"They will kill us," said Tar-gash. "If you were not a gilak, we might escape through the trees, but as you cannot escape we shall have to remain and fight." "Lead the way," said Tarzan, "There is no Sagoth trail that Tarzan cannot follow." "Come then," said Tar-gash, and as he spoke he hurled his club into the faces of the oncoming warriors and, turning, fled along the trail. A dozen mighty bounds he took and then leaped to the branch of an overhanging tree, and close behind him came the hairless gilak. M'wa-lot's hairy warrior bulls pursued the two for a short distance and then gave up the chase as Tarzan was confident that they would, since among his own people it had usually been considered sufficient to run a recalcitrant bull out of the tribe and, unless he insisted upon returning, no particular effort was made to molest him. As soon as it became evident that pursuit had been abandoned the Sagoth halted among the branches of a huge tree. "I am Tar-gash," he said, as Tarzan stopped near him. "I am Tarzan," replied the ape-man. "Why did you warn me?" asked Tar-gash. "I told you that I did not come among you as an enemy," replied Tarzan, "and when I saw that To-yad had succeeded in urging M'wa-lot to kill you, I warned you because it was you that kept the bulls from killing me when I was captured." "What were you doing in the country of the Sagoths?" asked Tar-gash. "I was hunting," replied Tarzan. "Where do you want to go now?" asked the Sagoth. "I shall return to my people," replied Tarzan. "Where are they?" Tarzan of the Apes hesitated. He looked upward toward the sun, whose rays were filtering down through the foliage of the forest. He looked about him--everywhere was foliage. There was nothing in the foliage nor upon the boles or branches of the trees to indicate direction, Tarzan of the Apes was lost! V BROUGHT DOWN Jason Gridley, looking down from the branches of the tree in which he had found sanctuary, was held by a certain horrible fascination as he watched the feast of the great cats. The scene that he had just witnessed--this stupendous spectacle of savagery--suggested to him something of what life upon the outer crust must have been at the dawn of humanity. The suggestion was borne in upon him that perhaps this scene which he had witnessed might illustrate an important cause of the extinction of all of these animals upon the outer crust. The action of the great saber-tooth tigers of Pellucidar in rounding up the other beasts of the forest and driving them to this clearing for slaughter evidenced a development of intelligence far beyond that attained by the carnivores of the outer world of the present day, such concerted action by any great number for the common good being unknown.
