would have shown the silver product of that year, as will be seen fur­ther on, to have been, in round numbers, 63,500,000 fine ounces, of the commercial value, at the average price of fine silver during the year, of $0.8750 per ounce, of $55,562,500, and the coining value of $82,101,010, instead of, at 58,000,000 fine ounces, of the commercial value of $50,750,000, and the coining value of $74,989,900.
For a number of years prior to 1892, it had been the custom of the Bureau, in these reports, to make two separate estimates of the produc­tion of silver during the year under consideration, and to give their mean as the approximate silver product of such year. One of these estimates was obtained by adding together the private refiner's output of fine metal of domestic origin, the amount of unrefined silver of domes­tic origin deposited at the mints and assay offices of the United States, and the exports of silver in copper matte and ores. The other was reached by the addition of the total deposits of silver at United States mints and assay offices classified as of domestic production, the exports of domestic bullion (except mint or assay office bars), the silver exported in copper matte and ore, the bars of domestic production furnished by private refineries to manufacturers and jewelers for industrial employ­ment, and the stock of bars of current years' product (exclusive of bars bearing the stamp of a United States mint or assay office) held by banks and private refineries at the close of the year; and deducting from the sum thus obtained the silver in foreign ores and bullion smelted and refined in the United States and classified at the mints and custom­houses as of domestic production.
This is the same method that has been adopted by the Bureau for a series of years in making the estimate of the annual production of gold in the United States. Previous to 1892 it had never been the practice of the Bureau to base its estimates of the gold or silver output of the country on the data furnished by the agents employed by the Mint Bureau to report on the production of the several States and Terri­tories, because, as remarked in the Report on the Production of Gold and Silver in the United States, 1891, p. 22—
" However conscientiously the agents selected may have performed the duties assigned them, experience has proven that the tendency to exag­geration on the part of direct producers is so great, and the sources of information in many cases so imperfect, as to preclude the possibility of accepting such reports, in all cases, as correctly exhibiting the product of the different States and Territories, or in the aggregate the product of the mines of the United States."
The Bureau's method, described above, of estimating the annual product of the precious metals in the United States has been univer­sally commended by the best statisticians of the precious metals.
In the absence of any explanation or reason for such a radical change in the method of estimating the production of silver in the United States—a method which has commended itself so strongly to the minds of the most expert statisticians of the precious metals—it
