In the course of the report some interesting comparisons are made between the Fleuss and other apparatus. Price Formulae. Not long ago the Belgian railway authorities decided to abolish the system of open tenders in the purchase of locomotive fuel, and to substitute for it private negotia- tion, with the use of a formula to establish the price. An interesting article, containing suggestions for a briquette formula, appears in a recent number of the Revue Universelle des Mines from the pen of M. Henry, of the Hasard Collieries. At the outset, he observes that an examination of the variations of the mean selling prices of coals sold for commercial purposes (the railway supplies being excepted) by the Hainault Collieries over a considerable period shows that, when these are compared with range of prices of Type IV. coal, there is an average ^difference of 1| fr. per ton* Type IV. is a small coal with an evaporative capacity of 7*5 kilogs. of water under a pressure of 120 mm. The ash content varies from 16 to 17 per cent. The average selling price is determined by the mines administration by estimating the value of the^quantities supplied to coke ovens and briquette factories owned by the collieries. The coals are put in at a price which is equal to one- third of the selling price of the products of these establishments, the gross profits on the manufacture of coke or briquettes being thus eliminated. The price of Type IV. coal having been established, a formula is proposed which takes into account the price of this grade of coal and the cost of pitch. This formula, which presupposes a consumption of pitch of 10 per cent, and allows 2 fr. for the cost of production, is as follows :— 0’9 (price of Type IV.) + 01 (price of pitch) + 2fr. = the price of briquettes (Type II.). There are two types of briquettes used by the railways —viz., Type II. evaporating 9 kilogs. and containing 8 per cent, of ash, and Type I. evaporating 8 kilogs. and containing from 8 to 11 per cent, of ash. Over a period of 10 years the difference in price between the two types has been 2'025 fr.; thus by adding 2 fr. to the price of Type II., the formula is also applicable in determining the price of Type I. gohtihehtal marnc, sms.

The lignite seams are computed to contain some 22 million tons. Coal Syndicate Report for April.—Total coal raised, 8,903,611 tons (7,520,197 tons in April 1912), or 342,447 tons (313,341 tons) per working day. Calculated distribution, 7,269,253 tons (6,196,470 tons), being 279,587 tons (258,186 tons), or 105'84 per cent. (98'29 per cent.) of the participa- tion. Total coal distribution of the syndicated pits, 8,871,688 tons (7,643,361 tons), or 341,219 tons (318,473 tons) per working day. Deliveries, including local sales, miners’ house coal, and supplies to pits’ own ironworks: Coal, 5,750,632 tons (4,892,043 tons), or 22,178 tons (203,835 tons) per working day; coke, 1,805,930 tons (1,595,375 tons), or 60,198 tons (53,179 tons) per working day; briquettes, 410,588 tons (325,915 tons), or 15,792 tons (13,580 tons) per working day. Ruhr Coal Market.—Business continues favourable. A large trade is being done in gas and gas-flaming coals, though the supply exceeds the demand. House coal is going off more slowly in consequence of the advance of the season. Calls for delivery in coking coals are very brisk, and the same applies to most grades of industrial fuel. Owing to the favourable state of the river it has been possible to make regular shipments to South Germany, where business is good, although the consignments are not fully absorbed —particularly in the case of house coals. Belgium con- tinues to be a fairly good customer, though the unfavour- able influence of the strike on the trade of the country is now becoming apparent. In other respects, the export business may be regarded as satisfactory. Negotiations for the renewal of the Syndicate have again cropped up, but nothing definite has been settled as yet. Coal Market in South Germany.—The favourable tone of the market has not suffered any alteration. None of the colliery districts supplying this market has any superfluity of coal available for the moment, the Saar pits being able to dispose of their output as fast as raised, whilst consumers of Belgian coals hsve suffered from the shortage resulting from the strike. The strike in Upper Silesia has not greatly inconvenienced Bavarian buyers, except that stocks have begun to run out and recourse has had to be made to the Saar and Buhr districts. The removal of all restriction on the Westphalian output has not enabled any very large quantities to be shipped up river, the home market being extensive; consequently the stocks in the Upper Bhine transhipment ports have not grown very much. Industrial consumers in general are taking their full quota, and the house coal trade is very satisfactory for the time of year, owing to the cool weather, anthracite and ovoid briquettes being in good request in view of the approaching rise in prices. Broken coke is also going off well, but the demand for small gas coke has declined, and many of the works are accumulating stocks again. THE LOHDOfl COAL TRADE. Thursday, May 29. The warm weather has had a marked effect upon the London coal market for every variety of household fuel. The demand for manufacturing qualities is at present very little affected—in fact, the volume of trade seems rather inclined to increase than otherwise, but the house coal market is unusually dull. Many of the contracts have now been settled for the ensuing year, and as the advance of Is. per ton dates from July 1st, it is anticipated that before the close of June the buying will be more freely entertained again. The premonition of the hot weather invariably stops all demand for household fuel, as the general public await the recommendation of the various merchants before ordering their summer stock, and as the actual consumption just now is confined to the regions of the kitchen, the quantity required is excessively small. On Monday’s market the attendance was fairly good, but it was speedily seen that merchants were not prepared to buy except at very reduced prices, and colliery representatives, although prepared to meet the matter to a certain extent, were decidedly opposed to the “break up’’prices suggested by some of the merchants. The restriction therefore upon the house coal market is very great. In the seaborne market however, the enquiry is still good, and some Yorkshire cargoes changed hands at fairly steady prices. Thirty-six cargoes were reported as arriving in the Thames for Monday’s market, and only five on Wednesday. The Wednesday’s market was unusually thinly attended, and it soon became apparent that only those merchants who had stock on hand to sell had attended, so that the difficulties of colliery representatives in their endeavour to secure current orders were only increased. Very little business was doing in any direction. The circulars of the “ lowest summer prices ” will not bring any return until the month has turned, and even the ordinary householder does not like to lay in his stock until August or September, but the enrol- ment of the order, though late, enables them to buy more freely, even if it has to be put into stock. The iron and steel trade seems to be falling, but arders on hand are still reported to be very heavy, and likely to keep the works busy during the whole of the summer months. Considerable satisfaction was felt in the Canning Town and Greenwich district when it became known on Wednesday that the Thames Ironworks had been bought by a firm of engineers, and that the works would shortly be open again and employing about two thousand men. The main property at Canning Town has been secured by the Great Eastern Bailway. but the installation is still to be disposed of. Many of the London merchants have adopted a novel campaign this year against the wholesale growth of gas stoves for cooking and household use, and have issued a circular pointing out the merits of the ordinary coal fire grate, and the demerits of the gas stove. The delivery trade at the various depots is reported to be exceedingly quiet, and the stables are full nearly all day as well as night. Gas coals are still in good demand. Small nuts and slacks are also finding favour, and are in good demand. Many of the larger buyers are prepared to buy forward at the present prices, so the demand seems likely to continue.
