He pointed at a row of what seemed to be grinning steel mouths, barred with innumerable black teeth, and half concealed by a projecting ledge at the bottom of the wall opposite the entrance, and as I looked I was thrilled by the sight of faint curls of smoke disappearing within their gaping jaws.
"They are omnivorous beasts," said Edmund. "They feed on the carbon from your breath, too. Rather remarkable, isn't it, that every time you expel the air from your lungs you help this car to go?"
None of us knew what to say; our astonishment was beyond speech. We began to look askance at Edmund, with creeping sensations about the spine. A formless, unacknowledged fear of him entered our souls. It never occurred to us to doubt the truth of what he had said. We knew him too well for that; and, then, were we not here, flying mysteriously through the air in a heavy metallic car that had no apparent motive power? For my part, instead of demanding any further explanations, I fell into a hazy reverie on the marvel of it all; and Jack and Henry must have been seized the same way, for not one of us spoke a word, or asked a question; while Edmund, satisfied, perhaps, with the impression he had made, kept equally quiet.
Thus another hour passed, and all of us, I think, had fallen into a doze, when Edmund aroused us by saying:
"I'll have to keep the first watch, and all the others, too, this night."
"So then we're not going to land to-night?"
"No, not to-night, and you may as well turn in. You see that I have prepared good, comfortable bunks, and I think you'll make out very well."
As Edmund spoke he lifted the tops from some of the benches along the walls, and revealed excellent beds, ready for occupancy.
"I believe that I have forgotten nothing that we shall really need," he added. "Beds, arms, instruments, books, clothing, furs, and good things to eat."
Again we looked at one another in surprise, but nobody spoke, although the same thought probably occurred to each—that this promised to be a pretty long trip, judging from the preparations. Arms! What in the world should we need of arms? Was he going to the Rocky Mountains for a bear hunt? And clothing, and furs!
But we were really sleepy, and none of us was very long in taking Edmund at his word and leaving him to watch alone. He considerately drew a shade over the light, and then noiselessly opened a shutter and looked out. When I saw that, I was strongly tempted to rise and take a look myself, but instead I fell asleep. My dreams were disturbed by visions of the grinning nondescripts at the foot of the wall, which transformed themselves into winged dragons, and remorselessly pursued me through the measureless abysses of space.
When I woke, windows were open on both sides of the car, and brilliant sunshine was streaming in through one of them. Henry was still asleep, Jack was yawning in his bunk, and Edmund stood at one of the windows staring out. I made a quick toilet, and hastened to Edmund's side.
"Good morning," he said heartily, taking my hand. "Look out here, and tell me what you think of the prospect."
As I put my face close to the thick but very transparent glass covering the window, my heart jumped into my mouth!
"In Heaven's name, where are we?" I cried out.
Jack, hearing my agitated exclamation, jumped out of his bunk and ran to the window also. He gasped as he gazed out, and truly it was enough to take away one's breath!
We appeared to be at an infinite elevation, and the sky, as black as ink, was ablaze with stars, although the bright sunlight was streaming into the opposite window behind us. I could see nothing of the earth. Evidently we were too high for that.
"It must lie away down under our feet," I murmured half aloud, "so that even the horizon has sunk out of sight. Heavens, what a height!"
I had that queer uncontrollable qualm that comes to every one who finds himself suddenly on the edge of a soundless deep.
Presently I became aware that straight before us, but afar off, was a most singular appearance in the sky. At first glance I thought that it was a cloud, round and mottled, But it was strangely changeless in form, and it had an unvaporous look.
"Phew!" whistled Jack, suddenly catching sight of it and fixing his eyes in a stare, "what's that?"
"That's the earth!"
It was Edmund who spoke, looking at us with a quizzical smile. A shock ran through my nerves, and for an instant my brain whirled. I saw that it was the truth that he had uttered, for, as sure as I sit here, his words had hardly struck my ears when the great cloud rounded out and hardened, the deception vanished, and I recognized, as clearly as ever I saw them on a school globe, the outlines of Asia and the Pacific Ocean!
In a second I had become too weak to stand, and I sank trembling upon a bench. But Jack, whose eyes had not accommodated themselves as rapidly as mine to the gigantic perspective, remained at the window, exclaiming:
"Fiddlesticks! What are you trying to give us? The earth is down below, I reckon."
But in another minute he, too, saw it as it really was, and his astonishment equaled mine. In fact he made so much noise about it that he awoke Henry, who, jumping out of bed, came running to see, and when we had explained to him where we were, sank upon a seat with a despairing groan and covered his face. Our astonishment and dismay were too great to permit us quickly to recover our self-command, but after a while Jack seized Edmund's arm, and demanded:
"For God's sake, tell us what you've been doing."
"Nothing that ought to appear very extraordinary," answered Edmund, with uncommon warmth. "If men had not been fools for so many ages they might have done this, and more than this long ago. It's enough to make one ashamed of his race! For countless centuries, instead of grasping the power that nature had placed at the disposal of their intelligence, they have idled away their time gabbling about nothing. And even since, at last, they have begun to do something, look at the time that they have wasted upon such petty forces as steam and 'electricity,' burning whole mines of coal and whole lakes of oil, and childishly calling upon winds and tides and waterfalls to help them, when they had under their thumbs the limitless energy of the atoms, and no more understood it than a baby understands what makes its whistle scream! It's inter-atomic force that has brought us out here, and that is going to carry us a great deal farther."
We simply listened in silence; for what could we say? The facts were more eloquent than any words, and called for no commentary. Here we were, out in the middle of space; and there was the earth, hanging on nothing, like a summer cloud. At least we knew where we were if we didn't quite understand how we had got there.
Seeing us speechless, Edmund resumed in a different tone:
"We made a fairly good run during the night. You must be hungry by this time, for you've slept late; suppose we have breakfast."
So saying, he opened a locker, took out a folding table, covered it with a white cloth, turned on something resembling a little electric range, and in a few minutes had ready as appetizing a breakfast of eggs and as good a cup of coffee as I ever tasted. It is one of the compensations of human nature that it is able to adjust itself to the most unheard-of conditions provided only that the inner man is not neglected. The smell of breakfast would almost reconcile a man to purgatory—anyhow it reconciled us for the time being to our unparalleled situation, and we ate and drank, and indulged in as cheerful good comradeship as that of a fishing party in the wilderness after a big morning's catch.
When the breakfast was finished we began to chat and smoke, which reminded me of those gulping mouths under the wainscot, and I leaned down to catch a glimpse of their rows of black fangs, thinking to ask Edmund for further explanation about them; but the sight gave me a shiver, and I felt the hopelessness of trying to understand their function.
Then we took a turn at looking out of the window to see the earth. Edmund furnished us with binoculars which enabled us to recognize many geographical features of our planet. The western shore of the Pacific was now in
