The Menace from Earth


	My name is Holly Jones and I'm fifteen. I'm very intelligent but it doesn't show, because I look like an underdone angel. Insipid.
	I was born right here in Luna City, which seems to surprise Earthside types. Actually, I'm third generation; my grandparents pioneered in Site One, where the Memorial is. I live with my parents in Artemis Apartments, the new co-op in Pressure Five, eight hundred feet down near City Hall. But I'm not there much; I'm too busy.
	Mornings I attend Tech High and afternoons I study or go flying with Jeff Hardesty -- he's my partner -- or whenever a tourist ship is in I guide groundhogs. This day the Gripsholm grounded at noon so I went straight from school to American Express.
	The first gaggle of tourists was trickling in from Quarantine but I didn't push forward as Mr. Dorcas, the manager, knows I'm the best. Guiding is just temporary (I'm really a spaceship designer), but if you're doing a job you ought to do it well.
	Mr. Dorcas spotted me. "Holly! Here, please. Miss Brentwood, Holly Jones will be your guide."
	"'Holly,'" she repeated. "What a quaint name. Are you really a guide, dear?"
	I'm tolerant of groundhogs -- some of my best friends are from Earth. As Daddy says, being born on Luna is luck, not judgment, and most people Earthside are stuck there. After all, Jesus and Gautama Buddha and Dr. Einstein were all groundhogs.
	But they can be irritating. If high school kids weren't guides, whom could they hire? "My license says so," I said briskly and looked her over the way she was looking me over.
	Her face was sort of familiar and I thought perhaps I had seen her picture in those society things you see in Earthside magazines -- one of the rich playgirls we get too many of. She was almost loathsomely lovely. . . nylon skin, soft, wavy, silverblond hair, basic specs about 35-24-34 and enough this and that to make me feel like a matchstick drawing, a low intimate voice and everything necessary to make plainer females think about pacts with the Devil. But I did not feel apprehensive; she was a groundhog and groundhogs don't count.
	"All city guides are girls," Mr. Dorcas explained. "Holly is very competent."
	"Oh, I'm sure," she answered quickly and went into tourist routine number one: surprise that a guide was needed just to find her hotel, amazement at no taxicabs, same for no porters, and raised eyebrows at the prospect of two girls walking alone through "an underground city."
	Mr. Dorcas was patient, ending with: "Miss Brentwood, Luna City is the only metropolis in the Solar System where a woman is really safe -- no dark alleys, no deserted neighborhoods, no criminal element."
	I didn't listen; I just held out my tariff card for Mr. Dorcas to stamp and picked up her bags. Guides shouldn't carry bags and most tourists are delighted to experience the fact that their thirty-pound allowance weighs only five pounds. But I wanted to get her moving.
	We were in the tunnel outside and me with a foot on the slidebelt when she stopped. "I forgot! I want a city map."
	"None available."
	"Really?"
	"There's only one. That's why you need a guide."
	"But why don't they supply them? Or would that throw you guides out of work?"
	See? "You think guiding is makework? Miss Brentwood, labor is so scarce they'd hire monkeys if they could."
	"Then why not print maps?"
	"Because Luna City isn't flat like--" I almost said, "--groundhog cities," but I caught myself.
	"--like Earthside cities," I went on. "All you saw from space was the meteor shield. Underneath it spreads out and goes down for miles in a dozen pressure zones."
	"Yes, I know, but why not a map for each level?"
	Groundhogs always say, "Yes, I know, but--"
	"I can show you the one city map. It's a stereo tank twenty feet high and even so all you see clearly are big things like the Hall of the Mountain King and hydroponics farms and the Bats' Cave."
	"'The Bats' Cave,'" she repeated. "That's where they fly, isn't it?"
	"Yes, that's where we fly."
	"Oh, I want to see it!"
	"OK. It first. . . or the city map?"
	She decided to go to her hotel first. The regular route to the Zurich is to slide up the west through Gray's Tunnel past the Martian Embassy, get off at the Mormon Temple, and take a pressure lock down to Diana Boulevard. But I know all the shortcuts; we got off at Macy-Gimbel Upper to go down their personnel hoist. I thought she would enjoy it.
	But when I told her to grab a hand grip as it dropped past her, she peered down the shaft and edged back. "You're joking."
	I was about to take her back the regular way when a neighbor of ours came down the hoist. I said, "Hello, Mrs. Greenberg," and she called back, "Hi, Holly. How are your folks?"
	Susie Greenberg is more than plump. She was hanging by one hand with young David tucked in her other arm and holding the _Daily Lunatic_, reading as she dropped. Miss Brentwood stared, bit her lip, and said, "How do I do it?"
	I said, "Oh, use both hands; I'll take the bags." I tied the handles together with my hanky and went first.
	She was shaking when we got to the bottom. "Goodness, Holly, how do you stand it? Don't you get homesick?"
	Tourist question number six . . . I said, "I've been to Earth," and let it drop. Two years ago Mother made me visit my aunt in Omaha and I was _miserable_ -- hot and cold and dirty and beset by creepy-crawlies. I weighed a ton and I ached and my aunt was always chivvying me to go outdoors and exercise when all I wanted was to crawl into a tub and be quietly wretched. And I had hay fever. Probably you've never heard of hay fever -- you don't die but you wish you could.
	I was supposed to go to a girls' boarding school but I phoned Daddy and told him I was desperate and he let me come home. What groundhogs can't understand is that they live in savagery. But groundhogs are groundhogs and loonies are loonies and never the twain shall meet.
	Like all the best hotels the Zurich is in Pressure One on the west side so that it can have a view of Earth. I helped Miss Brentwood register with the roboclerk and found her room; it had its own port. She went straight to it, began staring at Earth and going _ooh!_ and _ahh!_
	I glanced past her and saw that it was a few minutes past thirteen; sunset sliced straight down the tip of India -- early enough to snag another client. "Will that be all, Miss Brentwood?"
