'GRAFTING. 39 



the same 'length, containing a bud ; this is instantly applied 

 -and fitted perfectly at top and bottom, and on at least one 

 -of its sides, and firmly bound with wet bass matting. This 

 mode may be practised in spring, and if it fails, a second 

 chance will be offered in July. The French are stated to 

 practise this mode on roses. 



The above are the principal modes ef inoculating adopt- 

 ed in practice, although Professor Thouin has described 

 no less than twenty-three distinct modes of operation. 



Dr. Van Mons buds his roses in June, so that they grow 

 nnd frequently blossom in the same year. He prepares 

 the young arid unripe wood by separating the leaves, leav- 

 ing only their footstalks ; in fifteen days after, their buds 

 are swollen, and are now fk for insertion: the stock is cut 

 t>ff six inches above the insertion of the bud, at the time 

 the operation is performed. They are bound with thin 

 strings of bass matting, previously drawn through a solu- 

 tion of alum and white soap, and dried, which renders 

 them impervious to water. 



SECTION IX. GRAFTING, 



Grafting is usually performed in spring. Professor 

 Thouin has described forty modes ; but the following will 

 answer for all general purposes: 



WHIP GRAFTING, or Splice Grafting. This mode is 

 practised principally on small stocks; and it succeeds best 

 when the scion and stock are of an equal size. 



The scion, which consists of the young wood of the for- 

 mer year's growth, is cut to the length of about four inches. 

 This and the stock are each to be cut sloping for an inch 

 or more, and tongued. Tonguing consists in cutting a slit 

 In the middle of the slope of the stock downwards, and a 

 corresponding slit in the scion upwards; both are now to 

 1.>e nicely joined, so that one of the sides, at least, if not both, 

 shall perfectly coincide, and to be securely bound with 

 n wet bass matting string, and covering with composition, 

 or with grafting clay. As soon as the scion and stock are 

 completely united, the string is to be removed. 



CLEFT GRAFTING. This mode of grafting is usually 

 practised on stocks of from one to two inches in diameter. 

 It is thus performed. The head of the stock is carefully 

 sawed ff at a part free from knots, and the top pared
