Chapter III: Part 3

They were in a hall where bold bands of color interwove in patterns impossible for Terran eyes to study. Raf lowered his gaze hurriedly to the gray floor under his boots. He had discovered earlier that to try to trace any thread of that wild splashing did weird things to his eyesight and awakened inside him a sick panic. His space boots, with the metal, magnetic plates set in the soles, clicked loudly on the pavement where his companion's bare feet made no whisper of sound.

The hall gave upon a ramp leading down, and Raf recognized this. His confidence arose. They were on their way out of the building. Here the murals were missing so that he could look about him for reference points.

He was sure that the banquet hall was some ten stories above street level. But they did not go down ten ramps now. At the foot of the third the officer turned abruptly to the left, beckoning Raf along. When the Terran remained stubbornly where he was, pointing in the direction which, to him, meant return to the flitter, the other made gestures describing an aircraft in flight. His own probably.

Raf sighed. He could see no way out unless he cut and ran. And long before he reached the street from this warren they could pick him up. Also, in spite of all the precautions he had taken to memorize their way here, he was not sure he could find his path back to the flyer, even if he were free to go. Giving in, he went after the officer.

Their way led out on one of the spider-web bridges which tied building and tower into the complicated web which was the city. Raf, as a pilot of flitter, had always believed that he had no fear of heights. But he discovered that to coast above the ground in a flyer was far different than to hurry at the pace his companion now set across one of these narrow bridges suspended high above the street. And he was sure that the surface under them vibrated as if the slightest extra poundage would separate it from its supports and send it, and them, crashing down.

Luckily the distance they had to cover was relatively short, but Raf swallowed a sigh of relief as they reached the door at the other end. They were now in a tower which, unluckily, proved to be only a way station before another swing out over empty space on a span which sloped down! Raf clutched at the guide rail, the presence of which suggested that not all the users of this road were as nonchalant as the officer who tripped lightly ahead. This must explain the other's bare feet--on such paths they were infinitely safer than his own boots.

The downward sloping bridge brought them to a square building which somehow had an inhabited look which those crowding around it lacked. Raf gained its door to become aware of a hum, a vibration in the wall he touched to steady himself, hinting at the drive of motors, the throb of machinery inside the structure. But within, the officer passed along a corridor to a ramp which brought them out, after what was for Raf a steep climb, upon the roof. Here was not one of the tongue-shaped craft such as had first met them in the city, but a gleaming globe. The officer stopped, his eyes moving from the Terran to the machine, as if inviting Raf to share in his own pride. To the pilot's mind it bore little resemblance to any form of aircraft past or present with which he had had experience in his own world. But he did not doubt that it was the present acme of alien construction, and he was eager to see it perform.

He followed the officer through a hatch at the bottom of the globe, only to be confronted by a ladder he thought at first he could not climb, for the steps were merely toe holds made to accommodate the long, bare feet of the crew. By snapping on the magnetic power of his space boots, Raf was able to get up, although at a far slower speed than his guide. They passed several levels of cabins before coming out in what was clearly the control cabin of the craft.

To Raf the bank of unfamiliar levers and buttons had no meaning, but he paid strict attention to the gestures of his companion. This was not a space ship he gathered. And he doubted whether the aliens had ever lifted from their own planet to their neighbors in this solar system. But it was a long-range ship with greater cruising power than the other flyer he had seen. And it was being readied now for a voyage of some length.

The Terran pilot squatted down on the small stool before the controls. Before him a visa plate provided a clear view of the sky without and the gathering clouds of evening. Raf shifted uncomfortably. That signal of the passing of time triggered his impatience to be away--back to the _RS 10_. He did not want to spend the night in this city. Somehow he must get the officer to take him back to the flitter--to be there would be better than shut up in one of the alien dwellings.

Meanwhile he studied the scene on the visa plate, trying to find the roof on which they had left the flitter. But there was no point he was able to recognize.

Raf turned to the officer and tried to make clear the idea of returning to his own ship. Either he was not as clever at the sign language as the other, or the alien did not wish to understand. For when they left the control cabin, it was only to make an inspection tour of the other parts of the globe, including the space which held the motors of the craft and which, at another time, would have kept Raf fascinated for hours.

In the end the Terran broke away and climbed down the thread of ladder to stand on the roof under the twilight sky. Slowly he walked about the broad expanse of the platform, attempting to pick out some landmark. The central building of the city loomed high, and there were any number of towers about it. But which was the one that guarded the roof where the flitter rested? Raf's determination to get back to his ship was a driving force.

The alien officer had watched him, and now a three-fingered hand was laid on Raf's sleeve while its owner looked into Raf's face and mouthed a trilling question.

Without much hope the pilot sketched the set of gestures he had used before. And he was surprised when the other led the way down into the building. This time they did not go back to the bridge, which had brought them across the canyons of streets, but kept on down ramps within the building.

