The coal dispute in England has quickened research experiments to* such an extraordinary degree that what might be called the battle of temperatures seems to be going decidedly against the miners (says a London message to the "New York Herald"). Hitherto many by-products of coal have been 'wasted because of the use of coal at - high temperature, but the coming method will be to treat coal at a low j temperature and to extract from it oils ] and sulphaies to be U3ed for fertilising. Va6t developments already are beta;? contemplated at the co lieries. Many , experts say that; it will #ome to pa=3 that the coal mines will produce oil, and the coal residue will be used for ! burning in any grate, and this coal will be smokeless. Londoners who have been very grateful to the striking miners because of the clearness of the atmosphere during the last month when coal could not be obtained, and therefore no smoke clouds were raised, now see clearer than ever before, nnd_ the distant horizon looks good to them. The time may come when London at all times will be smokeless, which means that it will be fogless. One of the most readv followers of the new idea is the King himself, who has given instructions that only smokeless fuel is to be used at Buckingham Palace.
