February 5, 1915. THE COLLIERY GUARDIAN. 293 serious had happened than a heavy fall of roof, killing one man and injuring, three others, But the fall here and else- where in the pit had been such that the No. 2 pit of the Cadeby Colliery was rendered unworkable for the time being, whilst there were circumstances associated with the occur- rence of an unusual character. It was at first believed that a severe earthquake shock had been experienced in the district. There 'are many who still hold to this theory. Others contend that subsidence in the coal, workings was responsible for what occurred; whilst a third, and an utterly unsupported and untrue assertion, was that there had been another explosion at Cadeby. It appears that about 9.45 on Monday night a Conisboro’ miner named Emanuel Jordan was returning to the pit bottom, having finished his after- noon shift in No. 2 pit. When a short distance from the shaft there was the sound of a disturbance, and a quantity of roof fell, burying Jordan and some other men. The others were got out, but Jordan lost his life. Mr. W. H. Chambers, the managing director of the Denaby and Cadeby Colliery Company, expressed the opinion that the shocks were local earthquake shocks. Another explanation was that what happened was due to ground weight. Experts describe the occurrence as an extensive bump. Certainly its effect was felt over a wide area of Conisboro’, and was alarming enough while it lasted, many people being under the impression a German air raid was in progress. Part of the pit workings underlie the estate of Mr. F. J. 0. Montagu, of Melton Park, a former High Sheriff of the West Piding. At the time of the occurrence the Hon. Mrs. Lindley Wood, mother of Mr. Montagu, was sitting before the fire in the drawing room. The old mansion of solid stone masonry fairly rocked, the lady was twisted round in her chair, and her daughter, who was in her bedroom, was thrown to the ground. There were many other similar experiences, pointing to earthquake shock or violent seismic disturbance. The inquest on the deceased miner Jordan was opened by Mr. F. Allen at the Eagle and Child Hotel, Conisboro’, on Tuesday night. The coroner said the man met his death by a somewhat extensive fall of roof. There had been many alarmist and grossly exaggerated reports of the accident at the pit, and the whole district had been flooded with tales of explosion, and of so many killed. It was the duty of the jury to discount all this. There had been what was known as a bump, followed by a considerable fall of roof. Whether this was in the ordinary course of coal mining, or was brought about or contributed to by earth movements, they were not at present able to express an opinion. It might be that in addition to the normal subsidence following all colliery workings there had been a slight earthquake. But it was very undesirable to have, as had happened that day, small boys .tearing round the streets of Doncaster and Mexboro’ talking about another explosion at Cadeby, and putting the whole towns in, a panic when there was no foundation for it. What had happened was what happened every day in England. Those who had been slightly injured would be able to attend at the adjourned inquest. There was no reason to anticipate any further lives would be sacrificed. The enquiry was then adjourned to Wednesday, February 10, at 10.30 a.m. Lancashire and Cheshire. Canadian Props for the Bridgwater Collieries — Hulton Pollution Case. At a meeting of the members of the Altham and Great Harwood branches of the: Lancashire and Cheshire Miners’ Federation, held at Accrington on Saturday, Mr. Elce was presented with a silver salver as a token of esteem from the miners, on the occasion of his retirement, and Mrs. Elce was presented by the miners with a silver tea and coffee service. The gifts were handed over by Mr. Thos. Ashton, secretary of the Miners’ Federation of Great Britain, and Mr. J. McGurk, miners’ agent of the Lancashire and Cheshire Federation. Owing to the serious depletions in the ranks of their workers through recruiting, certain coal owners in the Man- chester district last week posted up notices intimating that it would be advisable on the part of other employees to interview the management before enlisting. The Earl of Ellesmere, who owns several of the largest collieries in South-East Lancashire, has purchased some hundreds of tons of Canadian props averaging 12 or 14 ft. in length, and these are stacked in a field adjoining his Tynesbank depot, Walkden. The props will be sawn to the requisite lengths for “ spragging ” purposes. Mr. John Allen Parkinson, of Bamfurlong, who has been elected to fill a casual vacancy on the Lancashire County Council caused by the death of Mr. E. A. Johnson, colliery proprietor, of Bickershaw Hall, is the first member of the Lancashire Miners’ Federation to be appointed to a seat on the county governing authority. The trial of the motion in which the Vice-Chancellor of the Palatine Chancery Court is asked to grant an injunction restraining the Hulton Colliery Company Limited from allowing polluted water to enter the Carr Brook,' has been continued at Manchester during the past week. Mr. Percy Bean, analytical and consulting chemist, was called on behalf