SOUTH CROFTY
Question in House of Commons
The conditions prevailing in the South Crofty Tin Mine, Carn Brea, were the subject of a question in the House of Commons on Thursday by Mr. E.P. Smith (Con., Ashford).
He asked the Minister of Labour what steps he was taking to alleviate them and whether until such appropriate action has been taken he would stop drafting into this mine men who had not previously worked underground.
Mr. Bevan replied that safety in mines was a matter for the Ministry of Fuel and Power. The production of tin at home for essential war purposes was of first importance, and he knew of no reason that would justify restricting the supply of labour to South Crofty Mine.
Mr. E.P. Smith further asked whether men accustomed to working in conditions where fresh air was plentiful when drafted to working underground in their mine found the conditions so bad that they were unable to work. Mr. Bevan replied that if conditions were so bad as Mr. Smith suggested he would consult with Maj. Lloyd George on the subject.
