As she came into the open her pumps commenced to expel the air from the three lower tanks and at the same time a portion of her excess water ballast was slowly discharged, and almost immediately the huge ship rose slowly and gracefully from the ground.
The entire personnel of the ship’s company during the test flight was the same that had been selected for the expedition.
Zuppner, who had been chosen as, captain, had been in charge of the construction of the ship and had a considerable part in its designing. There were two mates, Von Horst and Dorf, who had been officers in the Imperial air forces, as also had the navigator, Lieutenant Hines. In addition to these there were twelve engineers and eight mechanics, a negro cook and two Filipino cabin-boys.
Tarzan was commander of the expedition, with Jason Gridley as his lieutenant, while the fighting men of the ship consisted of Muviro and nine of his Waziri warriors.
As the ship rose gracefully above the city, Zuppner, who was at the controls, could scarce restrain his enthusiasm.
“The sweetest thing I ever saw!” he exclaimed. “She responds to the lightest touch.”
“I am not surprised at that,” said Hines; “I knew she’d do it. Why we’ve got twice the crew we need to handle her.”
“There you go again, Lieutenant,” said Tarzan, laughing; “but do not think that my insistence upon a large crew was based upon any lack of confidence in the ship. We are going into a strange world. We may be gone a long time. If we reach our destination we shall have fighting, as each of you men who volunteered has been informed many times, so that while we may have twice as many men as we need for the trip in., we may yet find ourselves short handed on the return journey, for not all of us will return.”
“I suppose you are right.” said Hines; “but with the feel of this ship permeating me and the quiet peacefulness of the scene below, danger and death seem remote.”
“I hope they are,” returned Tarzan, “and I hope that we shall return with every man that goes out with us, but I believe in being prepared and to that end Gridley and I have been studying navigation and we want you to give us a chance at some practical experience before we reach our destination.”
Zuppner laughed. “They have you marked already, Hines.” he said.
The Lieutenant grinned. “I’ll teach them all I know,” he said; “but I’ll bet the best dinner that can be served in Berlin that if this ship returns I’ll still be her navigator.”
“That is a case of heads-I-win, tails-you-lose,” said Gridley.
“And to return to the subject of preparedness,” said Tarzan, “I am going to ask you to let my Waziri help the mechanics and engineers. They are highly intelligent men, quick to learn, and if some calamity should overtake us we cannot have too many men familiar with the engines and other machinery of the ship.”
“You are right,” said Zuppner, “and I shall see that it is done.”
The great, shining ship sailed majestically north; Ravensburg fell astern and half an hour later the somber gray ribbon of the Danube lay below them.
The longer they were in the air the more enthusiastic Zuppner became. “I had every confidence in the successful outcome of the trial flight,” he said; “but I can assure you that I did not look for such perfection as I find in this ship. It marks a new era in aeronautics, and I am convinced that long before we cover the four hundred miles to Hamburg that we shall have established the entire air worthiness of the O-220 to the entire satisfaction of each of us.”
“To Hamburg and return to Friedrichshafen was to have been the route of the trial trip,” said Tarzan, “but why turn back at Hamburg?”
The others turned questioning eyes upon him as the purport of his query sank home.
“Yes, why?” demanded Gridley.
Zuppner shrugged his shoulders. “We are fully equipped and provisioned,” he said.
“Then why waste eight hundred miles in returning to Friedrichshafen?” demanded Hines.
“If you are all agreeable we shall continue on toward the north,” said Tarzan. And so it was that the trial trip of the O-220 became an actual start upon its long journey toward the interior of the earth, and the secrecy that was desired for the expedition was insured.
The plan had been to follow the Tenth Meridian east of Greenwich north to the pole. But to avoid attracting unnecessary notice a slight deviation from this course was found desirable, and the ship passed to the west of Hamburg and out across the waters of the North Sea, and thus due north, passing to the west of Spitsbergen and out across the frozen polar wastes.
Maintaining an average cruising speed of about 75 miles per hour, the O-220 reached the vicinity of the north pole about midnight of the second day, and excitement ran high when Hines announced that in accordance with his calculation they should be directly over the pole. At Tarzan’s suggestion the ship circled slowly at an altitude of a few hundred feet above the rough, snow-covered ice.
“We ought to be able to recognize it by the Italian flags,” said Zuppner, with a smile. But if any reminders of the passage of the Norge remained below them, they were effectually hidden by the mantle of many snows.
The ship made a single circle above the desolate ice pack before she took up her southerly course along the 170th East Meridian.
From the moment that the ship struck south from the pole Jason Gridley remained constantly with Hines and Zuppner eagerly and anxiously watching the instruments, or gazing down upon the bleak landscape ahead. It was Gridley’s belief that the north polar opening lay in the vicinity of 85 north latitude and 170 east longitude. Before him were compass, aneroids, bubble statoscope, air speed indicator, inclinometers, rise and fall indicator, bearing plate, clock and thermometers; but the instrument that commanded his closest attention was the compass, for Jason Gridley held a theory and upon the correctness of it depended their success in finding the north polar opening.
