JAN.} THE FRUIT GARDEN. 33 



This frame, or forcing house, must be formed of brick-work, at 

 least the back or main wall, for the convenience of having fire and 

 flues, and the whole front, &c. must be glass, like the other sorts ; 

 the length may be from twenty to forty feet, or more, though one 

 fire will not warm more than that length ; the width may be from 

 five or six, to twelve or fifteen feet, and heigh eight or ten. It may 

 be contrived either of moderate width for one row of trees only, 

 to range against the back wall ; or may be capacious enough to have 

 a range of trained wall-trees behind, as just mentioned, and some 

 small half standards, ranging also from the back to the front. 



If it is therefore intended to have a narrow Frame for only a row 

 of trained trees behind, the width from four to five or six feet is 

 sufficient, having the back or main wall formed of brick or stone, 

 as aforesaid, eight or ten feet high, with several flues withinside, 

 returned over each other, running the whole length of the wall ; 

 in the front must be a low wall a foot high, on which to lay a plate 

 of timber, and from which, are ranged glass frames or lights in one 

 continued slope to the top of the back wall, there received into pro- 

 per frame-work ; but for the greater convenience, the lights may 

 be in two tiers or ranges, an under and upper tier, the upper range 

 made to slide up and down over the others, but so as all the glass^ 

 work can be moved away occasionally, to admit the full air to the 

 trees after the work of forcing ; the whole bottom-space within 

 this frame must be of good loamy earth, or any good garden 

 mould, two spades deep, which must be dug or trenched in the com* 

 mon way ; then plant a range of trees behind, towards the wall, 

 and two or three yards asunder, erecting a trellis behind them, 

 upon which to train the branches as against a wall or espalier ; be- 

 sides these trees, there may be other inferior plants set in the bor- 

 der or in pots, in front of the trees, as strawberries, dwarf kidney- 

 beans, dwarf peas, Sec. dwarf roses, or the like, that Will not rise 

 high enough to shade the fruit-trees in the back range. 



A frame of this construction, forty feet long, may be worked by 

 one fire ; but if longer, two furnaces for fires will be requisite. 



But to have a more capacious Frame both for trained trees and' 

 low standards, it may be of any length from twenty to fifty feet or 

 more, but must be ten or fifteen feet wide, having an upright back 

 wall of brick ten feet high, with flues as above directed, and a low 

 wall in front one or two feet high, on which is erected upright glass- 

 work, four or five feet perpendicular, and from the top of these, a 

 sloping roof of glass frames, continued to the top of the back wall, 

 supported upon proper bearers three feet, or three feet six inches 

 distance, having the top glasses in two ranges, an under and upper 

 range, as before advised, both of which, and those of the upright ia 

 front, made to slide, and move away occasionally : in this frame 

 there will be room to walk under the glass-work in any part, and 

 there will be also due room for the trees, both dwarfs and low stand- 

 ards ; and then having the whole ground-space withinside of loamy, 

 or other good earth, as in the other frame, you may plant your 

 trees, some in one range against the back wall, as peaches, necta- 

 rines, apricots, grapes, figs, &c. six or eight feet asunder, erecting
