A Stage of Progress 



This hybrid dahlia from Mr. Burbank's colony probably 



illustrates one of ths stages through which the cultivated dahlias 



have passed within comparatively recent generations in the course of 



their development. Here, it will be seen, the rag flowers are 



encroaching on the center of the flower head, and the 



contrast between this double flower and its 



wild prototype is very striking.
