The pre- vailing hot weather keeps the consumption low. Supplies are coming in very slowly, and the disloca- tion of the railway traffic has been very pronounced. Manufacturing qualities are moving freely, and the export trade is reported better. Small nuts and slacks have been very plentiful, and prices are weakening. Colliery quotations for house coals are still withheld. One by one the barriers which held up the coal trade at the beginning of the war have • been removed, and although the conditions prevailing previous to the outbreak cannot quite be renewed, everything possible to facilitate trade is being done. The reduction in war risks, insurance rates, and also in freight rates have further improved the situation ; indeed, so low have the latter fallen that some shipowners have threatened to lay up ships. To deal with the markets separately: Newcastle con- tinues to show improvement in both prompt and forward business ; the pits also are working slightly better. At Cardiff, too, matters are progressing much more favourably, and the demand in some cases has caused a slight increase in prices. In the Midlands trade is still quiet, though in the Yorkshire market a better enquiry is to be noticed. The market in the East of Scotland shows briskness, whilst that in the West has also improved. The moratorium has been extended to October 4. War risks insurance rates have been reduced from three to two guineas per cent, on cargo shipments. A reduction of a half per cent, in the premium on hulls has also been conceded. The Mining Association of Great Britain and the Board of Trade are acting together in the matter of the shortage of pitwood supplies. Two serious accidents—though fortunately without loss of life—occurred in Durham on Sunday last. At Burnhope colliery five persons were injured by an explosion of gas, whilst in the other case, at the Tursdale Colliery, a fire broke out close to the bottom of the return air shaft causing considerable damage to property.
