Pure Bred and Hybrid Compared 



The front box shows second-generation hybrids of the 

 Balloon Berry and Hawaiian raspberry, like those shown in the 

 preceding picture. The box in the rear shows the Hawaiian rasp- 

 berry unmodified. A comparison of the two types of leaves 

 gives a good idea of the modification effected by hybridiza- 

 tion. There is, of course, a considerable range of 

 variation among the second-generation hybrids, 

 giving opportunity for selection.
