LUTHER BURBANK 



If a visitor who observes my cherry trees in 

 the blossoming time chances to visit my orchards 

 a little later, at the time of fruiting, he will prob- 

 ably be disposed to admit that my method of 

 experiment has had very satisfactory results. For 

 the cherries that grow on my trees are among the 

 largest and most luscious, as well as the most 

 abundant, that have ever been produced. 



The visitor will perhaps be surprised to find 

 many scores of cherries quite different in appear- 

 ance growing on the same tree. This, however, is 

 the result of grafting. 



Seedlings grown from seed produced on a 

 single tree may vary widely, but the immediate 

 fruit of any individual tree is fairly uniform, 

 unless the tree has been grafted. 



But trees on my farm always are grafted, so 

 the phenomenon of divers varieties of fruit on the 

 same tree is a familiar one. 



AN UNSTABLE RACE 



The cherry is at best a variable fruit. Like 

 most orchard fruits, it cannot be grown depend- 

 ably from seed. But, of course it is necessary in 

 producing new varieties to work from seedlings, 

 and from the standpoint of the experimenter who 

 wishes to produce new varieties, it is fortunate 

 that the tendency to vary exists. For, as our other 

 experiments have taught, in the case of plants
