The whole area occupied by the Potteries Coal Field is of small extent, though of 



great mineral resources. It is of triangular form, the northern apex lying near Congleton, 



the eastern at Lohgton, and the western angle a little west of Keel. Its greatest length 



is about 12 miles, and its width about 8 miles. 



* In Mr Ward's Geology of the Coal Field this division is called the Lower Thick Coal Measures, but as the rocks 

 included in this group are evidently the equivalents of the Lower Coal Measures of other Coal Fields, I have omitted the 

 word " Thick," as tending to create confusion. 



t In regard to some fossils found in " a bed of grey shaley marl, or ' clutch,' lying a few feet above the Gin Mine, 

 or Golden Twist Coal," Mr Ward states (loc. cit., p. 42) that Mr John Yodng, F.G.S., Glasgow, informed him "that 

 the specimens in the list agree closely with those found in the Upper Coal Measures of Scotland." It must be distinctly 

 stated here that the term Upper Coal Measures of Scotland, as used by Mr Young, is only of local application, and does 

 not at all correspond to tlie Upper Coal Measures of Britain. The rocks called Upper Coal Measures of Scotland are only 

 the Upper Series of the Lower Coal Measures of Britain.
