asked the Secretary for Mines whether, on their recent visit to the Experimental Station at Greenwich, the members of the Royal Commission on the Coal Industry inspected any processes of low-temperature carbonisation?

Yes. Sir. The members of the Royal Commission at their recent visit to His Majesty's Fuel Research Station, were shown all the plant at the station and the work in progress. This included the experimental retorts for low-temperature carbonisation described in the Report of the Fuel Research Board for the period ended 31st December, 1924, and the Report of the Committee for Scientific and Industrial Research for the year 1924–25 (Cmd. 2491).
