‘Sept. and on this he is to depend perfectly and entirely 
—— for the preferving it in the fame State. For this 
Purpofe let him procure two perfectly good Ther- 
mometers, and let him take Care that they are 
continually in right Order. 
f» Let them be placed one in each Divifion “of 
“the Stove ; and.at a Diftance from the Fire-place, 
for they ate to fhew the general Temper of the 
Air in the Room, and they muft not be within 
the Reach of the Fire to be any other way af- 
fected. 
The Contrivance of thefe Machines is now re- 
duced to fuch Exaétnefs and Certainty, that no- 
thing is left to the Judgment of the Gardener ; 
but he is to do every Thing by Obfervation: the 
- Degrees are marked; and all he is.to obferve is, 
that he by no means let it rife or fall much below 
the true Place. | 
A little warmer in the one Divifion of the 
Stove, and a little lower in the other, will be. 
proper for the fuiting the Condition of the Air to. 
the different Degrees of Tendernefs in the Plants ; 
and it is not to be expected, that this can be 
exa@tly kept to the Mark at all Times. 
It would difcourage the Gardener from doing 
his Duty, to tell him fo much more than could be 
_ perform’d, was expected of him. All that he 
needs to da is this: let him obferve by the 
Thermometer, what is the exaét and proper De- 
gree of Heat for each Divifion; and: let him

actly at that Point; nor will there be any Da- 
mage to the Plants in its beifig fometimes two 
or three Degrees below, or fometimes two or 
three’ Degrees above it. 
This gives the Gardener a Latitude of fix De- 
grees: within this there will be no Danger, but 
within it he muft abfolutely keep. If he go often 
into the Stove, he will be in no Danger of keep- 
ing it within this fair Compafs; but Neglect of 
vifiting the Place. may run him into the moft —  ~ 
deftructive Errors. | 
It. is equally dangerous to the Plants, to be 
kept in an Air a great deal too warm, or a great 
deal too cold: but the Change is fo eafily made, 
as the Heat depends upon actual Fire, that there 
is no Danger of lofing any of them this Way; 
except by ie efolute Neglect of looking in at 
different Times in the Day. 
The Afpect of thé Plants will thew prefently

Condition, or appear lively, unlefs the Heat be

VY his Plants in a perfectly right Condi-

Therefore let the Gardener know what he will

frefh Quantity of Bark equal to about one-fourth 
of the original Quantity. 
When this is ready, let him take out the ren 
and pare off as much of the Bark at the Surface, - 
as the new Quantity will fupply: this being re-

with a three-prong’d Fork dig up and turn the
