Mac leaned forward and watched with intent eyes. Slowly, like brainless creatures gradually coming to a decision, the endless mob of centaurpedes began moving away. They didn't march, as they had advanced to the attack. They wandered off in the general direction of the sea from which they had sprung.

"I got them," Mac said. He straightened and turned around wearily. "Get in touch with Adonis City, Limpy. Give them the wave length that blankets the queen 'pedes' instructions. Tell them to relay the information to mines that are under siege."

"We've won?" asked Swede incredulously.

"Yes," Mac replied. "And this time it's for good. We'll be able to beat off every attack from now on. Only, I don't think they'll go on fighting much longer. They'll have to quit."

Swede sat down ponderously. "I'm glad, Mac. Not for us; for Al. He didn't die uselessly."

"No," Mac said. "He didn't."

Fumbling with the radio dials, Limpy grinned. None but his close friends could know that grief made his grin wider and more evil-looking than ever.
