SIMCOCK’S LETTER OF JUNE 23. Sir,—I assume Mr. Simcock means the Explosions in ' Mines Committee in his reference to the Experimental Committee, and in my reply I rely on data obtained from No. 5 report. Mr. Simcock apparently confuses two sorts of dust referred to in this report, viz. : Altofts shale dust and fullers’ earth. The report provides an analysis of Altofts dust showing 51*92 per cent, silica, and on p. 34, “ rational analysis quartz 35*2 per cent., and it is from this Mr. Simcock apparently gets his free silica figure. But he makes a great mistake in saying this is the dust recommended. Up to a certain point the experiments were conducted with Altofts shale dust. But the successful experiments were carried out with finely ground fullers’ earth, but no analysis of this dust is given in the report, beyond mentioning “ it contains 58 per cent, silica, combined and free ”—the free silica in this earth is negligible as it is nearly all in combination, as Mr. Simcock can readily ascertain for himself. The successful experiments were carried out with this fullers’ earth, which on account of its buoyancy (S.G. 1*6) was capable of being raised in suspension on equal terms with the coal dust—over and over again the report lays great stress on the desirability of fine dust being used because of this buoyancy, and we are justified in assuming that fullers’ earth is meant in all these recom- mendations. On p. 29 “ but a mixture of 50 per cent, of incombusti- ble matter may be raised in a cloud ” (evidently means fullers’ earth, as experiment 225 brings this feature 4 emphatically to our notice), “ it might be in our opinion most usefully adopted now.” This recommendation plainly refers to this fullers’ earth; such being so the next consideration is the effect of fine dust on the respiratory organs—this fullers’ earth would not be injurious, neither would suitable colliery shale prepared in the same way, z.e., ground to a suffi- cient buoyancy to float on the ventilation current. It is accepted by all that the dust should be suspended on equal terms with the floating coal dust. From figures provided by a dusty South Wales colliery it is found the fine coal dust deposits about 7 cwt. per mile of roadway per 24 hours, so 7 cwt. of this fine fullers’ earth distri- buted per day per mile would comply with the recom- mendation of No. 5 report in this instance, and it is proving so apparently by practice, judging by the amount actually used. Can anyone pretend that a steady application of 7 cwt. fine dust during 24 hours over a mile of roadway is going to make any difference at all noticeable by people engaged therein ? I shall be pleased to provide your readers with any further details in my power, and trust this explanation will enable Mr. Simcock to consider the stone dust question more favourable. L. G. Hill. 5, Oxford Road, Acocks Green, July 7,1914. Grimsby Coal Exports.—The export of coal from Grimsby during the week ended Friday, 3rd inst., totalled 18,333 tons to foreign destinations, and 453 tons to coastal ports. Shipments were as follow :—Foreign : To Bergen, 1,475 tons; Christiania, 1,437; Dieppe, 972; Esbjerg, 615; Gothenburg, 3,139’; Hamburg, 1,456; Harnas, 2,199; Hudiksvall, 426; Malmo, 1,807; Rostock, 1,137; Rotterdam, 162; Skein, 716; Trondhjem, 1,479; and Ystad, 1,322. Coastal : To Lerwick, 350 tons; London, 103 tons. Mining Subsidence.—At the Newcastle Assizes on Wednesday, Mr. Justice Bray gave judgment in the action in which James Bainbridge, of Westerhope, sued the South Derwent Coal Company Limited for damage to property, alleged to have been caused by subsidences following mine working. Mr. Scott Fox, for the plaintiff, stated that correspondence had passed as to cracks as far back as 1907, and he showed from the colliery books of workings that these complaints coincided singularly with workings in the neighbourhood. In June last year it was stated the company repudiated all liability, stating they had not worked in the vicinity for six years. The plaintiff gave evidence as to complaints from time to time from tenants as to the property settling and walls cracking, etc. His lordship, without giving his reasons, assessed the damages at £137 10s., which, he said, would carry up to the present day. Liability having been admitted by the defendants, it was only his duty to fix the damages which had been sustained within the last six years owing to the conduct of the defen- dants. Judgment, therefore, would be for plaintiff for the amount stated with costs. Notes from the Coalfields. [Local Correspondence.] South Wales and Monmouthshire. Alleged Illegal Deductions from Miners' Wages—The W inborne Royalty Case Result—Slump in Shipping Profits. The motion by Mr. E. Jones, M.P. for Merthyr, designed to secure that workmen’s institutes shall be exempted from duty, affects South Wales probably more than any other part of the country, for nearly every part of the district has its miners’ institute, “ erected mainly by contributions of the workmen.” Mr. Jones has cast his motion in wide terms, and necessarily so, some of the institutes having the only public halls available for general use; and these, there- fore, serve materially as sources of income. The idea is that, notwithstanding financial prosperity, the exemption shall operate in all cases. The Mynachdy Company, Ynysybwl, have been summoned at Abercynon for the recovery of money alleged to have been illegally deducted from a workman’s wages, and the issue affected nearly a hundred of the firm’s employees. The facts were that the weighing machine had been out of order; the men had been, therefore, overpaid, and the deductions made later were in respect of the alleged over-payment. Judgment was given for the men. A second case was of unusual