Robert Heinlein: Tunnel In The Sky

This was no poverty-stricken band of refugees chivvied along by police; here each family had its own wagon....ong, sweeping, boat-tight Conestogas drawn by three-pair teams and housed in sturdy glass canvas square and businesslike Studebakers with steel bodies, high mudcutter wheels, and pulled by one or two-pair teams. The draft animals were Morgans and lordly Clydesdales and jug-headed Missouri mules with strong shoulders and shrewd, suspicious eyes. Dogs trotted between wheels, wagons were piled high with household goods and implements and children, poultry protested the indignities of fate in cages tied on behind, and a little Shetland pony, riderless but carrying his saddle and just a bit too tall to run underneath with the dogs, stayed close to the tailgate of one family's rig.

Rod wondered at the absence of cattle and stepped up the speaker again. But the announcer was still droning about the fertility of Australasians; he muted it again and watched. Wagons had moved onto the floor and taken up tight echelon position close to the gate, ready to move, with the tail of the train somewhere out of sight below. The gate was not yet ready and drivers were getting down and gathering at the Salvation Army booth under the skirts ot the Goddess of Liberty, for a cup of coffee and some banter. It occurred to Rod that there probably was no coffee where they were going and might not be for years, since Terra never exported food - on the contrary, food and fissionable metals were almost the only permissible imports; until an Outland colony produced a surplus of one or the other it could expect precious little help from Terra.

It was extremely expensive in terms of uranium to keep an interstellar gate open and the people in this wagon train could expect to be out of commercial touch with Earth until such a time as they had developed surpluses valuable enough in trade to warrant reopening the gate at regular intervals. Until that time they were on their own and must make do with what they could take with them... which made horses more practical than helicopters, picks and shovels more useful than bulldozers. Machinery gets out of order and requires a complex technology to keep it going- but good old "hayburners" keep right on breeding, cropping grass, and pulling loads.

Deacon Matson had told the survival class that the real hardships of primitive Outlands were not the lack of plumbing, heating, power, light, nor weather conditioning, but the shortage of simple things like coffee and tobacco.

Rod did not smoke and coffee he could take or let alone; he could not imagine getting fretful over its absence. He scrunched down in his seat, trying to see through the gate to guess the cause of the hold up. He could not see well, as the arching canvas of a prairie schooner blocked his view, but it did seem that the gate operator had a phase error; it looked as if the sky was where the ground ought to be. The extradimensional distortions necessary to match places on two planets many light-years apart were not simply a matter of expenditure of enormous quantities of energy; they were precision problems fussy beyond belief, involving high mathematics and high art-the math was done by machine but the gate operator always had to adjust the last couple of decimal places by prayer and intuition.

In addition to the dozen-odd proper motions of each of the planets involved, motions which could usually be added and canceled out, there was also the rotation of each planet. The problem was to make the last hyperfold so that the two planets were internally tangent at the points selected as gates, with their axes parallel and their rotations in the same direction. Theoretically it was possible to match two points in contra-rotation, twisting the insubstantial fabric of space-time in exact step with "real' motions; practically such a solution was not only terribly wasteful of energy but almost unworkable- the ground surface beyond the gate tended to skid away like a slidewalk and tilt at odd angles.

Rod did not have the mathematics to appreciate the difficulties. Being only about to finish high school his training had gone no farther than tensor calculus, statistical mechanics, simple transfinities, generalized geometries of six dimensions, and, on the practical side, analysis for electronics, primary cybernetics and robotics, and basic design of analog computers; he had had no advanced mathematics as yet. He was not aware of his ignorance and simply concluded that the gate operator must be thumb-fingered. He looked back at the emigrant party.

The drivers were still gathered at the booth, drinking coffee and munching doughnuts. Most of the men were growing beards; Rod concluded from the beavers that the party had been training for several months. The captain of the party sported a little goatee, mustaches, and rather long hair, but it seemed to Rod that he could not be many years older than Rod himself. He was a professional, of course, required to hold a degree in Outlands arts- hunting, scouting, jackleg mechanics, gunsmithing, farming, first aid, group psychology, survival group tactics, law, and a dozen other things the race has found indispensable when stripped for action.

This captain's mount was a Palomino mare, lovely as a sunrise, and the captain was dressed as a California don of an earlier century-possibly as a compliment to his horse. A warning light flashed at the gate's annunciator panel and he swung into saddle, still eating a doughnut, and cantered down the wagons for a final inspection, riding toward Rod. His back was straight, his seat deep and easy, his bearing confident. Carried low on a fancy belt he wore two razor guns, each in a silver-chased holster that matched the ornate silver of his bridle and saddle.

Rod held his breath until the captain passed out of sight under the balcony, then sighed and considered studying to be like him, rather than for one of the more intellectual Outlands professions. He did not know just what he did want to be... except that he meant to get off Earth as soon as he possibly could and get out there where things were going on!

Which reminded him that the first hurdle was tomorrow; in a few days he would either be eligible to matriculate for whatever it was he decided on, or he would be-but no use worrying about that. He remembered uneasily that it was getting late and he had not even decided on equipment, nor picked his weapons. This party captain carried razor guns; should he carry one? No, this party would fight as a unit, if it had to fight. Its leader carried that type of weapon to enforce his authority-not for solo survival. Well, what should he take?

A siren sounded and the drivers returned to their wagons. The captain came back at a brisk trot. "Reins up!" he called out. "Reeeeeeiiiins up!" He took station by the gate, facing the head of the train; the mare stood quivering and tending to dance.

The Salvation Army lassie came out from behind her counter carrying a baby girl. She called to the party captain but her voice did not carry to the balcony.

The captain's voice did carry. "Number four! Doyle! Come get your child!" A red-headed man with a spade beard climbed down from the fourth wagon and sheepishly reclaimed the youngster to a chorus of cheers and cat calls. He passed the baby up to his wife, who upped its skirt and commenced paddling its bottom. Doyle climbed to his seat and took his reins.

"Call off!" the captain sang out.

"One."

"Tuh!"

"Three!"

"Foah!"

"Five!"

The count passed under the balcony, passed down the chute out of hearing. In a few moments it came back, running down this time, ending with a shouted "ONE!" The captain held up his right arm and watched the lights of the order panel.

A light turned green. He brought his arm down smartly with a shout of "Roll 'em! Ho!" The Palomino took off like a race horse, cut under the nose of the nigh lead horse of the first team, and shot through the gate.
