The London coal trade continues fairly brisk for all kinds of manufacturing fuel, but slow for house- hold qualities. Public prices were reduced Is. per ton best Wallsend, and 2s. per ton on all other sorts, on Monday last. The usual pre-holiday demand for coal has again made itself felt, and prices have continued high. It is expected, however, that values after Easter will resume a more normal level. Further reductions in freight rates have taken place, tonnage being in good supply. On the Tyne and Wear the prompt markets are firm, but business is practically at a standstill owing to loading turns being congested. The Lancashire market still bemoans a shortage of supplies, and the same may be said of the Yorkshire markets owing to absentees restricting the output. The enquiry in both districts is brisk. The Derby- shire coal trade is stronger than ever, and prices are still moving upwards. At Cardiff, little change has taken place, except that the market is firmer, and Admiralty demands are more pressing. The Scottish coal trade continues active, and prices are firm. In the Hail way and Canal Commission Court yesterday (Wednesday), the Denaby and Cadeby Colliery Company applied for an order on the Great Central Bailway Company to give reasonable facilities for the carriage of coal. Eventually the colliery company undertook to provide the railway company with coal at a reasonable price without prejudice to an enquiry as to whether the price was the properone; and the latter on their part promised to do their utmost to deal with the trucks that had accumulated. The Court decided to make no order in the circumstances The railway com- pany should- appeal at the earliest moment, and the trial of the action would take place as soon as possible.
