"Presently as I stood staring down at the liquid that must have poured from the wounds I had inflicted upon Abaris, I heard a terrific roar coming from somewhere near. The floor of the chamber rolled like the surface of an angry sea. I was dashed against the wall where I lay. I expected momentarily to see the chamber close up and crush me to death, sealing me in a living tomb deep beneath the Manalava Plain! "There came a terrific, thunderous crash, the impact of which caused me to rise from the ground and fall again yards away! With the crash came the blinding flash of some terrible explosion. A great, hissing sound reached my ears and then I heard a loud, ear-splitting shriek. I looked overhead at the fissure in the earth through which filtered the soul-gladdening sunlight. I caught a glimpse of a great sphere travelling at a terrific speed into the sky! As it sped away, the shriek of its passing became less discernible and soon died out altogether. The Jovians had departed for their own planet, taking Allie Lane, her father and Driftin' Sands with them! Gradually the earth roar ceased and with it ceased the earth's heaving. "I stared around me now able to see the entire chamber. Not an object remained in it--not a fragment of any of the beautiful purple and gold drapes that had decorated the room which had been Allie Lane's. The Jovians had removed every object while I lay on the floor, apparently dead. Abaris' ray could not have struck me squarely, or else he had been too feeble and weak as the result of his wounds, to do more than stun me temporarily. In my rapid search of the room I discovered that the upheaval caused by the departure of the great interplanetary traveler, had sealed the tunnel in which I had hidden during the conflict between Sands and Abaris. The tunnel through which Abaris had suddenly appeared was likewise closed with massive rocks. "As a last resort to escape from the underground world I began to study the possibility of crawling to the surface of the Manalava Plain through the wide fissure overhead. The opening was too high for me to reach up and obtain enough of a handhold to support my weight. I spent hours, working constantly, piling some of the broken rocks from the tunnels under the fissure. Eventually I succeeded in grasping a sharp rock protruding from the side of the crevice and hoisted myself up. It was hard, that climb to the outer world. "Presently after what seemed hours of back-breaking labor I reached the surface. How good it was to breathe the pure air of Death Valley again! The atmosphere, in spite of the terrific heat of the Manalava Plain, was sweet and beautiful. My lungs, long since taxed with the foul, nauseating atmosphere of the tunnels and caverns deep below me, pumped madly, as I breathed in the delightful air of my own world!