interest, both because of the parties concerned and the issue involved. Lord Wim- borne leased eight acres of minerals, and these formed part of the takings of Bryndu Colliery, a clause in the lease of the eight acres providing for continuous and uninterrupted working. The lease came by assignment to Miss Talbot, of Margam, the owner of vast mineral estates, and largely interested in Port Talbot docks and town. This lady is dis- tinguished for her philanthropy, and to avert stoppage of the colliery, which is in Llangynwyd parish, with the conse- quent throwing of a large number of men out of employ- ment, she carried on the colliery for some years at a heavy loss—no less than £90,000 in all; but ultimately closed it down. The action was before the court in December, and now came before the official referee on the question of damages. Although plaintiff had contended at the trial that the colliery had been finally abandoned, and that damages should be assessed once for all, the judge did not take that view; and the matter came before the referee upon defen- dant’s contention that plaintiff could only recover damages as from time to time, and not recover future damages, as she had not repudiated all the covenants under the lease. It was now submitted that plaintiff was entitled only to the minimum rent, £50, and that defendant had been perfectly justified in ceasing to work. Expert evidence was called-— Mr. H. T. Wales, Mr. Wright, and Mr. Martin—as to the practicability of continuing operations; and on the other side it was stated that even if the working had continued the Wimborne coal would not have been reached, and that, therefore, plaintiff was not entitled to more than the mini- mum rent. Mr. Arthur Lawrence, for the defence, said the colliery, as a whole, could not be worked at a profit; and Prof. Galloway also gave evidence. After three days’ hear- ing the official referee decided that Miss Talbot was bound by the lease to work out all the Wimborne coal; and he assessed damages in favour of plaintiff at £1,854, up to June 25. As indicating the slump in shipping profits, the report of Tatem’s Steam Navigation Company, which owns a fleet of 17 vessels, shows a working profit of £120,648, as compared with £363,139 for the year to June 1913—a decline of more than two-thirds. The report points out that for the first six months of the financial year freights were good, but since then the rates have been unremunerative. The falling off in freight rates is not entirely responsible for the big decline in profits, inasmuch as costs have gone up, particularly as regards repairs, which are estimated to be about 40 per cent, higher than they were two or three years ago. Recently issued figures go to show that the Welsh tinplate makers are steadily regaining trade which was captured a few years ago by the Americans. Official reports show a con- tinuous decline in the export of American plates, but competition is threatened from another quarter, for there is a suggestion to establish works in Norway, and to put a tariff on tinplates. The tinplate imports of Norway were 32,922 tons in 1912 and 28,522 tons in 1913. The exports from South Wales to the country were 31,503 in 1912 and 25,166 in 1913. It is probable that there will be a demand for an additional tariff to be raised in Germany, where by the end of the year the capacity of the works will be 14,000 tons per month. Messrs. Nixon, of Nixon’s Navigation, recently appealed against the judgment of the Inland Revenue Commissioners regarding the valuation of the company’s property in the parish of Llanwonno, Glamorgan. A referee was appointed and the appeal was successful. On Monday Mr. Pease, on behalf of the company applied to Mr. Justice Scrutton to have the five orders of the referee made orders of the court, so that the costs could be taxed—the Inland Revenue authori- ties having failed to agree on this point. The referee had made an order as to the valuation which carried the costs, and there was no opposition to the application. The judge made the order, observing that under the new rules no such application would be necessary in future. The recently issued census returns show that the number of men and women engaged in Wales working in and about mines, and dealing with the product thereof, was 150,694 males and 92 females; 12,000 men were engaged in tinplate manufacture and 2,000 in copper manufacture. In Mon- mouthshire there were 53,500 miners and 86 women engaged in or about the mines. It was reported at Swansea last week that a new company is negotiating for the acquisition of the Carbryn Anthracite Colliery, Pantyffynon, and that in the event of the deal going through, it is intended to expend £20,000 on develop- ing the lower measures. At Ystrad County Court, on Tuesday, Judge Bryn Roberts spent five hours hearing a claim by Thos. Perkins against the Blaenclydach Colliery Company for £11 6s. for driving 98 yards of stall headings. Plaintiff claimed 2s. a yard and 45 per cent., and the claim was based on the price list. In the price list, however, there was no item dealing with the claim. Two turnings had been made in the heading, and it therefore became an ordinary stall heading, for which pay- ment should be made at the usual rate. For the defence it was said that stall headings were not in the price list, nor was there any custom. The man had been paid for all he had done, but now that the company for their own conveni- ence brought coal through the heading, plaintiff claimed that he was entitled to 2s. a yard. In giving judgment for the plaintiff his Honour said that the case had completely broken down, and that the company’s books produced were con- clusive. The Welsh Navigation Coal Company are erecting at Tonyrefail, extensive washeries, coke ovens and