annuals, and other rare plants. You maj 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 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 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 beauty 
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 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