	Instead of answering she said in an awed voice, "Holly, isn't that the most beautiful sight you ever saw?"
	"It's nice," I agreed. The view on that side is monotonous except for Earth hanging in the sky -- but Earth is what tourists always look at even though they've just left it. Still, Earth is pretty. The changing weather is interesting if you don't have to be in it. Did you ever endure a summer in Omaha?
	"It's gorgeous," she whispered.
	"Sure," I agreed. "Do you want to go somewhere? Or will you sign my card?"
	"What? Excuse me, I was daydreaming. No, not right now -- yes, I do! Holly, I want to go out _there_! I must! Is there time? How much longer will it be light?"
	"Huh? It's two days to sunset."
	She looked startled. "How quaint. Holly, can you get us space suits? I've got to go outside."
	I didn't wince -- I'm used to tourist talk. I suppose a pressure suit looked like a space suit to them. I simply said, "We girls aren't licensed outside. But I can phone a friend."
	Jeff Hardesty is my partner in spaceship designing, so I throw business his way. Jeff is eighteen and already in Goddard Institute, but I'm pushing hard to catch up so that we can set up offices for our firm: "Jones & Hardesty, Spaceship Engineers." I'm very bright in mathematics, which is everything in space engineering, so I'll get my degree pretty fast. Meanwhile we design ships anyhow.
	I didn't tell Miss Brentwood this, as tourists think that a girl my age can't possibly be a spaceship designer.
	Jeff has arranged his class to let him guide on Tuesdays and Thursdays; he waits at West City Lock and studies between clients. I reached him on the lockmaster's phone. Jeff grinned and said, "Hi, Scale Model."
	"Hi, Penalty Weight. Free to take a client?"
	"Well, I was supposed to guide a family party, but they're late."
	"Cancel them; Miss Brentwood . . . step into pickup, please. This is Mr. Hardesty."
	Jeff's eyes widened and I felt uneasy. But it did not occur to me that Jeff could be attracted by a groundhog. . . even though it is conceded that men are robot slaves of their body chemistry in such matters. I knew she was exceptionally decorative, but it was unthinkable that Jeff could be captivated by any groundhog, no matter how well designed. They don't speak our language!
	I am not romantic about Jeff; we are simply partners. But anything that affects Jones & Hardesty affects me.
	When we joined him at West Lock he almost stepped on his tongue in a disgusting display of adolescent rut. I was ashamed of him and, for the first time, apprehensive. Why are males so childish?
	Miss Brentwood didn't seem to mind his behavior. Jeff is a big hulk; suited up for outside he looks like a Frost Giant from _Das Rheingold_; she smiled up at him and thanked him for changing his schedule. He looked even sillier and told her it was a pleasure.
	I keep my pressure suit at West Lock so that when I switch a client to Jeff he can invite me to come along for the walk. This time he hardly spoke to me after that platinum menace was in sight. But I helped her pick out a suit and took her into the dressing room and fitted it. Those rental suits take careful adjusting or they will pinch you in tender places once out in vacuum. . . besides there are things about them that one girl ought to explain to another.
	When I came out with her, not wearing my own, Jeff didn't even ask why I hadn't suited up -- he took her arm and started toward the lock. I had to butt in to get her to sign my tariff card.
	The days that followed were the longest of my life. I saw Jeff only once . . . on the slidebelt in Diana Boulevard, going the other way. She was with him.
	Though I saw him but once, I knew what was going on. He was cutting classes and three nights running he took her to the Earthview Room of the Duncan Hines. None of my business! -- I hope she had more luck teaching him to dance than I had. Jeff is a free citizen and if he wanted to make an utter fool of himself neglecting school and losing sleep over an upholstered groundhog that was his business.
	But he should not have neglected the firm's business!
	Jones & Hardesty had a tremendous backlog, because we were designing Starship _Prometheus_. This project we had been slaving over for a year, flying not more than twice a week in order to devote time to it -- and that's a sacrifice.
	Of course you can't build a starship today, because of the power plant. But Daddy thinks that there will soon be a technological break-through and mass-conversion power plants will be built -- which means starships. Daddy ought to know -- he's Luna Chief Engineer for Space Lanes and Fermi Lecturer at Goddard Institute. So Jeff and I are designing a self-supporting interstellar ship on that assumption: quarters, auxiliaries, surgery, labs -- everything.
	Daddy thinks it's just practice but Mother knows better -- Mother is a mathematical chemist for General Synthetics of Luna and is nearly as smart as I am. She realizes that Jones & Hardesty plans to be ready with a finished proposal while other designers are still floundering.
	Which was why I was furious with Jeff for wasting time over this creature. We had been working every possible chance. Jeff would show up after dinner, we would finish our homework, then get down to real work, the _Prometheus_. . . checking each other's computations, fighting bitterly over details, and having a wonderful time. But the very day I introduced him to Ariel Brentwood, he failed to appear. I had finished my lessons and was wondering whether to start or wait for him -- we were making a radical change in power plant shielding -- when his mother phoned me. "Jeff asked me to call you, dear. He's having dinner with a tourist client and can't come over."
	Mrs. Hardesty was watching me so I looked puzzled and said, "Jeff thought I was expecting him? He has his dates mixed." I don't think she believed me; she agreed too quickly.
	All that week I was slowly convinced against my will that Jones & Hardesty was being liquidated. Jeff didn't break any more dates -- how can you break a date that hasn't been made? -- but we always went flying Thursday afternoons unless one of us was guiding. He didn't call. Oh, I know where he was; he took her iceskating in Fingal's Cave.
	I stayed home and worked on the _Prometheus_, recalculating masses and moment arms for hydroponics and stores on the basis of the shielding change. But I made mistakes and twice I had to look up logarithms instead of remembering . . . I was so used to wrangling with Jeff over everything that I just couldn't function.

	Presently I looked at the name place of the sheet I was revising. "Jones & Hardesty" it read, like all the rest. I said to myself, "Holly Jones, quit bluffing; this may be The End. You know that someday Jeff would fall for somebody."
