316 ROOKS ABOUT BERWICK-ON-TWEED 



A level was formerly driven in this lower coal that crops 



out near the beach, and a shaft sunk 20 fathoms to a still 

 lower coal, the section of which was : — 



Rough Coal . . . . . . 1 ft. 8 in. 



Fire Clay, very fine in quality . . 2 ft. in. 



Hard Coal . . . . . . 1 ft. 4 in. 



5 ft. in. 



This may have been the Fawcett Seam. It does not 

 seem far enough from the Dun Limestone to be the Screm- 

 erston Main Coal. The coal was poor, and the working 

 unprofitable. Except as given above, the Scremerston Coal 

 Series is not exposed on this coast, but the whole series 

 must be below at these Lamberton Pits. As they do not 

 crop out farther to the north, it would seem they must be 

 entirely faulted out in the series of disturbance that come in 

 about Hilton Bay and near the Lamberton Fishery Station. 

 A large part of the Fell Sandstones seems also missing 

 along this coast, and there appears to me to be wanting 

 at least 1000 feet of strata. 



There is, however, a very fine section of a great part of 

 Tate's Tuedian Series, with its characteristic cement stones 

 or thin impure limestones, exposed between Ross Point and 

 the fault at Burnmouth, which throws them down against 

 Silurian Rocks. The beds are everywhere dipping steeply, 

 or are vertical. Sometimes the dip is a normal one to the 

 east; but in many places the beds have been inverted, and 

 the rocks now dip to the west. It must be remembered, 

 however, that the lowest beds of the series are next the 

 fault at Burnmouth, and that whatever way they are 

 dipping, there is a regular descending series of beds from 

 Ross Point to Burnmouth, probably exceeding 2000 feet 

 in thickness.
