Because it was an untried situation, he acted at once. At this moment, he had her; there were too many unknowns for him to risk any delay. He knelt beside her. Since she was unconscious and not asleep, her sensory system was open to exterior stimulation. But for her to answer, she would have to be switched to sleep, so that the shut-off interior percep-tion could flow.
So he sat there, alternately manipulating her uncon-sciousness center, when he wanted to ask a question, and her sleep center, for her reply. It was like ancient ham radio with each party saying "over" when his message was completed.
And of course, in addition, he had to make sure that she did reply to his queries. So he asked one question after an-other, and with each question he modified a magnetic wave with a message to the brain-cell gestalt that responded to hypnotic drugs. The result was a steady mental conversation.
"What is your name?"
"B-Roth."
"Where do you come from?"
"From home."
"Where is home?"
"In the sky." A mental image came of a small stone body in s.p.a.ce; Cemp"s impression was of a meteorite less than twenty miles in diameter. "About to go around the sun, inside the first planet"s...o...b..t."
So shehad come to Earth in advance. So theywere all far from "home" and had apparently had no preliminary know-ledge that they were outskilled by Earth Silkies. As a result, he was now obtaining this decisive information.
"What is its...o...b..t?" Cemp asked.
"It goes as far out as the eighth planet."
Neptune! What a tremendous distance-nearly thirty astronomical units.
Cemp asked quickly, "What is its mean speed?"
Her answer was in terms of Mercury"s year. Converted to Earth time, it came to a hundred and ten years per orbit.
Cemp whistled softly. An immediate a.s.sociation had leaped into his mind. The first Silkie baby had been born to Marie Ederle slightly more than two hundred and twenty years before, according to the official history. The time involved was approximately twice as long as the orbital period of the little Silkie planetoid.
Cemp ended that train of speculation abruptly and demanded from B-Roth exactly how she would again find the planetoid, which surely must be one of thousands of similar bodies.
The answer was one that only a Silkie could operate from. She had in her brain a set of relationships and signal-recognition images that identified for her the location of the Silkie home.
Cemp made an exact mental copy of these images. He was about to begin questioning her for details on other matters-when an inertia phenomenon effected his body.
He was flung backward. ... It was as if he were in a vehicle, his back to the forward motion, and the vehicle stopped suddenly, but he went on.
Because he always had protection against sudden falls, he had been moved less than eight feet before he triggered his magnetic field, his only screening mechanism as a human.
The field he set up could not stop the pull of gravity directly, but it derived from the Earth"s magnetic force and gained its power from the force lines that pa.s.sed through this exact s.p.a.ce.
As Cemp modulated the lines now, they attached them-selves to flexible metal bands that were woven into his clothes, and they held him. He hung there a few feet above the floor. From this vantage point he was able to examine his situation.
At once, the phenomenon was shown as completely fantastic. He detected in the heart of the gravity field a tiny molecule complex. What was fantastic about it was this: Gravity was an invariable, solely dependent on ma.s.s and square of distance. Cemp had already calculated the gravity pull on him to be the equivalent of three times that of Earth at sea level. And so, by all the laws of physics, that incredibly small particle must have an equivalent ma.s.s to three Earths!
Impossible, of course.
It was by no means a complex of one of the large mole-cules, as far as Cemp could determine, and it was not radio-active.
He was about to abandon his study of it and to turn his attention to his own situation, when he noticed that the gravity field had an even more improbable quality. Its pull was limited to organic matter. It had no effect on the sur-rounding dirt walls, and in fact-his mind poised in a final amazement-the woman"s body was not influenced by it.
The gravity was limited to one particular organic con-figuration-himself! One body, one human being only-Nat Cemp-was the sole object toward which it was oriented.
He found himself remembering how he had been un-touched by the field that had lifted U-Brem. He had sensed the presence of a field but only by the way the magnetic lines that pa.s.sed through his head were affected by it. Even in his Silkie form, as he pursued the hurtling body of his alter ego, that, and merely that, had been true.
This was for him a personal gravitational field, a small group of molecules that "knew" him.
As these flashing awarenesses came to him, Cemp turned his head and gazed back at the young woman.
He was not surprised at what he saw. His attention had been forcibly removed from her, so the pressure on the unconsciousness valve in her brain was released. She was stirring, coming to.
She sat up, looked around, and saw him.
She came to her feet quickly, with an athletic ease. She evidently did not remember what had happened while she was unconscious, did not realize how completely she had given away basic secrets, for her face broke into a smile.
"You see?" she said. "I told you what would happen. Well, goodbye."
Her spirits visibly high, she turned, walked off into the cave, and presently disappeared as it gradually curved off to the left.
