SECTION OF A COAL MINE. 



117 



The aggregate depth of the Ashby-de-la-Zouch coal-field exceeds 

 two hundred and twenty yards in this part of the coal-field; though, 

 fronri the basin-shaped form of the beds, the lowest, or main coal, 

 rises to the surface at about three miles distance from this pit. In 

 this series we find about one hundred and thirty distinct strata, com- 

 prising ten beds of coal, of which eight, at least, would be consider- 

 ed workable in some countries, and about twenty eight seams of 

 ironstone, and strata containing ironstone. The lowest, or great coal 

 bed, contains coal of different qualities, divided by small partings of 

 clay. Near the middle of the great bed, there is a stratum of coal 

 so hard as to form a firm roof, which enables the miners to work out 

 the lower coal with great advantage : this lower coal is about six feet 

 in thickness. A bed of coal of this thickness, with a strong sound 

 water-tight roof, can be worked with greater ease and less expense 

 than any other, as the men can stand upright, and much less timber 

 is required to support the roof or walls, than in very deep coal beds, 

 like the main Staffordshire coal. When the lower coal is worked
