The demand is good, but supplies are weak. House- holders and merchants alike are anxious to lay in winter stocks, but very little coal is offering. House coals are scarce, and hard steams are largely commandeered for munition use. Small nuts are practically unobtainable, and all kinds of slacks are in strong demand. The seaborne market is firm, and better supplies are coming forward. A quiet tone for prompt business is reported in the Tyne and Wear trade. Most descriptions of coal are easier on the week, and some buyers are inclined to “bear” the market. In Lancashire, the prices of manufactured fuel and shipping coal have lost some of their firmness. Regular supplies have eased the position perceptibly in Yorkshire, and the renewal of contracts is proceeding without difficulty, in spite of the new conditions. The demand for house coal is a salient feature of the abnormal flow of orders in the Midlands. Quotations have become irregular in the restricted amount of business passing in Cardiff. Swansea reports a decline in manu- factured fuel shipments. In East Scotland the easier tendency continues, and in the west prices are for the most part a matter of arrangement. The immediate effect of the limitation scheme regarding coal shipments has been a considerable lowering of freights and pit prices. The central executive committee in London is considering a general scheme for regulating prices and freights for the whole of the Allies’ ports in the Mediterranean. Exports of coal, coke, and manufactured fuel in June aggregated 3,503,955 tons, of the value of £4,751,977. Similar exports amounted to 3,725,423 tons, valued at £3,324,458, and 5,999,417 tons, valued at £4,086,833, in the corresponding months of 1915 and 1914. The average value of coal, coke and manu- factured fuel exported in June was 27s. 14d. per ton, compared with 17s. lOTd. in June 1915, and 13s. 7’4d. in June 1914. The average value during the first six months was 22s. 8’7d. per ton, as com- pared with 16s. 0*4d. and 13s. 10’05d. in the corre- sponding periods of 1915 and 1914. Of the total exports of coal (3,265,698 tons) during June, the mean value of the large coal was 31s. 1 l*2d.; through-and-through (unscreened), 22s. 5*5d.; and small coal, 22s. 0*7d. The average value of all kinds of coal exported was 26s. 9*5d., as compared
