will tliffufe themfelves to an unlimited dif- 

 tance. Every joint of the root is in ciTecl a 

 feed^ which only requires air and openncls of 

 foil to fit it for vegetation, and enable it to 

 fend forth frefli roots ; and confequently to 

 furnifli the foil with a frelh fupply of feeds. 



The nature of couch-grafs, and its method 

 of propagation, being duly confidered, the 

 method of deflroying it evidently appears. 



To free the foil from the feeds of weeds 

 which are lodged in it, we endeavour to place 

 them in a fituation favourable to vegetation; 

 and, as foon as they have vegetated, to dellroy 

 the feedling plants while yetinatcnderflatej 

 thus converting the feeds into a melioration 

 of the foil. 



The fame principles of managenient are 

 applicable to the roots of couch-grafs. Break 

 up the foil in fuch a manner as to give it the 

 greateft furface, in order to encourage in the 

 ampleft manner poiTible the vegetation of the 

 roots. As foon as this isefrciftcd, endeavour 

 to dellroy the young fuckers while they are 

 yet in a delicate tender (late, before they have 

 had time to eftablifh themfelves, or to fend 

 ouK frefh roots for the purpofj of propagation.
