Mr. James Duffield, of Tallentire Hall, Cockermouth, who died at Rotherham on March 7 last, aged 82 years, left estate of the gross value of £454,734 0s. 6d., of which the net personalty has been -sworn at £414,947 19s. 3d. The duties on the property at this valuation will amount to about £76,000. In the course of the debate on the Home Office Vote in the House of Commons on June 17, Mr. Thomas Richardson raised the question of the inspection of mines, with special reference to metalliferous mines and quarries. He suggested the appointment of additional assistant working men mines inspectors. COAL, IRON AND ENGINEERING COMPANIES, REPORTS AND DIVIDENDS. Allen (Edgar) and Company Limited. —• The directors recommend the payment of a dividend on the ordinary shares at the rate of 10 per cent, per annum, and a bonus of 2J per cent, for the year ended March 31, 1915, free of income-tax. Anglo-French (Transvaal) Navigation Coal Estates Limited.—The directors announce an interim dividend of 5 per cent. (Is. per share), payable to holders of the 7 per cent, cumulative preference shares. Apex Mines Limited.—The directors announce an interim dividend of 5 per cent. (Is. per share) for the half-year ending June 30. Breyten Collieries Limited.—The directors have declared an interim dividend of 8| per cent. (Is. 9d. per share) for the period ending June 30. Brown (John) and Company Limited.—The net profits for the year ending March 31 were £521,007, after providing for debenture interest, and £97,420 was brought forward. A final dividend of 10 per cent, is proposed on the ordinary shares, making. 12| per cent., subject to income-tax, for the year, appropriating for capital expenditure £100,000, adding to the reserve £75,000, and carrying forward £128,052. The Barnsley seam of coal has been proved at Rossington at the depth anticipated, and appears to be of fair section. Owing to the war, the extraction of ore was suspended at the Spanish mines, but, with this exception, there is nothing special to report in connection with the ancillary branches of the com- pany’s business. Bullcroft Main Collieries Limited.—An interim dividend of 5 per cent, on the ordinary shares of the company has been declared. Central Silkstone Collieries Limited.—Under a compulsory winding-up order against the Central Silkstone Collieries Limited, of Rock Ferry, and late of Barnsley, the report of Mr. W. J. Warley, official receiver, has been issued to the creditors and shareholders. The accounts filed under the liquidation show total liabilities of £19,030, and assets valued at sufficient to provide -a surplus of £21,097, after payment of all debts, but a deficiency of £28,902 as regards contri- butories is disclosed. The company was formed in June 1907, with a nominal capital of £50,000, to acquire as a going concern the undertaking and -all or any of the assets and liabilities of the New Wallsend Main Colliery Company Limited. Prior to the formation of the company, Mr. Andrew Anderson acquired for £5,000 all the rights, stock- in-trade, plant, machinery, utensils, and other effects of the New Wallsend Main Colliery Company Limited, together with a piece of land near Barnsley, and in June 1907, he sold all his interest therein to the company for £10,000 in shares. Debentures of £13,000 were issued, and in February 1913, as the result of an action by Mrs. J. Anderson, the court appointed Mr. Harold James, of Smithies-lane, Barnsley, as receiver for the bondholders. A few days later Mr. Wilfred Harold Capley, chartered accountant, 22, Moor- gate-street, Rotherham, was appointed as receiver in the place of Mr. Harold James, and in the following April the property was sold for £4,875. The failure of the company is attributed to lack of capital, losses on working owing to the bad quality and insufficient quantity of the coal mined, and heavy expenses incurred in the maintenance of the road in the main drift. If, as is alleged, the coal supplies of the company have been disposed of to certain persons for less than the market prices ruling at the time, there may be a claim against two of the directors for misfeasance in regard to these matters, but unsecured creditors should observe that, in the event of moneys being recovered by the company from those directors, they might be claimed by and become payable to the debenture holders, subject to any preferential claims ranking in priority. The liquidation has been left in the hands of the Official Receiver. Cortonwood Collieries Company Limited.—The directors announce an interim dividend of 5 per cent, actual. Dinnington Main Coal Company Limited. — In their annual report for the year ended March 31, the directors state the result of the company’s trading is as follows :— Gross profit, £44,756 7s. 3d.; deduct interest and deprecia- tion, £13,039 2s. 9d.; net profit for year, £31,717 4s. 6d.; add balance brought forward, £14,892 7s. Id., making £46,609 Ils. 7d.; deduct interim dividend of 2J per cent, on 275,000 ordinary shares (paid on December 28, 1914), £6,875 ; balance for disposal, £39,734 Ils. 7d. The directors recom- mend the following appropriations :—To reserve fund to meet calls on shares taken in the Firbeck Main Collieries Limited, £10,000; to pay on the 28th inst. a final dividend on 275,000 ordinary shares at 7J per cent., making 10 per cent, for the year, £20,625; to reserve for dividend on 12,500 ordinary shares (formerly deferred shares) at 10 per cent, per annum as from December 21 last, £342 9s. 4d.; to carry forward, £8,767 2si 3d. By special resolutions passed on November 30, 1914, and confirmed on December 21, the capital of the .company now consists of 287,500 ordinary shares of £1 each, and the deferred shares are entitled to rank for dividend pari passu with the ordinary shares as from December 21 last. It is proposed to pay the balance of dividend, less tax, except in the case of the 12,500 ordinary shares which, prior to the resolutions above referred to, were denominated deferred shares, dividend on this portion of the capital being subject to the decision of the umpire, whose award has not yet been received. Advanced wages represent a serious increase in the working cost. The cost of working has also increased owing to the loss of output following the enlistment in his Majesty’s Forces by March 31 last of 548 men— representing 23 per cent, of the total number employed prior to the outbreak of war—to the larger percentage of absentees amongst the men who remained, and to the higher prices of materials and stores of all kinds. The selling prices of coal, coke, and by-products declined seriously until the commence- ment of the year 1915, when it became possible to secure considerably higher prices for coal not already sold under contract. Additional cottages are being erected for the accommodation of the company’s workmen, some of whom now travel a considerable distance to their work. The leases to this company and to the Firbeck Main Collieries Limited are settled, and a Bill to construct a railway from Worksop to Bawtry, passing the site of the proposed colliery, has been approved by a Committee of the House of Commons. Ebbw Yale Steel, Iron and Coal Company Limited.—The report for the year ended March 31 states that, owing to an unfortunate stoppage of work in April, and to the outbreak of war in August, the output of the collieries is down by nearly a-quarter of a million tons. The iron and' steel departments, in consequence of the stoppage of the collieries, came to a standstill early in May, and were idle for 4J months. The electrification of No. 5 pit, Ebbw Vale, has
