Both metals possess in common, and neither in any different degree from the other, all the qualities which are recognized as necessary in a commodity money. Silver enjoys in an equal degree with gold the quality of indestructibility, of divisibility, of malleability, and of resistance to chemical changes. The stock of both existing in the world (the product of all time) is estimated to be about equal, the production of the past 500 years being set down as-- Gold $7,240,000,000 Silver 7,435,000,000 That silver mining has not proved exceptionally profitable in this country is proved by the comparatively small number that have engaged in the business. This country has been thoroughly explored in the search for additional mines without any of great value being discovered. The allurements of the business lie in its uncertainty; and for the occasional prize that is drawn thousands of blanks are found. There is always enough hope of results to induce continued effort, but there is also sufficient doubt and discouragement to deter an undue number from engaging in the business. The mines of Mexico have been worked for hundreds of years; and up to 1873 the business of silver mining in that country had all the stimulus that a parity at 15-1/2 to 1 could give to it. It is not, therefore, probable that any material increase of output can be expected from that quarter. Conceding, for the sake of the argument, the eventual possibility of so superabundant a yield of silver as to work injury and inequity to the interests of creditors, is it not manifest that it is in the power of society at all times to remedy the evil by a limitation of the coinage? And on the other hand, is it not equally manifest that for an insufficient supply there is no remedy? If great mountains of silver should be discovered, does not Congress meet constantly? If there should seem to be too much, could not the coinage be readily limited to prevent depreciation? But, on the other hand, when we dedicate the monetary function solely to one metal, of which there is manifestly and admittedly the world over an insufficient supply, where is the remedy? What can Congress do to enlarge that supply? Absolutely nothing. THE GOLD USED IN THE ARTS. The Director of the United States Mint a few years ago estimated that of the $100,000,000 gold annually produced from the mines of the world $46,000,000 are consumed in the manufacture of jewelry, gold plate, plated ware, gold-leaf, etc., and in various processes of dentistry. The single standard of gold, therefore, is maintained by the creditor nations in the face of the admitted fact that but $50,000,000 of that metal are annually added to the money stocks.
