"How?"

"Doctor, this is outside my specialty. But everybody knows that your best ships use hydrogen as reaction mass heated by a fusion reactor. But hydrogen is expensive in Luna and any mass could be reaction mass; it just would not be as efficient. Can you visualize an enormous, brute-force space tug designed to fit Lunar conditions? It would use raw rock, vaporized, as reaction mass and would be designed to go up into parking orbit, pick up those shipments from Terra, bring them down to Luna's surface. It would be ugly, all the fancies stripped away--might not be manned even by a Cyborg. It can be piloted from the ground, by computer."

"Yes, I suppose such a ship could be designed. But let's not complicate things. Have you covered the essentials about this catapult?"

"I believe so, Doctor. The site is the crucial thing. Take that peak Nanda Devi. By the maps I have seen it appears to have a long, very high ridge sloping to the west for about the length of our catapult. If that is true, it would be ideal--less to cut away, less to bridge. I don't mean that it is the ideal site but that is the sort to look for: a very high peak with a long, long ridge west of it."

"I understand." Dr. Chan left abruptly.

Next few weeks I repeated that in a dozen countries, always in private and with implication that it was secret. All that changed was name of mountain. In Ecuador I pointed out that Chimborazo was almost on equator--ideal! But in Argentina I emphasized that their Aconcagua was highest peak in Western Hemisphere. In Bolivia I noted that Altoplano was as high as Tibetan Plateau (almost true), much nearer equator, and offered a wide choice of sites for easy construction leading up to peaks comparable to any on Terra.

I talked to a North American who was a political opponent of that choom who had called us "rabble." I pointed out that, while Mount McKinley was comparable to anything in Asia or South America, there was much to be said for Mauna Loa--extreme ease of construction. Doubling gees to make it short enough to fit, and Hawaii would be Spaceport of World... whole world, for we talked about day when Mars would be exploited and freight for three (possibly four) planets would channel through their "Big Island."

Never mentioned Mauna Loa's volcanic nature; instead I noted that location permitted an aborted load to splash harmlessly in Pacific Ocean.

In Sovunion was only one peak discussed--Lenin, over thousand meters (and rather too close to their big neighbor).

Kilimanjaro, Popocatepetl, Logan, El Libertado--my favorite peak changed by country; all that we required was that it be "highest mountain" in hearts of locals. I found something to say about modest mountains of Chad when we were entertained there and rationalized so well I almost believed it.

Other times, with help of leading questions from Stu LaJoie's stooges, I talked about chemical engineering (of which I know nothing but had memorized facts) on surface of Luna, where endless free vacuum and sunpower and limitless raw materials and predictable conditions permitted ways of processing expensive or impossible Earthside--when day arrived that cheap shipping both ways made it profitable to exploit Luna's virgin resources, Was always a suggestion that entrenched bureaucracy of Lunar Authority had failed to see great potential of Luna (true), plus answer to a question always asked, which answer asserted that Luna could accept any number of colonists.

This also was true, although never mentioned that Luna (yes, and sometimes Luna's Loonies) killed about half of new chums. But people we talked to rarely thought of emigrating themselves; they thought of forcing or persuading others to emigrate to relieve crowding--and to reduce their own taxes. Kept mouth shut about fact that half-fed swarms we saw everywhere did breed faster than even catapulting could offset.

We could not house, feed, and train even a million new chums each year--and a million wasn't a drop on Terra; more babies than that were conceived every night. We could accept far more than would emigrate voluntarily but if they used forced emigration and flooded us... Luna has only one way to deal with a new chum: Either he makes not one fatal mistake, in personal behavior or in coping with environment that will bite without warning... or he winds up as fertilizer in tunnel farm.

All that immigration in huge numbers could mean would be that a larger percentage of immigrants would die--too few of us to help them past natural hazards.

However, Prof did most talking about "Luna's great future." I talked about catapults.

During weeks we waited for committee to recall us, we covered much ground. Stu's men had things set up and only question was how much we could take. Would guess that every week on Terra chopped a year off our lives, maybe more for Prof. But he never complained and was always ready to be charming at one more reception.

We spent extra time in North America. Date of our Declaration of Independence, exactly three hundred years after that of North American British colonies, turned out to be wizard propaganda and Stu's manipulators made most of it. North Americans are sentimental about their "United States" even though it ceased to mean anything once their continent had been rationalized by F.N. They elect a president every eight years, why, could not say--why do British still have Queen?--and boast of being "sovereign." "Sovereign," like "love," means anything you want it to mean; it's a word in dictionary between "sober" and "sozzled."

"Sovereignty" meant much in North America and "Fourth of July" was a magic date; Fourth-of-July League handled our appearances and Stu told us that it had not cost much to get it moving and nothing to keep going; League even raised money used elsewhere--North Americans enjoy giving no matter who gets it.

Farther south Stu used another date; his people planted idea that coup d'etat had been 5 May instead of two weeks later. We were greeted with "Cinco de Mayo! Libertad! Cinco de Mayo!" I thought they were saying, "Thank you"-- Prof did all talking.

But in 4th-of-July country I did better. Stu had me quit wearing a left arm in public, sleeves of my costumes were sewed up so that stump could not be missed, and word was passed that I had lost it "fighting for freedom." Whenever I was asked about it, all I did was smile and say, "See what comes of biting nails?"--then change subject.

I never liked North America, even first trip. It is not most crowded part of Terra, has a mere billion people. In Bombay they sprawl on pavements; in Great New York they pack them vertically--not sure anyone sleeps. Was glad to be in invalid's chair.

Is mixed-up place another way; they care about skin color--by making point of how they don't care. First trip I was always too light or too dark, and somehow blamed either way, or was always being expected to take stand on things I have no opinions on. Bog knows I don't know what genes I have. One grandmother came from a part of Asia where invaders passed as regularly as locusts, raping as they went--why not ask her?

Learned to handle it by my second makee-learnee but it left a sour taste. Think I prefer a place as openly racist as India, where if you aren't Hindu, you're nobody--except that Parsees look down on Hindus and vice versa. However I never really had to cope with North America's reverse-racism when being "Colonel O'Kelly Davis, Hero of Lunar Freedom."

We had swarms of bleeding hearts around us, anxious to help. I let them do two things for me, things I had never had time, money, or energy for as a student: I saw Yankees play and i visited Salem.

Should have kept my illusions. Baseball is better over video, you can really see it and aren't pushed in by two hundred thousand other people. Besides, somebody should have shot that outfield. I spent most of that game dreading moment when they would have to get my chair out through crowd--that and assuring host that I was having a wonderful time.
