212 THE COLLIERY GUARDIAN July 24, 1914. which allow a satisfactory connection or anchorage directly to the old bulkhead. In comparing the advantages of the various types of bulkhead construction, the ease with which timber for timber bulkheads can be transported over caved and broken ground is an important factor favouring that type, as is the comparatively low cost of timber con- struction and its flexibility and advantageous application under difficult conditions. In timber construction, how- ever, it is impossible to anticipate the re-use of materials employed. Masonry construction is necessarily expen- sive. For extensive final or pillar mining the masonry type of bulkhead possesses attractive advantages, and may in future work be developed so as to present the greatest ultimate economy. Heretofore such construc- tions have been built primarily for ventilating purposes, being later used advantageously in mine filling. Bulkheads made by blasting the roof and floor are an extension of the plan of supporting the roof in this way. With a considerable quantity of small coal and fine dirt available it may be possible to construct a barrier of blasted rock across a comparatively flat working place and, by placing a sufficient quantity of this fine material at the inner face of the rock barrier, to form a filter that will eventually retain the filler. Judging from the apparent effectiveness of general roof falls as bulkheads, this type of construction should be efficacious and economical in sections considered inaccessible as regards the construction of either timber or masonry bulkheads, especially in places where the roof and bottom are softer than the usual sandstone of the anthracite mines, and where the opening is less than 6 ft. high. Air and water cause newly broken-down shales and “ slates ” to slack or disintegrate, consequently the voids or interstices in such a bulkhead rapidly fill up and the barrier becomes less pervious. Brick, concrete and other masonry bulkheads are the most expensive, but can be made to serve a double use, as ventilation stoppings and subsequently as filler bulkheads. In many mines where the workings are extensive, it is necessary to construct stoppings of masonry to ensure a sufficient quantity of air reaching the working faces. Bulkheads of masonry are most practical when filling is conducted on the panel or dis- trict system. In such practice each panel or district is separated by building bulkheads across openings in the boundaries only; no bulkheads are constructed at the foot of chambers or rooms. Timber bulkheads would be impracticable, owing to the long interval between the first mining and the time when filling can be safely undertaken. (To be concluded.) Notes from the Coalfields.

The second session of the joint diploma mining course, of the South Wales and Monmouthshire School of Mines, in association with the University College, Cardiff, will commence on Tuesday, October 6, 1914. The entrance examination for this course will be held on Tuesday, September 22, 1914, at the School of Mines, Treforest. Special part-time courses for colliery managers, surveyors, chemists, mechanics, and electricians, will commence at Treforest, on October 6, 1914, and at Crumlin on Novem- ber 2, 1914. For particulars application should be made to The Principal, School of Mines, Treforest. Mr. Keir Hardie, M.P. for Merthyr, upon the result of the prosecutions concerning Senghenydd explosion, decided to question the Home Secretary as to the probable action which his Department may take in the matter. These decisions were reached on Saturday last, and out of the 21 summonses that were issued (17 being against the manager and four against the company) it transpired that the original 17 were reduced to 10, and that fines were imposed in five of them. All the summonses against the company were dis- missed. The total amount of the fines imposed upon the manager and agent was £24, with 25 guineas costs. The prosecution had been instituted by the Home Office, and was, in the main, for breaches of regulations. The cases were heard at Caerphilly, and the magistrates found that the defendant company had taken all necessary steps to enforce the Act and the rules, having appointed a competent certificated manager; the directors took no part, nor did they interfere in the management. With regard to the question as to clearing coaldust from the roadways, the decision of the bench was entirely in favour of the manager, the magistrates being of opinion that he had done all that was reasonably practicable to prevent accumulation of dust, and the information against him under this head was, therefore, dismissed. Upon the summons for not providing adequate means for reversing the air current, a conviction