Joint Editors— J. V. ELSDEN, D.Sc. (Lond.), F.G.S. HUBEBT GBEENWELL, F.S.S., Assoc.M.I.M.E. LONDON, FRIDAY SEPTEMBER 11, 1914, The London coal trade has been very quiet during the week. The railway dislocation has improved, and both loaded and empty wagons have been dealt with in greater regularity. Very little new business has been done, but the arrears of old orders have been cleared. The export trade is seriously crippled, and although the demand is fairly strong, steamers are afraid to venture, and the home markets are becoming congested. The hot weather keeps the house coal markets slow, and manufacturing qualities are very irregular. The trade of the Tyne has been badly affected by the mine casualties in the North Sea and the unsatisfactory status of foreign exchange. Bunkers are in some request. The West Yorkshire house coal trade is quiet, although deliveries of best sorts are in arrears. In South Yorkshire the Doncaster races have interfered with the working of the collieries, but the demand for steam coal is expanding. Slacks and house coals are slow. Coke is stronger. In Lancashire broken time is still the rule. The Scottish coal trade continues dull. In South Wales trade has almost reassumed normal conditions, except that the pits are in need of labour. Small coals are weak. Coke is in better odour. The average value of coal, coke and manufactured fuel exported from the United Kingdom in August was 13s. 3-Id. per ton, as compared with 13s. ll’6d. in August 1913, and 12s. 7 5d. in August 1912. The value of fuel exported in the first eight completed months of the present year was 13s. 9 2d. per ton, as compared with 13s. 11-6d. and 12s. 6 9d. per ton in the corresponding periods of 1913 and 1912 respectively. Of the total exports of coal during August, the mean value of the large coal exported was 15s. 0 3d.; through-and-through (unscreened) 12s. 13d. ; and small coal 10s. 52d. The average value of all kinds of coal exported was 13s. bld. Otherwise divided, it fetched the following: — Steam coal, 13s. 4’8d.; gas coal, 12s. 3’8d.; anthracite, 15s. 6d.; household, 12s. 9-Id. ; other sorts, Ils. 7-3d. The mean value of the coke exported was 15s. 6 9d., and of the manufactured fuel 17s. 2*9d. per ton. The Home Secretary gives notice that, on August 29, 1914, he made an Order under section 61 of the Coal
