shoot her swift displeasure at the instigator of this sacrilegious interruption.
There was a sudden commotion in the direction of the disputants, and Tarzan rolled his head in their direction in time to see the burly brute of a priest leap upon the woman opposite him, dashing out her brains with a single blow of his heavy cudgel. Then that happened which Tarzan had witnessed a hundred times before among the wild denizens of his own savage jungle. He had seen the thing fall upon Kerchak, and Tublat, and Terkoz; upon a dozen of the other mighty bull apes of his tribe; and upon Tantor, the elephant; there was scarce any of the males of the forest that did not at times fall prey to it. The priest went mad, and with his heavy bludgeon ran amuck among his fellows.
His screams of rage were frightful as he dashed hither and thither, dealing terrific blows with his giant weapon, or sinking his yellow fangs into the flesh of some luckless victim. And during it the priestess stood with poised knife above Tarzan, her eyes fixed in horror upon the maniacal thing that was dealing out death and destruction to her votaries.
Presently the room was emptied except for the dead and dying on the floor, the victim upon the altar, the high priestess, and the madman. As the cunning eyes of the latter fell upon the woman they lighted with a new and sudden lust. Slowly he crept toward her, and now he spoke; but this time there fell upon Tarzan’s surprised ears a language he could understand; the last one that he would ever have thought of employing in attempting to converse with human beings—the low guttural barking of the tribe of great anthropoids—his own mother tongue. And the woman answered the man in the same language.
He was threatening—she attempting to reason with him, for it was quite evident that she saw that he was past her authority. The brute was quite close now—creeping with clawlike hands extended toward her around the end of the altar. Tarzan strained at the bonds which held his arms pinioned behind him. The woman did not see—she had forgotten her prey in the horror of the danger that threatened herself. As the brute leaped past Tarzan to clutch his victim, the ape-man gave one superhuman wrench at the thongs that held him. The effort sent him rolling from the altar to the stone floor on the opposite side from that on which the priestess stood; but as he sprang to his feet the thongs dropped from his freed arms, and at the same time he realized that he was alone in the inner temple—the high priestess and the mad priest had disappeared.
And then a muffled scream came from the cavernous mouth of the dark hole beyond the sacrificial altar through which the priestess had entered the temple. Without even a thought for his own safety, or the possibility for escape which this rapid series of fortuitous circumstances had thrust upon him, Tarzan of the Apes answered the call of the woman in danger. With a little bound he was at the gaping entrance to the subterranean chamber, and a moment later was running down a flight of age-old concrete steps that led he knew not where.
The faint light that filtered in from above showed him a large, low-ceiled vault from which several doorways led off into inky darkness, but there was no need to thread an unknown way, for there before him lay the objects of his search—the mad brute had the girl upon the floor, and gorilla-like fingers were clutching frantically at her throat as she struggled to escape the fury of the awful thing upon her.
As Tarzan’s heavy hand fell upon his shoulder the priest dropped his victim, and turned upon her would-be rescuer. With foam-flecked lips and bared fangs the mad sun-worshiper battled with the tenfold power of the maniac. In the blood lust of his fury the creature had undergone a sudden reversion to type, which left him a wild beast, forgetful of the dagger that projected from his belt—thinking only of nature’s weapons with which his brute prototype had battled.
But if he could use his teeth and hands to advantage, he found one even better versed in the school of savage warfare to which he had reverted, for Tarzan of the Apes closed with him, and they fell to the floor tearing and rending at one another like two bull apes; while the primitive priestess stood flattened against the wall, watching with wide, fear-fascinated eyes the growing, snapping beasts at her feet.
At last she saw the stranger close one mighty hand upon the throat of his antagonist, and as he forced the bruteman’s head far back rain blow after blow upon the upturned face. A moment later he threw the still thing from him, and, arising, shook himself like a lion. He placed a foot upon the carcass before him, and raised his head to give the victory cry of his kind, but as his eyes fell upon the opening above him leading into the temple of human sacrifice he thought better of his intended act.
The girl, who had been half paralyzed by fear as the two men fought, had just commenced to give thought to her probable fate now that, though released from the clutches of a madman, she had fallen into the hands of one whom but a moment before she had been upon the point of killing. She looked about for some means of escape. The black mouth of a diverging corridor was near at hand, but as she turned to dart into it the ape-man’s eyes fell upon her, and with a quick leap he was at her side, and a restraining hand was laid upon her arm.
“Wait!” said Tarzan of the Apes, in the language of the tribe of Kerchak.
The girl looked at him in astonishment.
“Who are you,” she whispered, “who speaks the language of the first man?”
“I am Tarzan of the Apes,” he answered in the vernacular of the anthropoids.
“What do you want of me?” she continued. “For what purpose did you save me from Tha?”
“I could not see a woman murdered?” It was a half question that answered her.
“But what do you intend to do with me now?” she continued.
“Nothing,” he replied, “but you can do something for me—you can lead me out of this place to freedom.” He made the suggestion without the slightest thought that she would accede. He felt quite sure that the sacrifice would go on from the point where it had been interrupted if the high priestess had her way, though he was equally positive that they would find Tarzan of the Apes unbound and with a long dagger in his hand a much less tractable victim than Tarzan disarmed and bound.
The girl stood looking at him for a long moment before she spoke.
“You are a very wonderful man,” she said. “You are such a man as I have seen in my daydreams ever since I was a little girl. You are such a man as I imagine the forbears of my people must have been—the great race of people who built this mighty city in the heart of a savage world that they might wrest from the bowels of the earth the fabulous wealth for which they had sacrificed their far-distant civilization.
“I cannot understand why you came to my rescue in the first place, and now I cannot understand why, having me within your power, you do not wish to be revenged upon me for having sentenced you to death—for having almost put you to death with my own hand.”
“I presume,” replied the ape-man, “that you but followed the teachings of your religion. I cannot blame you for that, no matter what I may think of your creed. But who are you—what people have I fallen among?”
“I am La, high priestess of the Temple of the Sun, in the city of Opar. We are descendants of a people who came to this savage world more than ten thousand years ago in search of gold. Their cities stretched from a great sea under the rising sun to a great sea into which the sun descends at night to cool his flaming brow. They were very rich and very powerful, but they lived only a few months of the year in their magnificent palaces here; the rest of the time they spent in their native land, far, far to the north.
“Many ships went back and forth between this new world and the old. During the rainy season there were but few of the inhabitants remained here, only those who superintended the working of the mines by the black
