inches of coal and bands, 

 thickness of coal and bands 

 (11 feet, Oh inch), thus bear- 

 ing out Professor David's 

 opinion that the seam, being 

 somewhat perished in his 

 shaft, would probably be 

 found to have a greater 

 thickness.* There is a small 

 band of white clay just be- 

 low the top seam. The two 

 seams at this point are about 

 40 feet apart, and their dip 

 is N.47°W. at 24°.

This seam is the 

 equivalent of the top" 

 seam further north at 

 the Rothbury Colliery. 

 It does not quite attain 

 the thickness of that 

 seam, but, when ex- 

 posed to the weather, 

 the same yellow stain 

 and sulphur-deposit are 

 noted as at the Col- 

 liery. There is also a 

 slight smell of H^S in
