he next morning, as dawn burst over the mountain tops, he started on his perilous mission. But no one who knew Hilary Grendon would have recognized him in the meek, shambling, slightly bent Earth slave who climbed the last rung of the rope ladder out of the hidden gorge.

He had changed his clothes for an old, space-worn suit that one of his former comrades could never have any further use for. The skilful application of wood ash and powdered charcoal to the hollows around the eyes, the pits beneath the cheekbones, gave him a gaunt, careworn appearance, suitable to an Earthman too brow-beaten to dream of defying his overlords.

Wat, who had artistically applied the make-up, viewed his handiwork with admiration. "You'll do," he grinned. "The way you look, even a little fellow like me would be perfectly safe in spitting upon you."

Before he went, he explained the mechanism of the Vagabond thoroughly to his friends. Finally they nodded; they would know how to work the controls.

There was the question of weapons. The captured sun-tube was out of the question; it could not be secreted beneath the dark-blue blouse. Hilary fondled his automatic wistfully.

"If only I had some bullets," he sighed.

"Hell, man, I know where you can get plenty," said Wat. There was a hidden cache, not far from where they were, stored against the day. There were still some brave spirits left on Earth who hoped and plotted. Wat had been one of them. Hilary's spirits rose immeasurably. With his gun loaded he could face the whole Mercutian planet.
