§ The SECRETARY for MINES (Commodore Douglas King)
The number of mines in Cornwall at which dressed tin ore was produced was 29 in 1919, 23 in 1920 and 11 in 1927. In each year there were in addition a number of mines at which only prospecting or development work was in progress.
§ Commodore KING
No, Sir, but I think I could supply the information if the hon. Member put down a question.
