§ Brigadier Rayner
asked the Minister of Town and Country Planning what are the acreages on which clay mining takes place, or is contemplated, in Devonshire and Cornwall.

About 1,700 acres are now used for pits, plant and waste tips, and approximately 2,000 acres are taken up by pits and waste tips not at present in use. The area of future workings is now under consideration.
