asked the Minister of Health whether he is aware that coal can be treated and left smokeless, and weight for weight gives the same heat as raw coal, also that the smoke is condensed into marketable commodities; and whether his Department will frame a scheme for the scientific treatment of raw coal?

I am aware of the scientific facts referred to by the hon. Member, but I am advised that the formulation of a practical scheme for such a treatment of coal must await the solution of engineering problems which have been and are still engaging the active attention of the Fuel Research Board and independent workers.

Will the right hon. Gentleman consult the chief of the Fuel Research Board and ascertain whether he has not seen at work a plant which overcomes all engineering difficulties?

I will make inquiries.

Is the right hon. Gentleman not aware that there is at present on the market smokeless fuel which is regarded as being of distinct advantage to consumers?

That is not the coal referred to in the main question.
