January 16, 1914. THE COLLIERY GUARDIAN. 147 PRODUCTION OF COKE AND BRIQUETTES IN 1912 * Returns of production of coke were received from 145 colliery owners, comprising 216 separate works, 1,493 gas companies, and 18 other owners of coke ovens, comprising 18 works. The counties of Durham and York furnished 65 per cent, of the total quantity of coke made at coking ovens, and 66 per cent, of the total number of ovens were being worked in those counties. Of the 234 works (other than gasworks) where coking plant is in use, by-products were recovered in 1912 at 89. Table A. — Total quantity of coal used in the manufacture of coke.

The principal by-products were sulphate of ammonia and tar. Returns as to the manufacture of briquettes were obtained from all firms known to be engaged in the industry, South Wales being by fab the largest con- tributor in this respect. Table A shows the quantity and value of coke obtained and the amount of coal used in the manufacture thereof at gasworks and coke ovens in the United Kingdom during the year 1912. Table B shows the number and kind of coking ovens in use in the United Kingdom during the year 1912. The following shows the principal centres of the coke industry, the first figure being the quantity of coal carbonised and the figures in parentheses the quantity of coke obtained:—Durham, 7,785,920 tons (5,053,453 tons) ; Yorkshire, 5,678,905 tons (3,129,003) tons) ; Lancushire, 2,796,340 tons (1,455,530 tons) ; Essex, 1,477,527 tons (691,190 tons) ; Glamorgan, 1,316,221 tons (747,649 tons, including the coke made at coke ovens in Denbigh) ; Stafford, 1,124,201 tons (658,501 tons); Surrey, 1,113,553 tons (658,501 tons); Lanark- shire, 1,112,328 tons (553,728) tons); Kent, 1,040,613 tons (473,945 tons, not including coke made at coke ovens); Middlesex, 1,037,323 tons (482,318 tons) ; Monmouth, 1,009,637 tons (617,344 tons) ; Derby, 920,099 tons * From Part III, of the General Report on Mines and Quarries, 1912.

The formal opening of the new headquarters of the Institution of Mining and Metallurgy (No. 1, Finsbury- circus, E.O.) was performed by the Lord Mayor (Sir T. Vansittart Bowater) on Tuesday afternoon. Founded in 1892 for the advancement of the science and practice of mining and metallurgy, the institution has drawn a large membership from the ranks of mining engineers engaged in gold and silver mining and the winning of copper, tin, and other metals. The member- ship, which in 1899, seven years after its formation, numbered 585, has increased to 2,372. The annual income is now £5,000, and capital funds have accumulated to an amount of £19,025. Up to the present, the institution has had its head- quarters at Salisbury House, the meetings having been held at Burlington House. The growth of the institu- tion rendered imperative the need of more suitable accommodation, and fox’ some years a fund for the purpose of acquiring new premises has been accumu- lating. The opportunity of securing a house in the somewhat circumscribed area from which the bulk of the London members are drawn did not present itself immediately, but in being able to purchase the freehold of this fine old Georgian mansion, the council have been exceptionally fortunate. Within a stone’s throw of the busiest centre of the City, the house, with its charming aspect upon the Circus gardens, is sufficient, apart from the noise and bustle of the thoroughfares, to provide a refuge for repose or study. The interior has not been greatly altered, but in some cases partitions have been removed, and the existing floors strengthened by girders. The ground floor contains the general and secretary’s offices; handsome council and reading rooms are provided on the first floor; the second floor has been allocated to the library; and writing and smoking rooms have been set apart on. the third floor. There is also a large smoking room in the basement. The principal rooms have been entirely refurnished, the work having been executed in the most tasteful and utilitarian fashion. The free use of light-coloured materials does much to counteract the gloom that sometimes assails the city. The alterations and redecoration of the house were executed by Messrs. J. Waddington and Sons Limited, builders, of Creed-lane, E.C., under the super- vision of Mr. A. S. R. Ley, of Bishopsgate, E.O. The principal rooms were refurnished by Messrs. Brew and Fountain, cabinetmakers, of South-place, E.C. In welcoming his lordship, the President (Mr. Bedford McNeill) said the necessity for the institution was proved by what they had already accomplished. Their chief aims were to advance the science and practice of mining and metallurgy and to raise the status of theii' profession, and, from a comparatively small beginning, they had steadily risen, year by year, in numbers and importance and with increasing usefulness, and could claim to have made considerable progress towards attaining the objects which the founders started out to secure. That day was the 22nd anniversary of their foundation. It was their belief in the higher|aims of the
