

 farmer and the student who may wish concise informa- 

 tion on the potato without having to read many mis- 

 cellaneous sources of information, especially experiment 

 station bulletins which, although highly valuable, are 

 likely to contain much detail. 



The chapters on breeding and varieties occupy an 

 unusually large proportion of the book. This is for the 

 reason that these subjects have been treated in potato 

 literature much less than methods of culture, and the 

 general interest in them has called for this extended 

 discussion to meet not only the necessities of the case 

 but also the public demand. 



I have been glad to place in the hands of Doctor Bar- 

 rus and Mr. Dean the chapters on Diseases and Field 

 Methods respectively. These men have had broad ex- 

 perience in their lines and are thoroughly competent to 

 discuss them. 



The author wishes, also, to acknowledge the valuable 

 aid of Professor Herrick in reading the manuscript on 

 Potato Insects, and Mr. A. C. Fraser and Mr. J. J. 

 Pollock for valuable assistance.
