The Warwickshire Coal-field extends from a point east of Tamworth to a point east 

 of Coventry, about twenty miles from N.W. to S.E. parallel to the Ashby coal tracts. 

 The strata are most productive of coal near the southern extremity, where, by the 

 coming together of two seams, worked separately at Griff, the five-yard seam is 

 worked. The beds are known as the seven-feet coal and rider, slate coal, two yards, 

 lower seam, cannel, and Ell coal. 



YORKSHIRE. Professor John Phillips gives the following mode of classification as 

 the most natural and convenient for the Yorkshire coal : 



Magnesian limestone unconformably covers the coal seams.

seam.

LANCASHIRE. The coal-field of Lancashire occupies an area extending from 

 Macclesfield to Colne, 46 miles, and from Torboch, near Liverpool, to Todmorden, 

 nbont 40 miles. Excluding the millstone grit, its area is about 250 square miles. 

 Heywood. 



In a line through Worsley, Bury, and Burnley to tho limestone shales of Pendlo 

 Hill, we have 36 seams of coal, 10 of them not exceeding 1 foot in thickness, making 

 in all 93 feet of coal. 



The series is divisible into three parts above the millstone grit : 



Upper part, containing a bed of limestone at Ardwick, near Manchester. 



Middle part, containing the greater part of the thick and valuable scams, especially 

 cannel coal of Wigan. 



Lower part, corresponding to the ganister series of Yorkshire.
