Humans could hear frequencies up to 20,000 a second. That was where some races started to hear. Under hypnosis, men could be conditioned to laugh uproariously when they were being tortured, and shriek with pain when tickled. Stimulation that meant pain to one life form, could mean nothing at all to another.

Mentally, Grosvenor let the tensions seep out of him. There was nothing for him to do but to relax and wait. He waited.

It occurred to him presently that there might be a connection between his own thoughts and the sensations he received. That picture of the inside of the building--what had he thought just before it came? Princ.i.p.ally, he recalled, he had visualized the structure of the eye. The connection was so obvious that his mind trembled with excitement. There was another thing, also. Until now, he had concentrated on the notion of seeing and feeling with the nervous system of the individual. Still the realization of his hopes depended on his establishing contact with, and control of, the group of minds that had attacked the ship.

He saw his problem, suddenly, as one that would require control of his own brain. Certain areas would have to be virtually blacked out, kept at minimum performance levels. Others must be made extremely sensitive, so that all incoming sensations found it easier to seek expression through them. As a highly trained auto-hypnotic subject, he could accomplish both objectives by suggestion. Vision came first, of course. Then muscular control of the individual, through whom the group was working against him.

Flashes of colored light interrupted his concentration. Grosvenor regarded them as evidence of the effectiveness of his suggestions. He knew that he was on the right track when his vision cleared suddenly, and stayed clear. The scene was the same. His control still sat on one of the roosts inside one of the tall buildings. Hoping fervently that the vision was not going to fade, Grosvenor began to concentrate on moving the Riim's muscles. The trouble was that the ultimate explanation of why a movement could occur at all was obscure. His visualization had to be on a level that was already gross. Nothing happened. Shocked but determined, Grosvenor tried symbol hypnosis, using a single cue word to cover the entire complex process.

Slowly, one of the attenuated arms came up. Another cue, and his control stood up cautiously. Then he made it turn its head. The act of looking reminded the bird-being that that drawer and that cabinet and that closet were "mine". The memory barely touched the conscious level. The creature knew its own possessions and accepted the fact without concern.

Grosvenor had a hard time fighting down his excitement. With tense patience, he had the bird-being get up from a sitting position, raise its arms, lower them, and walk back and forth along the roost. Finally, he made it sit down again. He must have been keyed up, his brain responsive to the slightest suggestion. Because he had barely started to concentrate again when his whole being was flooded by a message that seemed to affect every level of his thought and feeling. More or less automatically, Grosvenor translated the anguished thoughts into familiar verbalisms.

"... The cells are calling, calling. The cells are afraid. Oh, the cells know pain! There is darkness in the Riim world. Withdraw from the being--far from Riim ... Shadows, darkness, turmoil ... The Cells must reject him ... but they cannot. They were right to try to destroy the being who came out of the great dark. The night deepens. All cells withdraw ... but they cannot ..."

Grosvenor thought exultantly: "I've got them!" After a minute of tremendous excitement, he grew sober. His problem was greater than theirs. If he broke his connection with them, they would be free. By avoiding him thereafter, they could go on to achieve the purpose of their disruptive attack ... destruction of the s.p.a.ce Beagle. He would still have the problem of overcoming Morton and the others. He had no alternative but to go on with his plan.

He concentrated first on what seemed the most logical intermediate stage:--the transfer of control to another alien. The choice, in the case of these beings, was obvious.

"I am loved!" he told himself, deliberately producing the sensation which had confused him earlier. "I am loved by my parent body, from which I am growing to wholeness. I share my parent's thoughts, but already I see with my own eyes, and know that I am one of the group ..."

The transition came suddenly, as Grosvenor had expected it might. He moved the smaller, duplicate fingers. He arched the fragile shoulders. Then he oriented himself again to the parent Riim. The experiment was so completely satisfactory that he felt ready for the bigger jump that would take him into a.s.sociation with the nervous system of a more distant alien. That, also, proved to be a matter of stimulating the proper brain centers. Grosvenor came to awareness standing in a wilderness of brush and hill. Directly in front of him was a narrow stream, and beyond it, an orange sun rode low in a dark purple sky that was spotted with fleecy clouds. Grosvenor made his new control turn completely around. He saw that a small roost building, the only habitation in sight, nestled among the trees farther along the stream. He walked toward the building and looked inside. In the dim interior, he made out several roosts, one with two birds sitting on it, both with eyes closed. It was quite possible, he decided, that they were partic.i.p.ating in the group a.s.sault on the s.p.a.ce Beagle.

