THEN the Nourifhment truly natural to the Oak, is of each an 
+ equal Quantity: But when thefe Principles are unequally mixt, be it more or - 
def, in any other Soil, and the Oak is tranfplanted therein, the Growth 
will be retarded proportionably; becaufe the unequal Mixture of the 
feveral Principles are difproportionable to thofe of which the Oak is com- 
poled. 
HENCE it is that Alders, Willows, Poplars, ¢c. which have 
great Quantities of Water in them, cannot thrive in hot and dry Lands. 
And contrarily, the Oak, Beech, Cherry, Peach, °c. cannot thrive in 
very wet Lands, where the Quantity of Water is in too great a Quanti- 
ty for their Support, which rather difunites their Principles, than fapports 
them. Therefore to be certain of adapting every Plant to its proper 
~ Soil, we muft firft examine the exa& Quantities of each Principle that’s 
contain d in every Plant we would propagate, as alfo in the Soils we in- 
"tend to cultivate, And then, if we plant our feveral Soils with fuch Ve- 
getables whofe Principles are found to be equal, or nearly equal to thofe 
of the Soils, we may affure our felves of Succefs, and work with Cer- 
tainty ; whereas what has been hitherto well done by every one in Plant- 
ing and Gardening, has been by mere Chance only. 
Reach of ordinary Ca Dal ities, ‘and require abundance of Accuracy, Judg- 
- ment, and Time, which ‘may hinder many from making Refearches 
therein; but were fuch a Work judicioufly compleated, ‘twould render the 
Practice of Gardening certain and fucce(sful, 
‘TIS truc, that thele Inquiries into Vegetable Nature are beyond the

ET is with no fmall Concern, that the great Hurry of Bufinefs, and 
Want of Time, have prevented the compleating of thefe fo-much wanted 
Experiments, which I fhould gladly have obliged the World with, at this 
Inftant, fince they are the very Bafis and Life of Planting and Gardening. 
But if Life permits, I fhall very fpeedily accomplifh them ; which with 
7 © grearelt Accuracy and Juftnefs will be communicated, that every 
Lover-of Planting and Gardening, may have a true Underftanding of their 
~ feveral different Natures and Qualities, and thereby be always certain of 
their defired Succefs, |
