thereon above a fortnight in autumn* and about the 
fame time in fpring, and during the other parts of 
the year they will fall obliquely thereon * and in fum- 
mer, when the fun is high, the rays will not reach 
above five or fix feet from the glaffes, for the proof 
of this fee the article Sun. Befides, the plants placed 
toward the back part of the houfe, will not thrive in 
the furnmer feafon for want of air * whereas when 
there are hoping glaffes at the top, which run within 
four feet of the back of the houfe, thele, by being 
drawn down in hot weather, will let in perpendicular 
air to all the plants * and of how much ferviee this is 
to all forts of plants, every one who has had oppor- 
tunity of obferving the growth of plants in a Stove, 
will eafily judge * for when plants are placed under 
cover of a deling, they always turn themlelves toward 
the air and light, and thereby grow crooked * and if 
in order to prelerve them ftrait, they are turned every 
week, they will neverthelefs grow weak, and look 
pale and fickly •, for which reafons, I am fure, who- 
ever has made trial of both forts of Stoves, will rea- 
dily join with me to recommend the model of the 
bark Stove for every purpofe. 
As to the farther contrivance of this Stove, it will be 
neceflary to obferve the temper of the place, whether 
the fituation be dry or w T et * if it be dry, then the 
floor need not be raifed above two feet above the le- 
vel of the ground ; but if it be wet, it will be proper 
to raile it three feet, efpecially if thefe flues are to 
be carried under the floor* for when they are ere&ed 
clofe upon the furface of the ground, thefe will raife 
a damp, which will prevent the flues drawing fo well 
as when they are more elevated. The furnace of this 
Stove muft be placed at one end of the houfe, ac- 
cording to the directions before given. This muft be 
made according to the fuel intended to burn, which, 
if for coals or wood, may be made according to the 
common method for coppers, but only much larger * 
becaufe, as the fire is to be continued in the night 
chiefly, if there is not room to contain a proper quan- 
tity of fuel, it will occafion a great deal of trouble 
in attending upon the fire in the night, which fhould 
be avoided as much as pofiible * becaufe, whenever the 
trouble is made very great or difficult, and the per- 
fon who is intrufted with the care of it, has not a 
very great affeftion for the thing, and is withal not 
very careful, there will be great hazard of the fire 
being neglefted, which in a little time may be of 
dangerous confequence to the plants * but, if the 
fuel intended be turf, then the contrivance of the 
furnace may be the fame as for the bark Stove already 
mentioned. The flues of this Stove, if they are car- 
ried under the pavement, may be turned after the fol- 
lowing manner. 
which will caufe them to draw better than if ftrait, and 
by this method of difpofing them, they may be fo much 
ruined as to leach almoft from the back to the front 
of the houfe. 
q he depth or them fhould not be lefs than eighteen 
inches, and the width nearly equal, which wifi pre- 
vent their being choaked up with foot, as is often the 
cafe when the flues are made too fmall. The fpaces 
between the flues fhould be filled up either with dry 
brick rubbifli, lime, or fand, from which there will 
little moifture arife * and the flues fhould be clofely 
plaiftered with loam both within and without, and the 
upper part of them covered with a coarfe cloth under 
the floor, to prevent the fmoke from gettino- into the 
When the flue is carried from the furnace to the end 
of the houfe, it may be returned in the back above 
the fiooi twice in flcrait lines, which may be contrived 
to appear like a ftep or two, by which means the 
fmoke will be continued in the houfe until all its heat 
is fpent, which will confequently warm the air of the 
houie the better * and the chimneys, through which 
S T O 
the fmoke is to pafs off, may be either at both ends* 
or in the middle, carried up in the thicknefs of the 
brick work of the flues, 1b as not to appear in fight 
in the houfe. The flues fhould be ftrft covered with 
broad tiles fixteen inches long, and then a bed of 
fand laid over them about two inches thick, upon 
which the other tiles fhould be laid tocorrefpond with 
the reft of the floor. This thicknefs of cover will be 
full enough to prevent the too hidden rife of the heat 
from the flues. 
But if the furnace is placed under the floor, the thick- 
nefs of fand between the brick arch which covers it 
and the floor, fhould not be lefs than four or fix inches, 
fo that the bottom of the furnace fhould be funk the 
lower * and if from the fire-place to the end of the 
houfe, the flues are laid a little rifling, it will caufe 
them to draw the better 5 but this rife muft be allow- 
ed in the placing them lower under the floor next the 
fire, becaufe the floor muft be laid perfe&ly level, 
otherWife it will appear unfightly. 
In this Stove there fhould be a ftand or 
fcaffold erected for placing fhelves above 
each other, in the manner annexed, that 
the plants may be difpofed above each 
other, fo as to make a handfome appearance in the 
houfe * but thefe fhelves fhould be made moveable, 
fo as to be raifed or funk, according to the various 
heights of the plants, otherwife it will be very trou- 
blefome to raife or fink every particular plant kccord- 
ing to their heights, or every year as they advance in 
their growth. 
In placing the feet of this ftand you muft be careful 
not to fet them too near the fire, nor diretftly upon 
the top of the flue* efpecially that end next the fire, 
left by the conftant heat of the tiles the wood fhould 
take fire, which cannot be too much guarded againft ; 
fince fuch an accident would go near to deftroy all the 
plants, if the houfe efcaped being burnt. This ftand 
or fcaffold fhould be placed in the middle of the houfe, 
leaving a paffage about two feet and a half in the 
front, and another of the fame width in the back, for 
the more conveniently palling round the plants to wa- 
ter them, and that the air may freely circulate about 
them. In difpofing the plants, the talleft fhould be 
placed backward, and the fmalleft in front, fo that 
there will not be occafion for more than five or fix 
fhelves in height at moft * but the fcaffold fhould 
be fo contrived, that there may be two fhelves in 
breadth laid upon every rife whenever there may be 
occafion for it, which will fave a deal of trouble in 
difpofing of the plants. 
In the eredion of thefe Stoves, it will be of great fer- 
vice to join them all together with only glafs partitions 
between them, as was before obferved : and where 
feveral of thefe Stoves and green-houfes are required 
in one garden, then it will be very proper to have the 
green-houfe in the middle, and the Stoves at each end, 
either in the manner direded in the plan of the green- 
houfe exhibited in that article, or carried on in one 
ftrait front. 
By this contrivance in the ftrudure of thefe houfes, a 
perfon may pafs from one to the other of them, 
without going into the open air * which, befides the 
pleafure to the owner, is alfo of great ufe, becaufe 
there will be no occafion of making a back-way into 
each of them, which otherwife muft be, fince the 
front glaffes of the Stove fhould not be opened in cold 
weather, if it can poflibly be avoided on any account, 
otherwife the cold air rufhing in, will greatly prejudice 
the very tender plants. 
But befides the Stoves here defcribed, and the green- 
houfe, it will be very neceflary to have a glafs-cafe or 
two, wherever there are great colledion of plants, 
i hefe may be built exactly in the manner already de- 
fcribed for the Stoves, with upright glaffes in front, 
and doping glaffes over the top of them, which 
fhould run within four feet of the back of the houfe. 
The height, depth, and other dimenfions, fhould be 
conformable to that of the Stoves, which Will make a 
regularity in the building. Thefe may be placed at
