I PUT MY BLUE GENES ON

It had taken three weeks to get there-- longer than any man in living memory had been in space, and there were four of us crammed into the little Hunter III skipship. It gave us a hearty appreciation for the pioneers, who had had to crawl across space at a tenth of the speed of light. No wonder only three colonies ever got founded. Everybody else must have eaten each other alive after the first month in space.

Harold had taken a swing at Amauri the last day, and if we hadn't hit the homing signal I would have ordered the ship turned around to go home to N£ncamais, which was mother and apple pie to everybody but me-- I'm from Pennsylvania. But we got the homing signal and set the computer to scanning the old maps, and after a few hours found ourselves in stationary orbit over Prescott, Arizona.

At least that's what the geologer said, and computers can't lie. It didn't look like what the old books said Arizona should look like.

But there was the homing signal, broadcasting in Old English: "God bless America, come in, safe landing guaranteed." The computer assured us that in Old English the word guarantee was not obscene, but rather had something to do with a statement being particularly trustworthy-- we had a chuckle over that one.

But we were excited, too. When great-great-great-great to the umpteenth power grandpa and grandma upped their balloons from old Terra Firma eight hundred years ago, it had been to escape the ravages of microbiological warfare that was just beginning (a few germs in a sneak attack on Madagascar, quickly spreading to epidemic proportions, and South Africa holding the world ransom for the antidote; quick retaliation with virulent cancer; you guess the rest). And even from a couple of miles out in space, it was pretty obvious that the war hadn't stopped there. And yet there was this homing signal.

"Obviamente autom tica," Amauri observed.

"Que m quina, que nƒo pofa em tantos anos, bichinha! Nƒo acredito!" retorted Harold, and I was afraid I might have a rerun of the day before.

"English," I said. "Might as well get used to it. We'll have to speak it for a few days, at least."

Vladimir sighed. "Merda."

I laughed. "All right, you can keep your scatological comments in lingua deporto."

"Are you so sure there's anybody alive down there?" Vladimir asked.

What could I say? That I felt it in my bones? So I just threw a sponge at him, which scattered drinking water all over the cabin, and for a few minutes we had a waterfight. I know, discipline, discipline. But we're not a land army up here, and what the hell. I'd rather have my crew acting like crazy children than like crazy grown-ups.

Actually, I didn't believe that at the level of technology our ancestors had reached in 1992 they could build a machine that would keep running until 2810.

Somebody had to be alive down there-- or else they'd gotten smart. Again, the surface of old Terra didn't give many signs that anybody had gotten smart.

So somebody was alive down there. And that was exactly what we had been sent to find out.

They complained when I ordered monkeysuits.

"That's old Mother Earth down there!" Harold argued. For a halibut with an ike of

150 he sure could act like a baiano sometimes.

"Show me the cities," I answered. "Show me the millions of people running around taking the sun in their rawhide summer outfits."

"And there may be germs," Amauri added, in his snottiest voice, and immediately I had another argument going between two men brown enough to know better.

"We will follow," I said in my nasty captain's voice, "standard planetary procedure, whether it's Mother Earth or mother--"

And at that moment the monotonous homing signal changed.

"Please respond, please identify, please respond, or we'll blast your asses out of the sky."

We responded. And soon afterward found ourselves in monkeysuits wandering around in thick pea soup up to our navels (if we could have located our navels without a map, surrounded as they were with lifesaving devices) waiting for somebody to open a door.

A door opened and we picked ourselves up off a very hard floor. Some of the pea soup had fallen down the hatch with us. A gas came into the sterile chamber where we waited, and pretty soon the pea soup settled down and turned into mud.

"Mariajoseijesus!" Amauri muttered. "Aquela merda vivia!"

"English," I muttered into the monkey mouth, "and clean up your language."

"That crap was alive," Amauri said, rephrasing and cleaning up his language.

"And now it isn't, but we are." It was hard to be patient.

For all we knew, what passed for humanity here liked eating spacemen. Or sacrificing them to some local deity. We passed a nervous four hours in that cubicle. And I had already laid about five hopeless escape plans when a door opened, and a person appeared.

He was dressed in a white farmersuit, or at least close to it. He was very short, but smiled pleasantly and beckoned. Proof positive. Living human beings. Mission successful. Now we know there was no cause for rejoicing, but at that moment we rejoiced. Backslapping, embracing our little host (afraid of crushing him for a moment), and then into the labyrinth of U.S. MB Warfare Post 004.

They were all very small-- not more than 140 centimeters tall-- and the first thought that struck me was how much humanity had grown since then. The stars must agree with us, I thought.

Till quiet, methodical Vladimir, looking as always, white as a ghost, pointedly turned a doorknob and touched a lightswitch (it actually was mechanical). They were both above eye level for our little friends. So it wasn't us colonists who had grown-- it was our cousins from old Gaea who had shrunk.

We tried to catch them up on history, but all they cared about was their own politics. "Are you American?" they kept asking.

"I'm from Pennsylvania," I said, "but these humble-butts are from N£ncamais.

They didn't understand.

"N£ncamais. It means 'never again.' In lingua deporto."

Again puzzled. But they asked another question.

"Where did your colony come from?" One-track minds.

"Pennsylvania was settled by Americans from Hawaii. We lay no bets as to why they named the damned planet Pennsylvania--"

One of the little people piped up, "That's obvious. Cradle of liberty. And them?"

"From Brazil," I said.

They conferred quietly on that one, and then apparently decided that while Brazilian ancestry wasn't a capital offense, it didn't exactly confer human status.

From then on, they made no attempt to talk to my crew, just watched them carefully, and talked to me.

Me they loved.

"God bless America," they said.

I felt agreeable. "God bless America," I answered.

Then, again in unison, they made an obscene suggestion as to what I should do with the Russians. I glanced at my compatriots and fellow travelers and shrugged. I repeated the little folks' wish for the Russian's sexual bliss.

Fact time. I won't bore by repeating all the clever questioning and probing that elicited the following information. Partly because it didn't take any questioning.

They seemed to have been rehearsing for years what they would say to any visitors from outer space, particularly the descendants of the long-lost colonists. It went this way: Germ warfare had began in earnest about three years after we left. Three very cleverly designed cancer viruses had been loosed on the world, apparently by no one at all, since both the Russians and the Americans denied it and the Chinese were all dead. That was when the scientists knuckled down and set to work.

Recombinant DNA had been a rough enough science when my ancestors took off for the stars-- and we hadn't developed it much since then. When you're developing raw planets you have better things to do with your time. But under the pressure of warfare, the science of do-it-yourself genetics had a field day on planet Earth.
