Out of the crater there came no sound of heavy objects striking, though Sarka felt there should have, for the cubes were almost as heavy as a man.
Then his hair almost stood on end under his helmet, for under that first aircar, where he had first seen it, the initial cube was again gleaming into life!
The thing had dissolved while being hurled over the rim, and reformed in its proper place, its station as silent sentinel under the aircar!
These cubes then, were indeed sentinels--sentinels impossible to injure. Though no force had been used against Sarka and Jaska, Sarka had the feeling that they were powerless, and that here on the edge of a crater of the Moon awful forces were being mustered against them.
Mustered slowly, sluggishly, yet surely, as though the mentality which mustered them knew them helpless, and that there was no need to hurry!
As for Jaska, she merely clung to Sarka and waited--trusting him no matter what might transpire.
On a blind chance, Sarka brought out his ray director again, turned its muzzle toward that invisibly-blue column, pressed with his fingers, moving the director back and forth.
Instantly the blue column seemed to break short off, while the broken upper portion started racing outward toward the Earth. Sarka watched it, and noted that the yellowish glow on the Earth, even as he watched, was fading out--disappearing!
"If the ray will smash the blue column, Jaska," he said, "it will also destroy its source! Come! We will go look for it!"
And, holding her hand tightly, he rose to his feet and strode boldly down the inner slope of the vast crater.
CHAPTER XIV
_The Crater Gnomes_
It seemed to Sarka, as he moved down the inner slope of the crater, that the cubes were somehow making sport of him, laughing at him, though no hint of laughter or anything resembling laughter emanated from them.
But, shutting his lips grimly, holding fast to Jaska"s hand, he proceeded on, reached the lower portion of the inner slope, where it dropped off into a seeming black abyss, and dropped, keeping to a safe speed because of the fact that both he and Jaska were attired for movement in the air--though their manner of aerial transportation could scarcely be called flying.
The anti-gravitational ovoids simply rendered ineffectual the law of gravity.
Down they dropped, endlessly it seemed, while all about them, growing gradually, a bluish glow began to make itself manifest. Sarka turned and looked at the face of Jaska and noted that it--all her being--was glowing with this strange radiance.
He smiled at her, and she smiled back.
Looking down now, to what seemed still a vast depth, they could see figures moving, tiny, almost infinitesimal, about a great circular cone, out of the depths of which came that strange bluish column whose outer tip touched the Earth.
Some inner sense warned Sarka not to touch that column, or to permit Jaska to do so. They dropped down beside it, while Sarka, for no reason that he could a.s.sign, once more took his ray director in his free hand and held it in readiness. It seemed so tiny and futile--so foolish for two people, one of them a woman--to go into the very heart of an alien world, against an unknown enemy, armed with such a tiny weapon. Two people against unguessed myriads, whose very nature was an enigma, even to Sarka.
Closer now appeared the bottom of the crater, whose floor seemed to be covered with something that looked like blue sand, or rock. From this bluish substance the glow which bathed the two Earthlings seemed to emanate.
The funnel of the crater had now given away to the immensities of s.p.a.ce, in all directions, and the cold of outside was being replaced by a warmth which promised soon to be even uncomfortable.
Then, without a jar, the two landed at the bottom of the crater, side by side, close enough almost to that great cone to touch it. Out of the cone came that bluish column, to shoot up through the funnel down which the two had lightly dropped ... and the motion of the--whatever it was--was accompanied by a muted moaning sound, like that of a distant waterfall.
They paused there, in amazement, taking stock of their surroundings.
Huge tunnels, whose roofs were lost to invisibility in the bluish haze, whose extremities could only be guessed at, reached off in all directions. As far as the two could tell they were the only living souls within the crater, though both knew better.
Sarka had the feeling, and he knew Jaska shared it with him, that innumerable eyes were studying them, innumerable intellects were cataloguing them. And somehow he sensed the presence, somewhere near, of the traitor Dalis!