There was a hum of activity in the place. Aliens, all in tight black wrappings and burnished metal breastplates, their faces barred with black and white paint, went on errands through the halls or labored at tasks Raf could not understand. It now seemed as if his guide were eager to get him away.

It was when they reached the street level that the officer did pause by one door, beckoning Raf imperiously to join him. The Terran obeyed reluctantly--and was almost sick.

He was staring down at a dead, very dead body. By the stained rags still clinging to it, it was one of the aliens, a noble, not one of the black-clad warriors. The gaping wounds which had almost torn the unfortunate apart were like nothing Raf had ever seen.

With a guttural sound which expressed his feelings as well as any words, the officer picked up from the floor a broken spear, the barbed head of which was dyed the same reddish yellow as the blood still seeping from the torn body. Swinging the weapon so close to Raf that the Terran was forced to retreat a step or two to escape contact with the grisly relic, the officer burst into an impassioned speech. Then he went back to the gestures which were easier for the spaceman to understand.

This was the work of a deadly enemy, Raf gathered. And such a fate awaited any one of them who ventured beyond certain bounds of safety. Unless this enemy were destroyed, the city--life itself--was no longer theirs--

Seeing those savage wounds which suggested that an insane fury had driven the attacker, Raf could believe that. But surely a primitive spear was no equal to the weapons his guide could command.

When he tried to suggest that, the other shook his head as if despairing of making plain his real message, and again beckoned Raf to come with him. They were out on the littered street, heading away from the central building where the rest of the Terran party must still be. And Raf, seeing the lengthening shadows, the pools of dusk gathering, and remembering that spear, could not resist glancing back over his shoulder now and then. He wondered if the metallic click of his boot soles on the pavement might not draw attention to them, attention they would not care to meet. His hand was on his stun gun. But the officer gave no sign of being worried; he walked along with the assurance of one who has nothing to fear.

Then Raf caught sight of a patch of color he had seen before and relaxed. They _were_ on their way back to the flitter! He had come down this very street earlier. And he did not mind the long climb back, ramp by steep ramp, which brought him out at last beside the flyer. His relief was so great that he put out his hand to draw it along the sleek side of the craft as he might have caressed a well-loved pet.

"Kurbi?"

At Hobart's bark he stiffened. "Yes, sir!"

"We camp here tonight. Have to make some plans."

"Yes, sir." He agreed with that. To attempt passage of the mountains in the dark was a suicide mission which he would have refused. On the other hand, to his mind, they would sleep more soundly if they were out of the city. He speculated whether he dared suggest that they use the few remaining moments of twilight to head into the open and establish a camp somewhere in the countryside.

The alien officer made some comment in his slurred speech and faded away into the shadows. Raf saw that the others had already dragged out their blanket rolls and were spreading them in the shelter of the flitter while Soriki busied himself at the com, sending back a message to the _RS 10_.

"... should not be too difficult to establish a common speech form," Lablet was saying as Raf climbed into the flitter to tug loose his own roll. "Color and pitch both seem to carry meaning. But the basic pattern is there to study. And with the scanner to sort out those record strips--did you adjust them, Soriki?"

"They're all ready for you to push the button. If the scanner can read them, it will. I got all that speech the chief, or king, or whatever he was, made just before we left."

"Good, very good!" In the light of the portable lamp by Soriki's com, Lablet settled down, plugged the scanner tubes in his ears, absently accepting a ration bar the captain handed him to chew on while he listened to the playback of the record the com-tech had made that afternoon.

Hobart turned to Raf. "You went off with that officer. What did he have to show you?"

The pilot described the globe and the body he had been shown and then added what he had deduced from the sketchy explanations he had been given. The captain nodded.

"Yes, they have aircraft, have been using them, too. But I think that there's only one of the big ones. And they're fighting a war all right. We didn't see the whole colony, but I'll wager that there are only a handful of them left. They're holed up here, and they need help or the barbarians will finish them off. They talked a lot about that."

Lablet pulled the ear plugs from his ears. In the lamplight there was an excited expression on his face. "You were entirely right, Captain! They were offering us a bargain there at the last! They are offering us the accumulated scientific knowledge of this world!"

"What?" Hobart sounded bewildered.

"Over there"--Lablet made a sweep with his arm which might indicate any point to the east--"there is a storehouse of the original learning of their race. It's in the heart of the enemy country. But the enemy as yet do not know of it. They've made two trips over to bring back material and their ship can only go once more. They offer us an equal share if we'll make the next trip in their company and help them clean out the storage place--"

Hobart's answer was a whistle. There was an avid hunger on Lablet's lean face. No more potent bribe could have been devised to entice him. But Raf, remembering the spear-torn body, wondered.

_In the heart of the enemy country_, he repeated to himself.

Lablet added another piece of information. "After all, the enemy they face is only dangerous because of superior numbers. They are only animals--"

"Animals don't carry spears!" Raf protested.

