At all events they need not be untangled by 

 the plant developer. For him it suffices to recall 

 the names and characteristics of the various 

 species and to concern himself with such selec- 

 tions among their offspring as will produce races 

 blending these characteristics in new and desir- 

 able combinations. 



But, indeed, the experiment became even more 

 complex as it proceeded to additional stages. 



For by this time I was in possession of several 

 other species of amaryllis, and these also were 

 worked into the combination by hybridizing 

 with different members of the fourth-generation 

 hybrids already introduced. 



The new species would be crossed with various 

 of the hybrids to accentuate certain qualities of 

 size of flower or color or prolific bearing; and the 

 new hybrids thus produced would in turn be 

 interbred, until the tangled web of their heredity 

 was quite beyond unraveling. 



GETTING RESULTS 



But at each stage of such a series of experi- 

 ments the plant developer of course watches for 

 results and is guided by results. 



He has learned by this time of the tendencies 

 to variation that exist. He has gained a clear 

 idea as to the various new races that he hopes
