The hairless men looked at one another. "This is Spiro's work," said one of them, still in English; and another said, "Yes, Spiro has done this." Miles and Ward were recovering somewhat from their initial astonishment. "What place is this?" asked the former. "This is Apex--or, rather, the Palace of the Heads in Apex." The Palace of the Heads! The two Americans tried to control their bewilderment. "Pardon us if we don't understand. Everything is so strange. First the submarine was wrecked. Then we entered the crystal room and the tunnel vanished. We can't understand how this place can be at the bottom of the Atlantic." "It isn't at the bottom of the Atlantic." "Not at the bottom? Then where?" "It isn't," said the voice slowly, "in your world at all." The import of what was said did not at first penetrate the minds of the Americans. "Not in our world?" they echoed stupidly. "Come," said the crippled man smiling inscrutably, "you are tired and hungry. Later I shall explain more." His strangely colored eyes bored into their own. "Sleep," said his voice softly, imperatively; and though they fought against the command with all the strength of their wills, heaviness weighted down their eyelids and they slept. * * * * * From dreamless sleep they awakened to find that fatigue had miraculously vanished, that their wounds were healed and their bodies and clothes were free of slime and filth. All but one of the crippled men--for so in their own minds they termed the odd individuals--had gone away. That one was the man who had first addressed them. "Do not be alarmed," he said. "In our own fashion we have given you food and rest and attended to your comfort." Ward smiled, though a trifle uncertainly. "We are not easily frightened," he replied. "So! That is good. But now listen: my name is Zoro and I am Chief of the Heads of Apex. Ages ago we Heads lived on a continent of your Earth now known to scholars as Atlantis. When Atlantis sank below the waves--in your sacred book that tragedy is known as the Flood--all but a scattered few of its people perished. I and my companions were among the survivors." The Americans stared at him unbelievingly. "But that was a hundred thousand years ago!" exclaimed Ward. "Three hundred thousand," corrected Zoro. They stared at him dumbly.
