HC Deb 08 May 1950 vol 475 c1W
36. Mr. R. S. Hudson

asked the Minister of Fuel and Power whether the current figures published his Department for output per manshift overall in the coal mines refer to coal raised and weighed; and whether the figures for 1939 were computed on a similar basis.

Mr. P. Noel-Baker

The figures of output per manshift in the coal mines published by my Department in 1939 were not for coal raised and weighed, but for saleable coal. So are the figures of output par manshift which are published today.
