On the other hand, suppose they could turn that same gray haze to their own advantage—use it to blanket their withdrawal? He was about to go to Hume with that suggestion when he sighted the new move in their odd battle with the aliens.
A wink of light—two more—blinking, following the erratic course by the pull of the stream. All bobbing along toward the rugged coastline of the islet. Those had appeared out of nothingness as suddenly as the globes when this chase had begun.
The globes and the winking lights on the water connected in his mind, argued new danger. Rynch took careful aim, fired a dart at one which had grounded on the pointed tip of the rocks where the river current came together after its division about the island. For the first time Rynch realized those things below were moving against the current—they had come upstream as if propelled.
He had fired and the light was still there, two more coming in behind it, so that now there was an irregular cluster of them. And there was activity on the water-washed rocks before them. Just as the scavengers had moved ahead of the globes on land, so now aquatic creatures had come out of the river, were flopping higher on the islet. And those lights were changing color—from white to reddish-yellow.
Rynch scrabbled with one hand in a rock crevice, found a stone he had noted earlier. He hurled that at the cluster of lights. There was a puff of brilliant red, one was gone. Something flopping on the rocks gave a mewling cry and somersaulted back into the water. Then a finger of mist drew between Rynch and the lights which were now only faint, glowing patches. He swung down from his perch, shook Hume awake.
The Out-Hunter made that instant return to full consciousness which was another defense for the men who live long on the rim of wild worlds.
“What—?”
Rynch pulled him forward. The mist had thickened, but there were more of those ominous lights at water level, spreading down both sides of the point, forming a wall. Dark forms moved out of the water ahead of them, flopping on the rocks, pressing higher, towards the ledge where the men stood.
“Those globes—I think they’re moving in the river now.” Rynch found another stone, took careful aim, and smashed a second one. “The needler has no effect on them,” he reported. “Stones do—but I don’t know why.”
They searched about them in the crevices for more ammunition, laying up a line of fist-sized rocks, while the lights gathered in, spreading farther and farther down the shores of the islet. Hume cried out suddenly, and aimed his ray tube below. The lance of its blast cut the dark as might a bolt of lightning.
With a shrill squeal, a blot shadow detached from the slope immediately below them. A vile, musky scent, now mingled with the stench of burning flesh, set them coughing.
“Water spider!” Hume identified. “If they are driving those out and up at. …”
He fumbled at his equipment belt and then tossed an object downward to disintegrate in a shower of fiery sparks. Wherever those sparks touched rock or ground they flared up in tall thin columns of fire, lighting up the nightmare on the rocks and up the ledges.
Rynch fired the needler, Hume’s ray tube flashed and flashed again. Things squealed, or grunted, or died silently, while clawing to reach the upper ledges. He could not be sure of the nature of some of those things. One, armed and clawed as the scavengers, was nearly as large as a water-cat. And a furry, man-legged creature, with a double-jawed head, bore also a ring of phosphorescent eyes set in a complete circle about its skull. They were alien life routed out of the water.
“The lights—smash the lights!” Hume ordered.
Rynch understood. The lights had driven these attackers out of the river. Put out the lights and the boiling broth of water dwellers might conceivably return to their homes. He dropped the needler, took up stones and set about the business of finishing off as many of the lights as he could.
Hume fired into the crawling mass, pausing only once to send another of those flame bombs crashing to illuminate the scene. The water creatures bewildered, clumsy out of their element, were so far at his mercy. But their numbers, in spite of the piling dead, were still a dangerous threat.
Rynch tore gapping holes in that line of lights. But he could see, through the mist, more floating sparks, gathering to take their places, perhaps herding before them more water things to attack. Except for those few gaps he had wrought, the islet was now completely enveloped.
“Ahhhh—” Hume’s voice arose in a roar of anger and defiance. He stabbed his ray down at a spot just below their ledge. A huge segmented, taloned leg kicked, caught on the edge of the stone at the level of their feet, twisted aloft again and was gone.
“Up!” Hume ordered. “To the top!”
Rynch caught up two handsful of stones, holding them to his chest with his left arm as he made a last cast to see one light puff out in answer. Then they both scrambled on to that small platform at the top of the islet. By the aid of the burning flame-torches the Hunter had set, they could see that most of the rocky slopes below them now squirmed with a horrible mass of water life.
Where Hume had fired his ray there was fierce activity, as the living feasted on the slain and quarreled over the bounty. But from other quarters the crawling advance pressed on.
“I have only one more flame flare,” Hume stated.
One more flare—then they would be in the dark with the mist hiding the forward-moving enemy.
“I wonder if they are watching out there?” Rynch scowled into the dark.
“They—or what sent them. They know what they are doing.”
“You mean they
