THEORIES OF DEVELOPMENT 



shall take up the practical aspects of Mr. Bur- 

 bank's work, in effect going with him into the 

 fields and observing the carrying out of the prac- 

 tical work of the horticulturist. It will be con- 

 venient first to examine his method of caring for 

 seeds and the nature and development of seed-

 with him into the orchard, the small-fruit garden, 

 the vegetable and flower gardens, and the lawn 

 and dooryard, gaming characteristic glimpses of 

 his manifold activities. 



It is obvious that with the space at command 

 it would be impossible to name each and every one 

 of the plants with which Mr. Burbank has experi- 

 mented effectively. At best we can mention only 

 the more typical or the more spectacular cases. 

 But I would again remind the reader that a very 

 complete exposition of his entire lifework has 

 been given by Mr. Burbank himself in a series of 

 volumes, twelve in number, illustrated by no fewer 

 that twelve hundred and sixty beautiful color 

 plates. To this work the reader who wishes a 

 more extensive presentation of the work of plant 

 development as carried out by the Santa Eosa ex- 

 perimenter may turn with full confidence and with 

 pleasurable anticipations.

 present book, although necessarily condensed in 

 its treatment, endeavors to give the essentials of 

 Mr. Burbank 's methods and results, and that the 

 illustrations of Mr. Burbank 's work here pre- 

 sented are drawn from a first-hand study of his
