Summary:
THE record of the annual mineral production of the United States has now increased in size until it occupies two large volumes of 2242 pages in all. These form a storehouse of information concerning a number of matters connected directly or indirectly with the mineral industry of America, whilst statistics of, and information about, the production of minerals in other parts of the world are given for the purpose of comparison. The methods are the same as those employed in previous years, one of the two volumes, being devoted to the metalliferous minerals and the other to the non-metals. From the economic point of view the latter are the more important, the value of the coal production of the United States being nearly one-third of the total value of the whole of the mineral products, this latter amounting to the huge sum of close upon 400,000,000