of the plaintiffs, and stated that he had analysed samples of the water taken by himself and others. That which came from the Pretoria pits was of such a nature that he did not think any system of treatment would make it fit for boiler purposes. Mr. Bean added that he did not think the defendants could have adopted a better method of treatment than the Archbutt-Deeley process, but even if it were carried out carefully and skilfully, the effluent would be unsatisfactory. However, in his opinion, it was impos- sible to ensure correct treatment; the water would be either over-treated or under-treated, and the effluent, therefore, even more objectionable. Analyses of samples taken recently revealed the presence of excessive quantities of sul- phate of sodium and chloride of sodium, there being in one case as much sulphate as 842 parts in 100,000. Other soluble substances were also found. During the process of evapora- tion these would concentrate in the boiler, and when the saturation point had been reached serious consequences would follow. The water would be thrown into the steam pipes, and possibly get to the engine cylinders. He attri- buted the corrosion to the water, but he could not say what the particular ingredient was; probably some change took place in the boiler. Mr. J. B. C. Kershaw, of Liverpool, attributed the corrosion of the boilers to the sulphates, chlorides, and alkali in combination. Therefore, under modern boiler conditions, a steel plate might be attacked which would escape if the temperature was lower. He should not recommend anybody to use a boiler feed water containing more than 20 parts per 100,000 of total solids. Mr. Atkinson, K.C. (for the defendants) suggested that the eminent Swedish chemist, Berzelius, discovered that caustic alkali rather preserved iron from rust than assisted corrosion. The Witness would not agree, and added that he was con- vinced that in another 20 years land boilers would be worked on the same basis as marine boilers, that is, with condensed' waters. Every works would have surface condensers, and put nothing but pure water into the boilers. That would get rid of corrosion troubles. Mr. Wm. Henry Booth, con- sulting engineer, of London, said the water from the Pretoria pits was shocking; he had never seen the like before. Even after treatment the effluent was totally unfit for boiler purposes., It was extremely doubtful whether salts in pro- portions which had hitherto been regarded as harmless in a boiler would be really so under modern conditions. For example, sodium sulphate was extremely soluble up to 104degs. Fahr., but beyond that limit its solubility decreased. He fixed the limit of total solids at 25 grains per gallon. The treated water contained common salt (sodium chloride) and sodium sulphate. Taken separately, or even in conjunction, they were harmless as regards corro- sion, but if either were present with carbonate of soda the water became objectionable. He had heard that corrosion of boilers was sometimes set up by stray currents of elec- tricity, but he had not been able to trace any case of that kind. Mr. William Briscoe Baron, analytical and consult- ing chemist to the Vulcan Boiler and General Insurance Company Limited, Manchester, said he was familiar with the Archbutt-Deeley process, and he thought its adoption was the best course the mine owners could follow. The effluent produced in this case was not a desirable one for use in boilers. The Plodder water was extremely bad, particularly for boiler purposes, because 47-9 of total hard- ness was present with a large amount of dissolved solids. Seeing that the permanent hardness was as high as 38-4, and the temporary hardness so relatively low as 9-5, while the magnesium salts amounted to 20 grains per 100,000, he should say the water was highly corrosive. The calcium salts, 44-4, would tend to make scale. He admitted that if the colliery company, on finding the effluent was too high as regarded hardness, subjected it to re-treatment, the objec- tion of over-hardness would disappear. Mr. Wm. Ingham, consulting engineer in practice in Manchester, speaking with 40 years’ experience in the .working and inspection of boilers, agreed that the effluent from the Pretoria pits was unsuitable, mainly on account of the presence of a large proportion of dissolved solids. He had never, before come across a water like the untreated Pretoria water. It was particularly corrosive. The Arley and School pits waters were also objectionable. Cross-examined, witness said that given, a water without any lime he would not object to 100 grains per gallon of, sodium sulphate. Speaking generally, sulphate of soda in itself in a moderate degree was less harmful than the same number of grains of lime per gallon. Mr. Cunliffe having summed up the case for the plaintiffs, Mr. Atkinson addressed the Court for over three hours on behalf of the colliery company. The Pretoria Pit, he said, was one of the finest coal mines in the country, equipped with all the most modern machinery, and found employment for nearly 3,000 men, involving a wages bill of some thousands of pounds per week. Great attention had been paid to the treatment of the water turned out from the pits, and the. defendants had practically