Their probe, if fortune favored them, might become a gate through time. The installation was a vast improvement over these passage points they had first devised. Technical information had taken a vast leap forward after Terran engineers and scientists had had access to the tapes of the stellar empire. Adaptations and shortcuts developed, so that a new hybrid technology came into use, woven from the knowledge and experimentation of two civilizations thousands of years apart in time.
If and when he or Ashe—or Karara and her dolphins—discovered the proper site, the two Agents could set up their own equipment. Both Ross and Ashe had had enough drill in the process. All they needed was the brick of discovery; then they could build their wall. But they must find some remainder of the past, the smallest trace of ancient ruin upon which to center their peep-probe. And since landing here the long days had flowed into weeks with no such discovery made.
Ross crossed the ridge of rock which formed a cocks-comb rise on the island's spine and descended to the village. As they had been trained, the Polynesian settlers adapted native products to their own heritage of building and tools. It was necessary that they live off the land, for their transport ship had had storage space only for a limited number of supplies and tools. After it took off to return home they would be wholly on their own for several years. Their ship, a silvery ball, rested on a rock ledge, its pilot and crew having lingered to learn the results of Ashe's search. Four days more and they would have to lift for home even if the Agents still had only negative results to report.
That disappointment was driving Ashe, the way that six months earlier his outrage and guilt feelings over the Topaz affair had driven him. Karara's suggestion carried weight the longer Ross thought about it. With more swimmers hunting, there was just that much increased chance of turning up some clue. So far the dolphins had not reported any dangerous native sea life or any perils except the natural ones any diver always had at his shoulder under the waves.
There were extra gill-packs, and all of the settlers were good swimmers. An organized hunt ought to shake the Polynesians out of their present do-it-tomorrow attitude. As long as they had had definite work before them—the unloading of the ship, the building of the village, all the labors incidental to the establishing of this base—they had shown energy and enthusiasm. It was only during the last couple of weeks that the languor which appeared part of the atmosphere here had crept up on them, so that now they were content to live at a slower and lazier pace. Ross remembered Ashe's comparison made the evening before, likening Hawaika to a legendary Terran island where the inhabitants lived a drugged existence, feeding upon the seeds of a native plant. Hawaika was fast becoming a lotus land for Terrans.
"Through here, then westward...." Ashe hunched over the crate table in the mat-walled house. He did not look up as Ross entered. Karara's still damp head was bowed until those black locks, now sleeked to her round skull, almost touched the man's close-cropped brown hair. They were both studying a map as if they saw not lines on paper but the actual inlets and lagoons which that drawing represented.
"You are sure, Gordon, that this is the modern point to match the site on the tape?" The girl brushed back straying hair.
Ashe shrugged. There were tight brackets about his mouth which had not been there six months ago. He moved jerkily, not with the fluid grace of those old days when he had faced the vast distance of time travel with unruffled calm and a self-confidence to steady and support the novice Ross.
"The general outline of these two islands could stand for the capes on this—" He pulled a second map, this on transparent plastic, to fit over the first. The capes marked on the much larger body of land did slip over the modern islands with a surprising fit. The once large island, shattered and broken, could have produced the groups of atolls and islets they now prospected.
"How long—" Karara mused aloud, "and why?"
Ashe shrugged. "Ten thousand years, five, two." He shook his head. "We have no idea. It's apparent that there must have been some world-wide cataclysm here to change the contours of the land masses so much. We may have to wait on a return space flight to bring a 'copter or a hydroplane to explore farther." His hand swept beyond the boundaries of the map to indicate the whole of Hawaika.
"A year, maybe two, before we could hope for that," Ross cut in. "Then we'll have to depend on whether the Council believes this important enough." The contrariness which spiked his tongue whenever Karara was present made him say that without thinking. Then the twitch of Ashe's lip brought home Ross's error. Gordon needed reassurance now, not a recitation of the various ways their mission could be doomed.