From there, by a variation of the stimulus, he transferred his control to an individual on a part of the planet where it was night. The transition this time was even faster. He was in a lightless city, with ghostly buildings and catwalks. Swiftly, Grosvenor moved on to a.s.sociation with other nervous systems. He had no clear idea why the "rapport" was established with one Riim, and not with another who fitted the same general requirement. It could be that the stimulations affected some individuals slightly faster than it affected others. It was even possible that these were descendants or body-relatives of his original parent-control. When he had been a.s.sociated with more than two dozen Riim all over the planet, it seemed to Grosvenor that he had a good, over-all impression.

It was a world of brick and stone and wood, and of a neurological community relationship that would probably never be surpa.s.sed. A race had by-pa.s.sed the entire machine-age of man, with its penetration of the secrets of matter' and energy. Now, he felt, he could safely take the next-to-the-last step of his counter-attack. He concentrated on a pattern which would characterize one of the beings who had projected an image to the s.p.a.ce Beagle. (He had, then, a sense of a small but noticeable lapse of time.) Then he was looking forth from one of the images, seeing the ship through an image.

His first concern was with how the battle was progressing, but he had to restrain his will to know because to come aboard was only part of his necessary pre-conditioning. He wanted to affect a group of perhaps millions of individuals, and had to affect them so powerfully that they would have to withdraw from the s.p.a.ce Beagle, and have no recourse but to stay away from it.

He had proved that he could receive their thoughts, and that they could receive his. His a.s.sociation with one nervous system after another would not have been possible unless that was so. Now he was ready. He thought into the darkness: "You live in a Universe; and within you, you form pictures of the Universe as it seems to you. Of that Universe you know nothing and can know nothing except for the pictures, but the pictures within you of the Universe are not the Universe ..."

How could you influence another's mind?--By changing his a.s.sumptions. How could you alter another's actions?--By changing his basic beliefs, his emotional certainties.

Carefully, Grosvenor went on: "And the pictures within you do not show all about the Universe, for there are many things which you cannot know directly, not having senses to know. Within the Universe there is an order, and if the order of the pictures within you is not as the order of the Universe, then you are deceived ..."

In the history of life, few thinking beings had ever done anything illogical--within their frame of reference. If the frame was falsely based, if the a.s.sumptions were untrue to reality, then the individual's automatic logic could lead him to disastrous conclusions.

The a.s.sumptions had to be changed. Grosvenor changed them, deliberately, coolly, honestly. His own basic hypothesis behind what he was doing was that the Riim had no defense. These were the first new ideas they had had in countless generations and he did not doubt that the impact would be colossal. This was a fellah civilization, rooted in certainties that had never before been challenged. There was ample historical evidence that a tiny intruder could influence decisively the future of entire fellahin races.

Huge old India had crumbled before a few thousand Englishmen. Similarly, all the fellah peoples of ancient Earth were taken over with ease, and did not revive till the core of their inflexible att.i.tudes was forever shattered by the dawning realization that there was more to life than they had been taught under their rigid systems. The Riim were peculiarly vulnerable. Their method of communication, unique and wonderful though it was, made it possible to influence them all in a single intensive operation. Over and over, Grosvenor repeated his message, adding, each time, one instruction that had to do with the ship. The instruction was: "Change the pattern you are using against those on the ship, and then withdraw it. Change the pattern, so that they can relax, and sleep ... then withdraw it ... do not attack again ..."

He had only a vague notion as to how long he actually poured his commands into that tremendous neural circuit. He guessed about two hours. Whatever the time involved, it ended as the relay switch on the encephalo-adjuster automatically broke the connection between himself and the image in the wall of his department. Abruptly, he was aware of the familiar surroundings of his own department. He glanced at where the image had been and tensed as he saw that it was still there, but shook his head slightly. He could hardly expect a definite reaction this soon. The Riim, also, were recovering from a connection that had just been broken.

As Grosvenor watched, the pattern of light from the image changed subtly. Grosvenor's head drooped sleepily. He sat up jerkily, remembering. The instructions he had given--to relax and sleep--this was the result. All over the ship, men would be sleeping as the new hypnotic pattern extended its inhibitory paralysis over the hemispheres of the brain.

About three minutes went by. Suddenly, the double image of the Riim vanished from the glistening wall in front of him. A moment later, Grosvenor was out in the corridor. As he raced along, he saw that unconscious men lay everywhere but that the walls were bright and clear. Not once on his journey to the control room did he see an image.

Inside the control room, he stepped gingerly over the sleeping form of Captain Leeth, who lay on the floor near the control panel. With a sigh of relief, Grosvenor threw the switch that energized the outer screen of the ship.

Seconds later, Elliott Grosvenor was in the control chair, altering the course of the s.p.a.ce Beagle.

THE EXPENDABLES.

1.

ONE HUNDRED and nine years after leaving Earth, the s.p.a.ceship, Hope of Man, went into orbit around Alta III.

