of the arm that swung the club. With equal celerity he shot his right leg behind the shaggy brute and throwing his weight forward hurled the thing over his hip heavily to the ground, at the same time precipitating his own body upon the other's chest.
With the shock of the impact the club fell from the brute's hand and Tarzan's hold was wrenched from its throat. Instantly the two were locked in a deathlike embrace. Though the creature bit at Tarzan the latter was quickly aware that this was not a particularly formidable method of offense or defense, since its canines were scarcely more developed than his own. The thing that he had principally to guard against was the sinuous tail which sought steadily to wrap itself about his throat and against which experience had afforded him no defense.
Struggling and snarling the two rolled growling about the sward at the foot of the tree, first one on top and then the other but each more occupied at present in defending his throat from the other's choking grasp than in aggressive, offensive tactics. But presently the ape-man saw his opportunity and as they rolled about he forced the creature closer and closer to the pool, upon the banks of which the battle was progressing. At last they lay upon the very verge of the water and now it remained for Tarzan to precipitate them both beneath the surface but in such a way that he might remain on top.
At the same instant there came within range of Tarzan's vision, just behind the prostrate form of his companion, the crouching,
devil-faced figure of the striped saber-tooth hybrid, eyeing him with snarling, malevolent face.
Almost simultaneously Tarzan's shaggy antagonist discovered the menacing figure of the great cat. Immediately he ceased his bellig-erent activities against Tarzan and, jabbering and chattering to the ape-man, he tried to disengage himself from Tarzan's hold but in such a way that indicated that as far as he was concerned their battle was over. Appreciating the danger to his unconscious companion and being anxious to protect him from the saber-tooth the ape-man relinquished his hold upon his adversary and together the two rose to their feet.
Drawing his knife Tarzan moved slowly toward the body of his companion, expecting that his recent antagonist would grasp the op-
portunity for escape. To his surprise, however, the beast, after regaining its club, advanced at his side.
The great cat, flattened upon its belly, remained motionless except for twitching tail and snarling lips where it lay perhaps fifty feet beyond the body of the pithecanthropus. As Tarzan stepped over the body of the latter he saw the eyelids quiver and open, and
in his heart he felt a strange sense of relief that the creature was not dead and a realization that without his suspecting it there had
6
arisen within his savage bosom a bond of attachment for this strange new friend.
Tarzan continued to approach the saber-tooth, nor did the shaggy beast at his right lag behind. Closer and closer they came until at a distance of about twenty feet the hybrid charged. Its rush was directed toward the shaggy manlike ape who halted in his tracks with upraised bludgeon to meet the assault. Tarzan, on the contrary, leaped forward and with a celerity second not even to that of the swift-moving cat, he threw himself headlong upon him as might a Rugby tackler on an American gridiron. His right arm circled the
beast's neck in front of the right shoulder, his left behind the left foreleg, and so great was the force of the impact that the two rolled over and over several times upon the ground, the cat screaming and clawing to liberate itself that it might turn upon its attacker, the man clinging desperately to his hold.
Seemingly the attack was one of mad, senseless ferocity unguided by either reason or skill. Nothing, however, could have been farther from the truth than such an assumption since every muscle in the ape-man's giant frame obeyed the dictates of the cunning mind that long experience had trained to meet every exigency of such an encounter. The long, powerful legs, though seemingly inextricably entangled with the hind feet of the clawing cat, ever as by a miracle, escaped the raking talons and yet at just the proper instant in the midst of all the rolling and tossing they were where they should be to carry out the ape-man's plan of offense. So that on the instant that the cat believed it had won the mastery of its antagonist it was jerked suddenly upward as the ape-man rose to his feet, holding the striped back close against his body as he rose and forcing it backward until it could but claw the air helplessly.
Instantly the shaggy black rushed in with drawn knife which it buried in the beast's heart. For a few moments Tarzan retained his hold but when the body had relaxed in final dissolution he pushed it from him and the two who had formerly been locked in mortal combat stood facing each other across the body of the common foe.
Tarzan waited, ready either for peace or war. Presently two shaggy black hands were raised; the left was laid upon its own heart and the right extended until the palm touched Tarzan's breast. It was the same form of friendly salutation with which the pithecanthropus had sealed his alliance with the ape-man and Tarzan, glad of every ally he could win in this strange and savage world, quickly accepted the proffered friendship.
At the conclusion of the brief ceremony Tarzan, glancing in the direction of the hairless pithecanthropus, discovered that the latter had recovered consciousness and was sitting erect watching them intently. He now rose slowly and at the same time the shaggy black turned in his direction and addressed him in what evidently was their common language. The hairless one replied and the two approached each other slowly. Tarzan watched interestedly the outcome of their meeting. They halted a few paces apart, first one and then the other speaking rapidly but without apparent excitement, each occasionally glancing or nodding toward Tarzan, indicating that he was to some extent the subject of their conversation.
Presently they advanced again until they met, whereupon was repeated the brief ceremony of alliance which had previously marked the cessation of hostilities between Tarzan and the black. They then advanced toward the ape-man addressing him earnestly as though endeavoring to convey to him some important information. Presently, however, they gave it up as an unprofitable job and, resorting to sign language, conveyed to Tarzan that they were proceeding upon their way together and were urging him to accompany them.
As the direction they indicated was a route which Tarzan had not previously traversed he was extremely willing to accede to their
request, as he had determined thoroughly to explore this unknown land before definitely abandoning search for Lady Jane therein.
For several days their way led through the foothills parallel to the lofty range towering above. Often were they menaced by the savage denizens of this remote fastness, and occasionally Tarzan glimpsed weird forms of gigantic proportions amidst the shadows of the nights.
On the third day they came upon a large natural cave in the face of a low cliff at the foot of which tumbled one of the numerous mountain brooks that watered the plain below and fed the morasses in the lowlands at the country's edge. Here the three took up their temporary abode where Tarzan's instruction in the language of his companions progressed more rapidly than while on the march.
The cave gave evidence of having harbored other manlike forms in the past. Remnants of a crude, rock fireplace remained and the walls and ceiling were blackened with the smoke of many fires. Scratched in the soot, and sometimes deeply into the rock beneath, were strange hieroglyphics and the outlines of beasts and birds and reptiles, some of the latter of weird form suggesting the extinct creatures of Jurassic times. Some of the more recently made hieroglyphics Tarzan's companions read with interest and commented upon, and then with the points of their knives they too added to the possibly age-old record of the blackened walls.

Tarzan's curiosity was aroused, but the only explanation at which he could arrive was that he was looking upon possibly the world's most primitive hotel register. At least it gave him a further insight into the development of the strange creatures with which Fate had thrown him. Here were men with
