The average value of coal, coke and manufactured fuel exported from the United Kingdom during September was 13s. 2-3d. per ton, as compared with 14s. 0-ld. in September 1913, and 12s. 8 4d. in September 1912. The value of fuel exported in the first nine completed months of the present year was 13s. 8 6d. per ton, as compared with 13s. ll*6d. and 12s. 6’2d. per ton in the corresponding periods of 1913 and 1912 respectively. Of the total exports of coal during September, the mean value of the large coal exported was 15s. 0 03d.; through-and-through (unscreened), 12s. 2 5d. ; and small coal, 9s. 10 09d. The average value of all kinds of coal exported was 13s. 0*3d., a decrease of 0*8d. as compared with the previous month. Other- wise divided, it fetched the following:—Steam coal, 13s. l’4d. ; gas coal, 12s. 5’006d. ; anthracite, 16s. l‘8d. ; household, 12s. 9-2d. ; other sorts, 12s. 2-2d. The mean value of the coke exported was 14s. 5-8d. per ton, and of the manufactured fuel 17s. 6-4d. per ton. A meeting of the Mining Institute of Scotland will take place to-morrow (Saturday) at Edinburgh, Three papers are down to be read at the ordinary meeting of the North of England Institute of Mining and Mechanical Engineers at Newcastle on Saturday. The Spanish Government have re-imposed the Customs duties on imported coal. It is reported that during August the coal produc- tion of Austria-Hungary dropped 30 per cent., and that of Germany 50 per cent. The London coal trade for the past week has been very slow. The new price lists from October 1 are with difficulty maintained. Public orders are scarce, and the depots are very short. The financial barrier, though still painfully existent, has improved during the past week. Unfortunately, the full benefit has not been felt by the coal trade owing to the new shipping difficulties which have arisen as a result of the laying of mines in the North Sea by the Admiralty. This action has caused both war risk insurance rates and freight rates to rise. On the Tyne the market is depressed, and there is little tonnage. In Lancashire and Yorkshire matters are a little brighter, trade under the circum- stances being satisfactory. At Cardiff little alteration has taken place since last week. The Scottish coal trade in the west shows further improvement, but that in the east is still poor. The effect of the war upon the export of fuel is plainly evident from the statistics now available,
