He saw the zebra's tail dipped into a caldron of water above which the witch-doctor had made magical passes the while he danced and leaped about it, and he saw the breasts and foreheads of each of the three novitiates sprinkled with the charmed liquid. Could the ape-man have known the purpose of this act, that it was intended to render the recipient invulnerable to the attacks of his enemies and fearless in the face of any danger, he would doubtless have leaped into the village street and appropriated the zebra's tail and a portion of the contents of the caldron.

But he did not know, and so he only wondered, not alone at what he saw but at the strange sensations which played up and down his naked spine, sensations induced, doubtless, by the same hypnotic influence which held the black spectators in tense awe upon the verge of a hysteric upheaval.

The longer Tarzan watched, the more convinced he became that his eyes were upon God, and with the conviction came determination to have word with the deity. With Tarzan of the Apes, to think was to act.

The people of Mbonga were keyed to the highest pitch of hysterical excitement. They needed little to release the accumulated pressure of static nerve force which the terrorizing mummery of the witch-doctor had induced.

A lion roared, suddenly and loud, close without the palisade.

The blacks started nervously, dropping into utter silence as they listened for a repetition of that all-too-familiar and always terrorizing voice. Even the witch-doctor paused in the midst of an intricate step, remaining momentarily rigid and statuesque as he plumbed his cunning mind for a suggestion as how best he might take advantage of the condition of his audience and the timely interruption.

Already the evening had been vastly profitable to him.

There would be three goats for the initiation of the three youths into full-fledged warriorship, and besides these he had received several gifts of grain and beads, together with a piece of copper wire from admiring and terrified members of his audience.

Numa's roar still reverberated along taut nerves when a woman's laugh, shrill and piercing, shattered the silence of the village. It was this moment that Tarzan chose to drop lightly from his tree into the village street.

Fearless among his blood enemies he stood, taller by a full head than many of Mbonga's warriors, straight as their straightest arrow, muscled like Numa, the lion.

For a moment Tarzan stood looking straight at the witch-doctor. Every eye was upon him, yet no one had moved-- a paralysis of terror held them, to be broken a moment later as the ape-man, with a toss of head, stepped straight toward the hideous figure beneath the buffalo head.

Then the nerves of the blacks could stand no more.

For months the terror of the strange, white, jungle god had been upon them. Their arrows had been stolen from the very center of the village; their warriors had been silently slain upon the jungle trails and their dead bodies dropped mysteriously and by night into the village street as from the heavens above.

One or two there were who had glimpsed the strange figure of the new demon and it was from their oft-repeated descriptions that the entire village now recognized Tarzan as the author of many of their ills. Upon another occasion and by daylight, the warriors would doubtless have leaped to attack him, but at night, and this night of all others, when they were wrought to such a pitch of nervous dread by the uncanny artistry of their witch-doctor, they were helpless with terror. As one man they turned and fled, scattering for their huts, as Tarzan advanced.

For a moment one and one only held his ground. It was the witch-doctor. More than half self-hypnotized into a belief in his own charlatanry he faced this new demon who threatened to undermine his ancient and lucrative profession.

"Are you God?" asked Tarzan.

The witch-doctor, having no idea of the meaning of the other's words, danced a few strange steps, leaped high in the air, turning completely around and alighting in a stooping posture with feet far outspread and head thrust out toward the ape-man. Thus he remained for an instant before he uttered a loud "Boo!" which was evidently intended to frighten Tarzan away; but in reality had no such effect.

Tarzan did not pause. He had set out to approach and examine God and nothing upon earth might now stay his feet.

Seeing that his antics had no potency with the visitor, the witch-doctor tried some new medicine. Spitting upon the zebra's tail, which he still clutched in one hand, he made circles above it with the arrows in the other hand, meanwhile backing cautiously away from Tarzan and speaking confidentially to the bushy end of the tail.

This medicine must be short medicine, however, for the creature, god or demon, was steadily closing up the distance which had separated them. The circles therefore were few and rapid, and when they were completed, the witch-doctor struck an attitude which was intended to be awe inspiring and waving the zebra's tail before him, drew an imaginary line between himself and Tarzan.

"Beyond this line you cannot pass, for my medicine is strong medicine," he cried. "Stop, or you will fall dead as your foot touches this spot. My mother was a voodoo, my father was a snake; I live upon lions' hearts and the entrails of the panther; I eat young babies for breakfast and the demons of the jungle are my slaves.

I am the most powerful witch-doctor in the world;I fear nothing, for I cannot die. I--" But he got no further;instead he turned and fled as Tarzan of the Apes crossed the magical dead line and still lived.

As the witch-doctor ran, Tarzan almost lost his temper.

This was no way for God to act, at least not in accordance with the conception Tarzan had come to have of God.
