They set their ambush with the age-old skill the Redax had grafted into their memories. Then there was nothing to do but wait.

It was an hour after dawn when Tsoay signaled that the enemy was coming, and shortly after, they heard the thud of ponies' hoofs. The first Tatar plodded into view, and by the stance of his body in the saddle, Travis knew the Red had him under full control. Two, then three Tatars passed between the teeth of the Apache trap. The fourth one had allowed a wider gap to open between himself and his fellows.

Then the Red leader came. His face below the bulge of the helmet was not happy. Travis believed the man was not a horseman by inclination. The Apache set arrow to bow cord, and at the chirp from Nolan, fired in concert with his clansmen.

Only one of those arrows found a target. The Red's pony gave a shrill scream of pain and terror, reared, pawing at the air, toppled back, pinning its shouting rider under it.

The Red had had a defense right enough, one which had somehow deflected the arrows. But he neither had protection against his own awkward seat in the saddle nor the arrow which had seriously wounded the now threshing pony.

Ahead the Tatars twisted and writhed, mouthed tortured cries, then dropped out of their saddles to lie limply on the ground as if the arrows aimed at the master had instead struck each to the heart.

Either the Red was lucky, or his reactions were quick. He had somehow rolled clear of the struggling horse as Lupe leaped from behind a boulder, knife out and ready. To the eyes of the Apaches the helmeted man lay easy prey to Lupe's attack. Nor did he raise an arm to defend himself, though one hand lay free across the plate on his chest.

But the young Apache stumbled, rebounding back as if he had run into an unseen wall—when his knife was still six inches away from the other. Lupe cried out, shook under a second impact as the Red fired an automatic with his other hand.

Travis dropped his bow, returned to the most primitive weapon of all. His hand closed around a stone and he hurled the fist-sized oval straight at the helmet so clearly outlined against the rocks below.

But even as Lupe's knife had never touched flesh, so was the rock deflected; the Red was covered by some protective field. This was certainly nothing the Apaches had seen before. Nolan's whistle summoned them to draw back.

The Red fired again, the sharp bark of the hand gun harsh and loud. He did not have any real target, for with the exception of Lupe the Apaches had gone to earth. Between the rocks the Red was struggling to his feet, but he moved slowly, favoring his side and one leg; he had not come totally unharmed from his tumble with the pony.

An armed enemy who could not be touched—one who knew there were more than outlaws in this region. The Red leader was far more of a threat to the Apaches now than he had ever been. He must not be allowed to escape.

He was holstering his gun, moving along with one hand against the rocks to steady himself, trying to reach one of the ponies that stood with trailing reins beside the inert Tatars.

But when the enemy reached the far side of that rock he would have to sacrifice either his steadying hold, or his touch on the chest plate where his other hand rested. Would he, then, for an instant be vulnerable?

The pony!

Travis put an arrow on bow cord and shot. Not at the Red, who had released his hold of the rock, preferring to totter instead of lose control of the chest plate—but into the air straight before the nose of the mount.

The pony neighed wildly, tried to turn, and its shoulder caught the free, groping hand of the Red and spun the man around and back, so that he flung up both hands in an effort to ward himself off the rocks. Then the pony stampeded down the break, its companions catching the same fever, trailing in a mad dash which kept the Red hard against the boulders.

He continued to stand there until the horses, save for the wounded one still kicking fruitlessly, were gone. Travis felt a sense of reprieve. They might not be able to get at the Red, but he was hurt and afoot, two strikes which might yet reduce him to a condition the Apaches could handle.

Apparently the other was also aware of that, for now he pushed out from the rocks and stumbled along after the ponies. But he went only a step or two. Then, settling back once more against a convenient boulder, he began to work at the plate on his chest.

Nolan appeared noiselessly beside Travis. "What does he do?" His lips were very close to the younger man's ear, his voice hardly more than a breath.

Travis shook his head slightly. The Red's actions were a complete mystery. Unless, now disabled and afoot, he was trying to summon aid. Though there was no landing place for a helicopter here.

Now was the time to try and reach Lupe. Travis had seen a slight movement in the fallen Apache's hand, the first indication that the enemy's shot had not been as fatal as it had looked. He touched Nolan's arm, pointed to Lupe; and then, discarding his bow and quiver beside the war leader, he stripped for action. There was cover down to the wounded Apache which would aid him. He must pass one of the Tatars on the way, but none of the tribesmen had shown any signs of life since they had fallen from their saddles at the first attack.

With infinite care, Travis lowered himself into a narrow passage, took a lizard's way between brush and boulder, pausing only when he reached the Tatar for a quick check on the potential enemy.

The lean brown face was half turned, one cheek in the sand, but the slack mouth, the closed eyes were those, Travis believed, of a dead man. By some action of his diabolic machine the Red must have snuffed out his four captives—perhaps in the belief that they were part of the Apache attack.

Travis reached the rock where Lupe lay. He knew that Nolan was watching the Red and would give him warning if he suddenly showed an interest in anything but his machine. The Apache reached out, his hands closing on Lupe's ankles. Beneath his touch, flesh and muscle tensed. Lupe's eyes were open, focused now on Travis. There was a bleeding furrow above his right ear. The Red had tried a difficult head shot, failing in his aim by a mere fraction of an inch.

Lupe made a swift move for which Travis was ready. His grip on the other's body helped to tumble them both around a rock which lay between them and the Red. There was the crack of another shot and dust spurted from the side of the boulder. But they lay together, safe for the present, as Travis was sure the enemy would not risk an open attack on their small fortress.

With Travis' aid Lupe struggled back up to the site where Nolan waited. Jil-Lee was there to make competent examination of the boy's wound.

"Creased," he reported. "A sore head, but no great damage. Perhaps a scar later, warrior!" He gave Lupe an encouraging thump on the shoulder, before plastering an aid pack over the cut.

"Now we go!" Nolan spoke with emphatic decision.

"He saw enough of us to know we are not Tatars."

Nolan's eyes were cold, his mouth grim as he faced Travis.

"And how can we fight him—?"

"There is a wall—a wall you cannot see—about him," Lupe broke in. "When I would strike at him, I could not!"

"A man with invisible protection and a gun," Jil-Lee took up the argument. "How would you deal with him, younger brother?"

"I don't know," Travis admitted. Yet he also believed that if they withdrew, left the Red here to be found by his own people, the enemy would immediately begin an investigation of the southern country. Perhaps, pushed by their need for learning more about the Apaches, they would bring the helicopter in over the mountains. The answer to all Apache dangers, for now, lay in the immediate future of this one man.

"He is hurt, he cannot go far on foot. And even if he calls the 'copter, there is no landing place. He will have to move elsewhere to be picked up." Travis thought aloud, citing the thin handful of points in their favor.

Tsoay nodded toward the rim of the ravine. "Rocks up there and rocks can roll. Start an earthslide...."

Something within Travis balked at that. From the first he had been willing enough to slug it out with the Red, weapon to weapon, man to man. Also, he had wanted to take a captive, not stand over a body. But to use the nature of the country against the enemy, that was the oldest Apache trick of all and one they would have to be forced to employ.

Nolan had already nodded in assent, and Tsoay and Jil-Lee started off. Even if the Red did possess a protective wall device, could it operate in full against a landslide? They all doubted that.

The Apaches reached the cliff rim without exposing themselves to the enemy's fire. The Red still sat there calmly, his back against the rock, his hands busy with his equipment as if he had all the time in the world.

Then suddenly came a scream from more than one throat.

"Dar-u-gar!" The ancient war cry of the Mongol Hordes.

Then over the lip of the other slope rose a wave of men—their curved swords out, a glazed set to their eyes—heading for the Amerindians with utter disregard for any personal safety. Menlik in the lead, his shaman's robe flapping wide below his belt like the wings of some oversized predatory bird. Hulagur ... Jagatai ... men from the outlaws' camp. And they were not striving to destroy their disabled overlord in the vale below, but to wipe out the Apaches!

Only the fact that the Apaches were already sheltered behind the rocks they were laboring to dislodge gave them a precious few moments of grace. There was no time to use their bows. They could only use knives to meet the swords of the Tatars, knives and the fact that they could fight with unclouded minds.

"He has them under control!" Travis pawed at Jil-Lee's shoulder. "Get him—they'll stop!"

He did not wait to see if the other Apache understood. Instead, he threw the full force of his own body against the rock they had made the center stone of their slide. It gave, rolled, carrying with it and before it the rest of the piled rubble. Travis stumbled, fell flat, and then a body thudded down upon him, and he was fighting for his life to keep a blade from his throat. Around him were the shouts and cries of embroiled warriors; then all was silenced by a roar from below.

Glazed eyes in a face only a foot from his own, the twisted, panting mouth sending gusts of breath into his nostrils. Suddenly there was reason back in those eyes, a bewilderment, which became fear ... panic.... The Tatar's body twisted in Travis' hold, striving now not to attack, but to win free. As the Apache loosened his grip the other jerked away, so that for a moment or two they lay gasping, side by side.

Men sat up to look at men. There was a spreading stain down Jil-Lee's side and one of the Tatars sprawled near him, both his hands on his chest, coughing violently.

Menlik clawed at the trunk of a wind-twisted mountain tree, pulled himself to his feet, and stood swaying as might a man long ill and recovering from severe exertion.

