of bark raised up from the stock, differs from laying, 

 inarching, and grafting, inasmuch as the ascending 

 or wood sap is in no way concerned. The bud is 

 fixed entirely by the sap of the bark, with probably 

 some aid from what may ooze out of the soft wood. 



But the scallope, escutcheon, or French mode of bud- 

 ding, in which a section or scallope of bark and wood 

 containing a bud is taken from one tree, and applied 

 to a part of the stem of another tree, where a similar 

 scallope had been removed, acts exactly on the prin- 

 ciple of the graft, and is best performed in the graft- 

 ing season. 



The common mode of budding, which is the 

 simplest, and with most plants the most certain, is 

 performed when the young shoots of the season have 

 nearly completed their growth; then the buds are 

 formed, and the bark separates freely from the young 

 wood. Scallope-budding is chiefly used in propa- 

 gating roses, as in them the bark does not separate 

 readily ; but in green-house plants it might be used 

 in the case of plants which are too small for separat- 

 ing a single bud, but Avhere a scallope containing two 

 or three buds may be taken off and inserted. In this 

 way more plants might be got from a given extent of 

 shoot, than either by grafting, inarching, or laying, 

 or even propagating by cuttings. 



Formerly it was thought grafting and budding 

 could only be applied to ligneous plants ; but now it 

 is found that annuals, biennials, and perennials, may 

 be budded or grafted. The Georgina is sometimes
