quire - no more light •, therefore thefe glafies fnould 
not be longer than is abfolutely neceffary, which will 
render them more manageable ; but the annexed plan 
will render this more intelligible, than any written de- 
fcription can do. 
The other fort of Stove, which is defigned for railing 
of young plants until they are of a proper fize to 
produce fruit, need not be built fo high as the former, 
therefore there will not be wanting any upright glalfes 
in the front ; but the frames may be made in one 
flope, as in the annexed plan : indeed of late years, 
many perfons have made tan-beds with two flues run- 
ning through the back wall to warm the air in win- 
ter •, and thefe beds have been covered with glafies, 
made in the fame manner as thofe for common hot- 
beds, but larger ; thefe were contrived to lave expence, 
and have in many places anfwered the intention, but 
to thefe there are leveral objedtions. i. That of hav- 
ing no paflage into them, fo that the glafies mull be 
taken off when the plants want water, &c. 2. The 
damps very often rife in the winter feafon, when the 
glafies are clolely fhut, which often prove very in- 
jurious to the plants. 3. There is danger of the tan 
taking fire, where there is not great care taken that 
it doth not lie near the flues ; fo that although the 
fmall Stoves here propofed require more expence in 
their building, yet, being greatly preferable to thofe 
pits, and the after expence being the fame, they will 
be found fo much more convenient as to render them 
more general where this fruit is cultivated. 
Where there is no danger of the wet fettling about the 
tan in winter, the bark-pit may be funk two feet deep 
in the ground, and raked one foot above the furface ; 
the only walk which is neceffary in thefe Stoves, is that 
on the back of the tan-bed, which may be on the level 
with the furface of the ground, fo that the tan-bed 
will be more than one foot above the walk ; and the 
flues beginning from the level of the walk, there will 
be room to return them three times, which will warm 
the air much more with the fame fire than when they 
are carried but twice the length of the Stove. 
But ih wet land the tan-bed fhould be wholly raifed 
above the level of the ground, in order to preferve the 
tan from being chilled by moifture •, and in fuch 
places the walk on the back fhould be railed near two 
feet above the level of the ground, becaule the tan- 
bed fhould not rife much more than one foot above 
the walk ; for if it is higher, it will be more difficult 
to reach the plants when they require water ; the brick 
wall of the pit, on the fide next the walk, need not be 
more than four inches thick, fo far as rifes above the 
Walk* but below that it fhould be nine inches thick ; 
the reafon for reducing the wall above, is to gain 
room for the walk, which would otherwife be too much 
contradted •, and if there is a kirb of Oak laid on the 
top of the four inch wall, it will fecure the bricks 
from being difplaced, and iufficiently ftrengthen the 
wall, which being but one foot above the walk, 
will not be in any danger of falling •, and on this kirb 
there may be two or three upright iron bars fixed with 
claws, to fupport the crown-piece of timber, which 
will fecure it from hanging in the middle, which in 
a great length is very often the cafe, where there 
are no fupports placed under it : there may be more 
or lefs of thefe bars, according to the length of the 
Stove ; but if they are about ten feet afunder, it 
will be near enough. If thefe iron bars are one inch 
fquare, they will be ftrong enough to anfwer the 
defign. 
But as it is hoped that the annexed plan of this fmall 
Stove will= convey a clear idea of the whole contri- 
vance, this will render it unneceffary to add any far- 
ther defcription here. 
An Explanation of the Plate which reprefents the two 
forts of frames with oiled paper for covering of 
Melons. 
The firft of thefe frames is contrived like the covers 
of waggons ; it has a frame of wood at the bafe, to 
which are fattened broad hoops which are bent over 
circularly, as is reprefented at fig. 1. The width of 
this frame fhould be from five to fix feet, for lefs than 
five feet will not be fufficient to cover the bed, and if 
they are more than fix feet broad, they will be too 
heavy and troublefome to move, a fhews the febtion 
of the width, b the frame of wood at the bafe, c the 
arch of hoops, and d a fmall flip of wood which is 
fattened to the under fide of the hoops to keep them 
in their proper pofition. - 
The diftance between each hoop fhould not be more 
than one foot, and there fhould be two rows of 
ltrong packthread or rope-yarn on each fide of the 
arch running from hoop to hoop at the places marked 
e. e. e. e. to keep the oiled paper from finking down 
with wet. The length of each frame fhould not be 
much more than ten feet, which will be fufficient 
length for covering three plants, that being about the 
fize of a three light frame, for if they are longer they 
will be heavy and troublefome to move ; therefore 
there fhould be as many of thefe frames made, as may 
be neceffary for covering the quantity of plants de- 
fired. Fig. 2. reprefents two lengths of thefe frames 
joined ; G. fhews the profile of the frame, and H. re- 
prefents the paper turned back, that it may be feen 
how it is laid over the frame, 
Fig. 3. reprefents the other fort of frame which is 
contrived like the roof of a houfe, a fhews a fedtion 
of the bafe •, b b the two flopes, c one of the fides 
which is contrived to be raifed at any time to admit 
air to the plants ; d fhews the place where this fhuts 
down, and e the prop which fupports it. If in the mak- 
ing of thefe frames every other light is made with 
hinges fb as to be raifed, and on the oppofite fide they 
are contrived to rife alternately, jt will be a very good 
method, for then air may be given at the fide contrary 
to the wind ; and in very warm weather, when the 
plants require a large fhare of air, they may all be 
raifed on both fides, which will make a thorough air 
to the whole bed. Fig. 4. fhews the plan of thefe 
frames, and fig. 5. the fame erebled g reprefents 
the profile of it, and / the covering of paper. This 
fort of frame may be made of pantile laths, or of flips 
of deal of like dimenfions, becaufe they fhould not 
be too heavy •, but the bafe of the frame to which 
thefe are fattened, fhould be more fubftantial. Some 
perfons who have made trial of both, recommend the 
latter for the convenience of giving air to the plants, 
for there is no other contrivance in the firft fort for 
admitting the air, but by raifing the whole frame on 
one fide in proportion to the quantity of air intended 
to be admitted ; and when the feafon is warm they 
generally raiie thofe frames on both fides, and per- 
mit the plants to run out from under them. 
When tliele frames are made, if they are well painted 
over with the following compofition, it will greatly 
preferve them, viz. to every fix pounds of melted 
pitch, add half a pint of Lintfeed-oil, and a pound of 
brick-duft ; thefe fhould be well mixed together, and 
ufed warm when this dries it becomes a hard ce- 
ment, fo that no moifture can penetrate through it, 
and is the belt fort of pigment for all timber expofed 
to the weather, I have ever feen ufed ; fo that where 
the colour is not offenfive to the fight, it fhould be 
preferred to every other. 
When the frames are thoroughly dry, the paper 
fhould be patted on to the frames. The beft fort of 
paper for this purpofe is what they call Dutch wrap- 
per •, this is ftrong, and when oiled over becomes pel- 
lucid, fo admits the rays of light through it extremely 
well. After the pafte is well dried, the paper fhould 
be oiled over on the outfide, which if well done with 
Lintfeed-oil will be fufficient, for the oil will foak 
quite through the paper, fo there will be no necefiity 
for oiling both fides, nor for doing it over more than 
once. The oil fhould be dry before the frames are 
expofed to the w:et, otherwife the paper will tear. In 
the patting of the paper on the frames, there fhould 
be care taken to ftretch it very fmooth, and alfo to 
pafte it to all the ribs of the frames, and alfo to the
