sight grew dim; but not before he reached his goal and a
quick hand shot out to seize the knife that now lay within reach as the
two bodies tottered perilously upon the brink of the chasm.

With all his remaining strength the ape-man drove home the blade--once,
twice, thrice, and then all went black before him as he felt himself,
still in the clutches of the Tor-o-don, topple from the recess.

Fortunate it was for Tarzan that Pan-at-lee had not obeyed his
injunction to make good her escape while he engaged the Tor-o-don, for
it was to this fact that he owed his life. Close beside the struggling
forms during the brief moments of the terrific climax she had realized
every detail of the danger to Tarzan with which the emergency was
fraught and as she saw the two rolling over the outer edge of the niche
she seized the ape-man by an ankle at the same time throwing herself
prone upon the rocky floor. The muscles of the Tor-o-don relaxed in
death with the last thrust of Tarzan's knife and with its hold upon the
ape-man released it shot from sight into the gorge below.

It was with infinite difficulty that Pan-at-lee retained her hold upon
the ankle of her protector, but she did so and then, slowly, she sought
to drag the dead weight back to the safety of the niche. This, however,
was beyond her strength and she could but hold on tightly, hoping that
some plan would suggest itself before her powers of endurance failed.
She wondered if, after all, the creature was already dead, but that she
could not bring herself to believe--and if not dead how long it would
be before he regained consciousness. If he did not regain it soon he
never would regain it, that she knew, for she felt her fingers numbing
to the strain upon them and slipping, slowly, slowly, from their hold.
It was then that Tarzan regained consciousness. He could not know what
power upheld him, but he felt that whatever it was it was slowly
releasing its hold upon his ankle. Within easy reach of his hands were
two pegs and these he seized upon just as Pan-at-lee's fingers slipped
from their hold.

As it was he came near to being precipitated into the gorge--only his
great strength saved him. He was upright now and his feet found other
pegs. His first thought was of his foe. Where was he? Waiting above
there to finish him? Tarzan looked up just as the frightened face of
Pan-at-lee appeared over the threshold of the recess.

"You live?" she cried.

"Yes," replied T
