the rippling, rustling sound that came from everywhere in the cavern. The black surface of the lake was dotted now with spots of burning phosphorescent color, trailing fiery wakes. The spots grew swiftly, coming nearer, and became carpets of flowers, scarlet and blue and gold and purple. Floating fields of them, and towed by shining swimmers. "My God," said Harker softly. "How big are they?" "Enough to make three of me." Sim was a big man. "Those little ones were children, all right. They went and got their papas. Oh, Lord!"

McLaren's foot was swollen, the calf of his leg discolored. Some swift infection from the planny's claws. He fought Harker. "Go on," he said. "Go on!" Harker slapped him hard across the temple. He started on, half carrying
