“This is no time for useless noises of the mouth,” he said. “The Great Bwana has taught us that it is acts by which things are done, not words. Let us save our breath—we shall need it all to follow up the Arabs and slay them. If ‘Lady’ and our women live the greater the need of haste, and warriors cannot travel fast upon empty lungs.”

From the shelter of the reeds along the river, Werper and Tarzan watched the blacks. They saw them dig a trench with their knives and fingers. They saw them lay their yellow burdens in it and scoop the overturned earth back over the tops of the ingots.

Tarzan seemed little interested, after Werper had assured him that that which they buried was not good to eat; but Werper was intensely interested. He would have given much had he had his own followers with him, that he might take away the treasure as soon as the blacks left, for he was sure that they would leave this scene of desolation and death as soon as possible.

The treasure buried, the blacks removed themselves a short distance up wind from the fetid corpses, where they made camp, that they might rest before setting out in pursuit of the Arabs. It was already dusk. Werper and Tarzan sat devouring some pieces of meat they had brought from their last camp. The Belgian was occupied with his plans for the immediate future. He was positive that the Waziri would pursue Achmet Zek, for he knew enough of savage warfare, and of the characteristics of the Arabs and their degraded followers to guess that they had carried the Waziri women off into slavery. This alone would assure immediate pursuit by so warlike a people as the Waziri.

Werper felt that he should find the means and the opportunity to push on ahead, that he might warn Achmet Zek of the coming of Basuli, and also of the location of the buried treasure. What the Arab would now do with Lady Greystoke, in view of the mental affliction of her husband, Werper neither knew nor cared. It was enough that the golden treasure buried upon the site of the burned bungalow was infinitely more valuable than any ransom that would have occurred even to the avaricious mind of the Arab, and if Werper could persuade the raider to share even a portion of it with him he would be well satisfied.

But by far the most important consideration, to Werper, at least, was the incalculably valuable treasure in the little leathern pouch at Tarzan’s side. If he could but obtain possession of this! He must! He would!

His eyes wandered to the object of his greed. They measured Tarzan’s giant frame, and rested upon the rounded muscles of his arms. It was hopeless. What could he, Werper, hope to accomplish, other than his own death, by an attempt to wrest the gems from their savage owner?

Disconsolate, Werper threw himself upon his side. His head was pillowed on one arm, the other rested across his face in such a way that his eyes were hidden from the ape-man, though one of them was fastened upon him from beneath the shadow of the Belgian’s forearm. For a time he lay thus, glowering at Tarzan, and originating schemes for plundering him of his treasure—schemes that were discarded as futile as rapidly as they were born.

Tarzan presently let his own eyes rest upon Werper. The Belgian saw that he was being watched, and lay very still. After a few moments he simulated the regular breathing of deep slumber.

Tarzan had been thinking. He had seen the Waziri bury their belongings. Werper had told him that they were hiding them lest some one find them and take them away. This seemed to Tarzan a splendid plan for safeguarding valuables. Since Werper had evinced a desire to possess his glittering pebbles, Tarzan, with the suspicions of a savage, had guarded the baubles, of whose worth he was entirely ignorant, as zealously as though they spelled life or death to him.
