226 LUTHER BURBANK 



When I came to know more about plant de- 

 velopment this tendency to variation was re- 

 called, and here, as always, a fruit of this 

 tendency should furnish material for the develop- 

 ment of improved varieties. 



In due course I worked with the various culti- 

 vated varieties of blackberry, and soon developed 

 some improvements, particularly with reference 

 to the size of fruit, its flavor, and lengthening the 

 season of fruit bearing. 



One of the improved varieties with which I 

 worked had been lately introduced under the 

 name of the Early Harvest; another was named 

 Wilson Junior. But the most notable results 

 attended the use of the native species, and in par- 

 ticular the introduction of foreign species from 

 remote parts of the earth. 



As early as 1879 I was earnestly working on 

 varieties of blackberries, and of raspberries as 

 well, that were obtained from my collector in 

 Japan, combining these with other wild and cul- 

 tivated varieties from various sources. 



The first really notable success, however, came 

 about through selection, without the aid of hy- 

 bridizing, from a berry that I had introduced 

 from India. This berry, in recognition of its 

 origin, was named the Himalaya, sometimes 

 shortened to Himalya.
