For a long time the ape-man sat watching his companion. At last, convinced that he slept, Tarzan withdrew his hunting knife and commenced to dig a hole in the ground before him. With the blade he loosened up the earth, and with his hands he scooped it out until he had excavated a little cavity a few inches in diameter, and five or six inches in depth. Into this he placed the pouch of jewels. Werper almost forgot to breathe after the fashion of a sleeper as he saw what the ape-man was doing—he scarce repressed an ejaculation of satisfaction.

Tarzan become suddenly rigid as his keen ears noted the cessation of the regular inspirations and expirations of his companion. His narrowed eyes bored straight down upon the Belgian. Werper felt that he was lost—he must risk all on his ability to carry on the deception. He sighed, threw both arms outward, and turned over on his back mumbling as though in the throes of a bad dream. A moment later he resumed the regular breathing.

Now he could not watch Tarzan, but he was sure that the man sat for a long time looking at him. Then, faintly, Werper heard the other’s hands scraping dirt, and later patting it down. He knew then that the jewels were buried.

It was an hour before Werper moved again, then he rolled over facing Tarzan and opened his eyes. The ape-man slept. By reaching out his hand Werper could touch the spot where the pouch was buried.

For a long time he lay watching and listening. He moved about, making more noise than necessary, yet Tarzan did not awaken. He drew the sacrificial knife from his belt, and plunged it into the ground. Tarzan did not move. Cautiously the Belgian pushed the blade downward through the loose earth above the pouch. He felt the point touch the soft, tough fabric of the leather. Then he pried down upon the handle. Slowly the little mound of loose earth rose and parted. An instant later a corner of the pouch came into view. Werper pulled it from its hiding place, and tucked it in his shirt. Then he refilled the hole and pressed the dirt carefully down as it had been before.

Greed had prompted him to an act, the discovery of which by his companion could lead only to the most frightful consequences for Werper. Already he could almost feel those strong, white fangs burying themselves in his neck. He shuddered. Far out across the plain a leopard screamed, and in the dense reeds behind him some great beast moved on padded feet.

Werper feared these prowlers of the night; but infinitely more he feared the just wrath of the human beast sleeping at his side. With utmost caution the Belgian arose. Tarzan did not move. Werper took a few steps toward the plain and the distant forest to the northwest, then he paused and fingered the hilt of the long knife in his belt. He turned and looked down upon the sleeper.

“Why not?” he mused. “Then I should be safe.”

He returned and bent above the ape-man. Clutched tightly in his hand was the sacrificial knife of the High Priestess of the Flaming God!
