The Belgian lost his temper. “I have no disposition to argue with a naked savage,” he cried. “Unless you wish to be hurt you will not interfere with me. Take the prisoner, Sergeant!”

Werper raised his lips close to Tarzan’s ear. “Keep me from them, and I can show you the very spot where I saw your wife last night,” he whispered. “She cannot be far from here at this very minute.”

The soldiers, following the signal from their sergeant, closed in to seize Werper. Tarzan grabbed the Belgian about the waist, and bearing him beneath his arm as he might have borne a sack of flour, leaped forward in an attempt to break through the cordon. His right fist caught the nearest soldier upon the jaw and sent him hurtling backward upon his fellows. Clubbed rifles were torn from the hands of those who barred his way, and right and left the black soldiers stumbled aside in the face of the ape-man’s savage break for liberty.

So completely did the blacks surround the two that they dared not fire for fear of hitting one of their own number, and Tarzan was already through them and upon the point of dodging into the concealing mazes of the jungle when one who had sneaked upon him from behind struck him a heavy blow upon the head with a rifle.

In an instant the ape-man was down and a dozen black soldiers were upon his back. When he regained consciousness he found himself securely bound, as was Werper also. The Belgian officer, success having crowned his efforts, was in good humor, and inclined to chaff his prisoners about the ease with which they had been captured; but from Tarzan of the Apes he elicited no response. Werper, however, was voluble in his protests. He explained that Tarzan was an English lord; but the officer only laughed at the assertion, and advised his prisoner to save his breath for his defense in court.

As soon as Tarzan regained his senses and it was found that he was not seriously injured, the prisoners were hastened into line and the return march toward the Congo Free State boundary commenced.

Toward evening the column halted beside a stream, made camp and prepared the evening meal. From the thick foliage of the nearby jungle a pair of fierce eyes watched the activities of the uniformed blacks with silent intensity and curiosity. From beneath beetling brows the creature saw the boma constructed, the fires built, and the supper prepared.

Tarzan and Werper had been lying bound behind a small pile of knapsacks from the time that the company had halted; but with the preparation of the meal completed, their guard ordered them to rise and come forward to one of the fires where their hands would be unfettered that they might eat.

As the giant ape-man rose, a startled expression of recognition entered the eyes of the watcher in the jungle, and a low guttural broke from the savage lips. Instantly Tarzan was alert, but the answering growl died upon his lips, suppressed by the fear that it might arouse the suspicions of the soldiers.

Suddenly an inspiration came to him. He turned toward Werper.
