Of course, Hall's success led to an immediate recrudescence of the efforts to extract artemisium from the Syx ore, and, equally of course, every such attempt failed. Hall, while keeping his own secret, did all he could to discourage the experiments, but they naturally believed that he must have made the very discovery which was the subject of their dreams, and he could not, without betraying himself, and upsetting the finances of the planet, directly undeceive them. The consequence was that fortunes were wasted in hopeless experimentation, and, with Hall's achievement dazzling their eyes, the deluded fortune-seekers kept on in the face of endless disappointments and disaster. And presently there came another tragedy. The Syx mill was blown up! The accident--although many people refused to regard it as an accident, and asserted that the doctor himself, in his chagrin, had applied the match--the explosion, then, occurred about sundown, and its effects were awful. The great works, with everything pertaining to them, and every rail that they contained, were blown to atoms. They disappeared as if they had never existed. Even the twin tunnels were involved in the ruin, a vast cavity being left in the mountain-side where Syx's ten acres had been. The force of the explosion was so great that the shattered rock was reduced to dust. To this fact was owing the escape of the troops camped near. While the mountain was shaken to its core, and enormous parapets of living rock were hurled down the precipices of the Teton, no missiles of appreciable size traversed the air, and not a man at the camp was injured. But Jackson's Hole, filled with red dust, looked for days afterwards like the mouth of a tremendous volcano just after an eruption. Dr. Syx had been seen entering the mill a few minutes before the catastrophe by a sentinel who was stationed about a quarter of a mile away, and who, although he was felled like an ox by the shock, and had his eyes, ears, and nostrils filled with flying dust, miraculously escaped with his life. After this a new arrangement was made whereby Andrew Hall became the sole producer of artemisium, and his wealth began to mount by leaps of millions towards the starry heights of the billions. About a year after the explosion of the Syx mill a strange rumor got about. It came first from Budapest, in Hungary, where it was averred several persons of credibility had seen Dr. Max Syx. Millions had been familiar with his face and his personal peculiarities, through actually meeting him, as well as through photographs and descriptions, and, unless there was an intention to deceive, it did not seem possible that a mistake could be made in identification. There surely never was another man who looked just like Dr. Syx. And, besides, was it not demonstrable that he must have perished in the awful destruction of his mill?
