36 THE FRUIT GARDEN. [Jan. 
rious kinds of exotic plants, may induce persons of taste, to go to 
the expense of erecting such; to whom, the following descriptions 
may not be uninteresting. 
A forcing-frame is a sort of glass-case, or light building, fronted 
with glass-frames, in which to force flowers and fruits to early per- 
fection, by aid of artificial heat, either of dung, tanner's bark, or 
actual fire. 
The general acceptation or meaning of a forcing-frame is, a fixed 
erection full to the south sun; the length may be from ten to fifty 
or one hundred feet; the width from five to fifteen, and from five 
to ten feet high; having an upright back wall, of wood or brick; 
and a front of glass work, made sometimes in one continual range 
of slope, from near the ground in front to the top of the back wall; 
and sometimes with upright glass work, head high, ranging imme- 
diately along the front, and from the top of which a glass roof is 
carried to the top of the back or main wall; either of which may be 
for general use, for the reception of various sorts of flower-plants, 
small flowering shrubs, esculents, and dwarf fruit-trees, &c. occa- 
sionally, to force into bloom or fruit, in winter, or early in spring 
and summer; whereby many sorts of the more curious flowers and 
fruits may be obtained some months before their natural season, 
which will be a great curiosity, and which is effected, as aforesaid, 
by aid of dung, bark, or fire heat; the first, (dung heat) both by ap- 
plying the dung principally against the outside of the back wall, and 
by forming it into a bed internally; the second, (bark heat) by form- 
ing it into a bed, in a pit withinside; and the third, (fire heat) by 
having several returns of flues against the inside of the back wall, 
and that of the front and both ends, for the heat to pass along; each 
of which are hereafter described: for these kind of frames are of 
different construction, according to the sorts of plants chiefly in- 
tended to be forced; and the materials of heat, as dung, bark, or 
fuel, most convenient to be obtained for forcing them; so that the 
construction of each kind of frame is separately explained. 
These frames may be employed to advantage in the vicinity of 
large towns, for forcing various plants early for market, by the as- 
sistance of which you will have for sale, in February, March 
and April, various sorts of flowers, fruits, and esculents, that 
would not in their natural state of growth have appeared till May, 
June or July. 
But, for private use, where there is a roomy pine-apple stove, it 
may also be used, occasionally, for forcing many sorts of plants, 
flowers, and some sorts of fruits, with equal success, sufficient for 
the supply of a family. 
However, where a considerable supply is required, a forcing- 
frame, distinct from the pine-stove, would be more convenient. 
In either of these departments may be introduced for forcing, 
pots of strawberries, kidney- beans, roses, honeysuckles, jasmines, 
and any other flowering shrubs; likewise carnations, pinks, sweet- 
williams, wall-flowers, stock-gilliflowers, narcissuses, jonquils, and 
early dwarf tulips, and any other desirable flower-plants or roots, 
that may be required early for curiosity; also several kinds of curious