was recorded, and the fine in respect of it was £10. It was shown that the original date was January 1913, that an extension was granted to September 30 of that year, but that on October 14 the work had not been carried out. One of the summonses alleged that safety lamps of the approved type had not been pro- vided, but the magistrates found to the contrary, it being admitted even by the prosecution that the lamps were of approved type, though they complained that the glasses in use had not been approved. It was shown, however, that defendant had done all he possibly could to procure glasses of the approved type, the manufacturers being unable to meet the demands; and the summons under this head was, therefore, dismissed, as was also a summons for not causing measurements to be made of the quantity of air in the mine and every split at the points. Cardiff Chamber of Commerce had before it on Wednesday the question of alleged preferential treatment in respect of coal shipment at the docks, and it was stated that a com- mittee of the chamber hoped very shortly to meet repre- sentatives of the three local dock companies upon the ques- tion. By a communication from the Coal Trimmers’ Union it was understood that these men would not be working on Monday or Tuesday, August 3 and 4. With regard to the effect of the engineers’ strike upon the coal shipping trade, it was reported to the Cardiff executive of the Shipping Federation on Wednesday that at that time eighteen vessels were held up by the strike of fitters in the ship repairing yards, and that seven loaded vessels were also stopped. In this connection it has to be noted that the committee of the central body, meeting in London on Thurs- day, had under further consideration the question of laying up tonnage, and that although this was originally proposed because of the depression of rates of freight, it is now being more generally favoured, because of the influence it may have upon the engineers’ strike. The laying up of vessels would make more engineers stand idle, and thus a greater number would be available for engagements on vessels affected by the strike. It was reported to the Glamorgan Education Committee on Monday that agreement had been reached as between that authority and the coal owners with regard to control of the schools of mines. A new board was suggested, to consist of 11 representatives of public authorities and 11 representatives of the coal owners, the latter also appointing the chairman; so that the full board would number 23. These would have jurisdiction over the three mining schools of Treforest, Crumlin, and Swansea; and in submitting the proposal to the committee, Aiderman Williams said that, seeing the coal owners bore the whole expense of these schools, it was a very fair arrangement. The principle of the scheme was approved by the committee, but a Labour member intimated dissent. The idea that wayleave payments constitute a “ right,” and that alternative access ought not to be allowed to extinguish that “ right,” found further expression on Friday in the Parliamentary committee room, when the Great Western Railway Company’s Bill for new colliery lines in the Neath Valley was under discussion. The managing director of the canal company gave evidence that £120 a year now received from one colliery company in respect of coal passing over the canal by a bridge would be lost if the new Bill were passed, inasmuch as there would be direct connection of the colliery with the new railway; and, when the committee’s decision was announced, counsel for the canal company asked if they had considered this matter of the loss of wayleave income! Another opponent of the Bill had (as previously reported in this column) lodged objection because he would lose some hundreds of pounds annually in respect of wayleave, and he had no other ground of objection. The committee ignored both these cases of oppo- sition, and found the preamble of the Bill proved. The promoters showed that a large undeveloped coalfield exists which would not be worked unless the new railway be con- structed; and that upon the area being opened up employ- ment would be found for thousands of men. Among those who were called as witnesses in support of the Bill were Mr. T. Jones, managing director of the Rock Colliery, Glyn Neath; also Mr. W. J. Stephens, director of the Ynysarwed Colliery; Mr. J. Roberts, mining engineer; and Mr. R. L. Sails, colliery manager. The actuary who was appointed to report upon the cir- cumstances of the Senghenydd relief fund has presented a statement to the committee which shows that it will be necessary to reduce by Is. per week the allowances at present being made to beneficiaries. Associated with the Senghenydd fund is the Glynea Colliery fund. The