FOR fince that the Head of this Tree in its natural Growth, when 
its Roots were all perfect and fixd in the Earth, did then make fuch a

IN this very Point of Planting-many People ‘are’ much out, becaute 
that reducing the Heads of Trees at firft Planting, caufes them to have 
a lefler Appearance than they defire, and therefore will not fuffer them 
to be reduced proportionable to their Roots ; fo that they “eithér ‘remain 
in a decaying languifhing State, ot inftantly dic; for their Roots being 
much reduced by removing, they cannot imbibe Moifture fufficient for the 
Support of their. Heads, which are then in too great a Quantity. Therefore 
“tis always to be remembred, at the Time of Pruning and Planting, 
that the greater Proportion the Area of the Roots bears to that of their 
Leaves, fo much the more they will be enabled to imbibe: Nourifhment 
for the Support of the Plant, which confequently will thereby be rhioire 
vigorous in its Growth, and better able to endure dry Seafons, Cc, 
NOW, in Confideration that this Experiment has proved, that the 
Sap, which is the Life of Vegetables, (as Blood is of Animals) mutt 
pals much fwifter thro’ the Surface of thé Roots than Leaves, it therefore 
‘Olows, ‘that ‘tis very reafonable, when Treés of any Kind: are’ taken 
out of Nurferies, ec. for tranfplanting, their Roots fhould be preferv'd 
at as great a Quantity as is poffiblé, that Nature may have the greateft
