The Human Edge

  "Do we have record films of the battle?" Joe asked.

  "I'll get them." Maury went off.

  He brought the films. Joe, feeling the weakness of his condition stealing up on him, pushed it aside and set to examining the pictorial record of the battle. Seen in the film viewer, the battle had a remote quality. The alien ship was smaller than Joe had thought, half the size of the Harrier. The two dropped weights had made large holes in its midships. It was not surprising that it had broken apart when rammed.

  One of the halves of the broken ship had gone up and melted in a sudden flare of green light like their weapons beam, as if some internal explosion had taken place. The other half had fallen parallel to the Harrier and almost as slowly—as if the fragment, like the dying Harrier, had had yet some powers of flight—and had been lost to sight at last on the opposite side of this mountain, still falling.

  Four gray bodies had spilled from the alien ship as it broke apart. Three, at least, had fallen some five miles to their deaths. The record camera had followed their dwindling bodies. And Maury was right; these had been changing even as they fell, flattening and spreading out as if in an instinctive effort to slow their fall. But, slowed or not, a five-mile fall even in this lesser-than-Earth gravity was death.

  Joe put the films aside and began to ask Maury questions.

  The Harrier, Maury told him, would never lift again. Half her drive section was melted down to magnesium alloy slag. She lay here with food supplies adequate for the men who were left for four months. Water was no problem as long as everyone existed still within the ship's recycling system. Oxygen was available in the local atmosphere and respirators would extract it. Storage units gave them housekeeping power for ten years. There was no shortage of medical supplies, the tool shop could fashion ordinary implements, and there was a good stock of usual equipment.

  But there was no way of getting off this mountain.

  The others had come into the bubble while Maury had been speaking. They stood now around the bed. With the single exception of Cal, who showed nothing, they all had a new, taut, skinned-down look about their faces, like men who have been recently exhausted or driven beyond their abilities.

  "Look around you," said Jeff Ramsey, taking over from Maury when Maury spoke of the mountain. "Without help we can't leave here."

  "Tell him," said Doug Kellas. Like young Jeff, Doug had not shaved recently. But where Jeff's stubble of beard was blond, Doug's was brown-dark and now marked out the hollows under his youthful cheekbones. The two had been the youngest of the Team.

  "Well, this is a hanging valley," said Jeff. Jeff was the surface man geologist and meteorologist of the Team. "At one time a glacier used to come down this valley we're lying in, and over that edge there. Then the valley subsided, or the mountain rose or the climate changed. All the slopes below that cliff edge—any way down from here—brings you finally to a sheer cliff."

  "How could the land raise that much?" murmured Maury, looking out and down at the green too far below to tell what it represented. Jeff shrugged.

  "This is a bigger world than Earth—even if it's lighter," he said. "Possibly more liable to crustal distortion." He nodded at the peaks above them. "These are young mountains. Their height alone reflects the lesser gravity. That glacier up there couldn't have formed on that steep a slope on Earth."

  "There's the Messenger," said Cal.

  His deeper-toned voice brought them all around. He had been standing behind the rest, looking over their heads. He smiled a little dryly and sadly at the faint unanimous look of hostility on the faces of all but the Survey Leader's. He was unusual in the respect that he was so built as not to need their friendship. But he was a member of the Team as they were and he would have liked to have had that friendship—if it could have been had at any price short of changing his own naturally individualistic character.

  "There's no hope of that," said Doug Kellas. "The Messenger was designed for launching from the ship in space. Even in spite of the lower gravity here, it'd never break loose of the planet."

  The Messenger was an emergency device every ship carried. It was essentially a miniature ship in itself, with drive unit and controls for one shift through no-time and an attached propulsive unit to kick it well clear of any gravitic field that might inhibit the shift into no-time. It could be set with the location of a ship wishing to send a message back to Earth, and with the location of Earth at the moment of arrival—both figured in terms of angle and distance from the theoretical centerpoint of the galaxy, as determined by ship's observations. It would set off, translate itself through no-time in one jump back to a reception area just outside Earth's critical gravitic field, and there be picked up with the message it contained.

