Minutes passed before Foscar's arm raised in a wave to summon the party guarding Ross. Ennar kicked his horse to a trot, towing Ross's mount behind, the other two men thudding along more discreetly. Ross noted that they were both armed with spears which they carried to the fore as they rode.

  They were perhaps three quarters of the way to join Foscar, and Ross could see plainly the bald heads of the aliens as their faces turned in his direction. Then the strangers struck. One of them raised a weapon shaped similarly to the automatic Ross knew, except that it was longer in the barrel.

  Ross did not know why he cried out, except that Foscar had only an ax and dagger which were both still sheathed at his belt. The chief sat very still, and then his horse gave a swift sidewise swerve as if in fright. Foscar collapsed, limp, bonelessly, to the trodden turf, to lie unmoving face down.

  Ennar whooped, a cry combining defiance and despair in one. He reined up with violence enough to set his horse rearing. Then, dropping his hold on the leading rope of Ross's mount, he whirled and set off in a wild dash for the trees to the left. A spear lanced across Ross's shoulder, ripping at the blue fabric, but his horse whirled to follow the other, taking him out of danger of a second thrust. Having lost his opportunity, the man who had wielded the spear dashed by at Ennar's back.

  Ross clung to the mane with both hands. His greatest fear was that he might slip from the saddle pad and since he was tied by his feet, lie unprotected and helpless under those dashing hoofs. Somehow he managed to cling to the horse's neck, his face lashed by the rough mane while the animal pounded on. Had Ross been able to grasp the dangling nose rope, he might have had a faint chance of controlling that run, but as it was he could only hold fast and hope.

  He had only broken glimpses of what lay ahead. Then a brilliant fire, as vivid as the flames which had eaten up the Red village, burst from the ground a few yards ahead, sending the horse wild. There was more fire and the horse changed course through the rising smoke. Ross realized that the aliens were trying to cut him off from the thin safety of the woodlands. Why they didn't just shoot him as they had Foscar he could not understand.

  The smoke of the burning grass was thick, cutting between him and the woods. Might it also provide a curtain behind which he could hope to escape both parties? The fire was sending the horse back toward the waiting ship people. Ross could hear a confused shouting in the smoke. Then his mount made a miscalculation, and a tongue of red licked too close. The animal screamed, dashing on blindly straight between two of the blazes and away from the blue-clad men.

  Ross coughed, almost choking, his eyes watering as the stench of singed hair thickened the smoke. But he had been carried out of the fire circle and was shooting back into the meadowland. Mount and unwilling rider were well away from the upper end of that cleared space when another horse cut in from the left, matching speed to the uncontrolled animal to which Ross clung. It was one of the tribesmen riding easily.

  The trick worked, for the wild race slowed to a gallop and the other rider, in a feat of horsemanship at which Ross marveled, leaned from his seat to catch the dangling nose rope, bringing the runaway against his own steady steed. Ross shaken, still coughing from the smoke and unable to sit upright, held to the mane. The gallop slowed to a rocking pace and finally came to a halt, both horses blowing, white-foam patches on their chests and their riders' legs.

  Having made his capture, the tribesman seemed indifferent to Ross, looking back instead at the wide curtain of grass smoke, frowning as he studied the swift spread of the fire. Muttering to himself, he pulled the lead rope and brought Ross's horse to follow in the direction from which Ennar had brought the captive less than a half hour earlier.

  Ross tried to think. The unexpected death of their chief might well mean his own, should the tribe's desire for vengeance now be aroused. On the other hand, there was a faint chance that he could now better impress them with the thought that he was indeed of another clan and that to aid him would be to work against a common enemy.

  But it was hard to plan clearly, though wits alone could save him now. The parley which had ended with Foscar's murder had brought Ross a small measure of time. He was still a captive, even though of the tribesmen and not the unearthly strangers. Perhaps to the ship people these primitives were hardly higher in scale than the forest animals.

