the worthlefihefs of the dung of horfes at 

 grafs. 



This, when the fuperior value of their 

 dung in the ftable is confidered, appears 

 fomewhat paradoxical. The idea, however, 

 is not confined to this Diftrid:, nor to this 

 Ifland ; it prevails, I am well informed, in 

 America, and perhaps more or lefs in every 

 place where hufbandmen obfervc fuperfi- 

 cially. 



The idea has, no doubt, fome foundation. 

 The dung of horfes dropped on grafs in fum- 

 mer loon undergoes a change. Its fubftance 

 is prefently fcooped out by infeds; nothing 

 but a porous bundle of undigefted vege- 

 table matter being left. If infedts not only, 

 eat horle-dung, but fly away with it out of 

 the field, it is in reality loft to that parti- 

 cular field -, but if, what is moft likely, they 

 drop it again near the place where it was 

 taken up, and at length find a grave for their 

 own bodies among the grafs, the occupier of 

 the land fuftains no lofs,. 



SHEEP, I believe, are feldom mixed either 

 with cows or fatting-cattle. They eat lefs 

 fair than horfes, which ftick to particular 



. patches ;