  For the Harrier team, this message could tell of the aliens and call for rescue. All that was needed was the precise information concerning the Harrier's location in relation to Galactic Centerpoint and Earth's location.

  * * *

  In the present instance, this was no problem. The ship's computer log developed the known position and movement of Earth with regard to Centerpoint, with every shift and movement of the ship. And the position of the second planet of star K94 was known to the chartmakers of Earth recorded by last observation aboard the Harrier.

  Travel in no-time made no difficulty of distance. In no-time all points coincided, and the ship was theoretically touching them all. Distance was not important, but location was. And a precise location was impossible—the very time taken to calculate it would be enough to render it impossibly inaccurate. What ships travelling by no-time operated on were calculations approximately as correct as possible—and leave a safety factor, read the rulebook.

  Calculate not to the destination, but to a point safely short enough of it, so that the predictable error will not bring the ship out in the center of some solid body. Calculate safely short of the distance remaining . . . and so on by smaller and smaller jumps to a safe conclusion.

  But that was with men aboard. With a mechanical unit like the Messenger, a one-jump risk could be taken.

  The Harrier had the figures to risk it—but a no-time drive could not operate within the critical area of a gravitic field like this planet's. And, as Jeff had said, the propulsive unit of the Messenger was not powerful enough to take off from this mountainside and fight its way to escape from the planet

  "That was one of the first things I figured," said Jeff, now. "We're more than four miles above this world's sea-level, but it isn't enough. There's too much atmosphere still above us."

  "The Messenger's only two and a half feet long put together," said Maury. "It only weighs fifteen pounds earthside. Can't we send it up on a balloon or something? Did you think of that?"

  "Yes," said Jeff. "We can't calculate exactly the time it would take for a balloon to drift to a firing altitude, and we have to know the time to set the destination controls. We can't improvise any sort of a booster propulsion unit for fear of jarring or affecting the destination controls. The Messenger is meant to be handled carefully and used in just the way it's designed to be used, and that's all." He looked around at them. "Remember, the first rule of a Survey Ship is that it never lands anywhere but Earth."

  "Still," said Cal, who had been calmly waiting while they talked this out, "we can make the Messenger work."

  "How?" challenged Doug, turning on him. "Just how?"

  Cal turned and pointed to the wind-piping battlemented peaks of the mountain looming far above.

  "I did some calculating myself," he said. "If we climb up there and send the Messenger off from the top, it'll break free and go."

  * * *

  None of the rest of them said anything for a moment. They had all turned and were looking up the steep slope of the mountain, at the cliffs, the glacier where no glacier should be able to hang, and the peaks.

  "Any of you had any mountain-climbing experience?" asked Joe.

  "There was a rock-climbing club at the Un
iversity I went to," said Cal. "They used to practice on the rock walls of the bluffs on the St. Croix River—that's about sixty miles west of Minneapolis and St. Paul. I went out with them a few times."

  No one else said anything. Now they were looking at Cal.

  "And," said Joe, "as our nearest thing to an expert, you think that"—he nodded to the mountain—"can be climbed carrying the Messenger along?"

  Cal nodded.

  "Yes," he said slowly. "I think it can. I'll carry the Messenger myself. We'll have to make ourselves some equipment in the tool shop, here at the ship. And I'll need help going up the mountain."

  "How many?" said Joe.

  "Three." Cal looked around at them as he called their names. "Maury, Jeff and Doug. All the able-bodied we've got."

  Joe was growing paler with the effort of the conversation.

  "What about John?" he asked looking past Doug at John Martin, Number Nine of the Survey Team. John was a short, rugged man with wiry hair—but right now his face was almost as pale as Joe's, and his warmsuit bulged over the chest.

