se of these differences Tarzan loved to investigate the jungle by
night. Not only was the life another life; but it was richer in
numbers and in romance; it was richer in dangers, too, and to Tarzan of
the Apes danger was the spice of life. And the noises of the jungle
night--the roar of the lion, the scream of the leopard, the hideous
laughter of Dango, the hyena, were music to the ears of the ape-man.

The soft padding of unseen feet, the rustling of leaves and grasses to
the passage of fierce beasts, the sheen of opalesque eyes flaming
through the dark, the million sounds which proclaimed the teeming life
that one might hear and scent, though seldom see, constituted the
appeal of the nocturnal jungle to Tarzan.

Tonight he had swung a wide circle--toward the east first and then
toward the south, and now he was rounding back again into the north.
His eyes, his ears and his keen nostrils were ever on the alert.
Mingled with the sounds he knew, there were strange sounds--weird
sounds which he never heard until after Kudu had sought his lair below
the far edge of the big water-sounds which belonged to Goro, the
moon--and to the mysterious period of Goro's supremacy. These sounds
often caused Tarzan profound speculation. They baffled him because he
thought that he knew his jungle so well that there could be nothing
within it unfamiliar to him. Sometimes he thought that as colors and
forms appeared to differ by night from their familiar daylight aspects,
so sounds altered with the passage of Kudu and the coming of Goro, and
these thoughts roused within his brain a vague conjecture that perhaps
Goro and Kudu influenced these changes. And what more natural that
eventually he came to attribute to the sun and the moon personalities
as real as his own? The sun was a living creature and ruled the day.
The moon, endowed with brains and miraculous powers, ruled the night.

Thus functioned the untrained man-mind groping through the dark night
of ignorance for an explanation of the things he could not touch or
smell or hear and of the great, unknown powers of nature which he could
not see.

As Tarzan swung north again upon his wide circle the scent of the
Gomangani came to his nostrils, mixed with the acrid odor of wood
smoke. The ape-man moved quickly in the direction from which the scent
was borne down to him upon the gentle night wind. Presently the ruddy
sheen of a great fire filtered through the foliage to him ahead,
