GRAFTING 113 



same lot and same variety and all put in by myself, 

 the work being carefully done. I might say in refer- 

 ence to this experiment that previous to the cutting 

 of the patches on the stock ahead of time -we had 

 had little success in budding the Persian walnut and 

 had given up budding it. Later in the season in this 

 latitude when the sap is not so active the patch 

 should be cut ahead two weeks. I think probably 

 three or four days in the lower south will be time 

 enough, when the sap is very active, and probably 

 a week ahead later in the season/' 



Parallel with this Jones method of bud grafting 

 was one experience which I had with a shagbark 

 hickory scion graft. While examining some hickory 

 grafts about two weeks after they had been put in 

 and which had not made a start, one of my men 

 accidentally hit a scion with his elbow and knocked 

 it out. He freshened the cut surface of the scion a 

 bit with his jack-knife and stuck it back into the 

 cleft in the stock from which it had been removed. 

 A few days later this graft sprouted and grew while 

 none of the others, which had been left undisturbed, 

 made any sort of a start. I had intended to make 

 use of this observation, but developed the method 

 shortly afterward which made it unnecessary. In 

 the case of the hickory accident quoted the principle 

 involved apparently includes that which gives suc- 

 cess in the Jones method of budding. The stock 

 with greater vitality than the graft had put out an 

 abundance of repair material. When the shaped end 

 of the loosened scion had been freshened and re-
