344 LUTHER BURBANK 



trated by photographs showing many types of 

 hybrid blackberry and raspberry canes and 

 leaves. 



The diversity of second-generation hybrids 

 was illustrated by such other examples as the 

 Phenomenal berry and two other hybrids listed 

 in the catalogue under separate numbers and 

 announced as of the same origin. 



But, for that matter, the segregation and 

 recombination of characters in the second gen- 

 eration, leading to endless diversity of variation, 

 was illustrated in the case of every new variety 

 named in the entire catalogue, with the exception 

 of the Paradox and Royal walnuts and the 

 Primus berry, these alone being first-generation 

 hybrids. 



Quotation has already been made as to the 

 "million kinds" of blackberry hybrids of the 

 second generation. It may be added that in the 

 supplement of 1894 a photograph was repro- 

 duced that showed a "sample pile of brush twelve 

 feet wide, fourteen feet in height, and twenty- 

 two feet long, containing sixty-five thousand 

 two and three-year-old hybrid seedling berry 

 bushes (forty thousand blackberry-raspberry 

 hybrids and twenty-five thousand Shaffer- Gregg 

 hybrids) all dug with their crop of ripening 

 berries."