reached the limit of human knowledge—all that science could suggest had been carried out. There was no other way of purifying the water than the one they had adopted, and the effect of an injunc- tion might be to close the mine. Counsel called attention to the fact that the witnesses for the plaintiffs admitted that before taking the samples for the purpose of analysis they disturbed the water in the dam, which in itself was an unnatural accumulation. He contended that samples should have been taken before the water was agitated, and any ochre which might have been deposited on the bed of the stream had been disturbed. The plaintiffs had shirked the issue the Court had to try, and there was not a tittle of evidence to show that, with the natural flow of the stream, any material quantity of ochre would have been taken into the various mills. Nor had any witnesses been called to prove that the hardness of the effluent was, as a whole, worse than the natural brook water. The relief asked for by the injunction was limited to water pumped from the collieries into the stream, and there was no complaint of water percolating from the shale heaps. An injunction must be interpreted with reference to the sources of pollution pleaded in the statement of claim, and it seemed to him that the introduction of the surface water was not relevant to the issue, and might have been put on one side. With regard to the School Pit water, his clients claimed a prescriptive right, and if they could show that the amount of pollution coming from that source was no greater now than it was 20 years before the action was brought, it was no answer to say that the effect produced had varied. Evidence was then called on behalf of the colliery company. . Mr. Christopher Thompson, who for many years had acted as mineral sur- veyor for Sir Wm. Hulton, the owner and lessor of the mines, produced working plans of the colliery. He made surveys from 1891 to 1908, and during that time he saw no change in the quality of the water coming from the School and Deep Arley pits. Mr. Joshua Bateson, mechanical engineer at the Hulton Collieries, said he had been employed there continuously since 1893. In his opinion the quality of the School and Arley water was practically the same now as in 1893, and the quantity was rather less. An old pump which started working in 1867 was capable of dealing with 600 galls, a minute. It was obvious the mining engineer who asked for the pump, and those who designed it, were in contact with a large amount of water, and they put in a pump which was capable of pumping in 12 hours consider- ably more than the present quantity of water at the School and Arley pits. In 1900 a duplex pump was put down, each capable of pumping 22,000 galls, an hour, but they were worked in turn and not together. The maximum quantity pumped from the School Pit was about 240,000 galls, in 24 hours, and in dry weather about 200,000 galls. For the Deep Arley the average was 62,640 galls, per day, and the average quantity of treated water from the Pretoria pits was 38,057 galls, per day. The witness was under exami- nation when the case was further adjourned till Wednesday. North Wales. Llay Main Colliery—Van Lead Mines Closed. Mr. Thomas Davies has succeeded Mr. E. T. Davies in the management of the Wynnstay Collieries, where he has been employed in various posts throughout his career. Mr. T. Davies is highly popular among the men at this colliery, and highly 'successful as a teacher of mining under. the Denbigh County Council, under whose Education Committee he has successfully conducted classes for a number of years. Lieut.-Col. J. S. Hughes, of Nevin, Carnarvon, who was fot many years manager of the Festiniog Railway Company, and consulting engineer to several North Wales collieries, has left estate valued at £8,194. With reference to the new colliery which is being sunk by the Llay Main Collieries Limited near Wrexham, the Hawarden District Council have made a claim on the com- pany on account of alleged extraordinary traffic over the Council’s roads. In suggesting a meeting between both sides on the matter, the colliery company have pointed out that the Council stood to gain very considerably in the long run by the establishment of a large colliery concern in the neighbourhood, and that this should be taken into consider- ation in dealing with the matter of the claim. The clerk to the Council has replied to the effect that no more than a fair settlement was desired, and it has been decided that the chairman of the Council, together with the clerk and the surveyor, shall meet the representatives of the colliery com- pany, with a view to an amicable settlement of the matter in dispute. The Van Lead Mines, near Aberystwyth, have again been closed, whether temporarily or permanently has not yet been decided, but a majority of the men have hastened to join the Colours. This mine has suffered vicissitudes of fortune, and is one of the oldest known mines in North Wales. It is stated that mining took place in the locality of these mines even before the coming of the Romans, and were worked regularly during the Roman occupation of these islands. Subsequently the industry was neglected until the 17th century, and it was not until the middle