Forepaugh put his hand to his head. It made him dizzy. He had not believed that such noise could be. He knew that no creature could long live amidst it. He tore strips from his shredded clothing and stuffed his ears, but felt no relief. "HOOM! HOOM! HOOM! HOOM! HOOM!" It throbbed in his brain. Gunga lay a-sprawl, staring with fascinated eye into the pulsating scarlet gullet that was blasting the world with sound. Slowly, slowly he was slipping. His master hauled him back. The Martian grinned at him stupidly, slid again to the edge. Once more Forepaugh pulled him back. The Martian seemed to acquiesce. His single eye closed to a mere slit. He moved to a position between Forepaugh and the tree trunk, braced his feet. "No you don't!" The Earth man laughed uproariously. The din was making him light-headed. It was so funny! Just in time he had caught that cunning expression and prepared for the outlashing of feet designed to plunge him into the red cavern below and to stop that hellish racket. "And now--" He swung his fist heavily, slamming the Martian against the tree. The red eye closed wearily. He was unconscious, and lucky. Hungrily the Earth man stared at his distant flash pistols, plainly visible in the luminescence of their fungus bedding. He began a slow, cautious creep along the top of a vine some eight inches thick. If he could reach them.... * * * * * Crash! He was almost knocked to the ground by the thud of a frantic tentacle against the vine. His movement had been seen. Again the tentacle struck with crushing force. The great vine swayed. He managed to reach the shelf again in the very nick of time. "HOOM! HOOM! HOOM! HOOM! HOOM!" A bolt of lightning struck a giant fern some distance away. The crash of thunder was hardly noticeable. Forepaugh wondered if his tree would be struck. Perhaps it might even start a fire, giving him a flaming brand with which to torment his tormentor. Vain hope! The wood was saturated with moisture. Even the fire pellets could not make it burn. "HOOM! HOOM! HOOM! HOOM! HOOM! HOOM! HOOM!" The six-shooter! He had forgotten it. He jerked it from its holster and pointed it at the red throat, emptied all the chambers. He saw the flash of yellow flame, felt the recoil, but the sound of the discharges was drowned in the Brobdignagian tumult. He drew back his arm to throw the useless toy from him. But again that unexplainable, senseless "hunch" restrained him. He reloaded the gun and returned it to its holster. "HOOM! HOOM! HOOM! HOOM! HOOM! HOOM!"
