"I am your friend," replied the youth; "that is why I am here, but you would never live to cross the ledge to the trail, there are too many warriors and they are all prepared. They know that you are armed and they expect that you will try to escape." "There is no other way," said Tarzan. "There is another way," replied the boy, "and I have come to show it to you." "Where?" asked Jana. "Follow me," replied Ovan, and he started back into the remote recesses of the cavern, which were fitfully illumined by his flickering torch, while behind him followed Jana and the ape-man. The walls of the cavern narrowed, the floor rose steeply ahead of them, so that in places it was only with considerable difficulty that they ascended in the semi-darkness. At last Ovan halted and held his torch high above his head, revealing a small, natural chamber, at the far end of which there was a dark fissure. "In that dark hole," he said, "lies a trail that leads to the summit of the mountains. Only the chief and the chief's first son ever know of this trail. If my father learns that I have shown it to you, he will have to kill me, but he shall never know for when next they find me I shall be asleep upon a skin in the cavern far below. The trail is steep and rough, but it is the only way. Go now. This is the return I make you for having saved my life." With that he dashed the torch to the floor, leaving them in utter darkness. He did not speak again, but Tarzan heard the soft falls of his sandaled feet groping their way back down toward the cavern of the Clovi. The ape-man reached out through the darkness and found Jana's hand. Carefully he led her through the stygian darkness toward the mouth of the fissure. Feeling his way step by step, groping forward with his free hand, the ape-man finally discovered the entrance to the trail. Clambering upward over broken masses of jagged granite through utter darkness, it seemed to the two fugitives that they made no progress whatever. If time could be measured by muscular effort and physical discomfort, the two might have guessed that they passed an eternity in this black fissure, but at length the darkness lessened and they knew that they were approaching the opening in the summit of the mountains; nor was it long thereafter before they emerged into the brilliant light of the noonday sun. "And now," said Tarzan, "in which direction lies Zoram?" The girl pointed. "But we cannot reach it by going back that way," she said, "for every trail will be guarded by Carb and his fellows. Do not think that they will let us escape so easily. Perhaps in searching for us they may even find the fissure and follow us here." "This is your world," said Tarzan. "You are more familiar with it than I. What, then, do you suggest?"
