For a moment he stood thus, every sense alert. Then he called to Nkima in the tongue of the ape folk and as the little monkey scampered toward him, Tarzan of the Apes turned without a word of farewell and moved silently off into the jungle, his lithe carriage, his noiseless tread, his majestic mien suggesting to the mind of von Harben a personification of another mighty jungle animal, Numa the lion, king of beasts. _Chapter Two_ Erich von Harben stepped from his tent upon the slopes of the Wiramwazi Mountains to look upon a deserted camp. When he had first awakened, the unusual quiet of his surroundings had aroused within him a presentiment of ill, which was augmented when repeated calls for his body-servant, Gambula, elicited no response. For weeks, as the safari had been approaching the precincts of the feared Wiramwazi, his men had been deserting by twos and threes until the preceding evening when they had made this camp well upon the mountain slopes only a terrified remnant of the original safari had remained with him. Now even these, overcome during the night by the terrors of ignorance and superstition, had permitted fear to supplant loyalty and had fled from the impending and invisible terrors of this frowning range, leaving their master alone with the bloodthirsty spirits of the dead. A hasty survey of the camp site revealed that the blacks had stripped von Harben of everything. All of his supplies were gone and his gun carriers had decamped with his rifles and all of his ammunition, with the exception of a single Luger pistol and its belt of ammunition that had been in the tent with him. Erich von Harben had had sufficient experience with these natives to understand fairly well the mental processes based upon their deep-rooted superstition that had led them to this seemingly inhuman and disloyal act and so he did not place so much blame upon them as might another less familiar with them. While they had known their destination when they embarked upon the undertaking, their courage had been high in direct proportion to the great distance that they had been from the Wiramwazi, but in proportion as the distance lessened with each day's march their courage had lessened until now upon the very threshold of horrors beyond the ken of human minds the last vestige of self-control had deserted them and they had fled precipitately. That they had taken his provisions, his rifles and his ammunition might have seemed the depth of baseness had von Harben not realized the sincerity of their belief that there could be no possible hope for him and that his immediate death was a foregone conclusion.