Then that discordant sound again, breaking so swiftly that it fell upon the eardrums of Sarka and Jaska like the crack of doom. Out of the many tunnels, from all directions, came hordes of beings which would have made the nightmares of Paracelsus--first of the scientists of Earth--pale to insignificance.
Paracelsus had written and ill.u.s.trated his nightmares. Had hinted of strange acts of flesh-grafting--as the grafting of legs on the head of man. He had spoken, and written about, ghastly operations, from which men came forth as part men, part spiders; part men, part scorpions, dogs, cats, crocodiles....
Sarka thought, as his mind went back to those ancient books of his people in which still remained vestiges of the theories of Paracelsus, that somehow, in his dreams, Paracelsus must have visited the craters of the Moon.
These people ... if they could be called people....
They had heads like the heads of Earthlings, broad-domed of brow, lacking eyelashes or lids, so that their eyes were perpetually staring. They possessed no bodies at all, and their legs, thin and attenuated to the size of the wrists of average men, seemed to support the ma.s.sive heads with difficulty!
From all directions they came, looking like spiders such as Sarka the First had described to Sarka, when Sarka had been a mere boy. They came on the floor, out of the tunnels; they dropped from the walls of the tunnels, and down from the invisible roofs, landing on the floor as lightly as feathers--and all converged on Jaska and Sarka.
They seemed to have no fear at all, but only a vast curiosity.
Closer and closer they came.
Jaska"s grip tightened on the hand of Sarka, for one of the creatures, with a spiderish leap, had jumped upon her, fastening its legs in her tight-fitting costume, where he hung, his face within an inch or two of hers. His lidless eyes, unblinking, stared deeply into hers.
Others jumped up beside the first, and still others clambered over Sarka, until both Sarka and Jaska were covered by them like beetles attacked by ants. But these strange gnomelike creatures, who did not fear these strangers, apparently meant them no harm.
Then, after a thorough scrutiny, began the strangest talking Sarka had ever heard. The crater-Gnomes seemed to communicate by making strange clucking sounds with their tongues, sounds which were unmusical and discordant, and which, as the Gnomes who stood back from them, because already the two were covered until no more could cling to Jaska or Sarka, joined in the speech--mounted in the cavern to a vast crescendo of sound.
Sarka knew then that this was the sound which had come out to them while they crouched at the crater rim. These were people of the Moon: but if these were Moon-men, what, or who, were those gleaming cubes?
"Stand perfectly still," Sarka mentally admonished Jaska, "they apparently mean us no harm!"
He had not spoken aloud, had not allowed his thought to reach any but Jaska; yet instantly the discordant clucking ceased, and the Gnomes were quiet, as though they politely listened to someone who had interrupted them, yet whose interruption they resented, or were curious about.
Wondering how the creature would regard his action, Sarka reached forth and plucked away the first Gnome which had jumped upon Jaska, and placed him gently on the ground. The thing merely stared at Sarka with his lidless eyes, as though wondering at Sarka"s meaning. Then his lips, which were triangular, rather than straight as those of Earthlings, began again that strange clucking.
Immediately the Gnomes which clung to Jaska and Sarka dropped away, and scuttled into the midst of the myriads that stood and watched.
They did not understand the speech of these Earthlings, but they were unusually clever in comprehending the meaning of gestures.
"Hold fast to me, Jaska," thought Sarka toward her--and wondered anew as the Gnomes instantly ceased their clucking sounds--"for I am going to try an experiment."
Holding her hand still, he turned and strode straight toward the huge cone out of which rose the bluish column.
Instantly the Gnomes broke into a frightful clucking of tongues, a sound that mounted to ear-drum-breaking intensity, and in a trice, climbing over one another to get into position, they moved in between Sarka and the cone. So eager were they to bar his further progress that they stood atop one another, until the depth of them was as tall as Sarka standing upright.
Yet, though they plainly said to Sarka: "You must not approach the cone," they did not seem to be angry with their visitors, but only curious. Sarka looked at Jaska, noted how wanly she smiled.
