Rod did not listen. He had long since sent for every free item and most of the non-free ones issued by the Commission for Emigration and Trade. Just now he was wondering why the gate to New Canaan had not relaxed.
He found out at once. Stock barricades rose up out of the floor, forming a fenced passage from gate four to the chute under him. Then a herd of cattle filled the gate and came flooding toward him, bawling and snorting. They were prime Hereford steers, destined to become tender steaks and delicious roasts for a rich but slightly hungry Earth. After them and among them rode New Canaan cowpunchers armed with long goads with which they urged the beasts to greater speed—the undesirability of running weight off the animals was offset by the extreme cost of keeping the gate open, a cost which had to be charged against the cattle.
Rod discovered that the speaker had shut itself off; the half hour he had paid for was finished. He sat up with sudden guilt, realizing that he would have to hurry or he would be late for supper. He rushed out, stepping on feet and mumbling apologies, and caught the slide-way to Hoboken Gate.
This gate, being merely for Terra-surface commuting, was permanently dilated and required no operator, since the two points brought into coincidence were joined by a rigid frame, the solid Earth. Rod showed his commuter’s ticket to the electronic monitor and stepped through to Arizona, in company with a crowd of neighbors.
“The (almost) solid Earth—” The gate robot took into account tidal distortions but could not anticipate minor seismic variables. As Rod stepped through he felt his feet quiver as if to a small earthquake, then the terra was again firma. But he was still in an airlock at sea-level pressure. The radiation from massed bodies triggered the mechanism, the lock closed and air pressure dropped. Rod yawned heavily to adjust to the pressure of Grand Canyon plateau, North Rim, less than three quarters that of New Jersey. But despite the fact that he made the change twice a day he found himself rubbing his right ear to get rid of an ear ache.
The lock opened, he stepped out. Having come two thousand miles in a split second he now had ten minutes by slide tube and a fifteen minute walk to get home. He decided to dogtrot and be on time after all. He might have made it if there had not been several thousand other people trying to use the same facilities.

The Fifth Way
ROCKET SHIPS DID NOT CONQUER SPACE; THEY MERELY challenged it. A rocket leaving Earth at seven miles per second is terribly slow for the vast reaches beyond. Only the Moon is reasonably near—four days, more or less. Mars is thirty-seven weeks away, Saturn a dreary six years, Pluto an impossible half century, by the elliptical orbits possible to rockets.
Ortega’s torch ships brought the Solar System within reach. Based on mass conversion, Einstein’s deathless e = Mc², they could boost for the entire trip at any acceleration the pilot could stand. At an easy one gravity the inner planets were only hours from Earth, far Pluto only eighteen days. It was a change like that from horseback to jet plane.
The shortcoming of this brave new toy was that there was not much anywhere to go. The Solar system, from a human standpoint, is made up of remarkably unattractive real estate—save for lovely Terra herself, lush and green and beautiful. The steel-limbed Jovians enjoy gravity 2.5 times ours and their poisonous air at inhuman pressure keeps them in health. Martians prosper in near vacuum, the rock lizards of Luna do not breathe at all. But these planets are not for men.
Men prosper on an oxygen planet close enough to a G-type star for the weather to cycle around the freezing point of water…that is to say, on Earth.
When you are already there why go anywhere? The reason was babies, too many babies. Malthus pointed it out long ago; food increases by arithmetical progression, people increase by geometrical progression. By World War I half the world lived on the edge of starvation; by World War II Earth’s population was increasing by 55,000 people every day; before World War III, as early as 1954, the increase had jumped to 100,000 mouths and stomachs per day, 35,000,000 additional people each year…and the population of Terra had climbed well beyond that which its farm lands could support.
The hydrogen, germ, and nerve gas horrors that followed were not truly political. The true meaning was more that of beggars fighting over a crust of bread.
The author of Gulliver’s Travels sardonically proposed that Irish babies be fattened for English tables; other students urged less drastic ways of curbing population—none of which made the slightest difference. Life, all life, has the twin drives to survive and to reproduce. Intelligence is an aimless byproduct except as it serves these basic drives.
But intelligence can made to serve the mindless demands of life. Our Galaxy contains in excess of one hundred thousand Earth-type planets, each as warm and motherly to men as sweet Terra. Ortega’s torch ships could reach the stars. Mankind could colonize, even as the hungry millions of Europe had crossed the Atlantic and raised more babies in the New World.
Some did…hundreds of thousands. But the entire race, working as a team, cannot build and launch a hundred ships a day, each fit for a thousand colonists, and keep it up day after day, year after year, time without end. Even with the hands and the will (which the race never had) there is not that much steel, aluminum, and uranium in Earth’s crust. There is not one hundredth of the necessary amount.
But intelligence can find solutions where there are none. Psychologists once locked an ape in a room, for which they had arranged only four ways of escaping. Then they spied on him to see which of the four he would find.
The ape escaped a fifth way.
