GRAFTING AND BUDDING 299 



family of stone fruits plum with apricot, peach 

 with almond, and the like. But if you attempt 

 to ignore the larger barriers, and strive to graft 

 seed fruit upon stone fruit apple or pear on 

 plum or peach your effort will result in failure, 

 just as Dr. Carrel's experiments resulted in 

 failure when he attempted to transpose the 

 organs of cat and dog. 



At all events, we are commonly able to make 

 such grafts as we choose between different species 

 of the same plant genus ; and we may reasonably 

 infer that the same thing might be possible in the 

 case of animals. 



It has been found in plant life where there 

 has been much crossing either naturally or by 

 intent in the past that most striking individual 

 differences appear. Some individual seedlings 

 among any lot of such crossbred plants (all of 

 which may have come from the seeds of a single 

 variety) will thrive when grafted on certain other 

 species or varieties even better than on their own 

 roots, while other individual varieties refuse to 

 combine or grow under any conditions; for in- 

 stances, the common French prune thrives better 

 on almond roots than on its own, the golden drop 

 plum will not live when grafted on the peach, 

 while some of its nearest relatives, the common 

 French prune and others, grow, thrive, and pro-
