broken from a nearby branch, looked up at Tarzan with a pleasant
smile that revealed a row of strong white teeth, the canines of
which were no longer than Tarzan's own, spoke a few words which
Tarzan judged were a polite expression of thanks and then sought
a comfortable place in the tree for the night.

The earth was shadowed in the darkness which precedes the dawn when
Tarzan was awakened by a violent shaking of the tree in which he
had found shelter. As he opened his eyes he saw that his companion
was also astir, and glancing around quickly to apprehend the cause
of the disturbance, the ape-man was astounded at the sight which
met his eyes.

The dim shadow of a colossal form reared close beside the tree
and he saw that it was the scraping of the giant body against the
branches that had awakened him. That such a tremendous creature
could have approached so closely without disturbing him filled
Tarzan with both wonderment and chagrin. In the gloom the ape-man
at first conceived the intruder to be an elephant; yet, if so, one
of greater proportions than any he had ever before seen, but as the
dim outlines became less indistinct he saw on a line with his eyes
and twenty feet above the ground the dim silhouette of a grotesquely
serrated back that gave the impression of a creature whose each
and every spinal vertebra grew a thick, heavy horn. Only a portion
of the back was visible to the ape-man, the rest of the body being
lost in the dense shadows beneath the tree, from whence there now

From the odors that rose to the ape-man's sensitive nostrils he
presently realized that beneath him was some huge reptile feeding
upon the carcass of the lion that had been slain there earlier in
