The London market is well supplied with all qualities of household fuel, and the demand is slackening. Steam coals and hard cobbles continue scarce. Seaborne gas coals have fallen off. Business on the Tyne and Wear is still curtailed by inadequate tonnage. Steam coal collieries are nearly all fully booked and well stemmed, but the gas coal pits cannot cope with the demand unless vessels are more plentiful. The bunker market is dull. Trade in all kinds of fuel is fairly active in Lancashire, and supplies which reach the market are easily sold at full figures. House coal and slack are scarce, and coking slacks are difficult to obtain in Yorkshire. Some of the collieries there are crushing soft nuts to supply coke-making material. Business in Cardiff is very quiet in all departments with the exception of house and gas coals. The position in Scotland appears to be fairly satisfactory, and the outlook is considered promising. Anthracite is plentiful in Swansea, and rubbly culm and duff are freely, offered. Patent fuel is firm. Freights are unaltered and the business is unim- portant owing to meagre offerings of tonnage. Coastwise chartering is quiet. The Coal Controller informed a deputation of the South Wales Miners’ Federation that he would con- sider the proposal for a uniform working week of five days. A paper on “ Wastes, Shales, Lower Grades of Small Coal: their Nature, Recovery and Use for Oil and Power Purposes,” by Mr. J. Drummond Paton, will be read at a meeting of the Manchester Geo- logical and Mining Society, 5, John Dalton-street, Manchester, on March 12. commencing at 4 pm. A paper on “ Some Useful Instruments for Colliery Power Plants,” by Mr. H. W. Ravenshaw, will be read at a meeting of the Midland Institute of Mining, Civil and Mechanical Engineers, at the Danum Hotel, Doncaster, to-morrow (Saturday), commencing at 3 p.m. Everyone is interested in the sub- Alcohol and ject of the physiological action of Work. alcohol on the human organism, and most people have definite notions upon the subject, based more or less upon their individual idiosyncrasies. But few are aware of the actual state of scientific knowledge respecting it. A cordial welcome, therefore, should be given to a report just issued by the Advisory Committee appointed by the Central Control Board (Liquor Traffic) in November 1916 to consider the matter. This Committee has so far confined its attention to an examination of past investigations, with the view of determining what scientific evidence there may be respecting the physiological action of alcohol and its effects upon health and industrial efficiency. This is, of course, the only way to begin a scientific investi- gation ; and more especially is it necessary in this case, because the whole matter has been befogged by the irresponsible dogmatisms of pronounced faddists of every shade of opiniativeness. Lord D’Abernon’s Committee has made a dispas- sionate survey of what is actually known upon this matter, and precious little it proves to be. Mainly what is known concerns rather the abuse than the use of alcohol. It is this aspect of the question which has made it a national question in every civilised country. In the year before the war a strong and authoritative international commission for the scientific study of alcohol was set up in Paris, but its labours were necessarily suspended by the grave events which followed its inception. The Advisory Committee of the Central Control Board is bent upon pursuing the subject forthwith, and we are glad to note that experimental research is being already carried out in order to supplement some of the imperfections of previous investigations. Thus, much of the laboratory work hitherto done in this connection, and upon which various conclusions have been founded, has been conducted with solutions of ethyl alcohol in water. Obviously, this is not the same thing as using actual alcoholic beverages such as are employed in common life. It is satisfactory, therefore, to find that experiments have lately been carried out by Dr. Edward Mellanby which promise to throw light upon the differences exhibited by various alcoholic beverages as compared with the pure chemical substance, C2H60, in various degrees of dilution. Apart from the scientific side, even the statistical aspect of the alcohol problem is sadly deficient. In the comparative mortality tables compiled for the period 1910-1912 by Dr. T. H. C. Stevenson, Superintendent of Statistics, Somerset House, but little light is shed upon the subject, for the reason that the ordinary system of certifying causes of death is not precise enough to enable the influence of alcoholism to be measured. Coal miners, as judged by this evidence, show an excellent record. Out of 727 deaths from all causes, within the above period, only three are attributed to alcoholism, and 13 to a combination of alcoholism and liver diseases. Thus, while in the case of dock labourers the comparative mortality figure for alcoholism is more than three times that for the general male population, the corresponding figure for coal miners is less than half the same standard, and is, in fact, one of the lowest on the list. The Committee, in their report, comment upon this fact in the following terms : “ The miner’s task,” they say, “involves muscular effort which in
