THE BURBANK CHERRY 



already described, it is only when a tendency to 

 vary from a fixed racial type has been brought 

 about by hybridization, or otherwise, that the 

 material is furnished upon which the experi- 

 menter can build. 



In the case of the cherry, all the familiar 

 varieties are the result of hybridizing experiments 

 performed either consciously or unconsciously in 

 the past. 



By working with the seed of any existing 

 variety, one secures plants of numerous types that 

 suggest different possibilities of development. 

 The Ideal Cherry 



In the course of my experiments, however, I 

 have had occasion to bring together, through 

 artificial poUenization, various standard varieties 

 of the cherry, and, although I have not found it 

 necessary to send to foreign countries, yet the 

 stock with which I have worked represents races 

 which have been developed in regions as widely 

 separated ^s Russia, the eastern United States, 

 California, and Japan. 



It has been my aim to combine the desirable 

 qualities of different races of cherries from these 

 widely separated regions, and the task here, as 

 in so many other instances, has chiefly consisted 

 in persistent selection among multitudes of seed- 

 lings of widely diverse types.
