Mr. Hutton's Notes on the New Red Sandstone, ^c. 67 



thickness, as the Red Sandstone was immediately come upon, and was 

 sunk into to the depth of 29 feet ; the upper part was micaceous, split- 

 ting into thin layers, but the stone became more compact as the opera- 

 tions were carried deeper. 



- In a little dell near Westoe, called the Deans, behind a house called 

 Brinkburn House, the Red Sandstone occurs, and I am informed by a 

 gentleman well acquainted with the neighbourhood, that some years ago 

 the yellow Sand was worked in a pit near to Harton Toll Bar, on the 

 turnpike road from South Shields to Sunderland. At the mouth of the 

 above-mentioned dean, near a brewery, a Sandstone of the Coal Mea- 

 sures is visible, on the western side of the burn ; rising to the top of the 

 hill, on the opposite side, we find the New Red Sandstone, in Mr. Fox's 

 quarry, which has been extensively worked for a building stone ; it may 

 be again seen in the Colliery Quarry, on the road side leading to Westoe. 

 The Magnesian Limestone, which forms the capping of the hill, being 

 also worked in an adjoining field. 



In a quarry at Lay Gate, near South Shields, the Red Sandstone forms 

 the upper bed, and rests upon a white Sandstone, which is evidently, 

 from its general characters, a Coal Grit, having abundance of vegetable 

 remains in it. This quarry was the last point at which the red rock 

 was observed South of the Tyne ; but on the north side it occurs again, 

 forming the cliffs below the Spanish Battery. Here neither the Lime- 

 stone nor the yellow Sand appear, but on the otiier side of Tynemouth 

 Haven the Limestone forms the uppermost bed in the Castle Cliff, and 

 at its lower part alternates with the yeUow Sand ; the latter is upwards of 

 20 feet thick, and is seen resting upon the Red Sandstone, which forms 

 the whole of the lower part of the cliff on its south and eastern faces. 



A well-known Basaltic Dyke here cuts through the red Sandstone, 

 and the yellow Sand, but is not seen in contact with the Limestone. In 

 the eastern face of the Cliff, several faults appear traversing and affect- 

 ing alike the whole formation. 



At the base of the cliff, on the northern side, in Bercy Haven, a Coal 

 Sandstone makes its appearance, rising rapidly towards the north-west, 

 being surmounted by the superior formation ; both members of which
