The faults over these moor lands usually run from north- 

 east to south-west; one at Hagden throws up the strata 54 

 feet on the south side. 



This Main Coal was worked some years ago, on high moor- 

 land, at Lemmington, five miles southward of Bannamoor, 

 at a depth of from 120 to 160 feet below the surface. It is 

 there from 2 feet 2 inches to 2 feet 7 inches thick, with a 

 stoney band of 2 inches. Thin beds of limestone are in the 

 section, amounting in all to about 4^ feet ; but connected 

 with them are fossiliferous shales of some interest, containing 

 in the under layers such marine organisms as Orthoceras 

 cylindraceum (Flem.), Bellerophon hiulcus, (Phil.), Pleuro- 

 tomaria sulcatula, (Phil.), Aviculo-pecten duplicostatus and 

 segregatus, (McCoy.), and very large specimens of Lingula 

 squamiformis, (Phil.), with the shell well preserved, and 

 showing the muscular and pallial impressions of this Brachi- 

 opod ; in the upper layers are Lepidodendra and stems of 

 reed-like plants; indicating the same transition from marine 

 to estuarine or fresh water conditions as are seen in the Budle 

 and Lammerton shales. The strata here are much broken 

 by faults, and dip at a high angle in various directions, but 

 generally towards the east. 



Different names are given to the same coal in different 

 localities ; but it is sometimes difiicult to identify their same- 

 ness, because the coals vary in quality, and there is, too, a 

 difference in the thickness of the intervening strata in differ- 

 ent parts of the coal-field. It seems, however, pretty certain 

 that the Main Coal at Eglingham is the same as the Cancer 

 Coal of the Berwick district ; at Etal and Ford it is called the 

 Main Coal. It is probable, too, that the Craw Coal is the 

 equivalent of the Scremerston Main or Black Hill Seam, for 

 in both there are nodules of sulphate of iron which deterior-
