These gritty bands come to the coast at Man Sands and Scabba- 

 combe Bay. If we follow the arenaceous rocks on the north of the 

 "Floating Bridge" to the westward we find them to range by Little 

 Combe, and by Tidaford and Woolcombe to Collaton, Morleigh 

 Down, Black Down, and Lee Moor, and then to curve south-west 

 by Stubston, Sherlangston and Torr, to near the mouth of the Erme.
