At the edge floated the limp, dead thing that Mara had killed to save Planter. Small flutterers, like gross-winged flies but as large as gulls, swarmed to dig out morsels. Mara called the creature a krau, the flying scavengers ghrols. "Skygor words, for ugly beasts," she commented. "Neither is good for food." Planter picked his way from root to root toward the ship. "Disbro!" he called. "Max!" There was no answer. He scrambled up and inside, then out again. "Something's happened," he said gravely. Mara studied the massed logs that made a rough raft. "Skygor work. And eke the rope of wires about your ship." "They've been captured by Skygors? For slaves?" Planter had climbed down again.

She slipped aside through the close-set stems. Planter did likewise. Mara slung her crossbow behind her, and climbed a trunk as a beetle scales a flower-stalk. "'Tis safer from Skygors up here," she told him over her shoulder "Follow me carefully." Planter did so, with difficulty. He was a vigorous climber, and the lesser gravity of Venus made him more agile. But Mara, some forty feet overhead,
