Ergo: X = 10to the power of 9

McLeod drew the equations on the bar with the tip of a wet forefinger,

then rubbed them out quickly.

A billion copies in the first year. He should have seen it. He should

have understood.

How many planets were there in the galaxy?

How many people on each planet?

Communication, even at ultralight velocities, would be necessarily

slow. The galaxy was just too big to be compassed by the human

mind--or even by the mind of a Galactic, McLeod suspected.

How do you publish a book for Galactic, for galaxy-wide, consumption?

How long does it take to saturate the market on each planet? How long

does it take to spread the book from planet to planet? How many people

were there on each planet who would buy a good book? Or, at least, an

entertaining one.

McLeod didn't know, but he suspected that the number was huge. McLeod

was a zoologist, not an astronomer, but he read enough on astronomy to

know that the estimated number of Earth-type planets alone--according

to the latest theory--ran into the tens of millions or hundreds of

millions. The--

A man sat down on the stool next to McLeod and said something loud

enough and foul enough to break the zoologist's train of thought.

"Gimme a shot, Leo," he added in an angry voice.

"Sure, Pete," the bartender said. "What's the trouble?"

"_Tourists_," Pete said with a snarl. "Laffin' attus alla time like we

was monkeys inna zoo! Bunch 'em come inta day." He downed his whiskey

with a practiced flip of the wrist and slammed it on the bar. Leo

refilled it immediately. "I shunt gripe, I guess. Gotta haffa credit

offen 'em." He slapped down a five dollar bill as though it had

somehow been contaminated.

The bar became oddly quiet. Everyone had heard Pete. Further,

everyone had heard that another shipload of Galactics had landed and

were, at the moment, enjoying the sights of New York. A few of them

knew that Pete was the bell-captain in one of the big midtown hotels.

McLeod listened while Pete expounded on the shame he had had to

undergo to earn half a credit--a lousy five bucks.

McLeod did some estimating. Tourists--the word had acquired an even

more pejorative sense than it had before, and now applied only to

Galactics--bought nothing, but they tipped for services, unless the

services weren't wanted or needed. Pete had given them information

that they hadn't had before--where to find a particular place. All in

all, the group of fifteen Galactics had given out five or six credits

in such tips. Say half a credit apiece. There were, perhaps, a hundred

Galactics in this shipload. That meant fifty credits. Hm-m-m.

They didn't need anyone to carry their bags; they didn't need anyone

to register them in hotels; they didn't need personal service of that

kind. All they wanted to do was look. But they wouldn't pay for

looking. They had no interest in Broadway plays or the acts in the

night-clubs--at least, not enough to induce them to pay to see them.

This particular group had wanted to see a hotel. They had wandered

through it, looking at everything and laughing fit to kill at the

carpets on the floor and the electric lighting and such. But when the

management had hinted that payment for such services as letting them

look should be forthcoming, they had handed half a credit to someone

and walked out. Then they had gone to the corner of Fifty-first and

Madison and looked for nothing.

Fifty credits for a shipload. Three shiploads a year. Hell, give 'em

the benefit of the doubt and say _ten_ shiploads a year. In a hundred

years, they'd add another fifty thousand to Earth's resources.

McLeod grinned.

And waited.

They came for him, eventually, as McLeod had known they would.

But they came long before he had expected. He had given them six

months at the least. They came for him at the end of the third month.

It was Jackson, of course. It would have to be Jackson. He walked into

the cheap little room McLeod had rented, followed by his squad of men.

He tossed a peculiar envelope on the bed next to McLeod.

"Letter came for you, humorist. Open it."

McLeod sat on the edge of the bed and read the letter. The envelope

had already been opened, which surprised him none.

It looked very much like an ordinary business letter--except that

whatever they used for paper was whiter and tougher than the paper he

used.

He was reminded of the time he had seen a reproduction of a Thirteenth

Century manuscript alongside the original. The copy had been set up

in a specially-designed type and printed on fine paper. The original

had been handwritten on vellum.

McLeod had the feeling that if he used a microscope on this letter the

lines and edges would be just as precise and clear as they appeared to

the naked eye, instead of the fuzziness that ordinary print would

show.

The way you tell a synthetic ruby from a natural ruby is to look for

flaws. The synthetic doesn't have any.

This letter was a Galactic imitation of a Terran business letter.

It said:

Dear Mac,

I am happy to report that your book, "Interstellar Ark," is

a smash hit. It looks as though it is on its way to becoming

a best seller. As you already know by your royalty

statement, over a billion copies were sold the first year.

That indicates even better sales over the years to come as

the reputation of the book spreads. Naturally, our

advertising campaign will remain behind it all the way.

Congratulations.

Speaking of royalty checks, there seems to be some sort of

irregularity about yours. I am sorry, but according to

regulations the check must be validated in the presence of

your Galactic Resident before it can be cashed. Your

signature across the back of it doesn't mean anything to our

bankers.

Just go to your Galactic Resident, and he'll be happy to

take care of the matter for you. That's what he's there for.

The next check should come through very shortly.

All the best,

Clem.

_Better and better_, McLeod thought. He hadn't expected to be able to

do anything until his next royalty check arrived. But now--
