"But the Xujans—?" she asked, "may they not follow us here?"
"Yes," he said, "they probably will. But we need not be concerned with them until they come."
"I wish," said the girl, "that I possessed your philosophy but I am afraid it is beyond me."
"You were not born and reared in the jungle by wild beasts and among wild beasts, or you would possess, as I do, the fatalism of the jungle."
And so they moved to the side of the gorge beneath the shade of an overhanging rock and lay down in the hot sand to rest. Numa wandered restlessly to and fro and finally, after sprawling for a moment close beside the ape-man, rose and moved off up the gorge to be lost to view a moment later beyond the nearest turn.
For an hour the little party rested and then Tarzan suddenly rose and, motioning the others to silence, listened. For a minute he stood motionless, his keen ears acutely receptive to sounds so faint and distant that none of the other three could detect the slightest break in the utter and deathlike quiet of the gorge. Finally the ape-man relaxed and turned toward them. "What is it?" asked the girl.
"They are coming," he replied. "They are yet some distance away, though not far, for the sandaled feet of the men and the pads of the lions make little noise upon the soft sands."
"What shall we do—try to go on?" asked Smith-Oldwick. "I believe I could make a go of it now for a short way. I am much rested. How about you Miss Kircher?"
"Oh, yes," she said, "I am much stronger. Yes, surely I can go on."
Tarzan knew that neither of them quite spoke the truth, that people do not recover so quickly from utter exhaustion, but he saw no other way and there was always the hope that just beyond the next turn would be a way out of the gorge.