Insensibly both sides drew apart, leaving a space between Tatar and Apache. The faces of the Amerindians were grim, those of the Mongols bewildered and then harsh as they eyed their late opponents with dawning reason. What had begun in compulsion for the Tatars might well flare now into rational combat—and from that to a campaign of extermination.

Travis was on his feet. He looked over the lip of the drop. The Red was still in his place down there, a pile of rubble about him. His protection must have failed, for his head was back at an unnatural angle and the dent in his helmet could be easily seen.

"That one is dead—or helpless!" Travis cried out. "Do you still wish to fight for him, Shaman?"

Menlik came away from the tree and walked to the edge of the drop. The others, too, were moving forward. After the shaman looked down he stooped, picked up a small stone, and flung it at the motionless Red. There was a crack of sound. They all saw the tiny spurt of flame, a curl of smoke from the plate on the Red's chest. Not only the man, but his control was finished now.

A wolfish growl and two of the Tatars swung over, started down to the Red. Menlik shouted and they slackened pace.

"We want that," he cried in English. "Perhaps so we can learn—"

"The learning is yours," Jil-Lee replied. "Just as this land is yours, Shaman. But I warn you, from this day do not ride south!"

Menlik turned, the charms on his belt clicking. "So that is the way it is to be, Apache?"

"That is the way it shall be, Tatar! We do not ride to war with allies who may turn their knives against our backs because they are slaves to a machine the enemy controls."

The Tatar's long, slender-fingered hands opened and closed. "You are a wise man, Apache, but sometimes more than wisdom alone is needed——"

"We are wise men, Shaman, let it rest there," Jil-Lee replied somberly.

Already the Apaches were on their way, putting two cliff ridges behind them before they halted to examine and cover their wounds.

"We go." Nolan's chin lifted, indicating the southern route. "Here we do not come again; there is too much witchcraft in this place."

Travis stirred, saw that Jil-Lee was frowning at him.

"Go—?" he repeated.

"Yes, younger brother? You would continue to run with these who are governed by a machine?"

"No. Only, eyes are needed on this side of the mountains."

"Why?" This time Jil-Lee was plainly on the side of the conservatives. "We have now seen this machine at work. It is fortunate that the Red is dead. He will carry no tales of us back to his people as you feared. Thus, if we remain south from now on, we are safe. And this fight between Tatar and Red is none of ours. What do you seek here?"

"I must go again to the place of the towers," Travis answered with the truth. But his friends were facing him with heavy disapproval—now a full row of Deklays.

"Did you not tell us that you felt this strange thing during the night we waited about the camp? What if you become one with these Tatars and are also controlled by the machine? Then you, too, can be made into a weapon against us—your clansmen!" Jil-Lee was almost openly hostile.

Sense was on his side. But in Travis was this other desire of which he was becoming more conscious by the minute. There was a reason for those towers, perhaps a reason important enough for him to discover and run the risk of angering his own people.

"There may be this—" Nolan's voice was remote and cold, "you may already be a piece of this thing, bound to the machines. If so, we do not want you among us."

There it was—an open hostility with more power behind it than Deklay's motiveless disapproval had carried. Travis was troubled. The family, the clan—they were important. If he took the wrong step now and was outlawed from that tight fortress, then as an Apache he would indeed be a lost man. In the past of his people there had been renegades from the tribe—men such as the infamous Apache Kid who had killed and killed again, not only white men but his own people. Wolf men living wolves' lives in the hills. Travis was threatened with that. Yet—up the ladder of civilization, down the ladder—why did this feverish curiosity ride him so cruelly now?

"Listen," Jil-Lee, his side padded with bandages, stepped closer—"and tell me, younger brother, what is it that you seek in these towers?"

"On another world there were secrets of the old ones to be found in such ancient buildings. Here that might also be true."

"And among the secrets of those old ones," Nolan's voice was still harsh—"were those which brought us to this world, is that not so?"

"Did any man drive you, Nolan, or you, Tsoay, or you, Jil-Lee, or any of us, to promise to go beyond the stars? You were told what might be done, and you were eager to try it. You were all volunteers!"

"Save for this voyage when we were told nothing," Jil-Lee answered, cutting straight to the heart of the matter. "Yet, Nolan, I do not believe that it is for more voyage tapes that our younger brother now searches, nor would those do us any good—as our ship will not rise again from here. What is it that you do seek?"

"Knowledge—weapons, maybe. Can we stand against these machines of the Reds? Yet many of the devices they now use are taken from the star ships they have looted through time. To every weapon there is a defense."

Nolan blinked and for the first time a hint of interest touched the mask of his face. "To the bow, the rifle," he said softly, "to the rifle, the machine gun, to the cannon, the big bomb. The defense can be far worse than the first weapon. So you think that in these towers there may be things which shall be to the Reds' machines as the bomb is to the cannon of the Horse Soldiers?"

Travis had an inspiration. "Did not our people lay aside the bow for the rifle when we went up against the Bluecoats?"

"We do not so go up against these Reds!" protested Lupe.

"Not now. But what if they come across the mountains, perhaps driving the Tatars before them to do their fighting—?"

"And you believe that if you find weapons in these towers, you will know how to use them?" Jil-Lee asked. "What will give you that knowledge, younger brother?"

"I do not claim such knowledge," Travis countered. "But this much I do have: Once I studied to be an archaeologist and I have seen other storehouses of these star people. Who else among us can say as much as that?"

"That is the truth," Jil-Lee acknowledged. "Also there is good sense in this seeking out of the tower things. Let the Reds find such first—if they exist at all—and then we may truly be caught in a box canyon with only death at our heels."

"And you would go to these towers now?" Nolan demanded.

"I can cut across country and then rejoin you on the other side of the pass!" The feeling of urgency which had been mounting in Travis was now so demanding that he wanted to race ahead through the wilderness. He was surprised when Jil-Lee put out his palm up as if to warn the younger man.

"Take care, younger brother! This is not a lucky business. And remember, if one goes too far down a wrong trail, there is sometimes no returning—"

"We shall wait on the other side of the pass for one day," Nolan added. "Then—" he shrugged—"where you go will be your own affair."

Travis did not understand that promise of trouble. He was already two steps down his chosen path.



12

Travis had taken a direct cross route through the heights, but not swiftly enough to reach his objective before nightfall. And he had no wish to enter the tower valley by moonlight. In him two emotions now warred. There was the urge to invade the towers, to discover their secret, and flaring higher and higher the beginnings of a new fear. Was he now a battlefield for the superstitions of his race reborn by the Redax and his modern education in the Pinda-lick-o-yi world—half Apache brave of the past, half modern archaeologist with a thirst for knowledge? Or was the fear rooted more deeply and for another reason?

Travis crouched in a hollow, trying to understand what he felt. Why was it suddenly so overwhelmingly important for him to investigate the towers? If he only had the coyotes with him.... Why and where had they gone?

He was alive to every noise out of the night, every scent the wind carried to him. The night had its own life, just as the daylight hours held theirs. Only a few of those sounds could he identify, even less did he see. There was one wide-winged, huge flying thing which passed across the green-gold plate of the nearer moon. It was so large that for an instant Travis believed the helicopter had come. Then the wings flapped, breaking the glide, and the creature merged in the shadows of the night—a hunter large enough to be a serious threat, and one he had never seen before.

Relying on his own small defense, the strewing of brittle sticks along the only approach to the hollow, Travis dozed at intervals, his head down on his forearm across his bent knees. But the cold cramped him and he was glad to see the graying sky of pre-dawn. He swallowed two ration tablets and a couple of mouthfuls of water from his canteen and started on.

By sunup he had reached the ledge of the waterfall, and he hurried along the ancient road at a pace which increased to a run the closer he drew to the valley. Deliberately he slowed, his native caution now in control, so that he was walking as he passed through the gateway into the swirling mists which alternately exposed and veiled the towers.

There was no change in the scene from the time he had come there with Kaydessa. But now, rising from a comfortable sprawl on the yellow-and-green pavement, was a welcoming committee—Nalik'ideyu and Naginlta showing no more excitement at his coming than if they had parted only moments before.

Travis went down on one knee, holding out his hand to the female, who had always been the more friendly. She advanced a step or two, touched a cold nose to his knuckles, and whined.

"Why?" He voiced that one word, but behind it was a long list of questions. Why had they left him? Why were they here where there was no hunting? Why did they meet him now as if they had calmly expected his return?

Travis glanced from the animals to the towers, those windows set in diamond pattern. And again he was visited by the impression that he was under observation. With the mist floating across those openings, it would be easy for a lurker to watch him unseen.

He walked slowly on into the valley, his moccasins making no sound on the pavement, but he could hear the faint click of the coyotes' claws as they paced beside him, on each hand. The sun did not penetrate here, making merely a gilt fog of the mist. As he approached within touching distance of the first tower, it seemed to Travis that the mist was curling about him; he could no longer see the archway through which he had entered the valley.

"Naye'nezyani—Slayer of Monsters—give strength to the bow arm, to the knife wrist!" Out of what long-buried memory did that ancient plea come? Travis was hardly aware of the sense of the words until he spoke them aloud. "You who wait—shi inday to-dah ishan—an Apache is not food for you! I am Fox of the Itcatcudnde'yu—the Eagle People; and beside me walk ga'ns of power...."

Travis blinked and shook his head as one waking. Why had he spoken so, using words and phrases which were not part of any modern speech?

He moved on, around the base of the first tower, to find no door, no break in its surface below the second-story windows—to the next structure and the next, until he had encircled all three. If he were to enter any, he must find a way of reaching the lowest windows.