	"Of course. . . but not a _groundhog_."
	"But he _did_. What kind of an engineer are you if you can't face facts? She's beautiful and rich -- she'll get her father to give him a job Earthside. You hear me? _Earthside!_ So you look for another partner. . . or go into business on your own."
	I erased "Jones & Hardesty" and lettered "Jones & Company" and stared at it. Then I started to erase that, too -- but it smeared; I had dripped a tear on it. Which was ridiculous!
	The following Tuesday both Daddy and Mother were home for lunch which was unusual as Daddy lunches at the spaceport. Now Daddy can't even see you unless you're a spaceship but that day he picked to notice that I had dialed only a salad and hadn't finished it. "That plate is about eight hundred calories short," he said, peering at it. "You can't boost without fuel -- aren't you well?"
	"Quite well, thank you," I answered with dignity.
	"Mmm . . . now that I think back, you've been moping for several days. Maybe you need a checkup." He looked at Mother.
	"I do not either need a checkup!" I had _not_ been moping -- doesn't a woman have a right not to chatter?
	But I hate to have doctors poking at me so I added, "It happens I'm eating lightly because I'm going flying this afternoon. But if you insist, I'll order pot roast and potatoes and sleep insead!"
	"Easy, punkin'," he answered gently. "I didn't mean to intrude. Get yourself a snack when you're through . . . and say hello to Jeff for me."
	I simply answered, "OK," and asked to be excused; I was humiliated by the assumption that I couldn't fly without Mr. Jefferson Hardesty but did not wish to discuss it.
	Daddy called after me, "Don't be late for dinner," and Mother said, "Now, Jacob--" and to me, "Fly until you're tired, dear; you haven't been getting much exercise. I'll leave your dinner in the warmer. Anything you'd like?"
	"No, whatever you dial for yourself." I just wasn't interested in food, which isn't like me. As I headed for Bats' Cave I wondered if I had caught something. But my cheeks didn't feel warm and my stomach wasn't upset even if I wasn't hungry.
	Then I had a horrible thought. Could it be that I was jealous? _Me?_
	It was unthinkable. I am not romantic; I am a career woman. Jeff had been my partner and pal, and under my guidance he could have become a great spaceship designer, but our relationship was straightforward . . . a mutual respect for each other's abilities, with never any of that lovey-dovey stuff. A career woman can't afford such things -- why look at all the professional time Mother had lost over having me!
	No, I couldn't be jealous; I was simply worried sick because my partner had become involved with a groundhog. Jeff isn't bright about women and, besides, he's never been to Earth and has illusions about it. If she lured him Earthside, Jones & Hardesty was finished.
	And somehow, "Jones & Company" wasn't a substitute: the _Prometheus_ might never be built.
	I was at Bats' Cave when I reached this dismal conclusion. I didn't feel like flying but I went to the locker room and got my wings anyhow.
	Most of the stuff written about Bats' Cave gives a wrong impression. It's the air storage tank for the city, just like all the colonies have -- the place where the scavenger pumps, deep down, deliver the air until it's needed. We just happen to be lucky enough to have one big enough to fly in. But it never was built, or anything like that; it's just a big volcanic bubble, two miles across, and if it had broken through, way back when, it would have been a crater.
	Tourists sometimes pity us loonies because we have no chance to swim. Well, I tried it in Omaha and got water up my nose and scared myself silly. Water is for drinking, not playing in; I'll take flying. I've heard groundhogs say, oh yes, they had "flown" many times. But that's not _flying_. I did what they talk about, between White Sands and Omaha. I felt awful and got sick. Those things aren't safe.
	I left my shoes and skirt in the locker room and slipped my tail surfaces on my feet, then zipped into my wings and got someone to tighten the shoulder straps. My wings aren't readymade condors; they are Storer-Gulls, custom-made for my weight distribution and dimensions. I've cost Daddy a pretty penny in wings, outgrowing them so often, but these latest I bought myself with guide fees.
	They're lovely -- titanalloy struts as light and strong as bird bones, tension-compensated wrist-pinion and shoulder joints, natural action in the alula slots, and automatic flap action in stalling. The wing skeleton is dressed in styrene feather-foils with individual quilling of scapulars and primaries. They almost fly themselves.
	I folded my wings and went into the lock. While it was cycling I opened my left wing and thumbed the alula control -- I had noticed a tendency to sideslip the last time I was airborne. But the alula opened properly and I decided I must have been overcontrolling, easy to do with Storer-Gulls; they're extremely maneuverable. Then the door showed green and I folded the wing and hurried out, while glancing at the barometer. Seventeen pounds -- two more than Earth sea-level and nearly twice what we use in the city; even an ostrich could fly in that. I perked up and felt sorry for all groundhogs, tied down by six times proper weight, who never, never, never could fly.
	Not even I could, on Earth. My wing loading is less than a pound per square foot, as wings and all I weigh less than twenty pounds. Earthside that would be over a hundred pounds and I could flap forever and never get off the ground.
	I felt so good that I forgot about Jeff and his weakness. I spread my wings, ran a few steps, warped for lift and grabbed air -- lifted my feet and was airborne.
	I sculled gently and let myself glide towards the air intake at the middle of the floor -- the Baby's Ladder, we call it, because you can ride the updraft clear to the roof, half a mile above, and never move a wing. When I felt it I leaned right, spoiling with right primaries, corrected, and settled in a counterclockwise soaring glide and let it carry me toward the roof.
	A couple of hundred feet up, I looked around. The cave was almost empty, not more than two hundred in the air and half that number perched or on the ground -- room enough for didoes. So as soon as I was up five hundred feet I leaned out of the updraft and began to beat. Gliding is no effort but flying is as hard work as you care to make it. In gliding I support a mere ten pounds on each arm -- shucks, on Earth you work harder than that lying in bed. The lift that keeps you in the air doesn't take any work; you get it free from the shape of your wings just as long as there is air pouring past them.
