but quickly doubled back toward the spot where he had left the white savage; for he was determined that if Ydeni would not lead him willingly to his village, he should do so unknowingly.
When Tarzan had returned to the spot where he killed the lion, the Kavuru was no longer there; and assuming that he had gone toward the north, his pursuer set off in that direction. After pursuing a northerly course for a short time, Tarzan realized that there were no indications that his quarry had come this way.
Quickly he started a great circle in order to pick up the scent spoor.
For an hour he ranged through forest and open glade before, at last, Usha, the wind, carried to his nostrils the scent spoor of Ydeni; and when at last he came upon the object of his search Tarzan was perplexed, for the Kavuru was moving due south.
Tarzan reasoned that Ydeni might be doing this to throw him off the trail, or perchance he had misinformed him as to the location of the Kavuru village; but he was sure now that if he clung tenaciously to the trail, Ydeni would eventually lead him to his goal.
Back over the long trail he had come since he had escaped from the village of Udalo , the chief, Tarzan dogged the footsteps of his quarry; yet never once was Ydeni aware that he was being followed, though oftentimes he was plainly visible to the ape-man.
Tarzan found it interesting to study this strange creature whose very existence was tinged with mystery. He noted the weapons and the ornaments of Ydeni and saw that they differed from any that he had ever seen before. He was particularly interested in the slender fibre rope that was wrapped many times around the Kavuru's waist; for of all the savages in the jungle, as far as Tarzan knew, he alone used a rope as a weapon. He wondered just how Ydeni would use it.
Late one afternoon, when Tarzan knew they must be approaching the village of the Bukena, he was surprised to see Ydeni take to the trees, through which he moved with considerable agility and speed, though in no respect to compare with those of the Lord of the Jungle.
He moved with the utmost wariness, stopping often to listen intently. Presently he uncoiled the rope from about his waist, and Tarzan saw there was a running noose in one end of it.
Now Tarzan heard voices ahead of them; they came faintly as from a great distance. It was evident that the Kavuru heard them, too, for he slightly changed his direction to bear more in that from which the voices came.
Tarzan was keenly interested. The attitude of the man in front of him was that of the keen hunter, stalking his prey. He felt that one mystery was about to be cleared up.
In a short time, the Kavuru came to the edge of a clearing and halted. Below him, working in the small fields, were a number of women. Ydeni looked them over; presently he espied a girl of about fifteen and made his way to another tree nearer her.
Tarzan followed, watching intently every move of the Kavuru. He heard him voice a strange call, so low that it must barely have reached the ears of the girl. For a moment she paid no attention to it; and then presently she turned and looked with dull, uncomprehending eyes toward the jungle. The sharpened stick with which she had been cultivating the maize dropped from her limp hand.
Ydeni continued to voice that weird, insistent call. The girl took a few steps in the direction of the jungle; then she paused; and Tarzan could almost sense the struggle that was going on within her breast to overcome the mysterious urge that was drawing her away from the other women; but Ydeni's voice was insistent and compelling, and at last she again moved listlessly toward him. She moved as one in a trance, with staring eyes fixed on Ydeni.
Now the Kavuru retreated slowly deeper into the forest, calling, always calling to the helpless girl that followed.
Tarzan watched; nor did he make any effort to interfere. To him, the life of the black girl was no more than the life of an antelope or that of any other beast of the jungle. To Tarzan, all were beasts, including himself, and none with any rights greater than another, except that which he might win by strength or cunning or ferocity.
Much more important than the life of the black girl was the possibility of fathoming the mystery that had always surrounded the disappearance of girls supposed to have been taken by the Kavuru.
Ydeni lured the girl deeper into the forest, halting at last upon a broad limb.
Slowly the girl approached. It was evident that she was not the master of her own will. The weird, monotonous droning chant of the Kavuru seemed to have numbed all her faculties.
At last, she came directly beneath the tree and the branch where Ydeni crouched. Then the man dropped his noose about her.
She made no outcry, no protest, as he tightened it and drew her slowly up toward him; nor ever once did the chant cease.
Removing the rope from about her, he threw her limp body across one of his broad shoulders and turning, started back in the direction from which he had come.
Tarzan had watched the abduction of the girl with keen interest, for it explained the seeming mystery of the disappearance of so many other young girls during past times.
He could readily understand the effect that these mysterious disappearances would have upon the superstitious minds of the natives; yet it was all very simple except the strange, hypnotic power of the Kavuru. That was not at all clear to him.
He wondered how the natives had come to connect these disappearances with the Kavuru, and the only reasonable explanation seemed to be that in times past some exceptionally tenacious relatives had prosecuted their search until they had come by accident upon the abductor and his prey and so learned the identity of the former without ascertaining the method he had used to achieve his ends.
Feeling no responsibility in the matter, Tarzan was not moved by any impulse to rescue the girl, his only concern now being to follow Ydeni back to the village of the Kavuru, where he was confident he would find Muviro's daughter, Buira, if she still lived.
Ydeni kept to the trees for hours, until he must have been reasonably certain that he had passed beyond the point where possible pursuers would be likely to search, since they had no trail to follow. Then he came to the ground; but he still carried the girl, who lay across his shoulder as one dead.
On and on he plodded, apparently tireless; and in the trees just behind him followed Tarzan of the Apes.
It was very late in the afternoon when the Kavuru halted. He carried the girl into a tree then, and tied her securely to a branch with the same rope that had snared her. Leaving her, he departed; and Tarzan followed him.
Ydeni was merely searching for food; and when he found some edible fruits and nuts, he returned with them to the girl.
The hypnosis which had held her in its spell for so long was now relinquishing its hold upon her, and as Ydeni approached her she looked at him with startled eyes and shrank away when he touched her.
Releasing her bonds, he carried her to the ground and offered her food.
By this time, full consciousness had returned; and it was evident that the girl was aware of her plight and the identity of her abductor, for an expression of utter horror distorted her features; and then she burst into tears.
'Shut up,' snapped Ydeni. 'I have not hurt you. If you give me no trouble, I shall not hurt you.'
'You are a Kavuru,' she gasped in horror-laden tones. 'Take me back to my father; you promised him that you would not harm any member of his family.'
Ydeni looked at the girl in surprise. 'I promised your father?' he demanded. 'I never saw your father; I have never spoken to one of your men.'
'You did. You promised him when he liberated you from the hut in which Udalo had you bound. Udalo would have killed you; my father, Gupingu, the witch-doctor, saved you. Because of that you made the promise.'
This recital made no impression upon Ydeni, but it did upon the grim and silent watcher in the trees above. So this was the daughter of Gupingu. Apparently Fate was a capricious wench with a strange sense of humor.
Knowledge of the identity of the girl gave a new complexion to the affair. Tarzan felt that by accepting his freedom at the hands of Gupingu he had given the witch-doctor passive assurance that his daughters would be safe from the Kavuru. It was a moral obligation that the Lord of the Jungle could not ignore; but if he took the girl from Ydeni and returned her to her people, he would be unable to follow the Kavuru to his village. However, with a shrug he accepted the responsibility that honor seemed to lay upon him.
Now he devoted himself to a consideration of ways and means. He could, of course, go down and take the girl by force, for it never occurred to him that any creature, least of all man, might be able to prevent him from
