-may probably hurry the terreftrial Matter thorow their 
, VeJfeU top faft for thein to ar r ejt Qini lay hold of it. Be 
that as it will, 'tis moft certain there are peculiar Soils 
that fait particular Plants. In England^ Cherries are ob- 
"^*\y ^ ferved to facceed heft in Kent : Apples in Herefordfiire : 
V""' Saffron in Cambridgejljire : Woad in two or three of our 
Midland Counties : and teazles in Somerfetjhire. This is 
an Objervation that haih held in all Parts, and indeed in 
Ages o{ ' World, The nioft ancient Writers of 
"* Vid. Varro- Hujbandry took Notice of it ; and are not wanting 
J2''^^^tr/f ^^1^ making choice of fuiced to the

But, which is a further Proof of what I am here en- 
deavouring to advance, that Soil that is once proper and 
fit for the Production of fome one fort of Vegetable does 
not ever continue to be fo. No, in Tra5t oj time it 
lofes that Property: but fooner in fome Lands ^ SiUd la- 
ter m others. This is what all who are converfant in 
thefe things know very well. If Wheats for Example, 
be fown- upon a Trad of Land that is proper for that 
Grain, iht fir fl Crop will fucceed.very well: and per- 
haps the fecond^ and the thirds as long as the Ground is 
in Hearty as the Farmers fpeak. But in a few Tears 
^twill produce no more^ if fowed with that Corn, Some 
other Grain indeed it may, as Barley. And after this has 
been {own fo often that the Land can bring forth no more 
of the fame 5 it may afterwards yield gooi Oats : and 
perhaps Peafe^fitx them. At length 'twill become Bar- 
;ren \ the 'Vegetative Matter ^ .that at iirft it abounded 
withal, being educed forth of it by thofe fuccejjive Crops^ 
and moft of it born off. Each fort of Grain takes forth 
that peculiar Matter that is proper for its own Nourijh-- 
ment, Firft thQ Wheat draws off Particles that
