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.
