A two days’ march brought them to a level plain beyond which lay mountains—a plain which Tarzan remembered and which aroused within him vague half memories and strange longings. Out upon the plain the horsemen rode, and at a safe distance behind them crept the ape-man, taking advantage of such cover as the ground afforded.
Beside a charred pile of timbers the Abyssinians halted, and Tarzan, sneaking close and concealing himself in nearby shrubbery, watched them in wonderment. He saw them digging up the earth, and he wondered if they had hidden meat there in the past and now had come for it. Then he recalled how he had buried his pretty pebbles, and the suggestion that had caused him to do it. They were digging for the things the blacks had buried here!
Presently he saw them uncover a dirty, yellow object, and he witnessed the joy of Werper and of Abdul Mourak as the grimy object was exposed to view. One by one they unearthed many similar pieces, all of the same uniform, dirty yellow, until a pile of them lay upon the ground, a pile which Abdul Mourak fondled and petted in an ecstasy of greed.
Something stirred in the ape-man’s mind as he looked long upon the golden ingots. Where had he seen such before? What were they? Why did these Tarmangani covet them so greatly? To whom did they belong?
He recalled the black men who had buried them. The things must be theirs. Werper was stealing them as he had stolen Tarzan’s pouch of pebbles. The ape-man’s eyes blazed in anger. He would like to find the black men and lead them against these thieves. He wondered where their village might be.
As all these things ran through the active mind, a party of men moved out of the forest at the edge of the plain and advanced toward the ruins of the burned bungalow.
Abdul Mourak, always watchful, was the first to see them, but already they were halfway across the open. He called to his men to mount and hold themselves in readiness, for in the heart of Africa who may know whether a strange host be friend or foe?
Werper, swinging into his saddle, fastened his eyes upon the newcomers, then, white and trembling he turned toward Abdul Mourak.
“It is Achmet Zek and his raiders,” he whispered. “They are come for the gold.”
It must have been at about the same instant that Achmet Zek discovered the pile of yellow ingots and realized the actuality of what he had already feared since first his eyes had alighted upon the party beside the ruins of the Englishman’s bungalow. Someone had forestalled him—another had come for the treasure ahead of him.
