64 Mr. Hutton's Notes on the New Red Sandstone, 8^c. 



is the yellow Sand, and beneath this the Red Sandstone, which is here 

 thin, and of the very micaceous variety. The upper part of the yellow 

 Sand is hard, apparently from the infiltration of calcareous matter from 

 the Limestone, 



Heugh Hall Hill is principally of Limestone, but near the bottom of 

 its northern slope, the Sand makes its appearance having bands of a red 

 colour in it, marking the planes of stratification ; in a field at the foot of 

 the hill called " Red Brae Bank," the Red Sandstone has been lately 

 bored through in search of Coal. 



On the slope of the hill above Pittington, both members of this for- 

 mation may be seen cropping out beneath the Limestone, but of incon- 

 siderable thickness ; the Sandstone is of the micaceous variety, splitting 

 into thin leaves. 



Near a Limestone quarry on the hill between Pittington and Moorsley, 

 a thin bed of the same red micaceous shaly Sandstone appears, having 

 above, or in it, a seam of blueish-white unctuous Clay. The quarry here 

 is extensively worked in the slaty Limestone ; a kiln is built upon the 

 yellow Sand, which, at its upper part, has hard beds of a calcareous na- 

 ture alternating with it. 



The same light-coloured Clay is visible on the side of the footpath 

 leading towards Moorsley, and still further on, about half a mile short of 

 that place, the yellow Sand again appears beneath the Limestone. 



At Moorsley, a new pit has been sunk by Mr, Russell, which was be- 

 gun upon the yellow Sand, and immediately below the Limestone. The 

 Sand is here about 16 feet thick, and the red Sandstone 3 fathoms, having 

 a Shale bed beneath it. 



In sinking the old pit, at Hetton, below the yellow Sand, the red 

 Sandstone was found, between three and four fathoms thick, this bed is 

 here well known and calculated upon by the sinkers, as unconformable 

 to the Coal Measures, it having been proved by borings in search of 

 Coal, in many places in the neighbourhood. 



In the Downs Pit, at Eppleton, the sinking was through a dry yellow 

 Sand, about six fathoms, and the Red Sandstone three fathoms. 



The quarry, in Bough Dean, near Houghton-le-Spring, displays the
