The London coal market continues firm. • The colder weather has stimulated public orders. Stocks at the depots are depleted. Both seaborne and rail- borne house coals are scarce. Manufacturing coals are strongly in demand. < The general position of the provincial coal markets has changed very little since last week. In all districts the demand is considerably in excess of supply, and in the house coal markets this position has been rendered more acute by the cold weather prevailing. Exports are being further restricted. In view of the scarcity of fuel all round the tone of the markets is firm, and any spot lots available fetch maximum prices. Quite a number of important cases under the Coal Mines Act have been before the Scottish Courts during the past week. Meetings of the North of England Institute of Mining and Mechanical Engineers and the Alining Institute of Scotland took place on Saturday last. It is understood that makers of iron and steel whose works are under Government control have received intimation that they must not accept further private orders without permission of the Ministry of Munitions. Rules of procedure at colliery recruiting courts under the Military Service Act have been issued by the Home Office. Prof. Armstrong on Wednesday read a paper entitled “ The Problems of Coal with Reference to the Complete and Provident Utilisation of the Supplies. An interesting debate on the shipping question took place in the House of Commons yesterday (Thursday). Judge A. O’Connor has been appointed as arbitrator to adjudicate on the 5 per cent, wages dispute between the South Wales anthracite miners and owners.! Both the coal owners and miners in South Wales are applying for changes in the wage rate, and it has been decided to lay the matter before the new independendent chairman of the Conciliation Board, Lord Muir Alackenzie. The Coal Conciliation Board for the Federated Area of England and North Wales yesterday decided to place the men’s application for a 5 per cent, increase in wages before the independent chairman, Lord Coleridge. A short time back we drew attention The Miners’ in this column to the Seventh Report Health. of the Explosions in Mines Com- mittee, embodying Dr. Haldane^s conclusions respecting the influence of shale dust upon the health of the miner. Since the publication of that report a point has been raised in The Times Engineering Supplement to the effect that sufficient consideration had not been given to the mortality statistics of miners over 65 years of age, which, it was claimed, show a marked excess in mortality from bronchitis and pneumonia, pointing, in the view of the writer of that article, to a very serious increase in invalidity, attributable to the inhalation of stone dust, incidental to ordinary mining operations. Dr. Haldane has replied to that objection in the columns of our contemporary, and, as he wishes that reply to be regarded as a supplement to his report, it is desirable that the points raised by him in this connection should be put on record in our own columns. The matter is important in view of the present state of the stone-dusting controversy, for the criticism, if it had remained unanswered, might have had a damaging effect upon the attitude of the miners towards the proposed method of dealing with the dangers of coal dust in the mine. Dr. Haldane maintains that mortality statistics of miners above the age of 65 are not trustworthy evidence, for the following cogent reasons :—Coal miners, as a rule, seek retirement, or lighter employ- ment, on the approach of old age, to a greater extent than those following other occupations. Thus, according to the census of 1901, only 1J per cent, were older than 65, as compared with an average of 4 per cent, for other occupations. The older and less healthy of the miners would be expected to give up the arduous work of coal mining. Now, statistics show that for all males the death-rate above the age of 65 reached the total of 148’0 per 1,000 among those who retired and 88’4 among those still occupied. But, if we consider the coal miners alone, these rates are reversed, being 109’6 for the retired, and 139’8 for the occupied. We are, therefore, confronted with the apparent anomaly that it is the less healthy among the coal miners who continue their employment after reaching the age of 65 ; and the explanation, in Dr. Haldane’s view, is to be found in the higher wages and increased prosperity of the coal miners. The figures, in fact, show that a retired coal miner is much less likely to die than a working coal miner; but if he does die he is more likely to succumb to bronchitis than are those following other occupations. The reason for this, however, is not so clear. Dr. Haldane does not deny that exposure to dust may have been a contributory cause, but there are also other possible reasons, amongst which may be mentioned over-strain of the lungs, producing an emphysematous condition conducive to bronchitis. This condition may, in fact, be expected to occur in an occupation like coal mining, in which there is much heavy work and laboured breathing in an atmosphere containing too much carbon dioxide for human susceptibilities. The same heavy incidence of. bronchitis among men older than 65 is found amongst carmen and coal heavers, both of which occupations involve great muscular exertion. If, therefore, a high bronchitis death rate is the general rule in occupations associated with heavy exertions, it can scarcely be regarded as evidence of the effects of breathing stone dust. Dr. Haldane next turns his attention to the con- clusions of Dr. Collis respecting the death rate from respiratory