by-product plant. The washeries will be driven by electricity, and 750 tons can be dealt with in eight hours. The works will be a new industry for the district, and over 100 men will be employed. The mining industry is largely represented in the list of new magistrates just issued. Among those honoured are :— Mr. Robert Gibb, managing director of the Glanavon Garw Colliery, Gibbs’ Navigation Colliery, and Glynogwr Colliery; Mr. H. Wallis, director of the Great Western Colliery Company Limited and of Locket’s Merthyr Collieries (1894) Limited; Mr. Joseph Davies, of Messrs. Joseph and Hailey, coal exporters, and joint secretary of the Coal and Shipping Exchange, Cardiff; Mr. D. M. Rees, chairman of the North Rhondda Steam Coal Company Limited; Mr. John Thomas, colliery agent to the Standard Collieries; Mr. Thomas Evans, director of the Ocean Coal Company Limited; Mr. J. John, who controls the Llwynon Colliery. Several well-known miners’ agents have also been included, amongst whom may be mentioned Mr. W. Jenkins, Mr. W. Brace, M.P., Mr. Watts Morgan, Mr. T. Lucas, and Mr. Vernon Hartshorn. Northumberland and Durham. New Rescue Station at Newbiggin — Homes for Aged Workers. The new rescue station which has just been opened at Newbiggin Colliery has been erected by the colliery com- pany’s own workmen, and cost about £400. The plans were prepared by Mr. T. J. Cripps, the colliery engineer. On the ground floor there is accommodation for an ambulance van, and the rescue apparatus is also stored on the ground floor. The smoke helmets are of the “ Durham ” type. Also on the ground floor is the ambulance room, replete with everything necessary for injured persons. Upstairs are class rooms and rooms for reading and recreation. There is a movement to form an ambulance brigade at the colliery. An explosion took place on Sunday night at the Crofton Pit, one of the Cowpen group of collieries. Four men working in the Low Main seam of the pit were burnt more or less seriously by the explosion. One of the finest miners’ halls in the county of Durham is undoubtedly that opened at Easington Colliery on Satur- day by Mr. T. H. Cann, an agent of the Durham Miners’ Association. The structure itself cost about £5,000, and the furniture and fittings £1,000. The main hall has a seating capacity of 1,100. The committee rooms are also on a large scale. The foundation stones of ten cottages for aged miners were laid at Trimdon Grange on Saturday. The homes have been built by the workmen of Trimdon Grange and Deaf Hill, and are built on land given by Mr. John Wood, of Coxhoe Hall, who is one of the owners of the Deaf Hill Colliery. The Trimdon Grange Colliery owners have also made a subscription of fifty guineas. The miners, mechanics and enginemen connected with the Wearmouth and Hylton collieries have decided to support a scheme for providing homes for aged mine workers in the neighbourhood. The company has been approached with regard to land for the purpose, and both the chairman and Mr. Parrington, the agent, are said to be willing to help in that direction. The North Bitchburn Coal Company Limited, of Darlington, have recently decided to instal at their Randolph Colliery, Evenwood, Co. Durham, a mixed pressure turbo- generator, and to drive the underground and surface machinery at this pit by electricity, and also to convey the current by overhead cables to their Gordon House Colliery, and subsequently to the Hylton sinkings. By this utilisa- tion of exhaust steam, the company anticipate a considerable saving in running costs. The work is to be carried out under the direction of Messrs. W. C. and K. A. Mountain, consult- ing engineers, of Newcastle-on-Tyne. A Local Government Board enquiry was held at Gosforth last week relative to the appeal of the Seaton Burn Coal Company against the decision of the Gosforth Urban District Council in regard to the provision of water closets in the company’s houses at Gosforth. Over 40 houses owned by the company were affected by the ultimatum of the Council. Mr. C. M. Morton, colliery manager, stated that the houses were an unprofitable concern at present and, with the additional expense of installing the water system, the houses would be closed and many men would have to live at Forest Hall. A diamond jubilee in the coal trade is that which is being celebrated by Messrs. Sauber Bros., Hamburg, the well- known German importers. The firm’s agents in Newcastle are Messrs. T. H. and J. J. Catcheside and Company. The firm was founded on July 6, 1839. Cumberland. Purchase of Ellenborough Colliery. Tt is stated on good authority that negotiations have been entered into for the purchase of the Ellenborough Colliery, near Maryport, which was closed down in January last, owing to lack of capital. Mr. Elliott, of the firm of Dunford and Elliott, ship owners of Newcastle, Middlesbrough and West Hartlepool, is the principal mover in the scheme, and preliminary arrangements are being directed to the formation of a syndicate, and in the event of this being successful they will proceed to the allotment of the shares. The capital of the new company will be £150,000, and they propose to widen and deepen the two existing shafts, to equip the colliery with the most modern machinery for a large output, and the erection of a new set of by-product coke ovens. Towards the end of last year a scheme for the reconstruction of the colliery was in progress, and an attempt was made to form a company with a capital of £200,000. but in January the pit ceased working, and the reconstruction scheme fell through. Several local people have also been approached and the promoters have been favourably impressed with the scheme. Mr. J. Dickinson, secretary and manager of the North Lonsdale Iron and Steel Company (Limited), it is stated,
