"That is all," he concluded.

"O.Q.," verified the other radioman. Isobar writhed anxiously, prodded Riley's shoulder.

"Ask him, Sparks! Go on ask him!"

"Oh, cut jets, will you?" snapped Sparks. The Terra operator looked startled.

"How's that? I didn't say a word—"

"Don't be a dope," said Sparks, "you dope! I wasn't talking to you. I'm entertaining a visitor, a refugee from a cuckoo clock. Look, do me a favor, chum? Can you twist your mike around so it's pointing out a window?"

"What? Why—why, yes, but—"

"Without buts," said Sparks grumpily. "Yours not to reason why; yours but to do or don't. Will you do it?"

"Well, sure. But I don't understand—" The silver platter which had mirrored the radioman's face clouded as the Earth operator twirled the inconoscope. Walls and desks of an ordinary broadcasting office spun briefly into view; then the plate reflected a glimpse of an Earthly landscape. Soft blue sky warmed by an atmosphere-shielded sun ... green trees firmly rooted in still-greener grass ... flowers ... birds ... people....

"Enough?" asked Sparks.
