Presently he saw the muzzle of a rifle appear suddenly and mysteriously a few inches above the pouch, and before he could realize the cunning trick that the Arab had played upon him the sight of the weapon was adroitly hooked into the rawhide thong which formed the carrying strap of the pouch, and the latter was drawn quickly from his view into the dense foliage at the trail’s side.

Not for an instant had the raider exposed a square inch of his body, and Werper dared not fire his one remaining shot unless every chance of a successful hit was in his favor.

Chuckling to himself, Achmet Zek withdrew a few paces farther into the jungle, for he was as positive that Werper was waiting nearby for a chance to pot him as though his eyes had penetrated the jungle trees to the figure of the hiding Belgian, fingering his rifle behind the bole of the buttressed giant.

Werper did not dare advance—his cupidity would not permit him to depart, and so he stood there, his rifle ready in his hands, his eyes watching the trail before him with catlike intensity.

But there was another who had seen the pouch and recognized it, who did advance with Achmet Zek, hovering above him, as silent and as sure as death itself, and as the Arab, finding a little spot less overgrown with bushes than he had yet encountered, prepared to gloat his eyes upon the contents of the pouch, Tarzan paused directly above him, intent upon the same object.

Wetting his thin lips with his tongue, Achmet Zek loosened the tie strings which closed the mouth of the pouch, and cupping one claw-like hand poured forth a portion of the contents into his palm.

A single look he took at the stones lying in his hand. His eyes narrowed, a curse broke from his lips, and he hurled the small objects upon the ground, disdainfully. Quickly he emptied the balance of the contents until he had scanned each separate stone, and as he dumped them all upon the ground and stamped upon them his rage grew until the muscles of his face worked in demon-like fury, and his fingers clenched until his nails bit into the flesh.

Above, Tarzan watched in wonderment. He had been curious to discover what all the pow-wow about his pouch had meant. He wanted to see what the Arab would do after the other had gone away, leaving the pouch behind him, and, having satisfied his curiosity, he would then have pounced upon Achmet Zek and taken the pouch and his pretty pebbles away from him, for did they not belong to Tarzan?

He saw the Arab now throw aside the empty pouch, and grasping his long gun by the barrel, clublike, sneak stealthily through the jungle beside the trail along which Werper had gone.

As the man disappeared from his view, Tarzan dropped to the ground and commenced gathering up the spilled contents of the pouch, and the moment that he obtained his first near view of the scattered pebbles he understood the rage of the Arab, for instead of the glittering and scintillating gems which had first caught and held the attention of the ape-man, the pouch now contained but a collection of ordinary river pebbles.
