2. Black Marl. The dark shales that overlie the '"Table 
Ledge " are locally known as the " Black Marl," and the appear- 
ance of these beds well accounts for the name of Black Ven. In 
this cliff the entire division can be studied. The summit of the 
hill is capped by Chert gravel, Upper Greensand, and Gault. 
The base of the Gault is marked by a thin pebbly layer or grit, 
but the formation itself, as remarked by the Rev. W. Downes, is 
pervious to such an extent that springs are thrown out by the 
Lias clay beneath.* It is well moreover to bear in mind that the 
fossils of the Gault and Lower Lias are sometimes commingled 
on the slopes.
