Arena

by Fredric Brown

  There had to be some way of getting through the barrier, or of killing through the barrier.

  Mentally? He hoped that wasn't all, for the Roller obviously had stronger telepathic powers than the undeveloped ones of the human race. Or did it?

  He had been able to drive the thoughts of the Roller out of his own mind; could it drive out his? If its ability to project were stronger, might not its receptivity mechanism be more vulnerable?

  He stared at it and endeavoured to concentrate and focus all his thought upon it.

  'Die,' he thought. 'You are going to die. You are dying. You are — '

  He tried variations on it, and mental pictures. Sweat stood out on his forehead and he found himself trembling with the intensity of the effort. But the Roller went ahead with its investigation of the bush, as utterly unaffected as though Carson had been reciting the multiplication table.

  So that was no good.

  He felt dizzy from the heat and his strenuous effort at concentration. He sat down on the blue sand and gave his full attention to studying the Roller. By study, perhaps, he could judge its strength and detect its weaknesses, learn things that would be valuable to know when and if they should come to grips.

  It was breaking off twigs. Carson watched carefully, trying to judge just how hard it worked to do that. Later, he thought, he could find a similar bush on his own side, break off twigs of equal thickness himself, and gain a comparison of physical strength between his own arms and hands and those tentacles.

  The twigs broke off hard; the Roller was having to struggle with each one. Each tentacle, he saw, bifurcated at the tip into two fingers, each tipped by a nail or claw. The claws didn't seem to be particularly long or dangerous, or no more so than his own fingernails, if they were left to grow a bit.

  No, on the whole, it didn't look too hard to handle physically. Unless, of course, that bush was made of pretty tough stuff. Carson looked round; within reach was another bush of identically the same type.

  He snapped off a twig. It was brittle, easy to break. Of course, the Roller might have been faking deliberately but he didn't think so. On the other hand, where was it vulnerable? How would he go about killing it if he got the chance? He went back to studying it. The outer hide looked pretty tough; he'd need a sharp weapon of some sort. He picked up the piece of rock again. It was about twelve inches long, narrow, and fairly sharp on one end. If it chipped like flint, he could make a serviceable knife out of it.

  The Roller was continuing its investigations of the bushes. It rolled again, to the nearest one of another type. A little blue lizard, many-legged like the one Carson had seen on his side of the barrier, darted out from under the bush.

  A tentacle of the Roller lashed out and caught it, picked it up. Another tentacle whipped over and began to pull legs off the lizard, as coldly as it had pulled twigs off the bush. The creature struggled frantically and emitted a shrill squealing that was the first sound Carson had heard here, other than the sound of his own voice.

  Carson made himself continue to watch; anything he could learn about his opponent might prove valuable, even knowledge of its unnecessary cruelty — particularly, he thought with sudden emotion, knowledge of its unnecessary cruelty. It would make it a pleasure to kill the thing, if and when the chance came.

  With half its legs gone, the lizard stopped squealing and lay limp in the Roller's grasp.

  It didn't continue with the rest of the legs. Contemptuously it tossed the dead lizard away from it, in Carson's direction. The lizard arced through the air between them and landed at his feet.

  It had come through the barrier! The barrier wasn't there any more! Carson was on his feet in a flash, the knife gripped tightly in his hand, leaping forward. He'd settle this thing here and now! With the barrier gone — but it wasn't gone. He found that out the hard way, running head on into it and nearly knocking himself silly. He bounced back and fell.

  As he sat up, shaking his head to clear it, he saw something coming through the air towards him, and threw himself flat again on the sand, to one side. He got his body out of the way, but there was a sudden sharp pain in the calf of his left leg.

  He rolled backwards, ignoring the pain, and scrambled to his feet. It was a rock, he saw now, that had struck him. And the Roller was picking up another, swinging it back gripped between two tentacles, ready to throw again.

