The builder was hugely impressed. He asked, eagerly: "Then probably the people became as highly developed as we?"
Van Emmon nodded approvingly, but the doctor opposed. "No; I think not, Jackson. Mercury never did have as much air as the earth, and consequently had much less oxygen. And the struggle for existence," he went on, watching to see if the geologist approved each point as he made it, "the struggle for life is, in the last a.n.a.lysis, a struggle for oxygen.
"So I would say that life was a pretty strenuous proposition here, while it lasted. Perhaps they were--" He stopped, then added: "What I can"t understand is, how did it happen that their affairs came to such an abrupt end? And why don"t we see any--er--indications?"
"Skeletons?" The architect shuddered. Next second, though, his face lit up with a thought. "I remember reading that electricity will decompose bone, in time." And then he shuddered again as his foot stirred that lifeless, impalpable dust. Was it possible?
As they pa.s.sed into the great house the first thing they noted was the floor, undivided, dust-covered, and bare, except for what had perhaps been rugs. The shape was the inevitable equilateral triangle; and here, with a certain magnificent disregard for precedent, the builders had done away with a ceiling entirely, and instead had sloped the three walls up till they met in a single point, a hundred feet overhead. The effect was ma.s.sively simple.
In one corner a section of the floor was elevated perhaps three feet above the rest, and directly back of this was a broad doorway, set in a short wall. The three advanced at once toward it.
Here the electric torch came in very handy. It disclosed a poorly lighted stairway, very broad, unrailed, and preposterously steep. The steps were each over three feet high.
"Difference in gravitation," said the doctor, in response to Jackson"s questioning look. "Easy enough for the old-timers, perhaps." They struggled up the flight as best they could, reaching the top after over five minutes of climbing.
Perhaps it was the reaction from this exertion; at all events each felt a distinct loss of confidence as, after regaining their wind, they again began to explore. Neither said anything about it to the others; but each noted a queer sense of foreboding, far more disquieting than either of them had felt when investigating anything else. It may have been due to the fact that, in their hurry, they had not stopped to eat.
The floor they were on was fairly well lighted with the usual oval windows. The s.p.a.ce was open, except that it contained the same kind of dividing walls they had found in the library. Here, however, each compartment contained but one opening, and that not uniformly placed. In fact, as the three noted with a growing uneasiness, it was necessary to pa.s.s through every one of them in order to reach the corner farthest, from the ladderlike stairs. Why it should make them uneasy, neither could have said.
When they were almost through the labyrinth, Van Emmon, after standing on tiptoes for the tenth time, in order to locate himself, noted something that had escaped their attention before. "These compartments used to be covered over," he said, for some reason lowering his voice.
He pointed out niches in the walls, such as undoubtedly once held the ends of heavy timbers. "What was this place, anyhow? A trap?"
Unconsciously they lightened their steps as they neared the last compartment. They found, as expected, that it was another stairwell. Van Emmon turned the light upon every corner of the place before going any further; but except for a formless heap of rubbish in one corner, which they did not investigate, the place was as bare as the rest of the floor.
Again they climbed, this time for a much shorter distance; but Jackson, slightly built chap that he was, needed a little help on the steep stairs. They were not sorry that they had reached the uppermost floor of the mansion. It was somewhat better lighted than the floor below, and they were relieved to find that the triangular compartments did not have the significant niches in their walls. Their spirits rose perceptibly.
At the corner farthest from the stairs one of the walls rose straight to the ceiling, completely cutting off a rather large triangle. The three paid no attention to the other compartments, but went straight to what they felt sure was the most vital spot in the place. And their feelings were justified with a vengeance when they saw that the usual doorway in this wall was protected by something that had, so far, been entirely missing everywhere else.
It was barred by a heavy door.
For several minutes the doctor, the geologist, and the architect stood before it. Neither would have liked to admit that he would just as soon leave that door unopened. All the former uneasiness came back. It was all the more inexplicable, with the brilliant sunlight only a few feet away, that each should have felt chilled by the place.
"Wonder if it"s locked?" remarked Van Emmon. He pressed against the dust-covered barrier, half expecting it to turn to dust; but evidently it had been made of the time-defying alloy. It stood firm. And to all appearances it was nearly air-tight.
"Well!" said the doctor suddenly, so that the other two started nervously. "The door"s got to come down; that"s all!" They looked around; there was no furniture, no loose piece of material of any kind.
Van Emmon straightway backed away from the door about six feet, and the others followed his example.
"All together!" grunted the geologist; and the three aluminum-armored monsters charged the door. It shook under the impact; a shower of dust fell down; and they saw that they had loosened the thing.
"Once more!" This time a wide crack showed all around the edge of the door, and the third attempt finished the job. Noiselessly--for there was no air to carry the sound--but with a heavy jar which all three felt through their feet, the barrier went flat on the floor beyond.
At the same instant a curious, invisible wave, like a tiny puff of wind, floated out of the darkness and pa.s.sed by the three men from the earth.
Each noticed it, but neither mentioned it at the time. Van Emmon was already searching the darkness with the torch.
Apparently it was only an anteroom. A few feet beyond was another wall, and in it stood another door, larger and heavier than the first. The three did not stop; they immediately tried their strength on this one also.
After a half dozen attempts without so much as shaking the ma.s.sive affair--"It"s no use," panted the geologist, wishing that he could get a handkerchief to his forehead. "We can"t loosen it without tools."
