"Professor Vanlief," she curtsied.
They were walking, by now, in the shade of the afternoon sun. Vane saw a stage approaching them, one that would take him back to the lower town. She saw it, too, and his intention. She shook hands with him, and took time to say, softly:
"Do you never ride in the Park any more?"
"Oh," he said, "tell me when. To-morrow morning? At McGowan's Pass? At ten? Oh, how I wish that stage was not coming so fast!"
In their confusion, and their joyous sense of having the same absurd thought in common, they both laughed at the notion of a Fifth avenue stage ever being too fast. Yet this one, and Time, sped so swiftly that Vane could only shake hands hastily with his fair companion, look at her worshipfully, and jump upon the clattering vehicle.
He would never have believed that so ramshackle a conveyance could have harbored so many dreams as had been his that day.
That thought was his companion all the way home. That, and efforts to define his feelings toward Miss Vanlief. Was it love? What else could it be! And if it was, was he ready, for her, to give up those ambitions of still further sounding hitherto unexplored avenues of the human mind? Was this fragile bit of grace and glamour to come between him and the chance of opening a new field to science? Had he not the opportunity to become famous, or, at the very least, to become omnipotent in reading the hearts, the souls, of men? Were not the possibilities of the Professor's discovery unlimited? Was it not easy by means of that mirror in his rooms, for any chief of police in the world to read the guilt or innocence of every accused man? Yet, on the other hand, would marriage interfere? Yes; it would. One could not serve two such goddesses as woman and science. He would have to make up his mind, to decide.
But, in the meanwhile, there was plenty of time. Surely, for the present, he could be happy in the thought of the morrow, of the ride they were to take in the Park, of the cantering, the chattering together, the chance to see the morning wind spin the twists of gold about her cheeks and bring the sparkle to her eyes.
He let himself into his house without disturbing any of the servants. He passed into his room. He lifted the curtain of the doorway with one hand, and with the other turned the button that lighted the room. As the globes filled with light they showed him his image in the new mirror.
He reeled against the wall with the surprise of the thing. He noted the mirror's curtain in a heap at the foot of the frame. Perhaps, after all, it had been merely the wind.
