LONDON, FRIDAY, JANUARY 29, 1915. < The Home Secretary gives notice that, on January 15, 1915, he made an Order under section 61 of the Coal Mines .Act, 1911, entitled “The Explo- sives in Coal Mines Order of January 15, 1915,” the effect of which is to add the following explo- sives, viz., “Abelite No. 4,” “A. 2. Monobel,” “ Kynarkite No. 2, “ Victor Powder No. 2,” “ Viking Powder No. 1,” and “ Viking Powder No. 2,” to the permitted explosives named and defined in the First Schedule to the Explosives in Coal Mines Order of September 1, 1913. The London coal market is very short of supplies. Colliery quotations are withdrawn, as in many cases no house coal is available for sale. During the week public prices advanced. The shortage of fuel is causing grave difficulties, but increasing seaborne consignments are anticipated. It would now appear that freight rates have reached their maximum, and that a decline will not long be delayed. During the week the Admiralty commandeered supplies of tonnage for deliverance of coal to France, and this served to further upset the general tonnage situation. Increased attention has been drawn to the shortage of mining labour caused by enlistments ; thus the markets all show signs of restricted output, and prices tend to advance. On the Tyne and Wear the prompt markets are still fettered by the shipping position; the tone, however, is very firm. Inland markets throughout Lancashire, Yorkshire and Derbyshire have but one story to tell—insufficient supplies. Cardiff has been fortunate enough to receive a better service of boats, but the immediate effect on the docks has been to bring about a state of congestion. The position of the Scottish market remains strong, and prices are firm. The provisional committee of users of dyes which has been appointed to confer with the Board of Trade as to a scheme for the establishment of a national dye-making industry on a large scale met on Wednesday and Thursday at the Board of Trade offices. • The committee eventually came to a unanimous decision in favour of the - adoption of a modified scheme for a national undertaking which it is believed will provide for rapid and effective action to meet the present emergency, while capable of future development as opportunity permits. The approval of the Treasury for the revised financial arrangements has been obtained. The movement of Scottish gas authorities to obtain a suspension of the Eight Hours Act has received support from various other quarters. Preliminary tables of fatal accidents in and about mines and quarries in the United Kingdom during 1914 have been issued. The gross total number of separate fatal accidents .at coal mines was 1,173, as compared with 1,220 in the preceding year. Under the Coal Mines Act the gross total number of deaths from accidents was 1,210, or a decrease of 543 compared with the previous year.
