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
