he urgent toil of the pirates was showing results. By the time night came again, and the meteor-moonlets blazed forth with magic beauty in the dark heavens, the task of repair was almost done. Kenniston and his companions had not ventured forth from the hut. Pirates were everywhere in the clearing, and all had heard John Dark's strict order to blast down the captives if they left their prison. But from the hut, Kenniston and the others could see that the horde of Vestan-dominated animals around the camp had further increased. With ghastly avidity, they kept circling the shimmering, electric wall. Kenniston turned in alarm at a ripping sound from the back of the log hut. Two of the logs were being torn out bodily.

"Why do you tell us this, Holk? You're one of the pirates yourself." "I know, but I'm afraid Dark means to drop me with the others by the Sunsprite!" Holk Or exclaimed. "He didn't say so, but I believe
