SELP-INAECHING. 325 



make upwards of thirty feet of wood in the same season as that of the 

 operation. Mr. Abraham has produced examples of his manner of 

 proceeding ; hut his method of grafting is not so good as that of the 

 French. He employs tongue-grafting; they merely apply the two 

 surfaces, and keep them in contact with a bandage. The disadvantage 

 of summer tongue-graftiag is that it wounds each of the branches 

 operated upon, is tedious, and needless. The only object of a tongue is 

 to keep a scion firmly in its place, and this is necessary where ripe- 

 wood grafting is employed with loose scions, because the union is in 

 that case slow, and the scions are apt to be displaced by accident ; but 

 no such risk is run in summer-grafting, and a sounder joint is made 

 without the tongue, 



A method of propagating Camellias, by putting the end or 

 heel of a scion into a vessel of water, mentioned in the 

 Gardeners' Magazine, ii. 33. is essentially the same as 

 inarching. The water communicated to the scion through the 

 wounded -end supplies it with that food which, under natural 

 circumstances, would he derived from the roots of the plant to 

 which it belongs. 



In the succeeding pages is given the substance of D'Albret's practical 

 directions for the principal kinds of grafting employed in France : — 



Inarching {Oreffe par approehe) is distinguished by the circumstance 



that both the individuals intended to be united live on their own roots, 



and mutually co-operate in forming a union. It is thus that we 



increase trees and shrubs which cannot be propagated by other modes, 



or at least not by any that are so well adapted for bringing plants 



rapidly to maturity. By some modes we can make large trees assume, 



in parks and forests, picturesque forms, or curved and angular timber 



useful for the navy and the arts. M. Thouin has described thirty-nine 



modes of inai-ehing: a few only possess general interest. Inaiching is 



best performed when the sap is in fuU flow in spring. All the modes 



require ligatures, and some little apparatus for bringing the two 



portions into shape. "When high stocks are destined to form curved 



timber, &c., take care to allow some weak shoots and branches to grow 



along the st«ms, in order to increase their thickness ; without, however 



robbing the parts operated upon. ' ' 



Inarching Stems, for the purpose of supporting and invigorating 



them (see Fig. LIH.), is a modification of the Qreffe Michaux. 



Select a strong tree, near which there is a slender one of the same kind 



or if not, plant one, and when well estabUshed, bend it against the 



stem of the stock, in order to determine the most convenient place, for
