His words were of the best English, but there was some peculiarity, which they had already noticed, either in his voice or his manner of enunciation, which struck all of the listeners as denoting a foreigner. But none of them could satisfactorily place him. Neither the Americans, the Englishmen, the Germans, the Frenchmen, the Russians, the Austrians, the Italians, the Spaniards, the Turks, the Japanese, or the Chinese at the board could decide to what race or nationality the stranger belonged. "This metal," he began, taking the card from Mr. Boon's hand, "I have discovered and named. I call it 'artemisium.' I can produce it, in the pure form, abundantly enough to replace gold, giving it the same relative value that gold possessed when it was the universal standard." As Dr. Syx spoke he snapped the card with his thumb-nail and it fluttered with quivering hues like a humming-bird hovering over a flower. He seemed to await a reply, and President Boon asked: "What guarantee can you give that the supply would be adequate and continuous?" "I will conduct a committee of this congress to my mine in the Rocky Mountains, where, in anticipation of the event, I have accumulated enough refined artemisium to provide every civilized land with an amount of coin equivalent to that which it formerly held in gold. I can there satisfy you of my ability to maintain the production." "But how do we know that this metal of yours will answer the purpose?" "Try it," was the laconic reply. "There is another difficulty," pursued the president. "People will not accept a new metal in place of gold unless they are convinced that it possesses equal intrinsic value. They must first become familiar with it, and it must be abundant enough and desirable enough to be used sparingly in the arts, just as gold was." "I have provided for all that," said the stranger, with one of his disconcerting smiles. "I assure you that there will be no trouble with the people. They will be only too eager to get and to use the metal. Let me show you." He stepped to the door and immediately returned with two black attendants bearing a large tray filled with articles shaped from the same metal as that of which the card was composed. The financiers all jumped to their feet with exclamations of surprise and admiration, and gathered around the tray, whose dazzling contents lighted up the corner of the room where it had been placed as if the moon were shining there.
