he thought it had probably drawn the same deduction about the nature of the barrier that he had drawn. But it would come cautiously. He would have a little time—
He struck.
Pain brought him back to consciousness. A sudden, sharp pain in his hip that was different from the throbbing pain in his head and the throbbing pain in his leg.
But he had, thinking things out before he had struck himself, anticipated that very pain, even hoped for it, and had steeled himself against awakening with a sudden movement.
He lay still, but opened his eyes just a slit, and saw that he had guessed rightly.
The Roller was coming closer. It was twenty feet away and the pain that had awakened him was the stone it had tossed to see whether he was alive or dead.
He lay still. It came closer, fifteen feet away, and stopped again. Carson scarcely breathed.
As nearly as possible, he was keeping his mind a blank, lest its telepathic ability detect consciousness in him. And with his mind blanked out that way, the impact of its thoughts upon his mind was nearly soul- shattering.
He felt sheer horror at the utter alienness, the differentness of those thoughts.
Things that he felt but could not understand and could never express, because no terrestrial language had words, no terrestrial mind had images to fit them. The mind of a spider, he thought, or the mind of a praying mantis or a Martian sand-serpent, raised to intelligence and put in telepathic rapport with human minds, would be a homely familiar thing, compared to this.
He understood now that the Entity had been right: Man or Roller, and the universe was not a place that could hold them both. Farther apart than god and devil, there could never be even a balance between them.
Closer. Carson waited until it was only feet away, until its clawed tentacles reached out—
Oblivious to agony now, he sat up, raised and flung the harpoon with all the strength that remained to him. Or he thought it was all; sudden final strength flooded through him, along with a sudden forgetfulness of pain as definite as a nerve block.
As the Roller, deeply stabbed by the harpoon, rolled away, Carson tried to get to his feet to run after it. He couldn't do that; he fell, but kept crawling.
It reached the end of the rope, and he was jerked forward by the pull of his wrist.
It dragged him a few feet and then stopped. Carson kept on going, pulling himself toward it hand over hand along the rope.
It stopped there, writhing tentacles trying in vain to pull out the harpoon. It seemed to shudder and quiver, and then it must have realized that it couldn't get away, for it rolled back toward him, clawed tentacles reaching out.
Stone knife in hand, he met it. He stabbed, again and again, while those horrid claws ripped skin and flesh and muscle from his body.
He stabbed and slashed, and at last it was still.
A bell was ringing, and it took him a while after he'd opened his eyes to tell where he was and what it was. He was strapped into the seat of his scouter, and the visiplate before him showed only empty space. No Outsider ship and no impossible planet.
The bell was the communications plate signal; someone wanted him to switch power into the receiver. Purely reflex action enabled him to reach forward and throw the lever.
The face of Brander, captain of the Magellan, mother-ship of his group of scouters, flashed into the screen. His face was pale and his black eyes glowed with excitement.
'Magellan to Carson,' he snapped. 'Come on in. The fight's over. We've won!'
The screen went blank; Brander would be signaling the other scouters of his command.
Slowly, Carson set the controls for the return. Slowly, unbelievingly, he unstrapped himself from the seat and went back to get a drink at the cold-water tank.
For some reason, he was unbelievably thirsty. He drank six glasses.
He leaned there against the wall, trying to think.
Had it happened? He was in good health, sound, uninjured. His thirst had been mental rather than physical; his throat hadn't been dry. His leg- He pulled up his trouser leg and looked at the calf. There was a long white scar there, but a perfectly healed scar. It hadn't been there before. He zipped open the front of his shirt and saw that his chest and abdomen was criss-crossed with tiny, almost unnoticeable, perfectly healed scars.
It had happened.
The scouter, under automatic control, was already entering the hatch of the mother-ship. The grapples pulled it into its individual lock, and a moment later a buzzer indicated that the lock was air-filled. Carson opened the hatch and stepped outside, went through the double door of the lock.
He went right to Brander's office, went in, and saluted.
Brander still looked dizzily dazed. 'Hi, Carson,' he said. 'What you missed! What a show!'
'What happened, sir?'
'Don't know, exactly. We fired one salvo, and their whole fleet went up in dust!
Whatever it was jumped from ship to ship in a flash, even the ones we hadn't aimed at and that were out of range! The whole fleet disintegrated before our eyes, and we didn't get the paint of a single ship scratched!
'We can't even claim credit for it. Must have been some unstable component in the metal they used, and our sighting shot just set it off. Man, oh man, too bad you missed all the excitement.'
Carson managed to grin. It was a sickly ghost of a grin, for it would be days before he'd be over the mental impact of his experience, but the captain wasn't watching, and didn't notice.
'Yes, sir,' he said. Common sense, more than modesty, told him he'd be branded forever as the worst liar in space if he ever said any more than that. 'Yes, sir, too bad I missed all the excitement.'
Tommy Don went into the captain's room with his last pair of stereo- photos and said:
'I'm through, sir. These are the last two pictures I can take.'
He handed over the photographs and looked with professional interest at the visiplates which showed all space outside the ship. Subdued, deep- red lighting indicated the controls and such instruments as the quartermaster on duty needed for navigation of the spaceship Llanvabon. There was a deeply cushioned control chair.
There was the little gadget of oddly angled mirrors—remote descendant of the back-view mirrors of twentieth-century motorists—which allowed a view of all the visiplates without turning the head. And there were the huge plates which were so much more satisfactory for a direct view of space.
The Llanvabon was a long way from home. The plates, which showed every star of visual magnitude and could be stepped up to any desired magnification, portrayed stars of every imaginable degree of brilliance, in the startlingly different colors they show outside of atmosphere. But every one was unfamiliar. Only two constellations could be recognized as seen from Earth, and they were shrunken and distorted. The Milky Way seemed vaguely out of place. But even such oddities were minor compared to a sight in the forward plates.
There was a vast, vast mistiness ahead. A luminous mist. It seemed motionless. It took a long time for any appreciable nearing to appear in the vision plates, though the spaceship's velocity indicator showed an incredible speed. The mist was the Crab Nebula, six light-years long, three and a half light-years thick, and outward-reaching members that in the telescopes of Earth gave it some resemblance to the creature for which it was named. It was a cloud of gas, infinitely tenuous, reaching half again as far as from Sol to its nearest neighbor-sun. Deep within it burned two stars; a double star; one component the familiar yellow of the sun of Earth, the other an unholy white.
Tommy Dort said meditatively:
'We're heading into a deep, sir?'
The skipper studied the last two plates of Tommy's taking, and put them aside. He went back to his uneasy contemplation of the vision plates ahead. The Llanvabon was decelerating at full force. She was a bare half light-
