Ring-Grafting. — Last spring, I obtained a slight success in some experi- 

 ments I made in grafting rings of bark taken from one sort of tree or shrub, and 

 putting them upon another. The object was to cause the sap to circulate through 

 a channel different to its own, and thus, by inducing a commingling of fluids, to 

 cause it to break out into a fresh growth foreign to either. The idea was origi- 

 nal : and finding the operation, as far as regards the bark uniting, to be a practi- 

 cal one, I have thought, that, by explaining the process to the readers of •' The 

 Florist," it may lead others to try and find out where a union may be effected ; 



for trees and shrubs widely differing in character and species can be made to 

 unite, and possibly some good cross, or sport, may be the result. 



Mr. Scott has recently stated that he saw the lilac {Syringu vulgaris) grow- 

 ing upon the ash {Fraxinus excelsior) in the Jardin des Plantes at Paris. I 

 have tried the same union by ingrafting, and had the plant growing for two or' 

 three years ; but it ultimately died off. This union suggested to me the idea of 

 trying experiments by ring-grafting. Accordingly, in the month of April, or, as 

 a rule, as soon as the sap was found to be freely circulating in the different sorts 

 to be operated upon, I selected branches of the different kinds to be tried. I 

 made two horizontal cuts at one and a half inch apart through the bark, and a
