Heap of Sand as before; bur if ‘tis moiften'd in the fame Manner 
with Oil, and laid in the Sun to dry, it will incorporate, and 
become a very hard Subftance. So, from hence ‘tis very probable, 
that different Natures, Colours, and Textures of Earths, are alterd, ac- 
cording to the feveral Natures of the various Juices with which they 
are mixd., | ‘ 
NOW feeing that Oily Juices will incorporate with Sand, and become 
a hard rough Subftance, and that more or lefs in Proportion to the 
Quantity of the Oily Particles contained therein ; ’tis very probable that 
from thence it is, that the feveral Sorts of oe are generated. 
THE fevers Colours of both Sand and Clay, may very probably 
proceed from the different Colours of their Juices ; for Sand moiften’d 
with Water has a different Colour from that mix’d ah Milk, Oil, Ce. 
Experience demonftrates, that Sand mix’d with Clay, makes a coiieaiaad 
Earth called Loam ; 3 which-differs in its Nature, weaning to the Pro- 
portion contain’d inna each other. 
EQUAL Sk of Sand and Clay, perfectly mix’d together, | 
~~ makes the beft (and is called a Middling) Loam. 
yA WO Thirds Clay, § and one Third Sand, makes a very ftrong Loam, 
Be: led rick -Farth.. -Thefe two Kinds of Loams are the very 
‘be S Soils for Apples, Pears, Plumbs, Apricots, and Quinces: The firft 
for. the Surface, or firft Strata ; and the laft for the Bottom, or <— 
Strata. 
\ Two Thirds Sand, and one Third Clay, makes a light Loam, 
~ ufaally called Light-Land. Thefe two laft are the beft Soils for Cherries, 
~ Peaches, Figs, Vines, doc. this laft Compofition being the fir Strata, 
or Surface, and the preceding the Bottom or next lower Strata.
