That night Tarzan lay up under an overhanging shelf of rock. The next morning he resumed his journey, stopping only long enough to make a kill and satisfy his hunger. The other beasts of the wild eat and lie up; but Tarzan never let his belly interfere with his plans. In this lay one of the great-est differences between the ape-man and his fellows of the jungles and forests. The firing ahead rose and fell during the day. He had noticed that it was highest at dawn and immediately after dusk and that during the night it almost ceased. In the middle of the afternoon of the second day he came upon troops moving up toward the front. They ap-peared to be raiding parties, for they drove goats and cows along with them and there were native porters laden with grain and other foodstuffs. He saw that these natives were all secured by neck chains and he also saw that the troops were composed of native soldiers in German uniforms. The officers were white men. No one saw Tarzan, yet he was here and there about and among them for two hours. He inspected the insignia upon their uniforms and saw that they were not the same as that which he had taken from one of the dead soldiers at the bungalow and then he passed on ahead of them, unseen in the dense bush. He had come upon Germans and had not killed them; but it was because the killing of Germans at large was not yet the prime motive of his existence -- now it was to discover the individual who slew his mate.
After he had accounted for him he would take up the little matter of slaying ALL Germans who crossed his path, and he meant that many should cross it, for he would hunt them precisely as professional hunters hunt the man-eaters.
As he neared the front lines the troops became more numer-ous. There were motor trucks and ox teams and all the impedimenta of a small army and always there were wounded men walking or being carried toward the rear. He had crossed the railroad some distance back and judged that the wounded were being taken to it for transportation to a base hospital and possibly as far away as Tanga on the coast.
It was dusk when he reached a large camp hidden in the foothills of the Pare Mountains. As he was approaching from the rear he found it but lightly guarded and what sentinels there were, were not upon the alert, and so it was an easy thing for him to enter after darkness had fallen and prowl about listening at the backs of tents, searching for some clew to the slayer of his mate.
As he paused at the side of a tent before which sat a num-ber of native soldiers he caught a few words spoken in native dialect that riveted his attention instantly: "The Waziri fought like devils; but we are greater fighters and we killed them all.
When we were through the captain came and killed the woman. He stayed outside and yelled in a very loud voice until all the men were killed. Underlieutenant von Goss is braver -- he came in and stood beside the door shouting at us, also in a very loud voice, and bade us nail one of the Waziri who was wounded to the wall, and then he laughed loudly because the man suffered. We all laughed. It was very funny."Like a beast of prey, grim and terrible, Tarzan crouched in the shadows beside the tent. What thoughts passed through that savage mind? Who may say? No outward sign of passion was revealed by the expression of the handsome face;the cold, gray eyes denoted only intense watchfulness. Pres-ently the soldier Tarzan had heard first rose and with a parting word turned away. He passed within ten feet of the ape-man and continued on toward the rear of the camp. Tarzan fol-lowed and in the shadows of a clump of bushes overtook his quarry. There was no sound as the man beast sprang upon the back of his prey and bore it to the ground for steel fingers closed simultaneously upon the soldier's throat, effectually stifling any outcry. By the neck Tarzan dragged his victim well into the concealment of the bushes.
"Make no sound," he cautioned in the man's own tribal dialect as he released his hold upon the other's throat.
The fellow gasped for breath, rolling frightened eyes up-ward to see what manner of creature it might be in whose power he was. In the darkness he saw only a naked brown body bending above him; but he still remembered the terrific strength of the mighty muscles that had closed upon his wind and dragged him into the bushes as though he had been but a little child. If any thought of resistance had crossed his mind he must have discarded it at once, as he made no move to escape.
"What is the name of the officer who killed the woman at the bungalow where you fought with the Waziri?" asked Tarzan.
"Hauptmann Schneider," replied the black when he could again command his voice.
"Where is he?" demanded the ape-man.
"He is here. It may be that he is at headquarters. Many of the officers go there in the evening to receive orders.""Lead me there," commanded Tarzan, "and if I am dis-covered I will kill you immediately. Get up!"The black rose and led the way by a roundabout route back through the camp. Several times they were forced to hide while soldiers passed; but at last they reached a great pile of baled hay from about the corner of which the black pointed out a two-story building in the distance.
"Headquarters," he said. "You can go no farther unseen.
There are many soldiers about."
Tarzan realized that he could not proceed farther in com-pany with the black. He turned and looked at the fellow for a moment as though pondering what disposition to make of him.
"You helped to crucify Wasimbu, the Waziri," he accused in a low yet none the less terrible tone.
The black trembled, his knees giving beneath him. "He ordered us to do it," he plead.
"Who ordered it done?" demanded Tarzan.