  Ross did not try to talk to his present guard, who towed him into the western sun of late afternoon. They halted at last in that same small grove where they had rested at noon. The tribesman fastened the mounts and then walked around to inspect the animal Ross had ridden. With a grunt he loosened the prisoner and spilled him unceremoniously on the ground while he examined the horse. Ross levered himself up to sight the mark of the burn across that roan hide where the fire had blistered the skin.

  Thick handfuls of mud from the side of the spring were brought and plastered over the seared strip. Then, having rubbed down both animals with twists of grass, the man came over to Ross, pushed him back to the ground, and studied his left leg.

  Ross understood. By rights, his thigh should also have been scorched where the flame had hit, yet he had felt no pain. Now as the tribesman examined him for a burn, he could not see even the faintest discoloration of the strange fabric. He remembered how the aliens had strolled unconcerned through the burning village. As the suit had insulated him against the cold of the ice, so it would seem that it had also protected him against the fire, for which he was duly thankful. His escape from injury was a puzzle to the tribesman, who, failing to find any trace of burn on him, left Ross alone and went to sit well away from his prisoner as if he feared him.

  They did not have long to wait. One by one, those who had ridden in Foscar's company gathered at the grove. The very last to come were Ennar and Tulka, carrying the body of their chief. The faces of both men were smeared with dust and when the others sighted the body they, too, rubbed dust into their cheeks, reciting a string of words and going one by one to touch the dead chieftain's right hand.

  Ennar, resigning his burden to the others, slid from his tired horse and stood for a long moment, his head bowed. Then he gazed straight at Ross and came across the tiny clearing to stand over the man of a later time. The boyishness which had been a part of him when he had fought at Foscar's command was gone. His eyes were merciless as he leaned down to speak, shaping each word with slow care so that Ross could understand the promise—that frightful promise:

  "Woods rat, Foscar goes to his burial fire. And he shall take a slave with him to serve him beyond the sky—a slave to run at his voice, to shake when he thunders. Slave-dog, you shall run for Foscar beyond the sky, and he shall have you forever to walk upon as a man walks upon the earth. I, Ennar, swear that Foscar shall be sent to the chiefs in the sky in all honor. And that you, dog-one, shall lie at his feet in that going!"

  He did not touch Ross, but there was no doubt in Ross's mind that he meant every word he spoke.

  CHAPTER 17

  The preparations for Foscar's funeral went on through the night. A wooden structure, made up of tied fagots dragged in from the woodland, grew taller beyond the big tribal camp. The constant crooning wail of the women in the tents produced a minor murmur of sound, enough to drive a man to the edge of madness. Ross had been left under guard where he could watch it all, a refinement of torture which he would earlier have believed too subtle for Ennar. Though the older men carried minor commands among the horsemen, because Ennar was the closest of blood kin among the adult males, he was in charge of the coming ceremony.

  The pick of the horse herd, a roan stallion, was brought in to be picketed near Ross as sacrifice number two, and two of the hounds were in turn leashed close by. Foscar, his best weapons to hand and a red cloak lapped about him, lay waiting on a bier. Near-by squatted the tribal wizard, shaking his thunder rattle and chanting in a voice which approached a shriek. This wild activity might have been a scene lifted directly from some tape stored at the project base. It was very difficult for Ross
to remember that this was reality, that he was to be one of the main actors in the coming event, with no timely aid from Operation Retrograde to snatch him to safety.

  Sometime during that nightmare he slept, his weariness of body overcoming him. He awoke, dazed, to find a hand clutching his mop of hair, pulling his head up.

  "You sleep—you do not fear, Foscar's dog-one?"

  Groggily Ross blinked up. Fear? Sure, he was afraid. Fear, he realized with a clear thrust of consciousness such as he had seldom experienced before, had always stalked beside him, slept in his bed. But he had never surrendered to it, and he would not now if he could help it.

  "I do not fear!" He threw that creed into Ennar's face in one hot boast. He would not fear!

  "We shall see if you speak so loudly when the fire bites you!" The other spat, yet in that oath there was a reluctant recognition of Ross's courage.

