Cities in Flight

something else that’s worth something? Clear out, bum. You’re broke. Take it from me as a friend, clear out; I’m giving you good advice.”

He seemed to have calmed down a little, Amalfi said. “What’s wrong with germanium?”

“Nothing,” the dockman said, looking at Amalfi over his incredible nose with a mixture of compassion and vindictiveness. “It’s a good, useful metal. But it just isn’t money any more, Okie. I don’t see how you could have missed finding that out. Germanium is trash now—well, no, it’s still worth something, but only what it’s actually worth, if you get me. You have to buy it; you can’t buy other things with it.

“It’s no good here as money. It’s no good anywhere else, either. Anywhere else. The whole galaxy is broke. Dead broke.”

“And so are you.”

He wiped his eyes again. Overhead a siren groaned, softly but urgently.

Hazleton was ready, and had sighted the incoming cops.

Amalfi found it impossible to understand what happened when he closed the “spin” key. He did not hope to understand it at any time in the future, either; and it would do no good to ask the City Fathers, who would simply refuse to tell him—for the very good reason that they did not know. Whatever they had had in reserve for Standard Situation N— that ultimate situation which every Okie city must expect to face eventually, the situation wherein what is necessary to prevent total destruction is only and simply to get away fast— it was drastic and unprecedented. Or it had become so when the City Fathers had been given the chance to pool their knowledge with that of the City Fathers of the all-purpose city.

The city snapped from its graving dock on Murphy to a featureless coordinate-set in space. The movement took no time and involved no detectable display of energy. One moment the city was on Murphy; Amalfi closed the key, and Murphy had vanished, and Jake was demanding to know where in space the city was. He was told to find out.

The cops had come up on Murphy in fair order, but they had not been given the chance to fire a single shot. When Jake had managed to find Murphy again, O’Brian sent a proxy out to watch the cops, who by that time were shooting back and forth across the planet’s sky like belated actors looking for a crucial collar button.

An hour later, without the slightest preliminary activity, the all-purpose city snapped out of existence on Murphy. By the time the garagemen had recovered enough to sound another alarm, the cops were scattered in all directions, still hunting something that they had had no prior idea could turn up missing: Amalfi’s own town. By the time they managed to reform their ranks sufficiently to trace the all-purpose city, it had stopped operating, and thus had become undetectable.

It was floating now in an orbit half a million miles away from Amalfi’s city. Its screens were down again. If there had been any garage-men on it when it took off, they were dead now; the city was airless.

And the City Fathers honestly did not know how all this had been accomplished; or, rather, they no longer knew. Standard Situation N was keyed in by a sealed and self-blowing circuit. It had been set up that way long ago, to prevent incompetent or lazy city administrators from calling upon it at every minor crisis. It could never be used again.

And Amalfi knew that he had called it into use, not only for his own city, but for the other one as well, in a situation which had not really been the ultimate extreme, had not really been Situation N. He had squandered the final recourse of both cities.

He was still equally certain that neither city would ever need that circuit again.

The two cities, linked only by an invisible ultraphone tight-beam, were now floating free in the starless area three light years away from the jungle, and eight parsecs away from Murphy. The dim towers of the dead city were not visible to Amalfi, who stood alone on the belfry of City Hall; but they floated in his brain, waiting for him to tell them to come to life.

Whether or not his act of extreme desperation in the face of a not ultimately desperate situation had in actuality murdered that city was a question he could not decide. In the face of the galactic disaster, the question seemed very small.

He shelved it to consider what he had learned about his own bad check. Germanium never had had the enormous worth in real terms that it had had as a treasure metal. It did have properties which made it valuable in many techniques: the germanium lattice would part with an electron at the urging of a comparatively low amount of energy; the p-n boundary functioned as a crystal detector; and so on. The metal found its way into uncountable thousands of electronic devices—and, it was rare.

But not that rare. Like silver, platinum, and iridium before it, germanium’s treasure value had been strictly artificial—an economic convention, springing from myths, jewelers’ preferences, and the jealousy of statal monopolies. Sooner or later, some planet or cluster with a high technology—and a consequently high exchange rate—would capture enough of the metal to drive its competitors, or, more likely, its own treasury, off the germanium standard; or someone would learn to synthesize or transmute the element cheaply. It hardly mattered which had happened now.

What mattered was the result. The actual metallic germanium on board the city now had only an eighth of its former value at current rates of sale. Much worse, however, was the fact that most of the city’s funds were not metal, but paper: Oc dollars, issued against government-held metal back on Earth and a few other administrative centers. This money, since it did not represent any metallic germanium that belonged to the city, was now unredeemable—valueless.

The new standard was a drug standard. Had the city come away from He with the expected heavy surplus of anti-agathics, it would now have been a multibillionaire. Instead, it was close to being a pauper.

Amalfi wondered how the drug standard had come about. To Okies, cut off for the most part from the main stream of history, such developments frequently seemed like the brainstorms of some unknown single genius; it was hard to think of them as evolving from a set of situations when none of the situations could now be intimately known. Still, however it had arisen, the notion had its point. Drugs can be graded exactly as to value by their therapeutic effect and their availability. Drugs that could be made synthetically in quantity at low cost would be the pennies and nickels of the new coinage—and those that could not, and were rare and always in heavier demand than the supply could meet, would be the hundred-dollar units.

Further, even expensive drugs could be diluted, which would make debt payment flexible; drugs could be as amenable to laboratory test for counterfeit as metal had been; and finally, drugs became outmoded rapidly enough to make for a high-velocity currency which could not be hoarded or cornered, even by the most predatory measures.

It was a good standard. Since it would be impossible to carry on real transactions in terms of fractions of a cubic centimeter of some chemical, just as it had been impractical to carry a ton and a half of germanium about in order to pay one’s debts, there would still be a paper currency.

But on the drug standard, the city was poor. It had none of the new paper money at all, though it would, of course, sell all its metallic germanium at once to get a supply. Possibly its germanium-based paper money might also be sold, against Earth redemption, at about a fifth of the current market value of the metallic equivalent if the Acolytes cared to bother with redeeming it.

The actual drugs on board the city could not be traded against. They were necessary to maintain the life of the city. Amalfi winced to think of the size of the bite medical care was going to take out of every individual’s budget under the new economy. The anti-agathics, in particular, would pose a terrifying dilemma: shall I use my anti- agathic credits now, as money, to relieve my current money miseries, or shall I continue to live in poverty in order to prolong my life? …

Remorselessly, Amalfi drove one consequence after another through the stony corridors of his skull, like a priest wielding the whip behind lowing sacrifices. The city was poor. It could find no work among the Acolyte stars at a rate which would make the work justifiable. It could look for work nowhere else without a new spin-dizzy.

That left only the jungle. There was no place else to go.

Amalfi had never set down in a jungle before, and the thought made him wipe the palms of his hands unconsciously upon his thighs. The word in his mind—it had always been there, he knew, lying next to the word “jungle”—was never. The city must always pay its own way, it must always come whole out of any crisis, it must always pull its own weight …

Those emblems of conduct were now cliches, in which never had turned out to be a
