RIVER WEAR SUB-DIVISION EAST OF THE MERIDIAN OF CHESTEBLE-STREET. 

 — THE HOUGHTON-LE-SPRING DISTRICT. 



A and B not recognised. 



C. The Three-quarter Coal, is of very inferior quality, and not work- 

 able to profit at this time. It has been worked anciently on the south 

 banks of the Wear, near to Pensher Staith. 



D and E united, forming the Five quarter Seam. This seam yields 

 Coal, of inferior quality, has been extensively worked in some parts of 

 the district, but is not workable to profit, in other parts. 



F. The Upper, or High Main Coal Seam ; is generally of good 

 second-rate quality, although it is very bad in some parts. It has been 

 extensively worked. 



G. The Maudlin Seam ; is of good second-rate quality, where the 

 seam is found in a perfect state, but it varies so much in thickness, and 

 is so much interstratified with stone bands, that it is not workable in 

 many parts of the district. This is the character of the Maudlin Seam, 

 throughout the whole extent of the Coal-field, under whatever name it 

 is called. It has been extensively worked in the district, and still pro- 

 duces a large supply of Coals. 



H. Tfte Six-quarter Coal ; is not found in the greater part of the dis- 

 trict, and no where in a workable state. 



I. The Low Main Seam ; varies much in thickness and quality, and 

 is nipped out, or has not been deposited in some parts of the district. 

 Where found in perfection, it has been extensively worked, but the Coal 

 is of second-rate quality. 



K. The Hutton Seam ; lies through the whole district, and supplies 

 all the best Coals shipped on the Wear. It is this seam which supplies 

 the Stewart's, Lambton's, and Hetton-Wallsend Coals. It has been 

 extensively worked. 



L, M, N, have not yet been found in a workable state, and 



The Beaumont Seam can hardly be said to be yet known in this 

 district, as it has only been bored to in one or two places, near the 

 banks of the Wear.
