HC Deb 05 February 1951 vol 483 c158W
44. Mr. Osborne

asked the Minister of Fuel and Power what is the estimated average calorific value of the coal raised in the United Kingdom in the years 1938 and 1950, respectively.

Mr. P. Noel-Baker

I regret that there are no national statistics available which show the average calorific value of the coal raised in 1938 and 1950.
