January 17, 1913 THE COLLIERY GUARDIAN. 181 gases which are liable to be encountered would prove fatal to the wearer, whereas the wastage of even a dozen bagfuls of oxygen would be inappreciable. Moreover, with the injector type of apparatus there is no warning of a leak, whereas in the “ Proto,” with its extremely handy pressure gauge, any undue loss of gas is readily detected, and a man would have time to reach a place of safety even if the wastage were much greater than the amount mentioned above. Several of the letters which have already appeared go to show that the writers do not understand the subject. Henry A. Fleuss. 187, Westminster Bridge-road, London, S.E., January 9, 1913. THE POLICY OF 41 DON’T KNOW ” Sir,—The position of the colliery manager under the Coal Mines Act of 1911, sections 15 and 16, is not at all clear. Suppose, for example, that a strike or an accident occurs, and that it becomes necessary for the manager to perform pro tern, the duties of a fireman, deputy or examiner. The question is whether, notwith- standing his possession of a first-class certificate and also, perhaps, several years’ experience as a manager, the law allows him to act as a fireman pro tern. unless he has also obtained the fireman’s certificate. Secondly. What about the “ local inspectors ” who may be appointed, under section 16, by the workmen. Must these men possess firemen’s certificates ? If not, must they be conducted by a man who possesses such a certificate ? The Act says that “ if the owner, agent or manager thinks fit ” they may be accompanied by himself or one or more officials of the mine. But the Act does not say whether any one, even of the latter, must possess a fireman’s certificate. Moreover, the local inspectors are to be thus accom- panied only “ if the owner, agent or manager thinks fit.” But suppose the manager does not think fit ? In that case, are the local inspectors, without certificates of any kind, to be allowed “ to go to every part of the mine, and to inspect the shafts, roads, levels, workings, airways, ventilating apparatus, old workings, and machinery ” ? At the request of a Cumberland colliery manager and several colliery officials, I wrote to the Home Secretary on the 2nd inst., asking him to give a ruling on these points. I now ask you, Sir, to publish his reply, a copy of which I append, and I shall be glad if you will also publish the enclosed copy of my rejoinder. H. W. Halbaum. Cardiff, January 13, 1913. [copy.] Home Office, Whitehall, 10th January, 1913. Sir,—With reference to your letter of the 2nd instant, on the subject of sections 15 and 16 of the Coal Mines Act, 1911, I am directed by the Secretary of State to say that it is open to any manager who is in doubt on either of the points which you raise in your letter, to refer to the inspector of mines, and if any manager has written to you on the subject I am to suggest that you should advise him accordingly. I am, Sir, Your obedient servant, Mr. H. W. Halbaum, Malcolm Delevingne. “ Avondale/’ 7, Mafeking-road, Cardiff. “ Avondale,” The Bight Hon. R. McKenna, 7, Mafeking-road, H.M. Principal Sec. of State, Cardiff. Home Department, January 11, 1913. Whitehall, S.W. Sir,—1 am in receipt of your letter of the 10th inst., in reply to mine of the 2nd inst., on the subject of sections 15 and 16 of the Coal Mines Act, and I note that, after a full week’s consideration, your answer is to the effect that you don’t know how these sections are to be interpreted. I must respectfully protest against the tone of your letter, and, in order to give effect to that protest, I am sending a copy of this correspondence to the Press, and also to the various colliery officials’ associations. In my letter of the 2nd inst., I asked certain questions, and you tell me that if a manager in doubt will apply to the inspector of mines he will be answered. Why may not any person interested receive a civil answer to the question ? Either you know, or you don’t know, how these sections are to be interpreted. If you do know, why not answer my questions in a straightforward manner. If you don’t know, how is the inspector to know ? Or am I to understand that the inspectors have secret instructions from the Home Office as to the interpretation to be put on the Act ? Or am I to understand that every manager who happens to be placed in a difficulty is to be entirely at the mercy of the particular inspector having charge of the particular district in which the particular manager conducts his business ? Allow me to suggest that this sort of thing is hardly worthy of a Government department. I have been engaged by the Cumberland Colliery Officials’ Association to give them two lectures on the 25th and 27th insts., at Whitehaven and Mary port, and am also invited to attend the South Wales and Monmouthshire men, and I have been asked to get such information as I can from the Home Office to enable them to put a proper interpretation upon the various provisions of the Coal Mines Act, 1911. These lectures are advertised as dealing with “Recent Mining Legislation, and how it affects