"My _Tao_ is strong," he said, and went on with whatever fantastic thoughts came into his mind. He was talking against time. He told of the new world his _Tao_ had built, of men harnessing the lightning and flying through the air; of cannon that roared like the thunder and threw death and destruction upon those that the _Tao_ would destroy.... And his eyes watched the slow descent of the dropping sun, while the figure above stirred impatiently and raised his spear. "A sign!" Luhra was imploring. "He does not believe!" The golden ball was touching now on a distant, purple peak. The amazing magic of the desert!--its moment had come! Garry indicated as best he could the phantom sea, so real, below. "My _Tao_ has spoken," he shouted: "watch! The waters shall be dried up; the seas shall become a desert of hot sand; the lands and waters that Horab knows shall be no more! There shall be no food for his stomach nor water for his lips where Horab wanders in torment.... Unless I save him." * * * * * He turned to stare at the vast mirage. He knew that the eyes of the others had followed his, and he knew that they saw the first change that crept over the land. The blue that was so unmistakably a sea was dissolving; it seemed sucked into the sand. And, while yet the hot rays cast their lingering gold over mountain and plain, the seas faded and were gone ... and where they had been in unquestioned reality was only yellow sand that whirled hotly and drifted in the first breath of the coming night.... The towering figure above them stood rigid. Garry had found a sharp edge of rock, and sawed frantically upon it to cut the soft gold of the cords at his wrists. The one above them paid no heed; his eyes were held in horror of this silent death that swept across the world. The hand that Garry extended was steady and cautious; his arm crept about the body of white and gold to draw the amazed and wondering girl silently into the open cave. "Follow!" he ordered, and dashed headlong down the darkened way where an automatic was waiting for his eager fingers. The pack was there, and he tore at it with frenzied hands to grip at the pistol within. And there was also an open chest whose contents glittered in the green light, and whose weight was not too great for him to carry.... He had both chest and gun when he returned. The stumbling falls in his mad rush had not served to allay the hurts of his tortured body, nor still his raging fury. He called to Luhra as he ran--and realized that Luhra was gone. The chest fell forgotten at his feet as he rushed out; he shouted her name and cursed himself for leaving her. * * * * * Had the fascination of the outer world drawn her back? Had she trusted too greatly in the power of his Tao to shield her from harm? Connell could not know. He knew only that he saw her struggling in the grip of the long arms where the black one held her on an outthrust rock.
