ON HARNESSING HEREDITY 



that the bees make the colors. The flowers which 

 grow in the bright light need their brilliance to 

 attract the insects; flowers in the shade are more 

 easily observed if they are light or white in color; 

 it is all a matter of advertising contrast; and, 

 throughout ages and ages, each particular flower 

 lias been striving to perfect a color contrast scheme 

 of its own. It may be that the combination of sun 

 and soil makes possible brighter colors than the 

 combination of shade and soil; but wind-loving 

 plants, like corn and trees, which grow in the sun, 

 do not bedeck themselves in colors only the 

 flowers which find it necessary to attract the 

 insects. 



"In practice, at any rate, the color of a flower 

 is one of the reliable guides in the study of its 

 life-history." 



Taking the orange daisy and its white cousin 

 side by side, we see at once a family resem- 

 blance. The leaf formation, the root formation, 

 the arrangement and the number of petals, the 

 arrangement of stamens and pistils, bespeak the 

 fact that here are two plants of a kind; one orange 

 and one white; the white one taller a little, more 

 graceful perhaps, and slightly less hardy; but 

 cousins, beyond doubt, having within them many 

 parallel strains of heredity. 



Let us assume, then, that the orange of the
