CHAPTER XX

GORDON GOES UP IN THE AIR—ALSO HARRY

“Hey, Harry, come up here, will you? Gordon’s having a fit.”

“Honest, Harry, you ought to see him—he’s wound up!”

“On the level, Harry, he’s doing a hornpipe in the cabin—come on up,

don’t miss it!”

“Say, Harry, come up here till we get hold of you! How did you ever

manage to do that, anyway? It was great! Gordon’s waving the field glass

round his head—we can’t stop him!”

“Red Deer’s waiting to get his hands on you, old man—he’s got a scout

smile a yard long! You ought to get a special award for that! It was

great!”

“That was wonderful, Harry! You deserve a vote of thanks for licking

those college fellows, but I don’t see how you did it single-handed!”

The voices came from a group of scouts as they crowded at the yacht’s

rail. A rival group dragged him into a large, broad, dilapidated

fishing-smack, furnished with a gasoline engine.

“I want all you boys to get out of that thing and come aboard here,”

called Mr. Danforth, seconded by the half dozen of the troop whose

presence he had already secured.

Harry was literally pushed up the steps, the rest following him.

“How are you?” said Dr. Brent, grabbing him with one hand and pounding

his shoulder with the other. Mr. Danforth very cheerfully pushed Dr.

Brent out of the way. “Harry, my boy, how are you? It was magnificent!

You’re a wonder! How do you feel?”

“Fine and dandy,” smiled Harry.

“You must be all played out,” said Morrel. “Do you feel like a cup of

coffee?”

“Do I _look_ like a cup of coffee?” Harry laughed. “Where’s the Kid,

anyway?”

“The Kid went up in the air when you touched the finish line and hasn’t

come down yet. He told us all not to speak to you till he’d seen you

first—didn’t he, Tilford?”

“Sure, they’re all crazy about you here, Harry. You’ve got them

hypnotized. Gordon’s applied for a patent on you.”

“Say, Harry,” said Charlie Greer, the Beavers’ corporal, “we’ve been

writing to Oakwood. Where’ve you been, you old tramp? Gordon says you’ve

been doing light housekeeping on the top floor of old what’s-its-name

mountain.”

“Yes, I’ve been cooking for the Kid,” Harry answered. “He’s a whole

famine in himself.”

“Harry, those were regular rowing oars, weren’t they? How did you manage

’em, anyway?”

“Yes, they were as long as a spelling lesson. I believe it was that

placard those fellows had that helped me. I just couldn’t stand for

that. Hel-lo, Langford, old boy! Well, it’s good to see your pudgy

face!”

“Sh-h-h, here he comes,” cried Roy Carpenter, the Hawks’ patrol leader,

as Gordon’s head became visible above the companionway.

“Dearie me!” said Waring. “Let’s get from under!”

Gordon made a dive for Harry, and grabbed him. “Come down, come down!”

said he.

“Hello, Kid, down where?”

“Downstairs—she—she—”

“Go ahead, Harry boy,” said John Walden, knowingly. “By _all_ means,

go!”

But Harry had no choice.

“I thought _I_ would _wait_ until you had seen your _friends_,” said

Miss Crosby, shaking hands with him, “to _congratulate_ you for your

perfectly _wonderful_—”

“Did you have a good view, Miss Crosby?”

“Saw _everything_. And your friend explained things to me. Oh, he’s

_such_ an interesting little fellow, and he isn’t a _bit_ bashful, is

he?”

“Well, not so you’d notice it,” said Harry.

All of Mr. Danforth’s party had now to congratulate him, and in the

midst of it Raymond Vinton, corporal of the Hawks, appeared in the

doorway of the cabin.

“Mr. Arnold,” said he, with a profound air of mock deference, “Goodwin,

the daring aviator, has just sent a special message aboard asking if the

victor of the boat-race would like to take a little joy ride with him

over to Vermont. What shall I say?”

“Oh, _isn’t_ that just _lovely_!” said Miss Antoinette.

