united, so as to mutually cover each other, and they are firmly secured 

 by ligatures, &e. "When the parts are as thick as the little finger, and 

 they should not he thicker, a wire nail may he driven through the 

 junction. In performing this operation care must be taken that the 

 head of one tree exactiy balances the other. In employing this for 

 propagating rare plants, as soon as the union is well formed, the stock 

 is headed back to a Uttie above the union ; and the sort inarched is 

 separated from the parent as before directed. 



Sylvan Inarching {Crreffe Sylvain), Kg. LV., is best adapted for 

 forming lozenge-shaped openings in Pear and Apple-trees trained 

 in the form of vases, where much wood has to be supported by the 

 branches below. If performed at their points of contact, it puts their 

 sap in. communication and unites the different parts in a remarkable 

 manner. It may also be performed on trees with strong stems. In 

 such cases, bend their heads towards each other so as to cross ; make at 

 this point a notch in each (as at a), and unite the parts, as at 6 ; if 

 they are thick, secure the joint by a strong nail, which should always 

 be preferred to ligatures when there is much strain. The trees inarched 

 in this way make capital hedgerows.
