DEDICATION 



One of my teachers, above all the others, is 

 responsible for my love of taxonomic science. 

 And, as for that, the same one laid the whole 

 foundation for my love of general horticulture. 

 This man has never received the praise rightly 

 due him for his efforts in behalf of his students 

 of whom I am but one among hundreds. I 

 know I have been no special credit to him; and, 

 like many of the others, I have seemed unappreci- 

 ative. Now, however, as I am about to publish 

 a book, the inspiration Jor which came long ago 

 from him, I wish to acknowledge my sense of in- 

 debtedness to him and my high personal esteem 

 for 



EDWIN A. POPENOE 



Formerly Professor of Horticulture and Ento- 

 mology, now Professor of Entomology, in the 

 Kansas Agricultural College.
