One thing about Di, which makes men adore her, is that she contrives to seem exquisitely sympathetic and enthusiastic without ever gushing. It's partly the shape of her eyes and the shortness of her upper lip, which combine together to give a lovely, rapt, brooding expression, that saves her the trouble of thinking up adjectives. With this look on, she appeals to all the love of romance and adventure in their hearts, I'm sure. They would do anything to win it for themselves. I would myself if I were a man, and didn't know her; so when Captain March took us into his hangar, and she turned on the look, I didn't blame him for forgetting the very existence of his small pal. It only made me sad.

"I thought I'd better take the _Golden Eagle_ up for a short run, and test her before you came, to see that she was all right," he was still apologizing. "Then she behaved so well, I got going, and stayed up longer than I meant. But I saw the car stop, so I hurried down."

"I should think you did 'hurry down!'" laughed Diana. "The way you aimed at your hangar from far up in the sky, and shot in, was like a marksman aiming at the bull's-eye on a target, and getting it. What do you call 'testing' your monoplane? What had you been doing to make all those people applaud?"

"Oh, only a little upside-down flying," said Captain March, as he might have said "only a little breathing exercise." "You see, I make stability tests. That's what I'm _for_. And with my appliances, being upside down's no more to me than it is to a fly when he walks on the ceiling."

Di's eyes said, "You hero! you splendid, modest hero!"--said it so plainly that the hero faintly blushed, though it was hard to trace a blush on his face, burnt red-brown by sun and wind. My eyes said nothing at all, but if they had recited a whole page of Shakespeare's sonnets he would have been none the wiser.

He led us into the hangar, where two fascinatingly smudged mechanics were in attendance on the magic bird; and he remembered to be nice and respectful to Father. Explanations of the mechanism were ostensibly addressed to our parent, but in reality all the eloquence was for Di, whose eyes poured forth appreciative intelligence as stars pour forth rays. Captain March couldn't be expected to know, poor fellow, that Di, if obliged to choose between two deadly dull evils, would rather hear a cook tell how to boil potatoes than listen to any mechanical talk.

However, it wasn't really needful to listen, if one's eyes were well trained; and Di was having the "time of her life" in meeting an airman.

Even I could see that this monoplane, fitted with Captain March's inventions, was a different looking creature from the other bird machines which were shooting up into the air, or darting back into their dens, all around us. The _Golden Eagle's_ quiet, graceful wings, instead of being in a straight line with each other, were set at an obtuse angle one from another; and on the end of each were odd little extra triangular tips, hinged to the main wings. I longed to pour out questions, for the "why" of things, especially mechanical things, has interested me ever since I was old enough to pick a doll to pieces, to see what made its eyes open and shut. But Di was asking idiotic questions in the sweetest way, and Captain March was laughing and delighted. It pleased him a great deal more that she should want to know precisely why he had named his monoplane the _Golden Eagle_ than if Father or I had catechized him with the trained intelligence of a scientist.

"I've been unoriginal enough, I'm afraid, to name my big baby after myself," he said, "my nickname being Eagle. The golden eagle, you know, is our national bird."

"So her hangar is 'The Eagle's Nest,'" said Di. "That's awfully nice.

But why not name her instead the _Winged Victory_?"

"Wouldn't it be rather conceited?"

"Not after what she's already done, and shown that she can do. It's conceited of me to suggest it, though, for--for the _Winged Victory_ is a sort of a nickname of _mine_ since a fancy dress ball at the beginning of the season."

"It suits you exactly," said Captain March. "If Lord Ballyconal will let you be my first lady pa.s.senger, and if, after she's given you a run, you think her worthy, she shall be renamed the _Winged Victory_, provided you'll baptize her."

"Oh, Bally, dear, you will let me go, won't you?" Di pleaded, using her pet name for Father, which he likes because it sounds young and unparental. Then catching a bleak gleam in my eyes, she hastily added: "And afterward Peggy, if Captain March will take her up."

