flue thus encloses a pit 27 ft. long, and 8 ft. 6 in. wide, in which 

 the trees are planted. Between the back flue and the back wall 

 there is another border, in which standard trees are planted : 

 these are trained to a trellis against the back wall. The trellis 

 to which the other trees are trained is nearly horizontal ; and it 

 extends over the whole of the house, except 3 ft. of the back 

 border (which, being covered by a framing of boards, serves for 

 a walk), and that part of the flue which passes along the front of 

 the house. This trellis is 3 ft. 6 in. high at the back, and it 

 declines to 2 ft. 6 in. in front. 



A vine, pruned on the spur system, is trained beneath each 

 rafter ; the shoots are confined within a breadth of 18 in. or 20 in.; 

 consequently, the obstruction of light is not so great as to be very 

 detrimental to the peach trees. A great extent of surface is thus 

 obtained for the training of peach trees, with the advantage of 

 having a crop of grapes without any additional expense. Such 

 houses, however, are ill adapted for very early forcing : when 

 peaches are required earlier than the end of July, one of the 

 houses described in the Encijclopcedia of Gardening will be much 

 preferable. Another disadvantage is, that, about the time the 

 grapes are setting, and, consequently, require a close warm atmo- 

 sphere, the peaches will be about stoning, when a free circulation 

 of air is indispensable to them ; but this difficulty might be in a 

 great measure overcome by care and attention. It should never 

 be attempted to have very late grapes in a house of this sort. 



An orange apricot tree, growing against a building in the 

 kitchen-garden, deserves to be mentioned on account of its 

 great size. Its branches cover a space of 42 ft. by 18 ft.; and, 

 being still full of vigour, it most likely will extend many feet 

 further. 



A large chapel is now in the course of erection near the man- 

 sion, under the direction of Bonomi.

Art. II. On the Necessity of young Gardeners studying the Natural 

 System of Botany, and Vegetable Physiology. By A Young Gar- 

 dener. 



Though I perfectly agree with the opinion you have so often 

 expressed, as to the utility of gardeners making themselves ac- 

 quainted with all the different arts and sciences, yet I think you 

 will allow that the first they should study should be those im- 

 mediately connected with their own profession, and that botany 

 is at least one of the most important, if not of the very greatest 

 importance, of these.
