The next Caution concerns the Bark- beds : the | 
Dimenfions and Place of th efe we have given, 
‘and at one End they wilt each of them come 
towards the Fuire-place: 
ger is to be apprehended from this, and no 
Care is too much to prevent it: if the Fire 
have too much Power upon the Bark, it will 
at once prevent all its good Effects, which 
are the Moxtture and the Fermentation: the 
Bark-Stove will thus be brought | into. the 
Condition of a.dry one: and 
it will probably foon be worfe than thi§: the 
~ Bark, when thoroughly dry, may take Fire ; 
‘and every thing be deftroyed at once. 
The Gardener underftands that between the 
Brick-work of the Fire-place, and the Wall 
of the Pit, there is a Space anfwerable to the 
Walk behind, it may be dug out and left 
entirely hollow ; turning an Arch over it for the 
Support of that Walk. This is the moft 
fecure Method; for the Heat will continue 
itfelf in a ad Aree Manner through folid 
Subftances. 
The Glaffes in Front being moveable, may 
ferve very well for the Entrance, at fuch Times. 
as it may be proper to open them; but in 
cold Seafons they muft be kept fhut; and 
there muft be an Entrance into the Stove made | 
in fuch Manner, that the Gardener can go in 
without admitting much cold Air after him: for 
this Purpofe the Entranee muft either be thro’ 
fome fheltered Place, or very well defended 
- by a double Door; but the firft Way of coming 
into the Stove from another Room, and not 
immediately out of the open Air, is vaftly 
preferable. 
If there be thofe Glafs Buildings at each 
End which we have juft defcribed, the Way

vantages of its particular Structure loft.. But 
does not follow here from Choice.

wha 
will be wcciak them; and ‘as the Air in 
thofe Buildings is avails much warmer than . 
without; there will need no more than the 
coer. Form of a Door to the Stove. 
If there be not this. Convenience, it will be 
beft to open two Doors into the Stove, one 
from each of the Sheds where the Fireplaces 
are. As the Flues run on one Side, the Door 
fhould be made on the other; and the Air 
being always warm in thefe Sheds by the 
eke there will be: no Danger -of chilling the 
Plants. 
With ne to the Fuel shine fous be ufed, 
the moft familiar,. natural, and ready,. is com- 
mon Sea-coal.. And the fmaller Kind fhould. be 
-chofen, becaufe that will make the moft uniform 
Heat. 
In Holland they ufe Turf, becaufe it is the 
common Produce of. the Country; and in 
France they have chofen Wood for the fame 
Reafon: let the Gardener take Care that what 
is the Effect of Neceffity in thefe Places he 
With us 
Coal is not only the readieft at Hand, but 
the eafieft managed, and it has the Advan- 
tage of making lefs Soot than either of the 
other Kinds; and of heating the Air more 
uniformly. 
The two or three lower Flues only, in Places 
where Wood or Turf are burnt, have any 
confiderable Heat, and the Air is therefore 
warmed irregularly: but in the Ufe of Coal, | 
thefe Flues being carried up fo high, ‘the Air 
| is warmed regularly all the Way up them, 
and confequently all up the Houfe. 
The principal Quantity of Smoke that is 
made by this Fuel, lodges its Soot in the firft 
Flue; and we have directed that to be made 
fo wide, that it is eafily cleaned.

Of the filling the PITS. 
Fter the Defcription we have given of the 
feveral Parts of the Bark-Stove, the Gar- 
dener will perfectly well underftand its Na- 
ture. 
He knows that the Pits were opened for 
Tanner’s Bark; which, in fuch a Body as 
they are capable of containing, will ferment, 
and retain a ufeful Heat and Moifture a long 
Time. 
The Pots, containing the Plants, are to be 
fet in this up to the Rim; and fome, which 
will better bear a dry Heat, on the level Top 
of the Flues. 
We have explained the Nature and Benefit of 
Tanner’s Bark ina preceding Part of this Work, 
and the Reader will therefore in fewer Words

Let it be of a middling Size or 
rather inclining to large; and, with every Load 
of it mix a Buthel ee Elm Sawdutt. Throw 
the whole Quantity up into a Heap, and let 
it lie thus for the Water to run off, and for 
the Beginning of the Fermentation. 
When it has lain a Week, let it be 
thrown into the two Pits by a little at a 
Time, and fpread with Care: this Motion, - 
Let a Quantity of Bark,

| which will for the prefent check the Fermen- 
tation, will bring on, foon after, another, and 
this will come on gradually ; and the Quantity 
being great in each Pit, it will laft a grear 
while. Six Months the Heat of this farft laid 
Quantity will very well continue; and when
