"How did the Joneses get that way? Many of you were too young when this long war began to be aware of the facts. Since then, wartime disruption of education and normal communications facilities has left you in the dark. This is the authoritative statement in simple language that explains why we fight.
"This planet was colonized, presumably from the quasi-legendary planet Earth. (The famous Earth Archives Building, incidentally, is supposed to derive its puzzling name from this fact.) It is presumed that the number of colonists was originally small, probably in the hundreds. Though the number of human beings on the planet increased enormously as the generations passed, genetically the population remained small. The same ones (heredity units) were combined and reshuffled in varying combinations, but no new ones were added. Now, it is a law of genetics that in small populations, variations tend to smooth out and every member of the population tends to become like every other member. So-called unfixed genes are lost as the generations pass; the end product of this process would theoretically be a population hi which every member had exactly the same genes as every other member. This is a practical impossibility, but the Joneses whom we fight are a tragic demonstration of the fact that the process need not be pushed to its ultimate extreme to dislocate the life of a planet and cause endless misery to its dwellers.
"From our very earliest records there have been Joneses. It is theorized that this gangling redheaded type was well represented aboard the original colonizing ship, but some experts believe one Jones type and the workings of chance would be sufficient to produce the unhappy situation of type-dominance.
"Some twenty-five years ago Joneses were everywhere among us and not, as now, withdrawn to South Continent and organized into a ruthless aggressor nation. They made up about thirty per cent of the population and had become a closely knit organization devoted to mutual help. They held the balance of political power in every election from the municipal to the planetary level and virtually monopolized production and finance. There were fanatics and rabble-rousers among them who readily exploited a rising tide of discontent over a series of curbing laws, finally pushed through by a planetary majority, united at last in self-defense against the rapacity and ruthless self-interest of the Joneses.
"The Joneses withdrew en masse to South Continent. Some sincerely wished them well; others scoffed at the secession as a sulky and childish gesture. Only a handful of citizens guessed the terrible truth, and were laughed at for their pains. Five years after their withdrawal the Joneses returned across the Vandemeer Peninsula and the war had begun.
"A final word. There has been much loose talk among the troops about the slogan of the Joneses, which goes LT=L0e-T/2N. Some uninformed people actually believe it is an invocation which gives the Joneses supernatural power and invulnerability. It is not. It is merely an ancient and well-known formula in genetics which quantitatively describes the loss of unfixed genes from a population. By mouthing this formula, the Joneses are simply expressing in a compact way their ruthless determination that all genes except theirs shall disappear from the planet and the Joneses alone survive. In the formula LT means the number of genes after the lapse of T years, L0 means the original number of genes, e means the base of the natural system of logarithms and N means number of generations."
The surgeon said slowly and with wonder: "So that was my God!" He stretched out his hands before him. The fingers were rock-steady.
Ross left him and paced the corridor uneasily. Fine. Now he knew. Lost genes in genetically small populations. On Halsey's Planet, some fertility gene, no doubt. On Azor, a male-sex-linked gene that provides men with the backbone required to come out ahead in the incessant war of the genders? Bernie was a gutless character. Here, all too many genes determining somatotype. On the planets that had dropped out of communication, who knew?
Scientific-thought genes? Sex-drive-determining genes?
One thing was clear: any gene-loss was bad for the survival of a planetary colony. Evolution had———on Earth ———worked out in a billion trial-and-error years a working mechanism, man.
Man exhibited a vast range of variation, which was why he survived almost any conceivable catastrophe.
Reduce man to a single type and he is certain to succumb, sooner or later, to the inevitable disaster that his one type cannot cope with.
The problem, now stated clearly, was bigger than he had dreamed. And now he knew only the problem—not the solution.
Go to Earth.
Well, he had tried. There had been no flaw in his calculations, no failure in setting up the Wesley panel. Yet—this was Jones, not Earth; the city was only a city, not the planet that the star charts logged. And the planet, beyond all other considerations, was less like Earth than any conceivable chart error could account for. Gravitation, wrong; atmosphere, wrong; flora and fauna, wrong.
So. Eliminate the impossible, and what remains, however unlikely, is true. So there had been a flaw in his calculations. And the way to check that, once and for all, was to get back to the starship.
Ross wheeled and went back into the book room. "Doc," he called, "how do we get out of here?"
The answer was: on their bellies. They trudged through the forest for hours, skirting the road, hiding whenever a suspicious noise gave warning that someone might be in the vicinity. The Peepeece knew they were in the woods; there was no doubt of that. And as soon as they got past the tabu area, they had to crawl.
It was well past dark before Ross and the doctor, scratched and aching, got to the tiny hamlet of Jonesie-on-the-Pike. By the light from the one window in the village that gave any signs of life, the doctor took a single horrified look at Ross and shuddered. "You wait here," he ordered. "Hide under a bush or something—your beard rubbed off."
Ross watched the doctor rap on the door and be admitted. He couldn't hear the conversation that followed, but he saw the doctor's hand go to his pocket, then clasp the hand of the figure hi the doorway. That was the language all the galaxy understood, Ross realized; he only hoped that the householder was an honest man—i. e., one who would stay bribed, instead of informing the Peepeece on them. It was beyond doubt that their descriptions had long since been broadcast; the road must have been lined with TV scanners on the way in.
The door opened again, and the doctor walked briskly out. He strode out into the street, walked half a dozen paces down the road, and waited for Ross to catch up with him. "Okay," the doctor whispered. "They'll pick us up in half an hour, down the road about a quarter of a mile. Let's go."
"What about the man you were talking to?" Ross asked. "Won't he turn us hi?"
The doctor chuckled. "I gave him a drink of Jones's Juice out of my private stock," he said. "No, he won't turn anybody in, at least not until he wakes up."
Ross nodded invisibly hi the dark. He had a thought, and suppressed it. But it wouldn't stay down.
Cautiously he let it seep through his subconscious again, and looked it over from every angle.
No, there wasn't any doubt of it. Things were definitely looking up!
Ben Jones roared, "Just what the hell do you think you're doing, Doc?"
The doctor pushed Ross through the doorway and turned to face the other Jones. He asked mildly,
