GRAFTING 75 



owner instead of devoting a great deal of time and 

 hard labor to raising and collecting his crop will have 

 abundant time for going to town and interesting 

 himself in civic affairs. 



A large new field of observation will relate to the 

 selection of nut bearing grafting stocks. Which ones 

 will furnish dwarf nut trees, which ones will give 

 prolific bearing, which ones will increase the range 

 of soils in which a certain choice variety may be 

 raised these and other questions remain to be set- 

 tled and increase the interest in the subject of nut 

 culture at the present moment. 



A species of tree with a top naturally smaller than 

 that of the stock upon which it is grafted may not 

 be fruitful. After the time when top and stock bal- 

 ance each other the stock demands so much from 

 the top in the way of nourishment that little fruiting 

 energy may be left. Species of other hickories 

 grafted upon pecan stocks furnish an example, but 

 some of the hazels make an exception. On the other 

 hand, a top naturally larger than that of the stock 

 finds it an easy matter to satisfy the root of the 

 stock and we have prolific bearing. Apples and pears 

 grafted upon dwarfing stocks furnish an example. 

 The pecan hickory when grafted upon the water 

 hickory will sometimes grow rapidly for a few years 

 and then die back if the stock stands where its feet 

 are very wet, but on higher land this is said not to 

 be the case. 



When using the various hybrid hickories as scions 

 we shall have to learn which parent species gives the
