"Oh, he wouldn't dare! I'd scream."

I wasn't so sure. I remembered those four hundred million miles of dirty dishes. I decided that, if the Captain said "Frog," I'd hop.

If Captain Harkness was a monarch, he didn't seem anxious to rule; the first thing he had us do was to hold an election and set up a ship's council. After that we hardly laid eyes on him.

Everybody over eighteen could vote. The rest of us got to vote, too; we were told to setup a junior council—not that it was ever good for anything.

But the senior council, the real council, ran the ship from then on. It even acted as a court and the Captain never handed out punishments again. Dad told me that the Captain reviewed everything that the council did, that he had to, to make it legal—but I never heard of him overruling their decisions.

And you know what the first thing was that that council did—after setting up meal hours and simple things like that? They decided we had to go to school!

The junior council promptly held a meeting and passed a resolution against it, but it didn't mean anything. We had school, just the same.

Peggy was on the junior council. I asked her why she didn't resign if she wasn't going to do anything. I was just teasing—as a matter of fact she put up quite a battle for us.

School wasn't so bad, though. There is very h'ttle to do in space and when you've seen one star you've seen 'em all. And the first thing we had in school was a tour of the ship, which was all right.

We went in groups of twenty and it took all day–"day" by ship's time, I mean. The Mayflower was shaped like a ball with a cone on one side—top shaped. The point of the cone was her jet—although Chief Engineer Ortega, who showed us around, called it her "torch."

If you count the torch end as her stern, then the round end, her bow, was where the control room was located; around it were the Captain's cabin and the staterooms of the officers. The torch and the whole power plant space were cut off from the rest of the ship by a radiation shield that ran right through the ship. From the shield forward to the control room was a big cargo space. It was a cylinder more than a hundred feet in diameter and was split up into holds. We were carrying all sorts of things out to the colony —earth moving machinery, concentrated soil cultures, instruments, I don't know what all.

Wrapped around this central cylinder were the decks for living, "A" deck just inside the skin of the ship, "B" deck under it, and "C" deck just inside that, with "D" deck's ceiling being the outer wall of the cargo space. "D" deck was the mess rooms and galley and recreation rooms and sick bay and such; the three outer decks were bunk rooms and staterooms. "A" deck had steps in it every ten or fifteen feet because it was fitted into the outer curve of the ship; this made the ceilings in it of various heights. The furthest forward and furthest aft on "A" deck were only about six feet between floor and ceiling and some of the smaller kids lived in them, while at the greatest width of the ship the ceilings in "A" deck must have been twelve or thirteen feet high.

From inside the ship it was hard to see how it all fitted together. Not only was it all chopped up, but the artificial gravity we had from spinning the ship made directions confusing—anywhere you stood on a deck it seemed level, but it curved sharply up behind you and in front of you. But you never came to the curved part; if you walked forward it was still level. If you walked far enough you looped the loop and came back to where you started, having walked clear around the ship.

I never would have figured it out if Mr. Ortega hadn't drawn a sketch for us.

Mr. Ortega told us that the ship was spinning three and six-tenths revolutions per minute or two hundred and sixteen complete turns an hour, which was enough to give "B" deck a centrifugal force of one-third g. "B" deck was seventy-five feet out from the axis of the Mayflower; "A" deck where I lived was further out and you weighed maybe a tenth more there, while "C" deck caught about a tenth less. "D" deck was quite a lot less and you could make yourself dizzy if you stood up suddenly in the mess room.

The control room was right on the axis; you could float in it even when the ship was spinning—or so they told me; I never was allowed inside.

Spinning the ship had another odd effect: all around us was "down." I mean to say that the only place you could put a view port was in the floor plates of "A" deck and that's where they were, four of them—big ones, each in its own compartment.

Mr. Ortega took us into one of these view galleries. The view port was a big round quartz plate in the floor, with a guard rail around it.

The first ones into the room went up to the guard rail and then backed away from it quick and two of the girls squealed. I pushed forward and got to the rail and looked down ,...nd I was staring straight into the very bottom of the universe, a million trillion miles away and all of it down.

I didn't shy away—George says I'm more acrobat than acrophobe—but I did sort of grip the railing. Nobody wants to fall that far. The quartz was surface-treated so that it didn't give off reflections and it looked as if there were nothing at all between you and Kingdom Come.

The stars were reeling across the hole from the ship spinning, which made it worse. The Big Dipper came swinging in from the left, passed almost under me, and slid away to the right—and a few seconds later it was back again. I said, "This is where I came in," and gave up my place so that someone else could have a look, but nobody seemed anxious to.

Then we went through the hydroponics plant, but there wasn't anything fancy about that—just enough plants growing to replace the oxygen we used up breathing. Eel grass, it was mostly, but there was a vegetable garden as well. I wondered how they had gotten it going before they had the passengers aboard? Mr. Ortega pointed to a CO₂ fitting in the wall. "We had to subsidize them, of course."

I guess I should have known it; it was simple arithmetic.

The Chief led us back into one of the mess rooms, we sat down, and he told us about the power plant.

He said that there had been three stages in the development of space ships: first was the chemical fuel rocket ship that wasn't very different from the big German war rockets used in the Second World War, except that they were step rockets. "You kids are too young to have seen such rockets," he said, "but they were the biggest space ships ever built. They had to be big because they were terribly inefficient. As you all know, the first rocket to reach the Moon was a four-stage rocket. Its final stage was almost as long as the Mayflower—yetits pay load was less than a ton.

"It is characteristic of space ship development that the ships have gotten smaller instead of bigger. The next development was the atom-powered rocket. It was a great improvement; steps were no longer necessary. That meant that a ship like the Daedalus could take off from Earth without even a catapult, much less step rockets, and cruise to the Moon or even to Mars. But such ships still had the shortcomings of rockets; they depended on an atomic power plant to heat up reaction mass and push it out a jet, just as their predecessors depended on chemical fuel for the same purpose.

"The latest development is the mass-conversion ship, such as the Mayflower, and it may be the final development—a mass-conversion ship is theoretically capable of approaching the speed of light. Take this trip: we accelerated at one gravity for about four hours and twenty minutes which brought us up to more than ninety miles a second. If we had held that drive for a trifle less than a year, we would approach the speed of light.
