March 20, 191i. THE COLLIERY GUARDIAN. 633 A new Order, entitled the Safety Lamps Order of March 9, 1914, amending the previous one of August 26, 1913, has been made by the Home Secretary. The annual dinner of the Institution of Mining and Metallurgy was held at the Savoy Hotel on Thursday, 12th inst. Mr. Churchill, on Tuesday, presented a statement of the Chairman of the Royal Commission on Ruel and Engines, showing the advantages attaching to the use of oil as a substitute for coal for naval purposes. A report has been issued by the Board of Trade [Cd. 7283] which gives some interesting informa- tion regarding the progress of profit-sharing and labour co-partnership in other countries. The North Wales miners have resolved to take a ballot on the dispute of fitters’ wages, which is at the present time the subject of an appeal before the House of Lords. Notices if given would affect upwards cf 10,000 men. A ballot has been taken throughout the South Wales coalfield on the question of increasing the -contributions to the Federation from Is. per month to Is. 4d. The executive council consider such an increase necessary in order to cope with new develop- ments. As was expected, the Yorkshire Miners’ Association •decided to hand in notices in order to enforce their interpretation of the present minimum wage. The notices, numbering about 170,000, have now been handed in. The difficulty was discussed at the meeting of the executive of the Miners’ Federation •on Wednesday, who decided to ask the conference to .await the result of the meeting of the English ‘Conciliation Board to-day (Friday) before reaching a .final decision. At a conference at Manchester on Monday between representatives of the Lancashire and Cheshire Miners’ Federation and the colliery owners, a minimum scale of wages for surface workers was agreed upon. The minimum ranges from Is. 7d. for boys under 14 years, to 4s. 7d. for workers of 21 years and over. Weekly averages of the minimum of all classes of miners were agreed to instead of fortnightly, as at present. It is officially announced that the Miners’ Federa- tion have withdrawn their appeal in the case of Blackledge v. Eames, which affects the rights of miners with reference to the appointment of check- weighmen. The case, which arose out of a dispute regarding the appointment of Mr. Seth Blackledge as checkweighman at the Maypole Colliery, was tried by the Wigan magistrates, who decided that two shafts did not constitute separate and distinct mines. The Milroy lectures delivered by Hygiene in Dr. Frank Shufelebotham before Coalmines, the Royal College of Physicians, which have appeared in our columns in an abridged form, deserve the widest publicity. The lack of any systematic study of occupational disease in this country is a reproach that cannot easily be met, when we remember that there are funds and organi- sations in plenty for the investigation of tropical diseases that have a remoter bearing upon social efficiency. The author of these lectures lays the blame for this neglect in part on the medical profession. Indus- trial diseases, he says, have been neglected in the medical schools and by the leaders of the profession, and there are thousands of medical men working in the industrial districts of England who have never received any training in the medical schools on the diseases which they may be called upon at a moment’s notice to diagnose and to treat. Under such circum- stances, their experience must be gained at the expense of the patient, and—we may add—they frequently become the dupes of the skilful malingerer. It should be remembered, however, that industrial hygiene is a subject to be approached with the utmost discrimination. Whilst it is impossible to condone the ostrich-like policy of denying relationship between industry and disease, a too sedulous enthusiasm may •often lead to dangerous extremes. It is a remark- able fact that several of the scheduled diseases were practically unheard of until the present Workmen’s Compensation Act was passed. Probably the argu- ment that the pecuniary inducement has been responsible for the increased number of cases is only partially true. Dr. Shufelebotham points out that miners are peculiarly subject to nervous com- plaints, and that insignificant physical injuries, to which miners are naturally liable, frequently result in neurasthenia of a pronounced type. Among people of a nervous type, the implied imminence of certain special ailments may actually induce them. It is like putting a medical work in the hands of the layman; he immediately thinks that he is assailed by every disease in the book. Again, whilst we are not prepared to dissent from the proposition that, where the events of a man’s employment have caused him to lose his wages, he should be compensated for such losses, it is also true that repeated breaks in a man’s labour may actually evoke maladies that were dormant or non-existent so long as he continued at work. Every time the furnace is damped down it means loss of energy when the time comes for blowing-in again. We are only speaking of the coalmining industry, and it cannot be too often repeated that this industry, which to some people seems so unnatural and so hazardous, in reality possesses an excellent record. As Dr. Chauvet, of Paris, says: “If the miner for some hours is deprived of the benefit of light, on the other hand he knows nothing of intemperate weather nor of cold. He works below ground in a supportable temperature that is nearly equal at all seasons. Protected from microbe-bearing dusts and corrosive vapours, he has no fear of industrial poisoning, and the sanitary conditions in which he labours are far better than those surrounding the work of glassmakers, quarry men, chemical workers, and many others.” This, no doubt, is only true in a general and comparative sense. The whole burden of Dr. Shufelebotham’s lectures is to point out that coal- mining, notwithstanding the fact that the general health of the workman is excellent, has its special dangers and its special diseases. That is a fact that cannot be ignored, and we think there is a greater likelihood of these dangers being eliminated if their nature is understood and the study of their causation and