The critical monetary and financial situation during Cleveland's second administration is understandable only in the light of a series of acts which were passed between 1878 and 1893. It will be remembered that in the former year the Bland-Allison act had provided for the purchase and coinage of two million to four million dollars' worth of silver bullion per month, and that the force behind the measure had been found chiefly among westerners who wished to see the volume of the currency increased and among mine owners who were producing silver. The passage of the law did not end all opposition to the greater use of silver, nor did it solve all our monetary difficulties. In the first place, the United States sent delegates to an International Monetary Conference in Paris, in conformity with one of the provisions of the Bland-Allison act, to discuss a project for the utilization of silver through an agreement among the commercial nations of the world. No tangible results were obtained, however, so that it was plain that for the time, at least, the United States would be alone in its attempt to bring about the greater use of the white metal. In the meantime the law was put into operation, and the secretary of the treasury exercised his option by purchasing the minimum amount, two million dollars' worth of bullion. It was impossible to keep the coins in circulation, however, mainly because of their weight, and the policy was therefore adopted of storing part of the silver in the government vaults and issuing paper "silver certificates" in its place. As these were of small denominations and circulated on a par with gold, no immediate difficulty was experienced in making them part of the currency supply of the country.