“Great,” answered Harry. “Things are certainly coming my way. Here,

Raymond, have you met Miss Crosby? Miss Crosby, Mr. Vinton is corporal

of the Hawk Patrol, such as it is, and he’s great on deducing. You just

waste a few minutes talking to him, won’t you, while I go on deck and

see if they’re trying to guy me.”

But they were not “guying” him. Sure enough, there in a boat at the foot

of the yacht’s steps sat a young man in a pair of greasy overalls. It

was Goodwin’s mechanic.

“Harry,” said Dr. Brent, “go by all means. It’s a chance not to be lost.

It isn’t every one who has such a dramatic opportunity of breaking his

neck. And when you return, if you do, you’ll find the troop up at the

float. If you are inclined to accept the poor hospitality of our humble

camp after all this,” he added with a humorous smile, “you’ll find us

waiting for you with the _Swan_.”

“The how?” asked Harry.

“The _Swan_, my boy, the boat you just saw. It is ours till September

first—ours and paid for. Harry, my boy, I can see by the look in your

eye that you are going to call your scoutmaster down for getting the

troop mixed up in this racing affair—but we couldn’t resist the

invitation, and your corporal, acting for you, voted to see it through.

But as for the _Swan_, Harry, I will not hear one word against her.”

“She looks as if she might do a mile or so an hour—with the current. Is

it _your_ joke, Doctor?”

“I hired her from a country youth after scouring the country. If you

choose to join the mockers, do so. I stand by the _Swan_, Harry, I’m

afraid it’s going to be a job to drag the boys off this yacht, but it’s

got to be done. Your friend Mr. Danforth is great!”

“They’re moving to Oakwood this Fall.”

“So I hear—that’s fine. Well, my boy, you’d better be off for your joy

ride.”

It was hard for Harry to say good-by to his genial host and the party on

the yacht, but he made the rounds of the cordial group, promising to see

them in the Fall—at least, the Danforths and Miss Crosby, who told him

that she would _surely_ be in Oakwood to see little Pen win the aero

contest.

With many expressions of good-will from Mr. Danforth, and a good deal of

mock deference from the troop, he got into the little boat and was rowed

ashore. The man in the greasy overalls led the way to a spacious green

near by, around which a rope fence had been stretched. The enclosure was

already lined with people. Others, more anxious to witness the flight

than to examine the machine, were comfortably seated on rocks or

sprawled on the grass outside. The man’s greasy overalls acted as a

password, and the crowd opened to let him cross the rope with Harry.

“That’s the fellow,” said some one, alluding to Harry, who gave no heed

to the comments on himself, for his interest was fixed on the center of

the field, where a perfect whirlpool of dust was rising, almost entirely

obscuring the aeroplane.

“They’re trying out the motor,” the man explained.

“Jiminy!” said Harry. “She goes some, doesn’t she?”

“Four hundred and seventy turns a minute,” said the man.

“How fast will that send her?” Harry asked.

“Forty miles an hour against a brisk wind.”

“How fast do you suppose that would send a small boat?”

“Now you’ve got me—they don’t have to figure so much for slip in the

water. Water’s a dense medium; but the air’s thin; you’ve got to

remember that. You interested in air work?”

“Why, yes,” said Harry, “but I’m not very well posted. What’s the pitch

of a propeller, anyway?”

“That’s its angle—you can’t get two aviators to agree about that. Mr.

Goodwin uses an eight-foot fan. You see, if we got the full benefit of

those four hundred and seventy turns we could make a streak of lightning

look like a snail, but you understand it’s like walking up a

treadmill,—you’ve got to walk like the mischief to keep ahead of the

game. Mr. Goodwin saw you win that race. Well, here we are.”

It surprised Harry a little to hear this grimy-faced, besmirched, greasy

young man talk so intelligently. But the experience is not uncommon for

those who interest themselves in aviation. A machinist or electrician

who lays down his ordinary work to devote his skill to the conquest of

the air, usually does so by reason of an ardent love of the science; and

there is not a more scientific and competent set of mechanics than those

who have attached themselves to successful aviators.

