THE AItT 0? 



Manetti, just as the latter helps out the dog-briar in the open 

 air. The stock, potted in autumn, is cleft-grafted under glass 

 in spring following, about February. The stock having been 

 cut obliquely, the scion is inserted at the bottom or at the top 

 of the incision. A bud or shoot should be retained on the 

 stock opposite to, or on the same side as, the graft. When 

 the union of the graft is ascertained, when the buds of the 

 scion swell, and are ready to break, it is gradually exposed to 

 the air, and ultimately removed to a cold frame. The young 

 branches being sufficiently hardened, and often in a flowering 

 condition while it is still spring, the subjects may be removed 

 into the open ground. 



Fir. 



8 tod:. — The type of the variety to be propagated, whether 

 Abies, Picea, or Tsuga (from seed). Mode of Grafting. — 

 Veneering, close to the ground (in February and September, 

 under glass) ; herbaceous cleft-grafting in the crown (in May) ; 

 cleft-grafting with a terminal bud (in April). 



Remarks. — Grafting under glass is performed on young 

 vigorous plants raised in pots. The other two methods aro 

 practised in the open air, and if properly done, the tree grafted 

 will grow quite as straight as if raised from seed. Grafting 

 with a terminal bud is described at page 102. Abies nobilis is 

 generally more vigorous when grafted on Abies pectinata than 

 when raised from seed. The best stocks for each tribe of the 

 firs are — Abies pectinata for the Abies ; Abies picea and 

 sapinette for the Piceas ; Abies canadensis for the Tsugas ; 

 and Abies Douglasii for the Pseudo-Tsugas. 



Sophora. 



Stoch. — Sophora japonica (from seed). Mode of Grafting.—* 

 Shield-budding (in July and August) ; cleft -grafting (in 

 April) ; close to the ground, or as standards.
