A simple plan for gaining entrance to the city had occurred to Tarzan, and now that darkness had fallen he set about to put it into effect. Its success hinged entirely upon the strength of the vines he had seen surmounting the wall toward the east. In this direction he made his way, while from out of the forest about him the cries of the flesh-eaters increased in volume and ferocity. A quarter of a mile intervened between the forest and the city wall-a quarter of a mile of cultivated land unrelieved by a single tree. Tarzan of the Apes realized his limitations and so he knew that it would undoubtedly spell death for him to be caught in the open s.p.a.ce by one of the great black lions of the forest if, as he had already surmised, Numa of the pit was a specimen of the forest lion of the valley.

He must, therefore, depend entirely upon his cunning and his speed, and upon the chance that the vine would sustain his weight.

He moved through the middle terrace, where the way is always easiest, until he reached a point opposite the vine-clad portion of the wall, and there he waited, listening and scenting, until he might a.s.sure himself that there was no Numa within his immediate vicinity, or, at least, none that sought him. And when he was quite sure that there was no lion close by in the forest, and none in the clearing between himself and the wall, he dropped lightly to the ground and moved stealthily out into the open.

The rising moon, just topping the eastern cliffs, cast its bright rays upon the long stretch of open garden beneath the wall. And, too, it picked out in clear relief for any curious eyes that chanced to be cast in that direction, the figure of the giant ape-man moving across the clearing. It was only chance, of course, that a great lion hunting at the edge of the forest saw the figure of the man halfway between the forest and the wall. Suddenly there broke upon Tarzan's ears a menacing sound. It was not the roar of a hungry lion, but the roar of a lion in rage, and, as he glanced back in the direction from which the sound came, he saw a huge beast moving out from the shadow of the forest toward him.

Even in the moonlight and at a distance Tarzan saw that the lion was huge; that it was indeed another of the black-maned monsters similar to Numa of the pit. For an instant he was impelled to turn and fight, but at the same time the thought of the helpless girl imprisoned in the city flashed through his brain and, without an instant's hesitation, Tarzan of the Apes wheeled and ran for the wall. Then it was that Numa charged.

Numa, the lion, can run swiftly for a short distance, but he lacks endurance. For the period of an ordinary charge he can cover the ground with greater rapidity possibly than any other creature in the world. Tarzan, on the other hand, could run at great speed for long distances, though never as rapidly as Numa when the latter charged.

The question of his fate, then, rested upon whether, with his start he could elude Numa for a few seconds; and, if so, if the lion would then have sufficient stamina remaining to pursue him at a reduced gait for the balance of the distance to the wall.

Never before, perhaps, was staged a more thrilling race, and yet it was run with only the moon and stars to see. Alone and in silence the two beasts sped across the moonlit clearing. Numa gained with appalling rapidity upon the fleeing man, yet at every bound Tarzan was nearer to the vine-clad wall. Once the ape-man glanced back. Numa was so close upon him that it seemed inevitable that at the next bound he should drag him down; so close was he that the ape-man drew his knife as he ran, that he might at least give a good account of himself in the last moments of his life.

But Numa had reached the limit of his speed and endurance. Gradually he dropped behind but he did not give up the pursuit, and now Tarzan realized how much hinged upon the strength of the untested vines.

If, at the inception of the race, only Goro and the stars had looked down upon the contestants, such was not the case at its finish, since from an embrasure near the summit of the wall two close-set black eyes peered down upon the two. Tarzan was a dozen yards ahead of Numa when he reached the wall. There was no time to stop and inst.i.tute a search for st.u.r.dy stems and safe handholds. His fate was in the hands of chance and with the realization he gave a final spurt and running catlike up the side of the wall among the vines, sought with his hands for something that would sustain his weight. Below him Numa leaped also.

Chapter XVIII

Among the Maniacs

As the lions swarmed over her protectors, Bertha Kircher shrank back in the cave in a momentary paralysis of fright super-induced, perhaps, by the long days of terrific nerve strain which she had undergone.

Mingled with the roars of the lions had been the voices of men, and presently out of the confusion and turmoil she felt the near presence of a human being, and then hands reached forth and seized her. It was dark and she could see but little, nor any sign of the English officer or the ape-man. The man who seized her kept the lions from her with what appeared to be a stout spear, the haft of which he used to beat off the beasts. The fellow dragged her from the cavern the while he shouted what appeared to be commands and warnings to the lions.