  "When the fire bites...." That sang in Ross's head. There was something else—if he could only remember! Up to that moment he had kept a poor little shadow of hope. It is always impossible—he was conscious again with that strange clarity of mind—for a man to face his own death honestly. A man always continues to believe to the last moment of his life that something will intervene to save him.

  The men led the horse to the mound of fagots which was now crowned with Foscar's bier. The stallion went quietly, until a tall tribesman struck true with an ax, and the animal fell. The hounds were also killed and laid at their dead master's feet.

  But Ross was not to fare so easily. The wizard danced about him, a hideous figure in a beast mask, a curled fringe of dried snakeskins swaying from his belt. Shaking his rattle, he squawked like an angry cat as they pulled Ross to the stacked wood.

  Fire—there was something about fire—if he could only remember! Ross stumbled and nearly fell across one leg of the dead horse they were propping into place. Then he remembered that tongue of flame in the meadow grass which had burned the horse but not the rider. His hands and his head would have no protection, but the rest of his body was covered with the flame-resistant fabric of the alien suit. Could he do it? There was such a slight chance, and they were already pushing him onto that mound, his hands tied. Ennar stooped, and bound his ankles, securing him to the brush.

  So fastened, they left him. The tribe ringed around the pyre at a safe distance, Ennar and five other men approaching from different directions, torches aflame. Ross watched those blazing knots thrust into the brush and heard the crackle of the fire. His eyes, hard and measuring, studied the flash of flame from dried brush to seasoned wood.

  A tongue of yellow-red flame licked up at him. Ross hardly dared to breathe as it wreathed about his foot, his hide fetters smoldering. The insulation of the suit did not cut all the heat, but it allowed him to stay put for the few seconds he needed to make his escape spectacular.

  The flame had eaten through his foot bonds, and yet the burning sensation on his feet and legs was no greater than it would have been from the direct rays of a bright summer sun. Ross moistened his lips with his tongue. The impact of heat on his hands and his face was different. He leaned down, held his wrists to the flame, taking in stoical silence the burns which freed him.

  Then, as the fire curled up so that he seemed to stand in a frame of writhing red banners, Ross leaped through that curtain, protecting his bowed head with his arms as best he could. But to the onlookers it seemed he passed unhurt through the heart of a roaring fire.

  He kept his footing and stood facing that part of the tribal ring directly before him. He heard a cry, perhaps of fear, and a blazing torch flew through the air and struck his hip. Although he felt the force of the blow, the burning bits of the head merely slid down his thigh and leg, leaving no mark on the smooth blue fabric.

  "Ahhhhhhh!"

  Now the wizard capered before him, shaking his rattle to make a deafening din. Ross struck out, slapping the sorcerer out of his path, and stooped to pick up the smoldering brand which had been thrown at him. Whirling it about his head, though every movement was torture to his scorched hands, he set it flaming once more. Holding it in front of him as a weapon, he stalked directly at the men and women before him.

  The torch was a poor enough defense against spears and axes, but Ross did not care—he put into this last gamble all the determination he could summon. Nor did he realize what a figure he presented to the tribesmen. A man who had crossed a curtain of fire without apparent hurt, who appeared to wash in tongues of flame without harm, and who now called upon fire in turn as a weapon, was no man but a demon!

  The wall of people wavered and broke. Women screamed and ran; men shouted. But no one threw a spear or struck with an ax. Ross walked on, a man possessed, looking neither to the right or left. He was in the camp now, stalking toward the fire burning before Foscar's tent. He did not turn aside for that either, but holding the torch high, strode through the heart of the flames, risking further burns for the sake of insuring his ultimate safety.

  The tribesmen melted away as he approached the last line of tents, with the open land beyond. The horses of the herd, which had been driven to this side to avoid the funeral pyre, were shifting nervously, the scent of burning making them uneasy.

  Once more Ross whirled the dying torch about his head. Recalling how the aliens had sent his horse mad, he tossed it behind him into the grass between the tents and the herd. The tinder-dry stuff caught immediately. Now if the men tried to ride after him, they would have trouble.

