"Easily. I first ascertained that before the Antarctic discoveries the world contained altogether about 16,000 tons of gold, valued at $450,000 per ton, or $7,200,000,000 worth all told. Now my metal weighs, bulk for bulk, one-quarter as much as gold. It might be reckoned at the same intrinsic value per ton, but I have considered it preferable to take advantage of the smaller weight of the new metal, which permits us to make coins of the same size as the old ones, but only one-quarter as heavy, by giving to artemisium four times the value per ton that gold had. Thus only 4000 tons of the new metal are required to supply the place of the 16,000 tons of gold. The 2500 tons which I already have on hand are more than enough for coinage. The rest I can supply as fast as needed." The party did not wait for further explanations. They were eager to see the wonderful mine and the store of treasure. Spurs were applied, and they galloped down the steep trail, forded the Snake River, and, skirting the shore of Jenny's Lake, soon found themselves gazing up the headlong slopes and dizzy parapets of the Grand Teton. Dr. Syx led them by a steep ascent to the mouth of the canyon, above one of whose walls stood his mill, and where the "Champ! Champ!" of a powerful engine saluted their ears. IV THE WEALTH OF THE WORLD An electric light shot its penetrating rays into a gallery cut through virgin rock and running straight towards the heart of the Teton. The centre of the gallery was occupied by a narrow railway, on which a few flat cars, propelled by electric power, passed to and fro. Black-skinned and silent workmen rode on the cars, both when they came laden with broken masses of rock from the farther end of the tunnel and when they returned empty. Suddenly, to an eye situated a little way within the gallery, appeared at the entrance the dark face of Dr. Syx, wearing its most discomposing smile, and a moment later the broader countenance of President Boon loomed in the electric glare beside the doctor's black framework of eyebrows and mustache. Behind them were grouped the other visiting financiers. "This tunnel," said Dr. Syx, "leads to the mine head, where the ore-bearing rock is blasted." As he spoke a hollow roar issued from the depths of the mountain, followed in a short time by a gust of foul air. "You probably will not care to go in there," said the doctor, "and, in fact, it is very uncomfortable. But we shall follow the next car-load to the smelter, and you can witness the reduction of the ore." Accordingly when another car came rumbling out of the tunnel, with its load of cracked rock, they all accompanied it into an adjoining apartment, where it was cast into a metallic shute, through which, they were informed, it reached the furnace.
