Oct.] THE HOT-HOUSE. 551 
out of it, also the younger successions in the next advancing stage, 
should be placed in the pits, frames, or other winter departments. 
All these will now require to be renewed with a proper quanti- 
ty of new tan, one half at least, so as to support a regular heat for 
a considerable time, the whole of the old tan must be sifted, and 
what goes through che screen, may be used for covering beds where- 
in are planted bulbous roots, &c. to protect them from frost: as 
much new tan previously made sufficiently dry, must be added to 
the coarse part, as will fill up the pits again a little above the top, 
mixing both well together as you proceed in the filling, This done 
plunge the pots as directed on other occasions. 
General Care. 
The pines and all the other exotics, must have regular care and 
attendance; let water be given once or twice a week to some, oftener 
to others, as you see necessary, being careful not to give too much 
at a time, for that would not only injure many plants, but destroy 
the heat of the bark -bed. 
Admit fresh air into the house every calm, or warm day, espe- 
cially when the sun shines, by sliding open some of the glasses from 
nine or ten o'clock, till two, three or four, always observing to 
close the house in the afternoon while the air is warm, to super- 
cede the necessity of fire, as long as possible; and if you must have 
recourse to it, towards the latter end of the months use it but mo- 
derately at this season. 
The advantages of keeping the house as cool as may be consis- 
tent with the safety of the plants, during this and the next month, 
are'very obvious; all the plants are gradually hardened and rendered 
thereby capable of bearing the vicissitudes of the winter season, bet- 
ter than if they were drawn up tender and weakly by too much 
heat; but the pines in particular, if forced at this season, would, 
many of them, start to fruit at an untimely period, which would 
get stunted and misshapen before the commencement of the free 
spring vegetation, and would consequently be totally lost, or not 
worth their room in the house. 
When the leaves of any plants decay, they should be picked off", 
and the house kept 'constantly clear from fallen leaves, cobwebs, or 
any other filth; which not only renders the house neat, but is very 
necessary to preserve the plants in health. 
Wintering Hot-House plants in Garden-Frames. 
There are few tropical plants but may be preserved during win- 
ter, while in a small state, in garden-frames well constructed and 
attended; so that an ingenious and careful gardener may not despair 
of preserving the most rare plants in winter, without the aid of a 
Hot-House; and even where there is one, and the stock of plants 
too numerous, such auxiliary convenience will be found of conside- 
rable utility.
