Nor had they long to wait. A dim, bulky form dropped lightly from the branches of a tree into the camp. At sight of it one of the sentries recovered command of his muscles and his voice. Screaming loudly to awaken the sleeping camp, he leaped toward the flickering watch fire and threw a mass of brush upon it.
The white officer and the black soldiers sprang from their blankets. The flames leaped high upon the rejuvenated fire, lighting the entire camp, and the awakened men shrank back in superstitious terror from the sight that met their frightened and astonished vision.
A dozen huge and hairy forms loomed large beneath the trees at the far side of the enclosure. The white giant, one hand freed, had struggled to his knees and was calling to the frightful, nocturnal visitors in a hideous medley of bestial gutturals, barkings and growlings.
Werper had managed to sit up. He, too, saw the savage faces of the approaching anthropoids and scarcely knew whether to be relieved or terror-stricken.
Growling, the great apes leaped forward toward Tarzan and Werper. Chulk led them. The Belgian officer called to his men to fire upon the intruders; but the Negroes held back, filled as they were with superstitious terror of the hairy treemen, and with the conviction that the white giant who could thus summon the beasts of the jungle to his aid was more than human.
Drawing his own weapon, the officer fired, and Tarzan fearing the effect of the noise upon his really timid friends called to them to hasten and fulfill his commands.
A couple of the apes turned and fled at the sound of the firearm; but Chulk and a half dozen others waddled rapidly forward, and, following the ape-man’s directions, seized both him and Werper and bore them off toward the jungle.
By dint of threats, reproaches and profanity the Belgian officer succeeded in persuading his trembling command to fire a volley after the retreating apes. A ragged, straggling volley it was, but at least one of its bullets found a mark, for as the jungle closed about the hairy rescuers, Chulk, who bore Werper across one broad shoulder, staggered and fell.
In an instant he was up again; but the Belgian guessed from his unsteady gait that he was hard hit. He lagged far behind the others, and it was several minutes after they had halted at Tarzan’s command before he came slowly up to them, reeling from side to side, and at last falling again beneath the weight of his burden and the shock of his wound.
As Chulk went down he dropped Werper, so that the latter fell face downward with the body of the ape lying half across him. In this position the Belgian felt something resting against his hands, which were still bound at his back—something that was not a part of the hairy body of the ape.
