The cold weather has largely stimulated the demand on the London coal market, and public orders are again very plentiful. The tonnage coming forward is small. Steam coals are exceedingly short. The Northumberland steam coal pits are overrun with prompt orders, and best and second screened sorts are in strong demand. The market is firm. The demand for almost every sort of fuel is increasing in Durham, and the present week means full work in both counties. Very little house coal is on the market in Lancashire, but the extreme pressure is over. Excepting common slack the demand for industrial fuel is good. The calling up of miners accounts for the shortage in Yorkshire, and all descriptions are in demand. The tone in South Wales is very firm. Superior quality steams have been obtainable for ordinary commercial purposes, and lower grade large coals have been in demand. Tonnage is coming forward satisfactorily. Trade in Scotland is fairly active all round, and shipments are of a substantial character. Business in anthracite is dull in South Wales, and large sorts are plentiful. Machine-made kinds, especially cobbles and nuts, are easily obtainable. Outward chartering is on a small scale. Most of the fixtures on the north-east coast are for Scandi- navia, and in South Wales the transactions are for French Atlantic ports. An official notice has been issued, to the effect that it is not proposed at present to call up for service, or even for medical examination, men of the new military age who are registered as engaged in certain occupations including mines, railways, and transport. The Workmen’s Section of the Coal Conciliation Board for England and Wales met on Wednesday and decided to submit the new wages proposals to the workmen employed in the various areas before opening negotiations with the coalowners. A paper on “ High-Speed Internal-Combustion Engines,” by Mr. H. R. Ricardo, will be read at a meeting of the North-East Coast Institution of