	Even without an updraft all a level glide takes is gentle sculling with your finger tips to maintain air speed; a feeble old lady could do it. The lift comes from differential air pressures but you don't have to understand it; you just scull a little and the air supports you, as if you were lying in an utterly perfect bed. Sculling keeps you moving forward just like sculling a rowboat. . . or so I'm told; I've never been in a rowboat. I had a chance to in Nebraska but I'm not that foolhardy.
	But when you're really flying, you scull with forearms as well as hands and add power with your shoulder muscles. Instead of only the outer quills of your primaries changing pitch (as in gliding), now your primaries and secondaries clear back to the joint warp sharply on each downbeat and recovery; they no longer lift, they force you forward -- while your weight is carried by your scapulars, up under your armpits.
	So you fly faster, or climb, or both, through controlling the angle of attack with your feet -- with the tail surfaces you wear on your feet, I mean.
	Oh dear, this sounds complicated and isn't -- you just do it. You fly exactly as a bird flies. Baby birds can learn it and they aren't very bright. Anyhow, it's easy as breathing after you learn.. . and more fun than you can imagine!
	I climbed to the roof with powerful beats, increasing my angle of attack and slotting my alulae for lift without burble -- climbing at an angle that would stall most fliers. I'm little but it's all muscle and I've been flying since I was six. Once up there I glided and looked around. Down at the floor near the south wall tourists were trying glide wings -- if you call those things "wings." Along the west wall the visitors' gallery was loaded with goggling tourists. I wondered if Jeff and his Circe character were there and decided to go down and find out.
	So I went into a steep dive and swooped toward the gallery, leveled off and flew very fast along it. I didn't spot Jeff and his groundhoggess but I wasn't watching where I was going and overtook another flier, almost collided. I glimpsed him just in time to stall and drop under, and fell fifty feet before I got control. Neither of us was in danger as the gallery is two hundred feet up, but I looked silly and it was my own fault; I had violated a safety rule.
	There aren't many rules but they are necessary; the first is that orange wings always have the right of way -- they're beginners. This flier did not have orange wings but I was overtaking. The flier underneath -- or being overtaken -- or nearer to wall -- or turning counterclockwise, in that order, has the right of way.
	I felt foolish and wondered who had seen me, so I went all the way back up, made sure I had clear air, then stooped like a hawk toward the gallery, spilling wings, lifting tail, and letting myself fall like a rock.
	I completed my stoop in front of the gallery, lowering and spreading my tail so hard I could feel leg muscles knot and grabbing air with both wings, alulae slotted. I pulled level in an extremely fast glide along the gallery. I could see their eyes pop and thought smugly, "There! That'll show 'em!"
	When darn if somebody didn't stoop on me! The blast from a flier braking right over me almost knocked me out of control. I grabbed air and stopped a sideslip, used some shipyard words and looked around to see who had blitzed me. I knew the black-and-gold wing pattern -- Mary Muhlenburg, my best girl friend. She swung toward me, pivoting on a wing tip. "Hi, Holly! Scared you, didn't I?"
	"You did not! You better be careful; the flightmaster'll ground you for a month."
	"Slim chance! He's down for coffee."
	I flew away, still annoyed, and started to climb. Mary called after me, but I ignored her, thinking, "Mary my girl, I'm going to get over you and fly you right out of the air."
	That was a foolish thought as Mary flies every day and has shoulders and pectoral muscles like Mrs. Hercules. By the time she caught up with me I had cooled off and we flew side by side, still climbing. "Perch?" she called out.
	"Perch," I agreed. Mary has lovely gossip and I could use a breather. We turned toward our usual perch, a ceiling brace for flood lamps -- it isn't supposed to be a perch but the flightmaster hardly ever comes up there.
	Mary flew in ahead of me, braked and stalled dead to a perfect landing. I skidded a little but Mary stuck out a wing and steadied me. It isn't easy to come into a perch, especially when you have to approach level. Two years ago a boy who had just graduated from orange wings tried it . . . knocked off his left alula and primaries on a strut -- went fluttering and spinning down two thousand feet and crashed. He could have saved himself -- you can come in safely with a badly damaged wing if you spill air with the other and accept the steeper glide, then stall as you land. But this poor kid didn't know how; he broke his neck, dead as Icarus. I haven't used that perch since.
	We folded our wings and Mary sidled over. "Jeff is looking for you," she said with a sly grin.
	My insides jumped but I answered coolly, "So? I didn't know he was here."
	"Sure. Down there," she added, pointing with her left wing. "Spot him?"
	Jeff wears striped red and silver, but she was pointing at the tourist guide slope, a mile away. "No."
	"He's there all right." She looked at me sidewise. "But I wouldn't look him up if I were you."
	"Why not? Or for that matter, why should I?" Mary can be exasperating.
	"Huh? You always run when he whistles. But he has that Earthside siren in tow again today; you might find it embarrasing?"
	"Mary, whatever are you talking about?"
	"Huh? Don't kid me, Holly Jones; you know what I mean."
	"I'm sure I don't," I answered with cold dignity.
	"Humph! Then you're the only person in Luna City who doesn't. Everybody knows you're crazy about Jeff; everybody knows she's cut you out. . . and that you are simply simmering with jealousy."
	Mary is my dearest friend but someday I'm going to skin her for a rug. "Mary, that's preposterously ridiculous! How can you even think such a thing?"
	"Look, darling, you don't have to pretend. I'm for you." She patted my shoulders with her secondaries.
	So I pushed her over backwards. She fell a hundred feet, straightened out, circled and climbed, and came in beside me, still grinning. It gave me time to decide what to say.
	"Mary Muhlenburg, in the first place I am not crazy about anyone, least of all Jeff Hardesty. He and I are simply friends. So it's utterly nonsensical to talk about me being 'jealous.' In the second place Miss Brentwood is a lady and doesn't go around 'cutting out' anyone, least of all me. In the third place she is simply a tourist Jeff is guiding -- business, nothing more."