On he went to the other opening of the valley, the one which gave upon the territory of the Tatar camp. But he did not sight any of the Mongols as he hacked down a sapling, trimmed, and smoothed it into a blunt-pointed lance. His sash-belt, torn into even strips and knotted together, gave him a rope which he judged would be barely long enough for his purpose.

Then Travis made a chancy cast for the lower window of the nearest tower. On the second try the lance slipped in, and he gave a quick jerk, jamming the lance as a bar across the opening. It was a frail ladder but the best he could improvise. He climbed until the sill of the window was within reach and he could pull himself up and over.

The sill was a wide one, at least a twenty-four-inch span between the inner and outer surface of the tower. Travis sat there for a minute, reluctant to enter. Near the end of his dangling scarf-rope the two coyotes lay on the pavement, their heads up, their tongues lolling from their mouths, their expressions ones of detached interest.

Perhaps it was the width of the outer wall that subdued the amount of light in the room. The chamber was circular, and directly opposite him was a second window, the lowest of the matching diamond pattern. He took the four-foot drop from the sill to the floor but lingered in the light as he surveyed every inch of the room. There were no furnishings at all, but in the very center sank a well of darkness. A smooth pillar, glowing faintly, rose from its core. Travis' adjusting eyes noted how the light came in small ripples—green and purple, over a foundation shade of dark blue.

The pillar seemed rooted below and it extended up through a similar opening in the ceiling, providing the only possible exit up or down, save for climbing from window to window outside. Travis moved slowly to the well. Underfoot was a smooth surface overlaid with a velvet carpet of dust which arose in languid puffs as he walked. Here and there he sighted prints in the dust, strange triangular wedges which he thought might possibly have been made by the claws of birds. But there were no other footprints. This tower had been undisturbed for a long, long time.

He came to the well and looked down. There was dark there, dark in which the pulsations of light from the pillar shown the stronger. But that glow did not extend beyond the edge of the well through which the thick rod threaded. Even by close examination he could detect no break in the smooth surface of the pillar, nothing remotely resembling hand- or footholds. If it did serve the purpose of a staircase, there were no treads.

At last Travis put out his hand to touch the surface of the pillar. And then he jerked back—to no effect. There was no breaking contact between his fingers and an unknown material which had the sleekness of polished metal but—and the thought made him slightly queasy—the warmth and very slight give of flesh!

He summoned all his strength to pull free and could not. Not only did that hold grip him, but his other hand and arm were being drawn to join the first! Inside Travis primitive fears awoke full force, and he threw back his head, voicing a cry of panic as wild as that of a hunting beast.

An instant later, his left palm was as tight a prisoner as his right. And with both hands so held, his whole body was suddenly snapped forward, off the safe foundation of the floor, tight to the pillar.

In this position he was sucked down into the well. And while unable to free himself from the pillar, he did slip along its length easily enough. Travis shut his eyes in an involuntary protest against this weird form of capture, and a shiver ran through his body as he continued to descend.

After the first shock had subsided the Apache realized that he was not truly falling at all. Had the pillar been horizontal instead of vertical, he would have gauged its speed that of a walk. He passed through two more room enclosures; he must already be below the level of the valley floor outside. And he was still a prisoner of the pillar, now in total darkness.

His feet came down against a level surface, and he guessed he must have reached the end. Again he pulled back, arching his shoulders in a final desperate attempt at escape, and stumbled away as he was released.

He came up sideways against a wall and stood there panting. The light, which might have come from the pillar but which seemed more a part of the very air, was bright enough to reveal that he was in a corridor running into greater dark both right and left.

Travis took two strides back to the pillar, fitted his palms once again to its surface, with no result. This time his flesh did not adhere and there was no possible way for him to climb that slick pole. He could only hope that at some point the corridor would give him access to the surface. But which way to go—?

At last he chose the right-hand path and started along it, pausing every few steps to listen. But there was no sound except the soft pad of his own feet. The air was fresh enough, and he thought he could detect a faint current coming toward him from some point ahead—perhaps an exit.

Instead, he came into a room and a small gasp of astonishment was wrung out of him. The walls were blank, covered with the same ripples of blue-purple-green light which colored the pillar. Just before him was a table and behind it a bench, both carved from the native yellow-red mountain rock. And there was no exit except the doorway in which he now stood.

Travis walked to the bench. Immovable, it was placed so that whoever sat there must face the opposite wall of the chamber with the table before him. And on the table was an object Travis recognized immediately from his voyage in the alien star ship, one of the reader-viewers through which the involuntary explorers had learned what little they knew of the older galactic civilization.

A reader—and beside it a box of tapes. Travis touched the edge of that box gingerly, half expecting it to crumble into nothingness. This was a place long deserted. Stone table, bench, the towers could survive through centuries of abandonment, but these other objects....

The substance of the reader was firm under the film of dust; there was less dust here than had been in the upper tower chamber. Hardly knowing why, Travis threw one leg over the bench and sat down behind the table, the reader before him, the box of tapes just beyond his hand.

He surveyed the walls and then looked away hurriedly. The rippling colors caught at his eyes. He had a feeling that if he watched that ebb and flow too long, he would be captured in some subtle web of enchantment just as the Reds' machine had caught and held the Tatars. He turned his attention to the reader. It was, he believed, much like the one they had used on the ship.

This room, table, bench, had all been designed with a set purpose. And that purpose—Travis' fingers rested on the box of tapes he could not yet bring himself to open—that purpose was to use the reader, he would swear to that. Tapes so left must have had a great importance for those who left them. It was as if the whole valley was a trap to channel a stranger into this underground chamber.

Travis snapped open the box, fed the first disk into the reader, and applied his eyes to the vision tube at its apex.

The rippling walls looked just the same when he looked up once more, but the cramp in his muscles told Travis that time had passed—perhaps hours instead of minutes—since he had taken out the first disk. He cupped his hands over his eyes and tried to think clearly. There had been sheets of meaningless symbol writing, but also there had been many clear, three-dimensional pictures, accompanied by a singsong commentary in an alien tongue, seemingly voiced out of thin air. He had been stuffed with ragged bits and patches of information, to be connected only by guesses, and some wild guesses, too. But this much he did know—these towers had been built by the bald spacemen, and they were highly important to that vanished stellar civilization. The information in this room, as disjointed as it had been for him, led to a treasure trove on Topaz greater than he had dreamed.

Travis swayed on the bench. To know so much and yet so little! If Ashe were only here, or some other of the project technicians! A treasure such as Pandora's box had been, peril for one who opened it and did not understand. The Apache studied the three walls of blue-purple-green in turn and with new attention. There were ways through those walls; he was fairly sure he could unlock at least one of them. But not now—certainly not now!

And there was another thing he knew: The Reds must not find this. Such a discovery on their part would not only mean the end of his own people on Topaz, but the end of Terra as well. This could be a new and alien Black Death spread to destroy whole nations at a time!

If he could—much as his archaeologist's training would argue against it—he would blot out this whole valley above and below ground. But while the Reds might possess a means of such destruction, the Apaches did not. No, he and his people must prevent its discovery by the enemy by doing what he had seen as necessary from the first—wiping out the Red leaders! And that must be done before they chanced upon the towers!

Travis arose stiffly. His eyes ached, his head felt stuffed with pictures, hints, speculations. He wanted to get out, back into the open air where perhaps the clean winds of the heights would blow some of this frightening half knowledge from his benumbed mind. He lurched down the corridor, puzzled now by the problem of getting back to the window level.

Here, before him, was the pillar. Without hope, but still obeying some buried instinct, Travis again set his hands to its surface. There was a tug at his cramped arms; once more his body was sucked to the pillar. This time he was rising!

He held his breath past the first level and then relaxed. The principle of this weird form of transportation was entirely beyond his understanding, but as long as it worked in reverse he didn't care to find out. He reached the windowed chamber, but the sunlight had left it; instead, the clean cut of moon sweep lay on the dusty floor. He must have been hours in that underground place.

Travis pulled away from the embrace of the pillar. The bar of his wooden lance was still across the window and he ran for it. To catch the scouting party at the pass he must hurry. The report they would make to the clan now had to be changed radically in the face of his new discoveries. The Apaches dared not retreat southward and withdraw from the fight, leaving the Reds to use what treasure lay here.

As he hit the pavement below he looked about for the coyotes. Then he tried the mind call. But as mysteriously as they had met him in the valley, so now were they gone again. And Travis had no time to hunt for them. With a sigh, he began his race to the pass.

In the old days, Travis remembered, Apache warriors had been able to cover forty-five or fifty miles a day on foot and over rough territory. But perhaps his modern breeding had slowed him. He had been so sure he could catch up before the others were through the pass. But he stood now in the hollow where they had camped, read the sign of overturned stone and bent twig left for him, and knew they would reach the rancheria and report the decision Deklay and the others wanted before he could head them off.

Travis slogged on. He was so tired now that only the drug from the sustenance tablets he mouthed at intervals kept him going at a dogged pace, hardly more than a swift walk. And always his mind was haunted by fragments of pictures, pictures he had seen in the reader. The big bomb had been the nightmare of his own world for so long, and what was that against the forces the bald star rovers had been able to command?

He fell beside a stream and slept. There was sunshine about him as he arose to stagger on. What day was this? How long had he sat in the tower chamber? He was not sure of time any more. He only knew that he must reach the rancheria, tell his story, somehow win over Deklay and the other reactionaries to prove the necessity for invading the north in force.

