282 Structure for Peaches and Vines. 



covered with boards, and a wire trellis on one side (z), for 

 vines, and glass frames on the other side (k), to admit the 

 light, and retain the heated air from the flue. The vines should 

 be planted in the inclosed border, which should not be very 

 deep, and might be paved at bottom and well drained, so as to 

 limit the supply of nourishment, and check the overexuberance 

 of growth in both peaches and vines. The roots of the vines 

 may be kept apart from those of the peaches by an under- 

 ground division of slates, or a brick-on-edge wall ; indeed, it 

 would be an advantage to limit the roots of each particular 

 vine and tree in the same way. As there would be some 

 difficulty in glazing the round ends, they may be boarded and 

 covered with peaches, leaving only the straight part for vines. 



When the peach-trees are in blossom, they may be pro- 

 tected by a moveable coping, and by a canvass or gauze 

 covering. Standard peaches may be planted against the glass 

 (&), with stems sufficiently long to reach the height of the 

 structure, and their heads may be trained down the opposite 

 side (I). 



This structure should be rounded at the top, for the more 

 easily training the trees over it ; and it should be well painted 

 or coated over with gas tar or pitch every two or three years, 

 to insure durability, and destroy insects. If each side of the 

 structure be six feet high, both sides will be equal to a wall of 

 twelve feet ; and I think the mode of heating will be found 

 superior to that adopted in the common mode of constructing 

 hot-walls. Pots of strawberries might be forced along with 

 the vines, and steam might be produced by pouring water into 

 the trough formed on the top of the flue (d). Dampers might 

 be introduced at the place where the flues divide (m), so as to 

 throw the heat wholly, or more or less, to one side, at pleasure. 

 A walk (n) might go round the piece of ground inclosed; 

 and this ground might be slightly cropped; but it will be 

 better neither to stir it deep, nor to grow any thing on it, but 

 merely to keep it clear of weeds. Care also must be taken 

 not to disturb the partition between the roots (o) ; and if, as I 

 would recommend, each separate tree be partitioned off, the 

 ground should neither be dug nor cropped, but manured on 

 the surface, and slightly pricked up with a fork two or three 

 times a year. 



I think a structure of this kind would have a good effect 

 on each side of the main walk in a garden, as a substitute for 

 an espalier rail. Both furnace and chimney-top might be 

 connected with the outer wall of the garden, so as not to be
