A short distance to the North-East of this, another nearly circular

 the bed is from eight to ten feet thick, while within less than twenty 

 feet it dwindles down to one foot. At the Southern end of the croom 

 a fault or slip, the walls of which are very irregular, cuts it off altogether. 

 This break crosses the rocks from North-East by East to South-West 

 by West. The same nummulitic limestone as before is here seen at 

 about the same distance below the coal, eighteen to twenty feet. The 

 accompanying sketch (Fig. 15) represents the mode of occurrence of

The most extensive workings as yet opened are situated Eastward 

 of this, on the side of a deep croom facing to the East (at e on plan). 

 Here the coal has been excavated in five headings, which have been 

 carried in some distance (about 9 fathoms). The coal is about seven 

 feet thick and of good quality : but it varies, and in one of the headings