actuary is Mr. Neison, who states that on June 30 the total number entitled to relief was 765, and of these 213 were widows and 503 children. There were also other dependants. At present widows received 10s. per week, children 5s. per week until a specified age, and the different dependants (mostly mothers) from 2s. to 10s. per week. Mr. Neison had estimated an income from interest at the rate of 3 per cent, per annum, and the capital standing to credit of the fund on the date mentioned was £116,300. Upon the existing basis of benefits paid, the actuarial “ liabilities ” worked out to a total of £140,568, leaving, therefore, an estimated ultimate deficiency of £24,268. He recommended, therefore, that the allowances to widows be reduced from 10s. to 9s. per week, children from 5s. to 4s., with certain other reductions. The report was accepted by the committee, and it was decided that in future the payments made should be those suggested by Mr. Neison. The Status Investment Trust is a South Wales organisa- tion associated directly with collieries and allied under- takings ; and at the annual meeting on Friday, the chairman (Mr. J. Davies) stated that among their operations during the year they had assisted in providing new capital for collieries, public utility companies, railways, and docks. They confined their operations to South Wales; and every one who knew the district had complete confidence in its further prosperity. Collieries now being sunk in the immediate neighbourhood of Cardiff would bring on the market additional outputs totalling 7,000,000 tons annually; and there must be consequent extensions of railways and docks, provision for housing tens of thousands of workers, with municipal and other developments. Uneasiness as to labour probabilities was lessened by the more favourable relations in the railway world, which must have good influence towards amicable settlement of the new wage agreement for the colliers. The important action by coalowners against the Glamor- gan County Council was mentioned in the High Court on Tuesday. It relates to charges incurred by the coalowners for board and lodging of police in the Rhondda during the strike, when large reinforcements had to be brought in because of the Tonypandy riots, and to safeguard property. The issue raised as to liability for maintenance of the police is of great public importance. Mr. Salter, K.C., for the Glamorgan Coal Company, who claim £23,000 from the County Council, stated to the court that questions of fact and of law were involved, and the hearing would take some time; and as the case had already stood over for a long while, he hoped it would be taken before the vacation. Other counsel preferred that the hearing should stand over; and the judge, who said there were other lengthy cases to be finished, made an order for the action to go over till next sitting. During the past six months there has been a heavy decline in the imports of pit wood, the figures being 799,119 loads, as against 854,676 loads in the first half of 1913; one reason for the decline being that very large quantities were imported at the end of last year. For the upward move- ment in price—which has characterised the last 10 years— many reasons are given, such as the working out of the nearer forests, scarcity of labour, etc.; but whatever the cause, the increase has been a serious matter to colliery proprietors of South Wales. There have been complaints, too, that the stipulated 50 per cent, of 9 ft. lengths has not been maintained. This year’s prices ranged from 19s. 6d. to 22s. 6d., as compared with 18s. 6d. to 23s. last year. Mr. E. A. Creed, until recently agent for the Windsor Colliery, Aber Valley, on Saturday received a presentation from the officials and others. It took the form of a book cabinet; and he was entertained at a banquet in the Panteg Hotel. Northumberland and Durham. Hewing off the Side—Presentation to Mr. J. G. Weeks— The New Pit at Backworth. Considerable damage was done to the shaft at Twizell Colliery last week, owing to a tub becoming loose in the cage. The buntings and skids were so much damaged that the nightshift men could not descend, and the pit was idle next day. When the chairman of the Seaham Petty Sessions fined two miners for hewing off the side at the New Seaham Colliery, he stated they had had quite a number of similar cases recently and, if the £2 fines imposed on that occasion did not prove effective in stopping such a dangerous prac- tice, the punishment would have to be increased in future. Mr. Coroner J. Graham, who is one of the best known figures in Durham County, last week entered upon his 82nd year. Probably few men have taken part in so many mining enquiries as has the aged coroner. Despite his age, his summing up and