100 THE HOT-HOUSE. [Jan! 
beautiful than they otherwise would, where they gradually inured to 
the open air in the hot-house before their being brought out, by 
occasionally sliding open the roof as well as the front glasses, and 
never letting the heat arise in the house to too high a degree. 
Those destined to remain in the bark-bed during summer, such as 
the pine-apple, &c. are still worse off; for, if the root is kept on, 
they are rendered good for nothing, and if taken totally off, both 
them and the bark-bed are exposed to heavy rains, which destroy 
the heat of the one, and consequently injures the health, vigour, and 
fruit of the other: therefore all stoves ought to be constructed with 
sliding roof as well as front lights. 
Nursery and Succession Stoves. 
Besides the main bark stove already described, it is very con- 
venient to have one or two smaller, such as a nursery-pit and a 
succession stove, particularly where there are large collections, 
and more especially in the culture of pine apples; one serving as a 
nursery-pit, in which to strike and nurse the young offspring 
crowns, and suckers of the old pines for propagation; the other as 
a succession-house for receiving the year old plants from the 
nursery-pit, and forwarding them a year to a proper size for fruit- 
ing as succession plants, to furnish the main stove or fruiting- 
house every autumn, to succeed the old plants then done fruiting. 
These smaller stove departments prove materially useful in the 
culture of pines, particularly to raise and nurse the young plants, 
until arrived to a proper age and size to produce fruit, then moved 
into the main stove or fruiting-house, which being thus supplied 
from these smaller stoves, with a succession of fruiting plants 
annually, without being crowded or incommoded with the rearing 
of the said succession plants, proves a particular advantage, not only 
in the culture of the fruiting plants, as they often require a higher 
degree of heat than the succession plants at particular times, in 
order to forward and improve the growth of their fruit, but it is also 
making the best advantage of this main department, to have the 
bark bed instantly filled with fruiting plants only, producing a 
full crop of proper sized pine apples every year, which could not 
always be effected with such certainty and perfection without the 
aid of these succession stoves, because the pine plants in their 
infant state require sometimes different management from the 
fruiting plants, particularly in respect to the degree of fire-heat, 
which, in general, should be more moderate than for the fruiting 
plants, lest too much should force them into fruit in their minor 
growth, when incapable of producing such in any tolerable per- 
fection. 
Therefore, these smaller succession stoves may be erected as 
appendages to the main house, or may be detached at some little 
distances, as may be convenient; though if the situation admits, 
it may be both more convenient and ornamental to join them in a 
line with the main stove, one at each end, and nearly of the same 
construction, but smaller both in length, width, and height, if
