GRAFTING CONIFERS. 49 



or those placed in frames for the purpose, where the 

 grafter can control the temperature and supply moisture 

 as required, until a perfect union between stock and cion 

 has taken place. Grafting conifers in the open air may 

 sometimes be done quite successfully, especially upon 

 some of the species 

 of arbor - vitaes, 

 yews, larch, and 

 taxodiums, but as 

 a rule it is best to 

 use small stocks, 

 and have them pot- 

 ted in the fall, and 

 then keep them in 

 a cool green-house 

 or frames, and then 

 graft as they com-

 in winter or early 

 spring, the cions 

 being either in 

 a dormant condi- 

 tion, or the buds 

 but slightly ad- 

 vanced.

always be of the 

 previous season's growth, and a portion of the leaves left 

 attached. The stocks also must not be denuded of their 

 foliage, and a convenient method of grafting is what may 

 be termed a side graft, the cion being inserted into a 

 cleft, made in the side of the stock, and held in place 

 with the usual ligature of bass bark as in budding. The 

 plants are kept in a somewhat confined atmosphere, and 

 frequently syringed overhead until the cion has united, 

 then the stock above it is cut away,
