"The attitude of a brave man," said the clergyman with approval. Then, looking straight into the secretary's blue eyes, he added with increased gravity: "And therefore it would not be immoral of me to expose you to an experiment in which the penalty of a slip would be—death? Or you would not shrink from it yourself, provided the knowledge to be obtained seemed worth while?"

"That's right, sir—Mr. Skale, I mean; that's right," came the answer after an imperceptible pause.

The result of the talk seemed to satisfy the clergyman. "You must think my questions very peculiar," he said, the sternness of his face relaxing a little, "but it was necessary to understand your exact position before proceeding further. The gravity of my undertaking demands it. However, you must not let my words alarm you." He waited a moment, reflecting deeply. "You must regard them, if you will, as a kind of test," he resumed, searching his companion's face with eagle eyes, "the beginning of a series of tests in which your attitude to Miriam and hers to you, so far as that goes, was the first."

"Oh, that's all right, Mr. Skale," was his inadequate rejoinder; for the moment the name of the girl was introduced his thoughts instantly wandered out to find her. The way the clergyman pronounced it increased its power, too, for no name he uttered sounded ordinary. There seemed a curious mingling in the resonant cavity of his great mouth of the fundamental note and the overtones.

"Yes, you have the kind of courage that is necessary," Mr. Skale was saying, half to himself, "the modesty that forgets self, and the unworldly attitude that is essential. With your help I may encompass success; and I consider myself wonderfully fortunate to have found you, wonderfully fortunate…."

"I'm glad," murmured Spinrobin, thinking that so far he had not learned anything very definite about his duties, or what it was he had to do to earn so substantial a salary. Truth to tell, he did not bother much about that part of it. He was conscious only of three main desires: to pass the unknown tests, to learn the nature of Mr. Skale's discovery, with the experiment involved, and—to be with Miriam as much as possible. The whole affair was so unusual that he had already lost the common standards of judging. He let the sliding platform take him where it would, and he flattered himself that he was not fool enough to mistake originality for insanity. The clergyman, dreamer and enthusiast though he might be, was as sane as other men, saner than most.

"I hope to lead you little by little to what I have in view," Mr. Skale went on, "so that at the end of our trial month you will have learned enough to enable you to form a decision, yet not enough to—to use my knowledge should you choose to return to the world."

It was very frank, but the secretary did not feel offended. He accepted the explanation as perfectly reasonable. In his mind he knew full well what his choice would be. This was the supreme adventure he had been so long a-seeking. No ordinary obstacle could prevent his accepting it.

II

There came a pause of some length, in which Spinrobin found nothing particular to say. The lamp gurgled; the coals fell softly into the fender. Then suddenly Mr. Skale rose and stood with his back to the grate. He gazed down upon the small figure in the chair. He towered there, a kindly giant, enthusiasm burning in his eyes like lamps. His voice was very deep, his manner more solemn than before when he spoke.