The following "morning" Captain Browne informed the shipload of fourth and fifth generation colonists that a manned lifeboat would be dropped to the planet's surface.

"Every member of the crew must consider himself expendable," he said earnestly. "This is the day that our great grandparents, our forefathers, who boldly set out for the new s.p.a.ce frontier so long ago, looked forward to with unfaltering courage. We must not fail them."

He concluded his announcement over the intercom system of the big ship by saying that the names of the crew members of the lifeboat would be given out within the hour. "And I know that every real man aboard will want to see his name there."

John Lesbee, the fifth of his line aboard, had a sinking sensation as he heard those words--and he was not mistaken.

Even as he tried to decide if he should give the signal for a desperate act of rebellion, Captain Browne made the expected announcement.

The commander said, "And I know you will all join him in his moment of pride and courage when I tell you that John Lesbee will lead the crew that carries the hopes of man in this remote area of s.p.a.ce. And now the others--"

He thereupon named seven of the nine persons with whom Lesbee had been conspiring to seize control of the ship.

Since the lifeboat would only hold eight persons, Lesbee recognized that Browne was dispatching as many of his enemies as he could. He listened with a developing dismay, as the commander ordered all persons on the ship to come to the recreation room. "Here I request that the crew of the lifeboat join me and the other officers on stage. Their instructions are to surrender themselves to any craft which seeks to intercept them. They will be equipped with instruments whereby we here can watch, and determine the stage of scientific attainments of the dominant race on the planet below."

Lesbee hurried to his room on the technicians' deck, hoping that perhaps Tellier or Cantlin would seek him out there. He felt himself in need of a council of war, however brief. He waited five minutes, but not one member of his conspiratorial group showed.

Nonetheless, he had time to grow calm. Peculiarly, it was the smell of the ship that soothed him most. From the earliest days of his life, the odor of energy and the scent of metal under stress had been perpetual companions. At the moment, with the ship in orbit, there was a letting up of stress. The smell was of old energies rather than new. But the effect was similar.

He sat in the chair he used for reading, eyes closed, breathing in that complex of odors, product of so many t.i.tanic energies. Sitting there, he felt the fear leave his mind and body. He grew brave again, and strong.

Lesbee recognized soberly that his plan to seize power had involved risks. Worse, no one would question Browne's choice of him, as the leader of the mission. "I am," thought Lesbee, "probably the most highly trained technician ever to be on this ship." Browne Three had taken him when he was ten, and started him on the long grind of learning that led him, one after the other, to master the mechanical skills of all the various technical departments. And Browne Four had continued his training.

He was taught how to repair relay systems. He gradually came to understand the purposes of countless a.n.a.logs. The time came when he could visualize the entire automation. Long ago, the colossal cobweb of electronic instruments within the walls had become almost an extension of his nervous system.

During those years of work and study, each daily apprenticeship ch.o.r.e left his slim body exhausted. After he came off duty, he sought a brief relaxation and usually retired to an early rest.

He never did find the time to learn the intricate theory that underlay the ship's many operations.

His father, while he was alive, had made numerous attempts to pa.s.s his knowledge on to his son. But it was hard to teach complexities to a tired and sleepy boy. Lesbee even felt slightly relieved when his parent died. It took the pressure off him. Since then, however, he had come to realize that the Browne family, by forcing a lesser skill on the descendant of the original commander of the ship, had won their greatest victory.

As he headed finally for the recreation room, Lesbee found himself wondering: Had the Brownes trained him with the intention of preparing him for such a mission as this?

His eyes widened. If that was true, then his own conspiracy was merely an excuse. The decision to kill him might actually have been made more than a decade ago, and light years away ...

As the lifeboat fell toward Alta III, Lesbee and Tellier sat in the twin control chairs and watched on the forward screen the vast, misty atmosphere of the planet.

Tellier was thin and intellectual, a descendant of the physicist Dr Tellier who had made many speed experiments in the early days of the voyage. It had never been understood why s.p.a.ceships could not attain even a good fraction of the speed of light, let alone velocities greater than light. When the scientist met his untimely death, there was no one with the training to carry on a testing program.

It was vaguely believed by the trained personnel who succeeded Tellier that the ship had run into one of the paradoxes implicit in the Lorenz-Fitzgerald Contraction theory.

Whatever the explanation, it was never solved.

Watching Tellier, Lesbee wondered if his companion and best friend felt as empty inside as he did. Incredibly, this was the first time he--or anyone--had been outside the big ship. "We're actually heading down," he thought, "to one of those great ma.s.ses of land and water, a planet."

As he watched, fascinated, the ma.s.sive ball grew visibly bigger.

They came in at a slant, a long, swift, angling approach, ready to jet away if any of the natural radiation belts proved too much for their defense systems. But as each stage of radiation registered in turn, the dials showed that the lifeboat machinery made the proper responses automatically.

