Darl leaped to his feet. Before the astounded natives realized what was up he was charging into their circle. A well aimed kick sent one crashing against the further wall. Another crunched against the rock. Then they were on him, a frothing wave of tiny furies. A score or more, they swarmed over him as a pack of African wild dogs swarms over a huge water-buffalo marked for the kill. Their claws scratched and tore, their sharp fangs stabbed into his flesh. His arms were still tightly bound to his sides, and he lashed out with his sandaled feet, swung his shoulders like battering rams, whirled in a dervish dance. Their brittle bones cracked under his hammer blows. They dropped from him like squashed flies. But, small as they were, he was terrifically outnumbered. By sheer weight of numbers they dragged him down, and piled on top of him as he lay, quivering and half-conscious, on the blood-soaked floor. * * * * * Through the blackness that welled and burst in his brain, one thought held. He had fooled the Martian, for in another instant the enraged savages, would kill him and the password to Earth's outposts would be safe. Already, he felt their fangs at his throat. A whirring rattle cut through the turmoil like a whip-lash, and the heap of pigmies swiftly scattered. The man-bird from Mars was in the room. To Darl he was a blurred blueness from which glittered those two jet beads of eyes. As from a distance he heard a rumble, its meaning beating dully to him. "Not so easy, Thomas, not so easy. I want that signal, and by Tana, I'm going to have it." The Earthman felt a current of cooler air. Instinctively he drew it into his lungs. It swept him up from the blackness that was closing in about him, brought him back to consciousness and despair. The chattering Mercurians crowded round to commence their interrupted orgy. "For the last time, Earthman, will you talk?" Darl shook his head weakly and closed his eyes. In a moment-- Suddenly there was a crash of metal on metal. Another! The clangor of falling steel. Now someone was shouting, "Darl, Darl, are you alive?" All about him were shrill twitterings, squeaking calls, squeals and scutterings. Darl's nostrils stung with the odor of burned flesh. A door slammed.... He opened his eyes on a confused riot, saw Jim crouched, flashing ray-gun in hand. There was a hole in the barrier, and a mob of green-scaled Venusians were crowding through. Jim's ray caught the last Mercurian and the dwarf vanished in a cloud of acrid, greasy smoke. "Thank God you've come!" Darl managed to gasp. Then cool blackness closed around him. * * * * *
