	680	MINERAL RESOURCES, 1916—PART 1.

	The figures in this table result from cooperation of the United States Bureau of the Mint and the United .States Geological Survey and are agreed upon after conference and adjustment between the two bureaus. They are, therefore, final for both. The totals are based on bullion deposits in the United States mints and assay offices and on returns to the Bureau of the Mint from the smelting and refining companies. The distribution is adjusted by information collected oy the United States Geological Survey directly from the producing mines and tabulated for the mines reports later discussed. The data giving the total production, and in part the distribution, are obtained from records of (1) the unrefined domestic gold and silver deposited in United States mints and assay offices, (2) the domestic gold and silver in fine bars reported by private refineries and (3) the unrefined domestic gold and silver contained in ores and matte exported for reduction. The last item is of small relative importance. Increase or decrease in production of gold and siher in the United States in 1916.



	In addition to the production of gold and silver by domestic smelters and refiners from domestic sources in 1916, amounting to 4,479,056 fine ounces of gold and 74,414,802 fine ounces of silver, these plants produced 800,805 fine ounces of gold and 46,251,017 fine ounces of silver from foreign ores.