A rocky point which was a familiar landmark came into focus. He padded on, his chest heaving, his breath whistling through parched, sun-cracked lips. He did not know that his face was now a mask of driven resolution.

"Hahhhhhh—"

The cry reached his dulled ears. Travis lifted his head, saw the men before him and tried to think what that show of weapons turned toward him could mean.

A stone thudded to earth only inches before his feet, to be followed by another. He wavered to a stop.

"Ni'ilgac—!"

Witch? Where was a witch? Travis shook his head. There was no witch.

"Do ne'ilka da'!"

The old death threat, but why—for whom?

Another stone, this one hitting him in the ribs with force enough to send him reeling back and down. He tried to get up again, saw Deklay grin widely and take aim—and at last Travis realized what was happening.

Then there was a bursting pain in his head and he was falling—falling into a well of black, this time with no pillar of blue to guide him.



13

The rasp of something wet and rough, persistent against his cheek; Travis tried to turn his head to avoid the contact and was answered by a burst of pain which trailed off into a giddiness, making him fear another move, no matter how minor. He opened his eyes and saw the pointed ears, the outline of a coyote head between him and a dull gray sky, was able to recognize Nalik'ideyu.

A wetness other than that from the coyote's tongue slid down his forehead now. The dull clouds overhead had released the first heavy rain Travis had experienced since their landing on Topaz. He shivered as the chill damp of his clothes made him aware that he must have been lying out in the full force of the downpour for some time.

It was a struggle to get to his knees, but Nalik'ideyu mouthed a hold on his shirt, tugging and pulling so that somehow he crept into a hollow beneath the branches of a tree where the spouting water was lessened to a few pattering drops.

There the Apache's strength deserted him again and he could only hunch over, his bent knees against his chest, trying to endure the throbbing misery in his head, the awful floating sensation which followed any movement. Fighting against that, he tried to remember just what had happened.

The meeting with Deklay and at least four or five others ... then the Apache accusation of witchcraft, a serious thing in the old days. Old days! To Deklay and his fellows, these were the old days! And the threat that Deklay or some other had shouted at him—"Do ne'ilka da'"—meant literally: "It won't dawn for you—death!"

Stones, the last thing Travis remembered were the stones. Slowly his hands went out to explore his body. There was more than one bruised area on his shoulders and ribs, even on his thighs. He must still have been a target after he had fallen under the stone which had knocked him unconscious. Stoned ... outlawed! But why? Surely Deklay's hostility could not have swept Buck, Jil-Lee, Tsoay, even Nolan, into agreeing to that? Now he could not think straight.

Travis became aware of warmth, not only of warmth and the soft touch of a furred body by his side, but a comforting communication of mind, a feeling he had no words to describe adequately. Nalik'ideyu was sitting crowded against him, her nose thrust up to rest on his shoulder. She breathed in soft puffs which stirred the loose locks of his rain-damp hair. And now he flung one arm about her, a gesture which brought a whisper of answering whine.

He was past wondering about the actions of the coyotes, only supremely thankful for Nalik'ideyu's present companionship. And a moment later when her mate squeezed under the low loop of a branch and joined them in this natural wickiup, Travis held out his other hand, drew it lovingly across Naginlta's wet hide.

"Now what?" he asked aloud. Deklay could only have taken such a drastic action with the majority of the clan solidly behind him. It could well be that this reactionary was the new chief, this act of Travis' expulsion merely adding to Deklay's growing prestige.

The shivering which had begun when Travis recovered consciousness, still shook him at intervals. Back on Terra, like all the others in the team, he had had every inoculation known to the space physicians, including several experimental ones. But the cold virus could still practically immobilize a man, and this was no time to give body room to chills and fever.

Catching his breath as his movements touched to life the pain in one bruise after another, Travis peeled off his soaked clothing, rubbed his body dry with handfuls of last year's leaves culled from the thick carpet under him, knowing there was nothing he could do until the whirling in his head disappeared. So he burrowed into the leaves until only his head was uncovered, and tried to sleep, the coyotes curling up one on either side of his nest.

He dreamed but later could not remember any incident from those dreams, save a certain frustration and fear. When he awoke, again to the sound of steady rain, it was dark. He reached out—both coyotes were gone. His head was clearer and suddenly he knew what must be done. As soon as his body was strong enough, he, too, would return to instincts and customs of the past. This situation was desperate enough for him to challenge Deklay.

In the dark Travis frowned. He was slightly taller, and three or four years younger than his enemy. But Deklay had the advantage in a stouter build and longer reach. However, Travis was sure that in his present life Deklay had never fought a duel—Apache fashion. And an Apache duel was not a meeting anyone entered into lightly. Travis had the right to enter the rancheria and deliver such a challenge. Then Deklay must meet him or admit himself in the wrong. That part of it was simple.

But in the past such duels had just one end, a fatal one for at least one of the fighters. If Travis took this trail, he must be prepared to go the limit. And he didn't want to kill Deklay! There were too few of them here on Topaz to make any loss less than a real catastrophe. While he had no liking for Deklay, neither did he nurse any hatred. However, he must challenge the other or remain a tribal outcast; and Travis had no right to gamble with time and the future, not after what he had learned in the tower. It might be his life and skill, or Deklay's, against the blotting out of them all—and their home world into the bargain.

First, he must locate the present camp of the clan. If Nolan's arguments had counted, they would be heading south away from the pass. And to follow would draw him farther from the tower valley. Travis' battered face ached as he grinned bitterly. This was another time when a man could wish he were two people, a scout on sentry duty at the valley, the fighter heading in the opposite direction to have it out with Deklay. But since he was merely one man he would have to gamble on time, one of the trickiest risks of all.

Before dawn Nalik'ideyu returned, carrying with her a bird—or at least birds must have been somewhere in the creature's ancestry, but the present representative of its kind had only vestigial remnants of wings, its trailing feet and legs well developed and far more powerful.

Travis skinned the corpse, automatically putting aside some spine quills to feather future arrows. Then he ate slivers of dusky meat raw, throwing the bones to Nalik'ideyu.

Though he was still stiff and sore, Travis was determined to be on his way. He tried mind contact with the coyote, picturing the Apaches, notably Deklay, as sharply as he could by mental image. And her assent was clear in return. She and her mate were willing to lead him to the tribe. He gave a light sigh of relief.

As he slogged on through the depressing drizzle, the Apache wondered again why the coyotes had left him before and waited in the tower valley. What link was there between the animals of Terra and the remains of the long-ago empire of the stars? For he was certain it was not by chance that Nalik'ideyu and Naginlta had lingered in that misty place. He longed to communicate with them directly, to ask questions and be answered.

Without their aid, Travis would never have been able to track the clan. The drizzle alternated with slashing bursts of rain, torrential enough to drive the trackers to the nearest cover. Overhead the sky was either dull bronze or night black. Even the coyotes paced nose to ground, often making wide casts for the trail while Travis waited.

The rain lasted for three days and nights, filling watercourses with rapidly rising streams. Travis could only hope that the others were having the same difficulty traveling that he was, perhaps the more so since they were burdened with packs. The fact that they kept on meant that they were determined to get as far from the northern mountains as they could.

On the fourth morning the bronze of the clouds slowly thinned into the usual gold, and the sun struck across hills where mist curled like steam from a hundred bubbling pots. Travis relaxed in the welcome warmth, feeling his shirt dry on his shoulders. It was still a waterlogged terrain ahead which should continue to slow the clan. He had high expectations of catching up with them soon, and now the worst of his bruises had faded. His muscles were limber, and he had worked out his plan as best he could.

Two hours later he sat in ambush, waiting for the scout who was walking into his hands. Under the direction of the coyotes, Travis had circled the line of march, come in ahead of the clan. Now he needed an emissary to state his challenge, and the fact that the scout he was about to jump was Manulito, one of Deklay's supporters, suited Travis' purpose perfectly. He gathered his feet under him as the other came opposite, and sprang.

The rush carried Manulito off his feet and face down on the sod while Travis made the best of his advantage and pinned the wildly fighting man under him. Had it been one of the older braves he might not have been so successful, but Manulito was still a boy by Apache standards.

"Lie still!" Travis ordered. "Listen well—so you can say to Deklay the words of the Fox!"

The frenzied struggles ceased. Manulito managed to wrench his head to the left so he could see his captor. Travis loosened his grip, got to his feet. Manulito sat up, his face darkly sullen, but he did not reach for his knife.

"You will say this to Deklay: The Fox says he is a man of little sense and less courage, preferring to throw stones rather than meet knife to knife as does a warrior. If he thinks as a warrior, let him prove it—his strength against my strength—after the ways of the People!"

Some of the sullenness left Manulito's expression. He was eager, excited.

"You would duel with Deklay after the old custom?"

"I would. Say this to Deklay, openly so that all men may hear. Then Deklay must also give answer openly."

Manulito flushed at that implication concerning his leader's courage, and Travis knew that he would deliver the challenge openly. To keep his hold on the clan the latter must accept it, and there would be an audience of his people to witness the success or defeat of their new chief and his policies.

As Manulito disappeared Travis summoned the coyotes, putting full effort into getting across one message. Any tribe led by Deklay would be hostile to the mutant animals. They must go into hiding, run free in the wilderness if the gamble failed Travis. Now they withdrew into the bushes but not out of reach of his mind.

