The actual amount of underlay seen here bringing the vertical 

 sandstones, &c, beneath the vertical limestone is very small, yet probably 

 extends to the whole thickness of the limestone, 80 or 90 feet, as this is 

 completely cut out, unless, indeed, there be another shift of the beds on 

 the southern side of the limestone also where the red clays are not seen.
