550 THE HOT-HOUSE. [Oct, 
The plants are to have light and air given to them at every fa- 
vourable opportunity, and should be treated, generally, as directed 
for those in the Green-House. 
Many other similar contrivances may be made, and with the de- 
sired effect, as nothing more is necessary for the preservation of 
these plants, than light, air, a moderate share of moisture, and an 
effectual protection from the frost. 
THE HOT -HOUSE. 
Pine-Apples. 
In the early part of this month, the pine plants that are to 
produce fruit next season, should be removed out of the nursery- 
stove, &c. into the fruiting-house; but previous to this, you 
should take out of the pit all the old bark, and fill it with new, fresh 
tan, previously prepared as directed last month, page 509: ob- 
serve not to put it into the pit in too wet a state, for in that case it 
would be a long time before it would come to a kindly heat, and 
sometimes not at all, so as to answer the end. 
Some people sift the old bark, and use the coarse part with 
new, about one half of each; but if you can conveniently procure 
a sufficiency of new tan to fill the pit entirely, it will answer much 
better for this purpose. 
When the bed begins to heat and that the warmth has reached 
the surface, bring in your fruiting plants and plunge them in the 
bark bed to their rims; or if you are apprehensive of the new bark 
heating too violently at first, plunge the pots only half way for 
about a fortnight; if however you plunge them wholly at first, you 
must examine the bed frequently and if you find the heat at any 
time violent, then draw the pots up half way, or quite out of the 
tan as you see convenient, to prevent its burning the roots of the 
plants, and plunge them again as soon as it can be done with safety. 
The plants thus finally placed in the fruiting house, are to get 
the usual and necessary attendance; air must be admitted every 
mild and warm day, and gentle waterings given when necessary. 
Towards the latter end of the month, the nights will be grow- 
ing very cold, and sometimes it may be found necessary to kin- 
dle a small fire in the evening; but you should never resort to 
this, while the heat of the house keeps up at night to 52° of Fah- 
renheit, which will generally be the case during the whole of this 
month if you take care to shut the house in the afternoon when 
pretty warm; but should cold, cloudy weather, continue for a few 
days, it may render a little fire necessary notwithstanding. 
Succession Pines. 
The succession-house should now be replenished from the pits, 
Sec. with the pines next in growth to the fruiting plants taken
