The London coal trade has at last begun to show signs of returning activity. The increasing export trade has given confidence to buyers, and the volume of trade doing is increasing. The delivery trade, however, continues weak, but factors and merchants are buying more freely for stock. Manufacturing qualities are in good demand, and kitchen coal and bakers’ nuts are also moving better. Gas coals, although very low in price, are improving, but slacks and small nuts are still weak and plentiful. The seaborne market shows no change. The coal markets in the provinces have benefited by the cooler weather which has prevailed during the week. On the other hand, too, there is an increasing enquiry from friendly and neutral countries. Financial conditions are still prejudicial to business, and this disadvantage has been severely felt at Cardiff, where little new business has taken place, the market in general being dull and void of special feature. On' the Tyne, whilst the volume of business does not appear to have greatly expanded, the undertone of the market is good. The West Yorkshire market has become depressed, but that in the South shows a slight improvement; the reduction of output and a fair demand has served the purpose of steadying the market. In Lancashire the house coal trade has improved owing to the colder weather. The Scottish coal trade may be said to have changed little, and remains very quiet. It is officially announced that on October 4 the moratorium will be partially ended, and that on November 4 the general moratorium will also be terminated. The Admiralty have now notified the South Wales Coal Conciliation Board that the Government do not require collieries to work an extra hour per day. The South Metropolitan Gas Company has increased the price of its gas owing to the continued high price of coal. The death has taken place during the week of two men intimately connected with the coal industry— viz., Mr. Richard Cory, senior director of Messrs. Cory Bros and Company Limited ; and Mr. Thomas Bell, of Messrs. Pyman, Bell and Co. It is announced that the Portuguese railway contract for steam coal has come to this country. This is the first coal contract which has been diverted from Germany by the war.