Goodwin, an active little man, with keen black eyes, came forward from

the little group surrounding the machine to welcome Harry.

“Ah,” said he, “that was a splendid race. I congratulate you. It

occurred to me that you might like to go up with me—eh?”

“Indeed, I should,” said Harry. “It was good of you to ask me.”

“Not at all, there’s an empty seat, if you’re not afraid.”

“Not much,” laughed Harry. “I’d have come a long way for this chance.”

“We haven’t got much air to stand on,” said Mr. Goodwin. “We’ll have to

speed a bit, I think.”

“We won’t get arrested for speeding, anyway,” suggested Harry.

“True enough,” laughed the aviator, as he went about his machine, trying

the wire bracing as one tries the strings of a harp. “If there’s

anything you want to know, my boy, just fire away. These reporters have

got me worked up so I’m a regular ‘Questions and Answers Column’ in a

newspaper. Now’s your chance—any posers?” He glanced whimsically at

Harry, who was already absorbed in an inspection of the graceful medley

of wing and wire and polished struts.

The machine was a biplane of forty-two feet lateral extent, with forward

stability planes similar to the Wright model. Instead of the tips of the

main planes being flexible, however, which is a chief feature of the

famous Wright machine, the lateral stability of the craft was controlled

by hinged wings, midway between the upper and lower planes at each

extremity, more after the fashion of the Van Anden device. Harry noticed

the curve of the main planes, for he had heard that here lay one of the

elusive secrets of aviation and a rule which would apply as well to a

boy’s model as to a man-carrying craft. The cross-ribs rose rather

abruptly from the front an inch or more above the forward horizontal

framing, then curved evenly back. The curve of the canvas was not the

arc of a circle at all, but a sort of humpback shape, cleverly designed

to catch the air in front, imprison it for the fraction of a second, and

pour it slowly out under the rear to make room for more. Many a stick

had been steamed and bent and dried and thrown away before that ugly,

but efficient, curve had been decided on.

“I must see that Pen has his planes flexed right if we have to go out

and harpoon a whale to get the whalebone,” thought Harry.

The strength and perfect rigidity of the machine were obtained by a

multiplicity of wire braces running in every direction. There was some

good reason for the presence of _every_ stick and brace, for every

little curve or turn. Even the canvas was laid on diagonally for the

bracing effect it might have. And though the machine looked simple,

considering its great responsibility, Harry could well believe that

every detail of it was the result of years of study and experiment.

For the aeroplane is not a discovery, nor an invention, either, in the

ordinary sense, but the combined application and the nice adjustment of

a dozen worked-out principles and a hundred ingenious devices for riding

the baffling and unstable air currents. Every jut and turn, every little

projection, every eccentric form of wing or plane or rudder, had its

scientific explanation. Yet most boys who see an aeroplane think they

can go and build one. But the money which is often expended for wood and

tools might better be used to purchase books containing the rudimentary

facts, a knowledge of which has made the conquest of the air possible

and goes far to make it safe.

Two seats, side by side, were cozily placed in the center between the

upper and lower planes, with the control device near at hand, and thus

every movement that a bird makes,—the flex of wing, the flap of tail,

the guiding tendency of this or that little stir of throat and

body,—was at the command of the operator. The telescope, the first tool

of aviation, had forced the swallow and the sea-gull to yield up their

secret, and here it was amid a network of frame and wire, at the service

of man.

Goodwin’s voice aroused Harry from his absorption. “No questions

answered after the train leaves,” he said. Harry felt very much at home

with him already. Here was a man, unaffected, simple, offhand,

competent, self-assured, and levelheaded. Nothing of the crank or the

visionary,—the kind of man who helps to advance the science of

aviation.

