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 gra.s.s. 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 part.i.tions, 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 pa.s.sed 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 pa.s.sed.

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 princ.i.p.al 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 appet.i.te. The floor was strewn with soft skins, and comfortable, carved benches were scattered about.

I walked to the window and looked out. Underneath was a plot of the cream colored gra.s.s through which ran a tiny stream. This widened at intervals into clear pools beside which were set stone benches. A hundred yards away was the edge of the square, where the regular, three storied houses began.

While I was staring at this unearthly vista, still unable to think with any coherence. I heard my name called. I turned to face Stanley and the Professor.

Both were pale in the rose light, and Stanley limped with the pain of his bruised leg: but both had recovered from their partial suffocation as completely as had I.

"We thought perhaps you'd decided to swim back up to the _Rosa_ and leave us to our fates," said Stanley after we had stopped pumping each other's arms and had seated ourselves.

"And I thought--well, I didn't think much of anything," I replied. "I was too busy straining my eyesight over the wonders of this city. Did you ever see anything like it?"

"We haven't seen it at all, save for a view from the windows," said Stanley. "All we know of the place is that a while ago we woke up in a room like this, only much smaller and less lavish. I wonder why you rate this distinction?"

I described the streets as I had seen them. (It is impossible for me to think of them as anything but streets; it would seem as though the rock roof over all would give the appearance of a series of tunnels; but I had always the impression of airiness and openness.)

"Light and heat are furnished by natural gas," said the Professor when I remarked on the perfection of these two necessities. "That's what makes the low roaring noise--the thousands of burning jets. But the presence of gas here isn't as unusual as the presence of air. Where does that come from? Through wandering underground mazes, from some cave mouth in the Fiji Islands to the north? That would indicate that all the earth around here is honeycombed like a gigantic section of sponge. I wonder--"

"Have you any idea how we were rescued?" I interrupted, a little impatient of his abstract scientific ponderings.

"We have," said Stanley. "A woman told us. We woke up to find her nursing us--gorgeous looking thing--finest woman I've ever seen, and I've seen a good many--"

"She didn't exactly 'tell' us," remarked the Professor with his thin smile. Women were only interesting to him as biological studies. "She drew a diagram that explained it.

"That tunnel, Martin, was like the outer diving chamber of a submarine.

We were hauled in on a big windla.s.s--driven by gas turbines, I think.

Once we were inside, a twenty-yard, counterbalanced wall of rock was lowered across the entrance. Then the water was drained out through a well, and into a subterranean body of water that extends under the entire city. And here we are."

We fell silent. Here we were. But what was going to happen to us among these friendly-seeming people; and how--if ever--we were going to get back to the earth's surface, were questions we could not even try to answer.

We ate of the appetizing food laid out on the long table. Shortly afterward we heard steps in the corridor outside the room.

A woman entered. She was ravishingly beautiful, tall, slender but symmetrically rounded. A soft leather robe slanted upward across her breast to a single shoulder fastening and ended just above her knees in a skirt arrangement. Around her head was a regal circlet of silvery gray metal with a flashing bit of crystal set in the center above her broad, low forehead.

She smiled at Stanley who looked dazzled and smiled eagerly back.

She pointed toward the door, signifying that we were to go with her. We did so; and were led down the great staircase and to a huge room that took up half the ground floor of the building. And here we met the n.o.bility of the little kingdom--the upper cla.s.s that governed the immaculate little city.

They were standing along the walls, leaving a lane down the center of the room--tall, finely modelled men and women dressed in the single garments of soft leather. There were people there with gray hair and wisdom wrinkled faces; but all were alike in being erect of body, firm of bearing and in splendid health.

They stopped talking as we entered the big room. Our gaze strayed ahead down the lane toward the further wall.

Here was a raised dais. On it was a gleaming crystal encrusted throne.

And occupying it was the most queenly, exquisitely beautiful woman I had ever dreamed about.

Woman? She was just a girl in years in spite of her grave and royal air.

Her eyes were deep violet. Her hair was black as ebony and gleaming with sudden glints of light. Her skin--

But she cannot be described. Only a great painter could give a hint of her glory. Too, I might truthfully be described as prejudiced about her perfections.

The Queen, for patently she was that, bowed graciously at us. It seemed to me--though I told myself that I was an imaginative fool--that her eyes rested longest on me, and had in them an expression not granted to the Professor or Stanley.

She spoke to us a melodious sentence or two, and waved her beautiful hand in which was a short ivory wand, evidently a scepter.

"She's probably giving us the keys to the city," whispered Stanley. He edged nearer the fair one who had conducted us. "I sincerely hope there's room here for us."

The open lane closed in on us. Men and women crowded about us speaking to us and smiling ruefully as they realized we could not understand. I noticed that, for some curious reason, they seemed fascinated by the color of my hair. Red-haired men were evidently scarce there.

At length the beauty who had so captured Stanley's fancy, and who seemed to have been appointed a sort of mentor for us, suggested in sign language that we might want to return to our quarters.

It was a welcome suggestion. We were done in by the experiences and emotions that had gripped us since leaving the _Rosa_ such an incredibly few hours ago.

We went back to the second floor. I to my luxurious big apartment and Stanley and the Professor to their smaller but equally comfortable rooms.

A pleasant period slid by, every waking hour of which was filled with new experiences.

The city's name, we found, was Zyobor. It was a perfect little community. There were artisans and thinkers, artists and laborers--all alike in being physically perfect beyond belief and cultured as no race on top the ground is cultured.

As we began to learn the language, more exact details of the practical methods of existence were revealed to us.

The surrounding earth furnished them with building materials, metals and unlimited gas. The sea, so near us and yet so securely walled away, gave them food. Which warrants a more detailed description.