"Look here!" Ross came to the table, his hand sweeping past Karara, as he used his forefinger for a pointer. "We know that what we want could be easily overlooked, even with the dolphins helping us to check. This whole area's too big. And you know that it is certain that whatever might be down there would be hidden with sea growths. Suppose ten of us start out in a semi-circle from about here and go as far as this point, heading inland. Video-cameras here and here ... comb the whole sector inch by inch if we have to. After all, we have plenty of time and manpower."
Karara laughed softly. "Manpower—always manpower, Ross? But there is woman-power, too. And we have perhaps even sharper sight. But this is a good idea, Gordon. Let me see—" she began to tell off names on her fingers, "PaKeeKee, Vaeoha, Hori, Liliha, Taema, Ui, Hono'ura—they are the best in the water. Me ... you, Gordon, Ross. That makes ten with keen eyes to look, and always there are Tino-rau and Taua. We will take supplies and camp here on this island which looks so much like a finger crooked to beckon. Yes, somehow that beckoning finger seems to me to promise better fortune. Shall we plan it so?"
Some of the tight look was gone from Ashe's face, and Ross relaxed. This was what Gordon needed—not to be sitting in here going over maps, reports, reworking over and over their scant leads. Ashe had always been a field man; and the settlement work had been stultifying, a laborious chore for him.
When Karara had gone Ross dropped down on the bunk against the side wall.
"What did happen here, do you think?" Half was real interest in the mystery they had mulled over and over since they had landed on a Hawaika which diverged so greatly from the maps; the other half, a desire to keep Ashe thinking on a subject removed from immediate worries. "An atomic war?"
"Could be. There are old radiation traces. But these aliens had, I'm sure, progressed beyond atomics. Suppose, just suppose, they could tamper with the weather, with the balance of the planet's crust? We don't know the extent of their powers, how they would use them. They had a colony here once, or there would have been no guide tape. And that is all we are sure of."
"Suppose"—Ross rolled over on his stomach, pillowed his head on his arms—"we could uncover some of that knowledge—"
The twitch was back at Ashe's lips. "That's the risk we have to run now."
"Risk?"
"Would you give a child one of those hand weapons we found in the derelict?"
"Naturally not!" Ross snapped and then saw the point. "You mean—we aren't to be trusted?"
The answer was plain to read in Ashe's expression.
"Then why this whole setup, this hunt for what might mean trouble?"
"The old pinch, the bad one. What if the Reds discover something first? They drew some planets in the tape lottery, remember. It's a seesaw between us—we advance here, they there. We have to keep up the race or lose it. They must be combing their stellar colonies for a few answers just as furiously as we are."
"So, we go into the past to hunt if we have to. Well, I think I could do without answers such as the Baldies would know. But I will admit that I would like to know what did happen here—two, five, ten thousand years ago."
Ashe stood up and stretched. For the first time he smiled. "Do you know, I rather like the idea of fishing off Karara's beckoning finger. Maybe she's right about that changing our luck."
Ross kept his face carefully expre
ssionless as he got up to prepare their evening meal.

Lair of Mano-Nui
Just under the surface of the water the sea was warm, weird life showed colors Ross could name, shades he could not. The corals, the animals masquerading as plants, the plants disguised as animals which inhabited the oceans of Terra, had their counterparts here. And the settlers had given them the familiar names, though the crabs, the fish, the anemones, and weeds of the shallow lagoons and reefs were not identical with Terran creatures. The trouble was that there was too much, such a wealth of life to attract the eyes, hold attention, that it was difficult to keep to the job at hand—the search for what was not natural, for what had no normal place here.
As the land seduced the senses and bewitched the off-worlder, so did the sea have its enchantment to pull one from duty. Ross resolutely skimmed by a forest of weaving, waving lace which varied from a green which was almost black to a pale tint he could not truly identify. Among those waving fans lurked ghost-fish, finned swimmers transparent enough so that one could sight, through their pallid sides, the evidences of recently ingested meals.
