Part 2

As these thoughts were commencing to oppress him, he became suddenly conscious of a vague change in the appearance of the terrain ahead. It was only an impression of unreality. The hills far away before him seemed to rise out of a great void, and it was as though between him and them there existed nothing. He might have been looking across an inland sea to distant, hazy shores--a waterless sea, for nowhere was there any suggestion of water--and then suddenly he came to a halt, startled, amazed. The rolling plateau ceased abruptly at his feet, and below him, stretching far to the distant hills, lay a great abyss--a mighty canyon similar to that which has made the gorge of the Colorado world-famous.

But here there was a marked difference. There were indications of erosion. The grim walls were scarred and water-worn. Towers and turrets and minarets, carved from the native granite, pointed upward from below, but they clung close to the canyon's wall, and just beyond them he could see the broad expanse of the floor of the canyon, which from his great height above it appeared as level as a billiard table. The scene held him in a hypnosis of wonderment and admiration as, at first swiftly and then slowly, his eyes encompassed the whole astounding scene.

Perhaps a mile below him lay the floor of the sunken canyon, the further wall of which he could but vaguely estimate to be somewhere between fifteen and twenty miles to the north, and this he realized was the lesser dimension of the canyon. Upon his right, to the east, and upon his left, to the west, he could see that the canyon extended to considerable distances--just how far he could not guess. He thought that to the east he could trace the wall that hemmed it upon that side, but from where he stood the entire extent of the canyon to the west was not visible, yet he knew that the floor that was visible to him must stretch fully twenty-five or thirty miles from east to west. Almost below him was a large lake or marsh that seemed to occupy the greater part of the east end of the canyon. He could see lanes of water winding through what appeared to be great growths of reeds and, nearer the northern shore, a large island. Three streams, winding ribbons far below, emptied into the lake, and in the far distance was another ribbon that might be a road. To the west the canyon was heavily wooded, and between the forest and the lake he saw moving figures of what he thought to be grazing game.

The sight below him aroused the enthusiasm of the explorer to its highest pitch. Here, doubtless, lay the secret of The Lost Tribe of the Wiramwazi and how well Nature had guarded this secret with stupendous barrier cliffs, aided by the superstitions of the ignorant black inhabitants of the outer slopes, was now easily understandable.

As far as he could see, the cliffs seemed sheer and impossible of descent, and yet he knew that he must find a way--that he would find a way down into that valley of enchantment.

Moving slowly along the rim he sought some foothold, however slight, where Nature had lowered her guard, but it was almost night and he had covered but a short distance before he found even a suggestion of hope that the canyon was hemmed at any point by other than unbroken cliffs, whose perpendicular faces rose at their lowest point fully a thousand feet above any possible foothold for a human being.

The sun had already set when he discovered a narrow fissure in the granite wall. Crumbled fragments of the mother rock had fallen into and partially filled it so that near the surface, at least, it offered a means of descent below the level of the cliff top, but in the gathering darkness he could not determine how far downward this rough and precarious pathway led.

He could see that below him the cliffs rose in terraced battlements to within a thousand feet of where he stood, and if the narrow fissure extended to the next terrace below him, he felt that the obstacles thereafter would present fewer difficulties than those that baffled him up to the present time--for while he would still have some four thousand feet to descend, the formation of the cliffs was much more broken at the foot of the first sheer drop and consequently might be expected to offer some avenues of descent of which an experienced mountain climber could take advantage.

Hungry and cold, he sat beneath the descending night, gazing down into the blackening void below. Presently, as the darkness deepened, he saw a light twinkling far below and then another and another and with each his excitement rose, for he knew that they marked the presence of man. In many places upon the marsh-like lake he saw the fires twinkling, and at a point which he took to mark the site of the island there were many lights.

What sort of men were they who tended these fires? Would he find them friendly or hostile? Were they but another tribe of African blacks, or could it be that the old legend was based upon truth and that far below him white men of The Lost Tribe cooked their evening meals above those tantalizing fires of mystery?

