VOL-PLANING TO EARTH
For a moment after Mr. Damon’s
announcement Tom did not reply. Mr. Swift, too,
seemed a little at a loss for something to say.
They did not quite know how to take their eccentric
friend at times.
“Of course I’ll be glad
of your company, Mr. Damon,” said Tom: “but
you must remember that my butterfly is not like
the Red cloud. There is more danger
riding in the monoplane than there is in the airship.
In the latter, if the engine happens to stop, the sustaining
gas will prevent us from falling. But it isn’t
so in an aeroplane. When your engine stops there—”
“Well, what happens?”
asked Mr. Damon, impatiently, for Tom hesitated.
“You have to vol-plane back to earth.”
“Vol-plane?” and there was a questioning
note in Mr. Damon’s voice.
“Yes, glide down from whatever
height you are at when the engine stalls. Come
down in a series of dips from the upper currents.
Vol-planing, the French call it, and I guess it’s
as good a word as any.”
“Have you ever done it?” asked the odd
character.
“Oh, yes, several times.”
“Then, bless my fur overcoat!
I can do it, too, Tom. When will you be ready
to start?”
“To-morrow morning. Now
you are sure you won’t get nervous and want
to jump, if the engine happens to break down?”
“Not a bit of it. I’ll
vol-plane whenever you are ready,” and Mr. Damon
laughed.
“Well, we’ll hope we won’t
have to,” went on Tom. “And I’ll
be very glad of your company. Mr. Fenwick will,
no doubt, be pleased to see you. I’ve never
met him, and it will be nice to have some one to introduce
me. Suppose you come out and see what sort of
a craft you are doomed to travel in to-morrow, Mr.
Damon. I believe you never saw my new monoplane.”
“That’s right, I haven’t,
but I’d be glad to. I declare, I’m
getting to be quite an aviator,” and Mr. Damon
chuckled. A little later, Tom, having informed
his father of the sending of the message. took his
eccentric friend out to the shop, and exhibited the
butterfly.
As many of you have seen the ordinary
monoplane, either on exhibition or in flight, I will
not take much space to describe Tom’s.
Sufficient to say it was modeled after the one in which
Bleriot made his first flight across the English channel.
The body was not unlike that of a
butterfly or dragon fly, long and slender, consisting
of a rectangular frame with canvas stretched over
it, and a seat for two just aft of the engine and controlling
levers. Back of the seat stretched out a long
framework, and at the end was a curved plane, set
at right angles to it. The ends of the plane
terminated in flexible wings, to permit of their being
bent up or down, so as to preserve the horizontal
equilibrium of the craft.
At the extreme end was the vertical
rudder, which sent the monoplane to left or right.
Forward, almost exactly like the front
set of wings of the dragon fly, was the large, main
plane, with the concave turn toward the ground.
There was the usual propeller in front, operated by
a four cylinder motor, the cylinders being air cooled,
and set like the spokes of a wheel around the motor
box. The big gasolene tank, and other mechanism
was in front of the right-hand operator’s seat,
where Tom always rode. He had seldom taken a passenger
up with him, though the machine would easily carry
two, and he was a little nervous about the outcome
of the trip with Mr. Damon.
“How do you like the looks of
it?” asked the young inventor, as he wheeled
the butterfly out of the shed, and began pumping
up the tires of the bicycle wheels on which it ran
over the ground, to get impetus enough with which
to rise.
“It looks a little frail, compared
to the big Red cloud, Tom,” answered
the eccentric man, “but I’m going up in
her just the same; bless my buttons if I’m not.”
Tom could not but admire the grit of his friend.
The rest of the day was busily spent
making various adjustments to the monoplane, putting
on new wire stays, changing the rudder cables, and
tuning up the motor. The propeller was tightened
on the shaft, and toward evening Tom announced that
all was in readiness for a trial flight.
“Want to come, Mr. Damon?” he asked.
“I’ll wait, and see how
it acts with you aboard,” was the answer.
