about five or fix inches thick ; or a plat¬ 
form of plain fquare tiles, clofely fitted 
to each other, on the furface of the 
ground, to preferve the pots from the 
common earth-worm, which, by gaining 
admittance into them, would perforate, and 
alter the confidence of the foil, in fuch a 
manner as to prove very injurious; upon 
this foundation, rows of bricks are to 
be placed in ftraight lines, about two or 
three inches afunder, which will allow 
a free circulation of air under and be¬ 
tween the pots when placed upon them, 
an objefl of great importance, efpecially 
in warm weather, when the air is mod 
' A 
inclined to dagnate, and become impreg¬ 
nated with noxious effluvia. 
The plants, by the above plan, will be 
railed from nine to twelve inches above 
the level of the afiies or platform.
