Tis therefore probable, that the roots of 
trees and plants are thus, by means of the 
Sun's- warmth, conftantly irrigated with 
frefli fupplies of moifture 5 which, by the 
fame means, infinuates it felf with fome 
vigour into the roots. For if the moifture 
of the earth were not thus actuated, the roots 
muft then receive all their nourifhment 
mcerly by imbibing the next adjoining 
moifture from the earth ; and confequcnt- 
ly the fhell of earth, next the furface of the 
roots , would always be confiderably drier 
the nearer it is to the root 5 which I have not 
obferved to be fo. And by Exper, 1 8 and 
19, the roots would be very hard put to it^ 
to imbibe fuffident moifture in dry fum- 
nicr weather, if it were not thus conveyed 
to them, by the penetrating warmth of the 
Sun ; Whence by the fame genial heat, in 
conjundion with the attradionof the capil- 
lary fap vcflels , it is carried up thro’ the 
bodies and branches of vegetables, and 
thence palTing into the leaves, it is there 
moft vigoroufly aded upon, in thofe thin
