was and what she was doing in the big, lonely house. He wished she could have been in the room to hear his answers and approve them. He felt incomplete without her. Already he thought of her as the melody to which he was the accompaniment, two things that ought not to be separated.
"My point is," Mr. Skale continued, "that, apart from ordinary human ties, and so forth, you have no intrinsic terror of death—of losing your present body?"
"No, no," was the reply, more faintly given than the rest. "I love my life, but—but—" he looked about him in some confusion for the right words, still thinking of Miriam—"but I look forward, Mr. Skale; I look forward." He dropped back into the depths of his armchair and puffed swiftly at the end of his extinguished cigarette, oblivious of the fact that no smoke came.
"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.
"So far, so good," he said, "and now, with your permission, Mr. Spinrobin, I should like to go a step further. I should like to take—your note."
"My note?" exclaimed the other, thinking he had not heard correctly.
"Your sound, yes," repeated the clergyman.
"My sound!" piped the little man, vastly puzzled, his voice shrill with excitement. He dodged about in the depths of his big leather chair, as though movement might bring explanation.
Mr. Skale watched him calmly. "I want to get the vibrations of your voice, and then see what pattern they produce in the sand," he said.
"Oh, in the sand, yes; quite so," replied the secretary. He remembered how the vibrations of an elastic membrane can throw dry sand, loosely scattered upon its surface, into various floral and geometrical figures. Chladni's figures, he seemed to remember, they were called after their discoverer. But Mr. Skale's purpose in the main, of course, escaped him.
"You don't object?"
"On the contrary, I am greatly interested." He stood up on the mat beside his employer.
"I wish to make quite sure," the clergyman added gravely, "that your voice, your note, is what I think it is—accurately in harmony with mine and Miriam's and Mrs. Mawle's. The pattern it makes will help to prove this."
The secretary bowed in perplexed silence, while Mr. Skale crossed the room and took a violin from its case. The golden varnish of its ribs and back gleamed in the lamplight, and when the clergyman drew the bow across the strings to tune it, smooth, mellow sounds, soft and resonant as bells, filled the room. Evidently he knew how to handle the instrument. The notes died away in a murmur.
"A Guarnerius," he explained, "and a perfect pedigree specimen; it has the most sensitive structure imaginable, and carries vibrations almost like a human nerve. For instance, while I speak," he added, laying the violin upon his companion's hand, "you will feel the vibrations of my voice run through the wood into your palm."
"I do," said Spinrobin. It trembled like a living thing.
"Now," continued Mr. Skale, after a pause, "what I first want is to receive the vibrations of your own voice in the same way—into my very pulses. Kindly read aloud steadily while I hold it. Stop reading when I make a sign. I'll nod, so that the vibrations of my voice won't interfere." And he handed a notebook to him with quotations entered neatly in his own handwriting, selected evidently with a purpose, and all dealing with sound, music, as organized sound, and names. Spinrobin read aloud; the first quotation from Meredith he recognized, but the others, and the last one, discussing names, were new to him:—
"But listen in the thought; so may there come Conception of a newly-added chord, Commanding space beyond where ear has home.
"Everything that the sun shines upon sings or can be made to sing, and can be heard to sing. Gases, impalpable powders, and woolen stuffs, in common with other non-conductors of sound, give forth notes of different pitches when played upon by an intermittent beam of white light. Colored stuffs will sing in lights of different colors, but refuse to sing in others. The polarization of light being now accomplished, light and sound are known to be alike. Flames have a modulated voice and can be made to sing a definite melody. Wood, stone, metal, skins, fibers, membranes, every rapidly vibrating substance, all have in them the potentialities of musical sound.
