THE other kind is a grey, and fomctirnes a 

 dark grey lime-ftone, confifting of a compact 

 calcareous-ftone, mixed with grains of fpar, 

 of the facne colour. When broken, it has 

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

 petrified ftriated (hells or pe&inites. The 

 greateft part of thefe petrefadtions are^ 

 however, only impreffions of the hollow 

 fide of the (hells. Now and then I found 

 like wife petrefied pieces of the fhell itfeif* 

 though I could never find the fame ihells in 

 their natural ftate on the (hores 5 aod it fe.ems 

 inconceivable how fuch a quantity of im- 

 preffions could come together, as I fhall 

 prefently mention. 



I HAVE had great pieces of this lime-ftone, 

 confifting of little elfe than pedtinites, lying 

 clofe to one another. This lime-ftone is 

 found on Several parts of the ifle, where it 

 lies in horizontal ftrata of the thicknefs of 

 five or ten inches. This ftone yields a great 

 quantity of white lime, but it is not fo good 

 as the former, becaufe it grows damp in wet 

 weather. 



FIR-WOOD is reckoned the beft for the 

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

 The wood of the fugar-maple, ag<l other 

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

 becaufe they leave a great quantity of 

 coals.
