	The figures in this table are also those of the Director of the Mint. They result from cooperation of the 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 of this table 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 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, matte, etc., exported for reduction. The last item is of small relative importance. Gains and losses in the production of gold and silver in the several States and Territories, as compared with the output of 1909, are shown in the following table: Increase (-)-) or decrease ( —) in production of precious metals in the United Slates in 1910, by States and Territories, in fine ounces.
