Insensibly both sides drew apart, leaving a space between Tatar and Apache. The faces of the Amerindians were grim, those of the Mongols bewildered and then harsh as they eyed their late opponents with dawning reason. What had begun in compulsion for the Tatars might well flare now into rational combat--and from that to a campaign of extermination. Travis was on his feet. He looked over the lip of the drop. The Red was still in his place down there, a pile of rubble about him. His protection must have failed, for his head was back at an unnatural angle and the dent in his helmet could be easily seen. "That one is dead--or helpless!" Travis cried out. "Do you still wish to fight for him, Shaman?" Menlik came away from the tree and walked to the edge of the drop. The others, too, were moving forward. After the shaman looked down he stooped, picked up a small stone, and flung it at the motionless Red. There was a crack of sound. They all saw the tiny spurt of flame, a curl of smoke from the plate on the Red's chest. Not only the man, but his control was finished now. A wolfish growl and two of the Tatars swung over, started down to the Red. Menlik shouted and they slackened pace. "We want that," he cried in English. "Perhaps so we can learn--" "The learning is yours," Jil-Lee replied. "Just as this land is yours, Shaman. But I warn you, from this day do not ride south!" Menlik turned, the charms on his belt clicking. "So that is the way it is to be, Apache?" "That is the way it shall be, Tatar! We do not ride to war with allies who may turn their knives against our backs because they are slaves to a machine the enemy controls." The Tatar's long, slender-fingered hands opened and closed. "You are a wise man, Apache, but sometimes more than wisdom alone is needed----" "We are wise men, Shaman, let it rest there," Jil-Lee replied somberly. Already the Apaches were on their way, putting two cliff ridges behind them before they halted to examine and cover their wounds. "We go." Nolan's chin lifted, indicating the southern route. "Here we do not come again; there is too much witchcraft in this place." Travis stirred, saw that Jil-Lee was frowning at him. "Go--?" he repeated. "Yes, younger brother? You would continue to run with these who are governed by a machine?" "No. Only, eyes are needed on this side of the mountains." "Why?" This time Jil-Lee was plainly on the side of the conservatives. "We have now seen this machine at work. It is fortunate that the Red is dead. He will carry no tales of us back to his people as you feared. Thus, if we remain south from now on, we are safe. And this fight between Tatar and Red is none of ours. What do you seek here?" "I must go again to the place of the towers," Travis answered with the truth. But his friends were facing him with heavy disapproval--now a full row of Deklays.
