Jan.] THE FRUIT GARDEN. 37 



annuals, and other rare plants. You may likewise have several sorts 

 of dwarf fruit-trees, as early May and May-duke cherries, peaches, 

 nectarines, apricots, figs, grapes, gooseberries, currants, raspber- 

 ries, &c. 



The general construction of each sort of these frames is explained 

 under separate heads, according to the materials of heat used in 

 forcing them, viz: by dung-heat, bark-bed-heat, and by fire-heat. 



By Durtg-heat. — This is not only the most simple and cheapest 

 kind of forcing-frame in its construction, but also considerably the 

 cheapest in working, with respect to the article heat, as it may be 

 forced effectually by substantial linings of hot dung against the 

 back and ends. 



This frame is formed with an upright back and ends of pine 

 planking, and a sloping front of movable glass-lights; the length 

 may be ten, twenty, or thirty feet, or more; the width from three 

 to live, and five or six high: the frame work should be of two inch 

 pine planking, tongued, and closely joined, that no steam from the 

 dung may penetrate into the frame, raised five, six, or seven feet 

 high behind, and but ten or twelve inches high in front, raising 

 both ends answerable to the front and back; the glass-work to 

 range from the upright in front, sloping upward towards the back 

 wall to about a foot width at top, there resting the ends upon pro- 

 per frame work of wood; and bars or bearers, three inches width, 

 must range sloping from the back to front, for the support of the 

 lights, as in common hot-bed frames, and the top of all to be 

 boarded wind and water tight; within-side may be two or three 

 ranges of narrow shelves along the back and ends for pots of small 

 plants, and the bottom levelled, on which to place pots of larger 

 kinds; or you may have shelves rising one behind another, quite 

 from the front half way up the back; so may place the lowest plants 

 in front, the others in order behind them, rising gradually to the 

 tallest in the back row. 



From the above general sketch you will easily form an idea of 

 the proper construction of a dung-heat forcing-frame, which you 

 may improve as you shall see convenient. 



This kind of frame may be used with good success where dung 

 is plenty, and easily obtained; particularly for forcing roses or any 

 other small flowering plants, whose flowers have merit in beautv 

 or fragrance: — you may also try pots of dwarf-cherries, peaches, 

 &c, also pots of gooseberries, currants, and strawberries, carna- 

 tions, pinks, and the like; having all the sorts in pots separately, 

 and in which they are to be placed in the frame. 



The season to begin to work this frame is January and February, 

 and may be continued occasionally till May; but for any kind of 

 fruit-trees, the beginning of February is time enough, though those 

 plants of any kind that are designed to be forced may be placed 

 in the frame a month or two before forcing time, to be occasional I \ 

 protected with the glasses in hard frosts; but at other times let 

 them enjoy the full air till you begin forcing. 



The method of working this frame is thus: after having plain I 

 the pots of plants in regular order, the tallest behind, and the lowest
