March 16, 1917. THE COLLIERY GUARDIAN. 531 THE STATE AND COLLIERY FIREMEN. At the annual meeting of the Ashton-in-Makerfield (Wigan) branch of the Lancashire and Cheshire Colliery Firemen’s Association, Mr. Thomas Eden, the branch president, delivered an address on the question of “ The State and Colliery Firemen,” in the course of which he replied at some length to the remarks on the same 'sub- ject by Mr. Mason, colliery manager, of Wigan, already published in our columns/'1'' Mr. Eden pointed out that Mr. Mason said if he were asked to describe the char- acter of the inventor of the original proposal for State- paid firemen, he would say that he was a most unreason- able and illogical being, and absolutely ignorant of the practical and economic life of present-day firemen, and he further said that he would venture to express the opinion that the present-day fireman would never think of such a thing. The economic conditions of the colliery firemen to-day, said Mr. Eden, were such that they tended to make him go, or influence him, in the wrong direction so far as safety w’as concerned. He con- tended that colliery firemen throughout the country were being dismissed, not on the plea of incompetence, but for any trifling thing that occurred through the wide field of their work, which ranged from skill as a mechani- cal engineer to the work of a pony driver. It did not matter what occurred, if there was something wrong, it was the colliery fireman who was spoken to, and to a very large extent it was the fireman who was held responsible; the onus was upon him, and it was he who was dismissed, and when such a case was brought up they were invariably met with the cry that it was incom- petence. No provision was made for the extra work which had nothing to do with their statutory duties, but which they were called upon to do. The fireman had to be able to measure work done in his district, and he must be capable to fire shots in his district, but neither measuring work done nor firing shots must in any way be allowed to interfere with carrying out his statutory duties under' the Goal Mines Regulation Act. The speaker said he had travelled Lancashire and Cheshire as much as any colliery fireman in Lancashire, and, with the exception of their general secretary, he was not pre- pared to take a second position to any man outside or inside their organisation so far as his knowledge of the colliery fireman’s position went, or the practical work- ing conditions of colliery firemen in the county, and right through the county and the country. Owing to the economic condition of the colliery firemen, he was held responsible by the management to a very large extent for the amount of coal coming out of his dis- trict. If the “ gets ” went down, the fireman had to explain. The “ get ” seemed to get on the mind of the colliery managers and the under-managers, and the fire- man was at the bottom of the whole thing. Yet as far as his real duty was concerned, the “ get ” had abso- lutely nothing to do with it. The fireman was held responsible to a very large extent not only for the “ get,” but for the mine work done by individual men in the district over which he had supervision. He had known men stopped at a minute’s notice because they had not sufficient mechanical skill to report about the pump or engine that had broken down in a shift over which they had control; he had known them to be dismissed because they had not known all the circumstances apper- taining to a stoppage on the haulage, and also at a moment’s notice because they had made a conscientious report in the daily report book. In some instances, the organisation had endeavoured to get the cases into the law courts, but whenever they had taken that stand— and they did not like to do it; they did not like to quarrel with the management — and had put in for damages for illegal dismissal, in less than three posts they had had the demands and fees returned to the organisation. So long as they knew such things were taking place, they were bound to do something towards stopping it, and they did honestly believe that if the firemen were placed in an independent position, they would be able to reduce the number of accidents which were taking place in mines. They w7ere told by Mr. Mason that they had the remedy in the rules, and that they had the assistance of the manager and the under- manager to help them to surmount any obstacles which might occur. They were told they could get their remedy through their association, or they could call in the inspector to put things right. That was just where the bother came in. Mr. Gill, who was a practical colliery fireman, and had occupied that position for pro- bably as many years as he (the speaker) was old, moved the proposition they were now discussing at the last Trades Union Congress, and stated cases to show what they themselves all knew. It was necessary, however, that those things should be spoken of in order that other people might know as well as themselves. Mr. Mason said that no practical fireman would think of supporting such a proposition as was before them. Had he known as much of the history of the movement as the speaker (Mr. Eden), Mr. Mason would never have made such a statement. Mr. Eden said he himself had sat round a table where representatives had been present represent- ing upwards of 20,000 colliery firemen in Great Britain, and he had heard the question debated, and when the vote came not one man of them all was opposed to the idea. If Mr. Mason had known that the whole body of colliery firemen had declared in favour of the proposition, he certainly would never have made the statement that no practical body of colliery firemen would have sup- ported the movement. The proposition had had an absolute unanimous support from every miners’ leader in Great Britain, and some of those men had so far won the respect of the nation that at the present time they were in the British Cabinet. Had those men no prac- tical knowledge of the economic condition of the