the discoverer as anybody. Dr. Syx attempted no concealment, but his smile became more than usually scornful as he stopped a laden car and invited the visitors to help themselves.

"I think," he said, "that I have struck the only lode of this ore in the Teton, or possibly in this part of the world, but I don't know for certain. There may be plenty of it only waiting to be found. That, however, doesn't trouble me. The great point is that nobody except myself knows how to extract the metal."

Mr. Boon closely examined the chunk of rock which he had taken from the car. Then he pulled a lens from his pocket, with a deprecatory glance at Dr. Syx.

"Oh, that's all right," said the latter, with a laugh, the first that these gentlemen had ever heard from his lips, and it almost made them shudder; "put it to every test, examine it with the microscope, with fire, with electricity, with the spectroscope--in every way you can think of! I assure you it is worth your while!"

Again Dr. Syx uttered his freezing laugh, passing into the familiar smile, which had now become an undisguised mock.

"Upon my word," said Mr. Boon, taking his eye from the lens, "I see no sign of any metal here!"

"Look at the green specks!" cried the doctor, snatching the specimen from the president's hand. "That's it! That's artemisium! But it's of no use unless you can get it out and purify it, which is my secret!"

For the third time Dr. Syx laughed, and his merriment affected the visitors so disagreeably that they showed impatience to be gone. Immediately he changed his manner.

"Come into my office," he said, with a return to the graciousness which had characterized him ever since the party started from New York.

When they were all seated, and the doctor had handed round a box of cigars, he resumed the conversation in his most amiable manner.

"You see, gentlemen," he said, turning a piece of ore in his fingers, "artemisium is like aluminum. It can only be obtained in the metallic form by a special process. While these greenish particles, which you may perhaps mistake for chrysolite, or some similar unisilicate, really contain the precious metal, they are not entirely composed of it. The process by which I separate out the metallic element while the ore is passing through the furnace is, in truth, quite simple, and its very simplicity guards my secret. Make your minds easy as to over-production. A man is as likely to jump over the moon as to find me out."

"But," he continued, again changing his manner, "we have had business enough for one day; now for a little recreation." While speaking the doctor pressed a button on his desk, and the room, which was illuminated by electric lamps--for there were no windows in the building--suddenly became dark, except part of one wall, where a broad area of light appeared. Dr. Syx's voice had become very soothing when next he spoke: "I am fond of amusing myself with a peculiar form of the magic-lantern, which I invented some years ago, and which I have never exhibited except for the entertainment of my friends. The pictures will appear upon the wall, the apparatus being concealed."

He had hardly ceased speaking when the illuminated space seemed to melt away, leaving a great opening, through which the spectators looked as if into another world on the opposite side of the wall. For a minute or two they could not clearly discern what was presented; then, gradually, the flitting scenes and figures became more distinct until the lifelikeness of the spectacle absorbed their whole attention.

Before them passed, in panoramic review, a sunny land, filled with brilliant-hued vegetation, and dotted with villages and cities which were bright with light-colored buildings. People appeared moving through the scenes, as in a cinematograph exhibition, but with infinitely more semblance of reality. In fact, the pictures, blending
