ELSDEN, D.Sc. (Lond.), F.G.S. HUBERT GREENWELL. LONDON, FRIDAY, JANUARY 16, 1914. Fatal accidents in mines under the Coal Mines Act last year numbered 1,210, and the deaths caused thereby, 1,742, as compared with 1,151 accidents and 1,276 deaths in 1912. Explosions of firedamp or coaldust accounted for 461 of the deaths, the deaths from this cause in 1912 being 124; the deaths from falls also rose from 567 to 614, those from shaft accidents' from 71 to 96, and those from miscellaneous causes below ground from 339 to 400. The minutes of the evidence given before the Departmental Committee on Spontaneous Combus- tion of Coal in Mines from July 31 and August 13, 1913, has been issued as a White Paper. The witnesses examined included Dr. W. N. Atkinson and Messrs. J. T. Greensmith, J. Criddle, D. Bailey, J. Gerrard, J. Upton, H. Boss, G. Probert and J. Owen. Meetings in connection with the Mining Associa- tion of Great Britain were held at the Whitehall Booms on Tuesday, the 13th inst., a short report in regard to which will be found in another column. The Coroner’s enquiry into the Senghenydd disaster was concluded on Wednesday. The jury returned a verdict of accidental death. They found that the accident was not due to the neglect of any person, and that the explosion was caused by gas fed by coaldust. As regards the ignition of the gas and the original seat of the explosion, they stated that there was insufficient evidence, but that the pre- ponderance of such pointed to the naked light at the lamp station. They recommended that the lamp station should be placed in the arch-work near the shaft, and that water should be distributed by a spray. The jury were also of opinion that there were not sufficient inspectors of mines in the district. During the week Mr. W- N. Atkinson, divisional inspector of mines for South Wales, gave evidence. In another column will be found a letter which the Home Secretary has sent to the Coroner in reply to criticism made at the inquest that the Home Office had refrained from advancing any theory as to the cause of the disaster. Twelve men were killed in an explosion in Bock Castle Coalmine, near Birmingham (Alabama), U.S.A., on the 10th inst. There were 200 other men at work at the time of the explosion, but they succeeded in effecting their escape. It is believed the explosion was due to coaldust. The special meeting of the executive of the Miners’ Federation of Great Britain, which met on Tuesday and Wednesday, has failed to reach a definite decision on the Chesterfield election difficulty. It