"Experimental animals that escaped during a world-wide war generations ago," reported the other. "It seems that the species have evolved to a semi-intelligent level. I must see them!"

Hobart was not to be hurried. "We'll think it over," he decided. "This needs a little time for consideration."

MANY EYES, MANY EARS

This was not the first time Dalgard had faced the raging fury of a snake-devil thirsting for a kill. The slaying he had done in the arena was an exception to the rule, not the usual hunter's luck. And now that he saw the creature crouched at the far end of the hall he was ready. Sssuri, also, followed their familiar pattern, separating from his companion and slipping along the wall toward the monster, ready to attract its attention at the proper moment.

Only one doubt remained in Dalgard's mind. This devil had not acted in the normal brainless fashion of its kin. What if it was able to assess the very simple maneuvers, which always before had completely baffled its species, and attacked not the moving merman but the waiting archer?

It was backed against another door, a closed one, as if it had fled for refuge to some aid it had expected and did not find. But as Sssuri moved, its long neck straightened until it was almost at right angles with its narrow shoulders, and from its snake's jaws proceeded a horrific hissing which arose to a scream as its leg muscles tensed for a spring.

At just the right moment Sssuri's arm went back, his spear sang through the air. And the snake-devil, with an incredible twist of its neck, caught the haft of the weapon between its teeth, crunching the iron-hard substance into powder. But with that move it exposed its throat, and the arrow from Dalgard's bow was buried head-deep in the soft inner flesh.

The snake-devil spat out the spear and tried to raise its head. But the muscles were already weakening. It fought the poison long enough to take a single step forward, its small red eyes alight with brainless hate. Then it crashed and lay twisting. Dalgard lowered his bow. There was no need for a second shot.

Sssuri regarded the remains of his spear unhappily. Not only was it the product of long hours of work, but no merman ever felt fully equipped to face the world without such a weapon to hand. He salvaged the barbed head and broke it free of the shred of haft the snake-devil had left. Knotting it at his belt he turned to Dalgard.

"Shall we see what lies beyond?"

Dalgard crossed the hall to test the door. It did not yield to an inward push, but rolled far enough into the wall to allow them through.

On the other side was a room which amazed the scout. The colonists had their laboratory, their workshops, in which they experimented and tried to preserve the remnants of knowledge their forefathers had brought across space, as well as to discover new. But the extent of this storehouse with its bewildering mass of odd machines, tanks, bales, and stocked shelves and tables, was too much to be taken in without a careful and minute examination.

"We are not the first to walk here." Sssuri had given little attention to what was stacked about him. Instead he bent over the disturbed dust in one aisle. Dalgard noted as he went to join the merman that there were gaps on those tables which ran the full length of the room, lines left in the grimy deposit of years which told of things recently moved. And then he saw what had interested Sssuri: tracks, some resembling those which his own bare feet might leave, except that there were only three toes!

"_They._"

Dalgard who had been a hunter and a tracker before he was an explorer crouched for a clearer view. Yes, they were recent, yet not made today or even yesterday; there was a thin film of dust resettled in each.

"Some days ago. They are not in the city now," the merman declared with certainty. "But they will come again."

"How do you know that?"

Sssuri's hand swept about to include the wealth around them. "They have taken some, perhaps to them the most needful. But they will not be able to resist gathering the rest. Surely they will return, perhaps not once but many times. Until--"

"Until they come to stay." Dalgard was grim as he completed that sentence for the other.

"That is what they will work for. This land was once under their mastery. This world was theirs before they threw it away warring among themselves. Yes, they dream of holding all once more. But"--Sssuri's yellow eyes took on some of the fire which had shone in those of the snake-devil during its last seconds of life--"that must not be so!"

"If they take the land, you have the sea," Dalgard pointed out. The mermen had a means of escape. But what of his own clansmen? Large families were unknown among the Terran colonists. In the little more than a century they had been on this planet their numbers, from the forty-five survivors of the voyage, had grown to only some two hundred and fifty, of which only a hundred and twenty were old enough or young enough to fight. And for them there was no retreat or hiding place.

"We do not go back to the depths!" There was stern determination in that declaration from Sssuri. His tribe had been long hunted, and it wasn't until they had made a loose alliance with the Terran colonists that they had dared to leave the dangerous ocean depths, where they were the prey of monsters more ferocious and cunning than any snake-devil, to house their families in the coast caves and on the small islands off-shore, to increase in numbers and develop new skills of civilization. No, knowing the stubbornness which was bred into their small, furry bodies, Dalgard did not believe that many of the sea people would willingly go back into the sunless depths. They would not surrender tamely to the rulership of the loathed race.

"I don't see," Dalgard spoke aloud, half to himself, as he studied the tables closely packed, the machines standing on bases about the walls, the wealth of alien technology, "what we can do to stop them."

