In that sense, then, artificial selection created 

 the Shasta Daisy, but the forces evoked were those 

 that nature provided, and the entire course of my 

 experiments might be likened to an abbreviated 

 transcript of the processes of natural selection 

 through which species everywhere have been 

 created, and are to-day still being created, in the 

 world at large. 



New Races of Shastas 



Once the divergent traits of these various 

 strains fiad been intermingled, the conflict set up 

 was sure f o persist generation after generation. 



Each individual hereditary trait, even though 

 suppressed in a single generation by the prepo- 

 tency of some opposing trait, strives for a hearing 

 and fends to reappear in some subseqiient gen- 

 eration. 



So the plant developer, by keenly scrutinizing 

 each seedling, will observe that no two plants of 

 his hybrid crop are absolutely identical; and by 

 selecting and cultivating one divergent strain or 

 another, he may bring to the surface and further 

 develop traits that had long been subordinated. 



Seizing on these, T was enabled, in the course 

 of ensuing years, to develop various races of the 

 Shasta, some of which were so different that they 

 have been given individual names. The Alaska, 

 for example, has even larger and more numerous
