104 THE HOT-HOUSE. [Jan. 
and take care that they are not made too strong, for that would 
be of very bad consequence^ and to avoid this, have a thermometer 
placed in the hot-house, as a direction to regulate the degree of 
heat. 
Water should be given to the pine-apple plants once a week, or so 
often as it may seem necessary, and always very moderately; and 
let as little as possible fall into the heart or between the leaves at 
this season. 
For the conveniency of watering the pines and other plants that 
are plunged in the bark-bed, a long pipe, made of tin, would be 
eligible to use occasionally; this should be in three different joints, 
in order that it may be shortened or lengthened as you see it con- 
venient: one of these joints should have a funnel made at the 
largest end, that by pouring the water out of a handy watering-pot 
into the funnel, the water is conveyed to the pots in any part of the 
bed with greater exactness, without pouring it into the heart of the 
plants. 
All other tender exotic plants in the hot-house or stove should be 
supplied with water as they require it. 
The woody kinds will require it often, those of the succulent 
tribe but seldom; or at least but very little must be given them at 
a time. 
Be sure to have soft water for watering the different sorts of 
plants, for which purpose you may have a tub or cistern in some 
convenient part of the house to contain it, in which it is to remain 
till the cold chill is completely off. 
In the management of the plants in the bark-bed there must be a 
particular regard had to the temperature of the bark and the air of 
the house, that neither be too violent, as also to water them fre- 
quently but sparingly, especially the shrubby kinds, because, when 
they are in a continual warmth, which will cause them to perspire 
freely, if they have not a proper supply to answer their discharge, 
their leaves will decay and soon fall off. 
In very severe weather, when necessity requires strong fires to 
be kept up for any length of time, and that the internal air becomes 
thereby of a dry and parching nature, it will be well to sprinkle the 
flues occasionally with water, to raise a comforting steam in the 
house, and to restore the air to its true atmospheric quality, which 
is always most congenial to the health of plants. 
Every plant in the hot-house or stove should be kept perfectly 
clean from dust or any sort of foulness; if any thing of that nature 
appears on their leaves, let the large-leaved sorts be washed with 
a sponge, &c. the others by occasionally watering them all over the 
top. 
Kidney -beans raised in tke Hot-house. 
Those who have the conveniency of a hot-house may raise early 
kidney-beans with little trouble. The early cream-coloured dwarf, 
speckled-dwarf, and yellow-dwarf, are proper sorts for this pur- 
pose.
