PREFACE vii 



is the adjunct. In other words, the stress is laid upon the plants as 

 domesticated and cultivated subjects. Special efforts have been made to 

 portray the range of variation under domestication, and to suggest the 

 course of the evolution of the greatly modified forms. Garden plants are 

 worthy subjects of botanical study, notwithstanding the fact that they 

 have been neglected by systematists. It is desired to represent the 

 plants as living, growing, varying things, rather than as mere species or 

 bibliographical formulas. 



The Editor desires to say that he considers this book but a beginning. 

 It is the first complete survey of our horticultural activities, and it is 

 published not because it is intended to be complete, but that it may 

 bring together the scattered data in order that further and better studies 

 may be made. A first work is necessarily crude. We must ever improve. 

 To the various articles in the work, the teacher of horticulture may assign 

 his advanced students. The Editor hopes that every entry in this book 

 will be worked over and improved within the next quarter centmy.