“I thought the propeller looked pretty big across the field,” said

Harry; “but it doesn’t look so big now. That all there is to the

motor,—just that that’s on the propeller?”

“That’s all, but it’s enough,” Mr. Goodwin answered.

“It makes a whole lot of fuss, anyway.”

“Right you are, and she fits like a suit of clothes. It isn’t wholly a

question of how much power you have, you know, but does the power fit?

That’s the question. See?”

“But doesn’t more power mean more speed?” Harry asked.

Goodwin laughed. “No, not exactly. The motor sustains the machine in

flight. Now, if there’s a good big supporting wing area, why, the engine

can be smaller—it’s got to be, in fact.”

“I’m afraid I’ll have to go to the foot of the class,” laughed Harry.

“So? Why? You never studied the subject? Well, see here, now, I’ll give

you the A B C of it and then we’ll hop in. The more spread there is, the

less supporting work the propeller has to do. So a powerful motor fits a

small machine, and a big machine takes less power to get the same

results. Now, you take Curtiss; he cuts down his planes, makes his

machine small, and what’s the answer? Does he get along with less power?

No, he needs more. You see, it isn’t a case of more power, more speed.

It’s having your power to _fit_ your machine. The propeller is more than

a propeller,—it’s a sustainer as well. Stop the propeller of a boat,

and the boat stands still. Stop an aero propeller, and down she comes.

Propeller keeps her up and keeps her going—two jobs. If you lessen your

support in one way, you must make it up in another. An aeroplane is

sustained by its speed with help from its planes. Well, now, the more

area you have, the less the motor has to do. You’ve heard aviation

compared to sailing, and that’s just the very thing that it isn’t a bit

like. Did you ever skate on thin ice? Well, there you have it. If you

want to keep from going in, skate fast. Now, if you put a large motor on

a large machine, you don’t get a normal increase of speed, by any means.

So you see, it’s not a question of power—it’s a question of a nice,

neat fit, as you might say.”

Harry remembered this later, when he saw more than one model aeroplane

lurch and flutter to the ground, to the amazement and disappointment of

its young maker. And when he returned to Oakwood, he remembered the

words of his aviator friend, “It isn’t a question of power—it’s a

question of nice, neat fit.”

“That’s a gnome motor,” concluded Mr. Goodwin; “revolving type,

air-cooled, saves the weight of a fly-wheel because the whole thing is a

fly-wheel in itself. Is she all right, Joe? Hop in, then, my boy.”

It was a moment that Harry Arnold never forgot. He would have liked to

study the machine a little longer before taking flight, for every detail

of it excited his keenest interest. It seemed almost incredible that

this man who climbed into the seat beside him could be so offhand about

so momentous a thing as mounting and riding the invisible air, but he

got in as if he were about to drive a familiar horse along a quiet

country road.

Two men stood behind the main planes, steadying them, and the mechanic

stood at the center, at the end of the bird-like tail, where the

vertical rudders were placed.

The aviator placed one foot conveniently near a small pedal beneath him.

His other foot and both of Harry’s rested on a bar, which was all that

kept their legs from dangling loosely over the edge of the lower plane.

On the outer side of each seat rose one of the supporting struts of the

plane above them, forming a convenient handle to steady oneself by.

Mr. Goodwin put his hands on either side of a wheel before him, placed

like the steering gear of an automobile. Beside him was an upright

lever. He wet his finger and held it up. Then he pulled out a little

strip of cheesecloth and held that up. It fluttered a little to one

side. “A little to the left, Joe,” said he. The man at the tail pulled

the machine about till it faced directly into the breeze—what little

there was. Then one of the men at the end came forward and began kicking

stones out of the way.

The suspense, to Harry, was delightful. Even here on the ground his

position was one of openness and freedom. Below him there was nothing

but the bar on which his feet rested. His position, little more than a

comfortable perch, gave him a first thrill of exhilaration.

“Run her out, Joe,” called the aviator.

