OF PLANTING TREES FOR FORCING. 227 



useful things may be raised under the centre 

 frame, such as small salads, early rhubarb for 

 tarts, tarragon, mint, &c. 



When the centre of the house is left open for 

 forcing generally, many sorts of fruits may be 

 forced therein, either in pots plunged in the 

 earth, or established trees in a bearing state 

 turned out of the pots and planted immediately 

 without disturbing the balls; to effect this the 

 more easily, let the earth in the pots become 

 rather dry, and they will come out of the pots 

 with little trouble, and without injury to the 

 balls. 



Let me here remark, that it is by no means a 

 good method to force trees the first year after 

 planting, particularly when removed from nur- 

 series without balls, therefore in all new- planted 

 houses it is desirable for the future welfare of 

 the trees to let them remain open and fully ex- 

 posed till the following season, and then only 

 a small quantity of fruit should be allowed to 

 remain on each tree, particulary if the trees 

 had not received more than two years training 

 when planted.
