§ 60. Mr. D. GRENFELL
asked the Secretary for Mines the number of pneumatic boring machines used for boring stone in the South Wales coalfield and the number in use in the United Kingdom?
§ The SECRETARY for MINES (Mr. Ernest Brown)
The figures for 1932, which are the latest available, show a total of 5,730 pneumatic drills in use at mines under the Coal Mines Act: 1,073 of these were in use in South Wales. I regret I cannot give any figures as to the extent to which these drills are used in the boring of stone or otherwise.
