The Professor seemed weak and unnerved, for he stumbled among the loose stones that littered the way and would have fallen more than once had not his guard steadied him. His head was bare and his clothing torn in many places. Doubtless the fellow had struggled desperately before he had finally been secured.

They led Van Dorn to the end of the ravine opposite us and placed him with his back against the rock. The Bega and the Bisharin from Laketa, all animated and talking eagerly in their native tongue, formed a group fifty yards away. Prominent amongst them we could see the dwarfed, withered form of the aged chief, and the stalwart, towering figure of Ketti.

Gege-Merak gave an order and a man stepped forward and leveled his rifle at the Professor. Before he could fire, Van Dorn shrieked in terror and dropped to the ground. They raised him again, cuffing and shaking him until once more he stood upright. Yet he trembled visibly. Again the Bega warrior raised his rifle, but, answering the victim’s pitiful screams, Ketti now sprang before the man and wrenched away his weapon, protesting so loudly that his voice reached even to our high nest on the cliff against the deed the chief had ordered.

Gege-Merak fairly danced with rage at this defiance. He gave a command which at first his men seemed reluctant to execute, but finally two of them approached Ketti, seized him and drew him away, binding his arms to his sides. Iva was frantic at this act, and we had to warn her several times to be quiet or we should surely be discovered by those below.

It was while I was busy soothing Iva that I heard a shot and a cry of agony, and turned in time to see Van Dorn fall flat upon his face. Poor fellow, the treasure had cost him his life. However treacherous he had been in his dealings with Lovelace, with Abdul Hashim and with us, his final alliance with old Gege-Merak had brought him into contact with a nature as unscrupulous as his own, and the barbaric chief had evened up all scores by robbing the man of his ill-gotten wealth and his life at once.

But it seemed that Gege-Merak’s vengeance was not yet complete, and we could see from the tense and strained attitudes of the warriors that Van Dorn’s death was but an incident in the drama. If, indeed, the chief had cause to hate Ketti, that young man’s rash interference with his commands had given Gege-Merak the chance, perhaps long desired, to punish him. It may be he lived in fear of the handsome fellow who was destined to succeed him at his death, for Ketti’s popularity with the tribe was indisputable. Anyway, his orders, now given in a firm, loud voice, seemed instantly to seal the fate of Iva’s lover.

Bound and helpless as he was, the young man was led to the spot where Van Dorn had stood and set with his back against the wall of rock. But there was no craven spirit in the victim this time. Proudly the warrior stood facing his chief, his pose erect, his dark eyes calmly regarding his destroyer and a slight smile of scorn curling his lips.

Gege-Merak shouted his commands, but not a tribesman moved to obey. Softly Iva reached out her hand and grasped my repeating rifle, and I let her take it. She knelt before me, her brown face rigid, her eyes dark with horror, and rested the barrel on the ledge of rock before her. I saw Uncle Naboth and Ned glance at each other significantly; but they made no move to interfere.

Again and again the chief shouted his orders, waving his arms imperiously and stamping his foot in rage; but the Bega stood stolid and unyielding, and their Bisharin allies shrank back and huddled in a frightened group in the rear.

Gege-Merak himself snatched a rifle from a warrior’s hand and swinging around leveled it full at Ketti. At the same instant Iva’s rifle cracked beside me and I saw the aged chief totter, drop his weapon and sink slowly to the earth. A shout went up from the assembled group below, and with one impulse they turned their eyes toward us.
