"I see you mean it, Mr. Fort. And—you ought to know that once you've cleared the landing-dock, you'll have a hard time to keep her level unless you're up on the bridge. That is, while you're shifting the wing-angle. But you ought to be down here to do that; and, meanwhile, she might nose down and slam into something, and—" Reblong shuddered.

"I see." The athlete pondered for a moment. Then he lifted the engineer bodily, chair and all, and moved him over nearer the instrument. Next he loosened one of Reblong's hands, just enough to permit him to reach certain of the levers. He also did some more tying of knots and shifting of buckles, roped the chair to a stanchion, and made sure that Reblong could not undo himself.

"It's up to you," said Fort with the new light in his eyes. "You run this thing as it ought to be run, and you're safe. Trick me in any way, and I'll get you!"

Reblong took a single look at those eyes. "I understand," said he, in a low voice; and without further ado the athlete went to the elevator.

In less than a minute the order came to "cast off." The engineer did not hesitate, but threw the levers and turned the wheels which Fort had expected to operate himself. Another second and the great craft was rising from its seat.

Shouts, muffled and faint because of the ship's double windows, sounded from outside. Reblong saw the sheds sinking rapidly below him. In thirty seconds the vessel was free of the dock.

"First gear ahead," came the signal; and again Reblong obeyed. Practically he had no choice. Another man, of nobler training, might have preferred to be loyal at all costs. But Reblong, the representative Capellan workman, saw the lights of the sheds shift slowly to the rear, then go out of sight as the speed increased. He saw one or two fliers preparing to pursue, but he knew that the cruiser would easily outstrip the best of them.

The Cobulus had got clear away!

It was an hour later that the four, this time through the doctor and young Ernol, learned the sequel to Fort's daring feat. The boy was alone in his cell, awake in the darkness, when one of the guards marched up to his door and unlocked it.

"Come out," he ordered; and Ernol preceded him down the corridor, up a flight of stairs, through another corridor and thence into the exercise grounds. On the other side of this was a small building, with no opening save one door, now bright with light. Inside, Ernol found the other men who had been arrested with him, closely watched by a dozen of the prison guards. His father was not there; apparently they were waiting for him to be brought.
