These coal-pits are not sunk through the lias, which is found on the hills, but 

 through the red marl in the valleys. There is but little red marl on the sur- 

 face in the parish of Stanton-Drew, where you arrive almost immediately at 

 the coal measures. At Sutton and Faringdon, the red marl varies in thick- 

 ness from 4 or 5, to 12 or 14 fathoms.
