Ska, perched upon the horn of dead Gorgo, became suddenly aware of a movement in a nearby thicket. He turned his head in the direction of the sound and saw Sabor the lioness emerge from the foliage and walk slowly toward him. Ska was not terrified. He would leave, but he would leave with dignity. He crouched to spring upward, and extended his great wings to aid him in taking off. But Ska, the vulture, never rose. As he essayed to do so, something pulled suddenly upon his neck and held him down. He scrambled to his feet and, violently this time, strove to fly away. Again he was dragged back. Now Ska was terrified. The hateful thing that had been dangling about his neck for so long was holding him to earth--the swinging loop of the golden chain had caught around the horn of Gorgo, the buffalo. Ska was trapped. He struggled, beating his wings. Sabor stopped to regard him and his wild antics. Ska was flopping around in a most surprising manner. Sabor had never seen Ska behave thus before, and lions are sensitive, temperamental animals; so Sabor was not surprised only, she was inclined to be frightened. For another moment she watched the unaccountable antics of Ska and then she turned tail and slunk back into the undergrowth, turning an occasional growling countenance back upon the vulture, as much as to say; "Pursue me at your peril!" But Ska had no thought of pursuing Sabor. Never again would Ska, the vulture, pursue aught. "They are coming!" announced Komodoflorensal, prince of Trohanadalmakus. As Tarzan looked out across the rolling country in the direction of the enemy, he presently saw, from his greater height, the advance of the Veltopismakusians. "Our scouts are falling back," he announced to Komodoflorensal. "You can see the enemy?" demanded the prince. "Yes." "Keep me advised as to their movements." "They are advancing in several long lines, deployed over a considerable front," reported the ape-man. "The scouts are falling back upon the outpost which seems to be standing its ground to receive them. It will be overwhelmed--if not by the first line then by those that succeed it." Komodoflorensal gave a short command. A thousand mounted men leaped forward, urging their diadets into bounding leaps that cleared five, six and even seven feet at a time. Straight for the outpost ahead of them they raced, deploying as they went. Another thousand moved quickly toward the right and a third toward the left of the advance cavalry's position following Tarzan's announcement that the enemy had divided into two bodies just before it engaged the outpost, and that one of these was moving as though with the intention of turning the right flank of the main cavalry of Trohanadalmakus, while the other circled in the direction of the left flank. "They are striking boldly and quickly for prisoners," said the prince to Tarzan.