  Without hindrance he walked across the meadow at the same even pace, never turning to look behind. His hands were two separate worlds of smarting pain; his hair and eyebrows were singed, and a finger of burn ran along the angle of his jaw. But he was free, and he did not believe that Foscar's men would be in any haste to pursue him. Somewhere before him lay the river, the river which ran to the sea. Ross walked on in the sunny morning while behind him black smoke raised a dark beacon to the sky.

  Afterward he guessed that he must have been lightheaded for several days, remembering little save the pain in his hands and the fact that it was necessary to keep moving. Once he fell to his knees and buried both hands in the cool, moist earth where a thread of stream trickled from a pool. The muck seemed to draw out a little of the agony while he drank with a fever thirst.

  Ross seemed to move through a haze which lifted at intervals during which he noted his surroundings, was able to recall a little of what lay behind him, and to keep to the correct route. However, the gaps of time in between were forever lost to him. He stumbled along the banks of a river and fronted a bear fishing. The massive beast rose on its hind legs, growled, and Ross walked by it uncaring, unmenaced by the puzzled animal.

  Sometimes he slept through the dark periods which marked the nights, or he stumbled along under the moon, nursing his hands against his breast, whimpering a little when his foot slipped and the jar of that mishap ran through his body. Once he heard singing, only to realize that it was himself who sang hoarsely a melody which would be popular thousands of years later in the world through which he wavered. But always Ross knew that he must go on, using that thick stream of running water as a guide to his final goal, the sea.

  After a long while those spaces of mental clarity grew longer, appearing closer together. He dug small shelled things from under stones along the river and ate them avidly. Once he clubbed a rabbit and feasted. He sucked birds' eggs from a nest hidden among some reeds—just enough to keep his gaunt body going, though his gray eyes were now set in what was almost a death's-head.

  Ross did not know just when he realized that he was again being hunted. It started with an uneasiness which differed from his previous fever-bred hallucinations. This was an inner pulling, a growing compulsion to turn and retrace his way back toward the mountains to meet something, or someone, waiting for him on the backward path.

  But Ross kept on, fearing sleep now and fighting it. For once he had lain down to rest and had wakened on his feet, heading back as if that compul
sion had the power to take over his body when his waking will was off guard.

  So he rested, but he dared not sleep, the desire constantly tearing at his will, striving to take over his weakened body and draw it back. Perhaps against all reason he believed that it was the aliens who were trying to control him. Ross did not even venture to guess why they were so determined to get him. If there were tribesmen on his trail as well, he did not know, but he was sure that this was now purely a war of wills.

  As the banks of the river were giving way to marshes, he had to wade through mud and water, detouring the boggy sections. Great clouds of birds whirled and shrieked their protests at his coming, and sleek water animals paddled and poked curious heads out of the water as this two-legged thing walked mechanically through their green land. Always that pull was with him, until Ross was more aware of fighting it than of traveling.

  Why did they want him to return? Why did they not follow him? Or were they afraid to venture too far from where they had come through the transfer? Yet the unseen rope which was tugging at him did not grow less tenuous as he put more distance between himself and the mountain valley. Ross could understand neither their motives nor their methods, but he could continue to fight.

  The bog was endless. He found an island and lashed himself with his suit belt to the single willow which grew there, knowing that he must have sleep, or he could not hope to last through the next day. Then he slept, only to waken cold, shaking, and afraid. Shoulder deep in a pool, he was aware that in his sleep he must have opened the belt buckle and freed himself, and only the mishap of falling into the water had brought him around to sanity.

  Somehow he got back to the tree, rehooked the buckle and twisted the belt around the branches so that he was sure he could not work it free until daybreak. He lapsed into a deepening doze, and awoke, still safely anchored, with the morning cries of the birds. Ross considered the suit as he untangled the belt. Could the strange clothing be the tie by which the aliens held to him? If he were to strip, leaving the garment behind, would he be safe?