The restriction drilled into him from early childhood, that the knowledge of Those Others was not for his race and in some way dangerous, gave him an uneasy feeling of guilt just to be standing there. Danger, danger which was far worse than physical, lurked there. And he could bring it to life by merely putting out his hand and picking up any one of those fascinating objects which lay only inches away. For the pull of curiosity was warring inside him against the stern warnings of his Elders.

Once when Dalgard had been very small he had raided his father's trip bag after the next to the last exploring journey the elder Nordis had made. And he had found a clear block of some kind of greenish crystal, in the heart of which threadlike lines of color wove patterns which were utterly strange. When he had turned the block in his hand, those lines had whirled and changed to form new and intricate designs. And when he had watched them intently it had seemed that something happened inside his mind and he knew, here and there, a word, a fragment of alien thought--just as he normally communicated with the cub who was Sssuri or the hoppers of the field. And his surprise had been so great that he had gone running to his father with the cube and the story of what happened when one watched it.

But there had been no praise for his discovery. Instead he had been hurried off to the chamber where an old, old man, the son of the Great Man who had planned to bring them across space, lay in his bed. And Forken Kordov himself had talked to Dalgard in his old voice, a voice as withered and thin as the hands crossed helplessly on his shrunken body, explaining in simple, kindly words that the knowledge which lay in the cubes, in the oddly shaped books which the Terrans sometimes came across in the ruins, was not for them. That his own great-grandfather Dard Nordis, who had been one of the first of the mutant line of sensitives, had discovered that. And Dalgard, impressed by Forken, by his father's concern, and by all the circumstances of that day, had never forgotten nor lost that warning.

"_We_ cannot hope to stop them," Sssuri pointed out. "But we must learn when they will come again and be waiting for them--with your people and mine. For I tell you now, brother of the knife, they must not be allowed to rise once more!"

"And how can we foretell their coming?" Dalgard wanted to know.

"Perhaps that alone we cannot do. But when they come they will not leave speedily. They have stayed here before without harm, and their distrust has been lulled. When next they come, it will be only according to their natures that they will wish to stay longer. Not snatching up the closest to hand of these treasures of theirs, but choosing out with care those things which will give them the best results. Therefore they may make a camp, and we can summon others to aid us."

"To return to Homeport will take several days even if we push," pointed out the scout.

"Word can pass swifter than man," the merman returned, with confidence in his own plan of action. "We shall put other eyes, other ears, many eyes, many ears, to service for us. Be assured we are not the only ones to fear the return of Those Others from overseas."

Dalgard caught his meaning. Yes, it would not be the first time the hoppers and other small animals living in the grasslands, the runners and even the moth birds that only the mermen could mind touch, would relay a message across the land. It might not be an accurate message--to transmit that by small animal brains was impossible--but the meaning would reach both merman and colony Elders: trouble in the north, help needed there. And since Dalgard was the only explorer at present who had chosen the northern trails, his people would know that he had sent that warning and would act upon it, as Sssuri's message would in turn be heeded by the warriors of his tribe.

Yes, it could be done. But what of the traces they had left here--the slaughtered snake-devils--?

Sssuri had an answer for that also. "Let them believe that one of my race came here, or that a party of us ventured to explore inland. We can make it appear that way. But they must not know of you. I do not believe that they ever learned of you or how your fathers came from the sky. And so that may swing the battle in our favor if it comes to open warfare."

What the merman said was sensible enough, and Dalgard was willing to obey orders. As he left the storehouse, Sssuri trailed him, scuffing each dusty print the scout left. Perhaps a master of trailcraft could unravel that spoor, but the colonist was ready to believe that no such master existed in the ranks of Those Others.

In the outer hall the merman approached the now dead snake-devil and jerked from its loose skin the arrow which had killed it. Loosing the head of his ruined spear from his belt, he dug and gouged at the small wound, tearing it so that its original nature was concealed forever. Then they retraced their way through the underground passages until they reached the sanded arena. Already insects buzzed hungrily about the hulks of the dead monsters.

There was a shrill squeal as the remaining infant reptile fled from the pouch where it had hidden. Sssuri hurled his knife, and the blade caught the small devil above the shoulder line, half cutting, half snapping its tender neck, so that it bounded aimlessly on to crash against the wall and fall back squirming feebly.

They collected the darts which had killed the others. Dalgard took the opportunity to study those bands on the forearms of the adults. To his touch they had the slick smoothness of metal, yet he was unfamiliar with the material. It possessed the ruddy fire of copper, but through it ran small black veins. He would have liked to have taken one with him for investigation, but it was out of the question to pry it off that scaled limb.

Sssuri straightened up from his last gruesome bit of stage-setting with a sigh of relief. "Go ahead." He pointed to one of the other archways. "I will confuse the trail."

Dalgard obeyed, treading as lightly as he could, avoiding all stretches in which he could leave a clear print. Sssuri ran lightly back and forth mixing the few impressions to the best of his ability.

