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; which, by the 
fame means, infinuates it felf with feme 
vigour into the roots. For if the moifture 
of the earth were not thus actuated, the roots 
muft then receive all their nouriftiment 
meerly by imbibing the next adjoining 
moifture from the earth ; and confequent- 
ly the (hell of earth, next the furface of the 
roots, would always be conftderably drier
