prisoners. With a strong escort of armed pirates guarding them, and Dark and Holk Or ahead, they started through the jungle toward the pirate camp. CHAPTER VI Asteroid Horror he pirate encampment was a big clearing hacked from the jungle a mile west of the little lake. In this space lay the long, looming black mass of the most dreaded corsair ship ever to sail the void. The Falcon had been righted to even keel, but its crippled condition was evident in the fused, wrecked condition of its tail rocket-tubes. The whole camp was enclosed and protected by a shimmering blue dome of electric force. This emanated from a heavy copper cable that completely encircled the clearing, and which drew its power from insulated cables that led into the ship to generators driven by the few cyclotrons still functioning. This protective electric wall had been set up at John Dark's orders to keep out the dreaded Vestans. John Dark raised his voice as he and his men with their prisoners approached the shimmering wall of the camp. "Kin Ibo! Drop the wall for us!" They saw the hard-looking Martian who was Dark's second-in-command dive into the ship to turn off the power of the electric barrier. It died, and Dark's party entered the clearing. Then the electric wall sprang into being again behind them. Kenniston looked swiftly around. There were a score more of the motley pirates here in the camp. Also, near the side of the looming black Falcon, were the small, rough log huts that Dark's men had constructed. Dark's black eyes were triumphant as he told his Martian lieutenant, "Kenniston and Holk Or brought back the equipment all right, and also brought some people who'll bring big ransom. Their wrecked ship is a few miles south. You go down there with half the men here and help the others bring up the equipment." Kin Ibo, looking a little apprehensively out at the jungle, obeyed. Dark motioned Kenniston and the other captives toward one of the huts by the big ship. "That hut will be your quarters until we get the Falcon repaired," declared the pirate leader. "Any of you who try to leave it will be shot at sight. I hope you'll not be foolish enough to attempt escape." "That's right, folks, you wouldn't have a chance,"