The silence was shattered suddenly by an alarm bell.

Simultaneously, one of the screens focused on a point of rapidly moving light far below. The light darted toward them.

A missile!

Lesbee caught his breath.

But the shining projectile veered off, turned completely around, took up position several miles away, and began to fall with them.

His first thought was: "They'll never let us land," and he experienced an intense disappointment.

Another signal brrred from the control board.

"They're probing us," said Tellier, tensely.

An instant after the words were uttered, the lifeboat seemed to shudder and to stiffen under them. It was the unmistakable feel of a tractor beam. Its field clutched the lifeboat, drew it, held it."

The science of the Alta III inhabitants was already proving itself formidable.

Underneath him the lifeboat continued its movement.

The entire crew gathered around and watched as the point of brightness resolved into an object, which rapidly grew larger. It loomed up close, bigger than they.

There was a metallic b.u.mp. The lifeboat shuddered from stem to stern.

Even before the vibrations ceased Tellier said, "Notice they put our airlock against theirs."

Behind Lesbee, his companions began that peculiar joking of the threatened. It was a coa.r.s.e comedy, but it had enough actual humor suddenly to break through his fear. Involuntarily he found himself laughing.

Then, momentarily free of anxiety, aware that Browne was watching and that there was no escape, he said, "Open the airlock! Let the aliens capture us as ordered."

2.

A few minutes after the outer airlock was opened, the airlock of the alien ship folded back also. Rubberized devices rolled out and contacted the Earth lifeboat, sealing off both entrances from the vacuum of s.p.a.ce.

Air hissed into the interlocking pa.s.sageway between the two craft. In the alien craft's lock, an inner door opened.

Again Lesbee held his breath.

There was a movement in the pa.s.sageway. A creature ambled into view. The being came forward with complete a.s.surance, and pounded with something he held at the end of one of his four leathery arms on the hull.

The creature had four legs and four arms, and a long thin body held straight up. It had almost no neck, yet the many skin folds between the head and the body indicated great flexibility was possible.

Even as Lesbee noted the details of its appearance, the being turned his head slightly, and its two large expressionless eyes gazed straight at the hidden wall receptor that was photographing the scene, and therefore straight into Lesbee's eyes.

Lesbee blinked at the creature, then tore his gaze away, swallowed hard, and nodded at Tellier. "Open up!" he commanded.

The moment the inner door of the Earth lifeboat opened, six more of the four-legged beings appeared one after another in the pa.s.sageway, and walked forward in the same confident way as had the first.

All seven creatures entered the open door of the lifeboat.

As they entered, their thoughts came instantly into Lesbee's mind ...

As Dzing and his boarding party trotted from the small Karn ship through the connecting airlock, his chief officer thought a message to him.

"Air pressure and oxygen content are within a tiny percentage of what exists at ground level on Karn. They can certainly live on our planet."

Dzing moved forward into the Earth ship, and realized that he was in the craft's control chamber. There, for the first time, he saw the men. He and his crew ceased their forward motion; and the two groups of beings--the humans and the Karn--gazed at each other.

The appearance of the two-legged beings did not surprise Dzing. Pulse viewers had, earlier, penetrated the metal walls of the lifeboat and had accurately photographed the shape and dimension of those aboard.

His first instruction to his crew was designed to test if the strangers were, in fact, surrendering. He commanded: "Convey to the prisoners that we require them as a precaution to remove their clothing."

... Until that direction was given, Lesbee was still uncertain as to whether or not these beings could receive human thoughts as he was receiving theirs. From the first moment, the aliens had conducted their mental conversations as if they were unaware of the thoughts of the human beings. Now he watched the Karn come forward. One tugged suggestively at his clothing. And there was no doubt.

The mental telepathy was a one-way flow only--from the Karn to the humans.

He was already savoring the implications of that as he hastily undressed ... It was absolutely vital that Browne do not find it out.

Lesbee removed all his clothes; then, before laying them down, took out his notebook and pen. Standing there naked he wrote hurriedly: "Don't let on that we can read the minds of these beings."

He handed the notebook around, and he felt a lot better as each of the men read it, and nodded at him silently.

Dzing communicated telepathically with someone on the ground. "These strangers," he reported, "clearly acted under command to surrender. The problem is, how can we now let them overcome us without arousing their suspicion that this is what we want them to do?"

Lesbee did not receive the answer directly. But he picked it up from Dzing's mind: "Start tearing the lifeboat apart. See if that brings a reaction."

The members of the Karn boarding party went to work at once. Off came the control panels; floor plates were melted and ripped up. Soon instruments, wiring, controls were exposed for examination. Most interesting of all to the aliens were the numerous computers and their accessories.
