e two who had formerly been locked in mortal combat stood facing
each other across the body of the common foe.

Tarzan waited, ready either for peace or war. Presently two shaggy
black hands were raised; the left was laid upon its own heart and the
right extended until the palm touched Tarzan's breast. It was the same
form of friendly salutation with which the pithecanthropus had sealed
his alliance with the ape-man and Tarzan, glad of every ally he could
win in this strange and savage world, quickly accepted the proffered
friendship.

At the conclusion of the brief ceremony Tarzan, glancing in the
direction of the hairless pithecanthropus, discovered that the latter
had recovered consciousness and was sitting erect watching them

lofty range towering above. Often were they menaced by the savage
denizens of this remote fastness, and occasionally Tarzan glimpsed
weird forms of gigantic proportions amidst the shadows of the nights.

On the third day they came upon a large natural cave in the face of a
low cliff at the foot of which tumbled one of the numerous mountain
brooks th
