Is this not riddling the secret of existence? To reach the innermost depths of another's spirit; to put on his soul, as others can put on your clothes, if you left them on a chair,--is this not a stupendous thing?" In his fever and fervor the professor had exhausted his strength; he flung himself into a chair. Vane saw the old man's eyes glowing and his chest throbbing with passion; he hardly knew whether the whole scene was real or a something imposed upon his senses by a species of hypnotism. He passed his hand before his forehead; he shook his head. Yet nothing changed. Vanlief, in the chair, still quaking with excitement; the mirror, veiled and immobile. For a time the room stood silent, save for Vanlief's heavy breathing. "Of course," he resumed presently, in a quieter tone, "you cannot be expected to believe, until you have tried. But trial is the easiest thing in the world. I can teach you the mere externals to be observed in five minutes. One trial will convince you. After that,--my dear Vane, you have the gamut of humanity to go. You can be another man every day. No secret of any human heart will be a secret to you. All wisdom can be gained by you; all knowledge, all thought, can be yours. Oh, Orson Vane, I wonder if you realize your fortune! Or--is it possible that you withdraw?" Vane got up resolutely. "No," he said, "I have faith--at last. I am with you, heart and soul. Life seems splendid to me, for the first time. When can I have the mirror taken to my house?" CHAPTER IV. Vane's dressing-room was a tasteful chamber, cool and light. Its walls, its furniture, and its hangings told of a wide range of interest. There was nowhere any obvious bias; the æsthetic was no more insistent than the sporting. Orson Vane loved red-haired women as Henner painted them, and he played the aristocratic waltzes of Chopin; but he also valued the cruel breaking-bit that he had brought home from Texas, and read the racing-column in the newspaper quite as carefully as he did the doings of his society. Some hint of this diversity of tastes showed in this, the most intimate room of his early mornings. There were some of those ruddy British prints that are now almost depressingly conventional with men of sporting habits; signed photographs of more or less prominent and personable personages were scattered pell-mell. All the chairs and lounges were of wicker; so much so that some of the men who hobnobbed with Vane declared that a visit to his dressing-room was as good as a yachting cruise. The morning was no longer young. On the avenue the advance guard of the fashionable assault upon the shopping district was already astir. The languorous heat that reflects from the town's asphalt was gaining in power momentarily.
