 vigour into the roots. For if the moifture 

 of the earth were not thus actuated, the roots 

 muft then receive all their nourifliment 

 meerly by imbibing the next adjoining 

 moifture from the earth ; and confequent- 

 ly the fhell of earth, next the furfaee of the 

 roots , would always be confiderably drier 

 the nearer it is to the root ; which I have not 

 obferved to be fo. And by Exper. 18 and
