yb Mr. Ltvinojhii's Expenraents on Luceriir 



There are two confiderations which render weeds here iel'j 

 troublefome than in Britain ; the [sverity of our zvinter, and 

 the Jicat of our jiimmer. Many, from the firfl of thefe caufes, 

 are annual here, which are perennial there, by being able to 

 live thro' their mild winter. The ilightefl fallowing in the heat 

 of fummer, kills mod weeds here, while in England their moid 

 climate enables the greatefl part of them, like Anteus, to bid 

 defiance to wounds and bruifes, if they are permitted but 

 to touch their parent earth. We may add to this that the 

 indigenous weeds of this country are few, becaufe the children 

 of the foreft, as well of vegetable as of animal tribes, fly the 

 haunts of men ; the only troublefome weeds we have are 

 convidls, that have been tranfported from our mother-country 

 — They muft therefore, neceflTarily, be much fewer than thofe 

 that remain behind, not only becaufe the habits of many of 

 them are too delicate to afTimilate themfelves to our unpolifhed 

 climate, but becaufe their number, in both countries, muff 

 be proportioned to the time from which they began to be 

 cultivated, and to the extent of their commerce — for ivceds 

 and vices are the children of cultivation and commerce. Nor 

 will they ever be eradicated in an improved country till fome 

 agricultural millenium fliall advance cultivation to the higheft 

 pofTible point of perfetSlion : All thefe confiderations form 

 decided arguments in favor of the cultivation of lucerne (whofe 

 greatell enemy is faid to be weeds) in this country, rather than
