The women were uniformly attired in white, clinging garments of translucent material that half revealed, half concealed their forms, and Ted was struck by this contrast to earthly customs where women dress brightly and men usually wear somber colors. The very small children romped about quite naked. Those a little older wore breech clouts, and the larger imitated their elders according to their sexes. Having crossed this room, Maza and Ted entered a lift which quickly whisked them to the place near the top of the tower which he had previously noticed, and through which the four cables were stretched. Suspended on overhead wheels from one of these cables was a bullet-shaped car of white metal with transparent panels in the sides and a sliding door near the center, which had apparently been held awaiting their coming. An attendant closed the door after them as they stepped in and sank into luxuriously cushioned seats. Then the vehicle started smoothly, accelerating rapidly until Ted computed that they were going at least four hundred miles an hour. As hour after hour slipped by and their speed continued unabated, Ted wondered at the great length of the valley. He consulted his wrist compass and noticed that they were traveling toward the southeast. The valley appeared quite uniform in width, and although there were a few wooded areas was, for the most part, apparently under cultivation. Most of the farms were irrigated by small ditches which branched out from a broad canal that extended down the center of the valley, and was fed from time to time, by streams which flowed through tunnels in the rocky walls on either side. Men and women were at work in the fields, some using farm machinery of unknown motive power, some assisted by dragon-like draft animals, and others using only hand tools. Noticing that Ted was apparently trying to compute the distance and direction they had traveled, his companion took a rolled parchment from a pocket in the wall. It proved to be a map of the moon. She spread it out before them and pointed to the longest known lunar ray—the one which extends from the crater, Tycho, near the bottom of the southeast quadrant of the moon, curves across the southwest and northwest quadrants, and ends near the north pole in the _Mare Frigoris_. With the pink tip of her dainty forefinger she indicated their start at the crater Hipparchus, their underground trip to the glassed over crack or valley in the moon’s surface which terrestrial astronomers had always referred to as “one of the rays of Tycho,” and the distance they had traveled since they entered the cable railway. She then pointed to Tycho and said: “Ultu.” Ted understood from this that Tycho or “Ultu” was their destination, and was probably a subterranean lunar city. As Ultu was the center of the most extensive ray system on the moon, Ted assumed that it was probably the capital of one of the most populous nations.
