it was Tarzan of the Apes that put a savage foot upon the body of
his savage kill, and, raising his face to the full moon, lifted
his mighty voice in the weird and terrible challenge of his kind--a
bull ape had made his kill. And the wild things in the wild
mountains stopped in their hunting, and trembled at this new and
awful voice, while down in the desert the children of the wilderness
came out of their goatskin tents and looked toward the mountains,
wondering what new and savage scourge had come to devastate their
flocks.

A half mile from the valley in which Tarzan stood, a score of
white-robed figures, bearing long, wicked-looking guns, halted at
the sound, and looked at one another with questioning eyes. But
presently, as it was not repeated, they took up their silent,
stealthy way toward the valley.

Tarzan was now confident that Gernois had no intention of returning
for him, but he could not fathom the object that had prompted the
officer to desert him, yet leave him free to return to camp. His
horse gone, he decided that it would be foolish to remain longer
in the mountains, so he set out toward the desert.

He had scarcely entered the confines of the canon when the first of
the white-robed figures emerged into the valley upon the opposite
side. For a moment they scanned the little depression from behind
sheltering bowlders, but when they had satisfied themselves that
it was empty they advanced across it. Beneath the tree at one side
they came upon the body of EL ADREA. With muttered exclamations
they crowded about it. Then, a moment later, they hurried down
the canon which Tarzan was threading a brief distance in advance
