eenacted with another
howling victim.

Tarzan rose and stretched lazily. The entertainment was beginning to
bore him. He yawned and turned upon his way toward the clearing where
the tribe would be sleeping in the encircling trees.

Yet even when he had found his familiar crotch and curled himself for
slumber, he felt no desire to sleep. For a long time he lay awake
thinking and dreaming. He looked up into the heavens and watched the
moon and the stars. He wondered what they were and what power kept
them from falling. His was an inquisitive mind. Always he had been
full of questions concerning all that passed around him; but there
never had been one to answer his questions. In childhood he had wanted
to KNOW, and, denied almost all knowledge, he still, in manhood, was
filled with the great, unsatisfied curiosity of a child.

He was never quite content merely to perceive that things happened--he
desired to know WHY they happened. He wanted to know what made things
go. The secret of life interested him immensely. The miracle of death
he could not quite fathom. Upon innumerable occasions he had
investigated the internal mechanism of his kills, and once or twice he
had opened the chest cavity of victims in time to see the heart still
pumping.

He had learned from experience that a knife thrust through this organ
brought immediate death nine times out of ten, while he might stab an
antagonist innumerable times in other places without even disabling
him. And so he had come to think of the heart, or, as he called it,
"the red thing that breathes," as the seat and origin of life.

The brain and its functionings he did not comprehend at all. That his
sense perceptions were transmitted to his brain and there translated,
classified, and labeled was something quite beyond him. He thought
that his fingers knew when they touched something, that his eyes knew
when they saw, his ears when they heard, his nose when it scented.

He considered his throat, epidermis, and the hairs of his head as the
three principal seats of emotion. When Kala had been slain a peculiar
choking sensation had possessed his throat; contact with Histah, the
snake, imparted an unpleasant sensation to the skin of his whole body;
while the approach of an enemy made the hairs on his scalp stand erect.

Imagine, if you can, a child filled with the wonders of nature,
bursting with queries and surrounded only by beasts of the jungle to
whom his