He did not have too long to wait. First came Jil-Lee, Buck, Nolan, Tsoay, Lupe—those who had been with him on the northern scout. Then the others, the warriors first, the women making a half circle behind, leaving a free space in which Deklay walked.

"I am the Fox," Travis stated. "And this one has named me witch and natdahe, outlaw of the mountains. Therefore do I come to name names in my turn. Hear me, People: This Deklay—he would walk among you as 'izesnantan, a great chief—but he does not have the go'ndi, the holy power of a chief. For this Deklay is a fool, with a head filled by nothing but his own wishes, not caring for his clan brothers. He says he leads you into safety; I say he leads you into the worst danger any living man can imagine—even in peyote dreams! He is one twisted in his thoughts, and he would make you twisted also——"

Buck cut in sharply, hushing the murmur of the massed clan.

"These are bold words, Fox. Will you back them?"

Travis' hands were already peeling off his shirt. "I will back them," he stated between set teeth. He had known since his awakening after the stoning that this next move was the only one left for him to make. But now that the testing of his action came, he could not be certain of the outcome, of anything save that the final decision of this battle might affect more than the fate of two men. He stripped, noting that Deklay was doing the same.

Having stepped into the center of the glade, Nolan was using the point of his knife to score a deep-ridged circle there. Naked except for his moccasins, with only his knife in his hand, Travis took the two strides which put him in the circle facing Deklay. He surveyed his opponent's finely muscled body, realizing that his earlier estimate of Deklay's probable advantages were close to the mark. In sheer strength the other outmatched him. Whether Deklay was skillful with his knife was another question, one which Travis would soon be able to answer.

They circled, eyes intent upon each move, striving to weigh and measure each other's strengths and weaknesses. Knife dueling among the Pinda-lick-o-yi, Travis remembered, had once been an art close to finished swordplay, with two evenly matched fighters able to engage for a long time without seriously marking each other. But this was a far rougher and more deadly game, with none of the niceties of such a meeting.

He evaded a vicious thrust from Deklay.

"The bull charges," he laughed. "And the Fox snaps!" By some incredible stroke of good fortune, the point of his weapon actually grazed Deklay's arm, drawing a thin, red inch-long line across the skin.

"Charge again, bull. Feel once more the Fox's teeth!"

He strove to goad Deklay into a crippling loss of temper, knowing how the other could explode into violent rage. It was dangerous, that rage, but it could also make a man blindly careless.

There was an inarticulate sound from Deklay, a dusky swelling in the man's face. He spat, as might an enraged puma, and rushed at Travis who did not quite manage to avoid the lunge, falling back with a smarting slash across the ribs.

"The bull gores!" Deklay bellowed. "Horns toss the Fox!"

He rushed again, elated by the sight of the trickling wound on Travis' side. But the slighter man slipped away.

Travis knew he must be careful in such evasions. One foot across the ridged circle and he was finished as much as if Deklay's blade had found its mark. Travis tried a thrust of his own, and his foot came down hard on a sharp pebble. Through the sole of his moccasin pain shot upward, caused him to stumble. Again the scarlet flame of a wound, down his shoulder and forearm this time.

Well, there was one trick, he knew. Travis tossed the knife into the air, caught it with his left hand. Deklay was now facing a left-handed fighter and must adjust to that.

"Paw, bull, rattle your horns!" Travis cried. "The Fox still shows his teeth!"

Deklay recovered from his instant of surprise. With a cry which was indeed like the bellow of an old range bull, he rushed into grapple, sure of his superior strength against a younger and already wounded man.

Travis ducked, one knee thumping the ground. He groped out with his right hand, caught up a handful of earth, and flung it into the dusky brown face. Again it seemed that luck was on his side. That handful could not be as blinding as sand, but some bit of the shower landed in Deklay's eye.

For a space of seconds Deklay was wide open—open for a blow which would rip him up the middle, the blow Travis could not and would not deliver.

Instead, he took the offensive recklessly, springing straight for his opponent. As the earth-grimed fingers of one hand clawed into Deklay's face, he struck with the other, not with the point of the knife but with its shaft. But Deklay, already only half conscious from the blow, had his own chance. He fell to the ground, leaving his knife behind, two inches of steel between Travis' ribs.

Somehow—he didn't know from where he drew that strength—Travis kept his feet and took one step and then another, out of the circle until the comforting brace of a tree trunk was against his bare back. Was he finished—?

He fought to nurse his rags of consciousness. Had he summoned Buck with his eyes? Or had the urgency of what he had to say reached somehow from mind to mind? The other was at his side, but Travis put out a hand to ward him off.

"Towers—" He struggled to keep his wits through the pain and billowing weakness beginning to creep through him. "Reds mustn't get to the towers! Worse than the bomb ... end us all!"

He had a hazy glimpse of Nolan and Jil-Lee closing in about him. The desire to cough tore at him, but they had to know, to believe....

"Reds get to the towers—everything finished. Not only here ... maybe back home too...."

Did he read comprehension on Buck's face? Would Nolan and Jil-Lee and the rest believe him? Travis could not suppress the cough any longer, and the ripping pain which followed was the worst he had ever experienced. But still he kept his feet, tried to make them understand.

"Don't let them get to the towers. Find that storehouse!"

Travis stood away from the tree, reached out to Buck his earth and bloodstained hand. "I swear ... truth ... this must be done!"

He was going down, and he had a queer thought that once he reached the ground everything would end, not only for him but also for his mission. Trying to see the faces of the men about him was like attempting to identify the people in a dream.

"Towers!" He had meant to shout it, but he could not even hear for himself that last word as he fell.



14

Travis' back was braced against blanketed packs as he steadied a piece of light-yellow bark against one bent knee scowling at the lines drawn on it in faint green.

"We are here then ... and the ship there—" His thumb was set on one point of the crude map, forefinger on the other. Buck nodded.

"That is so. Tsoay, Eskelta, Kawaykle, they watch the trails. There is the pass, two other ways men can come on foot. But who can watch the air?"

"The Tatars say the Reds dare not bring the 'copter into the mountains. After they first landed they lost a flyer in a tricky air-current flow up there. They have only one left and won't risk it. If only they aren't reinforced before we can move!" There it was again, that constant gnawing fear of time, time shortening into a rope to strangle them all.

"You think that the knowledge of our ship will bring them into the open?"

"That—or information about the towers would be the only things important enough to pull out their experts. They could send a controlled Tatar party to explore the ship, sure. But that wouldn't give them the technical reports they need. No, I think if they knew a wrecked Western Confederation ship was here, it would bring them—or enough of them to lessen the odds. We have to catch them in the open. Otherwise, they can hole up forever in that ship-fort of theirs."

"And just how do we let them know our ship is here? Send out another scouting party and let them be trailed back?"

"That's our last resource." Travis continued to frown at the map. Yes, it would be possible to let the Reds sight and trail an Apache party. But there was none in the clan who were expendable. Surely there was some other way of laying the trap with the wrecked ship for bait. Capture one of the Reds, let him escape again, having seen what they wanted him to see? Again a time-wasting business. And how long would they have to wait and what risks would they take to pick up a Red prisoner?

"If the Tatars were dependable...." Buck was thinking aloud.

But that "if" was far too big. They could not trust the Tatars. No matter how much the Mongols wanted to aid in pulling down the Reds, as long as they could be controlled by the caller they were useless. Or were they?

"Thought of something?" Buck must have caught Travis' change of expression.

"Suppose a Tatar saw our ship and then was picked up by a Red hunting patrol and they got the information out of him?"

"Do you think any outlaw would volunteer to let himself be picked up again? And if he did, wouldn't the Reds also be able to learn that he had been set up for the trap?"

"An escaped prisoner?" Travis suggested.

Now Buck was plainly considering the possibilities of such a scheme. And Travis' own spirits rose a little. The idea was full of holes, but it could be worked out. Suppose they capture, say, Menlik, bring him here as a prisoner, let him think they were about to kill him because of that attack back in the foothills. Then let him escape, pursue him northward to a point where he could be driven into the hands of the Reds? Very chancy, but it just might work. Travis was favoring a gamble now, since his desperate one with the duel had paid off.

The risk he had accepted then had cost him two deep wounds, one of which might have been serious if Jil-Lee's project-sponsored medical training had not been to hand. But it had also made Travis one of the clan again, with his people willing to listen to his warning concerning the tower treasury.

"The girl—the Tatar girl!"

At first Travis did not understand Buck's ejaculation.

"We get the girl," the other elaborated, "let her escape, then hunt her to where they'll pick her up. Might even imprison her in the ship to begin with."

Kaydessa? Though something within him rebelled at that selection for the leading role in their drama, Travis could see the advantage of Buck's choice. Woman-stealing was an ancient pastime among primitive cultures. The Tatars themselves had found wives that way in the past, just as the Apache raiders of old had taken captive women into their wickiups. Yes, for raiders to steal a woman would be a natural act, accepted as such by the Reds. For the same woman to endeavor to escape and be hunted by her captors also was reasonable. And for such a woman, cut off from her outlaw kin, to eventually head back toward the Red settlement as the only hope of evading her enemies—logical all the way!

"She would have to be well frightened," Travis observed with reluctance.

"That can be done for us—"

Travis glanced at Buck with sharp annoyance. He would not allow certain games out of their common past to be played with Kaydessa. But Buck had something very different from old-time brutality in mind.

