"Meaning, as I take it, that there is time required for the message to go from the ship to the station and for them to reply."

"An appreciable time like that," Captain Blake exclaimed, "—with radio! Why, a few seconds, even, would carry it around the world a score of times!"

Lieutenant McGuire hesitated a moment. "It happens every time," he reminded the captain: "it is no coincidence. And if that other station is out in space—another ship perhaps, relaying the messages to yet others between here and—Venus, let us say...."


e left the thought unfinished. Captain Blake was staring at him as one who beholds a fellow-man suddenly insane. But the look in his eyes changed slowly, and his lips that had been opened in remonstrance came gradually in a firm, straight line.

"Crazy!" he said, but it was apparent that he was speaking as much to himself as to McGuire. "Plumb, raving crazy!... Yet that ship did go straight up out of sight—an acceleration in the upper air beyond anything we know. It might be—" And he, too, stopped at the actual voicing of the wild surmise. He shook his head sharply as if to rid it of intruding, unwelcome thoughts.

"Forget that!" he told McGuire, and repeated it in a less commanding tone. "Forget it, Mac: we've got to render a report to sane men, you and I. What we know will be hard enough for them to believe without any wild guesses.

"That new craft is real. It has got it all over us for size and speed and potential offensive action. Who made it? Who mans it? Red Russia? Japan? That's what the brass hats will be wondering; that's what they will want to find out.

"Not a word!" he repeated to the radio man. "You will keep mum on this."
