they may maintain themfelves there for fome time by 
fending forth Roots further and further to a great extent 
all round, to fetch in more remote Provifion ; but at lajl 
all will fail : and they muft either have a freJh fuppfy 
brought to them, or they themfelves be removed and 
tranfplanted to fome Place better furnifhed with Matter 
for their Subjiftence, And accordingly Gardiners obferve 
that Plants that have Jiood a great while in a Place , have 
longer Roots than ufual j part of which they cut off when 
they tranfplant them to a /r/^/Z? 5w7, as now not of any

great many others that might be alledged, point forth a 
Particular terrejirial Matter^ and not Water^ for the 
Subjedl to which Plants owe their increafe. Were it /F^-

tranfplanting them from place to place. The Rain falls 
in all Places alike : in this Field and in that indifferent- 
ly : in one fide of an Orchard or Garden as well as ano- 
ther. Nor could there be any reafon why a Tr^/^S of 
fhould yield Wheat one ll'^r and not the next y
