orman, mind and body strained to the breaking point, was incoherent. "We guessed how you'd gone—the second satellite, Fellows—Hackett and I came after you—taken to that frog-city—"

As Norman choked the tale, Fellows' face was a study. And when it was finished he swallowed, and gripped Norman's hand viselike.

"And you and Hackett figured it out and came after me—took that risk? Crazy, both of you. Crazy—"

"Fellows, Hackett's still there, if he's alive! In the Rala city!"

Fellows' voice was grim, quick. "We'll have him out. Norman, if he still lives. And living or dead, the Ralas will pay soon for this and for all they've done upon this world in ages. Their time nears—yes."

He led Norman, excited throngs of the green men about them, into the great building from which he had emerged. There were big rooms inside, workshops and laboratories that Norman but vaguely glimpsed in passing. The room to which the other led him was one with a long metal couch. Norman stretched protestingly upon it at the other's bidding, drifted off almost at once into sleep.

He woke to find the sunlight that had filled the room gone and replaced by the silvery Earth-light. From the window he saw that the silver-lit city outside now held tremendous activity, immense hordes of green men surging through it with masses of weapons and equipment, flying-boats pouring down out of the night from all directions. He turned as the door of the room clicked open behind him. It was his old friend Fellows.

"I thought you'd be awake by now, Norman. Feeling fit?"

"As though I'd slept a week," Norman said, and the other laughed his old care-free laugh.

"You almost have, at that. Two days and nights you've slept, but it all adds up to hardly more than a dozen hours."
