Whereupon they drew up three of those curious chairs of some heavy wood carved with the hideous figures of this strange people’s ancient gods, and Professor Stevens began.
Their sunken empire, as he had surmised, had indeed been the great island of Antillia and a colony of Atlantis. A series of earthquakes and tidal waves such as engulfed their homeland ages before had sent it down, and the estimated archaeological date of the final submergence – namely, 200 B. C. – was approximately correct.
But long before this ultimate catastrophe, the bulk of the disheartened population had migrated to Central and South America, founding the Mayan and Incan dynasties. Many of the faithful had stayed on, however, among them most of the Cabiri or high priests, who either were loath to leave their temples or had been ordered by their gods to remain.
At any rate, they had remained, and as the great island sank lower and lower, they had fortified themselves against the disaster in their pyramids, which by then alone remained above the surface.
These, too, had gradually disappeared beneath the angry waters, however, and with them had disappeared the steadfast priests and their faithful followers, sealing their living tombs into air-tight bell-jars that retained the atmosphere.
This they had supplemented at first by drawing it down from above, but as time went by they found other means of getting air; extracting it from the sea water under pressure, by utilizing their subterranean volcanoes, in whose seething cauldrons the gods had placed their salvation; and it was this process that now provided them with the atmosphere which had so amazed their captives.
But naturally, lack of sunshine had produced serious degeneration in their race, and that accounted for their diminutive forms and pale bodies. Still, they had been able to survive with a degree of happiness until some ten or a dozen years ago, when a strange enemy had come down in a great metal fish, like that of these new strangers, and with a handful of men had conquered their country.
This marauder was after their gold and had looted their temples ruthlessly, carrying away its treasures, for which they hated him with a fury that only violation of their most sacred deities could arouse. Long ago they would have destroyed him, but for the fact that he possessed terrible weapons which were impossible to combat. But they were in smouldering rebellion and waited only the support of their gods, when they would fall on this oppressor and hurl him off.
That, though it left many things unexplained, was all the professor had been able to gather from his conversation with the leader of their captors. He ended, admitting regretfully that he was still in ignorance of what fate had befallen Captain Petersen and the crew of the Nereid.
“Perhaps this fellow in the other submarine has got them,” suggested Larry.
“But why weren’t we taken to him too?” asked Diane. “What do you suppose they want with us, anyway, daddy?”
“That, my dear, as I told you before,” replied her father, “I am not disposed to conjecture. Time will reveal it. Meanwhile, we can only wait.”
As before, there was a note of anxiety in his voice not lost on either of them. And as for Larry, though he knew but little of those old religions, he knew enough to realize that their altars often ran with the blood of their captives, and he shuddered.
With these grim thoughts between them, the trio fell silent.
A silence that was interrupted presently by the arrival of a native bearing a tray heaped with strange food.
Bowing, he placed it before them and departed.
Upon examination, the meal proved to consist mainly of some curious kind of steamed fish, not unpalatable but rather rank and tough. There were several varieties of fungus, too, more or less resembling mushrooms and doubtless grown in some sunless garden of the pyramid.
These articles, together with a pitcher of good water that had obviously been distilled from the sea, comprised their meal, and though it was far from appetizing, they ate it.
But none of the three slept that night, though Diane dozed off for a few minutes once or twice, for their apprehension of what the dawn might hold made it impossible, to say nothing of the closeness of the air in that windowless subterranean room.
Slowly, wearily, the hours dragged by.
At length the native who had brought their food came again. This time he spoke.
“He says we are now to be taken before the high priests,” Professor Stevens translated for them.
Almost with relief, though their faces were grave, they stepped out into the corridor, where an escort waited.
Five minutes later, after proceeding along an inclined gallery that wound ever upward, they were ushered into a vast vaulted chamber lit with a thousand phosphorescent lamps and gleaming with idols of gold and silver, jewels flashing from their eyes.
High in the dome hung a great golden disc, representing the sun. At the far end, above a marble altar, coiled a dragon with tusks of ivory and scales of jade, its eyes two lustrous pearls.
And all about the room thronged priests in fantastic head-dress and long white robes, woven through elaborately with threads of yellow and green.
At the appearance of the captives, a murmur like a chant rose in the still air. Someone touched a brand to the altar and there was a flash of flame followed by a thin column of smoke that spiraled slowly upward.
Now one of the priests stepped out – the supreme one among them, to judge from the magnificence of his robe – and addressed the trio, speaking slowly, rhythmically.
As his strange, sonorous discourse continued, Professor Stevens grew visibly perturbed. His beard twitched and he shifted uneasily on his feet.
Finally the discourse ceased and the professor replied to it, briefly. Then he turned grave eyes on Larry and Diane.
“What is it?” asked the latter, nervously. “What did the priest say, daddy?”
Her father considered, before replying.
“Naturally, I did not gather everything,” was his slow reply, “but I gathered sufficient to understand what is afoot. First, however, let me explain that the dragon you see over there represents their deity Tlaloc, god of the sea. In more happy circumstances, it would be interesting to note that the name is identified with the Mayan god of the same element.”
He paused, as though loath to go on, then continued:
“At any rate, the Antillians have worshipped Tlaloc principally, since their sun god failed them. They believe he dragged down their empire in his mighty coils, through anger with them, and will raise it up again if appeased. Therefore they propose today to – ”
“Daddy!” cried Diane, shrinking back in horror, while a chill went up Larry’s spine. “You mean – mean that – ”
“I mean, my poor child, that we are about to be sacrificed to the dragon god of the Antillians.”
The words were no more than uttered, when with a weird chant the Cabiri closed in on their victims and led them with solemn ceremonial toward the altar.
In vain did Professor Stevens protest. Their decision had been made and was irrevocable. Tlaloc must be appeased. Lo, even now he roared for the offering!
They pointed to the dragon, from whose nostrils suddenly issued hissing spurts of flame.
Larry fumed in disgust at the cheap hocus-pocus of it – but the next moment a more violent emotion swept over him as he saw Diane seized and borne swiftly to that loathsome shrine.
But even as he lunged forward, the professor reached his daughter’s side. Throwing himself in front of her, he begged them to spare her, to sacrifice him instead.
The answer of the priests was a blow that knocked the graybeard senseless, and lifting Diane up, half-swooning, they flung her upon the altar.
“Mr. Hunter! Larry!” came her despairing cry.
She struggled