After she was gone, Cemp turned his attention back to the gravity field. He a.s.sumed that it would eventually be with-drawn or fade out, and he would be free. He had the distinct conviction that he might have only minutes in which to examine it and discover its nature.
He thought unhappily,If I could change into my Silkie form, I could really examine it.
But he dared not, could not. At least, he couldn"t do it and simultaneously maintain his safe position.
Silkies had one weakness, if it could be called that. They were vulnerable when they changed from one form to an-other. Considering this, Cemp now conducted his first mental conversation with Joanne. He explained his predica-ment, described what he had learned, and ended, "I think I can stay here all day and see what comes of this, but I should probably have another Silkie stand by for emergencies."
Her anxious reply was, "I"ll have Charley Baxter contact you."
4.
She phoned Baxter and pa.s.sed the conversation on to Cemp in thought form.
Baxter was enormously excited by the information that Cemp had obtained about the alien Silkies. He regarded the gravity field as a new energy application, but he was reluctant to send in another Silkie.
"Let"s face it, Joanne," he said. "Your husband learned something last year which, if other Silkies understood it, might wreck the delicate balance by which we are maintain-ing our present Silkie-human civilization. Nat understands our concern about that. So tell him I"ll send a machine in there to act as a barrier for him while he makes his change-over into Silkie."
It occurred to Cemp that the appearance of new, hitherto unknown Silkies would alter the Silkie-human relationship even more. But he did not permit that thought to go out to Joanne.
Baxter"s conversation concluded with the statement that it would probably take a while before the machine could be got to him. "So tell him to hold on."
After Baxter had hung up, Joanne thought at Cemp, "I should tell you that I am relieved about one thing."
"What"s that?"
"If the Silkie women are all as plain in human form as B-Roth, then I"m not going to worry."
An hour went by. Two ... ten.
In the world outside, the skies would be dark, the sun long gone, the stars signaling in their tiny brilliant fashion.
Charley Baxter"s machine had come and gone, and Cemp, safe in the Silkie form, remained close to the most remark-able energy field that had ever been seen in the solar system. What was astounding was that it showed no diminution of its colossal gravity effect. His hope had been that with hissupersensitiveSilkie perception he would be able to perceive any feeder lines that might be flowing power to it from an outside source. But there was nothing like that; nothing to trace. The power came from the single small group of molecules. It had no other origin.
The minutes and the hours lengthened. The watch became long, and he had time to feel the emotional impact of the problem that now confronted every Silkie on Earth-the need to make a decision about the s.p.a.ce Silkies.
Morning.
Shortly after the sun came up outside, the field manifested an independent quality. It began to move along the corridor, heading deeper into the cave. Cemp floated along after it, letting a portion of its gravitational pull draw him. He was wary but curious, hopeful that now he would find out more.
The cave ended abruptly in a deep sewer, which had the look of long abandonment. The concrete was cracked, and there were innumerable deep fissures in the walls. But to the group of molecules and their field, it seemed to be a familiar area, for they went forward more rapidly. Suddenly, there was water below them. It was not stagnant, but rippled and swirled. A tidal pool, Cemp a.n.a.lyzed.
The water grew deeper, and presently they were in it, traveling at undiminished speed. Ahead, the murky depths grew less murky. They emerged into sunlit waters in a canyon about a hundred feet below the surface of the ocean.
As they broke surface a moment later, the strange energy complex accelerated. Cemp, suspecting that it would now try to get away from him, made a final effort to perceive its characteristics.
But nothing came back to him. No message, no sign of energy flow. For a split second, he did have the impression that the atoms making up the molecule group were some-how ... not right. But when he switched his attention to the band involved, either the molecules became aware of his momentary awareness and closed themselves off or he imagined it.
Even as he made the a.n.a.lysis, his feeling that he was about to be discarded was borne out. The particle"s speed increased rapidly. In seconds, its velocity approached the limits of what he could permit himself to endure inside an atmosphere. The outer chitin of his Silkie body grew hot, then hotter.
Reluctantly, Cemp adjusted his own atomic structure, so that the gravity of the alien field no longer affected him. As he fell away, it continued to pursue a course that took an easterly direction, where the sun was now about an hour above the horizon. Within mere seconds of his separation from it, it left the atmosphere and, traveling at many miles a second, headed seemingly straight for the sun.
Cemp came to the atmosphere"s edge. "Gazing" by means of his Silkie perceptors out upon the vast, dark ocean of s.p.a.ce beyond, he contacted the nearest Telstar unit. To the scientists aboard, he gave a fix on the speeding molecule group. Then he waited hopefully while they tried to put a tracer on it.
