38 THE FRUIT GARDEN. [Jan. 



in front, &c, then put on the lights, and having sufficient quantity 

 of fresh stable-dung, full of heat, prepared as for common dung 

 hot-beds, let it be piled up close against the outside of the back 

 and ends a yard wide at bottom, drawing it gradually into a foot 

 width at the top of the frame, finishing it somewhat sloping, to 

 throw oft' wet; observing, that according as the dung settles or 

 sinks down, a fresh supply must be added at the top to maintain 

 the lining to the full height of the frame. 



The lining will effectually throw in a fine growing heat, and 

 soon set all the plants in motion; observing to give air in the 

 middle of fine days by sliding one or more of the lights a little 

 down, especially when the plants begin to push; give also moderate 

 watering occasionally in mild sunny weather, and cover the glasses 

 in cold nights with mats. 



In three or four weeks, when the heat begins to decrease consi- 

 derably, it must be renewed, either by entire fresh dung, or if new 

 dung is scarce, by shaking up the old, taking the worst away, and 

 mix the remainder with a due quantity of new, working the whole 

 again in a pile close against the back and ends as before, which 

 work must be repeated every three- weeks or month, or as often as 

 you shall see occasion, for the heat must be constantly preserved 

 to a regular brisk temperature. 



A frame of the above construction may be appropriated entirely 

 for fruit trees, planting them in a border prepared within the frame 

 against the back part, and trained in the manner of wall-trees to a 

 trellis, ranged five or six inches from the back erection, in which 

 maybe planted early dwarf-cherries, peaches, nectarines, apricots, 

 grapes, figs, currants, &c, so maybe worked by dung-heat against 

 the back of the frame as above directed; beginning in February, 

 and continuing the glasses on, as well as support the dung-heat 

 until May, and there is no doubt, with good management, but that 

 the different sorts of fruit may be brought to perfection early. 



But a dung-heat forcing-frame may be constructed of more 

 capacious dimensions, to admit of making a substantial hot-bed of 

 dung internally, both to produce an increased degree of heat, and 

 wherein to plunge pots of several sorts of flowering and esculent 

 plants to bring them forward in growth, being assisted also with a 

 lining of hot dung applied to the«exterior of the back part of the 

 frame, as explained in the foregoing; and for the internal hot-bed 

 should form a bottom pit of proper width, length, and depth, making 

 the bed therein a yard depth of <jood hot dung, covering the top 

 with light dry earth, or old or new tan-bark, six or eight inches 

 thick, in which to plunge the pots of flowers, or those of early 

 esculents, such as kidnev-beans, peas, strawberries, salading, &c. 



Ihj Jiark-brd-hcnt. — This kind of forcing-frame, or rather forcing- 

 house, is worked by aid of a tanner's bark hot-bed, formed in a pit 

 within -side the whole length. 



This frame mav be formed either of wood or brick-work, and 

 fronted, &c. with sashes of glass like the former; the length may 

 be ten, twenty, or thirty feet, or more, eight or ten wide, and six 

 or eight high; and may be constructed either nearly like the dung-