colliery firemen? He (the speaker) told them that there was not one of them who was opposed to the proposition, * See Colliery Guardian, December 8, 1916, p. 1110. and there were a great number of men in the House of Commons who, apart from the miners’ leaders and those in sympathy with them, ’were in favour of the move- ment. They were told by such an eminent man as Mr. Walker that 50 per cent, of the accidents in mines were avoidable; and if they were avoidable, who was the man who could avoid them? The fireman. And he (the speaker) said : Give the fireman an economic position to enable him to do so. The fireman’s present economic condition, impaired his judgment, and he might hesitate to stop a road, because he would have to withdraw men. Mr. Mason said they must not forget that they were human. They were human, and that was why they asked for better conditions. State pay would not make firemen a set of slackers. He added that they suggested- the establishment of a district authority, to which all applications for appointments as firemen and inspectors should be made; that they should be State servants, and controlled by the district mining board; and that all complaints, grievances, and appeals should be considered and decided by the district mining safety board, to be composed of an equal number of representatives of the Colliery Firemen’s Association, the Miners’ Asso- ciation, the coal owners, etc., and presided over by a divisional inspector. He claimed that the system would work successfully. All they asked really was that there should be a change in the jurisdiction, which would put them under the Government, and he believed that with a little bit of tact, what they wanted could be accom- plished. He asked all firemen to give the proposal their whole-hearted support. A resolution in the same terms as that passed at the Trades Union Congress was unanimously adopted at the close of the address. SAMPLING DELIVERED COAL.* By G. S. Pope, ^Continued from page 485.J Sulphur and Clinker. Sulphur is commonly present in coal in combination with iron or other elements. For a long time it was thought that the sulphur formed clinker, but recent investigations point to the fact that there may be no difficulty from clinker in burning coal containing as much as 5 per cent, or more sulphur. The relative propor- tions of iron, sulphur, lime, alumina, silica, etc., in the ash affect its fusibility, whereas the method of firing and the rate of combustion are important factors in the for- mation of clinkers. The exact relation of clinkering to the constituents of the ash is not known so well that one can definitely predict from an analysis of the ash whether a coal will or will not clinker. Contractors, however, are required to specify the sulphur content, so that standards for the coals to be delivered may be established. Both the sulphur and the volatile matter content should be used to classify coals and to identify the coal guaranteed. Variations indicating the substitution of an unsatisfactory coal should be considered cause for rejection of the coal or for cancellation of the contract. Need of Care in Sampling. Persons without experience generally select a sample better than the average run of the coal delivered. Occa- sionally, a lump unusually free from layers of slate and impurities, and representing the best coal in the lot rather than the average, is selected. After being broken it is shipped to the laboratory in a cloth sack, so that it loses moisture during transit. The analysis of such a sample necessarily indicates a value higher than that of the coal delivered. As a quantity of coal may vary greatly in composition, containing not only what may be termed coal proper with certain more or less constant impurities, but also slate, pyrites, and bony coa], a lump may be anything from almost pure coal to material without fuel value. Hence the analysis and test of a single lump may indicate a composition greatly different from that of the coal at hand. It is well to remember'that, as the larger lumps of coal roll down and collect near the bottom of a pile or load, a sample taken entirely from near the floor does not always fairly represent the whole. In spite of every precaution taken to prevent loss of moisture during the collection, preparation, and analysis of samples, it .is certain that loss of moisture may occur; also there may be too little or too much slate, bony coal, or other foreign matter collected in what is otherwise a truly representative gross sample, so that the- determi- nation of the heating value or ash content does not strictly agree with the actual value of these factors in the coal delivered. However, an experienced collector, by using good judgment and following the general direc- tions given for collecting and preparing samples, can obtain samples so fairly representative that the results of the analyses are reasonably accurate. The sugges- tions that follow are presented for the guidance of those who wish to send representative samples to a laboratory for analysis and heating value tests. Directions for Sampling. The number of pounds to be taken as a gross sample to represent a given lot of coal varies with the character and condition of the coal, and not with the amount of coal to be sampled. The character and proportion of the bony coal, slate, etc., and the size of the particles of both coal and impurities are the governing factors. It is therefore evident that sampling should not be left to an inexperienced person, but should be done by one who is thoroughly familiar with the significance of these factors, and has some knowledge of the coal to be sampled. As a result of experiment, it has been established that a gross sample of approximately 1,0001b. is sufficient to give reliable results for coals comparatively easy to sample; that is, coals relatively^ free from the * From United States Bureau of Mines Bulletin 116. ” extraneous ” impurities. It may be necessary to collect larger gross samples, even 1,5001b. or