HUBERT GREENWELL, F.S.S. LONDON, FRIDAY, FEBRUARY 13, 1914 The London coal market continues exceedingly dull. Household qualities are very difficult to sell, and most merchants are hampered with an overplus of loaded wagons. Factors are holding aloof from buying unless at very low rates. Very few collieries have yet started issuing current price lists, the bulk of the trade being done at special rates. Seaborne prices are unaltered. The prompt market at New- castle is very quiet, and the Wear market is also rather easy. In Lancashire and Yorkshire, the milder weather has caused a slackening in the demand. A steady tone prevails in Derbyshire, whilst at Cardiff there is now more firmness than hitherto, despite serious dock congestion. The demand in Scotland continues steady. Lord Charles Beresford is to ask the First Lord of the Admiralty if he can state how many ships of all classes, built and building for the Navy, are fitted or to be fitted for burning oil fuel only ; how many ships are to be fitted for burning oil and coal; what are the names of the vessels under each specification ; and what is the maximum oil capacity for each ship. The exports of coal, coke, and manufactured fuel from the United Kingdom during the first month of the year amounted to 6,088,971 tons, with a value of £4,295,693, thus showing a slight decrease as com- pared with the corresponding month of the previous year, when 6,374,152 tons were exported, valued at £4,344,303. The totals for January 1912 were: exports 5,683,978 tons, value £3,422,044.
