Etherley, showing the position 

 and thickness of the various 

 coals. 



The Measures above the 

 Brockwell are exposed in vari- 

 ous quarries, railway cuttings, 

 and natural sections. They 

 may be seen in quarries at 

 Shildon, Brussleton, Etherley, 

 Evenwood, and other places ; 

 in cuttings on the railway 

 crossing Cockfield Fell, and 

 more especially in sections ex- 

 posed in the Gaunless Valley, 

 where both the Five Quarter 

 and Brockwell coals outcrop. 

 But in this district, as in all 

 other parts of the coal-field, it 

 is from the many pit sinkings, 

 borings, and other works in 

 connection with coal mining, 

 that a knowledge of the Mea- 

 sures is best obtained. It is 

 therefore with pleasure that 

 we are able to give, through 

 the courtesy of W. C. Stobart, 

 Esq., three of the following 

 borings and pit sections that 

 have been put through the 

 Measures on the Etherley and 

 Newton Cap royalties ; as well 

 as a boring put down on Cock- 

 field Fell by the owners of the 

 New Copley Colliery. The 

 first given (No. 1) is the most 

 south-westerly, being situate
