C.—COAL MEASURES.—The grit is succeeded eastwards by 
the coal measures. The lower beds form a strip of varying width 
on the west of the true coal measures. They consist of varied 
sandstones, shales, fireclays, and a few thin coal seams, and above 
them on the east we reach the middle and upper coal measures 
extending to the County boundary, and to a line drawn north 
and south by Bolsover, and southward to a line south of Stanley, 
Dale, Stanton, and just above Sandiacre. In addition to this 
east cential coal region there are some patches of lower coal 
measures west of the Peak, one close to the County boundary 
west of Hayfield, a second extending from Ottersett Moor to 
Fernilee, and a very small piece at the top of Goyt’s Clough. 
There is also a small area of coal measures south of the Trent, 
being an extension of the Leicestershire coalfield, and which 
runs up here to Church Gresley, Swadlincote, Newhall, and 
Hartshorn, between Southwood and Scaddows near Calke, and 
a small patch between Ingleby and Robin Wood.
