Of the hundred and odd million tons of coal which we in this country burn in the course of a year, about 20,000,000 tons are thrown on our house fires; 30,000,000 tons find their way into our blast furnaces, or are otherwise used in the smelting and manufacture of metals; about 48,000,000 are burnt under steam boilers; 6,000,000 are used in gas-making; while the remainder is consumed in potteries, glass works, brick and lime kilns, chemical works, and other sundries which I need not speak of.
Splint or Hard Coal, 83 per cent.; Cannel, Candle or Parrott Coal, 84 per cent.; Cherry or Soft Coal, 85 per cent.; Common Bituminous, or Caking Coal, 88 per cent.; Anthracite, Blind Coal, Culm, Glance, or Stone Coal, from South Wales, 93 per cent. As far as the gas-making properties of the first three are concerned, the relative proportions of carbon and volatile products are much the same.
