which she was being borne away. Tarzan swung his rifle to his shoulder and at the same instant a riderless Gorobor struck him in the back and sent him sprawling upon the ground. By the time he had regained his feet, Jana and her captor were out of sight, hidden by the boles of intervening trees.
Milling near the Waziri were a number of terrified, riderless Gorobors. It was from this number that the fellow had broken who had knocked Tarzan down. The beasts seemed to be lost without the guidance of their masters, but when they saw one of their number start in pursuit of the Horibs who had ridden away, the others followed and in their mad rush these savage beasts constituted as great a menace as the Horibs themselves.
Muviro and his warriors leaped nimbly behind the boles of large trees to escape them, but to the mind of the ape-man they carried a new hope, offering as they did the only means whereby he might overtake the Horib who was bearing away The Red Flower of Zoram, and then, to the horror and astonishment of the Waziri, Tarzan leaped to the back of one of the great lizards as it scuttled abreast of him. Locking his toes beneath its elbows, as he had seen the Horibs do, he was carried swiftly in the mad rush of the creature to overtake its fellows and its masters. No need to urge it on, if he had known what means to employ to do so, for probably still terrified and excited by the battle it darted with incredible swiftness among the boles of the gray trees, outstripping its fellows and leaving them behind.
Presently, just ahead of him, Tarzan saw the Horib who was bearing Jana away and he saw, too, that he would soon overtake him, but so swiftly was his own mount running that it seemed quite likely that he would be carried past Jana without being able to accomplish anything toward her rescue, and with this thought came the realization that he must stop the Horib's mount.
There was just an instant in which to decide and act, but in that instant he raised his rifle and fired. Perhaps it was a wonderful bit of marksmanship, or perhaps it was just luck, but the bullet struck the Gorobor in the spine and a moment later its hind legs collapsed and it rolled over on its side, pitching Jana and the Horib heavily to the ground. Simultaneously Tarzan's mount swept by and the ape-man, risking a bad fall, slipped from its back to go tumbling head over heels against the carcass of the Horib's mount.
Leaping to his feet, he faced the lizard-man and as he did so the ground gave way beneath him and he dropped suddenly into a hole, almost to his armpits. As he was struggling to extricate himself something seized him by the ankles and dragged him downward—cold fingers that clung relentlessly to him dragging him into a dark, subterranean hole.
XVI ESCAPE
THE O-220 cruised slowly above the Gyor Cors, watchful eyes scanning the ground below, but the only living things they saw were huge dinosaurs. Disturbed by the motors of the dirigible, the great beasts trotted angrily about in circles and occasionally an individual, sighting the ship above him, would gallop after it, bellowing angrily, or again one might charge the elliptical shadow that moved along the ground directly beneath the O-220.
'Sweet tempered little fellows,' remarked Lieutenant Hines, who had been watching them from a messroom port.
'Jes' which am dem bad dreams, Lieutenant?' asked Robert Jones.
'Triceratops,' replied the officer.
'Ah'll try most anything once, suh, but not dem babies,' replied Robert.
Unknown to the bewildered navigating officer, the. ship was taking a southeasterly course. Far away, on its port side, loomed a range of mountains, hazily visible in the upcurving distance, and now a river cut the plain—a river that came down from the distant mountains—and this they followed, knowing that men lost in a strange country are prone to follow the course of a river, if they are so fortunate as to find one.
They had followed the river for some distance when Lieutenant Dorf telephoned down from the observation cabin. 'There is a considerable body of water ahead, sir,' he reported to Captain Zuppner. 'From its appearance I should say that we might be approaching the shore of a large ocean.'
'All eyes were now strained ahead and presently a large body of water became visible to all on board. The ship cruised slowly up and down the coast for a short distance, and as it had been some time since they had had fresh water or fresh meat, Zuppner decided to land and make camp, selecting a spot just north of the river they had been following, where it emptied into the, sea. And as the great ship settled gently to rest upon a rolling, grassy meadow, Robert Jones made an entry in his little black diary.
'Arrived here at noon.'
While the great ship settled down beside the shore of the silent Pellucidarian sea, Jason Gridley and his companions, hundreds of miles to the west, pushed their tunnel upward toward the surface of the ground. Jason was in front, laboriously pushing the earth backward a few handfuls at a time to those behind him. They were working frantically now because the length of the tunnel already was so great that it was with difficulty that they could return to the cavern in time to forestall discovery when they heard Horibs approaching.
As Jason scraped away at the earth above him, there broke suddenly upon his ears what sounded like the muffled reverberation of rifle shots. He could not believe that they were such, and yet what else could they be? For so long had he been separated from his fellows that it seemed impossible that any freak of circumstance had brought them to this gloomy corner of Pellucidar, and though hope ran high yet he cast this idea from his mind, substituting for it a more natural conclusion—that the shots had come from the arquebuses of Korsars, who had come up from the ship that Lajo had told him was anchored somewhere below in the Rela Am. Doubtless the captain had sent an expedition in search of the missing members of his crew, but even the prospects of falling again into the hands of the fierce Korsars appeared a heavenly one by comparison to the fate with which they were confronted.
Now Jason redoubled his efforts, working frantically to drive his narrow shaft upward toward the surface. The sound of the shots, which had lasted but a few minutes, had ceased, to be followed by the rapidly approaching thunder of many feet, as though heavy animals were racing in his direction. He heard them passing almost directly overhead and they seemed so close that he was positive he must be near the surface of the ground. Another shot sounded almost directly above him; he heard the thud of a heavy body and the earth about him shook to the impact of its fall. Jason's excitement had arisen to the highest pitch when suddenly the earth gave way above him and something dropped into the shaft upon his head.
His mind long imbued with the fear that their plan for escape would be discovered by the Horibs, Jason reacted instinctively to the urge of self-preservation, the best chance for the accomplishment of which seemed to be to drag the discoverer of their secret out of sight as quickly as possible, and with this end in view he backed quickly into the tunnel, dragging the interloper with him, and to a certain point this was not difficult, but it so happened that Tarzan had clung to his rifle. The rifle chanced to strike the ground in a horizontal position, as the ape-man was dragged into the tunnel, and the muzzle and butt lodged upon opposite sides of the opening, thus forming a rigid bar across the mouth of the aperture, to which the ape-man clung as Jason dragged frantically upon his ankles, and then slowly the steel thews of the Jungle Lord tensed and as he drew himself upward, he drew Jason Gridley with him. Strain and struggle as he would, the American could not overcome the steady pull of those giant thews. Slowly, irresistibly, he was dragged into the shaft and upward toward the surface of the ground.
By this time, of course, he knew that the creature to which he clung was no Horib, for his fingers were closed upon the smooth skin of a human being, and not upon the scaly hide of a lizard-man, but yet he felt that he must not let the fellow escape.
The Horib, who had been expecting Tarzan's attack, had seen him disappear mysteriously into the ground; nor did he wait to investigate the miracle, but seizing Jana by the wrist he hurried after his fellows, dragging the struggling girl with him.
The two were just disappearing among the boles of the trees down a gloomy aisle of the somber forest when Tarzan, emerging from the shaft, caught a single fleeting glimpse of them. It was almost the growl of an enraged beast that escaped his lips as he realized that this last calamity might have definitely precluded the possibility of effecting the girl's rescue. Chafing at the restraint of the clutching fingers clinging desperately to his ankles, the ape-man kicked violently in an effort to dislodge them and with such good effect that he sent Jason tumbling back into his tunnel, while he leaped to the solid ground and freedom to spring into pursuit of the Horib and The Red Flower of Zoram.
