But in another instant the commotion was over, and the world whose curious spectacles had been enacted as if on the other side of a window, seemed to retreat swiftly into space, until at last, emerging from a fleecy cloud, it reappeared in the form of the full moon hanging in the sky, but larger than is its wont, with its dry ocean-beds, its keen-spired peaks, its ragged mountain ranges, its gaping chasms, its immense crater rings, and Tycho, the chief of them all, shooting raylike streaks across the scarred face of the abandoned lunar globe. The show was ended, and Dr. Syx, turning on only a partial illumination in the room, rose slowly to his feet, his tall form appearing strangely magnified in the gloom, and invited his bewildered guests to accompany him to his house, outside the mill, where he said dinner awaited them. As they emerged into daylight they acted like persons just aroused from an opiate dream. V WONDERS OF THE NEW METAL Within a twelvemonth after the visit of President Boon and his fellow financiers to the mine in the Grand Teton a railway had been constructed from Jackson's Hole, connecting with one of the Pacific lines, and the distribution of the new metal was begun. All of Dr. Syx's terms had been accepted. United States troops occupied a permanent encampment on the upper waters of the Snake River, to afford protection, and as the consignments of precious ingots were hurried east and west on guarded trains, the mints all over the world resumed their activity. Once more a common monetary standard prevailed, and commerce revived as if touched by a magic wand. Artemisium quickly won its way in popular favor. Its matchless beauty alone was enough. Not only was it gladly accepted in the form of money, but its success was instantaneous in the arts. Dr. Syx and the inspectors representing the various nations found it difficult to limit the output to the agreed upon amount. The demand was incessant. Goldsmiths and jewellers continually discovered new excellences in the wonderful metal. Its properties of translucence and refraction enabled skilful artists to perform marvels. By suitable management a chain of artemisium could be made to resemble a string of vari-colored gems, each separate link having a tint of its own, while, as the wearer moved, delicate complementary colors chased one another, in rapid undulation, from end to end.
