The enforced delays caused no irritation or nervousness such as they would have in an ordinary man, for the patience of the hunting beast is infinite. Tarzan knew that eventually he would overhaul his quarry, and that while they were on the move the girl was comparatively safe.
Dawn broke as he crossed the river. Far ahead he heard the roaring of a hunting lion, and presently with it were mingled the snarls and screams of another beast—a gorilla. And the ape-man knew that Numa had attacked one of the great apes. He guessed that it was the gorilla king. But what of the girl? He heard no human voice mingling its screams with that of the anthropoid. He broke into a run.
Presently, from a little rise of rolling ground, he saw Numa crouching upon his kill. It was light enough now for him to see that the lion was feeding upon the body of a gorilla. The girl was nowhere in sight.
Tarzan made a detour to avoid the feeding carnivore. He had no intention of risking an encounter with the king of beasts—an encounter that would certainly delay him and possibly end in death.
He passed at a considerable distance upwind from the lion; and when the beast caught his scent it turned its head in his direction and growled, but it did not rise from its kill.
Beyond the lion, near the edge of the wood, Tarzan picked up the trail of the girl again. He followed it across the second river. It turned south here, upwind; and now he was below her and could follow her scent spoor easily. At a trot he pressed on.
Now other scent spoor impinged upon his nostrils, mingling with those of the girl. They were strange scents—a mixture of mangani and tarmangani, of great ape and white man, of male and of female.
Tarzan increased his gait. That strange instinct that he shared with the other beasts of the forest warned him that danger lay ahead—danger for the girl and perhaps for himself. He moved swiftly and silently through the fringe of forest that bordered the river.
The strange scents became stronger in his nostrils. A babel of angry voices arose in the distance ahead. He was nearing them. He took to the trees now, to his native element; and he felt at once the sense of security and power that the trees always imparted to him. Here, as nowhere else quite in the same measure, was he indeed lord of the jungle.
Now he heard the angry, raging voice of a female. It was almost human, yet the beast notes predominated; and he could recognize words spoken in the language of the great apes. Tarzan was mystified.
