It cannot be deemed uninteresting to inquire what are the repositories of coal that can supply the metropolis and the southern counties, when no more can be obtained from the Tyne and the Wear. The only coal-fields of any extent on the eastern side of England, between London and Durham, are those of Derbyshire and those in the west riding of Yorkshire. The Derbyshire coal-field is not of sufficient magnitude to supply, for any long period, more than is required for home consumption, and that of the adjacent counties. There are many valuable beds of coal in the western part of the west riding of Yorkshire which are yet unwrought; but the time is not very distant when they must be put in requisition, to supply the vast demand of that populous manufacturing county, which at present consumes nearly all the produce of its own coal mines. In the midland counties, Staffordshire possesses the nearest coal districts to the metropolis, of any great extent; but such is the immense daily consumption of coal in the iron-furnaces and founderies, that it is generally believed this will be the first of our own coal-fields that will be exhausted. The thirty-feet bed of coal in the Dudley coal-field is of limited extent; and in the present mode of working it, more than two-thirds of the coal is wasted and left in the mine. If we look to Whitehaven or Lancashire, or to any of the minor coal-fields in the west of England, we can derive little hope of their being able to supply London and the southern counties with coal, after the import of coal fails from Northumberland and Durham. We may thus anticipate a period not very remote, when all the English mines of coal and ironstone will be exhausted; and were we disposed to indulge in gloomy forebodings, like the ingenious authoress of the "Last Man," we might draw a melancholy picture of our starving and declining population, and describe some manufacturing patriarch, like the late venerable Richard Reynolds, travelling to see the last expiring English furnace, before he emigrated to distant regions.[1] [1] The late Richard Reynolds, Esq., of Bristol, so distinguished for his unbounded benevolence, was the original proprietor of the great iron-works in Colebrook Dale, Shropshire. Owing, I believe, partly to the exhaustion of the best workable beds of coal and ironstone, and partly to the superior advantages possessed by the iron-founders in South Wales, the works at Colebrook Dale were finally relinquished, a short time before the death of Mr. Reynolds. With a natural attachment to the scenes where he had passed his early years, and to the pursuits by which he had honourably acquired his great wealth, he travelled from Bristol into Shropshire, to be present when the last of his furnaces was extinguished, in a valley where they had been continually burning for more than half a century.
