ON THE MANAGEMENT 
I have already obferved that the floor has a fall or defcent 
of fix or eight inches, inclining to the South ; and here I would 
recommend, that the furface of the ground upon it fbould, 
when finiflied, be reverfed, that is, that the part at fome 
diflance from the Hot-houfe ihould be raifed five or fix inches 
above the level of the ground immediately adjoining the ftove. 
The ground at each end fhould alfo be brought to the fame 
height. In fhort, the furface of the whole fliould have an 
eafy fall of two or three inches to a certain point, where a 
grate fhould be fixed, to take off the water that falls from the 
roof of the Hot-houfe. About the middle of the front wail 
will be the moft convenient place for this purpofe, as the 
ground at each end may be raifed to have an eafy fall into it. 
The grate muft be laid in a groove cut two inches deep in a 
fmooth flione; and a fecond groove, one inch and ahalf deep muff 
be cut round the former. The intent of this latter groove is to 
receive a board, which mufi: be made to go in and fit very clofe, 
fo as to afford an opportunity of floating the ground in front 
occafionally : But of this I fliall have occafion to fpeak more 
at large hereafter. The ftone I here fpeak of mufi; be laid im- 
mediately over the drain, adjoining the front wall of the fiove, 
and raifed about two feet three inches above the top of the 
faid drain. The ground, including a thin coat of gravel, of 
about two inches thick, mufi be laid perfedily even with the 
top of the fione, vrhich is the central point for drawing off the 
water from the furface of the whole.