Once out upon the light sands of the bottom of the gorge objects became more distinguishable, and then she saw that there were other men in the party and that two half led and half carried the stumbling figure of a third, whom she guessed must be Smith-Oldwick.

For a time the lions made frenzied efforts to reach the two captives but always the men with them succeeded in beating them off. The fellows seemed utterly unafraid of the great beasts leaping and snarling about them, handling them much the same as one might handle a pack of obstreperous dogs. Along the bed of the old watercourse that once ran through the gorge they made their way, and as the first faint lightening of the eastern horizon presaged the coming dawn, they paused for a moment upon the edge of a declivity, which appeared to the girl in the strange light of the waning night as a vast, bottomless pit; but, as their captors resumed their way and the light of the new day became stronger, she saw that they were moving downward toward a dense forest.

Once beneath the over-arching trees all was again Cimmerian darkness, nor was the gloom relieved until the sun finally arose beyond the eastern cliffs, when she saw that they were following what appeared to be a broad and well-beaten game trail through a forest of great trees. The ground was unusually dry for an African forest and the underbrush, while heavily foliaged, was not nearly so rank and impenetrable as that which she had been accustomed to find in similar woods. It was as though the trees and the bushes grew in a waterless country, nor was there the musty odor of decaying vegetation or the myriads of tiny insects such as are bred in damp places.

As they proceeded and the sun rose higher, the voices of the arboreal jungle life rose in discordant notes and loud chattering about them. Innumerable monkeys scolded and screamed in the branches overhead, while harsh-voiced birds of brilliant plumage darted hither and thither. She noticed presently that their captors often cast apprehensive glances in the direction of the birds and on numerous occasions seemed to be addressing the winged denizens of the forest.

One incident made a marked impression on her. The man who immediately preceded her was a fellow of powerful build, yet, when a brilliantly colored parrot swooped downward toward him, he dropped upon his knees and covering his face with his arms bent forward until his head touched the ground. Some of the others looked at him and laughed nervously. Presently the man glanced upward and seeing that the bird had gone, rose to his feet and continued along the trail.

It was at this brief halt that Smith-Oldwick was brought to her side by the men who had been supporting him. He had been rather badly mauled by one of the lions; but was now able to walk alone, though he was extremely weak from shock and loss of blood.

"Pretty mess, what?" he remarked with a wry smile, indicating his b.l.o.o.d.y and disheveled state.

"It is terrible," said the girl. "I hope you are not suffering."

"Not as much as I should have expected," he replied, "but I feel as weak as a fool. What sort of creatures are these beggars, anyway?"

"I don't know," she replied, "there is something terribly uncanny about their appearance."

The man regarded one of their captors closely for a moment and then, turning to the girl asked, "Did you ever visit a madhouse?"

She looked up at him in quick understanding and with a horrified expression in her eyes. "That's it!" she cried.

"They have all the earmarks," he said. "Whites of the eyes showing all around the irises, hair growing stiffly erect from the scalp and low down upon the forehead-even their mannerisms and their carriage are those of maniacs."

The girl shuddered.

"Another thing about them," continued the Englishman, "that doesn't appear normal is that they are afraid of parrots and utterly fearless of lions."

"Yes," said the girl; "and did you notice that the birds seem utterly fearless of them-really seem to hold them in contempt? Have you any idea what language they speak?"

"No," said the man, "I have been trying to figure that out. It's not like any of the few native dialects of which I have any knowledge."

"It doesn't sound at all like the native language," said the girl, "but there is something familiar about it. You know, every now and then I feel that I am just on the verge of understanding what they are saying, or at least that somewhere I have heard their tongue before, but final recognition always eludes me."

"I doubt if you ever heard their language spoken," said the man. "These people must have lived in this out-of-the-way valley for ages and even if they had retained the original language of their ancestors without change, which is doubtful, it must be some tongue that is no longer spoken in the outer world."

At one point where a stream of water crossed the trail the party halted while the lions and the men drank. They motioned to their captives to drink too, and as Bertha Kircher and Smith-Oldwick, lying p.r.o.ne upon the ground drank from the clear, cool water of the rivulet, they were suddenly startled by the thunderous roar of a lion a short distance ahead of them. Instantly the lions with them set up a hideous response, moving restlessly to and fro with their eyes always either turned in the direction from which the roar had come or toward their masters, against whom the tawny beasts slunk. The men loosened the sabers in their scabbards, the weapons that had aroused Smith-Oldwick's curiosity as they had Tarzan's, and grasped their spears more firmly.

