Jan.] THE FRUIT GARDEN. 39 
heat frame, six or eight feet high behind, and one in front, the ends 
conformable, and sloping frames of glass-work raised from the 
front, sloping either quite to the top of the back-wall, or to incline 
only about one half towards that part, meeting a covered roof at top, 
half way, which should be raised high enough in front to throw the 
water off behind, as well as to admit as much sun as possible to 
every part of the frame; or it may be constructed with an upright 
front of glass, head high, and a sloping roof of glass work, ranging 
from the upright front to the top of the back wall, which is rather 
the most eligible form, both for convenience and benefit of the 
plants; either of which constructions may be erected detached, or 
against a south wall already built, which will serve for the back, 
and save some expense; the ends may either be of wood or brick, 
and the glass-work in every part should be made to move on and off, 
as well as to slide backward and forward to give air, and to do other 
necessary work; and at one end, near the back wall, may be a door 
to enter occasionally; and within-side must be a pit for the bark- 
bed, three feet deep, part sunk, and the greater part raised, conti- 
nued the whole length and width, except about a foot and half alley 
to go in to perform the necessary culture, as well as to view and 
gather the produce of the different plants. 
The pit within is to be filled with new tan any time in winter or 
spring, you intend to begin forcing, though January is soon enough, 
and the beginning of February is not to late; the bark will support 
a growing heat three months, and if then stirred up to the bottom, 
will renew its heat, and continue it two months longer. 
In this frame may plunge in the bark-bed pots of roses, or any 
other choice flowering shrubs you would force into an early bloom; 
likewise may place pots of strawberries towards the front and top 
glasses; and pots of kidney-beans and early dwarf peas may be placed 
in any part of the frame; also pots of dwarf fruit-trees, before men- 
tioned, pots of double pinks, carnations, and any other moderate- 
growing fibrous-rooted perennials, as well as any sorts of bul- 
bous or tuberous-rooted flowers, as narcissuses, jonquils, tulips, 
anemones, ranunculuses, hyacinths, and various other sorts. 
The heat of the bark-bed will effectually warm the earth and in- 
ternal air sufficiently to forward any sorts of hardy flowers and 
fruits to perfection at an early season; observing, that, although 
they do not always flower and fruit so abundantly as in the full 
ground, yet, if there are but a few of any sort, a month or two before 
their natural season, they, if for sale, will sufficiently pay; and if 
for private use, they will always be acceptable as a rarity and cu- 
riosity in the family. 
Fresh air must be admitted in fine sunny days at all opportuni- 
ties, by sliding some of the glasses more or less open, keeping 
them close at night; and in very severe weather, the glasses must 
be covered with mats, or closed with sliding shutters made for that 
purpose, particularly at night; which trouble might be avoided if 
there was a fire-flue, by which heat could be introduced to counter- 
act the extreme rigour of the frost, when necessity required. 
When the heat of the bark declines considerably, do not omit
