C 36 3 



rc well known to every practical hufbartdfnanj 

 " for there is no land, though it may be ever fo 

 " fertile, but by conftant cropping may be ex- 

 fC haufted, and reduced to a ftate of barrennefs* 

 " But it does not follow, that fallowing is abfo- 

 u lately nccefTary to reftore its fertility, becaufe 

 •' where a fufficient quantity of manure can be 

 •J obtained, its fertility may be reftored without 

 <c fallowing. And on this fcale of management, 

 " the longer land may be under cultivation, it 

 w would be fo far from being impoverifhed by it, 

 cc that it would be in a conftant ftate of progreflive 

 u improvement." 



To this it was objected, by a very refpectable 

 and ingenious member prefent, (the Rev. Mr. 

 Hall) that the opinion was not well founded, for 

 he had known inftances wherein fertility could 

 not be reftored by manure, and mentioned fome 

 garden or gardens within his own knowledge. 

 To this the' writer replies, the objection fuppofes 

 what the pofition does not afTert or maintain* 

 Had it been afferted, that the fertility of land in- 

 creafeth in proportion to the quantity of manure 

 laid upon it, the objection might have been good; 

 but he knows little of vegetation, or of the im- 

 provement of land, who knows not that it may be 

 rendered unfertile, at leaft for a time, by laying 



too