Dr. Jesse Evelyn Ramsbotham had not been trying to solve the baby problem; he had been trying to build a time machine. He had two reasons: first, because time machines are an impossibility; second, because his hands would sweat and he would stammer whenever in the presence of a nubile female. He was not aware that the first reason was compensation for the second, in fact he was not aware of the second reason—it was a subject his conscious mind avoided.
It is useless to speculate as to the course of history had Jesse Evelyn Ramsbotham’s parents had the good sense to name their son Bill instead of loading him with two girlish names. He might have become an All-American halfback and ended up selling bonds and adding his quota of babies to a sum already disastrous. Instead he became a mathematical physicist.
Progress in physics is achieved by denying the obvious and accepting the impossible. Any nineteenth century physicist could have given unassailable reasons why atom bombs were impossible if his reason were not affronted at the question; any twentieth century physicist could explain why time travel was incompatible with the real world of space-time. But Ramsbotham began fiddling with the three greatest Einsteinian equations, the two relativity equations for distance and duration and the mass-conversion equation; each contained the velocity of light. “Velocity” is first derivative, the differential of distance with respect to time; he converted those equations into differential equations, then played games with them. He would feed the results to the Rakitiac computer, remote successor to Univac, Eniac and Maniac. While he was doing these things his hands never sweated nor did he stammer, except when he was forced to deal with the young lady who was chief programmer for the giant computer.
His first model produced a time-stasis or low-entropy field no bigger than a football—but a lighted cigarette placed inside with full power setting was still burning a week later. Ramsbotham picked up the cigarette, resumed smoking and thought about it.
Next he tried a day-old chick, with colleagues to witness. Three months later the chick was unaged and no hungrier than chicks usually are. He reversed the phase relation and cut in power for the shortest time he could manage with his bread-boarded hook-up.
In less than a second the newly-hatched chick was long dead, starved and decayed.
He was aware that he had simply changed the slope of a curve, but he was convinced that he was on the track of true time travel. He never did find it, although once he thought that he h
ad—he repeated by request his demonstration with a chick for some of his colleagues; that night two of them picked the lock on his lab, let the little thing out and replaced it with an egg. Ramsbotham might have been permanently convinced that he had found time travel and then spent the rest of his life in a blind alley had they not cracked the egg and showed him that it was hard-boiled.
But he did not give up. He made a larger model and tried to arrange a dilation, or anomaly (he did not call it a “Gate”) which would let him get in and out of the field himself.
When he threw on power, the space between the curving magnetodes of his rig no longer showed the wall beyond, but a steaming jungle. He jumped to the conclusion that this must be a forest of the Carboniferous Period. It had often occurred to him that the difference between space and time might simply be human prejudice, but this was not one of the times; he believed what he wanted to believe.
He hurriedly got a pistol and with much bravery and no sense crawled between the magnetodes.
Ten minutes later he was arrested for waving firearms around in Rio de Janeiro’s civic botanical gardens. A lack of the Portuguese language increased both his difficulties and the length of time he spent in a tropical pokey, but three days later through the help of the North American consul he was on his way home. He thought and filled notebooks with equations and question marks on the whole trip.
The short cut to the stars had been found.
Ramsbotham’s discoveries eliminated the basic cause of war and solved the problem of what to do with all those dimpled babies. A hundred thousand planets were no farther away than the other side of the street. Virgin continents, raw wildernesses, fecund jungles, killing deserts, frozen tundras, and implacable mountains lay just beyond the city gates, and the human race was again going out where the street lights do not shine, out where there was no friendly cop on the corner nor indeed a corner, out where there were no well-hung, tender steaks, no boneless hams, no packaged, processed foods suitable for delicate minds and pampered bodies. The biped omnivore again had need of his biting, tearing, animal teeth, for the race was spilling out (as it had so often before) to kill or be killed, eat or be eaten.
But the human race’s one great talent is survival. The race, as always, adjusted to conditions, and the most urbanized, mechanized, and civilized, most upholstered and luxurious culture in all history trained its best children, its potential leaders, in primitive pioneer survival—man naked against nature.
Rod Walker knew about Dr. J. E. Ramsbotham, just as he knew about Einstein, Newton, and Columbus, but he thought about Ramsbotham no oftener than he thought about Columbus. These were figures in books, each larger than life and stuffed with straw, not real. He used the Ramsbotham Gate between Jersey and the Arizona Strip without thinking of its inventor the same way his ancestors used elevators without thinking of the name “Otis.” If he thought about the miracle at all, it was a half-formed irritation that the Arizona side of Hoboken Gate was so far from his parents’ home. It was known as Kaibab Gate on this side and was seven miles north of the Walker residence.
At the time the house had been built the location was at the extreme limit of tube delivery and other city utilities. Being an old house, its living room was above ground, with only bedrooms, pantry, and bombproof buried. The living room had formerly stuck nakedly above ground, an ellipsoid monocoque shell, but, as Greater New York spread, the neighborhood had been zoned for underground apartments and construction above ground which would interfere with semblance of virgin forest had been forbidden.