What was that? Von Harben strained his ears to catch the faint suggestion of a sound that arose out of the shadowy abyss below--a faint, thin sound that barely reached his ears, but he was sure that he could not be mistaken--the sound was the voices of men.

And now from out of the valley came the scream of a beast and again a roar that rumbled upward like distant thunder. To the music of these sounds, von Harben finally succumbed to exhaustion; sleep for the moment offering him relief from cold and hunger.

When morning came he gathered wood from the stunted trees near by and built a fire to warm himself. He had no food, nor all the previous day since he had reached the summit had he seen any sign of a living creature other than the game a mile beneath him on the verdant meadows of the canyon bottom.

He knew that he must have food and have it soon and food lay but a mile away in one direction. If he sought to circle the canyon in search of an easier avenue of descent, he knew that he might not find one in the hundred miles or more that he must travel. Of course he might turn back. He was sure that he could reach the base of the outer slopes of the Wiramwazi, where he knew that game might be found before exhaustion overcame him, but he had no mind to turn back and the thought of failure was only a vague suggestion that scarcely ever rose above the threshold of his conscious mind.

Having warmed himself before the fire, he turned to examine the fissure by the full light of day. As he stood upon its brink he could see that it extended downward for several hundred feet, but there it disappeared. However, he was by no means sure that it ended, since it was not a vertical cleft, but tilted slightly from the perpendicular.

From where he stood he could see that there were places in the fissure where descent would be just possible, though it might be very difficult to reascend. He knew, therefore, that should he reach the bottom of the fissure and find that further descent was impossible he would be caught in a trap from which there might be no escape.

Although he felt as fit and strong as ever, he realized perfectly that the contrary was the fact and that his strength must be ebbing and that it would continue to ebb still more rapidly the longer that he was forced to expend it in arduous efforts to descend the cliff and without any possibility of rebuilding it with food.

Even to Erich von Harben, young, self-confident and enthusiastic, his next step seemed little better than suicidal. To another the mere idea of attempting the descent of these towering cliffs would have seemed madness, but in other mountains von Harben had always found a way, and with this thin thread upon which to hang his hopes he faced the descent into the unknown. Now he was just about to lower himself over the edge of the fissure when he heard the sounds of footsteps behind him. Wheeling quickly, he drew his Luger.

_Chapter Three_

Little Nkima came racing through the tree tops, jabbering excitedly, and dropped to the knee of Tarzan of the Apes where the latter lay stretched upon the great branch of a jungle giant, his back against the rough bole, where he was lying up after making a kill and feeding.

"Gomangani! Gomangani!" shrilled Nkima. "They come! They come!"

"Peace," said Tarzan. "You are a greater nuisance than all the Gomangani in the jungle."

"They will kill little Nkima," cried the monkey. "They are strange Gomangani, and there are no Tarmangani among them."

"Nkima thinks everything wants to kill him," said Tarzan, "and yet he has lived many years and is not dead yet."

"Sabor and Sheeta and Numa, the Gomangani, and Histah the snake like to eat poor little Nkima," wailed the monkey. "That is why he is afraid."

"Do not fear, Nkima," said the ape-man. "Tarzan will let no one hurt you."

"Go and see the Gomangani," urged Nkima. "Go and kill them. Nkima does not like the Gomangani."

Tarzan arose leisurely. "I go," he said. "Nkima may come or he may hide in the upper terraces."

"Nkima is not afraid," blustered the little monkey. "He will go and fight the Gomangani with Tarzan of the Apes," and he leaped to the back of the ape-man and clung there with his arms about the bronzed throat, from which point of vantage he peered fearfully ahead, first over the top of one broad shoulder and then over the top of the other.

Tarzan swung swiftly and quietly through the trees toward a point where Nkima had discovered the blacks, and presently he saw below him some score of natives straggling along the jungle trail. A few of them were armed with rifles and all carried packs of various sizes--such packs as Tarzan knew must belong to the equipment of a white man.

The Lord of the Jungle hailed them and, startled, the blacks halted, looking up fearfully.

"I am Tarzan of the Apes. Do not be afraid," Tarzan reassured them, and simultaneously he dropped lightly to the trail among them, but as he did so Nkima leaped frantically from his shoulders and scampered swiftly to a high branch far above, where he sat chattering and scolding, entirely forgetful of his vain boasting of a few moments before.

"Where is your master?" demanded Tarzan.

The blacks looked sullenly at the ground, but did not reply.

"Where is the Bwana, von Harben?" Tarzan insisted.

A tall black standing near fidgeted uneasily. "He is dead," he mumbled.

"How did he die?" asked Tarzan.

Again the black hesitated before replying. "A bull elephant that he had wounded killed him," he said at last.

"Where is his body?"

"We could not find it."

"Then how do you know that he was killed by a bull elephant?" demanded the ape-man.

"We do not know," spoke up another black. "He went away from camp and did not return."

"There was an elephant about and we thought that it had killed him," said the first black.

"You are not speaking true words," said Tarzan.

"I shall tell you the truth," said a third black. "Our Bwana ascended the slopes of the Wiramwazi and the spirits of the dead being angry seized him and carried him away."

"I shall tell you the truth," said Tarzan. "You have deserted your master and run away, leaving him alone in the forest."

"We were afraid," said the third black. "We warned him not to ascend the slopes of the Wiramwazi. We begged him to turn back. He would not listen to us, and the spirits of the dead carried him away."

"How long ago was that?" asked the ape-man.

"Six, seven, perhaps ten marchings. I do not remember."

"Where was he when you last saw him?"

As accurately as they could the blacks described the location of their last camp upon the slopes of the Wiramwazi.

"Go your way back to your own villages in the Urambi country. I shall know where to find you if I want you. If your Bwana is dead, you shall be punished," and swinging into the branches of the lower terrace, Tarzan disappeared from the sight of the unhappy blacks in the direction of the Wiramwazi, while Nkima, screaming shrilly, raced through the trees to overtake him.

From his conversation with the deserting members of von Harben's safari, Tarzan was convinced that the young man had been traitorously abandoned and that in all likelihood he was making his way alone back upon the trail of the deserters.

Not knowing Erich von Harben, Tarzan could not have guessed that the young man would push on alone into the unknown and forbidding depths of the Wiramwazi, but assumed on the contrary that he would adopt the more prudent alternative and seek to overtake his men as rapidly as possible. Believing this, the ape-man followed back along the trail of the blacks, expecting momentarily to meet von Harben.

This plan greatly reduced his speed, but even so he traveled with so much greater rapidity than the blacks that he came to the slopes of the Wiramwazi upon the third day after he had interviewed the remnants of von Harben's safari.

It was with great difficulty that he finally located the point at which von Harben had been abandoned by his men, as a heavy rain and wind-storm had obliterated the trail, but at last he stumbled upon the tent, which had blown down, but nowhere could he see any signs of von Harben's trail.

Not having come upon any signs of the white man in the jungle or any indication that he had followed his fleeing safari, Tarzan was forced to the conclusion that if von Harben was not indeed dead he must have faced the dangers of the unknown alone and now be either dead or alive somewhere within the mysterious fastnesses of the Wiramwazi.

"Nkima," said the ape-man, "the Tarmangani have a saying that when it is futile to search for a thing, it is like hunting for a needle in a haystack. Do you believe, Nkima, that in this great mountain range we shall find our needle?"

"Let us go home," said Nkima, "where it is warm. Here the wind blows and up there it is colder. It is no place for little Manu, the monkey."

"Nevertheless, Nkima, there is where we are going."

The monkey looked up toward the frowning heights above. "Little Nkima is afraid," he said. "It is in such places that Sheeta, the panther, lairs."

Ascending diagonally and in a westerly direction in the hope of crossing von Harben's trail, Tarzan moved constantly in the opposite direction from that taken by the man he sought. It was his intention, however, when he reached the summit, if he had in the meantime found no trace of von Harben, to turn directly eastward and search at a higher altitude in the opposite direction. As he proceeded, the slope became steeper and more rugged until at one point near the western end of the mountain mass he encountered an almost perpendicular barrier high up on the mountainside along the base of which he picked his precarious way among loose bowlders that had fallen from above. Underbrush and stunted trees extended at different points from the forest below quite up to the base of the vertical escarpment.

So engrossed was the ape-man in the dangerous business of picking his way along the mountainside that he gave little heed to anything beyond the necessities of the trail and his constant search for the spoor of von Harben, and so he did not see the little group of black warriors that were gazing up at him from the shelter of a clump of trees far down the slope, nor did Nkima, usually as alert as his master, have eyes or ears for anything beyond the immediate exigencies of the trail. Nkima was unhappy. The wind blew and Nkima did not like the wind. All about him he smelled the spoor of Sheeta, the panther, while he considered the paucity and stunted nature of the few trees along the way that his master had chosen. From time to time he noted, with sinking heart, ledges just above them from which Sheeta might spring down upon them; and the way was a way of terror for little Nkima.

Now they had come to a particularly precarious point upon the mountainside. A sheer cliff rose above them on their right and at their left the mountainside fell away so steeply that as Tarzan advanced his body was pressed closely against the granite face of the cliff as he sought a foothold upon the ledge of loose rubble. Just ahead of them the cliff shouldered out boldly against the distant skies. Perhaps beyond that clear-cut corner the going might be better. If it should develop that it was worse, Tarzan realized that he must turn back.

At the turn where the footing was narrowest a stone gave beneath Tarzan's foot, throwing him off his balance for an instant and at that same instant Nkima, thinking that Tarzan was falling, shrieked and leaped from his shoulder, giving the ape-man's body just the impetus that was required to overbalance it entirely.

The mountainside below was steep, though not perpendicular, and if Nkima had not pushed the ape-man outward he doubtless would have slid but a short distance before being able to stay his fall, but as it was he lunged headforemost down the embankment, rolling and tumbling for a short distance over the loose rock until his body was brought to a stop by one of the many stunted trees that clung tenaciously to the wind-swept slope.

Terrified, Nkima scampered to his master's side. He screamed and chattered in his ear and pulled and tugged upon him in an effort to raise him, but the ape-man lay motionless, a tiny stream of blood trickling from a cut on his temple into his shock of black hair.

As Nkima mourned, the black warriors, who had been watching them from below, clambered quickly up the mountainside toward him and his helpless master.

_Chapter Four_

As Erich von Harben turned to face the thing that he had heard approaching behind him, he saw a negro armed with a rifle coming toward him.

"Gabula!" exclaimed the white man, lowering his weapon. "What are you doing here?"

"Bwana," said the black, "I could not desert you. I could not leave you to die alone at the hands of the spirits that dwell upon these mountains."

Von Harben eyed the negro incredulously. "But if you believe that, Gabula, are you not afraid that they will kill you, too?"

"I expect to die, Bwana," replied Gabula. "I cannot understand why you were not killed the first night or the second night. We shall both surely be killed tonight."

"And yet you followed me! Why?"

"You have been kind to me, Bwana," replied the black. "Your father has been kind to me. When the others talked they filled me with fear and when they ran away I went with them, but I have come back. There was nothing else that I could do, was there?"

"No, Gabula. For you or for me there would have been nothing else to do, as we see such things, but as the others saw them they found another thing to do and they did it."

"Gabula is not as the others," said the black, proudly. "Gabula is a Batoro."

"Gabula is a brave warrior," said von Harben. "I do not believe in spirits and so there was no reason why I should be afraid, but you and all your people do believe in them and so it was a very brave thing for you to come back, but I shall not hold you. You may return, Gabula, with the others."

"Yes?" Gabula exclaimed eagerly. "The Bwana is going back? That will be good. Gabula will go back with him."

"No, I am going down into that canyon," said von Harben, pointing over the rim.

Gabula looked down, surprise and wonder reflected by his wide eyes and parted lips.

"But, Bwana, even if a human being could find a way down these steep cliffs, where there is no place for either hand or foot, he would surely be killed the moment he reached the bottom, for this indeed must be the Land of the Lost Tribe where the spirits of the dead live in the heart of the Wiramwazi."

"You do not need to come with me, Gabula," said von Harben. "Go back to your people."

"How are you going to get down there?" demanded the black.

"I do not know just how, or where, or when. Now I am going to descend as far along this fissure as I can go. Perhaps I shall find my way down here, perhaps not."

"But suppose there is no foothold beyond the fissure?" asked Gabula.

"I shall have to find footing."

Gabula shook his head. "And if you reach the bottom, Bwana, you are right about the spirits and there are none or they do not kill you, how will you get out again?"

Von Harben shrugged his shoulders and smiled. Then he extended his hand. "Good-by, Gabula," he said. "You are a brave man."

Gabula did not take the offered hand of his master. "I am going with you," he said, simply.

"Even though you realize that should we reach the bottom alive we may never be able to return?"

"Yes."

"I cannot understand you, Gabula. You are afraid and I know that you wish to return to the village of your people. Then why do you insist on coming with me when I give you leave to return home?"

"I have sworn to serve you, Bwana, and I am a Batoro," replied Gabula.

"And I can only thank the Lord that you are a Batoro," said von Harben, "for the Lord knows that I shall need help before I reach the bottom of this canyon, and we must reach it, Gabula, unless we are content to die by starvation."

"I have brought food," said Gabula. "I knew that you might be hungry and I brought some of the food that you like," and, unrolling the small pack that he carried, he displayed several bars of chocolate and a few packages of concentrated food that von Harben had included among his supplies in the event of an emergency.

To the famished von Harben, the food was like manna to the Israelites, and he lost no time in taking advantage of Gabula's thoughtfulness. The sharp edge of his hunger removed, von Harben experienced a feeling of renewed strength and hopefulness, and it was with a light heart and a buoyant optimism that he commenced the descent into the canyon. Gabula's ancestry, stretching back through countless generations of jungle-dwelling people, left him appalled as he contemplated the frightful abyss into which his master was leading him, but so deeply had he involved himself by his protestations of loyalty and tribal pride that he followed von Harben with no outward show of the real terror that was consuming him.

The descent through the fissure was less difficult than it had appeared from above. The tumbled rocks that had partially filled it gave more than sufficient footing and in only a few places was assistance required, and it was at these times that von Harben realized how fortunate for him had been Gabula's return.

When at last they reached the bottom of the cleft they found themselves, at its outer opening, flush with the face of the cliff and several hundred feet below the rim. This was the point beyond which von Harben had been unable to see and which he had been approaching with deep anxiety, since there was every likelihood that the conditions here might put a period to their further descent along this route.

Creeping over the loose rubble in the bottom of the fissure to its outer edge, von Harben discovered a sheer drop of a hundred feet to the level of the next terrace and his heart sank. To return the way they had come was, he feared, a feat beyond their strength and ingenuity, for there had been places down which one had lowered the other only with the greatest difficulty, which would be practically unscalable on the return journey.

It being impossible to ascend and as starvation surely faced them where they were, there was but one alternative. Von Harben lay upon his belly, his eyes at the outer edge of the fissure, and, instructing Gabula to hold tightly to his ankles, he wormed himself forward until he could scan the entire face of the cliff below him to the level of the next terrace.

A few feet from the level on which he lay he saw that the fissure lay open again to the base of the cliff, its stoppage at the point where they were having been caused by a large fragment of rock that had wedged securely between the sides of the fissure, entirely choking it at this point.
