PREFACE TO NINTH EDITION 



This book was prepared primarily for the School of 

 Agriculture of the University of Minnesota, where it has 

 been used as a textbook since it was first published. It is 

 the result of the development of the system of teaching 

 at this school and is intended for students of the high 

 school grade. In this the ninth edition a few changes 

 have been made to bring it up-to-date in the matter of 

 methods of culture and varieties recommended. 



In previous editions I have taken pleasure, as I do 

 now, in acknowledging the assistance which I have re- 

 ceived in many ways in preparing the manuscript for the 

 first edition of this book from Prof. Harry Snyder, the late 

 Dr. Otto Lugger, the late Major A.. G. Wilcox, and my 

 former assistant, Prof. R. S. Mackintosh, now Professor 

 of Horticulture at Auburn, Alabama. In preparing this 

 edition, I have been helped by Mr. A. R. Kohler, Assistant 

 in Horticulture.
