MINERAL PRODUCTS. 9 of the United States,” and the 1913 volume also contains a map showing the distribution of limestone. The Bureau of Mines has issued a comprehensive report on coal analyses (Bulletin 22), representing the important analytical work done in connection with the fuel investigations by that bureau as well as the field surveys by the Geological Survey. Another bulletin on the same subject, including the analyses made since July 1, 1910, is in press and will be issued early in September. The Bureau of Foreign and Domestic Commerce of the Depart ment of Commerce issues a “ Monthly Summary of Commerce and Finance of the United States,” which is, of course, the source of authoritative data regarding imports and exports. Another source of information that is of service to the public is the Geological Survey’s list of mineral producers. In response to specific inquiries as to the location of mines of any kind tributary to any particular market, extracts can be furnished from this list. The list, however, is not published, as it includes about 90,000 names and addresses of producers and is constantly being revised, the changes each year amounting to 25 per cent of the list. It can be largely utilized, however, in reply to inquiries from consumers of mineral products. THE MINERAL PRODUCTS. VALUE AND SUPPLY. The value of the mineral production of the United States now reaches $2,500,000,000 a year. Though this value falls far below that of the country’s farm products, the magnitude and scope of our mineral industry may be best measured by comparing our own mineral production with that of other countries, no one of which can compete with us in abundance or variety of mineral resources. The United States mines nearly 40 per cent of the world’s output of coal and produced 65 per cent of the petroleum in 1913. Of the more essential metals, 40 per cent of the world’s output of iron ore is raised from American mines, and the smelters of the United States furnish the world with 55 per cent of its copper and at least 30 per cent of its lead and zinc. These are the raw materials on which has been founded a great metallurgical industry, but on which can be built much more extensive chemical and metal-working industries. The table of production published each year by the Geological Survey contains no less than 12 items. For present purposes only a relatively small number of these items need to be mentioned, and for convenience these may be grouped under three general head ings—mineral fuels, metals, and miscellaneous minerals, the last heading including principally structural materials, fertilizers, and crude chemicals. In each of these groups there are several minerals which already enter largely into the world’s commerce, and their