Evidently there were lions and lions, and while they evinced no fear of the beasts which accompanied them, it was quite evident that the voice of the newcomer had an entirely different effect upon them, although the men seemed less terrified than the lions. Neither, however, showed any indication of an inclination to flee; on the contrary the entire party advanced along the trail in the direction of the menacing roars, and presently there appeared in the center of the path a black lion of gigantic proportions. To Smith-Oldwick and the girl he appeared to be the same lion that they had encountered at the plane and from which Tarzan had rescued them. But it was not Numa of the pit, although he resembled him closely.

The black beast stood directly in the center of the trail lashing his tail and growling menacingly at the advancing party. The men urged on their own beasts, who growled and whined but hesitated to charge. Evidently becoming impatient, and in full consciousness of his might the intruder raised his tail stiffly erect and shot forward. Several of the defending lions made a half-hearted attempt to obstruct his pa.s.sage, but they might as well have placed themselves in the path of an express train, as hurling them aside the great beast leaped straight for one of the men. A dozen spears were launched at him and a dozen sabers leaped from their scabbards; gleaming, razor-edged weapons they were, but for the instant rendered futile by the terrific speed of the charging beast.

Two of the spears entering his body but served to further enrage him as, with demoniacal roars, he sprang upon the hapless man he had singled out for his prey. Scarcely pausing in his charge he seized the fellow by the shoulder and, turning quickly at right angles, leaped into the concealing foliage that flanked the trail, and was gone, bearing his victim with him.

So quickly had the whole occurrence transpired that the formation of the little party was scarcely altered. There had been no opportunity for flight, even if it had been contemplated; and now that the lion was gone with his prey the men made no move to pursue him. They paused only long enough to recall the two or three of their lions that had scattered and then resumed the march along the trail.

"Might be an everyday occurrence from all the effect it has on them," remarked Smith-Oldwick to the girl.

"Yes," she said. "They seem to be neither surprised nor disconcerted, and evidently they are quite sure that the lion, having got what he came for, will not molest them further."

"I had thought," said the Englishman, "that the lions of the Wamabo country were about the most ferocious in existence, but they are regular tabby cats by comparison with these big black fellows. Did you ever see anything more utterly fearless or more terribly irresistible than that charge?"

For a while, as they walked side by side, their thoughts and conversation centered upon this latest experience, until the trail emerging from the forest opened to their view a walled city and an area of cultivated land. Neither could suppress an exclamation of surprise.

"Why, that wall is a regular engineering job," exclaimed Smith-Oldwick.

"And look at the domes and minarets of the city beyond," cried the girl. "There must be a civilized people beyond that wall. Possibly we are fortunate to have fallen into their hands."

Smith-Oldwick shrugged his shoulders. "I hope so," he said, "though I am not at all sure about people who travel about with lions and are afraid of parrots. There must be something wrong with them."

The party followed the trail across the field to an arched gateway which opened at the summons of one of their captors, who beat upon the heavy wooden panels with his spear. Beyond, the gate opened into a narrow street which seemed but a continuation of the jungle trail leading from the forest. Buildings on either hand adjoined the wall and fronted the narrow, winding street, which was only visible for a short distance ahead. The houses were practically all two-storied structures, the upper stories flush with the street while the walls of the first story were set back some ten feet, a series of simple columns and arches supporting the front of the second story and forming an arcade on either side of the narrow thoroughfare.

The pathway in the center of the street was unpaved, but the floors of the arcades were cut stone of various shapes and sizes but all carefully fitted and laid without mortar. These floors gave evidence of great antiquity, there being a distinct depression down the center as though the stone had been worn away by the pa.s.sage of countless sandaled feet during the ages that it had lain there.

There were few people astir at this early hour, and these were of the same type as their captors. At first those whom they saw were only men, but as they went deeper into the city they came upon a few naked children playing in the soft dust of the roadway. Many they pa.s.sed showed the greatest surprise and curiosity in the prisoners, and often made inquiries of the guards, which the two a.s.sumed must have been in relation to themselves, while others appeared not to notice them at all.

"I wish we could understand their bally language," exclaimed Smith-Oldwick.
