It will not then be difficult to underlland that the 

 eleftrical matter, conveyed in the water, inflead of 

 penetrating deep into the ground, is obftrufted by the 

 flints,* and collefted about the roots of the gralTes, 

 where it enters, and becomes a mod active and pow- 

 erful agent in vegetation. 



This opinion is however advanced with diffidence. 

 The fa6ls which gave rife to it are flriking, and the 

 difcovery may be ufeful; it may affifl the philofo- 

 pher, in explaining or accounting for fome of the 

 principles of vegetation^ and may encourage the 

 hufbandman to form water-meadows on fimilar prin- 

 ciples, wherever circumflances will admit of it.

• The learned and celebrated Dr. Ingenhouz, of Vienna, has in- 

 formed the writer that he has made experiments on flints, which prove 

 them to be non-condudlors, or bodies which flop the progrefs of elec- 

 trical matter. He thinks that the intelligence conveyed in this paper 

 is very important ; and concurs with the writer in accounting for the 

 fertility of the meadow.
