I. The grand foflil manure of Norfolk is 

 MARL; through whofc fertilizing quality^ 

 judicioiifly applied, lands, which feem by 

 nature to have been intended as a fcanty 

 maintenance for fheep and rabbits, are ren- 

 dered capable of fattening bullocks of the 

 largeft fize, and of finifl|ing them in the 

 high eft rnanncr. 



There are, in this Diftrift, two fpecies pf 

 marl, very difcind: in their general appearances j 

 though their quality of fertilising be fimilar. 



The central and northern parts of the 

 Diftrid: abound, upiverfally, with a wjliitiih- 

 coloured chalk-marl ; while the Fleg Hun- 

 dreds, and the eaftern coafl, are equally fortu- 

 nate in a ffrev-coloured clay-marl. 



The firfl has, in all probability, been ip 

 vfc as a manure many pentpries ; there are 

 oaks of confiderable fize now going to decay 

 in pits which have obvioufly been heretofore 

 in ufe, and vyhich.a perhaps, flill remain in 

 uie, as marl-pits. 



The ufe of clay-marl, as a mianure, feems 

 to be a much later difcovery ; even yet, there 

 are farmers who are blind to its good effed: ; 

 becaufe it is not 77jari, but ^' clav;" by which 

 name it is univerfaliy known.
