Stove orchids. Not possessing much beauty, 

 but are interesting, curious little plants. They j 

 tlirive best upon blocks of wood with a small ! 

 portion of moss tied to the block. The best ; 

 form of the block is a round one, with the top ' 

 cut sloping at an angle of 45 degrees, the j 

 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 I 

 to stand firmly in that position.

Propagation. By Grafting. The 

 grafting of the Plum is performed in 

 precisely the same manner as the Pear 

 or the Apple, and at a similar period. 

 The Brussels stock is principally used 

 by our nurserymen ; but for such gross 

 sorts as the Washington, the Magnum 

 Bonum, etc., it is a question whether 

 the Muscle stock would not be litter. 

 We need not enlarge here 011 the pro- 

 cess, 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, 

 rearing, ifcc., will be found detailed in 

 the articles Peach and Pear. 



Culture dining the Groicing Period. 

 As with the Peach, the Nectarine, Pear, 

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