nurse or stock can be removed, the cion having taken root. 

 Root-grafting, described on a previous page (see Figs. 103, 

 104, 114), is virtually a grafting of cuttings. In other cases, 

 union with an uncongenial stock is facilitated by allowing 

 the cion to project downwards beyond the point of union, 

 and to stand in the soil or moss or dish of water. (See, 

 also, page 112.) Fig. 137 is a good illustration of the 

 practice. The cion extends into the soil nearly as far as the 

 root itself. After union has taken place, the 

 lower part of the cion is removed. This 

 method can be used for some magnolias, 

 mulberries, birches, and many other plants 

 of which some kinds root with more or less 

 difficulty. "Bottle-grafting,'" described in 

 most of the books, is essentially this method, 

 modified by letting the end of the cion, or a 

 portion of the bandage, drop into a 

 bottle of water. 



Inarching. -Inarching, or grafting 

 by approach, is the process of graft- 

 ing contiguous plants or branches 

 while the parts are both attached to 

 their own roots. When the 

 parts are united, one of them is 

 severed from its root. Fig. 138 

 explains the operation. In this 

 case, the larger plant (upon 

 the left) is designed for the stock, 

 plant has united, it is cut off just below the union and it 

 thenceforth grows upon the other plant. Limbs of contigu- 

 ous trees are sometimes grafted in this way. It is the pro- 

 cess employed by nature in what is called natural grafting 

 (Fig. 82). Grape-vines are often inarched. A thrifty young 

 branch of a fruit tree may be inarched into the stem of a fruit 

 upon the same tree, thus supplying the fruit with additional 

 food and causing it to grow larger than it might if untreated.
