HOW AN APPLE-TREE IS MADE S3 



Winesap. Neither does anyone know why of two seeds 

 that look alike one will unerringly produce a cabbage 

 and the other a cauliflower. So accustomed are we to 

 these results that we never challenge a twig of apple or 

 a seed of cabbage: we assume that the twig or the seed 

 "knows." Nor have we yet approached this question in 

 our elaborate studies of plant-breeding. Here is one of 

 tjie mysteries that baffles the skill of the physiologist and 

 chemist, yet it is a mystery so very common tljat we 

 know it not, albeit the life on the planet would otherwise 

 be utter confusion.
