The other kind is a gre^/, and fometimes a 

 dark grey lime-ftone, coniifling of a compacfl 

 calcareous-done, mixed with grains of fpar, 

 of the fame colour. When broken, it has 

 a ftrong fmell of flink-ftone. It is full of 

 petrified flriated (h&\h or ped:inites. The 

 greateft part of thefe petrefa(5i:ions are^ 

 however, only impreilions of the hollow 

 fide of the fliells. Now and- then I found 

 likewife petrefied pieces of the fliell itfelf, 

 though I could never find the fame fiiells in 

 their natural ftate on the {liores 3 and it feems 

 inconceivable how fuch a quantity of im- 

 preffions could come together, as I fhall 

 prefently mention. 



I HAVE hadgreat piecesof this lime-done^ 

 confifting of little elfe than peclinites, lying 

 clofe to one another. This lime-flone is 

 found on feveral parts of the ifle, where it 

 lies in horizontal flrata of the thicknefs of 

 five or ten inches. This flone yields a great 

 quantity of white lime, but it is not fo good 

 as the former, becaufeit grows damp in wet 

 weather. 



Fir- WOOD is reckoned the befl for the! 

 lime-kilns, and the thuya wood next to it. 

 The v/ood of the fugar-maple, and other 

 trees of a fimilar nature, are not fit for it, 

 becaufe they leave a great quantity of 

 coals.
