had swarmed out into its streets with the passing of the
alarm, and their craft and the others came to rest in an open square
that was the juncture of several streets.

The green men that crowded excitedly about Norman and Sarja gave way
to a half-dozen hurrying into the square from the greatest of the
buildings facing on it. All but one were green men like the others.
But that one--the laughing-eyed tanned face--the worn brown clothing,
the curious huge steps with which he came--Norman's heart leapt.

"Fellows!"

"Great God--Norman!" The other's face was thunderstruck. "Norman--how
by all that's holy did you get here?"

Norman, 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?

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."

"Thi
