“Kar Komak!” he cried. “Why cannot you do what Tario and Jav did? They had no bowmen other than those of their own creation. You must know the secret of their power. Call forth your own utan, Kar Komak!” The Lotharian looked at Carthoris in wide-eyed astonishment as the full purport of the suggestion bore in upon his understanding. “Why not?” he murmured. The savage ape bearing the mighty bludgeon was slinking toward Carthoris. The Heliumite’s fingers were working as he kept his eyes upon his executioner. Kar Komak bent his gaze penetratingly upon the apes. The effort of his mind was evidenced in the sweat upon his contracted brows. The creature that was to slay the red man was almost within arm’s reach of his prey when Carthoris heard a hoarse shout from the opposite side of the courtyard. In common with the squatting apes and the demon with the club he turned in the direction of the sound, to see a company of sturdy bowmen rushing from the doorway of a near-by building. With screams of rage the apes leaped to their feet to meet the charge. A volley of arrows met them half-way, sending a dozen rolling lifeless to the ground. Then the apes closed with their adversaries. All their attention was occupied by the attackers—even the guard had deserted the prisoners to join in the battle. “Come!” whispered Kar Komak. “Now may we escape while their attention is diverted from us by my bowmen.” “And leave those brave fellows leaderless?” cried Carthoris, whose loyal nature revolted at the merest suggestion of such a thing. Kar Komak laughed. “You forget,” he said, “that they are but thin air—figments of my brain. They will vanish, unscathed, when we have no further need for them. Praised be your first ancestor, redman, that you thought of this chance in time! It would never have occurred to me to imagine that I might wield the same power that brought me into existence.” “You are right,” said Carthoris. “Still, I hate to leave them, though there is naught else to do,” and so the two turned from the courtyard, and making their way into one of the broad avenues, crept stealthily in the shadows of the building toward the great central plaza upon which were the buildings occupied by the green warriors when they visited the deserted city. When they had come to the plaza’s edge Carthoris halted. “Wait here,” he whispered. “I go to fetch thoats, since on foot we may never hope to escape the clutches of these green fiends.” To reach the courtyard where the thoats were kept it was necessary for Carthoris to pass through one of the buildings which surrounded the square. Which were occupied and which not he could not even guess, so he was compelled to take considerable chances to gain the enclosure in which he could hear the restless beasts squealing and quarrelling among themselves.
