THE ART OF 



Remarks. — Veneering and side -grafting should be done 

 under glass ; the union of the graft is perfect in about six 

 weeks. Cleft-grafting in the forkings of the branches (see p» 

 106) is performed in the open air. Sub-varieties are grafted 

 on their type. 



Chamcecyparis Boursierii (vulg. Cupressus Lawsoniana), 

 C. JSTutkaensis (vulg. Thujopsis borealis), and Biota orientalis 

 are used as stocks for trees of similar habit and character. 

 The Betinosporas, which are dwarf er shrubs, according to the 

 classification of M. Carriere, are to be grafted on the Biota. 

 Thujopsis dolobrata and T. lagte-virens, which are also of only 

 moderate height in our gardens, should be grafted on the 

 Biota, or, better still, on the Thuja. 



Edible Chestnut. 



Stock. — Common chestnut (from seed), llode of Grafting 

 — Cleft-grafting ; in the forkings of the branches ; in the Eng- 

 lish fashion (in April) ; crown-grafting ; flute-grafting (in 

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



Remarks. — The chestnut also succeeds when grafted on 

 young oak plants which have been sown where they are to 

 remain permanently, or which have been freshly transplanted. 

 They should be grafted by ordinary cleft-grafting, or in the 

 forkings of the branches. When the sap commences to flow, 

 they may be branch-grafted on the sides under the bark (see p. 

 68.) It is then preferable to graft close to the ground. The 

 chestnut de Lyon is also shield-budded on the common 

 chestnut. 



The Oak. 



Stock. — Quercus robur pedunculata for the indigenous varie- 

 ties ; Quercus Cerris for the American kinds (from seed) ; 

 Quercus Ilex for the evergreen varieties. 2\Iode of Grafting. 

 — Cleft -grafting ; in the forkings of the branches (see p. 107) %