Father hesitated, but the newspapers and people at the Emba.s.sy ball who knew all about Eagle March had spoken so highly of the machine, that it seemed an insult to a famous airman's skill to refuse. The two mechanics wheeled the monoplane out of the shed, and Captain March explained how easy and safe he could make things for a pa.s.senger. Lots of men had been up with him, but he had never asked a woman. "Only a short flight, I'll take her," he almost pleaded. "I can give her a helmet. Perhaps you'd rather go first yourself, though, and see what it's like."

Father may not have had a particularly good time on earth, but anyhow, he preferred it to atmospheric effects. He said that he had no head for heights, but if Di and Peggy wanted to go, and Captain March was kind enough to take them--er--up, a tiny way into the--er--air, he supposed that in these days he ought not to offer any objections.

Captain March had the spare helmet ready (it looked so new and smart, I felt sure he had bought it for the occasion), and nothing stood between Diana the Huntress and her quarry--nothing except her own changing mood.

I think it was the look of the helmet which gave her that sinking feeling of irrevocability which seems to sever you, as with a sword, from all the dear little safe things that have made up your life in the past. She glanced from the helmet which the airman held toward her to the monoplane spread-eagling on the ground. I saw her big eyes dilate as they fixed themselves anxiously on the pa.s.senger's perch, to which the honoured guest must climb, above the conductor's seat, crawling through the wire stays, or whatever you call them, which were like a spider's web inviting a fly. Diana turned pale. Even her lips were white. The shadows under her eyes darkened as if she were ill.

"You're--you're sure it's safe?" she faltered.

"Safe as a house. Safer than a _jerry_-built house," Captain March a.s.sured her cheeringly. "Look at these!" and he pointed out again all the features of his invention that made the automatic stability of the machine. "But if you----"

"Oh! I'm not afraid," quavered Di, her eyes roving in an agonized way over the crowd collecting to see the lovely girl taken up into the sky by the brave airman. "It isn't that. Only--it won't make me seasick, will it?"

"I've never had a pa.s.senger seasick," said Eagle.

"And--you won't turn upside down, will you?"

"Of course not!"

"Well, then, I--I'll go."

On with the condemned cap!--I mean the leather helmet. Diana's paling beauty was blotted out. Wrapped in her fur-lined cloak, she was trembling all over. Her hands, which she held confidingly out for the thick mittens Captain March had got for her, shook like the last leaves on a frozen tree.

"Think you're fit for it, Di?" Father asked anxiously.

"Yes, indeed!" came hissing through the helmet. But I felt it was only the tonic of other women's envy which was keeping her up. I was envying her, too.

Captain March helped Di scramble into her perch. His hand was steady and strong. All his life and skill and manhood were for her. She was tenderly yet firmly strapped into place, and told how she was to hold on, and not to be afraid. There would be some noise, but she mustn't mind; and there was the little apparatus Captain March had invented, by which a pa.s.senger could communicate with the conductor. It was something like the bulb you squeeze in a motor car when you want the chauffeur to turn right or left or stop.

"Press once if you're sick of it, and want to come down," said Eagle.

"Twice if you want to go higher. There's a whistle close to my ear, so sharp it cuts through the motor noise."

My heart beat almost as fast as if I were in the monoplane myself when Eagle was ready to start, looking like a twentieth-century, leather-masked Apollo starting out to drive his sun chariot up to the zenith and down the other side. The motor purred, and the propeller began to revolve. Diana, tense as a stretched violin string, was hanging on already, like grim death. The two mechanics held the tail of the impatient giant bird, and when Eagle raised one hand, they let go. For perhaps fifty yards the _Golden Eagle_ ran lightly over the turf on her bicycle wheels; then her master tilted the planes, and his namesake soared upward from the ground into the air.

As she went, through the noise she made I heard a shriek from the pa.s.senger. Diana's pride, which denied cowardice in the joy of being envied, was forgotten in the primitive emotion of fear. What my sister did I could not see, as the monoplane mounted so quickly; but almost at once I realized that she must have signalled her wish to descend, for the _Eagle_ ceased to soar, dropped, and began gently gliding down. A moment later the great winged form was landing once more close to its own shed.