	"Sure, sure," Mary agreed placidly. "I was wrong. Still--" She shrugged her wings and shut up.
	"'Still' what? Mary, dont be mealy-mouthed."
	"Mmm. . . I was wondering how you knew I was talking about Ariel Brentwood -- since there isn't anything to it."
	"Why, you mentioned her name."
	"I did not."
	I thought frantically. "Uh, maybe not. But it's perfectly simple. Miss Brentwood is a client I turned over to Jeff myself, so I assumed that she must be the tourist you meant."
	"So? I don't recall even saying she was a tourist. But since she is just a tourist you two are splitting, why aren't you doing the inside guiding while Jeff sticks to outside work? I thought you guides had an agreement?"
	"Huh? If he has been guiding her inside the city, I'm not aware of it--"
	"You're the only one who isn't."
	"--and I'm not interested; that's up to the grievance committee. But Jeff wouldn't take a fee for inside guiding in any case."
	"Oh, sure! -- not one he could _bank_. Well, Holly, seeing I was wrong, why don't you give him a hand with her? She wants to learn to glide."
	Butting in on that pair was farthest from my mind. "If Mr. Hardesty wants my help, he will ask me. In the meantime I shall mind my own business . . . a practice I recommend to you!"
	"Relax, shipmate," she answered, unruffled. "I was doing you a favor."
	"Thank you, I don't need one."
	"So I'll be on my way -- got to practice for the gymkhana." She leaned forward and dropped off. But she didn't practice aerobatics; she dived straight for the tourist slope.
	I watched her out of sight, then sneaked my left hand out the hand slit and got at my hanky -- awkward when you are wearing wings but the floodlights had made my eyes water. I wiped them and blew my nose and put my hanky away and wiggled my hand back into place, then checked everything thumbs, toes, and fingers, preparatory to dropping off.
	But I didn't. I just sat there, wings drooping, and thought. I had to admit that Mary was partly right; Jeff's head was turned completely. . . over a _groundhog_. So sooner or later he would go Earthside and Jones & Hardesty was finished.
	Then I reminded myself that I had been planning to be a spaceship designer like Daddy long before Jeff and I teamed up. I wasn't dependent on anyone; I could stand alone, like Joan of Arc, or Lise Meitner.
	I felt better. . . a cold, stern pride, like Lucifer in _Paradise Lost_.
	I recognized the red and silver of Jeff's wings while he was far off and I thought about slipping quietly away. But Jeff can overtake me if he tries, so I decided, "Holly, don't be a fool! You've no reason to run. . . just be coolly polite."
	He landed by me but didn't sidle up. "Hi, Decimal Point."
	"Hi, Zero. Uh, stolen much lately?"
	"Just the City Bank but they made me put it back." He frowned and added, "Holly, are you mad at me."
	"Why, Jeff, whatever gave you such a silly notion?"
	"Uh. . . something Mary the Mouth said."
	"Her? Don't pay any attention to what she says. Half of it's always wrong and she doesn't mean the rest."
	"Yeah, a short circuit between her ears. Then you aren't mad?"
	"Of _course_ not. Why should I be?"
	"No reason I know of. I haven't been around to work on the ship for a few days.. . but I've been awfully busy."
	"Think nothing of it. I've been terribly busy myself."
	"Uh, that's fine. Look, Test Sample, do me a favor. Help me out with a friend -- a client, that is -- we'll she's a friend, too. She wants to learn to use glide wings."
	I pretended to consider it. "Anyone I know?"
	"Oh, yes. Fact is, you introduced us. Ariel Brentwood."
	"'Brentwood?' Jeff, there are so many tourists. Let me think. Tall girl? Blonde? Extremely pretty?"
	He grinned like a goof and I almost pushed him off. "That's Ariel!"
	"I recall her . . . she expected me to carry her bags. But you don't need help, Jeff. She seemed very clever. Good sense of balance."
	"Oh, yes, sure, all of that. Well, the fact is, I want you two to know each other. She's. . . well, she's just wonderful, Holly. A real person all the way through. You'll love her when you know her better. Uh... this seemed like a good chance."
	I felt dizzy. "Why, that's very thoughtful, Jeff, but I doubt if she wants to know me better. I'm just a servant she hired -- you know groundhogs."
	"But she's not at all like the ordinary groundhog. And she does want to know you better -- she _told_ me so!"
	_After you told her to think so!_ I muttered. But I had talked myself into a corner. If I had not been hampered by polite upbringing I would have said, "On your way, vacuum skull! I'm not interested in your groundhog friends" -- but what I did say was, "OK, Jeff," then gathered the fox to my bosom and dropped off into a glide.
	So I taught Ariel Brentwood to "fly." Look, those so-called wings they let tourists wear have fifty square feet of lift surface, no controls except warp in the primaries, a built-in dihedral to make them stable as a table, and a few meaningless degrees of hinging to let the wearer think that he is "flying" by waving his arms. The tail is rigid, and canted so that if you stall (almost impossible) you land on your feet. All a tourist does is run a few yards, lift up his feet (he can't avoid it) and slide down a blanket of air. Then he can tell his grandchildren how he flew, really _flew_, "just like a bird."
	An ape could learn to "fly" that much.
	I put myself to the humiliation of strapping on a set of the silly things and had Ariel watch while I swung into the Baby's Ladder and let it carry me up a hundred feet to show her that you really and truly could "fly" with them. Then I thankfully got rid of them, strapped her into a larger set, and put on my beautiful Storer-Gulls. I had chased Jeff away (two instructors is too many), but when he saw her wing up, he swooped down and landed by us.
	I looked up. "You again."
	"Hello, Ariel. Hi, Blip. Say, you've got her shoulder straps too tight."
	"Tut, tut," I said. "One coach at a time, remember? If you want to help, shuck those gaudy fins and put on some gliders then I'll use you to show how not to. Otherwise get above two hundred feet and stay there; we don't need any dining lounge pilots."
