"The greatest tower of all," the Son explained. "Hundreds of feet it soared above the earth, yet when the rockets came, it crashed as quickly as the least of them. They say that some of those who dwelt here managed to escape, being shielded from atomic fire by those whose bodies lay above them, and so they fled across the river, living for a while upon the surface above where we have built our subterranean city. But most of them died of diseases that some of the rockets brought. A few at last went north, toward what was then called Canada—"
"I know," O'Hara said. "I've read of it."
"And more died there. Only the strongest then were able to escape toward the west, perhaps into the mountains where they say a strange new race now dwells, huge red-haired creatures, as large as yourself, with short arms and stiff spines, unprepossessing creatures and enemies of the Father."
"Unprepossessing?"
"Yes. But do not take offense. Since you have come from Washington we do not mind you. I have heard it said," he whispered, "that even the Father himself—is not like us. Nor should he be, of course," the Son said hastily, and resumed his speech: "There were in this ancient city some ten or more millions of inhabitants before the Third World War, but they were situated very stupidly, grouped together densely, and we have avoided that mistake in rebuilding our new subterranean New York. Also as an object lesson of how foolishly our race once planned, the Monument was built—a replica of the ancient city as it was before its destruction. We go there now."
For four days O'Hara wandered through the empty Monument.
The fifth day, he stood before the great screen in the Guild of the subterranean city across the river and listened to the Father's voice.
"Have you seen it, O'Hara?"
"I have been there, Father."
"Is there more you wish to see?"