"Three days ago, while you were still flat on your back, Deklay and I went back to the ship—"

"Deklay?"

"You beat him openly, so he must restore his honor in his own sight. And the council has forbidden another duel or challenge," Buck replied. "Therefore he will continue to push for recognition in another way. And now that he has heard your story and knows we must face the Reds, not run from them, he is eager to take the war trail—too eager. So we returned to the ship to make another search for weapons——"

"There were none there before except those we had...."

"Nor now either. But we discovered something else." Buck paused and Travis was shaken out of his absorption with the problem at hand by a note in the other's voice. It was as if Buck had come upon something he could not summon the right words to describe.

"First," Buck continued, "there was this dead thing there, near where we found Dr. Ruthven. It was something like a man ... but all silvery hair——"

"The ape-things! The ape-things from the other worlds! What else did you see?" Travis had dropped the map. His side gave him a painful twinge as he caught at Buck's sleeve. The bald space rovers—did they still exist here somewhere? Had they come to explore the ship built on the pattern of their own but manned by Terrans?

"Nothing except tracks, a lot of them, in every open cabin and hole. I think there must have been a sizable pack of the things."

"What killed the dead one?"

Buck wet his lips. "I think—fear...." His voice dropped a little, almost apologetically, and Travis stared.

"The ship is changed. Inside, there is something wrong. When you walk the corridors your skin crawls, you think there is something behind you. You hear things, see things from the corners of your eyes.... When you turn, there's nothing, nothing at all! And the higher you climb into the ship, the worse it is. I tell you, Travis, never have I felt anything like it before!"

"It was a ship of many dead," Travis reminded him. Had the age-old Apache fear of the dead been activated by the Redax into an acute phobia—to strike down such a level-headed man as Buck?

"No, at first that, too, was my thought. Then I discovered that it was worst not near that chamber where we lay our dead, but higher, in the Redax cabin. I think perhaps the machine is still running, but running in a wrong way—so that it does not awaken old memories of our ancestors now, but brings into being all the fears which have ever haunted us through the dark of the ages. I tell you, Travis, when I came out of that place Deklay was leading me by the hand as if I were a child. And he was shivering as a man who will never be warm again. There is an evil there beyond our understanding. I think that this Tatar girl, were she only to stay there a very short time, would be well frightened—so frightened that any trained scientist examining her later would know there was a mystery to be explored."

"The ape-things—could they have tried to run the Redax?" Travis wondered. To associate machines with the creatures was outwardly pure folly. But they had been discovered on two of the planets of the old civilization, and Ashe had thought that they might represent the degenerate remnants of a once intelligent species.

"That is possible. If so, they raised a storm which drove them out and killed one of them. The ship is a haunted place now."

"But for us to use the girl...." Travis had seen the logic in Buck's first suggestion, but now he differed. If the atmosphere of the ship was as terrifying as Buck said, to imprison Kaydessa there, even temporarily, was still wrong.

"She need not remain long. Suppose we should do this: We shall enter with her and then allow the disturbance we would feel to overcome us. We could run, leave her alone. When she left the ship, we could then take up the chase, shepherding her back to the country she knows. Within the ship we would be with her and could see she did not remain too long."

Travis could see a good prospect in that plan. There was one thing he would insist on—if Kaydessa was to be in that ship, he himself would be one of the "captors." He said as much, and Buck accepted his determination as final.

They dispatched a scouting party to infiltrate the territory to the north, to watch and wait their chance of capture. Travis strove to regain his feet, to be ready to move when the moment came.

Five days later he was able to reach the ridge beyond which lay the wrecked ship. With him were Jil-Lee, Lupe, and Manulito. They satisfied themselves that the globe had had no visitors since Buck and Deklay; there was no sign that the ape-things had returned.

"From here," Travis said, "the ship doesn't look too bad, almost as if it might be able to take off again."

"It might lift," Jil-Lee gestured to the mountaintop behind the curve of the globe—"about that far. The tubes on this side are intact."

"What would happen were the Reds to get inside and try to fly again?" Manulito wondered aloud.

Travis was struck by a sudden idea, one perhaps just as wild as the other inspirations he had had since landing on Topaz, but one to be studied and explored—not dismissed without consideration. Suppose enough power remained to lift the ship partially and then blow it up? With the Red technicians on board at the time.... But he was no engineer, he had no idea whether any part of the globe might or might not work again.

"They are not fools; a close look would tell them it is a wreck," Jil-Lee countered.

Travis walked on. Not too far ahead a yellow-brown shape moved out of the brush, stood stiff-legged in his path, facing the ship and growling in a harsh rumble of sound. Whatever moved or operated in that wreck was picked up by the acute sense of the coyote, even at this distance.

"On!" Travis edged around the snarling animal. With one halting step and then another, it followed him. There was a sharp warning yelp from the brush, and a second coyote head appeared. Naginlta followed Travis, but Nalik'ideyu refused to approach the grounded globe.

Travis surveyed the ship closely, trying to remember the layout of its interior. To turn the whole sphere into a trap—was it possible? How had Ashe said the Redax worked? Something about high-frequency waves stimulating certain brain and nerve centers.

What if one were shielded from those rays? That tear in the side—he himself must have climbed through that the night they crashed. And the break was not too far from the space lock. Near the lock was a storage compartment. And if it had not been jammed, or its contents crushed, they might have something. He beckoned to Jil-Lee.

"Give me a hand—up there."

"Why?"

"I want to see if the space suits are intact."

Jil-Lee regarded Travis with open bewilderment, but Manulito pushed forward. "We do not need those suits to walk here, Travis. This air we can breathe—"

"Not for the air, and not in the open." Travis advanced at a deliberate pace. "Those suits may be insulated in more ways than one——"

"Against a mixed-up Redax broadcast, you mean!" Jil-Lee exclaimed. "Yes, but you stay here, younger brother. This is a risky climb, and you are not yet strong."

Travis was forced to accede to that, waiting as Manulito and Lupe climbed up to the tear and entered. At least Buck and Deklay's experience had forewarned them and they would be prepared for the weird ghosts haunting the interior.

But when they returned, pulling between them the limp space suit, both men were pale, the shiny sheen of sweat on their foreheads, their hands shaking. Lupe sat down on the ground before Travis.

"Evil spirits," he said, giving to this modern phenomenon the old name. "Truly ghosts and witches walk in there."

Manulito had spread the suit on the ground and was examining it with a care which spoke of familiarity.

"This is unharmed," he reported. "Ready to wear."

The suits were all tailored for size, Travis knew. And this fitted a slender, medium-sized man. It would fit him, Travis Fox. But Manulito was already unbuckling the fastenings with practiced ease.

"I shall try it out," he announced. And Travis, seeing the awkward climb to the entrance of the ship, had to agree that the first test should be carried out by someone more agile at the moment.

Sealed into the suit, with the bubble helmet locked in place, the Apache climbed back into the globe. The only form of communication with him was the rope he had tied about him, and if he went above the first level, he would have to leave that behind.

In the first few moments they saw no twitch of alarm running along the rope. After counting fifty slowly, Travis gave it a tentative jerk, to find it firmly fastened within. So Manulito had tied it there and was climbing to the control cabin.

They continued to wait with what patience they could muster. Naginlta, pacing up and down a good distance from the ship, whined at intervals, the warning echoed each time by his mate upslope.

"I don't like it—" Travis broke off when the helmeted figure appeared again at the break. Moving slowly in his cumbersome clothing, Manulito reached the ground, fumbled with the catch of his head covering and then stood, taking deep, lung-filling gulps of air.

"Well?" Travis demanded.

"I see no ghosts," Manulito said, grinning. "This is ghost-proof!" He slapped his gloved hand against the covering over his chest. "There is also this—from what I know of these ships—some of the relays still work. I think this could be made into a trap. We could entice the Reds in and then...." His hand moved in a quick upward flip.

"But we don't know anything about the engines," Travis replied.

"No? Listen—you, Fox, are not the only one to remember useful knowledge." Manulito had lost his cheerful grin. "Do you think we are just the savages those big brains back at the project wished us to be? They have played a trick on us with their Redax. So, we can play a few tricks, too. Me—? I went to M.I.T., or is that one of the things you no longer remember, Fox?"

Travis swallowed hastily. He really had forgotten that fact until this very minute. From the beginning, the Apache team had been carefully selected and screened, not only for survival potential, which was their basic value to the project, but also for certain individual skills. Just as Travis' grounding in archaeology had been one advantage, so had Manulito's technical training made a valuable, though different, contribution. If at first the Redax, used without warning, had smothered that training, perhaps the effects were now fading.

"You can do something, then?" he asked eagerly.

"I can try. There is a chance to booby trap the control cabin at least. And that is where they would poke and pry. Working in this suit will be tough. How about my trying to smash up the Redax first?"

"Not until after we use it on our captive," Jil-Lee decided. "Then there would be some time before the Reds come——"

"You talk as if they will come," cut in Lupe. "How can you be sure?"

"We can't," Travis agreed. "But we can count on this much, judging from the past. Once they know that there is a wrecked ship here, they will be forced to explore it. They cannot afford an enemy settlement on this side of the mountains. That would be, according to their way of thinking, an eternal threat."

Jil-Lee nodded. "That is true. This is a complicated plan, yes, and one in which many things may go wrong. But it is also one which covers all the loopholes we know of."