  It sailed through the air towards him, but he was able to step out of its way. The Roller, apparently, could throw straight, but neither hard nor far. The first rock had struck him only because he had been sitting down and had not seen it coming until it was almost upon him.

  Even as he stepped aside from that weak second throw Carson drew back his right arm and let fly with the rock that was still in his hand. If missiles, he thought with elation, can cross the barrier, then two can play at the game of throwing them.

  He couldn't miss a three-foot sphere at only four-yard range, and he didn't miss. The rock whizzed straight, and with a speed several times that of the missiles the Roller had thrown. It hit dead centre, but hit flat instead of point first. But it hit with a resounding thump, and obviously hurt. The Roller had been reaching for another rock, but changed its mind and got out of there instead. By the time Carson could pick up and throw another rock, the Roller was forty yards back from the barrier and going strong.

  His second throw missed by feet, and his third throw was short. The Roller was out of range of any missile heavy enough to be damaging.

  Carson grinned. That round had been his.

  He stopped grinning as he bent over to examine the calf of his leg. A jagged edge of the stone had made a cut several inches long. It was bleeding pretty freely, but he didn't think it had gone deep enough to hit an artery. If it stopped bleeding of its own accord, well and good. If not, he was in for trouble.

  Finding out one thing, though, took precedence over that cut: the nature of the barrier.

  He went forward to it again, this time groping with his hands before him. Holding one hand against it, he tossed a handful of sand at it with the other hand. The sand went right through; his hand didn't.

  Organic matter versus inorganic? No, because the dead lizard had gone through it, and a lizard, alive or dead, was certainly organic. Plant life? He broke off a twig and poked it at the barrier. The twig went through, with no resistance, but when his fingers gripping the twig came to the barrier, they were stopped.

  He couldn't get through it, nor could the Roller. But rocks and sand and a dead lizard.... How about a live lizard?

  He went hunting under bushes until he found one, and caught it. He tossed it against the barrier and it bounced back and scurried away across the blue sand.

  That gave him the answer, so far as he could determine it now. The screen was a barrier to living things. Dead or inorganic matter could cross it.

  With that off his mind, Carson looked at his injured leg again. The bleeding was lessening, which meant he wouldn't need to worry about making a tourniquet. But he should find some water, if any was available, to clean the wound.

  Water — the thought of it made him realize that he was getting awfully thirsty. He'd have to find water, in case this contest turned out to be a protracted one.

  Limping slightly now, he started off to make a circuit of his half of the arena. Guiding himself with one hand along the barrier, he walked to his right until he came to the curving sidewall. It was visible, a dull blue-grey at close range, and the surface of it felt just like the central barrier.

  He experimented by tossing a handful of sand at it, and the sand reached the wall and disappeared as it went through. The hemispherical shell was a force-field, too, but an opaque one, instead of transparent like the barrier.

  He followed it round until he came back to the barrier, and walked back along the barrier to the point from which he'd started.

  No sign of water.

  Worried now, he started a series of zigzags back and forth between the barrier and the wall, cov
ering the intervening space thoroughly.

  No water. Blue sand, blue bushes, and intolerable heat. Nothing else.

  It must be his imagination, he told himself that he was suffering that much from thirst. How long had he been there? Of course, no time at all, according to his own space-time frame. The Entity had told him time stood still out there, while he was here. But his body processes went on here, just the same. According to his body's reckoning, how long had he been here? Three or four hours, perhaps. Certainly not long enough to be suffering from thirst.

  Yet he was suffering from it; his throat was dry and parched. Probably the intense heat was the cause. It was hot, a hundred and thirty Fahrenheit, at a guess. A dry, still heat without the slightest movement of air.

  He was limping rather badly and utterly fagged when he finished the futile exploration of his domain.

  He stared across at the motionless Roller and hoped it was as miserable as he was. The Entity had said the conditions here were equally unfamiliar and uncomfortable for both of them. Maybe the Roller came from a planet where two-hundred-degree heat was the norm; maybe it was freezing while he was roasting. Maybe the air was as much too thick for it as it was too thin for him. For the exertion of his explorations had left him panting. The atmosphere here, he realized, was not much thicker than on Mars.

