D'ALBRET'S PRACTICB— SHIELD-BUDDING. 



inch above the bud and sloping. In extensive operations the cutting 

 back is done roughly at three or four inches above the bud, in order 

 that the stump may serve as a support to the shoot produced by the 

 bud, which for a time is fastened to it. 



Shield-budding without alburnum (Fig. XLVI. b. — Oreffe en icusson 

 dinui de bois), — This is employed for propagating delicate trees and 

 shrubs with slender wood and thin tender bark. The form of the 

 shield is usually traced with the blade of the grafting knife, cutting 

 completely through the bark ; then having removed a portion of that 

 which is above it, we press the shield between the fingers, and with a 

 jerk detach it from its position along with the small fleshy growing 

 point ; if by mischance the latter is bruised or remains attached to the 

 alburnum, the shield must be destroyed and another substituted. To 

 avoid this inconvenience we employ a fine wire, as indicated at b, which, 

 by pulling the two ends, is made to glide along the alburnum, easily 

 detaching the shield with the growing point adhering to it. 



Inverted j_ budding (Fig. XLVI. a). — ^Prepare a shield the point of 

 which shall be above the eye — see a. Eaise this shield by means of a 



wire, as above explained; make in 

 the ^ock an opening by the cut 

 indicated in the figure, and there 

 insert the shield by introducing its 

 point at the base of the opening ; 

 unite the parts, and secure the 

 whole by a ligature, which should 

 commence below the eye. This 

 mode of budding is preferable to all 

 others for propagating the finest 

 varieties of Oranges and Olives, and 

 all tender trees with viscid sap. 



Square Shield- budding — (Fig. 

 XLVII. c. Greffe en ecusson, dite 

 emporte piice). — From a strong tree, 

 remove a square patch ; raise from a 

 strong branch another piece of the 

 same shape, but larger, and fur- 

 nished with an eye ; fit this piece into 

 the place of the first ; and. cover it 

 with a piece of paper, pierced with 

 a hole for the eye, securing the 

 whole by a ligature. This is to be 

 employed for trees with very thick 

 bark and large eyes; such as Walnut 

 and Mulberry-trees. It may be performed in spring, for budding with 

 the pushing eye ; or even with the dormant eye, in August, or later.