“Not that I’m afraid, for I’m going
to make the trip in the morning, but perhaps it won’t
work just right now.”
“Oh, I guess it will,”
ventured Tom, and in order to be able to know just
how his butterfly was going to behave, with a
passenger of Mr. Damon’s weight, the young inventor
placed a bag of sand on the extra seat.
The monoplane was then wheeled to
the end of the starting ground. Tom took his
place in the seat, and Mr. Jackson started the propeller.
At first the engine failed to respond, but suddenly
with a burst of smoke, and a spluttering of fire the
cylinders began exploding. The hat of Mr. Damon,
who was standing back of the machine, was blown off
by the wind created by the propeller.
“Bless my gaiters!” he
exclaimed, “I never thought it was as strong
as that!”
“Let go!” cried Tom to
Mr. Jackson and Eradicate, who were holding back the
monoplane from gliding over the ground.
“All right,” answered the engineer.
An instant later the explosions almost
doubled, for Tom turned on more gasolene. Then,
like some live thing, the butterfly rushed across
the starting ground. Faster and faster it went,
until the young inventor, knowing that he had motion
enough, tilted his planes to catch the wind.
Up he went from earth, like some graceful
bird, higher and higher, and then, in a big spiral,
he began ascending until he was five hundred feet
in the air. Up there he traveled back and forth,
in circles, and in figure eights, desiring to test
the machine in various capacities.
Suddenly the engine stopped, and to
those below, anxiously watching, the silence became
almost oppressive, for Tom had somewhat descended,
and the explosions had been plainly heard by those
observing him. But now they ceased!
“His engine’s stalled!” cried Garret
Jackson.
Mr. Swift heard the words, and looked anxiously up
at his son.
“Is he in any danger?” gasped Mr. Damon.
No one answered him. Like some
great bird, disabled in mid flight, the monoplane
swooped downward. A moment later a hearty shout
from Tom reassured them.
“He shut off the engine on purpose,”
said Mr. Jackson. “He is vol-planing back
to earth!”
Nearer and nearer came the butterfly.
It would shoot downward, and then, as Tom tilted the
planes, would rise a bit, losing some of the great
momentum. In a series of maneuvers like this,
the young inventor reached the earth, not far from
where his father and the others stood. Down came
the butterfly, the springs of the wheel frame
taking the shock wonderfully well.
“She’s all right—regular
bird!” cried Tom, in enthusiasm, when the machine
had come to a stop after rolling over the ground, and
he had leaped out. “We’ll make a
good flight to-morrow, Mr. Damon, if the weather holds
out this way.”
“Good!” cried the eccentric
man. “I shall be delighted.”
They made the start early the next
morning, there being hardly a breath of wind.
There was not a trace of nervousness noticeable about
Mr. Damon, as he took his place in the seat beside
Tom. The lad had gone carefully over the entire
apparatus, and had seen to it that, as far as he could
tell, it was in perfect running order.
“When will you be back, Tom?” asked his
father.
“To-night, perhaps, or to-morrow
morning. I don’t know just what Mr. Fenwick
wants me to do. But if it is anything that requires
a long stay, I’ll come back, and let you know,
and then run down to Philadelphia again. I may
need some of my special tools to work with. I’ll
be back to-night perhaps.”
“Shall I keep supper for you?”
asked Mrs. Baggert, the housekeeper.
“I don’t know,”
answered Tom, with a laugh. “Perhaps I’ll
drop down at Miss Nestor’s, and have some apple
turnovers,” for he had told them or the incident
of hiring the new cook. “Well,” he
went on to Mr. Damon, “are you all ready?”
“As ready as I ever shall be.
Do you think we’ll have to do any vol-planing,
Tom?”
“Hard to say, but it’s
not dangerous when there’s no wind. All
right, Garret. Start her off.”
The engineer whirled the big wooden,
built-up propeller, and with a rattle and roar of
the motor, effectually drowning any but the loudest
shouts, the butterfly was ready for her flight.
