House- hold consumption is dimininishing with the warmer weather, but the pressure to secure adequate supplies for winter stocks is increasing. All prices are stationary. The supply of tonnage still governs the position. A fair enquiry for next month’s delivery is current on the Tyne and Wear, and bunkers are moving freely. Searching for loose lots continues a feature in Lancashire. Hardly any diminution in the demand for house coal is evident in Yorkshire or the Midlands. The market in Cardiff is inclined to be irregular and weak in consequence of the moderate tonnage failing to meet requirements. Monmouth- shire coals are accumulating, and prices fluctuate ( considerably. The outlook in Scotland is dull and . featureless. Freights are higher, especially for neutral destina- tions, but no material improvement in the number of boats offered is reported. It is expected that an announcement will be made after Whitsuntide relative to the basis of agreement between the coal owners and the Controller of Coal Mines. It is understood that the. Coal Controller is pre- > paring a schedule of revised prices for export on a graded scale. . • Despite a request from the Coal Controller, the representatives of the South Wales miners state that Monday, Tuesday and Wednesday next will be taken as a holiday. s The Government has decided that more miners must be released for Army service. Subject to specified exceptions it is. proposed to recruit at first among men who entered the industry since August 4, 1914. The annual conference of the Miners’ Federation of Great Britain will be held in Glasgow early in July. By an Order dated May 9, the Home Secretary added il Stomonal No. 2” to the permitted explo- sives named and defined in the First Schedule of the Explosives in Coal Mines Order of September 1, 1913. . ‘ One of the noteworthy resolutions recently passed by the Imperial War Conference states that it is desirable to establish in London an Imperial Mineral Resources Bureau, upon which should be represented Great Britain, the Dominions, India and other parts of the Empire. This bureau should, in the opinion of the conference, be charged with the duties of collecting information from the appropriate departments of the Governments concerned, and other sources, regarding the mineral resources and the metal requirements of the Empire, and of advising from time to time what action, if any, may appear desirable to enable such resources to be developed and made available to meet the metal requirements of the Empire. The conference also recommends that his Majesty’s Government should, while having regard to existing institutions, take immediate action for the purpose of establishing such a bureau, and should as soon as possible submit a scheme for the consideration of the other Govern- ments summoned to the conference. » It is hardly likely that so explicit a recommendation will be pigeon-holed amongst the numerous pious resolutions which have been laid aside for a more convenient season, for there is no better time than the present to carry out so obviously useful a scheme. The nation has been taught a sharp lesson on the serious Jeonsequences resulting from the neglect to exercise any sort of control over our mineral resources. Their discovery and exploitation have been left largely to private enterprise; and the disclosure of recent German efforts to use British minerals to their own advantage has scandalised the nation. Although there is little fear of a reversion to our former neglect ' in regard to the control of our own minerals, it is clear that there is need of a great deal of organised effort before we can be assured that we are making the best possible use of the bountiful gifts which nature has bestowed so lavishly upon us. For it is now abundantly evident that we can at least be self- supporting so far as our useful minerals are con- cerned, with the possible exception of a few of the rarer and less essential kinds. When we come, however, to the practical question of establishing a Mineral Resources Bureau, with *• due regard to existing institutions, we are met by .the. necessity of defining more accurately what are these existing institutions which claim special con- sideration. The Imperial Institute is the first to demand attention, because it was precisely with the object of keeping in touch with the raw materials produced within the Empire that this institution was founded. Its charter provides for the performance of all the functions of a Raw Materials Bureau, but it has never yet been in a position to carry out its full programme ; while both its buildings and its sphere of action have been continually entrenched upon by other departments. It has never been allowed to develop along its legitimate lines, because its possibilities have' never been adequately or seriously realised, and the funds at its disposal have been miserably inadequate for any one of the purposes for which it was formed. The Dominions Royal Commission, in their final report,- recently published, offer some striking criticisms of the organisation I of the Imperial Institute, which clearly illustrate its shortcomings. As an exhibition of Imperial products it is neither complete nor up-to- date. . As a technical laboratory its action is practically confined to the Crown Colonies and India. The Dominions possess better equipped technical depart- ments of their own, and have little or no need of the assistance which the Imperial Institute might afford. Its official publication, the quarterly Bulletin, possesses a very limited circulation, and is largely confined to the consideration of purely organic products. The dissemination of information upon mineral products, and, indeed, of commercial matters generally, has been further curtailed by the establishment of the Commercial Intelligence Depart- ment of the Board of Trade, which has taken over a large part of the work previously done in this direction by the Imperial Institute. As late as last year, it was stated in Parliament
