A proposal is on foot in the Midland coalfields to establish a fund for the relief of members of rescue brigades who become incapacitated either in rescue work or whilst training. To-morrow (Saturday) the conference on mining education, which was adjourned from December 20, will be resumed at Cardiff. A scheme for securing the co-ordination of mining instruction throughout the South Wales coalfield is under consideration. It has been suggested that a conference of South Wales miners should be held to discuss the question of electricity in mines. The fourth part of the report of the Chief Inspector of Mines and Quarries for 1911, relating to colonial and foreign statistics has been issued as a Blue Book [Cd. 7217]. The number of persons engaged in mining and quarrying at home and abroad reached nearly 6 J-millions, of which total nearly one-fifth were employed in the United Kingdom, and were thus one-third in the British Empire. More than half of the total number were employed in getting coal ; Great Britain employing nearly 1,050,000, the United States over 722,000, Germany nearly 701,000, France over 200,000, Kussia (1909), 169,000, Belgium 144,000, Austria 129,000, and India 116,000. The total output of coal was nearly 1,187 million metric tons, the value of which is estimated at 435 million pounds. The chief producer was the United States with 450,169,000 metric tons, Great Britain came next with 276,255,000 tons, and Germany was third with 234,521,000. The death- rate per 1,000 persons employed was in the United Kingdom IT7, and for the British Empire 1*25, Austria 1'27, Belgium IT4, France 1’08, Japan 3*42, Germany 2-08, and the United States 3*55. The death-rate in foreign countries generally was 2’51. The Home Office has addressed a circular letter to owners drawing attention to the recommendations of the Explosions in Mines Committee, as contained in their Fifth Report, and stating that it will be necessary to issue regulations. Prior to this, the Home Office ask for suggestions from owners, which are to be sent in before the end of February. A conference was held at the Mansion House on Monday, the Lord Mayor presiding, to discuss the expediency of establishing a national fund for the relief of distress due to colliery accidents. It was decided to appoint a committee, which should consider the matter and report upon it at a subsequent meeting. A full report of the meeting will be found elsewhere in these columns. The Home Office enquiry into the Senghenydd disaster will be resumed at Cardiff on Tuesday next
