Coal-cutting machines.
Among various improvements, which may tend to reduce the price of coal, we may look with confidence to the increased use of coal-cutting machinery as a substitute for manual labour; and to the discovery of methods by which the consumption of fuel may be reduced. The experiments, which have been tried with the machines invented by Captain Beaumont, R.E., and others, have been eminently satisfactory; and these machines are now being made in large numbers in Glasgow and Birmingham.