Colliery Officials.” What am I to tell these men? Am I to tell them that, having carried out their instructions to the best of my ability, the Home Office has refused to give me any information whatever; or am I to tell them that the Home Secretary does not know in what way these provisions are to be interpreted ? Or, am I to tell them that the method of interpretation is a secret to be divulged only by the inspector of mines to the manager who asks for advice ? I can only warn you that, if you refuse to face these questions at the present time, you will not be allowed to shirk them at the General Election. I have been a Liberal all my life, but I have now quite made up my mind that I will spare neither labour nor expense in order to enable the miners of this country to appreciate the manner in which they have been be-fooled and exploited by the department over which you have the honour to preside. It is not only that you don’t know, or that you refuse to state, how these particular sections of your own Act are to be interpreted. The evidence of your “policy of don’t know ” in other directions is accumulating and solidifying itself into a mass that will infallibly crush the Government at the next General Election. For example, I sent you a long letter (on September 25 last) pointing out to you the iniquitous character of the surveying qualification required by the Board of Examinations from all candidates for a first-class certificate. You acknowledged the receipt of that letter, and promised that it should have due attention. I have heard nothing more about the matter from you, but I note that when Mr. Adamson, the member for East Fife, questioned you on the same subject in the House of Commons, you actually had the assurance to say that no representations had reached you which would lead you to think that this requirement would place any serious difficulty in the way of the class of candidate in question. Fortunately, I sent copies of my letter of September 25 to the mining papers, and it received wide publication, so that all the mining community know perfectly well that strong representations on the matter had reached you fully three months before you were questioned on the subject in the House of Commons. The things you ought to know, but don’t know, about the mining situation are too numerous to mention, but some of them are noted below. You evidently don’t know that coal gas is being used at the great majority of the firemen’s examination®, and that these examinations are thereby deprived of the efficiency which the framers of the Act intended them to have. You don’t know, I suppose, that the scale of gas caps corres- ponding to certain percentages of firedamp as given by the card issued from the Home Office does not agree with the scale given by the Royal Commission. You don’t know that each particular examiner for these firemen’s examinations has his own standard, which, in most cases, does not agree with the standard issued by the Royal Commission, nor with that set up by the Home Office. You don’t know, in spite of your own instruction, that it is not necessary for these candidates to attend classes, that they are nevertheless obliged to attend classes, not because they have anything to learn about firedamp, not because they lack experience in the detection of firedamp or in the removal of it, but simply because they are not familiar with the particular standard set up by the particular examiner they may have to face. Hence, they are obliged to go to these classes simply to discover what are the ill-digested views of the amateur who happens to have been pitchforked into the position of examiner. You don’t even know, I suppose, that some of these examiners have said that they accept no standard issued by the Home Office, nor by the Royal Commission, nor by any other authority whatever. So that the practical effect is that any fireman able to pass one examiner must fail under all the others. Again, you do not know that county councils do not consist of practical mining men. In some districts the control and conduct of the examinations for firemen is in the hands of men who have no practical experience whatever. Such are the institutions “ approved ” by you for examining practical men who have forgotten far more than your “ approved ” teachers ever knew about the subjects of the examination. Perhaps, also, you do not know that when the Act of 1872 was passed, acting colliery managers received “ certifi- cates of service.” Neither do you seem to know that when the Act of 1887 was passed acting under-managers received “ certificates of service.” And, therefore, it never occurred to you that in common justice the precedent established for managers and under-managers should have been followed when it became compulsory for firemen to obtain certificates Your answer to Mr. Adamson on the 1st inst. also shows that you don’t know what the mining papers are saying, or what the mining institutions are saying about the methods I of the Home Office. If you will condescend to look in the current issue of the Colliery Guardian you will