With Lupe's aid Manulito crawled out of the suit. As he leaned it carefully against a supporting rock he said:

"I have been thinking of this treasure house in the towers. Suppose we could find new weapons there...."

Travis hesitated. He still shrank from the thought of opening the secret places behind those glowing walls, to loose a new peril.

"If we took weapons from there and lost the fight...." He advanced his first objection and was glad to see the expression of comprehension on Jil-Lee's face.

"It would be putting the weapons straight into Red hands," the other agreed.

"We may have to chance it before we're through," Manulito warned. "Suppose we do get some of their technicians into this trap. That isn't going to open up their main defense for us. We may need a bigger nutcracker than we've ever seen."

With a return of that queasy feeling he had known in the tower, Travis knew Manulito was speaking sense. They might have to open Pandora's box before the end of this campaign.

They camped another two days near the wrecked ship while Manulito prowled the haunted corridors and cabins in his space suit, planning his booby trap. At night he drew diagrams on pieces of bark and discussed the possibility of this or that device, sometimes lapsing into technicalities his companions could not follow. But Travis was well satisfied that Manulito knew what he was doing.

On the morning of the third day Nolan slipped into their midst. He was dust-grimed, his face gaunt, the signs of hard travel plain to read. Travis handed him the nearest canteen, and they watched him drink sparingly in small sips before he spoke.

"They come ... with the girl—"

"You had trouble?" asked Jil-Lee.

"The Tatars had moved their camp, which was only wise, since the Reds must have had a line on the other one. And they are now farther to the west. But—" he wiped his lips with the back of his hand—"also we saw your towers, Fox. And that is a place of power!"

"No sign that the Reds are prowling there?"

Nolan shook his head. "To my mind the mists there conceal the towers from aerial view. Only one coming on foot could tell them from the natural crags of the hills."

Travis relaxed. Time still granted them a margin of grace. He glanced up to see Nolan smiling faintly.

"This maiden, she is a kin to the puma of the mountains," he announced. "She has marked Tsoay with her claws until he looks like the ear-clipped yearling fresh from the branding chute——"

"She is not hurt?" Travis demanded.

This time Nolan chuckled openly. "Hurt? No, we had much to do to keep her from hurting us, younger brother. That one is truly as she claims, a daughter of wolves. And she is also keen-witted, marking a return trail all the way, though she does not know that is as we wish. Did we not pick the easiest way back for just that reason? Yes, she plans to escape."

Travis stood up. "Let us finish this quickly!" His voice came out on a rough note. This plan had never had his full approval. Now he found it less and less easy to think about taking Kaydessa into the ship, allowing the emotional torment lurking there to work upon her. Yet he knew that the girl would not be hurt, and he had made sure he would be beside her within the globe, sharing with her the horror of the unseen.

A rattling of gravel down the narrow valley opening gave warning to those by the campfire. Manulito had already stowed the space suit in hiding. To Kaydessa they must have seemed reverted entirely to savagery.

Tsoay came first, an angry raking of four parallel scratches down his left cheek. And behind him Buck and Eskelta shoved the prisoner, urging her on with a show of roughness which did not descend to actual brutality. Her long braids had shaken loose, and a sleeve was torn, leaving one slender arm bare. But none of the fighting spirit had left her.

They thrust her out into the circle of waiting men and she planted her feet firmly apart, glaring at them all indiscriminately until she sighted Travis. Then her anger became hotter and more deadly.

"Pig! Rooter in the dirt! Diseased camel—" she shouted at him in English and then reverted to her own tongue, her voice riding up and down the scale. Her hands were tied behind her back, but there were no bonds on her tongue.

"This is one who can speak thunders, and shoot lightnings from her mouth," Buck commented in Apache. "Put her well away from the wood, lest she set it aflame."

Tsoay held his hands over his ears. "She can deafen a man when she cannot set her mark on him otherwise. Let us speedily get rid of her."

Yet for all their jeering comments, their eyes held respect. Often in the past a defiant captive who stood up boldly to his captors had received more consideration than usual from Apache warriors; courage was a quality they prized. A Pinda-lick-o-yi such as Tom Jeffords, who rode into Cochise's camp and sat in the midst of his sworn enemies for a parley, won the friendship of the very chief he had been fighting. Kaydessa had more influence with her captors than she could dream of holding.

Now it was time for Travis to play his part. He caught the girl's shoulder and pushed her before him toward the wreck.

Some of the spirit seemed to have left her thin, tense body, and she went without any more fight. Only when they came into full view of the ship did she falter. Travis heard her breathe a gasp of surprise.

As they had planned, four of the Apaches—Jil-Lee, Tsoay, Nolan, and Buck—fanned out toward the heights about the ship. Manulito had already gone to cover, to don the space suit and prepare for any accident.

Resolutely Travis continued to propel Kaydessa ahead. At the moment he did not know which was worse, to enter the ship expecting the fear to strike, or to meet it unprepared. He was ready to refuse to enter, not to allow the girl, sullenly plodding on under his compulsion, to face that unseen but potent danger.

Only the memory of the towers and the threat of the Reds finding and exploiting the treasure there kept him going. Eskelta went first, climbing to the tear. Travis cut the ropes binding Kaydessa's wrists and gave her a slight slap between the shoulders.

"Climb, woman!" His anxiety made that a harsh order and she climbed.

Eskelta was inside now, heading for the cabin which might reasonably be selected as a prison. They planned to get the girl as far as that point and then stage their act of being overcome by fear, allowing her to escape.

Stage an act? Travis was not two feet along that corridor before he knew that there would be little acting needed on his part. The thing which pervaded the ship did not attack sharply, rather it seeped into his mind and body as if he drew in poison with every breath, sent it racing along his veins with every beat of a laboring heart. Yet he could not put any name to his feelings, except an awful, weakening fear which weighted him heavier with every step he took.

Kaydessa screamed. Not this time in rage, but with such fervor that Travis lost his hold, staggered back to the wall. She whirled about, her face contorted, and sprang at him.

It was indeed like trying to fight a wildcat and after the first second or two he was hard put to protect his eyes, his face, his side, without injuring her in return. She scrambled over him, running for the break in the wall, and disappeared. Travis gasped, and started to crawl for the break. Eskelta loomed over him, pulled him up in haste.

They reached the opening but did not climb through. Travis was uncertain as to whether he could make that descent yet, and Eskelta was obeying orders in not venturing out too soon.

Below, the ground was bare. There was no sign of the Apaches, though they were in hiding there—and none of Kaydessa. Travis was amazed that she had vanished so quickly.

Still uneasy from the emanation within, they perched within the shadow of the break until Travis thought that the fugitive had a good five-minute start. Then he nodded a signal to Eskelta.

By the time they reached ground level Travis felt a warm wetness spreading under his shielding palm and he knew the wound had opened. He spoke a word or two in hot protest against that mishap, knowing it would keep him from the trail. Kaydessa must be covered all the way back across the pass, not only to be shepherded away from her people and toward the plains where she could be picked up by a Red patrol, but also to keep her from danger. And he had planned from the first to be one of those shepherds.

Now he was about as much use as a trail-lame pony. However, he could send deputies. He thought out his call, and Nalik'ideyu's head appeared in a frame of bush.

"Go, both of you and run with her! Guard—!" He said the words in a whisper, thought them with a fierce intensity as he centered his gaze on the yellow eyes in the pointed coyote face. There was a feeling of assent, and then the animal was gone. Travis sighed.

The Apache scouts were subtle and alert, but the coyotes could far outdo any man. With Nalik'ideyu and Naginlta flanking her flight, Kaydessa would be well guarded. She would probably never see her guards or know that they were running protection for her.

"That was a good move," Jil-Lee said, coming out of concealment. "But what have you done to yourself?" He stepped closer, pulling Travis' hand away from his side. By the time Lupe came to report, Travis was again wound in a strapping bandage pulled tightly about his lower ribs, and reconciled to the fact that any trailing he would do must be well to the rear of the first party.

"The towers," he said to Jil-Lee. "If our plan works, we can catch part of the Reds here. But we still have their ship to take, and for that we need help which we may find at the towers. Or at least we can be on guard there if they return with Kaydessa on that path."

Lupe dropped down lightly from an upper ledge. He was grinning.

"That woman is one who thinks. She runs from the ship first as a rabbit with a wolf at her heels. Then she begins to think. She climbs—" He lifted one finger to the slope behind them. "She goes behind a rock to watch under cover. When Fox comes from the ship with Eskelta, again she climbs. Buck lets himself be seen, so she moves east, as we wish—"

"And now?" questioned Travis.

"She is keeping to the high ways; almost she thinks like one of the People on the war trail. Nolan believes she will hole up for the night somewhere above. He will make sure."

Travis licked his lips. "She has no food or water."

Jil-Lee's lips shaped a smile. "They will see that she comes upon both as if by chance. We have planned all of this, as you know, younger brother."

That was true. Travis knew that Kaydessa would be guided without her knowledge by the "accidental" appearance now and then of some pursuer—just enough to push her along.

"Then, too, she is now armed," Jil-Lee added.

"How?" demanded Travis.

"Look to your own belt, younger brother. Where is your knife?"

Startled, Travis glanced down. His sheath was empty, and he had not needed that blade since he had drawn it to cut meat at the morning meal. Lupe laughed.

"She had steel in her hand when she came out of that ghost ship."