But the word finally came, "Sorry, we get no reaction."
Baffled, Cemp let himself be drawn by Earth"s gravity. Then, by a series of controlled adjustments to the magnetic and gravity fields of the planet, he guided himself to the Silkie Authority.
5.
Three hours of talk ...
Cemp, who, as the only Silkie present, occupied a seat near the foot of the long table, found the discussion boring.
It had early seemed to him that he or some other Silkie ought to be sent to the Silkie planetoid to learn the facts, handle the matter in a strictly logical but humanitarian fashion, and report back to the Authority.
If, for some reason, the so-called Silkie nation proved unamenable to reason, then a further discussion would be in order.
As he waited for the three dozen human conferees to reach the same decision, he couldn"t help but notice the order of importance at the table.
The Special People, including Charley Baxter, were at the head of the long table. Next, ranging down on either side, were the ordinary human beings. Then, on one side, himself, and below him, three minor aides and the official secretary of the three-man Silkie Authority.
It was not a new observation for him. He had discussed it with other Silkies, and it had been pointed out to him that here was a reversal of the power role that was new in history. The strongest individuals in the solar system-the Silkies were still relegated to secondary status.
He emerged from his reverie to realize that silence had fallen. Charley Baxter, slim, gray-eyed, intense, was coming around the long table. He stopped across from Cemp.
"Well, Nat," said Baxter, "there"s the picture as we see it." He seemed embarra.s.sed.
Cemp did a lightning mental backtrack on the discussion and realized that they had indeed arrived at the inevitable conclusion. But he noted also that they considered it a weighty decision. It was a lot to ask of any person, that was the att.i.tude. The result could be personal disaster. They wouldn"t be critical if he refused.
"I feel ashamed to ask it," said Baxter, "but this is almost a war situation."
Cemp could see that they were not sure of themselves. There had been no war on Earth for a hundred and fifty years. No one was an expert in it any more.
He climbed to his feet as these awarenesses touched him. Now he looked around at the faces turned to him and said, "Calm yourselves, gentlemen. Naturally I"ll do it."
They all looked relieved. The discussion turned quickly to details-the difficulty of locating a single meteorite in s.p.a.ce, particularly one that had such a long sidereal period.
It was well known that there were about fifteen hundred large meteorites and planetoids and tens of thousands of smaller objects...o...b..ting the sun. All these had orbits or motions that, though subject to the laws of celestial mech-anics, were often very eccentric. A few of them, like comets, periodically came in close to the sun, then shot off into s.p.a.ce again, returning for another hectic go-round fifty to a hundred years later. There were so many of these inter-mediate-sized rocks that they were identified and their courses plotted only for special reasons. There had simply never been any point in tracking them all.
Cemp had matched course with and landed on scores of lone meteorites. His recollections of those experiences were among the bleaker memories of his numerous s.p.a.ce flights-the darkness, the sense of utterly barren rock, the profound lack of sensory stimulation. Oddly, the larger they were, the worse the feeling was.
He had discovered that he could have a kind of intellectual affinity with a rock less than a thousand feet in diameter. This was particularly true when he encountered an in-articulate ma.s.s that had finally been precipitated into a hyperbolic orbit. When he computed that it was thus destined to leave the solar system forever, he would find himself imagining how long it had been in s.p.a.ce, how far it had gone, and how it would now hurtle away from the solar system and spend eons between the stars, and he could not help feeling a sense of loss.
A government representative-a human being named John Mathews-interrupted his thought. "Mr.
Cemp, I"d like to ask you a very personal question."
Cemp looked at him and nodded.
The man went on, "According to reports, several hundred Earth Silkies have already defected to these native Silkies. Evidently, you don"t feel as they do, that the Silkie planetoid is home. Why not?"
Cemp smiled. "Well, first of all," he said, "I would never buy a pig in a poke the way they have done."
He hesitated. Then, in a serious tone, he continued."Entirely apart from my feelings of loyalty to Earth, I do not believe the future of life forms will be helped or advanced by any rigid adherence to the idea that I am a lion, or I am a bear. Intelligent life is, or should be, moving toward a common civilization. Maybe I"m like the farm boy who went to the city-Earth. Now my folks want me to come back to the farm.
They"ll never understand why I can"t, so I don"t even try to explain it to them."
"Maybe," said Mathews, "the planetoid is actually the big city and Earth the farm. What then?"
Cemp smiled politely but merely shook his head.
Mathewspersisted, "One more question. How should Silkies be treated?"
Cemp spread his hands. "I can"t think of a single change that would be of value."