  No water. That meant a deadline, for him at any rate. Unless he could find a way to cross that barrier or to kill his enemy from this side of it, thirst would kill him eventually.

  It gave him a feeling of desperate urgency, but he made himself sit down a moment to rest, to think.

  What was there to do? Nothing, and yet so many things. The several varieties of bushes, for example; they didn't look promising, but he'd have to examine them for possibilities. And his leg — he'd have to do something about that, even without water to clean it; gather ammunition in the form of rocks; find a rock that would make a good knife.

  His leg hurt rather badly now, and he decided that came first. One type of bush had leaves — or things rather similar to leaves. He pulled off a handful of them and decided, after examination, to take a chance on them. He used them to clean off the sand and dirt and caked blood, then made a pad of fresh leaves and tied it over the wound with tendrils from the same bush.

  The tendrils proved unexpectedly tough and strong.

  They were slender and pliable, yet he couldn't break them at all, and had to saw them off the bush with the sharp edge of blue flint. Some of the thicker ones were over a foot long, and he filed away in his memory, for future reference, the fact that a bunch of the thick ones, tied together, would make a pretty serviceable rope. Maybe he'd be able to think of a use for rope.

  Next, he made himself a knife. The blue flint did chip. From a foot-long splinter of it, he fashioned himself a crude but lethal weapon. And of tendrils from the bush, he made himself a rope-belt through which he could thrust the flint knife, to keep it with him all the time and yet have his hands free.

  He went back to studying the bushes. There were three other types. One was leafless, dry, brittle, rather like a dried tumbleweed. Another was of soft, crumbly wood, almost like punk. It looked and felt as though it would make excellent tinder for a fire. The third type was the most nearly wood-like. It had fragile leaves that wilted at the touch, but the stalks, although short, were straight and strong.

  It was horribly, unbearably hot.

  He limped up to the barrier, felt to make sure that it was still there. It was. He stood watching the Roller for a while; it was keeping a safe distance from the barrier, out of effective stone-throwing range. It was moving around back there, doing something. He couldn't tell what it was doing.

  Once it stopped moving, came a little closer, and seemed to concentrate its attention on him. Again Carson had to fight off a wave of nausea. He threw a stone at it; the Roller retreated and went back to whatever it had been doing before.

  At least he could make it keep its distance. And, he thought bitterly, a lot of good that did him. Just the same, he spent the next hour or two gathering stones of suitable size for throwing, and making several piles of them near his side of the barrier.

  His throat burned now. It was difficult for him to think about anything except water. But he had to think about other things: about getting through that barrier, under or over it, getting at that red sphere and killing it before this place of heat and thirst killed him.

  The barrier went to the wall upon either side, but how high, and how far under the sand?

  For a moment, Carson's mind was too fuzzy to think out how he could find out either of those things. Idly, sitting there in the hot sand — and he didn't remember sitting down — he watched a blue lizard crawl from the shelter of one bush to the shelter of another.

  From under the second bush, it looked out at him.

  Carson grinned at it, recalling the old story of the desert-colonists on Mars, taken from an older story of Earth — 'Pretty soon you get so lonesome you find yourself talking to the lizards, and then not so long after that you find the lizards talking back to you....'

  He should have been concentrating, of course, on how to kill the Roller, but instead he grinned at the lizard and said, 'Hello, there.'

  The lizard took a few steps towards him. 'Hello,' it said.

  Carson was stunned for a moment, and then he put back his head and roared with laughter. It didn't hurt his throat to do so, either; he hadn't been that thirsty.

  Why not? Why should the Entity who thought up this nightmare of a place not have a sense of humour, along with the other powers he had? Talking lizards, equipped to talk back in my own language, if I talk to them — it's a nice touch.