  "John got slashed up when he tried to pull the alien off you," said Cal calmly. "Just before I shot. He got it clear across the pectoral muscles at the top of his chest. He's no use to me."

  "I'm all right," whispered John. It hurt him even to breathe and he winced in spite of himself at the effort of talking.

  "Not all right to climb a mountain," said Cal. "I'll take Maury, Jeff and Doug."

  "All right. Get at it then." Joe made a little, awkward gesture with his hand, and Maury stooped to help pull the pillows from behind him and help him lie down. "All of you—get on with it."

  "Come with me," said Cal. "I'll show you what we're going to have to build ourselves in the tool shop."

  "I'll be right with you," said Maury. The others went off. Maury stood looking down at Joe. They had been friends and teammates for some years.

  "Shoot," whispered Joe weakly, staring up at him. "Get it off your chest, whatever it is, Maury." The effort of the last few minutes was beginning to tell on Joe. It seemed to him the bed rocked with a seasick motion beneath him, and he longed for sleep.

  "You want Cal to be in charge?" said Maury, staring down at him.

  Joe lifted his head from the pillow. He blinked and made an effort and the bed stopped moving for a moment under him.

  "You don't think Cal should be?" he said.

  Maury simply looked down at him without words. When men work and sometimes die together as happens with tight units like a Survey Team, there is generally a closeness amongst them. This closeness, or the lack of it, is something that is not easily talked about by the men concerned.

  "All right," Joe said. "Here's my reasons for putting him in charge of this. In the first place he's the only one who's done any climbing. Secondly, I think the job is one he deserves." Joe looked squarely back up at the man who was his best friend on the Team. "Maury, you and the rest don't understand Cal. I do. I know that country he was brought up in and I've had access to his personal record. You all blame him for something he can't help."

  "He's never made any attempt to fit in with the Team—"

  "He's not built to fit himself into things. Maury—" Joe struggled up on one elbow. "He's built to make things fit him. Listen, Maury—he's bright enough, isn't he?"

  "I'll give him that," said Maury, grudgingly.

  * * *

  "All right," said Joe. "Now listen. I'm going to violate Department rules and tell you a little bit about what made him what he is. Did you know Cal never saw the inside of a formal school until he was sixteen—and then the school was a university? The uncle and aunt who brought him up in the old voyageur's-trail area of the Minnesota-Canadian border were just brilliant enough and nutty enough to get Cal certified for home education. The result was Cal grew up in the open woods, in a tight little community that was the whole world, as far as he was concerned. And that world was completely indestructible, reasonable and handleable by young Cal Hartlett."

  "But—"

  "Let me talk, Maury. I'm going to this much trouble," said Joe, with effort, "to convince you of something important. Add that background to Cal's natural intellect and you get a very unusual man. Do you happen to be able to guess what Cal's individual sense of security rates out at on the psych profile?"

  "I suppose it's high," said Maury.

  "It isn't simply high—it just isn't," Joe said. "He's off the scale. When he showed up at the University of Minnesota at sixteen and whizzed his way through a special ordering of entrance exams, the psychology department there wanted to put him in a cage with the rest of the experimental animals. He couldn't see it. He refused politely, took his bachelor's degree and went into Survey Studies. And here he is." Joe paused. "That's why he's going to be in charge. These aliens we've bumped into could be the one thing the human race can't match. We've got to get word home. And to get word home, we've got to get someone with the Messenger to the top of that mountain."

  He stopped talking. Maury stood there.

  "You understand me, Maury?" said Joe. "I'm Survey Leader. It's my responsibility. And in my opinion if there's one man who can get the Messenger to the top of the mountain, it's Cal."

  The bed seemed to make a slow half-swing under him suddenly. He lost his balance. He toppled back off the support of his elbow, and the sky overhead beyond the bubble began to rotate slowly around him and things blurred.