more, for coals containing a considerable proportion of impurities in large pieces, or large lumps of coal' with streaks of bone, slate, or pyrites, or sulphur balls and lenses. For convenience, however, and to avoid long storage of the samples, the Bureau of Alines considers it advisable that one sample of 1,0001b., or more, should be collected weekly in the case of Government contracts calling for more or less regular deliveries each week. In sampling cargo deliveries of 5,000 and more tons, the Bureau of Alines collects from 3,0001b. to 4,0001b. of coal as a gross sample. In order that the preparation of the samples may proceed while the cargo is being loaded, after approximately 500 1b. has been collected, it is reduced to a quantity convenient for mailing to the laboratory, and each succeeding 5001b. is likewise reduced. The samples may, however, be mixed in the laboratory, and only one analysis made to represent the cargo. The best opportunities for procuring representative samples are afforded while the coal is being loaded into or unloaded from railroad cars, ships, and barges, or while it is being dumped from wagons. Once the coal is stored in piles or bins, or loaded on cars or vessels, the procuring of representative samples is practically impos- sible, unless the whole quantity of coal is immediately handled again, and the conditions for sampling become favourable. When coal is being loaded . into or unloaded from wagons, railroad cars, ships, or barges, a shovel or a specially-designed tool may be used for taking portions or increments of 10 to 30 lb. to make up the gross sample of coal. As the size of the increments should be governed by the size and weight of the largest pieces of coal and impurities, increments of more than 301b. may be required for coals containing large pieces of coal and impurities. If one chute or conveyor is used for delivering a con- siderable quantity of coal to or from wagons, cars, or ships, it may prove expeditious and economical to devise a mechanical means for collecting portions from frac-, tional parts of the discharged coal, or continuously deflecting a portion of the coal as it falls down the chute, or diverting from the conveyor definite portions of coal, and thus mechanically and automatically collecting the gross sample. Excellent opportunity is afforded for pro- curing representative samples if the entire consignment of coal is crushed immediately after it is weighed and delivered, for then the samples can be collected from the crushed coal. If the coal is conveyed from the crusher by a conveyor, means can be devised for mechanically and automatically diverting from the conveyor definite portions of coal to make up the gross sample. The portions should be regularly and systematically collected, so that the entire quantity sampled will be represented proportionately in the gross sample, which should contain the same proportion of lump coal, fine coal, and impurities as the coal delivered. As soon as the portions are collected, they should be deposited in a receptacle having a tight-fitting lid provided with a lock. A gross sample taken by hand from coal delivered by wagon should consist of shovelfuls of coal taken from the first, second, or third wagonload as it is being dis- charged, the number of shovelfuls taken and the loads sampled being dependent on the number of loads which the gross sample is to represent. If the coal is discharged immediately into a crusher, it is preferable to collect shovelfuls of the crushed coal. Samples taken from railroad cars should not be limited to a few shovelfuls of coal procured from the top of a car, for the size of the coal and the proportion of foreign matter may vary from the top to the bottom of the car. The only way to obtain a representative sample is to take a number of shovelfuls or portions of coal from different points in a car, from top to bottom and from end to end, while the coal is being loaded or unloaded. When a shipment of coal is sampled at the mine, shovelfuls or portions of coal should be taken systematic- ally as the coal is loaded into the railroad car, and with such regularity that the sample will represent the entire carload. The samples should be taken after the coal has been prepared for market; that is, if the coal is passed over picking tables, or pickers are employed on the car to remove the impurities from the coal, the samples should be taken only after the coal has had its final preparation. When coal is being sampled from dump cars, shovel- fuls should be taken from the stream of coal being dis- charged to the bins or ship. If the discharged coal is immediately crushed, the gross sample should prefer- ably be collected after the coal leaves the crusher. In sampling cargoes, as in sampling carloads, por- tions of coal should be takqn in equal quantities and at frequent and regular intervals, so as to represent pro- portionate parts of the consignment as a whole, either while the coal is being loaded or unloaded. The Bureau of Mines has charge of the sampling of cargo shipments of coal to the Isthmus of Panama for the Panama Railroad Company. The coal, which is loaded from piers at Hampton Roads, Norfolk, and Newport News, Virginia, is dumped directly from rail- road cars into ships carrying from 4,000 to 12,000 tons of coal. The method followed is to collect portions of coal from every railroad car dumped. From 30 to 601b. are taken from each car sampled, the quantity taken depend- ing on the size of the cargo. From 3,000 to 4,0001b. are usually collected as a gross sample to represent a cargo. The portions making up the gross samples are taken from the coal as it is discharged from the bottom dump cars by the use of a shovel or a specially constructed ladle. The ladle has a handle about 5 ft. long and a bowl 1ft. in diameter at the top, 9in. at the bottom, with depth of 9-1 in., and holds from 25 to 301b. of coal. To collect samples with the ladle, it is rested on the rails of the brack or on the chains that support the gates of
