"So?" said Koal.

"So," said Norman. "I think that if a little group of patriots like the Sinn Feiners could throw off the yoke of the British Empire, we should be able to turn the tables on the Dohlmites."

"I've seen rebellions before," began Koal stonily.

"I know. But Koal, I'm not proposing any premature mutiny. I do believe, though, we should band together secretly. If any opportunity for escape presents itself, we'll be ready for it; not just a disunited group of clans snapping at each other's throats."

The Martian appeared to waver.

"Koal," Norman went on urgently. "Only one thing stands between us and freedom. The death broadcasting machine."

"Yes, just that—and a force wall impossible to penetrate."

"What maintains the force wall?" asked Norman.

The Martian shook his head.

"Suppose we succeed in neutralizing it. We'd have a picked body of men to rush the Dohlmite station, destroy the cylinders."
