THE ART OF 



in any other way than by cleft-grafting, in consequence of the 

 slenderness of the scions. The scion should be grafted at the 

 height where it is desired the branches should spring from 

 the stock, as these kinds form a branching head without 

 growing much higher. Strong-wooded kinds, such as 

 0. Adami, binorus, odorans, grandinorus,sessiliflorus, and quer- 

 cifolius are propagated by shield-budding as well as by the 

 English method, cleft-grafting, and inlaying. The branches of 

 these are so vigorous that when grafted close to the ground 

 they will rise into tall standards. When the Cytisus is ampu- 

 tated for cleft-grafting or inlaying, it is absolutely necessary 

 to retain a bud at the top of the stock either opposite to or on 

 the same side as the graft, for the purpose of drawing the 

 sap to the scion. Also, when disbudding in spring, a few 

 shoots should be retained on the heel and pinched down to 

 two leaves; these are to be quite cut away when the shoot 

 of the graft is strong enough and at the period of the decline 

 of the sap. Destroy snails. 



Maple. 



Stock. — Species and type -varieties of the maples to be 

 propagated (from seed). Mode of Grafting. — Ordinary shield- 

 budding ; shield-budding with a reversed incision ; branch- 

 grafting with a heel (in August) ; close to the ground or as 

 standards. 



'Remarks. — The very vigorous kinds of maple are shield- 

 budded with a reversed incision (see p. 143). The branches 

 of the stock should be cut short as soon as it is budded. 

 The Acer marmoratum is grafted by shield-budding the 

 anticipative branches, or rather by side-grafting with branches 

 furnished with a base (see p. 69). This base, which is a 

 strip of bark, may be as much as 6 inches long if 

 necessary. As the heel of the stock has the disadvantage 

 of drying up very quickly, it will be necessary to retain for
