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.
Again the dolphin dived in attack on the reptile, this time seizing in its mouth the floating cord of the harpoon and giving it a jerk which jolted the dragon even more off balance, pulling it away from Ross's niche and out into the center of the saucer.
There were two dolphins in action now, Ross saw, playing the dragon as matadors might play a bull, keeping the creature disturbed by their agile maneuvers. Whatever prey came naturally to the Hawaikan monster was not of this type, and the creature was not prepared to deal effectively with their teasing, dodging tactics. Neither had touched the beast, but they kept it constantly striving to get at them.
Though it swam in circles attempting to face its teasers, the dragon did not abandon the level before Ross's refuge, and now and then it darted its head at him, unwilling to give up its prey. Only one of the dolphins frisked and dodged above now as the sonic on Ross's belt vibrated against his lower ribs with its message warning to be prepared for further action. Somewhere above, his own kind gathered. Hurriedly he tapped out in code his warning in return.
Two dolphins busy again, their last dive over the dragon pushing the monster down past Ross's niche toward the saucer's depths. Then they flashed up and away. The dragon was rising in turn, but coming to meet the Hawaikan creature was a ball giving off light, bringing sharp vision and color with it.
Ross's arm swung up to shield his eyes. There was a flash; such answering vibration carried through the waves that even his nerves, far less sensitive than those of the life about him, reacted. He blinked behind his mask. A fish floated by, spiraling up, its belly exposed. And about him growths drooped, trailed lifelessly through the water; while there was a now motionless bulk sinking to the obscurity of the depression floor. A weapon perfected on Terra to use against sharks and barracuda had worked here to kill what could have been more formidable prey.
The Terran wriggled out of the niche, rose to meet another swimmer. As Ashe descended, Ross relayed his news via the sonic. The dolphins were already nosing into the depths in pursuit of their late enemy.
'Look here—' Ross guided Ashe to the crevice which had saved him, aimed the torch beam into it. He had been right! There was a long groove in the covering built up by the growths; a vertical strip some six feet long, of a uniform gray, showed. Ashe touched the find and then gave the alert via the sonic code.
'Metal or an alloy, we've found it!'
But what did they have? Even after an hour's exploration by the full company, Ashe's expert search with his knowledge of artifacts and ancient remains, they were still baffled. It would require labor and tools they did not have, to clear the whole of the saucer. They could be sure only of its size and shape, and the fact that its walls were of an unknown substance which the sea could cloak but not erode. For the length of gray surface showed not the slightest pitting or time wear.
Down at its centermost point they found the dragon's den, an arch coated with growth, before which sprawled the body of the creature. That was dragged aloft with the dolphins' aid, to be taken ashore for study. But the arch itself ... was that part of some old installation?
Torches to the fore, they entered its shadow, only to remain baffled. Here and there were patches of the same gray showing in its interior. Ashe dug the butt of his spear-gun into the sand on the flooring to uncover another oval depression. But what it all signified or what had been its purpose, they could not guess.
'Set up the peep-probe here?' Ross asked.
Ashe's head moved in a slow negative. 'Look farther ... spread out,' the sonic clicked.
Within a matter of minutes the dolphins reported new remains—two more saucers, each larger than the first, set in a line on the ocean floor, pointing directly to Karara's Finger Island. Cautiously explored, these were discovered to be free of any but harmless life; they stirred up no more dragons.
When the Terrans came ashore on Finger Island to rest and eat their midday meal one of the men paced along the beached dragon. Ashore it lost none of its frightening aspect. And seeing it, even beached and dead, Ross wondered at his luck in surviving the encounter without a scratch.
'I think that this one would be alone,' PaKeeKee commented. 'Where there is an eater of this size, there is usually only one.'
'Mano-Nui!' The girl Taema shivered as she gave to this monster the name of the shark demon of her people. 'Such a one is truly king shark in these waters! But why have we not sighted its like before? Tino-rau, Taua ... they have not reported such—'
'Probably because, as PaKeeKee says, these things are rare,' Ashe returned. 'A carnivore of size would have to have a fairly wide hunting range, yet there's evidence that this thing has laired in that den for some time. Which means that it must have a defined hunting territory allowing no trespassing from others of its species.'
Karara nodded. 'Also it may hunt only at intervals, eat heavily, and lie quiet until that meal is digested. There are large snakes on Terra that follow that pattern. Ross was in its front yard when it came after him—'
'From now on'—Ashe swallowed a quarter of fruit—'we know what to watch for, and the weapon which will finish it off. Don't forget that!'
The delicate mechanisms of their sonics had already registered the vibrations which would warn of a dragon's presence, and the depth globes would then do the rest.
'Big skull, oversize for the body.' PaKeeKee squatted on his heels by the head lying on the sand at the end of the now fully extended neck.
Ross had heretofore been more aware of the armament of that head, the fangs set in the powerful jaws, the horn on the snout. But PaKeeKee's comment drew his attention to the fact that the scale-covered skull did dome up above the eye pits in a way to suggest ample brain room. Had the thing been intelligent? Karara put that into words:
'Rule One?' She went over to survey the carcass.
Ross resented her half question, whether it was addressed to him or mere thinking aloud on her part.
Rule One: Conserve native life to the fullest extent. Humanoid form may not be the only evidence of intelligence.
There were the dolphins to prove that point right on Terra. But did Rule One mean that you had to let a monster nibble at you because it might just be a high type of alien intelligence? Let Karara spout Rule One while backed into a crevice under water with that horn stabbing at her mid-section!
'Rule One does not mean to forego self-defense,' Ashe commented mildly. 'This thing is a hunter, and you can't stop to apply recognition techniques when you are being regarded as legitimate prey. If you are the stronger, or an equal, yes—stop and think before becoming aggressive. But in a situation like this—take no chances.'
'Anyway, from now on,' Karara pointed out, 'it could be possible to shock instead of kill.'
'Gordon'—PaKeeKee swung around—'what have we found here—besides this thing?'
