GRAFTING AND BUDDIXG 303 



Thus it will be seen that every organic structure 

 on the earth, every plant and animal whether of 

 earth, sea, or air, including man himself, is wholly 

 dependent upon the food always first developed 

 in the leaves of plants. 



But to return to our cions a twig of the Bald- 

 win apple, grafted on a wild crab apple tree, will 

 produce Baldwin apples, and not wild crab 

 apples. Moreover, the Baldwin apples thus 

 grown will be identical in appearance and flavor 

 with those that grow on the tree from which 

 the cion was cut. This seems very mysterious 

 but the like of it is matter of every day obser- 

 vation in the orchard of the up-to-date fruit 

 grower. 



Nevertheless, the question has more than once 

 arisen as to whether cion and stock may not exert 

 upon each other an influence of a profoundly 

 modifying character. 



That such may be the case, to the extent of 

 producing a poisonous influence, has been ob- 

 served in the case of grafts between species 

 somewhat distantly related. It has been ob- 

 served, for example, that some of the English 

 plums unite with the peach, and do fairly well 

 for a time, while others refuse to unite under any 

 circumstances, and still others when budded or 

 grafted on a peach stock seem to poison the
