In itself the hunt was a success, and ten days after its inauguration, a well-laden safari took up its return march toward the Waziri plain. Lord and Lady Greystoke with Basuli and Mugambi rode together at the head of the column, laughing and talking together in that easy familiarity which common interests and mutual respect breed between honest and intelligent men of any races.

Jane Clayton’s horse shied suddenly at an object half hidden in the long grasses of an open space in the jungle. Tarzan’s keen eyes sought quickly for an explanation of the animal’s action.

“What have we here?” he cried, swinging from his saddle, and a moment later the four were grouped about a human skull and a little litter of whitened human bones.

Tarzan stooped and lifted a leathern pouch from the grisly relics of a man. The hard outlines of the contents brought an exclamation of surprise to his lips.

“The jewels of Opar!” he cried, holding the pouch aloft, “and,” pointing to the bones at his feet, “all that remains of Werper, the Belgian.”

Mugambi laughed. “Look within, Bwana,” he cried, “and you will see what are the jewels of Opar—you will see what the Belgian gave his life for,” and the black laughed aloud.

“Why do you laugh?” asked Tarzan.

“Because,” replied Mugambi, “I filled the Belgian’s pouch with river gravel before I escaped the camp of the Abyssinians whose prisoners we were. I left the Belgian only worthless stones, while I brought away with me the jewels he had stolen from you. That they were afterward stolen from me while I slept in the jungle is my shame and my disgrace; but at least the Belgian lost them—open his pouch and you will see.”

Tarzan untied the thong which held the mouth of the leathern bag closed, and permitted the contents to trickle slowly forth into his open palm. Mugambi’s eyes went wide at the sight, and the others uttered exclamations of surprise and incredulity, for from the rusty and weatherworn pouch ran a stream of brilliant, scintillating gems.

“The jewels of Opar!” cried Tarzan. “But how did Werper come by them again?”