For five hours the ship flew steadily toward the south, when she developed an apparent tendency to fall off toward the west.
“Hold her steady, Captain,” cautioned Gridley, “for if I am correct we are now going over the lip of the polar opening, and the deviation is in the compass only and not in our course. The further we go along this course the more erratic the compass will become and if we were presently to move upward, or in other words, straight out across the polar opening toward its center, the needle would spin erratically in a circle. But we could not reach the center of the polar opening because of the tremendous altitude which this would require. I believe that we are now on the eastern verge of the opening and if whatever deviation from the present course you make is to the starboard we shall slowly spiral downward into Pellucidar, but your compass will be useless for the next four to six hundred miles.”
“Zuppner shook his head, dubiously. “If this weather holds, we may be able to do it,” he said, “but if it commences to blow I doubt my ability to keep any sort of a course if I am not to follow the compass.”
“Do the best you can,” said Gridley, “and when in doubt put her to starboard.”
So great was the nervous strain upon all of them that for hours at a time scarcely a word was exchanged.
“Look!” exclaimed Hines suddenly. “There is open water just ahead of us.”
“That, of course, we might expect,” said Zuppner, “even if, there is no polar opening, and you know that I have been skeptical about that ever since Gridley first explained his theory to me.”
“I think,” said Gridley, with a smile, “that really I am the only one in the party who has had any faith at all in the theory, but please do not call it my theory for it is not, and even I should not have been surprised had the theory proven to be a false one. But if any of you has been watching the sun for the last few hours, I think that you will have to agree with me that even though there may be no polar opening into an inner world, there must be a great depression at this point in the earth’s crust and that we have gone down into it for a considerable distance, for you will notice that the midnight sun is much lower than it should be and that the further we continue upon this course the lower it drops—eventually it will set completely, and if I am not much mistaken we shall soon see the light of the eternal noonday sun of Pellucidar.”
Suddenly the telephone rang and Hines put the receiver to his ear. “Very good, sir,” he said, after a moment, and hung up. “It was Von Horst, Captain, reporting from the observation cabin. He has sighted land dead ahead.”
“Land!” exclaimed Zuppner. “The only land our chart shows in this direction is Siberia.”
“Siberia lies over a thousand miles south of 85, and we cannot be over three hundred miles south of 85,” said Gridley.
“Then we have either discovered a new arctic land, or we are approaching the northern frontiers of Pellucidar,” said Lieutenant Hines.
“And that is just what we are doing,” said Gridley.
“Look at your thermometer.” “The devil!” exclaimed Zuppner. “It is only twenty degrees above zero Fahrenheit.” “You can see the land plainly now,” said Tarzan. “It looks desolate enough, but there are only little patches of snow here and there.” “This corresponds with the land Innes described north of Korsar,” said Gridley.
Word was quickly passed around the ship to the other officers and the crew that there was reason to believe that the land below them was Pellucidar. Excitement ran high, and every man who could spare a moment from his duties was aloft on the walking-way, or peering through portholes for a glimpse of the inner world.
Steadily the O-220 forged southward and just as the rim of the midnight sun disappeared from view below the horizon astern, the glow of Pellucidar’s central sun was plainly visible ahead.
The nature of the landscape below was changing rapidly. The barren land had fallen astern, the ship had crossed a range of wooded hills and now before it lay a great forest that stretched on and on seemingly curving upward to be lost eventually in the haze of the distance. This was indeed Pellucidar—the Pellucidar of which Jason Gridley had dreamed.
Beyond the forest lay a rolling plain dotted with clumps of trees, a well-watered plain through which wound numerous streams, which emptied into a large river at its opposite side.
Great herds of game were grazing in the open pasture land and nowhere was there sight of man.
“This looks like heaven to me,” said Tarzan of the Apes. “Let us land, Captain.”
Slowly the great ship came to earth as air was taken into the lower vacuum tanks.
Short ladders were run out, for the bottom of the cabin was only six feet above the ground, and presently the entire ship’s company, with the exception of a watch of an officer and two men, were knee deep in the lush grasses of Pellucidar.
“I thought we might get some fresh meat,” said Tarzan, “but the ship has frightened all the game away.”
“From the quantity of it I saw, we shall not have to go far to bag some,” said Dorf.
“What we need most right now, however, is rest,” said Tarzan. “For weeks every man has been working at high pitch in completing the preparation for the expedition and I doubt if one of us has had over two hours sleep in the last three days. I suggest that we remain here until we are all thoroughly rested and then take up a systematic search for the city of Korsar.”
