and suffered the terrors of constant association with
him he thought a mad man, rather than give up the hope of obtaining
possession of the fortune which the contents of the little pouch
represented.

Achmet Zek should know nothing of these--these would be for Werper
alone, and so soon as he could encompass his design he would reach the
coast and take passage for America, where he could conceal himself
beneath the veil of a new identity and enjoy to some measure the fruits
of his theft. He had it all planned out, did Lieutenant Albert Werper,
living in anticipation the luxurious life of the idle rich. He even
found himself regretting that America was so provincial, and that
nowhere in the new world was a city that might compare with his beloved
Brussels.

It was upon the third day of their progress from Opar that the keen
ears of Tarzan caught the sound of men behind them. Werper heard
nothing above the humming of the jungle insects, and the chattering

For a time Tarzan stood in statuesque silence, listening, his sensitive

those other loyal Waziri.

When all had passed, Tarzan rose and emerged from concealment. He

"Why?" asked the Belgian.

"They are black," explained Tarzan. "It was a black who killed Kala.
They are the enemies of the Manganis."

Werper did not relish the idea of engaging in a battle with Basuli and
his fierce fighting men. And, again, he had welcomed the sight of them
returning toward the Greystoke bungalow, for he had begun to have
doubts as to his ability to retrace his steps to the Waziri country.
Tarzan, he knew, had not the remotest idea of whither they were going.
