"It's beyond me," the Ace Commander said hopelessly.
Professor Grant was speaking to Cartography.
"Jupiter VIII, second arc of sector. Thank you, Sidbee. Flash Challenge Queen telling her to proceed there at once and to clear all space stations, pending further instructions. Note for Operation Elemental: all minnows to be overhauled and in readiness for instant launching. Good."
He turned to Dr. Walstab. He said: "I'm doing what I can, but I say frankly I don't see how we're to get Sommers, so to speak, into the open. I'll say this, too—win or lose, this I.G. of yours, "Walstab, has at least made it possible for us to contact and perhaps comfort the poor fellow. He'll know our thoughts are with him . . ."

Yet, maybe they did. Maybe, although the light remained the same, there were intervals in which they rested. At any rate, there was no sign of any life on the great landing field. The queer-looking ship had vanished. The hangar door was closed. There were a few small craft resting on speedways, whose design he couldn't make out, but otherwise the place was deserted. Asleep. The idea persisted. And with it came a second idea, an exciting idea. Now was his chance to get out of this place—this building, anyhow. Maybe, if he could get hold of one of those parked m.ichines, he could fly it out . . . But he gavo-that up at once. He was convinced now that all this was no dream. So long as his vibrations held up, he was imprisoned in Elemental.
But the thought led on. He was beginning to find the answer to some things at least. The talk be-
