those of the anthropoid. He saw him circle, stiff-legged about
the circling ape. He heard the same bestial barkings and growlings
issue from the human throat that were coming from the mouth of the
brute. Had his eyes been closed he could not have known but that
two giant apes were bridling for combat.

But there was no battle. It ended as the majority of such jungle
encounters end--one of the boasters loses his nerve, and becomes
suddenly interested in a blowing leaf, a beetle, or the lice upon
his hairy stomach.

In this instance it was the anthropoid that retired in stiff dignity
to inspect an unhappy caterpillar, which he presently devoured.
For a moment Tarzan seemed inclined to pursue the argument. He
swaggered truculently, stuck out his chest, roared and advanced
closer to the bull. It was with difficulty that Werper finally
persuaded him to leave well enough alone and continue his way from
the ancient city of the Sun Worshipers.

The two searched for nearly an hour before they found the narrow
exit through the inner wall. From there the well-worn trail led
them beyond the outer fortification to the desolate valley of Opar.

Tarzan had no idea, in so far as Werper could discover, as to where
he was or whence he came. He wandered aimlessly about, searching
for food, which he discovered beneath small rocks, or hiding in
the shade of the scant brush which dotted the ground.

The Belgian was horrified by the hideous menu of his companion.
Beetles, rodents and caterpillars were devoured with seeming relish.
