pillars, each capped by a huge, grotesque bird carved from the
solid rock of the monoliths.

As the ape-man and his companions stood gazing in varying degrees
of wonderment at this ancient city in the midst of savage Africa,
several of them became aware of movement within the structure at
which they were looking. Dim, shadowy shapes appeared to be moving
about in the semi-darkness of the interior. There was nothing
tangible that the eye could grasp--only an uncanny suggestion of
life where it seemed that there should be no life, for living things
seemed out of place in this weird, dead city of the long-dead past.

Tarzan recalled something that he had read in the library at Paris
of a lost race of white men that native legend described as living
in the heart of Africa. He wondered if he were not looking upon
the ruins of the civilization that this strange people had wrought
amid the savage surroundings of their strange and savage home. Could
it be possible that even now a remnant of that lost race inhabited
the ruined grandeur that had once been their progenitor? Again
he became conscious of a stealthy movement within the great temple
before him. "Come!" he said, to his Waziri. "Let us have a look
at what lies behind those ruined walls."

His men were loath to follow him, but when they saw that he
was bravely entering the frowning portal they trailed a few paces
behind in a huddled group that seemed the personification of nervous
terror. A single shriek such as they had heard the night before
would have been sufficient to have sent them all racing madly for
the narrow cleft that led through the great walls to the outer
world.
