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.
