Jan.] THE FRUIT GARDEN. 37 
annuals, and other rare plants. You may likewise have several sorts 
of dwarf fruii 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 explain- 
ed 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 Dung-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 five, 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 proper 
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 foreing-frame; which you 
muy 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 beauty 
or fragrance: — you may also try pots of dwarf-cherries, peaches, 
Ice. also pots of gooseberries, currants, and strawberries, carnations, 
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 occasionally 
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 placed 
the pots of plants in regular order, the tallest behind, and the lowest
