 trees are propagated in the same Tray as those which are 

 grown for fruit. 



The Poplar. 



Stock. — White poplar; black poplar; Lombardy poplar; 

 aspen, according to the varieties or sub-varieties to be propa- 

 gated (from cuttings). Mode of Grafting. — Cleft -grafting (in 

 March and April) ; crown-grafting (in April and May) ; close 

 to the ground or as standards. 



Remarks. — Subjects newly transplanted may be used as 

 stocks, and cuttings may also be employed for the same 

 purpose. This observation applies equally to the willow. 

 Photinia. 



Stock. — Common quince ; quince of Angers (from cuttings 

 with a heel or hillock-layers). Mode of Grafting. — Shield- 

 budding in the open air (in August) ; cleft-grafting in the 

 open ah- in April ; close to the ground. 



Remarks. — In operating in the open air, the leaves of the 

 scion-bud or branch should be removed. In grafting under 

 glass they are retained ; in the latter case the union of the 

 graft is complete in five or six weeks. Disbud thoroughly in 

 the open air, and pinch the young graft -shoots down to a 

 foot to make them branch. Grafting under glass is done in 

 February and September. 



The Pine. 



Stock. — Select the type of the variety to be propagated, or 

 an allied species bearing the same number of leaves in each 

 fascicle (from seed). Mode of Grafting. — Veneering; cleft- 

 grafting ; close to the ground (in March and September, under 

 glass). Terminal cleft-grafting with herbaceous scions (in 

 May, in the open air). 



Remarks. — Grafting under glass is done in spring or autumn, 

 the air being excluded in the usual way. Terminal herbaceous
