cut sloping at an angle of 45, the plant to be 

 fixed on the sloping part. These blocks can then 

 be placed on the lower end, which should be cut 

 horizontally, to allow them to stand firmly in that 

 position.

Propagation : ly Grafting. The graft- 

 ing of the Plum is performed in precisely 

 the same manner as the Pear or the Ap- 

 ple, and at a similar period. The Brus- 

 sels stock is principally used by our nur- 

 serymen; but for such gross sorts as the 

 Washington, the Magnum Bonum, &c., 

 it is a question whether the Muscle stock 

 would not be fitter. We need not en- 

 large here on the process, which will be 

 found in detail under the head GRAFTING-. 



Budding. The same may be said of 

 this process. See BUDDING. 



Seed. This is resorted to in order to 

 procure new varieties ; and to accomplish 

 this, of course, seed from choice varieties 

 is obtained. The mode of sowing, rear- 

 ing, &c., will be found detailed in the 

 articles PEACH and PEAR. 



Culture during the Growing Period. 

 As with the Peach, the Nectarine, Pear, 

 &c., so with the Plum. The first pro- 

 ceeding of the season is disbudding. 

 About the beginning of May the trees 

 burst forth into a great amount of spray, 

 and much of this will be ill-placed ; and, 

 indeed, if well-placed, much too crowded. 

 We are, of course, speaking of wall or 

 espalier trees, for there the most atten- 

 tion is requisite. A progressive disbud- 

 ding is best, the first consisting in merely 

 removing the foreright and back shoots, 

 unless, as observed with regard to the 

 other stone fruits, vacant spaces occur, 

 when an ill-placed shoot is better than 

 none. Shortly after this period, if the 

 trees be strong, gross shoots or robbers 

 will show themselves, which, when about 

 six inches long, should have the points 

 pinched off. In a few weeks more, ano- 

 ther disbudding will be expedient, and 

 by this time shoots of a proper character 

 for final reservation may be determined 

 on. The latter may be carefully tied or 

 trained as soon as convenient, and every 

 shoot of a doubtful character, in the 

 thinning out, may have the point pinched 

 off. The rest of the proceedings, indeed,
