glasses; the same stove serving to force fruits, flowers, 8cc. as before 
observed. 
Such stoves as are intended principally for pine-apples, and for 
forcing flowers, strawberries, and some sorts ot culinary esculents, 
&c. may be only ten or twelve feet high behind, which generally 
answers better for such than those of more lofty dimensions; or by 
raising the bark-pit within wholly above the surface, and sinking 
the front walk about afoot, the roof may be lower, and such plants 
by that means, be brought nearer to the glass, which proves ex- 
tremely advantageous to their growth. 
When stoves are erected for cultivating and bringing to the 
greatest possible perfection the taller kinds of exotics, they are 
made from sixteen to twenty, or even to twenty-five feet high in 
the back wall, with width in proportion, by only six feet height in 
the front glasses, in order to suit low as well as high plants; and 
with the roof sloping quite from the top of the back wall to the 
front, and wholly of glass-work, having a capacious bark-pit within, 
formed towards the front; behind which is sometimes a pit of 
earth, either on a level with the bark-pit or with the back walk, to 
receive particular plants; in rear of this is a walk, between which 
and the back wall is formed a border of good earth, to receive the 
tallest-giowing plants which are intended to be cultivated. In this 
kind of stove you may cultivate exotics, 8tc. from the lowest to 
almost the highest stature, by placing those of the shortest growth, 
forward, the tallest behind, and so on according to their several 
gradations of height. 
However, these very lofty and capacious stoves are not recom- 
mended for general use, they being both very expensive in erect- 
ing, and in the consumption of a great quantity of fuel; and not so 
well calculated for the growth of the general run of exotics, as 
stoves of a moderate height. 
Flues ought not to be erected along the back walls, in such stoves 
as have plants trained thereto or growing immediately close to 
them; and one range round the front and ends will not be sufficient 
to keep up a due warmth in such large houses in severe weather, 
without consuming an immense quantity of fuel; and at times rais- 
ing a scorching heat in the parts of the house next to this single 
range, by overheating it in order to force through it a heat suffi- 
cient to keep the entire of the house warm; this can never protect 
and promote the growth and health of plants so well as that gradual 
glow of moderate warmth issuing from flues of several returns, 
carried under the walks, or other convenient places, as well as 
round the front and end walls; either in double or single ranges, and 
especially under the back walk: over which broad planks may be laid, 
resting on loose bricks, for the convenience of walking during the 
winter season; from these the heat will be equally diffused through 
the whole house, and to produce which, half the fuel will not be 
necessary that must be consumed in keeping the house warm by a 
single range round the front and ends only. 
In the erection of stoves it will not be necessary to have the ends
