METHODS OF GRAFTING.

the albiuninous deposit of the sap, wliicli unites the 

 graft to the new wood of the stock. 



It is not unfrequeiit tliat tlirifty grafts of two or 

 three years' growth are blown out of the cleft in the 

 stock ; and it will always be found on examination that 

 only the bark and extreme rind of sap-wood have 

 united, while on the remaining surfaces, woody matter 

 has been deposited without adhesion. 



When grafts are procured from a distance, or it is 

 necessary to keep them some time before use, they 

 should be cut in winter, or early spring, before the 



A buds have swollen, and 



packed away in moder- 

 ately damp sand. If al- 

 lowed to be too wet, 

 they will decay, and if 

 exposed to evaporation, 

 they will wither. The graft should 

 be in a less advanced 

 condition than the 

 stock, as during the 

 process of adhesion, 

 evaporation from the 

 bark goes on rapidly 

 when the sap in the 

 graft is active, and 

 death ensues, be- 

 cause the supply can not be maintained. 



Grafting of the pear is usually performed only on 

 large-sized stocks or upon bearing trees, except in
