Notes on the Rocks about Berwick-on-Tweed. By W. 

 GUNN, F.G.S., of H.M. Geological Survey. 



[Read at the Meeting at Berwick, on 13th October 1898.] 



The lowest rocks to be seen in the neighbourhood of 

 Berwick are the Longridge Sandstones, called by the Geo- 

 logical Survey The Fell Sandstones. They underlie the 

 Scremerston Coal Series, and have been a good deal quarried 

 about Tweedmouth and East Ord. They may be observed 

 on the north side of the Tweed, in several places along the 

 new walk between the Old Bridge and the Water Tower, 

 west of the Royal Border Bridge, where they dip at angles 

 from 45 degrees to 60 in a direction nearly east-north-east. 

 South of the river these rocks turn sharply round and dip 

 southward. 



To the east of these, and lying above them, come all the 

 Scremerston Coals and associated rocks up' to the Dun 

 Limestone. The dip of these must resemble that of the 

 Fell Sandstones below, but they are not seen on this side 

 of the river. They crop out under that part of the town 

 nearest to the river. 



The lower part of Tate's Calcareous Division, embracing 

 the Dun and Wood End Limestones, are also hidden here. 

 They must strike northwards, standing nearly on end, 

 through the higher part of the town, and southward to the 

 foreshore south of Spital, where they may be seen at low 

 water dipping east-north-east at 30 to 35 degrees. 



If we pass, at Berwick, through the Ness Gate, and 

 examine at low water the foreshore between it and the pier, 

 we shall come first on sandstones and shales with an easterly
