"Let's go," said Cochrane.

He noted with surprise that his mouth was suddenly dry. This affair was out of all reason. A producer of television shows should not be the person to discover in an abstruse scientific development the way to reach the stars. A neurotic son-in-law of an advertising tycoon should not be the instrument by which the discovery should come about. A psychiatrist should not be the means of associating Jones—a very junior physicist with no money—and Cochrane and the things Cochrane was prepared to bring about if only this unlikely-looking gadget worked.

Jones pointed there in the shadow of the crater-wall, and Babs moved to the switch he indicated. She said absorbedly:

"Five, four, three, two, one—"

She threw the switch. There was a spout of lurid red flame.

The rocket vanished.

It vanished. It did not rise, visibly. It simply went away from where it was, with all the abruptness of a light going out. There was a flurry of the most brilliant imaginable carmine flame. That light remained. But the rocket did not so much rise as disappear.

Cochrane jerked his head up. He was close to the line of the rocket's ascent. He could see a trail of red sparks which stretched to invisibility. It was an extraordinarily thin line. The separate flecks of crimson light which comprised it were distant in space. They were so far from each other that the signal-rocket was a complete failure as a device making a streak of light that should be visible.

The muffled voice in the helmet-phones said blankly:
