Inch by inch at first Numa advanced. He was growling now and presently he commenced to roar. Suddenly he leaped forward and Tarzan knew that he had caught the scent of meat ahead. Dragging the machine gun beside him the ape-man followed quickly after the lion whose roars he could plainly hear ahead mingled with the unmistakable screams of frightened men. Once again a grim smile touched the lips of this man-beast.

"They murdered my Waziri," he muttered; "they crucified Wasimbu, son of Muviro."

When Tarzan reached the trench and emerged into it there was no one in sight in that particular bay, nor in the next, nor the next as he hurried forward in the direction of the German center; but in the fourth bay he saw a dozen men jammed in the angle of the traverse at the end while leaping upon them and rending with talons and fangs was Numa, a terrific incarnation of ferocity and ravenous hunger.

Whatever held the men at last gave way as they fought madly with one another in their efforts to escape this dread creature that from their infancy had filled them with terror, and again they were retreating. Some clambered over the parados and some even over the parapet preferring the dangers of No Man's Land to this other soul-searing menace.

As the British advanced slowly toward the German trenches, they first met terrified blacks who ran into their arms only too willing to surrender. That pandemonium had broken loose in the Hun trench was apparent to the Rhodesians not only from the appearance of the deserters, but from the sounds of screaming, cursing men which came clearly to their ears; but there was one that baffled them for it resembled nothing more closely than the infuriated growling of an angry lion.

And when at last they reached the trench, those farthest on the left of the advancing Britishers heard a machine gun sputter suddenly before them and saw a huge lion leap over the German parados with the body of a screaming Hun soldier between his jaws and vanish into the shadows of the night, while squatting upon a traverse to their left was Tarzan of the Apes with a machine gun before him with which he was raking the length of the German trenches.

The foremost Rhodesians saw something else-they saw a huge German officer emerge from a dugout just in rear of the ape-man. They saw him s.n.a.t.c.h up a discarded rifle with bayonet fixed and creep upon the apparently unconscious Tarzan. They ran forward, shouting warnings; but above the pandemonium of the trenches and the machine gun their voices could not reach him. The German leaped upon the parapet behind him-the fat hands raised the rifle b.u.t.t aloft for the cowardly downward thrust into the naked back and then, as moves Ara, the lightning, moved Tarzan of the Apes.

It was no man who leaped forward upon that Boche officer, striking aside the sharp bayonet as one might strike aside a straw in a baby's hand-it was a wild beast and the roar of a wild beast was upon those savage lips, for as that strange sense that Tarzan owned in common with the other jungle-bred creatures of his wild domain warned him of the presence behind him and he had whirled to meet the attack, his eyes had seen the corps and regimental insignia upon the other's blouse-it was the same as that worn by the murderers of his wife and his people, by the despoilers of his home and his happiness.

It was a wild beast whose teeth fastened upon the shoulder of the Hun-it was a wild beast whose talons sought that fat neck. And then the boys of the Second Rhodesian Regiment saw that which will live forever in their memories. They saw the giant ape-man pick the heavy German from the ground and shake him as a terrier might shake a rat-as Sabor, the lioness, sometimes shakes her prey. They saw the eyes of the Hun bulge in horror as he vainly struck with his futile hands against the ma.s.sive chest and head of his a.s.sailant. They saw Tarzan suddenly spin the man about and placing a knee in the middle of his back and an arm about his neck bend his shoulders slowly backward. The German's knees gave and he sank upon them, but still that irresistible force bent him further and further. He screamed in agony for a moment-then something snapped and Tarzan cast him aside, a limp and lifeless thing.

The Rhodesians started forward, a cheer upon their lips-a cheer that never was uttered-a cheer that froze in their throats, for at that moment Tarzan placed a foot upon the carca.s.s of his kill and, raising his face to the heavens, gave voice to the weird and terrifying victory cry of the bull ape.

Underlieutenant von Goss was dead.

Without a backward glance at the awe-struck soldiers Tarzan leaped the trench and was gone.

Chapter V

The Golden Locket

The little British army in East Africa, after suffering severe reverses at the hands of a numerically much superior force, was at last coming into its own. The German offensive had been broken and the Huns were now slowly and doggedly retreating along the railway to Tanga. The break in the German lines had followed the clearing of a section of their left-flank trenches of native soldiers by Tarzan and Numa, the lion, upon that memorable night that the ape-man had loosed a famishing man-eater among the superst.i.tious and terror-stricken blacks. The Second Rhodesian Regiment had immediately taken possession of the abandoned trench and from this position their flanking fire had raked contiguous sections of the German line, the diversion rendering possible a successful night attack on the part of the balance of the British forces.

Weeks had elapsed. The Germans were contesting stubbornly every mile of waterless, thorn-covered ground and clinging desperately to their positions along the railway. The officers of the Second Rhodesians had seen nothing more of Tarzan of the Apes since he had slain Underlieutenant von Goss and disappeared toward the very heart of the German position, and there were those among them who believed that he had been killed within the enemy lines.

"They may have killed him," a.s.sented Colonel Capell; "but I fancy they never captured the beggar alive."

Nor had they, nor killed him either. Tarzan had spent those intervening weeks pleasantly and profitably. He had ama.s.sed a considerable fund of knowledge concerning the disposition and strength of German troops, their methods of warfare, and the various ways in which a lone Tarmangani might annoy an army and lower its morale.

At present he was prompted by a specific desire. There was a certain German spy whom he wished to capture alive and take back to the British. When he had made his first visit to German headquarters, he had seen a young woman deliver a paper to the German general, and later he had seen that same young woman within the British lines in the uniform of a British officer. The conclusions were obvious-she was a spy.

And so Tarzan haunted German headquarters upon many nights hoping to see her again or to pick up some clew as to her whereabouts, and at the same time he utilized many an artifice whereby he might bring terror to the hearts of the Germans. That he was successful was often demonstrated by the s.n.a.t.c.hes of conversation he overheard as he prowled through the German camps. One night as he lay concealed in the bushes close beside a regimental headquarters he listened to the conversation of several Boche officers. One of the men reverted to the stories told by the native troops in connection with their rout by a lion several weeks before and the simultaneous appearance in their trenches of a naked, white giant whom they were perfectly a.s.sured was some demon of the jungle.

"The fellow must have been the same as he who leaped into the general's headquarters and carried off Schneider," a.s.serted one. "I wonder how he happened to single out the poor major. They say the creature seemed interested in no one but Schneider. He had von Kelter in his grasp, and he might easily have taken the general himself; but he ignored them all except Schneider. Him he pursued about the room, seized and carried off into the night. Gott knows what his fate was."

"Captain Fritz Schneider has some sort of theory," said another. "He told me only a week or two ago that he thinks he knows why his brother was taken-that it was a case of mistaken ident.i.ty. He was not so sure about it until von Goss was killed, apparently by the same creature, the night the lion entered the trenches. Von Goss was attached to Schneider's company. One of Schneider's men was found with his neck wrung the same night that the major was carried off and Schneider thinks that this devil is after him and his command-that it came for him that night and got his brother by mistake. He says Kraut told him that in presenting the major to Fraulein Kircher the former's name was no sooner spoken than this wild man leaped through the window and made for him."

Suddenly the little group became rigid-listening. "What was that?" snapped one, eyeing the bushes from which a smothered snarl had issued as Tarzan of the Apes realized that through his mistake the perpetrator of the horrid crime at his bungalow still lived-that the murderer of his wife went yet unpunished.

For a long minute the officers stood with tensed nerves, every eye riveted upon the bushes from whence the ominous sound had issued. Each recalled recent mysterious disappearances from the heart of camps as well as from lonely out-guards. Each thought of the silent dead he had seen, slain almost within sight of their fellows by some unseen creature. They thought of the marks upon dead throats-made by talons or by giant fingers, they could not tell which-and those upon shoulders and jugulars where powerful teeth had fastened and they waited with drawn pistols.

Once the bushes moved almost imperceptibly and an instant later one of the officers, without warning, fired into them; but Tarzan of the Apes was not there. In the interval between the moving of the bushes and the firing of the shot he had melted into the night. Ten minutes later he was hovering on the outskirts of that part of camp where were bivouacked for the night the black soldiers of a native company commanded by one Hauptmann Fritz Schneider. The men were stretched upon the ground without tents; but there were tents pitched for the officers. Toward these Tarzan crept. It was slow and perilous work, as the Germans were now upon the alert for the uncanny foe that crept into their camps to take his toll by night, yet the ape-man pa.s.sed their sentinels, eluded the vigilance of the interior guard, and crept at last to the rear of the officers' line.

Here he flattened himself against the ground close behind the nearest tent and listened. From within came the regular breathing of a sleeping man-one only. Tarzan was satisfied. With his knife he cut the tie strings of the rear flap and entered. He made no noise. The shadow of a falling leaf, floating gently to earth upon a still day, could have been no more soundless. He moved to the side of the sleeping man and bent low over him. He could not know, of course, whether it was Schneider or another, as he had never seen Schneider; but he meant to know and to know even more. Gently he shook the man by the shoulder. The fellow turned heavily and grunted in a thick guttural.

"Silence!" admonished the ape-man in a low whisper. "Silence-I kill."

The Hun opened his eyes. In the dim light he saw a giant figure bending over him. Now a mighty hand grasped his shoulder and another closed lightly about his throat.

"Make no outcry," commanded Tarzan; "but answer in a whisper my questions. What is your name?"

"Luberg," replied the officer. He was trembling. The weird presence of this naked giant filled him with dread. He, too, recalled the men mysteriously murdered in the still watches of the night camps. "What do you want?"

"Where is Hauptmann Fritz Schneider?" asked Tarzan, "Which is his tent?"

"He is not here," replied Luberg. "He was sent to Wilhelmstal yesterday."

"I shall not kill you-now," said the ape-man. "First I shall go and learn if you have lied to me and if you have your death shall be the more terrible. Do you know how Major Schneider died?"

Luberg shook his head negatively.

"I do," continued Tarzan, "and it was not a nice way to die-even for an accursed German. Turn over with your face down and cover your eyes. Do not move or make any sound."

The man did as he was bid and the instant that his eyes were turned away, Tarzan slipped from the tent. An hour later he was outside the German camp and headed for the little hill town of Wilhelmstal, the summer seat of government of German East Africa.

Fraulein Bertha Kircher was lost. She was humiliated and angry-it was long before she would admit it, that she, who prided herself upon her woodcraft, was lost in this little patch of country between the Pangani and the Tanga railway. She knew that Wilhelmstal lay southeast of her about fifty miles; but, through a combination of untoward circ.u.mstances, she found herself unable to determine which was southeast.

In the first place she had set out from German headquarters on a well-marked road that was being traveled by troops and with every reason to believe that she would follow that road to Wilhelmstal. Later she had been warned from this road by word that a strong British patrol had come down the west bank of the Pangani, effected a crossing south of her, and was even then marching on the railway at Tonda.

After leaving the road she found herself in thick bush and as the sky was heavily overcast she presently had recourse to her compa.s.s and it was not until then that she discovered to her dismay that she did not have it with her. So sure was she of her woodcraft, however, that she continued on in the direction she thought west until she had covered sufficient distance to warrant her in feeling a.s.sured that, by now turning south, she could pa.s.s safely in rear of the British patrol.

Nor did she commence to feel any doubts until long after she had again turned toward the east well south, as she thought, of the patrol. It was late afternoon-she should long since have struck the road again south of Tonda; but she had found no road and now she began to feel real anxiety.

Her horse had traveled all day without food or water, night was approaching and with it a realization that she was hopelessly lost in a wild and trackless country notorious princ.i.p.ally for its tsetse flies and savage beasts. It was maddening to know that she had absolutely no knowledge of the direction she was traveling-that she might be forging steadily further from the railway, deeper into the gloomy and forbidding country toward the Pangani; yet it was impossible to stop-she must go on.

Bertha Kircher was no coward, whatever else she may have been, but as night began to close down around her she could not shut out from her mind entirely contemplation of the terrors of the long hours ahead before the rising sun should dissipate the Stygian gloom-the horrid jungle night-that lures forth all the prowling, preying creatures of destruction.

She found, just before dark, an open meadow-like break in the almost interminable bush. There was a small clump of trees near the center and here she decided to camp. The gra.s.s was high and thick, affording feed for her horse and a bed for herself, and there was more than enough dead wood lying about the trees to furnish a good fire well through the night. Removing the saddle and bridle from her mount she placed them at the foot of a tree and then picketed the animal close by. Then she busied herself collecting firewood and by the time darkness had fallen she had a good fire and enough wood to last until morning.

From her saddlebags she took cold food and from her canteen a swallow of water. She could not afford more than a small swallow for she could not know how long a time it might be before she should find more. It filled her with sorrow that her poor horse must go waterless, for even German spies may have hearts and this one was very young and very feminine.

It was now dark. There was neither moon nor stars and the light from her fire only accentuated the blackness beyond. She could see the gra.s.s about her and the boles of the trees which stood out in brilliant relief against the solid background of impenetrable night, and beyond the firelight there was nothing.

The jungle seemed ominously quiet. Far away in the distance she heard faintly the boom of big guns; but she could not locate their direction. She strained her ears until her nerves were on the point of breaking; but she could not tell from whence the sound came. And it meant so much to her to know, for the battle-lines were north of her and if she could but locate the direction of the firing she would know which way to go in the morning.

In the morning! Would she live to see another morning? She squared her shoulders and shook herself together. Such thoughts must be banished-they would never do. Bravely she hummed an air as she arranged her saddle near the fire and pulled a quant.i.ty of long gra.s.s to make a comfortable seat over which she spread her saddle blanket. Then she un-strapped a heavy, military coat from the cantle of her saddle and donned it, for the air was already chill.

Seating herself where she could lean against the saddle she prepared to maintain a sleepless vigil throughout the night. For an hour the silence was broken only by the distant booming of the guns and the low noises of the feeding horse and then, from possibly a mile away, came the rumbling thunder of a lion's roar. The girl started and laid her hand upon the rifle at her side. A little shudder ran through her slight frame and she could feel the goose flesh rise upon her body.
