No proper thickness is given of the

From the surface to Bilstone mine 

 is estimated at 26^ fathoms.

Horth Coal, 



Beneath the north coal I believe 

 that there is bituminous shale 

 with ironstone bands, and free- 

 stone. 



And below these strata is, 



Limestone, contain- 

 ing- marine remains, 



Consisting of limestone blaes, or an 

 impure limestone, in which occur 

 three seams of pure limestone. 



The interval between the North 

 coal and North-Green seam is 

 estimated at 



llTorth-Green Seam of 

 Coal (at present wrought out), 

 lying beneath the limestone,