Jackson was for trying again, but the doctor agreed with Van Emmon. They reflected that they had been away from Smith long enough, anyhow. The cube was out of sight from where they were.
Van Emmon turned the light on the walls of the anteroom, and found, on a shelf at one end, a neat pile of those little reels, eleven in all. He pocketed the lot. There was nothing else.
Jackson and Kinney started to go. They retreated as far into the main room as their telephone wires would allow. Still the geologist held back.
"Come on," said the doctor uneasily. "It"s getting cold."
Next second they stopped short, nerves on edge, at a strange exclamation from Van Emmon. They looked around to see him pointing his light directly at the floor. Even in that unnatural suit of mail, his att.i.tude was one of horror.
"Look here," he said in a low, strained voice. They went to his side, and instinctively glanced behind them before looking at what lay in the dust.
It was the imprint of an enormous human foot.
The first thing that greeted the ears of the explorers upon taking off their suits in the sky-car, was the exultant voice of Smith. He was too excited to notice anything out of the way in their manner; he was almost dancing in front of his bench, where the unknown machine, now reconstructed, stood belted to a small electric-motor.
"It runs!" he was shouting. "You got here just in time!" He began to fumble with a switch.
"What of it?" remarked the doctor in the bland tone which he kept for occasions when Smith needed calming. "What will it do if it does run?"
The engineer looked blank. "Why--" Then he remembered, and picked up one of the reels at random. "There"s a clamp here just the right size to hold one of these," he explained, fitting the ribbon into place and threading its free end into a loop on a spool which looked as though made for it. But his excitement had pa.s.sed; he now cautiously set a small anvil between himself and the apparatus, and then, with the aid of a long stick, he threw on the current.
For a moment nothing happened, save the hum of the motor. Then a strange, leafy rustling sounded from the mechanism, and next, without any warning, a high-pitched voice, nasal and plaintive but distinctly human, spoke from the big metal disk.
The words were unintelligible. The language was totally unlike anything ever heard on the earth. And yet, deliberately if somewhat cringingly, the voice proceeded with what was apparently a recitation. There were modulations, pauses, sentences; but seemingly the paragraphs were all short and to the point.
As the thing went on the four men came closer and watched the operation of the machine. The ribbon unrolled slowly; it was plain that, if the one topic occupied the whole reel, then it must have the length of an ordinary chapter. And as the voice continued, certain dramatic qualities came out and governed the words, utterly incomprehensible though they were. There was a real thrill to it.
After a while they stopped the thing. "No use listening to this now," as the doctor said. "We"ve got to learn a good deal more about these people before we can guess what it all means."
And yet, although all were very hungry, on Jackson"s suggestion they tried out one of the "records" that was brought from that baffling anteroom. Smith was very much interested in that unopened door, and Van Emmon was in the midst of it when Jackson started the motor.
The geologist"s words stuck in his throat. The disk was actually shaking with the vibrations of a most terrific voice. Prodigiously loud and powerful, its booming, resonant ba.s.s smote the ears like the roll of thunder. It was irresistible in its force, compelling in its a.s.surance, masterful and strong to an overpowering degree. Involuntarily the men from the earth stepped back.
On it roared and rumbled, speaking the same language as that of the other record; but whereas the first speaker merely USED the words, the last speaker demolished them. One felt that he had extracted every ounce of power in the language, leaving it weak and flabby, unfit for further use. He threw out his sentences as though done with them; not boldly, not defiantly, least of all, tentatively, he spoke with a certainty and force that came from a knowledge that he could compel, rather than induce his hearers to believe.
It took a little nerve to shut him off; Van Emmon was the one who did it. Somehow they all felt immensely relieved when the gigantic voice was silenced; and at once began discussing the thing with great earnestness.
Jackson was for a.s.suming that the first record was worn and old, the last one, fresh and new; but after examining both tapes under a gla.s.s, and seeing how equally clear cut and sharp the impressions all were, they agreed that the extraordinary voice they had heard was practically true to life.
They tried out the rest of the records in that batch, finding that they were all by the same speaker. Nowhere among the ribbons brought from the library was another of his making, although a great number of different voices was included; neither was there another talker with a fifth the volume, the resonance, the absolute power of conviction that this unknown colossus possessed.
Of course this is no place to describe the laborious process of interpreting these doc.u.ments, records of a past which was gone before earth"s mankind had even begun. The work involved the study of countless photos, covering everything from inscriptions to parts of machinery, and other details which furnished clue after clue to that superancient language. It was not deciphered, in fact, until several years after the explorers had submitted their finds to the world"s foremost lexicographers, antiquarians and paleontologists. Even today some of it is disputed.
But right here is, most emphatically, the place to insert the tale told by that unparalleled voice. And incredible though it may seem, as judged by the standards of the peoples of this earth, the account is fairly proved by the facts uncovered by the expedition. It would be but begging the question to doubt the genuineness of the thing; and if, understanding the language, one were to hear the original as it fell, word for word from the iron mouth of Strokor [Footnote: Translator"s note--In the Mercurian language, stroke means iron, or heart.] the Great-hearing, one would believe; none could doubt, nor would.
And so it does not do him justice to set it down in ordinary print. One must imagine the story being related by Stentor himself; must conceive of each word falling like the blow of a mammoth sledge. The tale was not told--it was BELLOWED; and this is how it ran:
