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 expressionless 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