treatment is left in the hands of those qualified to deal with them. The owners of collieries have certainly done their share to promote the safety and health of the workmen, and, if some of the curative legislation of the past has not only failed in its object, but has actually induced other dangers, it has been largely due to the fact that, whilst experience has suggested remedies, it has been left to amateurs to dictate them in the end. Over and above all this is the error that propriety can be enforced by legislation. As Dr. Shufelebotham observes, “the occurrence of accidents and the prevalence of disease peculiar to the coalminer will not depend altogether upon legislation.” Of much greater importance is the human factor. To take a typical instance: although so many diseases are scheduled under the Workmen’s Compensation Act as being peculiar to coalminers, by far the most serious cause of mortality in the mining community, apart from accidents, is one that has nothing whatever to do with the occupation—we refer to the high rate of infantile mortality in colliery districts. We can only refer here to a few of the points raised by Dr. Shufelebotham. Of these his sugges- tion that a few beds should always be provided at collieries is one well worthy of attention. At Senghenydd, it appears, seven of the men rescued from the pit had to be sent to Cardiff Infirmary, distant 11 miles away, with the result that one died on the way, and only one of the remaining six survived. When pithead baths become general it would not seem to be impracticable to provide for a few portable bedsteads that could be erected in the building. At the Maries Colliery, in the Pas-de- Calais, a hospital is provided right at the pithead, and several of the new collieries in South Yorkshire are proceeding on the same lines. Measures of this sort are sometimes less costly than insurance. Of special interest are Dr. Shufelebotham’s remarks on the use of stonedust. We think he is right in advising caution. He points out that Dr. Beattie’s experiments on guinea pigs, upon which so much argument has been based, cannot be regarded as conclusive, as they were entirely different from the slow and regular inhalation of dust which would occur in the case of a miner. There would seem to be no safe method, indeed, of ascertaining with accuracy the effect of any particular dust upon a man under actual conditions, and this should make us hesitate before any risk is taken on a large scale that might result in wholesale injury to the health of very large numbers of men. The lecturer dealt at length with all the scheduled diseases, and colliery owners will note with mixed feelings that he suggests the addition of a new disease. Dr. Shufelebotham’s tozir de force is the discovery of a new ailment—new, at least, so far as this country is concerned, for we seem to remember an account at the Brussels Congress in 1908 of very similar conditions. Miner’s itch or miner’s rash is a combination of erythema and boils, which in some pits has incapacitated considerable numbers of work- men, and it is an interesting fact that the disease has been found only in hot bituminous seams. In attempting to arrive at the cause, Dr. Shuefle- botham points out that in such conditions there may be to some slight extent continual, though slow, distillation of the bituminous coal with the formation of not exactly coal-tar products, but, at all events, bodies resulting from the decomposition of the coal. This suggests an affection somewhat similar to the epitheliomatous cancer to which briquette-makers are subject, due to certain ingredients in the pitch used as a binding agent. We are steadily approaching to a knowledge of the true nature of these substances, and it will be interesting to find what relation, if any, this miners’ skin affection bears to the pitch warts. Dr. Shufelebotham also suggests that mechanical irritation of the coal- dust may be enhanced by profuse perspiration, and he also mentions that he has found the same bacteria in the coaldust and in the pus extracted from the boils; or, again, the trouble may be due to the oxidation of sulphate of iron, which tallies with the Belgian experience, if we remember rightly. The claim that this disease should be added to the schedule is one that, of course, must be settled entirely upon its merits. Many of the ailments to be found there now are “benign” diseases, and if men are actually debarred from earning their live- lihood through “ miner’s itch,” there is a primd facie case for its inclusion. There is the advantage that the symptoms at any rate are unmistakable and cannot be simulated; it thus has some points in its favour over a few of the other “ diseases.” Ankylostomiasis, for the present, is not an active disease in this country. As Dr. Shufelebotham observes, the “beat” series of diseases have no history of accident, and may in certain cases arise from causes outside the employment, without there being any means of settling whether they do so or not; in the case of miners’ nystagmus, the symptoms are so largely subjective that malingering is always to be suspected. The principal matter of interest, however, in this new disease is that it opens out a most attractive line of speculation. It has been found to occur up to the present in certain seams in North Staffordshire and Fifeshire ; can it be that there is any connection between it and spontaneous heating of the coal ? The distillation theory bears a striking resemblance to that which the chemists advance as being the predominant cause of gob fires, and it may be remembered that Dr. Wheeler, in giving evidence before the Spontaneous Combustion Committee, tentatively urged that some consideration should be given to the fermentation theory, which itself is founded upon the presence of micro-organisms in the coal. The parallel may be far-fetched, but it serves to illustrate the relationship between science and industry. It is now generally admitted |that the mining engineer has greatly to gain from the co-operation of the chemist; in the elucidation of the coaldust and gob-fire problems, no progress would have been made if there had been no appeal to the chemist. Similarly, the pathologist has enabled us to gain a
