Commander HAMILTON BENN
asked the President of the Board of Trade whether he can give the output of coal per man employed in mines in Great Britain for anthracite and bituminous coal, separately; and how this compares with the output by American mines?
§ Mr. BRIDGEMAN
Practically the whole of the anthracite coal is produced in South Wales. The output of anthracite coal per man employed, based on the first six months of 1918, is 207 tons per annum, and of other coal in South Wales 222 tons per annum.
The corresponding figures for the United States for the year 1916 (the latest figures available) are:
Anthracite, 548 tons per person employed, per annum.
Bituminous, 896 tons per person employed, per annum.
The American ton is a net ton of 2,000 lbs.
