21. Mr. GRENFELLasked the Secretary for Mines if he can give a record, as the result of his inquiry, of the accidents that have happened to private users of anthracite coal which have been 198 attributed to explosives or detonators in the coal sold to customers at home and abroad?
§ Commodore KINGAs a result of inquiries into explosions in anthracite stoves in 1922 and 1923, the owners of anthracite mines changed the type of explosive used. One such explosion occurred in 1924 and one in 1925, but since the latter year no reports of similar explosions have reached my Department or the Home Office.
