After the failure of the mining operations there was a moderate revival of the efforts to reduce the Teton ore, but no success cheered the experimenters. Prospectors also wandered all over the earth looking for pure artemisium, but in vain. The general public, knowing nothing of what Hall had discovered, and still believing Syx's story that he also had found pure artemisium in his mine, accounted for the failure of the tunnelling operations on the supposition that the metal, in a free state, was excessively rare, and that Dr. Syx had had the luck to strike the only vein of it that the Grand Teton contained. As if to give countenance to this opinion, Dr. Syx now announced, in the most public manner, that he had been deceived again, and that the vein of free metal he had struck being exhausted, no other had appeared. Accordingly, he said, he must henceforth rely exclusively, as in the beginning, upon reduction of the ore. Artemisium had proved itself an immense boon to mankind, and the new era of commercial prosperity which it had ushered in already exceeded everything that the world had known in the past. School-children learned that human civilization had taken five great strides, known respectively, beginning at the bottom, as the "age of stone," the "age of bronze," the "age of iron," the "age of gold," and the "age of artemisium." Nevertheless, sources of dissatisfaction finally began to appear, and, after the nature of such things, they developed with marvellous rapidity. People began to grumble about "contraction of the currency." In every country there arose a party which demanded "free money." Demagogues pointed to the brief reign of paper money after the demonetization of gold as a happy period, when the people had enjoyed their rights, and the "money barons"--borrowing a term from nineteenth-century history--were kept at bay. Then came denunciations of the international commission for restricting the coinage. Dr. Syx was described as "a devil-fish sucking the veins of the planet and holding it helpless in the grasp of his tentacular billions." In the United States meetings of agitators passed furious resolutions, denouncing the government, assailing the rich, cursing Dr. Syx, and calling upon "the oppressed" to rise and "take their own." The final outcome was, of course, violence. Mobs had to be suppressed by military force. But the most dramatic scene in the tragedy occurred at the Grand Teton. Excited by inflammatory speeches and printed documents, several thousand armed men assembled in the neighborhood of Jenny's Lake and prepared to attack the Syx mine. For some reason the military guard had been depleted, and the mob, under the leadership of a man named Bings, who showed no little talent as a commander and strategist, surprised the small force of soldiers and locked them up in their own guard-house.