They backtracked to the river, retrieved the boat and recrossed, to leave the city behind and strike into the open country beyond its sinister walls. Night was falling, and Dalgard was very glad that he was not to spend the time of darkness within those haunted buildings. But he knew that it was more than a dislike for being shut up in the alien dwellings which had brought Sssuri out into the fields. The second part of their plan must be put into operation.

While Dalgard willed his body motionless, the merman lay relaxed upon the ground before him as he might have floated upon his beloved waves in some secluded cove. His brilliant eyes were closed. Yet Dalgard knew that Sssuri was far from asleep, and with all his own power he tried to join in the broadcast: that urgency which should send some hopper, some night runner, on to spread the rumor that there was trouble in the north, that danger existed and must be investigated. They had already met one colony of runners ranging southward to escape. But if they could send another such tribe traveling, arouse and aim south a hopper exodus, the story would spread until the fringe would reach the animals who lived in peace within touch of Homeport.

The sun was gone, the dark gathered fast. Dalgard could not even see the clustered buildings of the city now. And since he lacked Sssuri's range and staying power, he had no idea whether their efforts had met with even a shadow of success. He shivered in the bite of the wind and dared to lay his hand on Sssuri's shoulder, feeling anew the electric shock of warmth and bursting life which was always there.

Having so broken the other's absorption he asked a question: "Would it not be well, brother of the knife, if with the rising sun you returned to the sea and struck out to join your tribesmen, leaving me here to watch until you return?"

Sssuri's answer came with a speed which suggested that he, too, had been considering that problem. "We shall see what happens with the sun's rising. It is true that in the sea I can travel with greater speed, that there are hunting parties of my people striking into these waters. But they will not come to this city without good reason. It is an accursed place."

With the early morning the city drew them once more. Dalgard's curiosity pulled him to that storehouse. He could not stifle the hope that with luck he might find something there which would solve their problem for them. If there could only be a way to avoid open conflict with Those Others, some solution whereby the aliens need never know of the existence of the Colony. For so many generations, even centuries, the aliens had been confined, or had confined themselves, safely overseas on the western continent. Perhaps if now they were faced by some new catastrophe, they would never attempt to come east again. He had visions of discovering and activating some trap set to protect their treasures which could be turned against them. But he realized that he lacked the technical knowledge which would have aided him in the search for such a weapon.

The remnants of Terran science and mechanics, which the outlaws had brought with them from their native world, had been handed on; the experiments they had managed since with crude equipment had been carefully recorded, and he was acquainted with the outlines of most of them. But the few destructive arms they had imported were long since worn out or lacked charges, and they had not been able to duplicate them. Just as they had torn asunder the ship in which they had crossed space, to use its parts for the building of Homeport, so had they hoarded all else they had brought. But they were limited by lack of materials on Astra, and their fear of the knowledge of the aliens had kept them from experimenting with things found in the ruins.

There might be hundreds of objects on the shelves of that storage place, which, properly used, would reduce not only just the room and its contents to glowing slag, but take half the city with it. But he had no idea which, or which combination, would do it.

And here Sssuri could be no help. The mermen had made great strides forward in biological and mental sciences, but mechanics was a closed section of learning because of their enforced habitat under the sea, and of machines they knew less than the colonists.

"I have been thinking--" Sssuri broke into his companion's chain of reasoning, "of what we may do. And perhaps there is a way to reach the sea more swiftly than by returning overland."

"Downriver? But you said that way may have its watching devices."

"Which would be centered on objects coming upstream, not down. But in this city there should be yet another way--"

He did not enlarge upon that, but since he apparently knew what he was doing, Dalgard let him play guide once more. They recrossed the sluggish river, the scout looking into its murky depths with little relish for it as a means of transportation. Though it had an oily, flowing current, there was a suggestion of stagnant water with unpleasant surprises waiting beneath its turgid surface.

For the second time they entered the arena. Avoiding the bodies, Sssuri made a circuit of the sanded floor. He did not turn in at the archway which led to the storage place, but paused before another as if there lay what he had been searching for.

Dalgard's less sensitive nostrils picked up a new scent, the not-to-be-missed fetor of damp underground ways where water stood. The merman edged around a barred gate as Dalgard sniffed again. The smell of damp was crossed by other and even less appetizing odors, but he did not catch the stench of the snake-devils. And, relying on Sssuri's judgment, he followed the merman into the dark.

Once again patches of violet light glimmered over their heads as the passage narrowed and sloped downward. Dalgard tried to remember the general geography of the section which was above them now. He had assumed that this way with its dank chill must give on the river. But when they had pattered on for a long distance, he knew that either they had passed beneath the stream or that he was totally lost as to direction.

As their eyes adjusted to the gloom of the passage the violet light grew stronger. So Dalgard saw clearly when Sssuri whirled and faced back along the way they had come, his body in a half crouch, his knife ready in his hand.

