GEOLOGY OF THE EAST CLIFF. 139 



characterised by a curious bubble-like surface; 

 in this bed the hemispherical forms turn 

 downwards, whereas in the bluestone bed in 

 the Ashdowns, the same curious formation is 

 noticeable, but the " bubbles " turn upwards. 

 Infiltration appears to be the cause. 



Between the base of the clays and the 

 main "blue-stone" bed, there are two or three 

 bands of iron sandstone, and clay ironstone. 

 Ironclay nodules also occur both below and 

 above the main " bluestone " bed. 



At " Foulness," (or " Fowlness "), the slip 

 under the flag-staff on the East Cliff, a "fault" 

 or fracture has brought down the beds on the 

 north east side from 30 feet to 40 feet, showing 

 some thickness of blue clays and shales over- 

 lying the main " bluestone " bed, and super- 

 imposed, in their turn, by 10 feet of buff 

 sandrock, with sandy clays above. These 

 beds on the south-west side have been levelled 

 by denudation. The sandrock bed may be 

 seen also at the " Gringer,"* a small gap 

 between Ecclesbourne and Fairlight.

* Gringer, derivative (?) Gringotter, Fr., to warble, in allusion 

 to the sound of trickling water (?).
