(Lond.), F.G.S. HUBEBT GREENWELL, F.S.S., Assoc.M.I.M.E. (At present on Active Service'). LONDON, THURSDAY, APRIL 20, 1916. The London coal trade continues firm. Smalls are in strong demand and steam coals scarce. Prices unchanged. The Tyne and Wear coal trade is practically in a state of suspension, for no appreciable supplies for private trade are available. Prices are still nominal. Tonnage is plentiful, and freights are greatly in favour of charterers. Lancashire, Yorkshire and Cheshire correspondents, in reporting scanty supplies outside contract obligations, throw doubt on the possibility of prices being much lower this summer. Colliery owners in the Cardiff district are still refusing to quote for early shipment. The Scottish trade shows little or no change. The question of the Easter holidays added some- thing to the uncertainties of the coal trade during the past week. South Wales decided on two days. Some other localities will take two days, and subsequent absenteeism is feared. The establishment of a national wages board for miners is one of the proposals under consideration of the executive council of the Miners’ Association. The arguments of Mr. H. P. Houston, M.P., regarding co^l freights, are severely criticised by an Italian contemporary. Discussions regarding the limitation of freights to Italy and France are taking place. The Board of Customs, after withdrawing its new regulation regarding the time allowance for coal shipments, has reinstated it. The Appeal Court decided against the railway companies regarding the charges for carrying coal from the Glen Rhondda, and Corrwg Collieries, Glamorgan. A paper on 11 Some Work in the Kent Coalfield” was read by Mr. F. Meachem at a meeting of the South Staffordshire and Warwickshire Institute of Mining Engineers on Monday. The coal export trade at the present Shipping time presents many difficult problems, and the mostly due to the war, and directly Export Coal resulting from an insufficiency of Trade. tonnage to meet the national requirements. Last week, we called attention to the Italian coal trade, and on previous occasions we have dealt at some length with the position in France. In the latter country a vigorous effort is being made to meet the situation, and a Bill has already been adopted to limit the price of coal. ! What, however, is of greater interest to exporters is the rumour that a movement is on foot between the
