At last Werper succeeded in leading his companion toward the distant hills which mark the northwestern boundary of the valley, and together the two set out in the direction of the Greystoke bungalow.

What purpose prompted the Belgian in leading the victim of his treachery and greed back toward his former home it is difficult to guess, unless it was that without Tarzan there could be no ransom for Tarzan’s wife.

That night they camped in the valley beyond the hills, and as they sat before a little fire where cooked a wild pig that had fallen to one of Tarzan’s arrows, the latter sat lost in speculation. He seemed continually to be trying to grasp some mental image which as constantly eluded him.

At last he opened the leathern pouch which hung at his side. From it he poured into the palm of his hand a quantity of glittering gems. The firelight playing upon them conjured a multitude of scintillating rays, and as the wide eyes of the Belgian looked on in rapt fascination, the man’s expression at last acknowledged a tangible purpose in courting the society of the ape-man.

CHAPTER IX.
The Theft of the Jewels

For two days Werper sought for the party that had accompanied him from the camp to the barrier cliffs; but not until late in the afternoon of the second day did he find clew to its whereabouts, and then in such gruesome form that he was totally unnerved by the sight.

In an open glade he came upon the bodies of three of the blacks, terribly mutilated, nor did it require considerable deductive power to explain their murder. Of the little party only these three had not been slaves. The others, evidently tempted to hope for freedom from their cruel Arab master, had taken advantage of their separation from the main camp, to slay the three representatives of the hated power which held them in slavery, and vanish into the jungle.

Cold sweat exuded from Werper’s forehead as he contemplated the fate which chance had permitted him to escape, for had he been present when the conspiracy bore fruit, he, too, must have been of the garnered.

Tarzan showed not the slightest surprise or interest in the discovery. Inherent in him was a calloused familiarity with violent death. The refinements of his recent civilization expunged by the force of the sad calamity which had befallen him, left only the primitive sensibilities which his childhood’s training had imprinted indelibly upon the fabric of his mind.

The training of Kala, the examples and precepts of Kerchak, of Tublat, and of Terkoz now formed the basis of his every thought and action. He retained a mechanical knowledge of French and English speech. Werper had spoken to him in French, and Tarzan had replied in the same tongue without conscious realization that he had departed from the anthropoidal speech in which he had addressed La. Had Werper used English, the result would have been the same.
