In a few minutes more Tarzan swung into the trees above Mbonga’s village. Ah, he was not quite too late! Or, was he? He could not tell. The figure at the stake was very still, yet the black warriors were but pricking it.

Tarzan knew their customs. The death blow had not been struck. He could tell almost to a minute how far the dance had gone.

In another instant Mbonga’s knife would sever one of the victim’s ears—that would mark the beginning of the end, for very shortly after only a writhing mass of mutilated flesh would remain.

There would still be life in it, but death then would be the only charity it craved.

The stake stood forty feet from the nearest tree. Tarzan coiled his rope. Then there rose suddenly above the fiendish cries of the dancing demons the awful challenge of the ape-man.

The dancers halted as though turned to stone.

The rope sped with singing whir high above the heads of the blacks. It was quite invisible in the flaring lights of the camp fires.

D’Arnot opened his eyes. A huge black, standing directly before him, lunged backward as though felled by an invisible hand.

Struggling and shrieking, his body, rolling from side to side, moved quickly toward the shadows beneath the trees.

The blacks, their eyes protruding in horror, watched spellbound.
