cultivated in it, by placing them in such different situations, as 
their na'ures may require. 
In the arrangement of the plants in this stove, some require the 
bark-bed. others succeed in any part of the house, and others, such 
as the succulent--, require the driest situation near the flues: many 
of the more tender, herbaceous, and shrubby plants, natives of 
the holiest countries, generally succeeded best when plunged in 
the bark bed, though many sorts, both herbaceous and woody, 
thrive tolerably well in any part of the Bark Stove. 
1 shall now proceed to give a minutia of its general structure, 
upoM the most miproved plan, the more especially as many persons 
who may be desirous of erecting such, may probably not be able to 
procure workmen capable of constructing it, without minute and 
particular directions. 
Having determined on the size, as to length, width, &c. proceed 
to lav the foundation of the walls, allowing due thickness for the 
erection of the surrounding inside flues on the foundation wall, with 
an allowance for iheir being detached therefrom about two or three 
inches. 
Then set off the back or north wall, at least two bricks or 
eighteen inches thick, and the front and end walls about thirteen, 
carrying up the back wall from ten to fourteen feet high, in propor- 
tion to the width of the house; but those of the front and ends, from 
two to three feet, as the circumstances hereafter noticed may re- 
quire, upon which to erect the upright timber framing for the per- 
pendicular lights; previously observing, in carrying up the walls» 
to allot a proper space for a door-way, at one or both ends towards 
the back part; setting out also the furnace or fire-place, in the bot- 
tom foundation, towards one end of the back wall behind, formed 
also of brick work, and made so as to communicate with the lowest 
flue within, the inside top of the furnace being about a foot lower 
than said flue, the better to promote the draught of heat and smoke; 
though, if the stove be more than about thirty-five feet long, a fire- 
place near each end will be necessary; or, if more convenient, they 
may both be in the middle of the back wall, each communicating 
with a separate range of flues; in either case you may form them 
wholly on the outside, or part outside, and part running through the 
wall. 
This furnace is to be made large or small according to the kind 
of fuel intended to be used, and the number of returns of the flues 
inside; for when there are but few returns, a greater quantity of fire 
will be necessary to keep a sufficient heat. If the returns are fre- 
quent, and wood is to be the fuel, the furnace is to be made only 
three feet deep, to receive wood two and a half feet long or better; 
but if the flues run only once round, with no returns, the depth must 
be five feet to receive four feet wood, especially if the house be 
large; in either case the furnace is to be made eighteen inches 
wide at bottom, the sides sloping outward to the height of twenty 
inches, where it is to be twenty-two inches wide, covered from thence 
by an arch, the top of which is to be two feet from the grate, which
