Wherethefe prunings had been try<jd upon Trees 20 
Foot high ; the difference of their Increafe, was fenfible 
the following Summer, but in 7 or 8 Years time, thediffe. 
rence is prodigious ; the ua-pruned Trees growing feveral 
times bigger than the pruned, both in Body and Branches, 
even to Admiration. 
He hath often obferved/alfo that when the top Branches 
would fhoot out and grow 2 Foot, or more, in length ; 
the lower Branches would not fhoot above 4 Inches. And 
further, that in the Branches of the Fir, thi Joynts 
above the Rings barked round, would increafe and grow 
much bigger in 3 Years, than they would in 5 Years, if 
the faid Rings were not cut off. 
The fame Ferfon upon Dilcourfing fome, other parti- 
cular Inquu'ies about the Spreading and Increafe of the 
Roots, affured me, that he had obfSrved a very large P/- 
about two Foot and an half in Diameter, and of a 
heighth propoi tionablefi;/;^: of about 20 Yards ; the loweft 
Boughs of which, were about 30 Foot above the Grou nd) 
did ipread and flourifh on every fide a like, though it had 
no Root at all towards three quarters of its Situation, but 
only toward one quarter, into which it fpread its Roots 
very farr and large,divers of them reaching about 70 or 8 o 
Foot from the Body of the Tree ; The Reafbn of which 
fpreading was occafioned by its being planted juft within 
the iquare Angle of the Corner of a deep thick and ftrong 
Stone Wall, which 'was a kind of Banking or Wharfing a- 
againft a River that ran by it; This. Tree l fay, tho' it 
had nourifhment only from one quarter of four to its 
Roots, yet did the fame flourifh and fpread equally on e* 
.very fide., - 
Uaoja ConiJ^ratioi of thefe and divers other Ob- 
fervations, and Experiments Mr. Brotherton is of Opinion. 
I That the Sap (moft of it if not all) afcends in the VefTels 
of the lignous part of the Tree, and not in the Cortical 
Fj^rt, nor between the Cortical and Lignous parts.