Dalgard, his bow useless in the damp, drew his own sword-knife. But, though his mind probed and he listened, he could sense or hear nothing on their trail.

AIRLIFT

They were air-borne once more, but Raf was not pleased. In the seat beside him, which Captain Hobart should be occupying, there now squirmed an alien warrior who apparently was uncomfortable in the chair-like depression so different from the low stools he was accustomed to. Soriki was still in the second passenger place, but he, too, shared that with another of the men from the city who rested across bony knees a strange weapon rather like a Terran rifle.

No, the spacemen were not prisoners. According to the official statement they were allies. But, Raf wondered, as against his will he followed the globe in a northeastern course, how long would that fiction last if they refused to fall in with any suggestions the aliens might make? He did not doubt that there was on board the globe some surprise which could shoot the flitter out of the air, if, for example, he adjusted the controls before him and bore west toward the mountains and the safety of the space ship. Either of the aliens he now transported could bring him under control by using those weapons, which might do anything from boiling a man in some unknown ray to smothering him in gas. He had not seen the arms in action, and he did not want to.

Yet Hobart and Lablet did not, as far as he could tell, share his suspicions. Lablet was eager to see the mysterious storehouse, and the captain was either moved by the same desire or else had long since deduced the folly of trying to make a break for it Thus they were now heading seaward with the captain and Lablet sharing quarters with the leaders of the expedition on board the globe, and Raf and the com-tech, with companions--or guards--bringing up the rear. The aliens had even insisted on stripping the flitter of much of its Terran equipment before they left the city, pointing out that the cleared storage space would be filled with salvage when they made the return voyage.

The globe had been trailing along the coastline, and now it angled out to glide over a long finger of cape, rocky and waterworn, which pointed at almost a right angle into the sea. This dwindled into a reef of rock, like the nail on a finger. The sea ahead was no unbroken expanse. Instead there was a series of islands, some merely tops of reefs over which the waves broke, others more substantial, rising well above the threatening water, and one or two showing the green of vegetation.

The chain of islets extended so far out that when the flitter passed over the last one the main continent was out of sight. Now only water stretched beneath them. The globe skidded on as if its pilot had given it an extra burst of power, and Raf accelerated in turn, having no desire to lose his guide. But they were not to make the ocean-wide trip in one jump.

At midday he saw again a break in the smooth carpet of waves, another island, or perhaps the southern tip of a northern continent for the land swept in that direction as far as he could see. The globe spiraled down to make a neat landing on a flat plateau, and Raf prepared to join it. When the undercarriage of the flitter jarred lightly on the rock, he saw signs that this was a man-or alien-fashioned place which must have had much use in the dim past when his new companions ruled all their native world.

The rock had been smoothed off to a flat surface, and at its perimeter were several small domed buildings. Yet, as there had been in the countryside and in the city, except at its very heart, there was an aura of desertion at the site.

Both his alien passengers jumped out of the flitter, as if only too pleased at their release from the Terran flyer. For the first time Raf was shaken out of his own preoccupation with his dislike for the aliens to wonder if they could be moved by a similar distaste for Terrans. Lablet might be interested in that as a scientific problem--the pilot only knew how he felt and that was not comfortable.

Soriki got out and walked across the rock, stretching. But for a long moment Raf remained where he was, behind the controls of the flyer. He was as cramped and tired of travel as the com-tech, perhaps even more so since the responsibility of the flight had been his. And had they landed in open country he would have liked to have thrown himself down on the ground, taking off his helmet and unhooking his tunic collar to let the fresh wind blow through his hair and across his skin. Perhaps that would take away the arid dust of centuries, which, to his mind, had grimed him since their hours in the city. But here was no open country, only a landing space which reminded him too much of the roof of the building in the metropolis.

A half-dozen of the breastplated warriors filed out of the globe and went to the nearest dome, returning with heavy boxes. Fuel--supplies--Raf shrugged off the problem. The pilot was secretly relieved when Captain Hobart dropped out of the hatch in the globe and made his way over to the flitter.

"Everything running smoothly?" he asked with a glance at the two aliens who were Raf's passengers.

"Yes, sir. Any idea how much farther--?" Raf questioned.

Hobart shrugged. "Until we work out basic language difficulties," he muttered, "who knows anything? There is at least one more of these way stations. They don't run on atomics, need some kind of fuel, and they have to have new supplies every so often. Their head man can't understand why it isn't necessary for us to do the same."

"Has he suggested that his techneers want a look at our motors, sir?"

Hobart unbent a little. It was as if in that question he had read something which pleased him. "So far we've managed not to understand that. And if anyone tries it on his own, refer him to me--understand?"

"Yes, sir!" Some of the relief in Raf's tone came through, and he saw that the captain was watching him narrowly.

"You don't like these people, Kurbi?"

The pilot replied with the truth. "I don't feel easy with them, sir. Not that they've shown any unfriendliness. Maybe it's because they're alien--"

He had said the wrong thing and knew it immediately.

