224 Mr. Buddle's Synopsis of the Newcastle Coal Field. 



EIVER WEAR SUB-DIVISION WEST OF THE MERIDIAN OF CHESTER-LE-STREET. 



— PELTON DISTRICT. 



A and B cropped out. 



C. The Shield Ratio Seam ; lies through a considerable part of the dis- 

 trict, and varies greatly in quality ; it is only worked in Beamish Col- 

 liery at present. 



D and E united, forming the Five-quarter Seam, lies through all 

 the district, is variable in quality, but generally yields good second-rate 

 Coals. Has been extensively worked. 



F. The Main Coal, or Brass-thill. This seam lies through the greater 

 part of the district ; the Coal is of second-rate quality, and has been 

 extensively worked. 



G. The Maudlin Seam ; is very uncertain in point of thickness and 

 quality, and has been little worked. 



H. Not found. 



I. The Low Main Coal ; extends through the whole district ; is an 

 inferior seam, and is not at present worked for sea-sale. 



K. The Hutton Seam. This seam extends through the whole dis- 

 trict, but has only been partially wrought, as the Coal is tender and 

 works small. In some parts it is so interstratified with Stone, Slate, and 

 bad Coal, as not to be workable to profit. 



L, M, N, O, P, Q, R, S, not yet explored. 



Note. — The Three-quarter, Five-quarter, and Six-quarter Seams, de- 

 rive their names from their being respectively 3, 5, and 6 quarters of a 

 yard, or 27, 45, and 54 inches thick. A quarter of a yard being the 

 ancient standard of measure used by the Newcastle colliers.