find that your reply to Mr. Adamson is being severely commented on, and you will also find there what people are saying about the recent prosecution (or should I say persecution ?) of the management of the Bentley Colliery. The amount of praise lavished on Dr. Haldane for his honourable stand is only equalled by the volume of condemnation showered upon the conduct of your department. Finally, you evidently don’t know that more blocks have been put in the way of the working class candidate for a manager’s certifi- cate, and more in the way of his ambition for improved status generally by your department than have been put in the way by all the Governments of the last 50 years. The above forms a list of some of the things which you evidently don’t know. You will get a rude awakening when you face your constituents at Monmouthshire at the next election. I can only counsel you that, in so far as the mining interests of this country are concerned, and especially the interests of the working classes connected therewith, you should endeavour to place yourself in the hands of advisers who are less steeped in the worst kind of Tory classism, and more inclined to fall in with the democratic spirit of modern times than your present advisers seem to be. I am quite certain that many of the Orders which have been issued from the Home Office since the passing of the Coal Mines Act, 1911, would never have stood the slightest chance of passing the full House of Commons had they been submitted to discussion there. I will say, in conclusion, that since it appears to be impossible to extract any information from you on matters of public interest to all classes of miners, I shall, in future, direct my enquiries to members representing the mining interest. Perhaps the replies you will give these gentlemen from your place in the House of Commons may be less evasive and more straightforward than those which you have condescended to/give to myself. As a start towards this end I am this day sending to Mr. Adamson, the member for East Fife, a full account of how the class he represents has been fooled and duped by your department ever since you took charge of it, and I shall not fail to enlighten colliery officials and managers generally as to the further treatment they may expect at your hands unless they decide to deal with you and the other members of this “ most democratic Government of modern times ” through the ballot box. I am, Sir, Your obedient servant, [1 enclo.] H. W. Halbaum. CONTROLLING GEAR ON WINDING ENGINES. Sir,—I, also, have wondered what safety there is in the controlling gear for the persons who are riding on the cage which is descending, for all the controlling gears act only when the cage has travelled its distance, and there is nothing to control the descending cage. I may say that I have designed a contrivance which will prevent the cages da ihing into the sump planks, which can be under the control of the enginewinder or can be actuated by the onsetter. Controller. Church-street, Chasetown, January 13,1911. TO CORRESPONDENTS. Durham Gas Coal. Constant Reader (Parley).—The term ‘‘special Wear gas coals ” applies mainly to the coals wrought at the Wear mouth and Londonderry collieries. In addition to the foregoing the coals obtained from Wheatley Hill and Wingate Grange collieries are commonly described as “ gas specials.” At a meeting of the Manchester section of the Society of Chemical Industry, held last week, Mr. J. E. Christopher read a paper on “ Progress in By-product Recovery at Coke Ovens.” Dealing with the question of the outlets for the various by-products, Mr. Christopher said in this country the use of sulphate of ammonia had not made headway as compared with its use on the Continent. There was plenty of scope for the work of the Sulphate of Ammonia Committee, when they considered that out of our production of 369,000 tons, only 70,000 were used in this country, while practically the whole of the German production was used on German soil. The outlets for tar also appear promising. The main outlet for benzol must lie in the direction of motor spirit. In 1905 the import of petroleum spirit into the United Kingdom was 19,459,000, in 1906 26,335,000, and in 1907 33,180,000. Assuming an average yield of one gallon of motor benzol per ton of coal, the coke works of this country could turn out 19 million gallons annually, so that the field for the exploitation of benzol as motor spirit was extensive. The production of gas for purposes of illumination as a by-product of the coke industry, had lately made considerable headway. In the six years from 1903 to 1910 the amount of gas produced in this way in Germany had increased from 13| million cubic feet to 1,472 million feet, and a company had been formed to supply coke-oven gas to the municipality of Ghent, in Belgium, at a price equivalent to 5'4d. per 1,000 cubic feet. In the discussion which followed the paper, Mr. W. H. Coleman said that if the whole of the coke made in the country was made with recovery ovens, he thought they might get about 29 million gallons of benzol.