"Took it from me while we struggled!" Travis was openly surprised. He had considered the frenzy displayed by the Tatar girl as an outburst of almost mindless terror. Yet Kaydessa had had wit enough to take his knife! Could this be another case where one race was less affected by a mind machine than the other? Just as the Apaches had not been governed by the Red caller, so the Tatars might not be as sensitive to the Redax.

"She is a strong one, that woman—one worth many ponies." Eskelta reverted to the old measure of a wife's value.

"That is true!" Travis agreed emphatically and then was annoyed at the broadening of Jil-Lee's smile. Abruptly he changed the subject.

"Manulito is setting the booby trap in the ship."

"That is well. He and Eskelta will remain here, and you with them."

"Not so! We must go to the towers——" Travis protested.

"I thought," Jil-Lee cut in, "that you believed the weapons of the old ones too dangerous for us to use."

"Maybe they will be forced into our hands. But we must be sure the towers are not entered by the Reds on their way here."

"That is reasonable. But for you, younger brother, no trailing today, perhaps not tomorrow. If that wound opens again, you might have much bad trouble."

Travis was forced to accept that, in spite of his worry and impatience. And the next day when he did move on he had only the report that Kaydessa had sheltered beside a pool for the night and was doggedly moving back across the mountains.

Three days later Travis, Jil-Lee, and Buck came into the tower valley. Kaydessa was in the northern foothills, twice turned back from the west and the freedom of the outlaws by the Apache scouts. And only half an hour before, Tsoay had reported by mirror what should have been welcome news: the Red helicopter was cruising as it had on the day they watched the hunters enter the uplands. There was an excellent chance of the fugitive's being sighted and picked up soon.

Tsoay had also spotted a party of three Tatars watching the helicopter. But after one wide sweep of the flyer they had taken to their ponies and ridden away at the fastest pace their mounts could manage in this rough territory.

On a stretch of smooth earth Buck scratched a trail, and they studied it. The Reds would have to follow this route to seek the wrecked ship—a route covered by Apache sentinels. And following the chain of communication the result of the trap would be reported to the party at the towers.

The waiting was the most difficult; too many imponderables did not allow for unemotional thinking. Travis was down to the last shred of patience when word came on the second morning at the hidden valley that Kaydessa had been picked up by a Red patrol—drawn out to meet them by the caller.

"Now—the tower weapons!" Buck answered the report with an imperative order to Travis. And the other knew he could no longer postpone the inevitable. And only by action could he blot out the haunting mental picture of Kaydessa once more drawn into the bondage she so hated.

Flanked by Jil-Lee and Buck, he climbed back through the tower window and faced the glowing pillar.

He crossed the room, put out both hands to the sleek pole, uncertain if the weird transport would work again. He heard the sharp gasp from the others as his body was sucked against the pillar and carried downward through the well. Buck followed him, and Jil-Lee came last. Then Travis led the way along the underground corridor to the room with the table and the reader.

He sat down on the bench, fumbled with the pile of tape disks, knowing that the other two were watching him with almost hostile intentness. He snapped a disk into the reader, hoping he could correctly interpret the directions it gave.

He looked up at the wall before him. Three ... four steps, the correct move—and then an unlocking....

"You know?" Buck demanded.

"I can guess——"

"Well?" Jil-Lee moved to the table. "What do we do?"

"This—" Travis came from behind the table, walked to the wall. He put out both hands, flattened his palms against the green-blue-purple surface and slid them slowly along. Under his touch, the material of the wall was cool and hard, unlike the live feel the pillar had. Cool until—

One palm, held at arm's length had found the right spot. He slid the other hand along in the opposite direction until his arms were level with his shoulders. His fingers were able now to press on those points of warmth. Travis tensed and pushed hard with all ten fingers.

At first, as one second and then two passed and there was no response to the pressure, Travis thought he had mistaken the reading of the tape. Then, directly before his eyes, a dark line cut vertically down the wall. He applied more pressure until his fingers were half numb with effort. The line widened slowly. Finally he faced a slit some eight feet in height, a little more than two in width, and there the opening remained.

Light beyond, a cold, gray gleam—like that of a cloudy winter day on Terra—and with it the chill of air out of some arctic wasteland. Favoring his still bandaged side, Travis scraped through the door ahead of the others, and came into the place of gray cold.

"Wauggh!" Travis heard that exclamation from Jil-Lee, could have echoed it himself except that he was too astounded by what he had seen to say anything at all.

The light came from a grid of bars set far above their heads into the native rock which roofed this storehouse, for storehouse it was. There were orderly lines of boxes, some large enough to contain a tank, others no bigger than a man's fist. Symbols in the same blue-green-purple lights of the outer wall shone from their sides.

"What—?" Buck began one question and then changed it to another: "Where do we begin to look?"

"Toward the far end." Travis started down the center aisle between rows of the massed spoils of another time and world—or worlds. The same tape which had given him the clue to the unlocking of the door, emphasized the importance of something stored at the far end, an object or objects which must be used first. He had wondered about that tape. A sensation of urgency, almost of despair, had come through the gabble of alien words, the quick sequence of diagrams and pictures. The message might have been taped under a threat of some great peril.

There was no dust on the rows of boxes or on the floor underfoot. A current of cold, fresh air blew at intervals down the length of the huge chamber. They could not see the next aisle across the barriers of stored goods, but the only noise was a whisper and the faint sounds of their own feet. They came out into an open space backed by the wall, and Travis saw what had been so important.

"No!" His protest was involuntary, but his denial loud enough to echo.

Six—six of them—tall, narrow cases set upright against the wall; and from their depths, five pairs of dark eyes staring back at him in cold measurement. These were the men of the ships—the men Menlik had dreamed of—their bald white heads, their thin bodies with the skintight covering of the familiar blue-green-purple. Five of them were here, alive—watching ... waiting....

Five men—and six boxes. That small fact broke the spell in which those eyes held Travis. He looked again at the sixth box to his right. Expecting to meet another pair of eyes this time, he was disconcerted to face only emptiness. Then, as his gaze traveled downward, he saw what lay on the floor there—a skull, a tangle of bones, tattered material cobwebbed into dusty rags by time. Whatever had preserved five of the star men intact, had failed the sixth of their company.

"They are alive!" Jil-Lee whispered.

"I do not think so," Buck answered. Travis took another step, reached out to touch the transparent front of the nearest coffin case. There was no change in the eyes of the alien who stood within, no indication that if the Apaches could see him, he would be able to return their interest. The five stares which had bemused the visitors at first, did not break to follow their movements.

But Travis knew! Whether it was some message on the tape which the sight of the sleepers made clear, or whether some residue of the driving purpose which had set them there now reached his mind, was immaterial. He knew the purpose of this room and its contents, why it had been made and the reason its six guardians had been left as prisoners—and what they wanted from anyone coming after them.

"They sleep," he said softly.

"Sleep?" Buck caught him up.

"They sleep in something like deep freeze."

"Do you mean they can be brought to life again!" Jil-Lee cried.

"Maybe not now—it must be too long—but they were meant to wait out a period and be restored."

"How do you know that?" Buck asked.

"I don't know for certain, but I think I understand a little. Something happened a long time ago. Maybe it was a war, a war between whole star systems, bigger and worse than anything we can imagine. I think this planet was an outpost, and when the supply ships didn't come any more, when they knew they might be cut off for some length of time, they closed down. Stacked their supplies and machines here and then went to sleep to wait for their rescuers...."

"For rescuers who never came," Jil-Lee said softly. "And there is a chance they could be revived even now?"

Travis shivered. "Not one I would want to take."

"No," Buck's tone was somber, "that I agree to, younger brother. These are not men as we know them, and I do not think they would be good dalaanbiyat'i—allies. They had go'ndi in plenty, these star men, but it is not the power of the People. No one but a madman or a fool would try to disturb this sleep of theirs."

"The truth you speak," Jil-Lee agreed. "But where in this," he turned his shoulder to the sleeping star men and looked back at the filled chamber—"do we find anything which will serve us here and now?"

Again Travis had only the scrappiest information to draw upon. "Spread out," he told them. "Look for the marking of a circle surrounding four dots set in a diamond pattern."

They went, but Travis lingered for a moment to look once more into the bleak and bitter eyes of the star men. How many planet years ago had they sealed themselves into those boxes? A thousand, ten thousand? Their empire was long gone, yet here was an outpost still waiting to be revived to carry on its mysterious duties. It was as if in Saxon-invaded Britain long ago a Roman garrison had been frozen to await the return of the legions. Buck was right; there was no common ground today between Terran man and these unknowns. They must continue to sleep undisturbed.

Yet when Travis also turned away and went back down the aisle, he was still aware of a persistent pull on him to return. It was as though those eyes had set locking cords to will him back to release the sleepers. He was glad to turn a corner, to know that they could no longer watch him plunder their treasury.

"Here!" That was Buck's voice, but it echoed so oddly across the big chamber that Travis had difficulty in deciding what part of the warehouse it was coming from. And Buck had to call several times before Travis and Jil-Lee joined him.

There was the circle-dot-diamond symbol shining on the side of a case. They worked it out of the pile, setting it in the open. Travis knelt to run his hands along the top. The container was an unknown alloy, tough, unmarked by the years—perhaps indestructible.

Again his fingers located what his eyes could not detect—the impressions on the edge, oddly shaped impressions into which his finger tips did not fit too comfortably. He pressed, bearing down with the full strength of his arms and shoulders, and then lifted up the lid.