	Jeff pouted like a brat but Ariel backed me up. "Do what teacher says, Jeff. That's a good boy."
	He wouldn't put on gliders but he didn't stay clear, either. He circled around us, watching, and got bawled out by the flightmaster for cluttering the tourist area.
	I admit Ariel was a good pupil. She didn't even get sore when I suggested that she was rather mature across the hips to balance well; she just said that she had noticed that I had the slimmest behind around there and she envied me. So I quit trying to get her goat, and found myself almost liking her as long as I kept my mind firmly on teaching. She tried hard and learned fast -- good reflexes and (despite my dirty crack) good balance. I remarked on it and she admitted diffidently that she had had ballet training.
	About mid-afternoon she said, "Could I possibly try real wings?"
	"Huh? Gee, Ariel, I don't think so."
	"Why not?"
	There she had me. She had already done all that could be done with those atrocious gliders. If she was to learn more, she had to have real wings. "Ariel, it's dangerous. It's not what you've been doing, believe me. You might get hurt, even killed."
	"Would you be held responsible?"
	"No. You signed a release when you came in."
	"Then I'd like to try it."
	I bit my lip. If she had cracked up without my help, I wouldn't have shed a tear -- but to let her do something too dangerous while she was my pupil. . . well, it smacked of David and Uriah. "Ariel, I can't stop you . . . but I should put my wings away and not have anything to do with it."
	It was her turn to bite her lip. "If you feel that way, I can't ask you to coach me. But I still want to. Perhaps Jeff will help me."
	"He probably will," I blurted out, "if he is as big a fool as I think he is!"
	Her company face slipped but she didn't say anything because just then Jeff stalled in beside us. "What's the discussion?"
	We both tried to tell him and confused him for he got the idea I had suggested it, and started bawling me out. Was I crazy? Was I trying to get Ariel hurt? Didn't I have any sense?
	"_Shut up!_" I yelled, then added quietly but firmly, "Jefferson Hardesty, you wanted me to teach your girl friend, so I agreed. But don't butt in and don't think you can get away with talking to me like that. Now beat it! Take wing. Grab air!"
	He swelled up and said slowly, "I absolutely forbid it."
	Silence for five long counts. Then Ariel said quietly, "Come, Holly. Let's get me some wings."
	"Right, Ariel."
	But they don't rent real wings. Fliers have their own; they have to. However, there are second-hand ones for sale because kids outgrow them, or people shift to custom-made ones, or something. I found Mr. Schultz who keeps the key, and said that Ariel was thinking of buying but I wouldn't let her without a tryout. After picking over forty-odd pairs I found a set which Johnny Queveras had outgrown but which I knew were all right. Nevertheless I inspected them carefully. I could hardly reach the finger controls but they fitted Ariel.
	While I was helping her into the tail surfaces I said, "Ariel? This is still a bad idea."
	"I know. But we can't let men think they own us."
	"I suppose not."
	"They do own us, of course. But we shouldn't let them know it." She was feeling out the tail controls. "The big toes spread them?"
	"Yes. But don't do it. Just keep your feet together and toes pointed. Look, Ariel, you really aren't ready. Today all you will do is glide, just as you've been doing. Promise?"
	She looked me in the eye. "I'll do exactly what you say. not even take wing unless you OK it."
	"OK. Ready?"
	"I'm ready."
	"All right. Wups! I goofed. They aren't orange."
	"Does it matter?"
	"It sure does." There followed a weary argument because Mr. Schultz didn't want to spray them orange for a tryout. Ariel settled it by buying them, then we had to wait a bit while the solvent dried.
	We went back to the tourist slope and I let her glide, cautioning her to hold both alulae open with her thumbs for more lift at slow speeds, while barely sculling with her fingers. She did fine, and stumbled in landing only once. Jeff stuck around, cutting figure eights above us, but we ignored him. Presently I taught her to turn in a wide, gentle bank -- you can turn those awful glider things but it takes skill; they're only meant for straight glide.
	Finally I landed by her and said, "Had enough?"
	"I'll never have enough! But I'll unwing if you say."
	"Tired?"
	"No." She glanced over her wing at the Baby's Ladder; a dozen fliers were going up it, wings motionless, soaring lazily. "I wish I could do that just once. It must be heaven."
	I chewed it over. "Actually, the higher you are, the safer you are."
	"Then why not?"
	"Mmm . . . safer _provided_ you know what you're doing. Going up that draft is just gliding like you've been doing. You lie still and let it lift you half a mile high. Then you come down the same way, circling the wall in a gentle glide. But you're going to be tempted to do something you don't understand yet -- flap your wings, or cut some caper."
	She shook her head solemnly. "I won't do anything you haven't taught me."
	I was still worried. "Look, it's only half a mile up but you cover five miles going there and more getting down. Half an hour at least. Will your arms take it?"
	"I'm sure they will."
	"Well. . . you can start down anytime; you don't have to go all the way. Flex your arms a little now and then, so they won't cramp. Just don't flap your wings."
	"I won't."
	"OK." I spread my wings. "Follow me."
	I led her into the updraft, leaned gently right, then back left to start the counterclockwise climb, all the while sculling very slowly so that she could keep up. Once we were in the groove I called out, "Steady as you are!" and cut out suddenly, climbed and took station thirty feet over and behind her. "Ariel?"
	"Yes, Holly?"
	"I'll stay over you. Don't crane your neck; you don't have to watch me, I have to watch you. You're doing fine."
	"I feel fine!"
	"Wiggle a little. Don't stiffen up. It's a long way to the roof. You can scull harder if you want to."
	"Aye aye, Cap'n!"
	"Not tired?"
	"Heavens, no! Girl, I'm living!" She giggled. "And mama said I'd never be an angel!"
	I didn't answer because red-and-silver wings came charging at me, braked suddenly and settled into the circle between me and Ariel. Jeff's face was almost as red as his wings. "What the devil do you think you are doing?"