The Terrans had begun their sweep-search a half hour ago, slipping overboard from a ferry canoe, heading in toward the checkpoint of the finger isle, forming an arc of expert divers, men and girls so at home in the ocean that they should be able to make the discovery Ashe needed—if such did exist.
Mystery built upon mystery on Hawaika, Ross thought as he used his spear-gun to push aside a floating banner of weed in order to peer below its curtain. The native life of this world must always have been largely aquatic. The settlers had discovered only a few small animals on the islands. The largest of which was the burrower, a creature not unlike a miniature monkey in that it had hind legs on which it walked erect and forepaws, well clawed for digging purposes, which it used with as much skill and dexterity as a man used hands. Its body was hairless and it was able to assume, chameleon-like, the color of the soil and rocks where it denned. The head was set directly on its bowed shoulders without vestige of neck; and it had round bubbles of eyes near the top of its skull, a nose which was a single vertical slit, and a wide mouth fanged for crushing the shelled creatures on which it fed. All in all, to Terran eyes, it was a vaguely repulsive creature, but as far as the settlers had been able to discover it was the highest form of land life. The smaller rodentlike things, the two species of wingless diving birds, and an odd assortment of reptiles and amphibians sharing the island were all the burrowers' prey.
A world of sea and islands, what type of native intelligent life had it once supported? Or had this been only a galactic colony, with no native population before the coming of the stellar explorers? Ross hovered above a dark pocket where the bottom had suddenly dipped into a saucer-shaped depression. The sea growth about the rim rippled in the water raggedly, but there was something about its general outline....
Ross began a circumference of that hollow. Allowing for the distortion of the growths which had formed lumpy excrescences or reached turrets toward the surface—yes, allowing for those—this was decidedly something out of the ordinary! The depression was too regular, too even, Ross was certain of that. With a thrill of excitement he began a descent into the cup, striving to trace signs which would prove his suspicion correct.
How many years, centuries, had the slow coverage of the sea life gathered there, flourished, died, with other creatures to build anew on the remains? Now there was only a hint that the depression had other than a natural beginning.
Anchoring with a one-handed grip on a spike of Hawaikan coral—smoother than the Terran species—Ross aimed the butt of his spear-gun at the nearest wall of the saucer, striving to reach into a crevice between two lumps of growth and so probe into what might lie behind. The spear rebounded; there was no breaking that crust with such a fragile tool. But perhaps he would have better luck lower down.
The depression was deeper than he had first judged. Now the light which existed in the shallows vanished. Red and yellow as colors went, but Ross was aware of blues and greens in shades and tints which were not visible above. He switched on his diving torch, and color returned within its beam. A swirl of weed, pink in the light, became darkly emerald beyond as if it possessed the chameleon ability of the burrowers.
He was distracted by that phenomenon, and so he transgressed the diver's rule of never becoming so absorbed in surroundings as to forget caution. Just when did Ross become aware of that shadow below? Was it when a school of ghost-fish burst unexpectedly between weed growths, and he turned to follow them with the torch? Then the outer edge of his beam caught the movement of a shape, a flutter in the water of the gloomy depths.
Ross swung around, his back to the wall of the saucer, as he aimed the torch down at what was arising there. The light caught and held for a long moment of horror something which might have come out of the nightmares of his own world. Afterward Ross knew that the monster was not as large as it seemed in that endless minute of fear, perhaps no bigger than the dolphins.
He had had training in shark-infested seas on Terra, been carefully briefed against the danger from such hunters of the deep and ocean jungles. But this kind of thing had only existed before in the fairy tales of his race as the dragon of old lore. A scaled head with wide eyes gleaming in the light beam with cold and sullen hate, a gaping mouth fang-filled, a horn-set muzzle, that long, undulating neck and, below it, the half-seen bulk of a monstrous body.
