Mr. Hvtton's Notes on the New Red Sandstone, ^c. 65 



Limestone is not seen in the quarry, but it forms the capping of the 

 hill above, and is extensively worked about SOO yards to the east. 



At Brusselton, near the top of the hill, close by the turn of the road, 

 the yellow Sand is visible on the road side. In the great quarry be- 

 neath the tower, there is a very fine display of the Red Sandstone in all 

 its variety of colour and texture, having beds or seams of a hard, light 

 blue, siliceous Shale, running through it in the most irregular manner ; 

 the bed must be here of considerable thickness, as the quarry has been 

 worked at least 50 feet deep. 



In Thickley Quarry, by the side of the Darlington Railway, the same 

 kind of stone is extensively worked, as is found at Park House Quarry 

 and Brusselton. The upper bed is a Slaty Limestone ; a light blueish 

 white Clay occurs here in irregular seams. It was in a quarry a little to 

 the east of this, by the side of the Railway, that the curious deposit of 

 Fossil Fish occurred, which is described by Professor Sedgwick in his 

 Memoir; they were found in a Slaty Limestone bed, very near the 

 Sandstone. 



At Eldon, the Limestone forms the top of the hill, and proceeding 

 northward towards Hotvlish Hall, although the Red Sandstone does not 

 appear at the surface, yet there is sufficient evidence of its existence be- 

 neath, in the deep rich red colour of the soil on the slope of the hills im- 

 mediately under the Limestone. 



At Cowndon, a fault, running nearly north and south, throws down the 

 Limestone, so as to make it abut against the Coal Measures. 



On the slope of the hill rising towards Westerton, near a well, in the 

 middle of a large pasture field, the Red Sandstone comes to the day. 

 At the top of the hill the true relations of the rocks are not easily un- 

 derstood ; the east end of the village is upon Limestone, but there is a 

 Sandstone at the surface in the road about 100 yards to the westward, 

 which is no doubt caused by a fault. This Sandstone may be seen in a 

 small quarry at the west end of the village; but whether it belongs to 

 the Red Sandstone, or to the Coal Measures, is difficult to determine ; it 

 had large coarse grains of Quartz in it, apparently rounded by attrition. 



The Limestone forms the top of the hill above Quarrington, below if