	"Orange wings!" I yelled. "Keep clear!"
	"Get down out of here! Both of you!"
	"Get out from between me and my pupil. You know the rules."
	"Ariel!" Jeff shouted. "Lean out of the circle and glide down. I'll stay with you."
	"Jeff Hardesty," I said savagely, "I give you three seconds to get out from between us -- then I'm going to report you for violation of Rule One. For the third time -- Orange Wings!"
	Jeff growled something, dipped his right wing and dropped out of formation. The idiot sideslipped within five feet of Ariel's wing tip. I should have reported him for that; all the room you can give a beginner is none too much.
	I said, "OK, Ariel?"
	"OK, Holly. I'm sorry Jeff is angry."
	"He'll get over it. Tell me if you feel tired."
	"I'm not. I want to go all the way up. How high are we?"
	"Four hundred feet, maybe."
	Jeff flew below us a while, then climbed and flew over us. . . probably for the same reason I did: to see better. It suited me to have two of us watching her as long as he didn't interfere; I was beginning to fret that Ariel might not realize that the way down was going to be as long and tiring as the way up. I was hoping she would cry uncle. I knew I could glide until forced down by starvation. But a beginner gets tense.
	Jeff stayed generally over us, sweeping back and forth -- he's too active to glide very long -- while Ariel and I continued to soar, winding slowly up toward the roof. It finally occurred to me when we were about halfway up that I could cry uncle myself; I didn't have to wait for Ariel to weaken. So I called out, "Ariel? Tired now?"
	"No."
	"Well, I am. Could we go down, please?"
	She didn't argue, she just said, "All right. What am I to do?"
	"Lean right and get out of the circle." I intended to have her move out five or six hundred feet, get into the return down draft, and circle the cave down instead of up. I glanced up, looking for Jeff. I finally spotted him some distance away and much higher but coming toward us. I called out, "Jeff! See you on the ground." He might not have heard me but he would see if he didn't hear; I glanced back at Ariel.
	I couldn't find her.
	Then I saw her, a hundred feet below -- flailing her wings and falling, out of control.
	I didn't know how it happened. Maybe she leaned too far, went into a sideslip and started to struggle. But I didn't try to figure it out; I was simply filled with horror. I seemed to hang there frozen for an hour while I watched her.
	But the fact appears to be that I screamed "Jeff!" and broke into a stoop.
	But I didn't seem to fall, couldn't overtake her. I spilled my wings completely -- but couldn't manage to fall; she was as far away as ever.
	You do start slowly, of course; our low gravity is the only thing that makes human flying possible. Even a stone falls a scant three feet in the first second. But the first second seemed endless.
	Then I knew I was falling. I could feel rushing air -- but I still didn't seem to close on her. Her struggles must have slowed her somewhat, while I was in an intentional stoop, wings spilled and raised over my head, falling as fast as possible. I had a wild notion that if I could pull even with her, I could shout sense into her head, get her to dive, then straighten out in a glide. But I couldn't _reach_ her.
	This nightmare dragged on for hours.
	Actually we didn't have room to fall for more than twenty seconds; that's all it takes to stoop a thousand feet. But twenty seconds can be horribly long . . . long enough to regret every foolish thing I had ever done or said, long enough to say a prayer for us both.. . and to say good-bye to Jeff in my heart. Long enough to see the floor rushing toward us and know that we were both going to crash if I didn't overtake her mighty quick.
	I glanced up and Jeff was stooping right over us but a long way up. I looked down at once.. . and I was overtaking her... I was passing her -- _I was under her!_
	Then I was braking with everything I had, almost pulling my wings off. I grabbed air, held it, and started to beat without ever going to level flight. I beat once, twice, three times. . . and hit her from below, jarring us both.
	Then the floor hit us.

	I felt feeble and dreamily contented. I was on my back in a dim room. I think Mother was with me and I know Daddy was. My nose itched and I tried to scratch it, but my arms wouldn't work. I fell asleep again.
	I woke up hungry and wide awake. I was in a hospital bed and my arms still wouldn't work, which wasn't surprising as they were both in casts. A nurse came in with a tray. "Hungry?" she asked.
	"Starved," I admitted.
	"We'll fix that." She started feeding me like a baby.
	I dodged the third spoonful and demanded, "What happened to my arms?"
	"Hush," she said and gagged me with a spoon.
	But a nice doctor came in later and answered my question. "Nothing much. Three simple fractures. At your age you'll heal in no time. But we like your company so I'm holding you for observation of possible internal injury."
	"I'm not hurt inside," I told him. "At least, I don't hurt."
	"I told you it was just an excuse."
	"Uh, Doctor?"
	"Well?"
	"Will I be able to fly again?" I waited, scared.
	"Certainly. I've seen men hurt worse get up and go three rounds."
	"Oh. Well, thanks. Doctor? What happened to the other girl? Is she. . . did she...?"
	"Brentwood? She's here."
	"She's right here," Ariel agreed from the door. "May I come in?"
	My jaw dropped, then I said, "Yeah. Sure. Come in."
	The doctor said, "Don't stay long," and left. I said, "Well, sit down."
	"Thanks." She hopped instead of walked and I saw that one foot was bandaged. She got on the end of the bed.
	"You hurt your foot."
	She shrugged. "Nothing. A sprain and a torn ligament. Two cracked ribs. But I would have been dead. You know why I'm not?"
	I didn't answer. She touched one of my casts. "That's why. You broke my fall and I landed on top of you. You saved my life and I broke both your arms."
	"You don't have to thank me. I would have done it for anybody."
	"I believe you and I wasn't thanking you. You can't thank a person for saving your life. I just wanted to make sure you knew that I knew it."
	I didn't have an answer so I said, "Where's Jeff? Is he all right?"
