window placed well up near the ceiling, his forehead contracted into a hundred wrinkles, his cheeks became feverous, his piercing eyes glowed with inner fire, and drops of perspiration ran down in front of his ears. One would have thought that he was laboring to save his very soul and had but a few seconds of respite left.
Presently he threw down the pencil, and with astonishing agility let himself rapidly, but carefully, off the stool on which he had been sitting, keeping the palms of his hands on the seat beside his hips until he felt his feet touch the floor. Then he darted at a book-shelf, pulled down a ponderous tome, flapped it open in a clear space on the floor, and dropped on his knees to consult it.
After turning a leaf or two he found what he was after, read down the page, keeping a finger on the lines, and, having finished his reading, jumped to his feet and hurried back to the stool, on which he mounted so quickly that it was impossible to see how he managed it—without an upset. Instantly he made a new diagram, and then fell to figuring furiously on the pad, making his pencil gyrate so fast that its upper end vibrated like the wing of a dragon-fly.
At last he threw down the pencil, and, encircling his knees with his clasped arms, sank in a heap on the stool. The lids dropped over his shining eyes, and he became buried in thought.
When he reopened his eyes and unbent his brows, his gaze happened to be directed toward a row of curious big photographs which ran like a pictured frieze round the upper side of the wall of the room. A casual observer might have thought that the little man had been amusing himself by photographing the explosions of fireworks on a Fourth of July night; but it was evident by his expression that these singular pictures had no connection with civic pyrotechnics, but must represent something of incomparably greater importance, and, in fact, of stupendous import.
The little man's face took on a rapt look, in which wonder and fear seemed to be blended. With a sweep of his hand he included the whole series of photographs in a comprehensive glance, and then, settling his gaze upon a particularly bizarre object in the center, he began to speak aloud, although there was nobody to listen to him.
"My God!" he said. "That's it! That Lick photograph of the Lord Rosse Nebula is its very image, except that there's no electric fire in it. The same great whirl of outer spirals, and then comes the awful central mass—and we're going to plunge straight into it. Then quintillions of tons of water will condense on the earth and cover it like a universal cloudburst. And then good-by to the human race—unless—unless—I, Cosmo Versál, inspired by science, can save a remnant to repeople the planet after the catastrophe."
Again, for a moment, he closed his eyes, and puckered his hemispherical brow, while, with drawn-up knees, he seemed perilously balanced on the high stool. Several times he slowly shook his head, like a dreaming owl, and when his eyes reopened their fire was gone, and a reflective film covered them. He began to speak, more deliberately than before, and in a musing tone:
"What can I do? I don't believe there is a mountain on the face of the globe lofty enough to lift its head above that flood. Hum, hum! It's no use thinking about mountains! The flood will be six miles deep—six miles from the present sea-level; my last calculation proves it beyond all question. And that's only a minimum—it may be miles deeper, for no mortal man can tell exactly what'll happen when the earth plunges into a nebula.
"We'll have to float; that's the thing. I'll have to build an ark. I'll be a second Noah. But I'll advise the whole world to build arks.
"Millions might save themselves that way, for the flood is not going to last forever. We'll get through the nebula in a few months, and then the waters will gradually recede, and the high lands will emerge again. It'll be an awful long time, though; I doubt if the earth will ever be just as it was before. There won't be much room, except for fish—but there won't be many inhabitants for what dry land there is."
Once more he fell into silent meditation, and while he mused there came a knock at the door. The little man started up on his seat, alert as a squirrel, and turned his eyes over his shoulder, listening intently. The knock was repeated—three quick sharp raps. Evidently he at once recognized them.
"All right," he called out, and, letting himself down, ran swiftly to the door and opened it.
A tall, thin man, with bushy black hair, heavy eyebrows, a high, narrow forehead, and a wide, clean shaven mouth, wearing a solemn kind of smile, entered and grasped the little man by both hands.
"Cosmo," he said, without wasting any time on preliminaries, "have you worked it out?"
"I have just finished."
"And you find the worst?"
"Yes, worse than I ever dreamed it would be. The waters will be six miles deep."
"Phew!" exclaimed the other, his smile fading. "That is indeed serious.
And when does it begin?"
"Inside of a year. We're within three hundred million miles of the watery nebula now, and you know that the earth travels more than that distance in twelve months."
"Have you seen it?"
"How could I see it—haven't I told you it is invisible? If it could be seen all these stupid astronomers would have spotted it long ago. But I'll tell you what I have seen."
Cosmo Versál's voice sank into a whisper, and he shuddered slightly as he went on:
"Only last night I was sweeping the sky with the telescope when I noticed, in Hercules and Lyra, and all that part of the heavens, a dimming of some of the fainter stars. It was like the shadow of the shroud of a ghost. Nobody else would have noticed it, and I wouldn't if I had not been looking for it. It's knowledge that clarifies the eyes and breeds knowledge, Joseph Smith. It was not truly visible, and yet I could see that it was there. I tried to make out the shape of the thing—but it was too indefinite. But I know very well what it is. See here"—he suddenly broke off—"Look at that photograph." (He was pointing at the Lord Rosse Nebula on the wall). "It's like that, only it's coming edgewise toward us. We may miss some of the outer spirals, but we're going smash into the center."
With fallen jaw, and black brows contracted, Joseph Smith stared at the photograph.
"It doesn't shine like that," he said at last.
The little man snorted contemptuously.
"What have I told you about its invisibility?" he demanded.
"But how, then, do you know that it is of a watery nature?"
Cosmo Versál threw up his hands and waved them in an agony of impatience. He climbed upon his stool to get nearer the level of the other's eyes, and fixing him with his gaze, exclaimed:
"You know very well how I know it. I know it because I have demonstrated with my new spectroscope, which analyzes extra-visual rays, that all those dark nebulae that were photographed in the Milky Way years ago are composed of watery vapor. They are far off, on the limits of the universe. This one is one right at hand. It's a little one compared with them—but it's enough, yes, it's enough! You know that more than two years ago I began to correspond with astronomers all over the world about this thing, and not one of them would listen to me. Well, they'll listen when it's too late perhaps.
"They'll listen when the flood-gates are opened and the inundation begins. It's not the first time that this thing has happened. I haven't a doubt that the flood of Noah, that everybody pretends to laugh at now, was caused by the earth passing through a watery
