38 THE FRUIT GARDEN. [Jan. 
in front, &c., then put on the lights, and having sufficient qu^intity 
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 oiF wetj 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 eftectually 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 tiie manner of wall-trees to a 
trellis, ranged five or six inches from the back erection, in which 
may be 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 good 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 kidney-beans, peas, strawberries, salading, &c. 
By Bark-bed -heat. — 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 may 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 maybe constructed either nearly like the dung-
