r of development.

Man's survival does not hinge so greatly upon the perfection of his
senses. His power to reason has relieved them of many of their duties,
and so they have, to some extent, atrophied, as have the muscles which
move the ears and scalp, merely from disuse.

The muscles are there, about the ears and beneath the scalp, and so are
the nerves which transmit sensations to the brain, but they are
under-developed because they are not needed.

Not so with Tarzan of the Apes. From early infancy his survival had
depended upon acuteness of eyesight, hearing, smell, touch, and taste
far more than upon the more slowly developed organ of reason.

The least developed of all in Tarzan was the sense of taste, for he
could eat luscious fruits, or raw flesh, long buried with almost equal
appreciation; but in that he differed but slightly from more civilized
epicures.

Almost silently the ape-man sped on in the track of Terkoz and his
prey, but the sound of his approach reached the ears of the fleeing
beast and spurred it on to greater speed.

Three miles were covered before Tarzan overtook them, and then Terkoz,
seeing that further flight was futile, dropped to the ground in a small
open glade, that he might turn and fight for his prize or be free to
escape unhampered if he saw that the pursuer was more than a match for
him.

He still grasped Jane in one great arm as Tarzan bounded like a leopard
into the arena which nature had provided for this primeval-like battle.

When Terkoz saw that it was Tarzan who pursued him, he jumped to the
conclusion that this was Tarzan's woman, since they were of the same
kind--white and hairless--and so he rejoiced at this opportunity for
double revenge upon his hated enemy.

To Jane the strange apparition of this god-like man was as wine to sick
nerves.

From the description which Clayton and her father and Mr. Philander had
given her, she knew that it must be the same wonderful creature who had
saved them, and she saw in him only a protector and a friend.

But as Terkoz pushed her roughly aside to meet Tarzan's charge, and she
saw the great proportions of the ape and the mighty muscles and the
fierce fangs, her heart quailed. How could any vanquish such a mighty
antagonist?

Like two charging bulls they came together, and like two wolves sought
each other's throat. Against the long canines of the ape was pitted
the thin blade of the man's knife.

Jane--her lithe, you
