An attendant entered the room where the perplexed financiers were in session and presented a peculiar-looking card to the president, Mr. Boon. The president took the card in his hand and instantly fell into a brown study. So complete was his absorption that Herr Finster, the celebrated Berlin banker, who had been addressing the chair for the last two hours from the opposite end of the long table, got confused, entirely lost track of his verb, and suddenly dropped into his seat, very red in the face and wearing a most injured expression. But President Boon paid no attention except to the singular card, which he continued to turn over and over, balancing it on his fingers and holding it now at arm's-length and then near his nose, with one eye squinted as if he were trying to look through a hole in the card. At length this odd conduct of the presiding officer drew all eyes upon the card, and then everybody shared the interest of Mr. Boon. In shape and size the card was not extraordinary, but it was composed of metal. What metal? That question had immediately arisen in Mr. Boon's mind when the card came into his hand, and now it exercised the wits of all the others. Plainly it was not tin, brass, copper, bronze, silver, aluminum--although its lightness might have suggested that metal--nor even base gold. The president, although a skilled metallurgist, confessed his inability to say what it was. So intent had he become in examining the curious bit of metal that he forgot it was a visitor's card of introduction, and did not even look for the name which it presumably bore. As he held the card up to get a better light upon it a stray sunbeam from the window fell across the metal and instantly it bloomed with exquisite colors! The president's chair being in the darker end of the room, the radiant card suffused the atmosphere about him with a faint rose tint, playing with surprising liveliness into alternate canary color and violet. The effect upon the company of clear-headed financiers was extremely remarkable. The unknown metal appeared to exercise a kind of mesmeric influence, its soft hues blending together in a chromatic harmony which captivated the sense of vision as the ears are charmed by a perfectly rendered song. Gradually all gathered in an eager group around the president's chair. "What can it be?" was repeated from lip to lip. "Did you ever see anything like it?" asked Mr. Boon for the twentieth time. None of them had ever seen the like of it. A spell fell upon the assemblage. For five minutes no one spoke, while Mr. Boon continued to chase the flickering sunbeam with the wonderful card. Suddenly the silence was broken by a voice which had a touch of awe in it: "It must be the metal!"
