How marvelous, how utterly incredible, to find human beings here! How many were there? Where had they come from? How had they salvaged us from Penguin Deep? I gave it up, striding along with my towering guards like a man walking in his sleep. At length the low passageway ended, and I exclaimed aloud at what I saw. I was looking down a long avenue of buildings, all three stories in height. There were large door and window apertures, but no doors nor window panes. In front of each house was a small square with--wonder of wonders!--a lawn of whitish yellow vegetation that resembled grass. In some of the lawns were set artistic fountains of carved rock. I might have been looking down any prosperous earthly subdivision, save for the fact that the roofs of the houses were the earth itself, which the building walls, in addition to functioning as partitions, served to support. Also earthly subdivisions aren't usually illuminated with rosy light that comes softly roaring from jets set in the walls. * * * * * We were walking toward a more brightly lighted area that showed ahead of us. On the way we passed intersections where other, similar streets branched geometrically away to right and left. These were smaller than the one we were on, indicating that ours was Main Street in this bizarre submarine city. Faces appeared at door and window openings to peer at me as we passed. And even in that jumbled moment I had time to realize that these folk could restrain curiosity better than we can atop the earth. There was no hub-bub, no running out to tag after the queerly dressed foreigner and shout humorous remarks at him. We approached the bright spot I had noticed from afar. It was an open square, about a city block in area, in the center of which was a royal looking building covered with blazing fragments of crystal and so brilliantly resplendent with light that it seemed to glow at the heart of a pink fire. I was led toward this and in through a wide doorway. As courteously as though I were a visiting king, I was conducted up a great staircase, down a corridor set with more of the sparkling crystals and into a huge, low room. There my escort bowed and left me. * * * * * Still feeling that I could not possibly be awake and seeing actual things, I glanced around. In a corner was another of the mattresslike couches made of the thick, soft hide that seemed to be the principal fabric of the place. A few feet away was a table set with dishes of food in barbaric profusion. None of the viands looked familiar but all appealed to the appetite. The floor was strewn with soft skins, and comfortable, carved benches were scattered about.
