PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Mar. 19, 



stone is seen at the bridge over the Eden, on the highway from 

 Appleby to Penrith, to a slight extent. Near this is Crowdundle 

 Beck, separating Cumberland from Westmoreland, in which we have 

 a fine section of the argillaceous series. This extends from Acorn 

 Bank to beyond Newbiggin, and is devoid of gypsum. It exhibits 

 the same direction and angle of dip as at Hilton Beck, and is also 

 succeeded by the upper sandstones, which are extensively worked at 

 Crowdundle quarry. The same sandstone is also seen at Culgaith, 

 and forms the escarpment known as Culgaith Peel ; and immediately 

 below it, on the opposite side of the Eden, the argillaceous series are 

 well exhibited, forming Haa Plaister Scar, on the property of Winder- 

 waith. 



The section at Winderwaith is as follows : — The upper portion red 

 clays, 12 feet thick, beneath which are greenish-grey clays with thin 

 gypseous bands, 9 feet; red and grey clays and thin gypsum, 4 feet; 

 a bed of fibrous gypsum, 2 inches, — the thickest seen, resting upon 

 6 inches of clay, passing downwards into an argillaceous sandstone. 



Down the Eden on the east side, the argillaceous series forms a 

 well-marked escarpment; and on the west side of the river the 

 inferior sandstone is occasionally seen. The latter is, however, 

 very well exhibited in the Eamont, a short distance above its junc- 

 tion with the Eden, for about a mile and a half. In this section 

 the false bedding is so abundant that on account of it no idea could be 

 arrived at concerning the arrangement of the inferior sandstones. 



§ 5. Section from the West of Penrith to Hartside. (Eig. 3.) 



West of Penrith, the junction between the Carboniferous rocks on 

 the W. and the sandstone deposits on the E. is not apparent.

At N'ewton Eaigny and Catterlen, a purple grit of the Carboniferous 

 series has been noticed by Prof. Sedgwick*. This grit is seen in the
