WEEDS. 1^8 



But is signifies little for one farmer to destroy the thistles in 

 his ground so long as they are suffered to flourish in contigu- 

 ous fields ; because the seeds are wafted in the air from field to 

 field, to a considerable distance. For this reason it is, that ia 

 France, a man may sue his neighbor for neglecting to thistle 

 his ground in the proper season ; or may employ people to do it 

 €it his expence. 



The great importance of keeping tillage lands clear of weeds' 

 was probably one great reason which led to the introduction of 

 the drill husbandry among the European farmers ; asby leaving 

 the grain very thin between the drill rows of culmiferous crops, 

 as wheat, rye, barley, &c. a passage between the drill beds is 

 tnereby provided, by which more convenient access is had to 

 the grain for the purposes of clearing the weeds from thera. 



The weeding of culmiferous crops, when sown in the broad 

 -cast way, is much practiced in Europe, and great additions 

 are believed to be thereby gained to the crop.