His spear-gun, the knife at his waist belt, neither were protection against this! Yet to turn his back on that rising head was more than Ross could do. He pulled himself back against the wall of the saucer. The thing before him did not rush to attack. Plainly it had seen him and now it moved with the leisure of a hunter having no fears concerning the eventual outcome of the hunt. But the light appeared to puzzle it and Ross kept the beam shining straight into those evil eyes.
The shock of the encounter was wearing off; now Ross edged his flipper into a crevice to hold him steady while his hand went to the sonic-com at his waist. He tapped out a distress call which the dolphins could relay to the swimmers. The swaying dragon head paused, held rigid on a stiff, scaled column in the center of the saucer. That sonic vibration either surprised or bothered the hunter, made it wary.
Ross tapped again. The belief that if he tried to escape, he was lost, that only while he faced it so had he any chance, grew stronger. The head was only inches below the level of his flippered feet as he held to the weeds.
Again that weaving movement, the rise of head, a tremor along the serpent neck, an agitation in the depths. The dragon was on the move again. Ross aimed the light directly at the head. The scales, as far as he could determine, were not horny plates but lapped, silvery ovals such as a fish possessed. And the underparts of the monster might even be vulnerable to his spear. But knowing the way a Terran shark could absorb the darts of that weapon and survive, Ross feared to attack except as a last resort.
Above and to his left there was a small hollow where in the past some portion of the growths had been ripped away. If he could fit himself into that crevice, perhaps he could keep the dragon at bay until help arrived. Ross moved with all the skill he had. His hand closed upon the edge of the niche and he whirled himself up, just making it into that refuge as the head lashed at him wickedly. His suspicion that the dragon would attack anything on the run was well founded, and he knew he had no hope of winning to the surface above.
Now he stood in the crevice, facing outward, watching the head darting in the water. He had switched off the torch, and the loss of light appeared to bewilder the reptile for some precious seconds. Ross pulled as far back into the niche as he could, until the point of one shoulder touched a surface which was sleek, smooth, and cold. The shock of that contact almost sent him hurtling out again.
Gripping the spear before him in his right hand, Ross cautiously felt behind him with the left. His finger tips glided over a seamless surface where the growths had been
torn or peeled away. Though he could not, or dared not, turn his head to see, he was certain that this was his proof that the walls of the saucer had been fashioned and placed there by some intelligent creature.
The dragon had risen, hovering now in the water directly before the entrance to Ross's hole, its neck curled back against its bulk. It had wide flippers moving like planes to hold it poised. The body, sloping from a massive round of shoulders to a tapering rear, was vaguely familiar. If one provided a Terran seal with a gorgon head and scales in place of fur, the effect would be similar. But Ross was assuredly not facing a seal at this moment.
Slight movement of the flippers kept it as stabilized as if it sprawled on a supporting surface. With the neck flattened against the body, the head curved downward until the horn on its snout pointed the tip straight at Ross's middle. The Terran steadied his spear-gun. The dragon's eyes were its most vulnerable targets; if the creature launched the attack, Ross would aim for them.
Both man and dragon were so intent upon their duel that neither was conscious of the sudden swirl overhead. A sleek dark shape struck down, skimming across the humped-back ridge of the dragon. Some of the settlers had empathy with the dolphins to a high degree, but Ross's own powers of contact were relatively feeble.
Only now he was given an assurance of aid, and a suggestion to attack. The dragon head writhed, twisted as the reptile attempted to see above and behind its own length. But the dolphin was only a streak fast disappearing. And that writhing changed the balance the monster had maintained, pushing it toward Ross.
The Terran fired too soon and without proper aim, so the dart snaked past the head. But the harpoon line half hooked about the neck and seemed to confuse the creature. Ross squirmed as far back as he could into his refuge and drew his knife. Against those fangs the weapon was an almost useless toy, but it was all he had.