quickness in seizing upon the salient points at an inquest are still remarkably great. His know- ledge of mining work has stood him in good stead, and at the enquiry into the great West Stanley disaster some years ago he displayed not only powers of endurance and patience, but an amount of mining intelligence which surprised some of the Home Office officials. The members of the Hebburn Colliery Ambulance Class hold Mr. R. G. Wilson, son of Mr. E. Wilson, the colliery manager, in high esteem. Mr. Wilson has acted as secretary, captain and instructor of the rescue class, and he is now secretary and chief officer of the Hebburn Colliery Ambulance Class. To mark their appreciation of his services on behalf of the class, the students have presented him with a suitably inscribed gold watch. The Wallsend and Hebburn Coal Company has provided the rescue class with a rescue station, equipped with observation corridor, lecture room and complete rescue apparatus. At the meeting of the Colliery Undermanagers’ Mutual Aid Association, held at Washington last Saturday night, an excellent paper on the “ Statutory Duties of Deputies,” was given by Mr. Dawson. The inquest on the men killed in the Crofton Pit explo- sion at Bly th has been adjourned until August 13, as the principal witnesses, injured men, are too ill to attend the enquiries. The grounds of Laird’s House, Bedlington, were the scene of a pleasant gathering on Tuesday afternoon, when a garden party was held at which a presentation was made to Mr. John G. Weeks. Mr. Weeks is one of the best known figures in the Northern coalfields, and his resignation from the position of agent for the Bedlington Coal Com- pany was the reason for the gathering on Tuesday after- noon. It was felt that the occasion was a fitting one for all who had come in contact with Mr. Weeks to express their esteem and appreciation of him. The 50 guests who assembled represented members of local bodies, miners’ lodges, colliery officials, and the Bedlington Coal Company. After an excellent luncheon, Mr. C. W. C. Henderson, of the Riding, Hexham, one of the owners of the Bedlington Collieries, made the presentation to Mr. and Mrs. Weeks, on behalf of the colliery officials, workmen and general public. It consisted of an illuminated address, a grand- father’s clock and a writing bureau. The writing bureau is from a design drawn by Mr. Weeks himself. The two Misses Weeks, young ladies who are deservedly popular in the district, were presented with gold bracelet watches. Col. Bates, of Hexham, supported Mr. Henderson, and other guests made speeches which spoke volumes for the esteem in which Mr. Weeks is held. Mr. Weeks is an ex-president of the North of England Institute of Mining and Mechanical Engineers. The sinking operations at the Backworth Coal Company’s Prosperous Pit, Benton Square, have been completed so far at it is at present intended to proceed, the Bensham seam having been reached. If necessary, a large field of high- class coal can be tapped by the shaft. A large amount of machinery is being erected at the pit-head, and the shaft will soon be ready for use. The old “ C ” Pit, at Back- worth, which was closed and dismantled some years ago, is also to be re-opened. Cumberland. Sulphuric Acid Plant at Workington. The steamer “ Artificer ” left the Senhouse Dock, Mary- port, on Friday, for France, with 250 tons of benzol, the first consignment that has been shipped from the new works at the head of the Maryport dock. The dull state of the Cumberland rail trade is reflected in the reduction of the working week at Moss Bay Steel Works by two days from this week. The furnaces are unaffected. The number of furnaces in blast in West Cum- berland is 14, and in North Lancashire eight. The sulphuric acid plant which the Liverpool firm of Carmichael and Guillaume have installed, under the personal supervision of the latter, at Messrs. Brotherton and Company’s chemical works, in Lonsdale Dock*, Workington, in proximity to the tar distilling plant, which has been working effectively since January 1, was put into operation on Saturday, and is giving every satisfaction. It is known as the vertical tower system, and represents the latest methods of manufacture. Workington enjoys the distinction of being the first place in this country and the third in the world to have this improved type of patent plant. The other two installations are in Germany and India. Sul- phuric acid is produced from spent oxide, a product of the gasmaker: also from pyrites, mined in Spain and elsewhere. Spent oxide is the present source of the Workington product. Mr. Graham has resigned the secretaryship of the Cumberland Colliery Officials’ Association, and Mr. W. R. Cottier, Kells, has been appointed to the position pro tern.