There was a little jerk, and the machine started along the ground,

gathering speed till it clipped along at a good pace. Harry saw the men

at the ends of the planes pushing and steadying. Their chests were about

level with the lower plane. Presently, Goodwin put his foot on a little

button, and Harry nearly jumped from his seat from the sudden whir

behind him. Louder and more tumultuous it grew, till it rivaled the

noise of a sawmill. He saw one of the men at the plane ends reaching up.

Yes, they had left the ground. The frame vibrated, sending little

tremors through him. They were skimming along toward the encircling

crowd.

Presently, Goodwin, holding the wheel steadily, pulled it toward him.

The little pair of horizontal planes, resembling a box kite, which were

situated about twelve feet in front of them, turned slightly on their

axles so that Harry could not see between them now, and he was presently

conscious of a backward tilt of his body. They were rising. The noise of

the propeller just behind him was deafening. The whole frame was

convulsed with its movement. It was plain now that every wire was

needed.

Harry clasped the upright by his side and looked down. The line of

spectators blurred as the machine passed over it. Then, as they mounted

higher, following the tilt of the forward runner, things became clearer,

until, about three hundred feet from the ground, land and crowd took

their proper perspective, and Harry saw beneath him hundreds of upturned

faces.

He now felt scarcely any motion at all. When he closed his eyes, he

could not have told that he was moving, save for the wind in his face.

The deafening roar of the fan made questions impossible unless he

yelled, and the aviator seemed too much occupied to talk.

Soon, still holding the wheel stiff, Goodwin pushed it from him, and the

little planes in front twirled back to their former position, while the

back of Harry’s seat seemed to be pushing him forward. Now, he could

look straight between these two little forward planes again, and he knew

the machine was coming to an even keel. They were at a height of five

hundred feet or more, heading directly across the lake. Now and then,

Goodwin turned the wheel slightly, and once, as he did so, Harry glanced

behind him, and could just make out, through the whirring fan, the two

vertical planes at the end of the tail turning a little to right or

left, like a fish’s tail.

The seat was not equipped with springs, yet there was no jolting;

indeed, there was no sense of motion at all, except for the wind, and

the terrific straining and vibration of every part of the machine. Yet

the boats in the lake beneath them receded, and in a little while they

were above the Vermont shore.

Now, again, the forward planes turned slightly and the greater spreads

of canvas followed them obediently upward, till Harry reclined against

the back of his seat as in a steamer chair. When they came to an even

keel again he realized that this had been done to clear the tree-tops on

a hill well in from the Vermont shore. The absence of all sense of rapid

motion continually tempted him to release his hold of the supporting

bar, only to grasp it again whenever he looked at the tiny specks below,

and at the lake winding its way like a river on a map.

Now, for the first time, the operator placed his hand on the lever,

still holding the wheel stiff with the other hand. The hinged planes,

out at the end between the main planes, rose on the right-hand side and

sank on the left-hand side simultaneously. There was a sense of sudden

lift, the left end of the craft rose higher, higher, till the machine

swung full to the left. There was no jolting, only a delightful

consciousness of being swept around. Now, again, the crowd on the New

York side was clear to view. Again the lake, with its tiny, screeching

boats, stretched below them. When they were almost above the field

whence they had started, the vibration became less furious, the

propeller slowed down, stopped. A grateful silence prevailed.

“Anything wrong?” asked Harry, apprehensively.

“No, indeed,” said his companion.

The machine coasted slowly, easily, downward, held stable by the lever

control, with an ever so slight declining of the forward planes. Harry

did not know when they touched the ground. When he alighted, he saw the

tracks of the wheels for fully fifty feet behind. And it was only in

that way that he was able to determine where the aeroplane had left the

unstable and invisible currents of sustaining air for the homely but

reliable support of good old Mother Earth.

“Look at him,” said Goodwin, with a grin, as he climbed out.

“It’s easy to tell he’s one of those scouts we hear so much about,”

laughed a reporter who stood near. “First thing he does is to go back

and study the tracks!”
