Key Out of Time Part 2

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 ash.o.r.e 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 b.u.t.t 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 ash.o.r.e on Finger Island to rest and eat their midday meal one of the men paced along the beached dragon. Ash.o.r.e 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 trespa.s.sing 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 carca.s.s.

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?"

"I can't even guess. Except that those depressions were made for a purpose and have been there for a long time. Whether they were originally in the water, or the land sank, that we don't know either.

But now we have a site to set up the peep-probe."

"We do that right away?" Ross wanted to know. Impatience bit at him. But Ashe still had a trace of frown. He shook his head.

"Have to make sure of our site, very sure. I don't want to start any chain reaction on the other side of the time wall."

And he was right, Ross was forced to admit, remembering what had happened when the galactics had discovered the Red time gates and traced them forward to their twentieth-century source, ruthlessly destroying each station. The original colonists of Hawaika had been as giants to Terran pygmies when it came to technical knowledge. To use even a peep-probe indiscreetly near one of their outposts might bring swift and terrible retribution.

The Ancient Mariners

Another map spread out and this time pinned down with small stones on beach gravel.

"Here, here, and here--" Ashe's finger indicated the points marked in a pattern which flared out from three sides of Finger Island. Each marked a set of three undersea depressions in perfect alliance with the land which, according to the galactic map, had once been a cape on a much larger land ma.s.s. Though the Terrans had found the ruins, if those saucers in the sea could be so termed, the remains had no meaning for the explorers.

"Do we set up here?" Ross asked. "If we could just get a report to send back...." That might mean the difference between awakening the co-operation of the Project policy makers so that a flood of supplies and personnel would begin to head their way.

"We set up here," Ashe decided.

He had selected a point between two of the lines where a reef would provide them with a secure base. And once that decision was made, the Terrans went into action.

Two days to go, to install the peep-probe and take some shots before the ship had to clear with or without their evidence. Together Ross and Ashe floated the installation out to the reef, Ui and Karara helping to tow the equipment and parts, the dolphins lending pushing noses on occasion.

The aquatic mammals were as interested as the human beings they aided.

And in water their help was invaluable. Had dolphins developed hands, Ross wondered fleetingly, would they have long ago wrested control of their native world--or at least of its seas--from the human kind?

All the human beings worked with practiced ease, even while masked and submerged, to set the probe in place, aiming it landward at the check point of the Finger's protruding nail of rock. After Ashe made the final adjustments, tested each and every part of the a.s.sembly, he gestured them in.

Karara's swift hand movement asked a question, and Ashe's sonic code-clicked in reply: "At twilight."

Yes, dusk was the proper time for using a peep-probe. To see without risk of being sighted in return was their safeguard. Here Ashe had no historical data to guide him. Their search for the former inhabitants might be a long drawn-out process skipping across centuries as the machine was adjusted to Terran time eras.

"When were they here?" Back on sh.o.r.e Karara shook out her hair, spread it over her shoulders to dry. "How many hundred years back will the probe return?"

"More likely thousands," Ross commented. "Where will you start, Gordon?"

Ashe brushed sand from the page of the notebook he had steadied against one bent knee and gazed out at the reef where they had set the probe.

"Ten thousand years--"