The plan met with general approval and preparations were made for a stay of several days.
“I believe,” said Gridley to Captain Zuppner, “that it would be well to issue strict orders that no one is to leave the ship, or rather its close vicinity, without permission from you and that no one be allowed to venture far afield except in parties commanded by an officer, for we have every assurance that we shall meet with savage men, and far more savage beasts everywhere within Pellucidar.”
“I hope that you will except me from that order,” said Tarzan, smiling.
“I believe that you can take care of yourself in any country,” said Zuppner.
“And I can certainly hunt to better effect alone than I can with a party,” said the ape-man.
“In any event,” continued Zuppner, “the order comes from you as commander, and no one will complain if you exempt yourself from its provisions since I am sure that none of the rest of us is particularly anxious to wander about Pellucidar alone.”
Officers and men, with the exception of the watch, which changed every four hours, slept the clock around.
Tarzan of the Apes was the first to complete his sleep and leave the ship. He had discarded the clothing that had encumbered and annoyed him since he had left his own African jungle to join in the preparation of the O-220, and it was no faultlessly attired Englishman that came from the cabin and dropped to the ground below, but instead an almost naked and primitive warrior, armed with hunting knife, spear, a bow and arrows, and the long rope which Tarzan always carried, for in the hunt he preferred the weapons of his youth to the firearms of civilization.
Lieutenant Dorf, the only officer on duty at the time, saw him depart and watched with unfeigned admiration as the black-haired jungle lord moved across the open plain and disappeared in the forest.
There were trees that were familiar to the eyes of the ape-man, and trees such as he had never seen before, but it was a forest and that was enough to lure Tarzan of the Apes and permit him to forget the last few weeks that had been spent amidst the distasteful surroundings of civilization. He was happy to be free from the ship, too, and, while he liked all his companions, he was yet glad to be alone.
In the first flight of his new-found freedom Tarzan was like a boy released from school. Unhampered by the hated vestments of civilization, out of sight of anything that might even remotely remind him of the atrocities with which man scars the face of nature, he filled his lungs with the free air of Pellucidar, leaped into a nearby tree and swung away through the forest, his only concern for the moment the joyousness of exultant vitality and life. On he sped through the primeval forest of’ Pellucidar. Strange birds, startled by his swift and silent passage, flew screaming from his path, and strange beasts slunk to cover beneath him. But Tarzan did not care; he was not hunting; he was not even searching for the new in this new world. For the moment he was only living.
While this mood dominated him Tarzan gave no thought to the passage of time any more than he had given thought to the timelessness of Pellucidar, whose noonday sun, hanging perpetually at zenith, gives a lie to us of the outer crust who rush frantically through life in mad and futile effort to beat the earth in her revolutions. Nor did Tarzan reckon upon distance or direction, for such matters were seldom the subjects of conscious consideration upon the part of the ape-man, whose remarkable ability to meet every and any emergency he unconsciously attributed to powers that lay within himself, not stopping to consider that in his own jungle he relied upon the friendly sun and moon and stars as guides by day and night, and to the myriad familiar things that spoke to him in a friendly, voiceless language that only the jungle people can interpret.
As his mood changed Tarzan reduced his speed, and presently he dropped to the ground in a well-marked game trail. Now he let his eyes take in the new wonders all about him. He noticed the evidences of great age as betokened by the enormous size of the trees and the hoary stems of the great vines that clung to many of them—suggestions of age that made his own jungle seem modem—and be marveled at the gorgeous flowers that bloomed in riotous profusion upon every hand, and then of a sudden something gripped him about the body and snapped him high into the air.
Tarzan of the Apes had nodded. His mind occupied with the wonders of this new world had permitted a momentary relaxation of that habitual wariness that distinguishes creatures of the wild.
Almost in the instant of its occurrence the ape-man realized that what had befallen him. Although he could easily imagine its disastrous sequel, the suggestion of a smile touched his lips—a rueful smile—and one that was perhaps tinged with disgust for himself, for Tarzan of the Apes had been caught in as primitive a snare as was ever laid for unwary beasts.
A rawhide noose, attached to the downbent limb of an overhanging tree, had been buried in the trail along which he had been passing and he had struck the trigger—that was the whole story. But its sequel might have had less unfortunate possibilities had the noose not pinioned his arms to his sides as it closed about him.
He hung about six feet above the trail, caught securely about the hips, the noose imprisoning his arms between elbows and wrists and pinioning them securely to his sides. And to add to his discomfort and helplessness, he swung head downward, spinning dizzily like a human plumb-bob.
He tried to draw an arm from the encircling noose so that he might reach his hunting knife and free himself, but the weight of his body constantly drew the noose more tightly about him and every effort upon his part seemed but to strengthen the relentless grip of the rawhide that was pressing deep into his flesh.