  He grinned at the lizard and said, 'Come on over.' But the lizard turned and ran away, scurrying from bush to bush until it was out of sight.

  He had to get past the barrier. He couldn't get through it, or over it, but was he certain he couldn't get under it? And come to think of it, didn't one sometimes find water by digging?

  Painfully now, Carson limped up to the barrier and started digging, scooping up sand a double handful at a time. It was slow work because the sand ran in at the edges and the deeper he got the bigger in diameter the hole had to be. How many hours it took him, he didn't know, but he hit bedrock four feet down: dry bedrock with no sign of water.

  The force-field of the barrier went down clear to the bedrock.

  He crawled out of the hole and lay there panting, then raised his head to look across and see what the Roller was doing.

  It was making something out of wood from the bushes, tied together with tendrils, a queerly shaped framework about four feet high and roughly square. To see it better, Carson climbed on to the mound of sand he had excavated and stood there staring.

  There were two long levers sticking out of the back of it, one with a cup-shaped affair on the end. Seemed to be some sort of a catapult, Carson thought.

  Sure enough, the Roller was lifting a sizable rock into the cup-shape. One of his tentacles moved the other lever up and down for a while, and then he turned the machine slightly, aiming it, and the lever with the stone flew up and forward.

  The stone curved several yards over Carson's head, so far away that he didn't have to duck, but he judged the distance it had travelled, and whistled softly. He couldn't throw a rock that weight more than half that distance. And even retreating to the rear of his domain wouldn't put him out of range of that machine if the Roller pushed it forward to the barrier.

  Another rock whizzed over, not quite so far away this time.

  Moving from side to side along the barrier, so the catapult couldn't bracket him, he hurled a dozen rocks at it. But that wasn't going to be any good, he saw. They had to be light rocks, or he couldn't throw them that far. If they hit the framework, they bounced off harmlessly. The Roller had no difficulty, at that distance, in moving aside from those that came near it.

  Besides, his arm was tiring badly. He ached all over.

  He stum
bled to the rear of the arena. Even that wasn't any good; the rocks reached back there, too, only there were longer intervals between them, as though it took longer to wind up the mechanism, whatever it was, of the catapult.

  Wearily he dragged himself back to the barrier again. Several times he fell and could barely rise to his feet to go on. He was, he knew, near the limit of his endurance. Yet he didn't dare stop moving now, until and unless he could put that catapult out of action. If he fell asleep, he'd never wake up.

  One of the stones from it gave him the glimmer of an idea. It hit one of the piles of stones he'd gathered near the barrier to use as ammunition and struck sparks.

  Sparks! Fire! Primitive man had made fire by striking sparks, and with some of those dry crumbly bushes as tinder...

  A bush of that type grew near him. He uprooted it, took it over to the pile of stones, then patiently hit one stone against another until a spark touched the punk-like wood of the bush. It went up in flames so fast that it singed his eyebrows and was burned to an ash within seconds.

  But he had the idea now, and within minutes had a little fire going in the lee of the mound of sand he'd made. The tinder bushes started it, and other bushes which burned more slowly kept it a steady flame.

  The tough tendrils didn't burn readily; that made the fire-bombs easy to rig and throw; a bundle of faggots tied about a small stone to give it weight and a loop of the tendril to swing it by.

  He made half a dozen of them before he lighted and threw the first. It went wide, and the Roller started a quick retreat, pulling the catapult after him. But Carson had the others ready and threw them in rapid succession. The fourth wedged in the catapult's framework and did the trick. The Roller tried desperately to put out the spreading blaze by throwing sand, but its clawed tentacles would take only a spoonful at a time and its efforts were ineffectual. The catapult burned.

  The Roller moved safely away from the fire and seemed to concentrate its attention on Carson. Again he felt that wave of hatred and nausea — but more weakly; either the Roller itself was weakening or Carson had learned how to protect himself against the mental attack.