of the 19th that any appreciable efforts were made to win the minerals located there. Notts and Derbyshire. At a meeting of the Nottingham City Council on Monday, February 1, the Mayor (Aid. J. H, Gregg) and Mr. A. R. Atkey, the chairman of the responsible committee, moved and seconded respectively the confirmation of the resolution approving the promotion in Parliament of the Bill to transfer to the Corporation the powers of the Trent Navigation Com- pany, as they apply to the river between Newark and Nottingham. The Council passed the resolution by 37 votes to 5. The Midlands. Coal Famine in Warwickshire. A coal famine is reported from the Midlands this week as the result of the extraordinary shortage in the supplies of fuel from the pits which has recently been so marked a feature. Colliery owners and merchants have given pre- ference to the demands of the manufacturers and ironmasters, with the result that many householders are now almost without coal. But even among the manufacturers supplies coming to hand by rail and canal are by no means equal to necessity, and the consumers of steam coal report the famine to be quite as acute with themselves as it is with respect to domestic sorts. Certain of the leading local coal merchants’ associations have this week supplied the information that the chief difficulty is that the Warwickshire pits cannot raise fuel in sufficient quantities to meet current needs on account of the shortage of men, because of; their having enlisted, and that, further, when the fuel is brought to bank, there are not sufficient men on the top to fill the trucks. Prices in Warwickshire, and also in Staffordshire, are now higher almost than they have ever been known to be, except in times of strikes, and at many of the collieries prices are practically up to a strike period. Coal merchants this week declare that at some of the pits current rates are 3s. to 4s. per ton higher than the customary winter prices, and an early repetition of the colliery price lists of rather better than a month ago, showing advances varying from Is. to Is. 6d. per ton, is considered entirely likely. On Cannock Chase the ruling prices for domestic coal are about 24s. 6d. for best, down to 21s. fid. for smaller coal of reliable domestic quality. Contractors everywhere are considerably harassed to complete their orders. Boats are leaving the pits loaded to not more than half their weight, and it is even said that in some cases 30-ton boats have to leave the colliery wharves with not more than seven or eight tons of coal. Supplies sent from Cannock Chase to London and the south are held up for days in transit through the lines being blocked with military traffic, and although the colliery companies are doing their best, it is evident that in the present extra- ordinary circumstances the carrying out of contracts is absolutely impossible — a point which buyers should care- fully note. The Gas Department of the Birmingham Cor- poration have made known this week that ever since the coal strike in August 1911, the policy of the department has been to keep a very large stock, and that the stock now in hand is of good proportions. Even 'should no further supplies be received, it is sufficient to tide the department over for several months, but exactly how long it is impos- sible to say. The coal used comes mainly from the Derby- shire and North Staffordshire pits, while some is supplied from Yorkshire. The greatest distance over which it has to be transported is about 70 miles. In this respect Birmingham is not so much handicapped as are the London gas undertakings. Kent. In connection with the effort to raise from the shareholders .£100,000 for the Snow’down Colliery deep sinking and other works in the Kent coalfield, a representative meeting of shareholders in seven companies of the Concessions Group, viz., Kent Coal Concessions, South-East Coalfield Extension, Extended Extension, Deal and Walmer Coalfield, East Kent Contract and Financial Company, Intermediate Equipments, and Guilford Colliery Syndicate, was held under the pre- sidency of Mr. John Dewrance, chairman of the share- holders’ committee. Mr. Dewrance outlined the scheme of the committee for saving the properties, and a resolution was unanimously carried approving of the programme set forth by the directors, which includes the opening out of the deep seams of the coalfield by continuing the sinking of one shaft of Snowdown Colliery right through the coal seams proved by the borings. Another resolution, recommending shareholders to subscribe for the bond issue, was also carried unanimously. It is understood that promises repre- senting something like half the money were made in the room by various large shareholders. Amongst the seams below the Snowdown Hard, Mr. Dewrance mentioned are seams of 6 ft. 9 in., 4 ft. 7 in., 4ft., and 9 ft. 6 in., the borehole samples of which have all given good analyses. Scotland. Compensation Costs—Railway Rates. Mr. Wm. Liddell, oversman at Greenfield Colliery, Hamilton, has received a well-filled purse of sovereigns on the occasion of his leaving to fill an appointment in Wellington, New Zealand. The joint meeting with representatives of the Scottish coal owners and those of the miners on the question of