He knew that the snare meant the presence of men and that doubtless they would soon come to inspect their noose, for his own knowledge of primitive hunting taught him that they would not leave their snares long untended, since in the event of a catch, if they would have it at all, they must claim it soon lest it fall prey to carnivorous beasts or birds. He wondered what sort of people they were and if he might not make friends with them, but whatever they were he hoped that they would come before the beasts of prey came. And while such thoughts were running through his mind, his keen ears caught the sound of approaching footsteps, but they were not the steps of men. Whatever was approaching was approaching across the wind and he could detect no scent spoor; nor, upon the other hand, he realized, could the beast scent him. It was coming leisurely and as it neared him, but before it came in sight along the trail, he knew that it was a hoofed animal and, therefore, that he had little reason to fear its approach unless, indeed, it might prove to be some strange Pellucidarian creature with characteristics entirely unlike any that he knew upon the outer crust.
But even as he permitted these thoughts partially to reassure him, there came strongly to his nostrils a scent that always caused the short hairs upon his head to rise, not in fear but in natural reaction to the presence of an hereditary enemy. It was not an odor that he had ever smelled before. It was not the scent spoor of Numa the lion, nor Sheeta the leopard, but it was the scent spoor of some sort of great cat. And now he could hear its almost silent approach through the underbrush and he knew that it was coming down toward the trail, lured either by knowledge of his presence or by that of the beast whose approach Tarzan had been awaiting.
It was the latter who came first into view—a great ox-like animal with wide-spread horns and shaggy coat—a huge bull that advanced several yards along the trail after Tarzan discovered it before it saw the ape-man dangling in front of it. It was the thag of Pellucidar, the Bos Primigenus of the paleontologist of the outer crust, a long extinct progenitor of the bovine races of our own world.
For a moment it stood eyeing the man dangling in its path.
Tarzan remained very quiet. He did not wish to frighten it away for he realized that one of them must be the prey of the carnivore sneaking upon them, but if be expected the thag to be frightened he soon realized his error in judgment for, uttering low grumblings, the great bull pawed the earth with a front foot, and then, lowering his massive horns, gored it angrily, and the ape-man knew that he was working his short temper up to charging pitch; nor did it seem that this was to take long for already he was advancing menacingly to the accompaniment of thunderous bellowing. His tail was up and his head down as he broke into the trot that precluded the charge.
The ape-man realized that if he was ever struck by those massive horns or that heavy bead, his skull would be crushed like an eggshell.
The dizzy spinning that had been caused by the first stretching of the rawhide to his weight had lessened to a gentle turning motion; so that sometimes he faced the thag and sometimes in the opposite direction. The utter helplessness of his position galled the ape-man and gave him more concern than any consideration of impending death. From childhood he had walked hand in hand with the Grim Reaper and he had looked upon death in so many forms that it held no terror for him. He knew that it was the final experience of all created things, that it must as inevitably come to him as to others and while he loved life and did not wish to die, its mere approach induced within him no futile hysteria. But to die without a chance to fight for life was not such an end as Tarzan of the Apes would have chosen. And now, as his body slowly revolved and his eyes were turned away from the charging thag, his heart sank at the thought that he was not even to be vouchsafed the meager satisfaction of meeting death face to face.
In the brief instant that he waited for the impact, the air was rent by as horrid a scream as had ever broken upon the ears of the ape-man and the bellowing of the bull rose suddenly to a higher pitch and mingled with that other awesome sound.
Once more the dangling body of the ape-man revolved and his eyes fell upon such a scene as had not been vouchsafed to men of the outer world for countless ages.
Upon the massive shoulders and neck of the great thag clung a tiger of such huge proportions that Tarzan could scarce credit the testimony of his own eyes. Great saber-like tusks, projecting from the upper jaw, were buried deep in the neck of the bull, which, instead of trying to escape, had stopped in its tracks and was endeavoring to dislodge the great beast of prey, swinging its huge horns backward in an attempt to rake the living death from its shoulders, or again shaking its whole body violently for the same purpose and all the while bellowing in pain and rage.
Gradually the saber-tooth changed its position until it had attained a hold suited to its purpose. Then with lightning-like swiftness it swung back a great forearm and delivered a single, terrific blow on the side of the thag’s head—a titanic blow that crushed that mighty skull and dropped the huge bull dead in its tracks. And then the carnivore settled down to feast upon its kill.
During the battle the saber-tooth had not noticed the ape-man; nor was it until after he had commenced to feed upon the thag that his eye was attracted by the revolving body swinging above the trail a few yards away. Instantly the beast stopped feeding; his head lowered and flattened, his upper lip turned back in a hideous snarl. He watched the ape-man. Low, menacing growls rumbled from his cavernous throat; his long, sinuous tail lashed angrily as slowly he arose from the body of his kill and advanced toward Tarzan of the Apes.
