asked the Secretary for Mines what methods are employed in driving hard headings in the anthracite district of South Wales; what means of protection is afforded the men against the dust; and whether silicosis is increasing in this district?

The danger of silicosis in work of this character arises from the use of percussive drills in sandstone or other highly silicious rock; and under these conditions protection against the dust is afforded by the compulsory use of water or of a mechanical dust trap. I have no reason to think that silicosis is increasing in the anthracite district, and hope, on the contrary, that these preventive measures will check it.
