Many of thefe waftes are on limeftone; 

 but it is obfervable, that experience gives 

 us no very great encouragement to ufe 

 lime on all limeflone lands : upon moors, 

 which abound with ling and black earth, 

 it is not only expedient, but abfolutely 

 neceflary j but the foil is utterly different, 

 from the light, thin, limeftone loam, or 

 loofe hazel mould, that is generally found 

 in the countries in quefcion : no conclufion 

 of this fort is to be taken as univerfal ; 

 there certainly are trails where lime is ad- 

 vifeable, but particular exceptions would 

 lead me into too minute a difcufllon. I 

 fliall not therefore notice any improvement 

 by lime. 



If from experience we recur to reafon, I 

 think the obfervation will fland good; 

 lime fhould never be applied to poor foils, 

 without their being otherwife well manur- 

 ed ; for as it acls as a ftimulus to force the 

 foil to yield its nourifliment, it will reduce 

 poor land to a caput mortuum : now the 

 wolds and downs I fpeak of, are poor, and 

 many of them thin ; lime, therefore, cer- 

 tainly muft be improper ; but in the moors, 

 of which I before treated, the cafe is to- 

 tally different : the foil in reality is a deep 

 2 dunghill.