Tom let the engine warm up a bit before calling to
his friends to let go, and then, when he had thrown
the gasolene lever forward, he shouted a good-by and
cried:
“All right! Let go!”
Forward, like a hound from the leash,
sprang the little monoplane. It ran perhaps for
five hundred feet, and then, with a tilting of the
wings, to set the air currents against them, it sprang
into the air.
“We’re off!” cried
Mr. Damon, waving his hand to those on the ground
below.
“Yes, we’re off,”
murmured Tom. “Now for the Quaker City!”
He had mapped out a route for himself
the night before, and now, picking out the land-marks,
he laid as straight a course as possible for Philadelphia.
The sensation of flying along, two
thousand feet high, in a machine almost as frail as
a canoe, was not new to Tom. It was, in a degree,
to Mr. Damon, for, though the latter had made frequent
trips in the large airship, this mode of locomotion,
as if he was on the back of some bird, was much different.
Still, after the first surprise, he got used to it.
“Bless my finger ring!” he exclaimed,
“I like it!”
“I thought you would,”
said Tom, in a shout, and he adjusted the oil feed
to send more lubricant into the cylinders.
The earth stretched out below them,
like some vari-colored relief map, but they could
not stop to admire any particular spot long, for they
were flying fast, and were beyond a scene almost as
quickly as they had a glimpse of it.
“How long will it take us?”
yelled Mr. Damon into Tom’s ear.
“I hope to do it in three hours,”
shouted back the young inventor.
“What! Why it takes the train over five
hours.”
“Yes, I know, but we’re
going direct, and it’s only about two hundred
and fifty miles. That’s only about eighty
an hour. We’re doing seventy-five now,
and I haven’t let her out yet.”
“She goes faster than the Red cloud,”
cried Mr. Damon.
Tom nodded. It was hard work
to talk in that rush of air. For an hour they
shot along, their speed gradually increasing.
Tom called out the names of the larger places they
passed over. He was now doing better than eighty
an hour as the gage showed. The trip was a glorious
one, and the eyes of the young inventor and his friend
sparkled in delight as they rushed forward. Two
hours passed.
“Going to make it?” fairly howled Mr.
Damon.
Tom nodded again.
“Be there in time for dinner,” he announced
in a shout.
It lacked forty minutes of the three
hours when Tom, pointing with one hand down below,
while with the other he gripped the lever of the rudder,
called:
“North Philadelphia!”
“So soon?” gasped Mr.
Damon. “Well, we certainly made speed!
Where are you going to land?”
“I don’t know,”
answered the young inventor, “I’ll have
to pick out the best place I see. It’s
no fun landing in a city. No room to run along,
after you’re down.”
“What’s the matter with
Franklin Field?” cried Mr. Damon. “Out
where they play football.”
“Good! The very thing!” shouted Tom.
“Mr. Fenwick lives near there,”
went on Mr. Damon, and Tom nodded comprehendingly.
They were now over North Philadelphia,
and, in a few minutes more were above the Quaker City
itself. They were flying rather low, and as the
people in the streets became aware of their presence
there was intense excitement. Tom steered for
the big athletic field, and soon saw it in the distance.
With a suddenness that was startling
the motor ceased its terrific racket. The monoplane
gave a sickening dip, and Tom had to adjust the wing
tips and rudder quickly to prevent it slewing around
at a dangerous angle.
“What’s the matter?”
cried Mr. Damon, “Did you shut it off on purpose?”
“No!” shouted Tom, “Something’s
gone wrong!”
“Gone wrong! Bless my overshoes! Is
there any danger?”
“We’ll have to vol-plane
to earth,” answered Tom, and there was a grim
look on his face. He had never executed this feat
with a passenger aboard He was wondering how the butterfly
would behave. But he would know very soon, for
already the tiny monoplane was shooting rapidly toward
the big field, which was now swarming with a curious
crowd.