	"He'll be along soon. Jeff's not hurt . . . though I'm surprised he didn't break both ankles. He stalled in beside us so hard that he should have. But Holly . . . Holly my very dear . . . I slipped in so that you and I could talk about him before he got here."
	I changed the subject quickly. Whatever they had given me made me feel dreamy and good, but not beyond being embarrassed. "Ariel, what happened? You were getting along fine -- then suddenly you were in trouble."
	She looked sheepish. "My own fault. You said we were going down, so I looked down. Really looked, I mean. Before that, all my thoughts had been about climbing to the roof; I hadn't thought about how far down the floor was. Then I looked down and got dizzy and panicky and went all to pieces." She shrugged. "You were right. I wasn't ready."
	I thought about it and nodded. "I see. But don't worry -- when my arms are well, I'll take you up again."
	She touched my foot. "Dear Holly. But I won't be flying again; I'm going back where I belong."
	"Earthside?"
	"Yes. I'm taking the _Billy Mitchell_ on Wednesday."
	"Oh. I'm sorry."
	She frowned slightly. "Are you? Holly, you don't like me, do you?"
	I was startled silly. What can you say? Especially when it's true? "Well," I said slowly, "I don't dislike you. I just don't know you very well."
	She nodded. "And I don't know you very well . . . even though I got to know you a lot better in a very few seconds. But Holly listen please and don't get angry. It's about Jeff. He hasn't treated you very well the last few days -- while I've been here, I mean. But don't be angry with him. I'm leaving and everything will be the same."
	That ripped it open and I couldn't ignore it, because if I did, she would assume all sorts of things that weren't so. So I had to explain. . . about me being a career woman.. . how, if I had seemed upset, it was simply distress at breaking up the firm of Jones & Hardesty before it even finished its first starship . how I was not in love with Jeff but simply valued him as a friend and associate. . . but if Jones & Hardesty couldn't carry on, then Jones & Company would. "So you see, Ariel, it isn't necessary for you to give up Jeff. If you feel you owe me something, just forget it. It isn't necessary."
	She blinked and I saw with amazement that she was holding back tears. "Holly, Holly. . . you don't understand at all."
	"I understand all right. I'm not a child."
	"No, you're a grown woman. . . but you haven't found it out." She held up a finger. "One -- Jeff doesn't love me."
	"I don't believe it."
	"Two. . . I don't love him."
	"I don't believe that, either."
	"Three . . . you say you don't love him -- but we'll take that up when we come to it. Holly, am I beautiful?"
	Changing the subject is a female trait but I'll never learn to do it that fast. "Huh?"
	"I said, 'Am I beautiful?'"
	"You know darn well you are!"
	"Yes. I can sing a bit and dance, but I would get few parts if I were not, because I'm no better than a third-rate actress. So I have to be beautiful. How old am I?"
	I managed not to boggle. "Huh? Older than Jeff thinks you are. Twenty-one, at least. Maybe twenty-two."
	She sighed. "Holly, I'm old enough to be your mother."
	"Huh? I don't believe that, either."
	"I'm glad it doesn't show. But that's why, though Jeff is a dear, there never was a chance that I could fall in love with him. But how I feel about him doesn't matter; the important thing is that he loves you."
	"What? That's the silliest thing you've said yet! Oh, he likes me -- or did. But that's all." I gulped. "And it's all I want. Why, you should hear the way he talks to me."
	"I have. But boys that age can’t say what they mean; they get embarrassed."
	"But--"
	"Wait, Holly. I saw something you didn't because you were knocked cold. When you and I bumped, do you know what happened?"
	"Uh, no."
	"Jeff arrived like an avenging angel, a split second behind us. He was ripping his wings off as he hit, getting his arms free. He didn't even look at me. He just stepped across me and picked you up and cradled you in his arms, all the while bawling his eyes out."
	"He did?"
	"He did."
	I mulled it over. Maybe the big lunk did kind of like me, after all.
	Ariel went on, "So you see, Holly, even if you don't love him, you must be very gentle with him, because he loves you and you can hurt him terribly."
	I tried to think. Romance was still something that a career woman should shun . . . but if Jeff really did feel that way -- well. . . would it be compromising my ideals to marry him just to keep him happy? To keep the firm together? Eventually, that is?
	But if I did, it wouldn't be Jones & Hardesty; it would be Hardesty & Hardesty.
	Ariel was still talking: "--you might even fall in love with him. It does happen, hon, and if it did, you'd be sorry if you had chased him away. Some other girl would grab him; he's awfully nice."
	"But," I shut up for I heard Jeff's step -- I can always tell it. He stopped in the door and looked at us, frowning.
	"Hi, Ariel."
	"Hi, Jeff."
	"Hi, Fraction." He looked me over. "My, but you're a mess."
	"You aren't pretty yourself. I hear you have flat feet."
	"Permanently. How do you brush your teeth with those things on your arms?"
	"I don't."
	Ariel slid off the bed, balanced on one foot. "Must run. See you later, kids."
	"So long, Ariel."
	"Good-bye, Ariel. Uh. . . thanks."
	Jeff closed the door after she hopped away, came to the bed and said gruffly, "Hold still."
	Then he put his arms around me and kissed me.
	Well, I couldn't stop him, could I? With both arms broken? Besides, it was consonant with the new policy of the firm. I was startled speechless because Jeff never kisses me, except birthday kisses, which don't count. But I tried to kiss back and show that I appreciated it.
	I don't know what the stuff was they had been giving me but my ears began to ring and I felt dizzy again.
	Then he was leaning over me. "Runt," he said mournfully, "you sure give me a lot of grief."
	"You're no bargain yourself, flathead," I answered with dignity.
	"I suppose not." He looked me over sadly. "What are you crying for?"
	I didn't know that I had been. Then I remembered why. "Oh, Jeff -- I busted my pretty wings!"
	"We'll get you more. Uh, brace yourself. I'm going to do it again."
	"All right." He did.
	I suppose Hardesty & Hardesty has more rhythm than Jones & Hardesty.
	It really sounds better.
