Basin of the Eden and north-western coasts of Cumberland, &c. 407 



Codlin Rock, two reefs to the south of Ravenglass, only seen at low water ; on the Cross House 

 estate, half a mile north of Bootle ; and, lastly, in wells and other excavations at Mopus, Hise 

 Moor, Well Bank, and Old Highton, all in the same neighbourhood, and on the north side of the 

 Bootle rivulet. 



Crossing the estuary of the Duddon to the limestone of Roan Head, we find the superior rocks 

 concealed under blown sand ; but the new red sandstone breaks out south of Wet Flats, and may be 

 traced by Little Mill, Billing Coat, and Newton ; and thence by Bousfield, Stank, and Hole Beck. 

 Beyond the last-mentioned place everything is buried under alluvial accumulations to the sea-side ; 

 but at low water the red sandstone is seen just to the north of Rampside. It appears also at the 

 north point of Old Barrow Island. 



In the Cartmel promontory the new red conglomerates appear at Rougham Point, west of 

 Humphrey Head; and the red sandstone is said to have been reached by boring between Cannon 

 Winder and Ravend's Winder, and close to Lower Hosker. 



By help of the preceding notice, the demarcation of the new red sandstone may be laid down on 

 the large county maps with a near approach to accuracy. Had the Ordnance maps of the northern 

 counties been published, such details would have been perfectly useless, as the information would 

 have been more correctly conveyed by a superficial colour, than by any verbal description.