  Desperately he fought to hold on to consciousness. He had to convince Maury, he thought. If he could convince Maury, the others would fall in line. He knew what was wrong with them in their feelings toward Cal as a leader. It was the fact that the mountain was unclimbable. Anyone could see it was unclimbable. But Cal was going to climb it anyway, they all knew that, and in climbing it he would probably require the lives of the men who went with him.

  They would not have minded that if he had been one of them. But he had always stood apart, and it was a cold way to give your life—for a man whom you had never understood, or been able to get close to.

  "Maury," he choked. "Try to see it from Cal's—try to see it from his—"

  The sky spun into a blur. The world blurred and tilted.

  "Orders," Joe croaked at Maury. "Cal—command—"

  "Yes," said Maury, pressing him back down on the bed as he tried blindly to sit up again. "All right. All right, Joe. Lie still. He'll have the command. He'll be in charge and we'll all follow him. I promise . . ."

  IV

  During the next two days, the Survey Leader was only intermittently conscious. His fever ran to dangerous levels, and several times he trembled and jerked as if on the verge of going into convulsions. John Martin also, although he was conscious and able to move around and even do simple tasks, was pale, high-fevered and occasionally thick-tongued for no apparent reason. It seemed possible there was an infective agent in the claw and teeth wounds made by the alien, with which the ship's medicines were having trouble coping.

  With the morning of the third day when the climbers were about to set out both men showed improvement.

  The Survey Leader came suddenly back to clearheadedness as Cal and the three others were standing, all equipped in the bubble, ready to leave. They had been discussing last-minute warnings and advices with a pale but alert John Martin when Joe's voice entered the conversation.

  "What?" it said. "Who's alive? What was that?"

  They turned and saw him propped up on one elbow on his makeshift bed. They had left him on it since the sleeping quarters section of the ship had been completely destroyed, and the sections left unharmed were too full of equipment to make practical places for the care of a wounded man. Now they saw his eyes taking in their respirator masks, packs, hammers, the homemade pitons and hammers, and other equipment including rope, slung about them.

  "What did one of you say?" Joe demanded again. "What was it?"

  "Nothing, Joe," said John Martin, coming toward him. "Lie down."

  Joe waved him away, fro
wning. "Something about one being still alive. One what?"

  Cal looked down at him. Joe's face had grown lean and fallen in even in these few days but the eyes in the face were sensible.

  "He should know," Cal said. His calm, hard, oddly carrying baritone quieted them all. "He's still Survey Leader." He looked around at the rest but no one challenged his decision. He turned and went into the corridor of the ship, down to the main control room, took several photo prints from a drawer and brought them back. When he got back out, he found Joe now propped up on pillows but waiting.

  "Here," said Cal, handing Joe the photos. "We sent survey rockets with cameras over the ridge up there for a look at the other side of the mountain. That top picture shows you what they saw."

  Joe looked down at the top picture that showed a stony mountainside steeper than the one the Harrier lay on. On this rocky slope was what looked like the jagged, broken-off end of a blackened oil drum—with something white spilled out on the rock by the open end of the drum.

  "That's what's left of the alien ship," said Cal. "Look at the closeup on the next picture."

  * * *

  Joe discarded the top photo and looked at the one beneath. Enlarged in the second picture he saw that the white something was the body of an alien, lying sprawled out and stiff.

  "He's dead, all right," said Cal. "He's been dead a day or two anyway. But take a good look at the whole scene and tell me how it strikes you."

  Joe stared at the photo with concentration. For a long moment he said nothing. Then he shook his head, slowly.

  "Something's phony," he said at last, huskily.

  "I think so too," said Cal. He sat down on the makeshift bed beside Joe and his weight tilted the wounded man a little toward him. He pointed to the dead alien. "Look at him. He's got nothing in the way of a piece of equipment he was trying to put outside the ship before he died. And that mountainside's as bare as ours. There was no place for him to go outside the ship that made any sense as a destination if he was that close to dying. And if you're dying on a strange world, do you crawl out of the one familiar place that's there with you?"