Father rushed to the rescue of his darling, and Captain March--out of his seat in a second--was unfastening the straps and anxiously extricating Diana from the pa.s.senger's perch. I couldn't help feeling ashamed before all the people--scornful or sympathetic, who were looking on--that my sister had shown herself a coward; but I was sorry for her, too. She had quite collapsed, and lay in Father's arms as Captain March unfastened her helmet. I wasn't mean enough to think of rejoicing because, in taking my place away, she had been tried and found wanting.

Instead, I found myself really afraid that Captain March might despise the poor girl for the timidity which humiliated him as well as her. But I need not have worried. Pulling off the helmet in that clumsy way a man has with any sort of headgear, the wheel of braided hair Diana wore, wound over each ear in the Eastern fashion that came from "Kismet," was loosened, and a thick plait with an engaging wave at the end fell down on either side of her face. Standing, but supported in Father's arms, her head lay on his shoulder, her eyes closed, long curling lashes resting on marble cheeks. I had never seen her half so beautiful, and Captain March gazed at her as if he would gladly give his life for a rea.s.suring smile.

"Shall I fetch a doctor?" he asked miserably. "There's sure to be one, somewhere around."

Before Father could answer, Di opened her eyes, and Captain March got the smile without paying the price.

"I--I'm all right," she breathed. "So sorry! I wasn't afraid, you know.

It was my _heart_. It seemed to stop."

"Of course you weren't afraid," Eagle encouraged her. "I can never forgive myself for making you suffer."

Diana's smile graciously forgave the brutal fellow for his blundering, and she extricated herself from Father's arms, the colour slowly stealing back to her lips and cheeks. She shook her head a little, and the two braids, stuck full of tiny tortoise-sh.e.l.l hairpins, tumbled over her breast. Captain March nearly ate her up with his eyes, and then, through their windows, his soul might be seen worshipping, and begging the G.o.ddess's pardon on its knees.

"She's not strong," Father apologized. "It's my fault for letting her go up; I ought to have remembered her heart."

It's a great a.s.set, a weak heart, for a person who has just made an exhibition of cowardice. Like charity, it covers a mult.i.tude of sins.

I'd never before heard of Di's heart being weak; and at home, if there were a ball anywhere within twenty miles, she could always dance at it till morning. However, I was glad she'd thought of her heart in time, and saved the situation. It was an accommodating heart, for it came up smiling, when the petting Di got had satisfied her that she wasn't to be blamed for the fiasco.

"I think flying must be a wonderful experience for any one whose heart is quite right," she consoled Captain March. "It's a pity, for the credit of the family, you didn't take Peggy up first."

"I suppose she won't feel like going, after what has happened to you?"

said he, remembering my existence.

"Oh, I do feel like it, more than ever," I exclaimed, "that is, if you don't mind risking another of us."

"I don't think we'd better trouble Captain March again," Father cut in.

"He wouldn't like a second failure."

"He won't have one," I said. "My heart is as strong as a Gnome motor. Do let me go. It will give Di time to rest."

Whether that argument decided Father, or whether he really did hope I might reestablish the family credit for courage, I don't know; anyway, he made no further objections. The fur-lined cloak, helmet, and mittens were handed over to me. I crawled through the spider's web to the tiny throne vacated by its late queen, and was strapped in as Di had been.

Not one qualm did I feel as I looked down over Eagle's leather-clad shoulder at the various instruments fixed on to what in an aeroplane corresponds, I suppose, to the dashboard of an earth-bound automobile: the revolution gauge, which Eagle had explained to us; the watch; the map to roll up on a frame, like a blind; the compa.s.s, the height indicator. I felt secure and happy in the thought that my courage would at least make my captain respect me. He had shown us how his invention enabled the monoplane to balance itself in meeting every gust of wind, or falling into an "air pocket," without any effort from the conductor.

That a.s.surance hadn't been enough for Di, Winged Victory, G.o.ddess, and Huntress, but it was enough for humble Peggy. Besides, in the mood which had swept over me like a blinding flame of white fire, I didn't care what happened, provided it happened to Eagle March and me together. I should have liked him to aim straight for the sun, and never to come down again.
