asked the Secretary for Mines the amount of the increase in the price of coal commercially disposable between January, 1936, and June, 1938; and how much of the increase per ton was due to wages costs?

The estimated proceeds per ton of coal disposable commercially in Great Britain in January, 1936, were 14s. 11d. and in June, 1938, 17s. 1d.; corresponding wages costs were 8s. 11d. and 10s. 11d. respectively.

Will the hon. and gallant Gentleman see that publicity is given to the latter figure, as it conflicts

I am sure that my hon. Friend will assist in that publicity.

Can the Minister supply any information showing the difference in price between industrial coal and household coal?

No, Sir, I have not been asked that question.

Can the Minister say whether the figures he gives are based upon the price of coal at the pit-head, whereas the figures given by the ex-president of the Miners' Federation relate to the price at which it is disposed of to consumers?

I really cannot go into statements made by other people outside the House. I am answering the question on the Paper.

If the Secretary for Mines is going to give this information, will he also give the difference between the numbers of shareholders in the industry and the numbers of mine-workers?