"That sounds like prejudice, Kurbi!" Hobart's voice carried the snap of a reprimand.

"Yes, sir," Raf said woodenly. That had done it as far as the captain was concerned. The fierce racial and economical prejudices which had been the keystones of the structure of Pax had left their shadow on Terra's thinking. Nowadays a man would better be condemned for murder than for prejudice against another--it was the unforgivable crime. And in that unconsidered answer Raf had rendered unreliable in the eyes of authority any future report on the aliens which he might be forced to make.

Silently cursing his lack of judgment, Raf made a careful check of the flyer, which might not be necessary but going through the motions of doing his duty gave him some relief. Once the idea struck him of claiming some trouble that would take them back to the spacer for repairs. But Hobart was too good a mechanic himself not to see through that.

They covered the second stage of their flight by evening, this time putting down on an island where, by some ancient and titanic feat of labor, the top had been sheared off a central mountain to make a base. A ring of reefs cut off the land from the action of the waves. At once a party of aliens left the main company and made their way down the mountain to prowl along the shore. They made a discovery of sorts, for Raf saw them ring in some object they had pulled up on the sand. What it was and what meaning it had for them they did not try to explain to the Terrans.

The party spent the night there, the four spacemen wrapped in their sleeping rolls by the flitter, the aliens in their globe ship. The Terrans did not miss the fact that the others had unobtrusively posted guards at the only two places where the mountain could be climbed. And each of those guards cradled in the crook of his arm one of the rifle weapons.

They were aroused shortly after dawn. As far as Raf could see the island was barren of life, or else any creature native to it kept prudently out of the way while the flyers were there. They took off, the globe rising like a balloon into the morning sky, the flitter waiting until it was air-borne before scaling after it.

The mountainous island where they had based was the sea sentinel of an archipelago, which they saw spread out below them as if someone had flung a handful of pebbles into a shallow pool. Most of the islands were merely rocky crags. But there were two which showed the green of small open fields, and Raf thought he caught a glimpse of a dome house on the last.

They were now over a region thick with islands, the first collection giving way to a second and then a third. Raf, expecting no sudden move on the part of the globe he trailed, was startled when the alien ship made a downward swoop. At the same time the warrior seated beside him tugged at the sleeve of his tunic and jabbed a finger toward the ground, clearly an order to follow. Raf cut speed and cautiously lost altitude, determined that he was not going to be rushed into any move for which he did not know the reason.

The globe was hovering over a small island set a little apart from the others. A moment later Soriki's excited voice drew Raf's attention from his controls to what was going on below.

"There's, people down there! Look at them run!"

They were too far away to be sure of the nature of the brown-gray things so close to the color of the sea-washed rock that they could only be detected when they moved. But it was evident that they were alive, and as Raf brought the flitter closer, he was also certain that they ran on their two hind feet instead of on an animal's four pads.

From the under part of the globe ship licked a tongue of fire. With the force of a whiplash it coursed across the rock and in its passing embrace, the creatures below writhed and withered to charred heaps. They had no chance under that methodical blasting. The alien beside Raf signaled again for a drop. He patted the weapon that he held and motioned for Raf to release the covering of the windshield. But the pilot shook his head firmly.

This might be war. The aliens could have a very good reason for their deadly attack on the creatures surprised below. But he wanted no part of it, nor did he want to get any closer to the scene of slaughter. And he made an emphatic gesture that the windshield could not be opened while the flitter was air-borne.

But as he did so they glided down, and he caught a single good look at what was going on on the rock--a look which remained to haunt his dreams for long years to come. For now he saw clearly the creatures who ran fruitlessly for safety. Some reached the edge of the cliff and leaped to what was an easier death in the sea. But too many others could not make it and died in flaming agony. And they were not all of one size!

Children! There was no mistaking the infant in its mother's arms, the two small ones who fled hand in hand until one stumbled and the burning lash caught them both as the other strove to pull the fallen to its feet. Raf gagged. He triggered the controls and soared up and away, fighting the heaving in his middle, shaking off with one savage jerk the insistent pawing hand of the alien who wanted to join in the fun.

"Did you see that?" he demanded of Soriki.

For once the com-tech sounded subdued. "Yes," he replied shortly.

"Those were children," Raf hammered home the point.

"Young ones anyway," the com-tech conceded. "Maybe they aren't people. They had fur all over them--"

Raf grinned mirthlessly. Should he now accuse Soriki of prejudice? What did it matter if a thinking creature was clothed in a space suit, silken bandages, or natural fur--it was still a thinking creature. And he was sure that those had been intelligent creatures he had just seen blasted without a chance to fight back. If these were the enemy the aliens feared, he could understand the vicious cruelty of the attack which had killed the man he had been shown back in the city. Fire against primitive spears was not equal, and when the spears got their chance they must make up for much to balance the scales of justice.

