584 THE COLLIERY GUARDIAN September 17, 1915. Dr. Haldane, in reply, thanked the institution most heartily for the great honour it had done him. He did not recognise himself in Sir Thomas’s portrait. He had done his best, and Sir Thomas had very much exaggerated any claims he possessed to their gratitude. He felt that there were other members of the institu- tion to whom the medal might have been more fittingly presented on this occasion. He took it, however, that in selecting him for the honour, the institution wished to signify that it was grateful to those connected with pure science for such efforts as they were able to make to help, so far as was possible, the mining profession in solving the almost everlasting questions which the mining engineer was constantly confronted with in his work. His own experience of mining had shown him how difficult and puzzling these questions were. They, men of science, only contributed a little here and there towards the solution of these problems, but it was a great pleasure to them to contribute what they could, and nothing gave them greater pleasure than to see practical application of their purely scientific work. A great deal of scientific work lay on the shelves of libraries before it was practically applied. But when by any chance the application of this work could be seen by the man who had done it, it was in every case an enormous pleasure. One had seen scientific men almost as pleased as children over some comparatively simple application of some of their pure scientific ideas. It was also a great pleasure to them to find themselves brought into personal contact with the men who were doing the country’s work and the work of humanity in other spheres than the somewhat narrow one to which they, scientific men, were confirmed. Their connection with practical affairs not only gave them many interesting problems to solve, but also reacted very markedly in stimulating them to purely scientific work : it presented problems and suggested solutions which they had never thought of before. He might illustrate this from his own experience in connection with mining work. One of the first questions which brought him into connection with mining work had reference to the composition and the effects on men of blackdamp. In this work he was fortunate enough to have the co-operation of Dr. "W. N. Atkinson, now chief inspector of mines for South Wales, a former president of that institution, and one of the ablest men he had ever met. What interested him perhaps was the effect of blackdamp on breathing. He remembered the cautious way in which they tried the effects of black- damp. Dr. Atkinson brought him to an old dip in an ironstone mine, a very steep incline of about 1 in 2 or 1 in 3. This was full of blackdamp up to the top, and the quantity of course increased as they went down. They wanted to get the effects on breathing and on lamps at the same time. They had to be very cautious about the way they went down the dip, because if they had tumbled over they would have rolled into air where there was no oxygen at all. This was before the days of birds and mice. They started at the top with an ordinary oil flame and a hydrogen flame, and he (Dr. Haldane) had an electric lamp with which to watch the colour of Dr. Atkinson’s face. He knew that as long as his face was not blue they would not tumble over suddenly. Quite at the top of the dip the ordinary oil flame went out owing to the state of the air. As the oxygen went down the hydrogen flame got longer and longer, and they began to pant more and more, so that it was rather a comfort to him when at last that flame also went out, and they thought they had gone far enough. At that time they were both panting tremendously hard, and they were glad enough to get back. He had previously known that the panting was due to carbon dioxide in the air, this being one of the constituents of blackdamp, but an interesting thing was that the pant- ing increased out of all proportion to the increase in the percentage of carbon dioxide. With 3 per cent, there was very little panting, so little that it was hardly noticeable, but when the percentage got to a little more than 5, the panting was extreme. This great increase suggested the means by which ordinary breathing was regulated, and it led to the discovery of the fact that ordinary breathing was so regulated as to keep the per- centage of carbon dioxide in the air of the lungs at about 5’7 per cent. They could easily get a sample of the air in the lungs and analyse it. If the percentage went the least bit above that they got great panting, and if it went below, natural breathing stopped for the time until the percentage collected again. This regu- lation, which was quite unknown at the time, was of such a nature as to keep exactly 5’7 per cent, carbon 'dioxide in the air of the lungs. This law was far worse than the Home Office regulations, because it worked both ways : they must keep it exactly 5’7 per cent.— neither more nor less. If they washed too much carbon dioxide out of the body they might kill themselves from asphyxia. This was a very interesting physiological regulation which was suggested by going into the bad air and watching the effects, and it was a very funda- mental one. The discovery had probably given rise to more physiological literature during the last four or five years than many others. His point was that it was the actual practical work of going in among blackdamp that led to the purely scientific discovery. Apart from scientific work, he had learned to understand and esteem the work of those engaged in the great mining profes- sion. The friendships he had formed with members of that profession were among the things which he most valued in life. He should value that medal not only as a high personal honour, but as the gift from friends to one who deeply valued their friendship. (Applause.) The President said he could assure Dr. Haldane that there was not a single word in his speech which had not been very carefully checked by the censor. It was submitted to a party of physiological and chemical friends, who came to the conclusion that he had left out a great deal that they would like to put in, but he had to tell them that they could only barely indicate a very small