Pollux looked at Castor. "What do you think it's worth?"

Castor's lips moved silently: "He ought to pay us to take it away." It took them another twenty minutes but they got it for three pounds of chocolate and one flat cat.

It took the better part of two weeks to make the ancient oxyalcohol engine work; another week to build a scooter rack to receive it, using tubing from Fries' second-hand supply. It was not a pretty thing, but, with the Stone's stereo gear mounted on it, it was an efficient way to get around the node. Captain Stone shook his head over it and subjected it to endless tests before he conceded that it was safe even though ugly.

In the meantime the Committee had decreed a taxi service for the doctor lady; every miner working within fifty miles of City Hall was required to take his turn at standby watch with his scooter, with a fixed payment in high grade for any run he might have to make. The Stones saw very little of Edith Stone during this time: it seemed as if every citizen of Rock City had been saving up ailments.

But they were not forced to fall back on Hazel's uninspired cooking. Fries had the Stone warped into contact with City Hall and a passenger tube sealed from the Stone's lock to an unused hatch of the bigger ship; when Dr. Stone was away they ate in his restaurant Mrs Fries was an excellent cook and she raised a great variety in her hydroponics garden.

While they were rigging the scooter the twins had time to mull over the matter of the flat cats. It had dawned on them that here in Rock City was a potential, unexploited market for flat cats. The question was: how best to milk it for all the traffic would bear?

Pol suggested that they peddle them in the scooter; he pointed out that a man's sales resistance was lowest, prac­tically zero, when he actually had a flat cat in his hands. His brother shook his head. "No good," Junior."

"Why not?"

"One, the Captain won't let us monopolize the scooter; you know he regards it as ship's equipment, built by the crew, namely us. Two, we would burn up our profits in scooter fuel. Three, it's too slow; before we could move a third of them, some idiot would have fed our first sale too much, it has kittens - and there you are, with the market flooded with flat cats. The idea is to sell them as nearly as possible all at one time."

"We could stick up a sign in the store - One-Price would let us - and sell them right out of the Stone."

" Better but not good enough. Most of these rats shop only every three or four months. No, sir, we've got to build that better mouse trap and make the world beat a path to our door."

"I've never been able to figure out why anybody would want to trap a mouse. Decompress a compartment and you kill all of them, every time."

"Just a figure of speech, no doubt Junior, what can we do to make Rock City flat-cat conscious?"

They found a way. The Belt, for all its lonely reaches - or because of them - was as neighbourly as a village. They gos­siped among themselves, by suit radio. Out in the shining blackness it was good to know that, if something went wrong, there was a man listening not five hundred miles away who would come and investigate if you broke off and did not answer.

They gossiped from node to node by their more powerful ship's radios. A rumor of death, of a big strike, or of accident, would bounce around the entire belt, relayed from rockman to rockman, at just short of the speed of light. Heartbreak node was sixty-six light minutes away, following orbit; big news often reached it in less than two hours, including numerous manual relays.

Rock City even had its own broadcast. Twice a day One-Price picked up the news from Earthside, then re-broadcast it with his own salty comments. The twins decided to follow it with one of their own, on the same wave length - a music & chatter show, with commercials. Oh, decidedly with commer­cials. They had hundreds of spools in stock which they could use, then sell, along with the portable projectors they had bought on Mars.

They started in; the show never was very good, but, on the other hand, it had no competition and it was free. Imme­diately following Fries' sign-off Castor would say, "Don't go away, neighbours! Here we are again with two hours of fun and music - and a few tips on bargains. But first, our theme - the warm and friendly purr of a Martian flat cat." Pollux would hold Fuzzy Britches up to the microphone and stroke it; the good-natured little creature would always respond with a loud buzz. "Wouldn't that be nice to come home to? And now for some music: Harry Weinstein's Sunbeam Six in "High Gravity". Let me remind you that this tape, like all other music on this program, may be purchased at an amazing saving in Flat Cat Alley, right off the City Hall - as well as Ajax three-way projectors in the Giant, Jr. model, for sound, sight, and stereo. The Sunbeam Six - hit it, Harry!"

Sometimes they would do interviews:

Castor: "A few words with one of our leading citizens, Rocks-in-his-Head Rudolf. Mr. Rudolf, all Rock City is waiting to hear from you. Tell me, do you like it out here?"

Pollux: "Naw!"

Castor: "But you're making lots of money, Mr. Rudolf?"

Pollux: "Naw!"

Castor: "At least you bring in enough high grade to eat well."

"Naw!"

"No? Tell me, why did you come out here in the first place?"

Pollux, "Bub, was you ever married?"

Sound effect of blow with blunt instrument, groan, and the unmistakable cycling of an air lock - Castor: "Sorry, folks. My assistant has just spaced Mr. Rudolf. To the purchaser of the flat cat we had been saving for Mr. Rudolf we will give away - absolutely free! - a beautiful pin-up picture printed in gorgeous living colors on fireproof paper. I hate to tell you what these pictures ordinarily sell for on Ceres; it hurts me to say how little we are letting them go for now, until our limited stock is exhausted. To the very first customer who comes in that door wanting to purchase a flat cat we will - Lock that door! Lock that door! All right, all right - all three of you will receive pin-up pictures; we don't want anyone fighting here. But you'll have to wait until we finish this broadcast Sorry, neighbours - a slight interruption but we settled it without bloodshed. But I find myself in a dilemma. I made you a promise and I did not know what would happen, but the truth is, too many customers were already here, pound­ing on the door of Flat Cat Alley. But to make good our promise I am enlarging it: not to the first customer, not to the second, nor to the third - but to the next twenty persons purchasing flat cats will go, absolutely free, one of these gor­geous pictures. Bring no money - we accept high grade or core material at the standard rates."

Sometimes they varied it by having Meade sing. She was not of concert standards, but she had a warm, intimate con­tralto. After hearing her, a man possessing not even a flat cat felt lonely indeed. She pulled even better than the slick professional recordings; the twins found it necessary to cut her in for a percentage.

But in the main they depended on the flat cats themselves. The boomers from Mars, almost to a man, bought flat cats as soon as they heard that they were available, and each became an unpaid travelling salesman for the enterprise. Hardrock men from Luna, or directly from Earth, who had never seen a flat cat, now had opportunities to see them, pet them, listen to their hypnotic purr - and were lost. The little things not only stirred to aching suppressed loneliness, but, having stimulated it, gave it an outlet.

Castor would hold Fuzzy Britches to the mike and coo, "Here is a little darling - Molly Malone. Sing for the boys, honey pet." While he stroked Fuzzy Britches Pollux would step up the power. "No, we can't let Molly go - she's a mem­ber of the family. But here is Bright Eyes. We'd like to keep Bright Eyes, too, but we mustn't be selfish. Say hello to the folks, Bright Eyes." Again he would stroke Fuzzy Britches. "Mr. P., now hand me Velvet."
