Releasing one end of the rope, he let that fall to its full length, and when he saw where the lower end touched the granite wall he was satisfied that he could descend at least that far, and below that another twenty-five feet. But it was difficult to measure distances below that point and from there on he must leave everything to chance.
Drawing the rope up again he looped the center of it about a projecting bit of granite, permitting the ends to fall over the edge of the cliff. Then he seized both strands of the rope tightly in one hand and lowered himself over the edge. Twenty feet below was a projection that gave him precarious foothold and a little crevice into which he could insert the fingers of his left hand. Almost directly before his face was the top of a buttress-like projection and below him he knew that there were many more similar to it. It was upon these that he had based his slender hope of success.
Gingerly he pulled upon one strand of the rope with his right hand. So slender was his footing upon the rocky escarpment that he did not dare draw the rope more than a few inches at a time lest the motion throw him off his balance. Little by little he drew it in until the upper end passed around the projection over which the rope had been looped at the summit and fell upon him. And as it descended he held his breath for fear that even this slight weight might topple him to the jagged rocks below.
And now came the slow process of drawing the rope unaided through one hand, fingering it slowly an inch at a time until the center was in his grasp. This he looped over the top of the projection in front of him, seating it as securely as he could, and then he grasped both strands once more in his right hand and was ready to descend another twenty-five feet.
This stage of the descent was the most appalling of all, since the rope was barely seated upon a shelving protuberance from which he was aware it might slip at any instant. And so it was with a sense of unspeakable relief that he again found foothold near the end of the frail strands that were supporting him.
At this point the surface of the spire became much rougher. It was broken by fissures and horizontal cracks that had not been visible from above, with the result that compared with the first fifty feet the descent from here to the base was a miracle of ease, and it was not long before Tarzan stood again squarely upon his two feet and level ground. And now for the first time he had an opportunity to take stock of his injuries.
His legs were scratched and cut by the teeth and talons of the young thipdars, but these wounds were as nothing to those left by the talons of the adult reptile upon his back and shoulders. He could feel the deep wounds, but he could not see them; nor the clotted blood that had dried upon his brown skin.
The wounds pained and his muscles were stiff and sore, but his only fear lay in the possibility of blood poisoning and that did not greatly worry the ape-man, who had been repeatedly torn and mauled by carnivores since childhood.
A brief survey of his position showed him that it would be practically impossible for him to recross the stupendous gorge that yawned between him and the point at which he had been so ruthlessly torn from his companions. And with that discovery came the realization that there was little or no likelihood that the people toward which Tar-gash had been attempting to guide him could be members of the O-220 expedition. Therefore it seemed useless to attempt the seemingly impossible feat of finding Thoar and Tar-gash again among this maze of stupendous peaks, gorges and ravines. And so he determined merely to seek a way out of the mountains and back to the forests and plains that held a greater allure for him than did the rough and craggy contours of inhospitable hills. And to the accomplishment of this end he decided to follow the line of least resistance, seeking always the easiest avenues of descent.
Below him, in various directions, he could see the timber line and toward this he hastened to make his way. As he descended the way became easier, though on several occasions he was again compelled to resort to his rope to lower himself from one level to another. Then the steep crags gave place to leveler land upon the shoulders of the mighty range and here, where earth could find lodgment, vegetation commenced. Grasses and shrubs, at first, then stunted trees and finally what was almost a forest, and here he came upon a trail.
It was a trail that offered infinite variety. For a while it wound through a forest and then climbed to a ledge of rock that projected from the face of a cliff and overhung a stupendous canyon.
He could not see the trail far ahead for it was continually rounding the shoulders of jutting crags.
As he moved along it, sure-footed, silent, alert, Tarzan of the Apes became aware that somewhere ahead of him other feet were treading probably the same trail.
What wind there was was eddying up from the canyon below and carrying the scent spoor of the creature ahead of him as well as his own up toward the mountain top, so that it was unlikely that either might apprehend the presence of the other by scent; but there was something in the sound of the footsteps that even at a distance assured Tarzan that they were not made by man, and it was evident too that they were going in the same direction as he for they were not growing rapidly more distinct, but very gradually as though he was slowly overhauling the author of them.
The trail was narrow and only occasionally, where it crossed some ravine or shallow gulley, was there a place where one might either descend or ascend from it.
To meet a savage beast upon it, therefore, might prove, to say the least, embarrassing but Tarzan had elected to go this way and he was not in the habit of turning back whatever obstacles in the form of man or beast might bar his way. And, too, he had the advantage over the creature ahead of him whatever it might be, since he was coming upon it from behind and was quite sure that it had no knowledge of his presence, for Tarzan well knew that no creature could move with greater silence than he, when he elected to do so, and now he passed along that trail as noiselessly as the shadow of a shadow.
Curiosity caused him to increase his speed that he might learn the nature of the thing ahead, and as he did so and the sound of its footsteps increased in volume, he knew that he was stalking some heavy, four-footed beast with padded feet—that much he could tell, but beyond that he had no idea of the identity of the creature; nor did the winding trail at any time reveal it to his view. Thus the silent stalker pursued his way until he knew that he was but a short distance behind his quarry when there suddenly broke upon his ears the horrid snarling and growling of an enraged beast just ahead of him.
There was something in the tone of that awful voice that increased the ape-man's curiosity. He guessed from the volume of the sound that it must come from the throat of a tremendous beast, for the very hills seemed to shake to the thunder of its roars.
Guessing that it was attacking or was about to attack some other creature, and spurred, perhaps, entirely by curiosity, Tarzan hastened forward at a brisk trot, and as he rounded the shoulder of a buttressed crag his eyes took in a scene that galvanized him into action.
A hundred feet ahead the trail ended at the mouth of a great cave, and in the entrance to the cave stood a boy—a lithe, handsome youth of ten or twelve—while between the boy and Tarzan a huge cave bear was advancing angrily upon the former.
The boy saw Tarzan and at the first glance his eyes lighted with hope, but an instant later, evidently recognizing that the newcomer was not of his own tribe, the expression of hopelessness that had been there before returned to his face, but he stood his ground bravely, his spear and his crude stone knife ready.