fraction of the enormous work which Dr. Haldane had done, not only on behalf of the mining community, but on behalf of science generally, the results of which would accrue for many years to come. The Charter. The President went on to propose ‘ ‘ That this meet- ing approves of the first by-laws to be made under the charter of the institution, which have been adopted by the council.” He said that for many years there had been an attempt to raise the question of obtaining a royal charter, but it only reached its final and successful phase through the accelerating influence of their last president, Sir William Garforth, during the second of his three terms of office. Sir William had received the loyal help of the different institutes scattered throughout the country. He did not think Sir William would like him to discriminate between the seven, but, at the same time, he was sure that the other six would be quite willing to support him in mentioning specially the public-spirited attitude of the North of England Insti- tute of Mining and Mechanical Engineers. (Applause.) They readily accepted the system, and agreed to a capital fund, which resulted in their having to pay a bigger fraction than any others. They were already in possession of a royal charter, and yet they were glad that the rest of the institutes might come in and share the privilege, so that one could say honestly that they had shown a clean, healthy public spirit. That had given ’him an additional feeling of the healthiness of the mining community in this country, the feeling that one gathered in dealing with mining men in India. One should mention on that occasion the attitude of the institutions of mining and metallurgy. Previously the two bodies had been in competition, and had frequently trespassed on one another’s domains, but now they had agreed to define and limit their spheres of influence, and, instead of competing with one another, they were now in co-operation, determined to maintain the high stan- dard of technical competence, and keep up the profes- sional etiquette which would mark out the British engineer in every part of the world. For the advantage which the institutions had thus gained they were indebted to the happy possession at a critical time of two public-spirited presidents, who were able to subordinate their parochial interests to the greater interests of the mining community and the profession generally which they adorned. There were few changes of the by-laws which were not obviously necessary, and the natural outcome of a new organisation : all of them had been accepted by the seven institutes, by whom they had been considered on various occasions independently. They had also received the approval of their distinguished legal adviser, Sir Frank Crisp, and, in principle, they had been accepted by the Privy Council. The principal changes of importance occurred in the objects of the institution, stated in the first paragraph, which now read : “ For the advancement of the coal and iron mining and allied industries, more particularly in relation to stratified deposits.” That supplemented the statement made by the Institution of Mining and Metallurgy, which was now confined to the mining of minerals other than coal and the metallurgy of metals other than iron. To fall in line with, the standard adopted by other principal metropolitan institutions, it was proposed to raise the age for full membership to 30, providing, of course, a grade of associate membership for those who were below that age. Formerly the federated institutes had power to elect members themselves to be not only members of their own institutes, but of the federated institutions. Under the new constitution this was reserved for the council, which would be composed of representatives in strict proportion from the different institutes. All these principles had been explained to the Privy Council, and were so arranged that they fell in line with and supple- mented the constitution drawn up by the Institution of Mining and Metallurgy. The two institutions had received their charter on exactly the same day, so that they were not, as stated in the annual report, merely sisters, but twin sisters. He therefore had much pleasure in bringing the resolution forward, and he asked the permission of the meeting to sign the bv-laws and rules. Mr. Lupton proposed as an amendment that the con- sideration of the by-laws be adjourned to another meet- ing. He did not think that that body should be asked to approve by-laws which it had not seen. He gathered from the chairman’s remarks that some important matters were contained in the by-laws. One was that a man must be 30 years of age before he could become a member of the institution. Well, he was a member long before he was 30, and he considered it a great hardship to be prevented from joining simply because of age : one man at 21 might be far more capable than another at 45. He thought they might adjourn the consideration until the by-laws had been circulated and printed. There was too great a tendency nowadays to tie up their institutes with rules and by-laws. The President pointed out to Mr. Lupton that the by-laws and rules had been circulated through the different institutes, and had been returned by them as approved. What steps were taken among the insti- tutes to circulate them was a matter which that meet- ing could not enquire into, nor could they enquire whether Mr. Lupton or anybody else had attended the meetings of the local institutes for that purpose. Under the charter, unless the by-laws were passed within six months of the date of the charter, the charter would fall through, and that was the only general meeting which was available for the purpose. The amendment was not seconded, and the resolu- tion was carried, only Mr. Lupton dissenting. The meeting then passed on to the discussion of papers. A full report will appear in next week’s Colliery Guardian. TRADE AND THE WAR. Enquiries in official circles are said to have shown that the restrictions with regard to the consumption of liquor imposed as a result of the work of the Central Control Board (Liquor Traffic) have had a marked effect in all the districts which have been dealt with by that authority. The evil, however, has by no means disappeared. The high