They saw the new-comer place a foot upon the neck of the quiet figure at his feet and, throwing back his head, give vent to the wild, uncanny challenge of the bull-ape that has made a kill. Then they knew that their king was dead.

Across the jungle rolled the horrid notes of the victory cry. The little monkeys in the tree-tops ceased their chattering. The harsh-voiced, brilliant-plumed birds were still. From afar came the answering wail of a leopard and the deep roar of a lion.

It was the old Tarzan who turned questioning eyes upon the little knot of apes before him. It was the old Tarzan who shook his head as though to toss back a heavy mane that had fallen before his face—an old habit dating from the days that his great shock of thick, black hair had fallen about his shoulders, and often tumbled before his eyes when it had meant life or death to him to have his vision unobstructed.

The ape-man knew that he might expect an immediate attack on the part of that particular surviving bull-ape who felt himself best fitted to contend for the kingship of the tribe. Among his own apes he knew that it was not unusual for an entire stranger to enter a community and, after having dispatched the king, assume the leadership of the tribe himself, together with the fallen monarch’s mates.

On the other hand, if he made no attempt to follow them, they might move slowly away from him, later to fight among themselves for the supremacy. That he could be king of them, if he so chose, he was confident; but he was not sure he cared to assume the sometimes irksome duties of that position, for he could see no particular advantage to be gained thereby.

One of the younger apes, a huge, splendidly muscled brute, was edging threateningly closer to the ape-man. Through his bared fighting fangs there issued a low, sullen growl.

Tarzan watched his every move, standing rigid as a statue. To have fallen back a step would have been to precipitate an immediate charge; to have rushed forward to meet the other might have had the same result, or it might have put the bellicose one to flight—it all depended upon the young bull’s stock of courage.

To stand perfectly still, waiting, was the middle course. In this event the bull would, according to custom, approach quite close to the object of his attention, growling hideously and baring slavering fangs. Slowly he would circle about the other, as though with a chip upon his shoulder; and this he did, even as Tarzan had foreseen.

It might be a bluff royal, or, on the other hand, so unstable is the mind of an ape, a passing impulse might hurl the hairy mass, tearing and rending, upon the man without an instant’s warning.

As the brute circled him Tarzan turned slowly, keeping his eyes ever upon the eyes of his antagonist. He had appraised the young bull as one who had never quite felt equal to the task of overthrowing his former king, but who one day would have done so. Tarzan saw that the beast was of wondrous proportions, standing over seven feet upon his short, bowed legs.