He did not even wonder why his emotions were so wholeheartedly enlisted upon the side of the furred people. Nor did he try to analyze his feelings. He was only sure that more than ever he wanted to be free of the aliens and out of this whole venture.

The warrior sharing his seat was sulking now, twisting about to look back at the island as Raf circled in ever-widening glides to get away from the site and yet not lose track of the globe when it would have finished its dirty business and take once more to the air. But the alien ship was in no hurry to leave.

"They are making sure," Soriki reported. "Giving the whole island a fire bath. I wonder what that stuff is--"

"I'd just as soon not know," Raf returned from between set teeth. "If that is one of their pieces of precious knowledge, we're as well off without it--" he stopped short. Perhaps he had said too much. But Terra had been racked by the torrid horror of atomic war, until all his kind had been so revolted that it was bred into them not to meddle again with such weapons. And war by fire aroused in them that old horror. Surely Soriki must feel it too, and when the com-tech did not comment, Raf was sure of that. He hoped that the slaughter had made some impression on the captain and on Lablet into the bargain.

But when, as if sated with killing, the globe rose again from its position over the island, moving almost sluggishly into the fresh sky, he had to follow it on. More islands were below, and he feared that each one might show some sign of life and tempt the killers to a second hunting.

Luckily that did not happen. The chains of islands became a cape as they had on the coast of the western continent. And now the globe swung to the south, trailing the shore line. Forests made green splotches with bluish overtones running from the sea cliffs back to carpet the land. So far no signs of civilization were to be seen. This land was as untouched as that where the spacer had landed.

Then they saw the bay, stretching out wide arms to engulf the sea. It could have harbored a whole fleet. And marching down to its waters were broad levels of buildings, a giant's staircase leading from sea to cliff tops.

"They had it here--!"

Raf saw what Soriki meant by that outburst. Destruction had struck. He had seen the atomic ruins of his own world, those which were free enough from radiation to explore. But he had never seen anything like these chilling scars. In long strips the very stone which provided foundation for the tiered city had been churned and boiled, had run in rivulets of lava down to the sea, enclosing narrow tongues of still untouched structures. The fire whip the globe had used, magnified to some infinitely greater extent--? It could be.

The alien at his side pressed tightly against the windshield gazing down at the ruins. And now he mouthed a gabble of words which was echoed by his fellow sitting with Soriki. Their excitement must mean that this was their goal. Raf slacked speed, waiting for the globe to point a way to a landing.

But to his surprise the alien ship shot forward inland. The long day was almost over as they came to a second city with a river knotting a ribbon through its middle. Here were no traces of the fury which had laded the seaport with havoc. This collection of buildings seemed whole and perfect.

There was, oddly enough, no landing strip within the city. The globe coasted over the rough oval and came down in open fields to the west. It was a maneuver which Raf copied, though he first dropped a flare as a precaution and brought the flier down in its red glare, with the warrior expressing shrill disapproval.

"I don't think they like fireworks," Soriki remarked.

Raf snorted. "So they don't like fireworks! Well, I don't like crack-ups, and I'm the pilot!" But he didn't believe that the com-tech was really protesting. Soriki had been very quiet since they had witnessed the attack on the island.

"Grim-looking place," was his second comment as they touched ground.

Since Raf privately had held that opinion of all the alien settlements he had so far seen, he agreed. Their two alien passengers were out of the flitter as soon as he opened the bubble shield. And as they stood by the Terran flyer, they held their weapons ready, facing out into the dusk as if they half expected trouble. After the earlier episode that day, Raf did not wonder at their preparedness. Terror begets terror, and ruthlessness arouses retaliation in kind.

"Kurbi! Soriki!" Hobart's voice sounded out of the shadows. "Stay where you are for the present."

Soriki settled deeper in his seat. "He doesn't have to tell me to brake jets," he muttered. "I like it here--"

Raf did not need to echo that. He had a strong surmise that had he been tempted to roam away from the flitter the move would not have been encouraged by the alien guardsmen. If this was their treasure city, they would not welcome any independent investigation by strangers.

When the captain joined them, he was accompanied by the officer who had first shown Raf the globe. And the warrior was either disturbed or angry, for he was talking in a steady stream and his hands were whirling in explanatory gestures.

"They didn't like that flare," Hobart remarked. But there was no reproof in his words. As a spacer pilot he knew that Raf had only done what duty demanded. "We're to remain here--for the night."

"Where's Lablet?" Soriki wanted to know.

"He's staying with Yussoz, the alien commander. He thinks he has the language problem about solved."

"Good enough." Soriki pulled out his bed roll. "We're out of touch with the ship--"

There was a second of silence, unduly prolonged it seemed to Raf. Then Hobart spoke:

"We couldn't expect to keep in call forever. The best com has its range. When did you lose contact?"

"Just before these wrapped-up heroes played with fire back there. I gave the boys all I knew up until then. They know we were headed west, and they had us beamed as long as they could."