values now placed on shipping property have been shown very plainly at the public sales of steamers held in London last week. The prize steamer ” Emil,” of 2,991 tons, built at Newcastle in 1904, was sold for 1-58,300, which represents more than £19 per gross ton. Just two years ago she was sold by a British firm to her late German owners for £28,000. The Danish steamer, “ Lucy Anderson,” of 1,052 tons, built at Newcastle in 1904, was soil to a British buyer for £26,400, or as much as £25 per gross ton. A Special Munitions Tribunal sat at Sheffield on Saturday to enquire into a complaint against Charles Horton and Sons Limited, brass founders, Sheffield, that they had given employment to a man named Furness who had not obtained a leaving certificate from his previous employers. The com- plaint was made by Benton Brothers Limited, brass founders, Rodley Lane Foundry. Defendants were fined £5, and ordered to pay £2 2s. towards the cost of the case. The St. Pancras Borough Council has acted upon the suggestion of the Board of Trade that the stocks of coal at the electricity works should be increased in order to reduce the demand upon the pits and the transport companies to a minimum during the winter. The Council has purchased 1,000 tons of Nuneaton double-screened nuts at 22s. 6d. a ton, delivered from Messrs. Facer and Company, and 1,000 tons of Newdigate nuts at 22s. 7d. per ton delivered from Messrs. J. H. Beattie and Company. Purchases in replenishment of stock have been made as follows :—1,000 tons Newdigate beans at 21s. a ton; 500 tons fin. Hucknall at 19s.; 2,000 tons double-screened Newdigate beans at 21s.; and 1,000 tons double-screened nuts at 22s. 6d. Reference to the lack of coal in Turkey has been made in a letter of an Austrian residing in Constantinople to a friend in Salonica. He states that the war industry is chiefly hindered by the shortage of coal, which is beginning to manifest itself in a most alarming manner. For a long time, he says, private factories have not made use of coal, but have had to fall back on wood and other substitutes, which greatly diminish the output. Coal has been requi- • sitioned from all sources. The steam tramways and the funicular, as well as the other local trains, have had to be stopped. The advisory committee of the Newcastle Chamber of Commerce has received the following official intimation in response to earlier representations :—In view of the peculiarly “ prompt ” nature of the coal trade between British and French ports, it has been decided that names of steamers need not appear in applications for licences to export coal to France and French possessions, or be subsequently sent to the War Trade Department, and will not be inserted in licences for shipment of coal to ports in France and French possessions. It must, however, be understood that all licences, except general licences, are valid for one shipment only. The above-mentioned relaxation of the requirements of the Coal Exports Control Committee in no way restricts the power of the Customs for any reason to refuse clearance to a particular vessel; and shippers should in all cases submit to the local Customs the names of vessels by which they propose to make a shipment as soon as they are known to them. A spirited and outspoken address was delivered by the Minister of Munitions last week to the members of the Trade Union Congress at Bristol, in which he appealed to the workers not to put any obstruction—such as restrictive rules and regulations—in the path towards victory. He said the members represented one of the most powerful forces in the life of the country, and without their help the cause was lost. They only had to read the story of the last 12 months to realise how much organised labour meant. The recent onslaught on the Russian army had only been made possible by the organised labour of Germany working without stint or strife and without restriction for many months. At the present moment 80,000 more skilled men and 200,000 unskilled men and women were required. If every skilled workman in the kingdom was employed, there would still be a deficiency of labour for the task in hand, so that unskilled labour must not be barred by the unions. Another direction in which the trade unions could help was by suspending during the war all practices and customs which had the effect of preventing men turning out as much work as their skill and strength would permit. If this was done they could increase the output in some cases by 30 per cent., and in other places by 200 per cent. Another point was to have no stoppages in essential work during the period of the war. The Government were carrying out their part of the recent bargain made with the unions, but, on the other hand, the latter in far too many cases were not carrying out theirs. He gave illustrations of cases in which work had been restricted by trade union obstruction. A new Proclamation relating to trading with the enemy points out that doubts have arisen regarding the position under the Proclamation in force It states that the expression “ enemy,” notwithstanding anything in the previous Proclamations, is declared to include and to have included any incorporated company or body of persons (wherever incorporated) carrying on business in an enemy country or in any territory of the time being in hostile occu- pation. In his monthly message to the members of the Boiler- makers’ Society, written this time from ” Somewhere in France,” Mr. John Hill, the general secretary of the society, refers to his visit to the trenches, and says officers and men asked him how it was that required munitions had not arrived. He was asked, “ What about the engineers’ and miners’ strikes?” and to this question Mr. Hill admits he could give no answer satisfactory to them. It was no use telling them how much employers were blameworthy : their conviction was that no personal gain or loss justified the slightest delay in producing munitions, and that workman or employer responsible for such delav should be shot as a traitor to his comrades and brothers in the trenches. Immingham Coal Exports. — The coal exported from Immingham during the week ended September 10 consisted of 685 tons to Dunkirk. The total for the corresponding period of last year was 31,038 tons foreign.