diseases in the different coal fields. Dr. Collis showed that this death rate is remarkably low in the Durham, Northumberland, Nottingham, and Derby districts, and he suggests that this may be due to the character of the coal mines in these areas, and the low proportion of stone in the dust breathed by the miners. This conclusion, however, is invalidated by the analyses quoted by Dr. Haldane,- which show that the mine dust in the Nottingham and Derby districts contains a high proportion of stone dust—so high, indeed, as nearly to reach the proportion recommended by the Explosions in Mines Committee as a protection against coal dust explo- sions. These mines, in fact, are in a high degree naturally protected, and, in consequence, not only have they been practically immune from explosions, but also the miners themselves are typically healthy as compared with those in other coal fields. Yet, if we consider only the miners older than 65, the death- rate from respiratory disease in the Nottingham district is as high as in other coal fields. South Wales, again, has the lowest old age death-rate and the highest rate at lower ages ; while Northumber- land and Durham have nearly the highest old age death-rate and almost the lowest at the lower-age periods. Thus, Dr. Haldane concludes, the death- rates among the older colliers are not trustworthy indices of the effects of occupation. As a matter of fact, we are still far from the possession of full knowledge of the hygienic influence of dust inhalation. The human lungs appear to have a remarkable capacity for getting rid of some kinds of dust, but this process of adaptation to the environment is at present somewhat obscure. It is satisfactory to learn that this matter is still engaging Dr. Haldane’s attention, and we may look forward with confidence to the result of the further researches now being carried on for the Aledical Research Committee under the National Insurance Act. Although we are not yet in a position to define exactly the kind of dust which is to be regarded as dangerous, Dr. Haldane is sufficiently convinced that there need be no hesitation in the use of shale dust for stone-dusting purposes. We are glad that this unequivocal statement has been made, and we regard this supplementary contribution to his report as being particularly valuable in removing any impression to the contrary that might have been gathered from the somewhat guarded conclusions in the original document. It is with mixed feelings that we The find that the Board of Trade has Distribution decided to give partial expression to Of Coal. a suggestion made in these columns six months ago. With the prospect of increased stringency in the situation arising from the further depletion of labour supplies and the dedication of every effort to the production of munitions, it then appeared to us to be necessary that the Government should promote means to facilitate the passage of fuel into the channels best calculated to assist the nation in bringing the war to a successful close. It was pointed out that the Retail Coal Prices Committee had decided to regulate prices and exports, but had hesitated to round off their policy of expediency by undertaking to reorganise the system of distribution; and at the same time, as an alternative superior to that of any system of distribution by the State, it was urged that the Government should have impressed upon the coal owners the necessity of devising a scientific scheme of distribution to meet the altered conditions of trade. Steps at that time had already been taken in South Wales which promised to attain these objects locally, and it was suggested that the whole question of distribution might be greatly simplified by the formation of committees in the various coal fields, with a central organisation, to whom could be entrusted the duty not only of dealing with matters generally affecting the trade, but also of adjusting the balance of requirements as between district and district. We cannot do better than quote the words used in our issue of August 20, viz. :— The State must be, in the immediate future, by far the largest customer of the collieries, and this fact has led many worthy people to think that the time has arrived when the mines should be taken over by the State ; but we believe that the aims, in pursuance of which a Coalition Government could be induced to consider nationalisation as feasible and necessary, can be much better satisfied by enlisting the co-operation of a., concert of mine owners under any system of State control that may be deemed advisable. It has taken Mr. Runciman six months to appre- ciate the importance of this step, and it may be hoped that its value will not be discounted by any narrowness of view, which too often characterises the counsel of expediency. Eleven representative committees have been formed, or are in process of formation, and, in addition to these coal and coke supplies committees, Mr. Runciman has appointed an excellently - constituted central committee. The object, it is stated in the official memorandum, is to ensure that munition firms and other important con- sumers shall obtain the supplies they need with as little delay and friction as possible, and that the resources of the different districts are utilised to the best advantage. We trust that both ends of the question will be kept constantly in view. Much of the trouble of last year was the direct • consequence of over-rating the importance of the London household trade, and, at a time when even the most zealous upholder of economic theory must surrender his belief that supply and demand should always preserve a beautiful
