Nov.] THE GREEN-HOUSE. 573 
and in wet or frosty weather: even in very severe weather, 
you may happen to find an hour or two in the middle of the day in 
which to slide down the upper lights, to admit fresh air, and suffer 
the foul to pass out; this may be often done when it would be quite 
imprudent to raise the lower sashes. But if a very rigorous frost 
should set in towards the latter end of the month, it may be neces- 
sary to make a fire in the evening, to prevent its penetrating into 
the house; however, this should not be resorted to while you can, 
keep out the frost by means of good shutters or by fastening mats in 
front of the windows at night; for too much heat at any time, but 
particularly in the early part of the season, is of serious injury to 
the green-house plants, which require nothing more than merely to 
be kept from frost. 
Occasional, but gentle waterings, must now be given to all the 
plants; some will require to be watered three times a week, while 
others, particularly the succulent kinds, will not need it more than 
a little once a week; but as the state of the weather sometimes 
makes a very material ditt'erence in this, there is no saying how 
often, or how much at a time, ought to be administered; however 
it will be safer to give a little and often, than too much at a time, 
which should now be administered in the forenoon of fine days, that 
the damp may pass oft' before the windows are shut, lest the steam 
occasioned tliereby might create a mouldiness, and injure the plants. 
Pick off all decayed leaves from the plants, and throw them out 
of the house; for if they are sui!ered to remain in it, they will rot 
and infect the air, which foul efiiuvia being imbibed by the plants, 
will infect them also, and bring on disease and vermin. 
Examine the tubs and pots occasionally, and if the earth cakes or 
binds at top, loosen it to a moderate depth; and where decayed 
branches or shoots occur, prune them off as soon as observed, and 
cast them out of the house. 
The myrtles and other plants which are in frames, or pits, must 
now be duly attended to, in like manner as those in the green-house. 
The frames or pits, to the full height of the glasses, must be lined 
around with horse-dung, leaves, straw, fern or the like, to keep the 
frost from penetrating in at the sides and ends; the plants must have 
plenty of fresh air at all favourable opportunities, and be effectually 
protected at night and in frosty weather, by laying a sufficient 
covering of mats, straw, boards, &c. over the glasses, observing not 
to deprive them of the benefit of light but while absolute necessity 
requires it. 
Preserving tender Bulbs, ^-c. 
As some persons who have not the convenience of a hot-house 
may be desirous of having some tender exotic bulbous and tuberous 
rooted plants, such as crinums, pancratiums, arums, amomum 
zingiber, or true ginger, &c. These and such like roots may, in the 
beginning of this month, be taken up and carefully dried as you do 
tuberoses, and then packed up in very dry sand, or in extremely 
dry moss, observing to keep them during winter completely out of
