them in the thin sunlight rose slender trees whose enormous green leaves grew directly from the trunks. This grotesque forest was made more dense by festoons of writhing "snake-vines," weird rootless creepers which crawled like plant-serpents from one tree to another. Each stir of wind brought white spore-dust down in a shower from the trees. The few living creatures of this forbidding landscape were equally alien. Big white meteor-rats scurried on their eight legs through the brush. Phosphorescent flame-birds shot through the upper fronds like streaks of fire. In the pale sky overhead, there were ceaseless gleams and flashes of light as the spinning meteor-swarm reflected the sunlight. "What a horrible place!" shrilled Mrs. Milsom. "We'll all die here—we'll never get back to Earth. I knew this would happen!" "This is certainly a mean spot to be cast away," muttered Captain Walls.

And the telaudio wrecked, so we can't call for help." Kenniston realized that none of the others had glimpsed Dark's camp as they fell.

Bray and the crew and I ought to be able to do an emergency job of patching the bow and installing new rocket-tubes there. But we'll have to work fast to get away before Dark's outfit learns we're here." He pointed vindicatively at Kenniston. "Better lock up that fellow and his partner to make sure he doesn't signal somehow to his fellow-pirates." Kenniston tried again to explain. "Will you all listen to me? I tell you, I'm no pirate!" Murdock eyed him sternly. "Do you deny that John Dark sent you to Mars for repair-equipment,
