the strata at Gosforth on the south side of the great dyke, and 

 at this mine, which is about two miles on the north side of it 

 from Killingworth. The sections of Hartley and Killingworth 

 Collieries (see first series of Geological Transactions, vol. iv. 

 p. 31. and 32.) also serve to throw considerable light on the 

 northern division of this mining field, though the identity of 

 the various coal seams situated to the north and to the south 

 of the dislocation is still a problem unresolved. However, I 

 trust the great professional knowledge of Mr. Buddie, aided 

 by the numerous documents in his possession, will enable him 

 soon to elucidate this obscure but interesting subject.