The Walkers had gone along to the extent of covering the living room with soil and planting it with casual native foliage, but they had refused to cover up their view window. It was the chief charm of the house, as it looked out at the great canyon. The community corporation had tried to coerce them into covering it up and had offered to replace it with a simulacrum window such as the underground apartments used, with a relayed view of the canyon. But Rod’s father was a stubborn man and maintained that with weather, women, and wine there was nothing “just as good.” His window was still intact.
Rod found the family sitting in front of the window, watching a storm work its way up the canyon—his mother, his father, and, to his great surprise, his sister. Helen was ten years older than he and an assault captain in the Amazons; she was seldom home.
The warmth of his greeting was not influenced by his realization that her arrival would probably cause his own lateness to pass with little comment. “Sis! Hey, this is swell—I thought you were on Thule.”
“I was…until a few hours ago.” Rod tried to shake hands; his sister gathered him in a bear hug and bussed him on the mouth, squeezing him against the raised ornaments of her chrome corselet. She was still in uniform, a fact that caused him to think that she had just arrived—on her rare visits home she usually went slopping around in an old bathrobe and go-ahead slippers, her hair caught up in a knot. Now she was still in dress armor and kilt and had dumped her side arms, gauntlets, and plumed helmet on the floor.
She looked him over proudly. “My, but you’ve grown! You’re almost as tall as I am.”
“I’m taller.”
“Want to bet? No, don’t try to wiggle away from me; I’ll twist your arm. Slip off your shoes and stand back to back.”
“Sit down, children,” their father said mildly. “Rod, why were you late?”
“Uh…” He had worked out a diversion involving telling about the examination coming up, but he did not use it as his sister intervened.
“Don’t heckle him, Pater. Ask for excuses and you’ll get them. I learned that when I was a sublieutenant.”
“Quiet, daughter. I can raise him without your help.”
Rod was surprised by his father’s edgy answer, was more surprised by Helen’s answer: “So? Really?” Her tone was odd.
Rod saw his mother raise a hand, seem about to speak, then close her mouth. She looked upset. His sister and father looked at each other; neither spoke. Rod looked from one to the other, said slowly, “Say, what’s all this?”
His father glanced at him. “Nothing. We’ll say no more about it. Dinner is waiting. Coming, dear?” He turned to his wife, handed her up from her chair, offered her his arm.
“Just a minute,” Rod said insistently. “I was late because I was hanging around the Gap.”
“Very well. You know better, but I said we would say no more about it.” He turned toward the lift.
“But I wanted to tell you something else, Dad. I won’t be home for the next week or so.”
“Very well—eh? What did you say?”
“I’ll be away for a while, sir. Maybe ten days or a bit longer.”
His father looked perplexed, then shook his head. “Whatever your plans are, you will have to change them. I can’t let you go away at this time.”
“But, Dad—”
“I’m sorry, but that is definite.”
“But, Dad, I have to!”
“No.”
Rod looked frustrated. His sister said suddenly, “Pater, wouldn’t it be well to find out why he wants to be away?”
“Now, daughter—”
“Dad, I’m taking my solo survival, starting tomorrow morning!”
Mrs. Walker gasped, then began to weep. Her husband said, “There, there, my dear!” then turned to his son and said harshly, “You’ve upset your mother.”
“But, Dad, I…” Rod shut up, thinking bitterly that no one seemed to give a hoot about his end of it. After all, he was the one who was going to have to sink or swim. A lot they knew or—
“You see, Pater,” his sister was saying. “He does have to be away. He has no choice, because—”
“I see nothing of the sort! Rod, I meant to speak about this earlier, but I had not realized that your test would take place so soon. When I signed permission for you to take that course, I had, I must admit, a mental reservation. I felt that the experience would be valuable later…when and if you took the course in
college. But I never intended to let you come up against the final test while still in high school. You are too young.”
Rod was shocked speechless. But his sister again spoke for him. “Fiddlesticks!”
“Eh? Now, daughter, please remember that—”
“Repeat fiddlesticks! Any girl in my company has been up against things as rough and many of them are not much older than Buddy. What are you trying to do, Pater? Break his nerve?”
“You have no reason to… I think we had best discuss this later.”
“I think that is a good idea.” Captain Walker took her brother’s arm and they followed their parents down to the refectory. Dinner was on the table, still warm in its delivery containers; they took their places, standing, and Mr. Walker solemnly lighted the Peace Lamp. The family was evangelical Monist by inheritance, each of Rod’s grandfathers having been converted in the second great wave of proselyting that swept out of Persia in the last decade of the previous century, and Rod’s father took seriously his duties as family priest.
As the ritual proceeded Rod made his responses automatically, his mind on this new problem. His sister chimed in heartily but his mother’s answers could hardly be heard.
Nevertheless the warm symbolism had its effect; Rod felt himself calming down. By the time his father intoned the last “—one Principle, one family, one flesh!” he felt like eating. He sat down and took the cover off his plate.
