The flight engineer glanced at the irritated scientist curiously and sympathetically: "If you don't know, I couldn't tell you what it's all about myself, I'm sure," he said slowly. "Cephalon—Cephalon is a place alright, but it doesn't show on the map. Sort of a Shangri-la, if you know what I mean."

This cryptic statement failed to have a calming effect on Lee. "Nonsense," he frowned. "If it is an inhabited place it must be on the map and if it isn't on the map the place doesn't exist."

"Look here," the flight engineer pointed through the window to the horizon ahead. "What do you think this is, doctor, a mirage?"

Lee stared at the apparition which swiftly materialized out of the ground haze at the plane's supersonic speed. "It does look like a mirage," he said judiciously. "Is that Cephalon?"

The engineer nodded. "Prettiest little town in the U. S. for my money. Ideal airport, too. Rather unusual though—I mean the architecture. Take a good look while we're circling around for the come-in signal."

Pretty and unusual were hardly the words for it, Lee thought, as he gazed in admiration. Below, Cephalon spread like a visionary's dream of a far-away future blended with a far-away past. Along wide, palm shaded avenues the flat-roofed terraced houses fanned out into the desert. Style elements of ancient Peru and Mexico were blended together with the latest advances of technology, such as the rectangular sheets of water which covered and cooled the roofs. The business center, dotted with helicopter landing fields on top of the pyramidal buildings, was reminiscent of the classic Babylon and Nineveh. At the center of the man-made oasis a huge fortress-like structure sprawled and towered like a seven-pointed star. Even so, for all its impressiveness of masonry, the lush green of its parks, the bursts of color from its hanging gardens, made Cephalon resemble one enormous flower bed.

Overawed and mystified the lone passenger from Down-Under took in the scene while the big plane circled with diminished speed. "It's beautiful," he murmered. "It's a dream." And louder then: "Pardon me if I find it hard to trust my senses. I've been away from home for more than ten years, to be sure. But then, even in the Australian bush I've received some periodicals and scientific journals from the U.S.A. Surely if a city like this has been built during my absence there should have been mention of the fact. And surely a city like this must show on some map. I don't understand. The longer I look the less I understand...."

The flight engineer shrugged. "It's a new city, maybe that's why it doesn't show."

Lee nodded. "In that case you must know the meaning of all this. Why did they build this city in the middle of the desert? What purpose does it serve? Why am I here? Why are we circling for so long? There don't seem to be any other planes up in the air."

"We cannot come in until our cargo has been examined and okayed," the engineer said.
