The Frurt-Garpvewn [Iluftrated. 
THE Depth of thefe two Stratas taken together, needs never be 
more than two Feet, (véz.) The firft Strata, or Surface, 16 Inches, and 
the Bottom, or next loweft Strata, 8 Inches : For whatever Nourifh- 
ment is imbibed by Trees below this Depth, is crude and undigelted 
for want of Heat; therefore whenever Fruit Trees are fuffer'd to 
{trike their Tap-Roots fo very deep, they immediately become luxurious, 
and their Fruits infipid, ta the over and above Crudity of the Sap im 
bibed from below. 
IT has been the Pragtice of many eminent Gardeners, to make their 
Borders for Fruit Trees full three Feet deep ; and Mr. Wife and Mr. 
London, nay, and even Mr. Carpenter alfo, recommends the making of 
Earth full three Feet deep, in their French Tranflation of the Retired 
Gardener, without confidering the spies Degrees” of Heat in the 
Earth, from 1 to 36 Inches deep. 
THE Reverend and Learned Mr. Hales, in his Vegetable Staticks, 
p- 64. has proved, That at two Feet Depth, ‘tis 27 Degrees colder than 
on the Surface, and confequently the deeper we go afterwards, the more 
colder.and crude is the Nourifhment. 
IF we are fo happy as to have the Liberty of making our own 
Choice of a Soil for our Plantation, I advife that it be Land which 
has not been difturbed by either Spade or Plough within-the Space 
of 50 or 60 Years, and continually fed with Cattle: That it be a 
kind, moderate, fandy Loam, of two Spits in Depth, its Bottom ‘incli- 
nable to a Brick-Earth, with a moderate Reclination towards the South, 
or South declining Eaft about 20 Degrees; and the Springs about ten, 
twelve, yc. Feet below the Surface. 
TO make Choice of Soils, by their Smells, Taftes, coc. as Mr. Wife 
agrees to, in his Treatife aforefaid, is very difficult ; for notwith- 
ftanding that their Steams, or Taftes; may be difagreeable to our Pa- 
lates, yet “tis very probable that they may be agreeable to Plants, when 
Nature has prepared them fit for their Nourifhment. Befides, ’tis not 
_ in our Powers to determine the Nature of Soils by Smell or Tafte ; be- 
caufe that all Soils contain a great Variety of Juices ; fome neceffary for 
the 
?
