<div>A MYSTERIOUS VISITOR</div>
</div></div>
<p class='c010'>Dave Dashaway stood at the entrance to the
hangar of the <i>Comet</i> at Sylvan Park. The machine
had done nobly on the trial field near the
Capitol city. Now it was housed among the
group of competitors in the great race. The
pick of the world’s best airmen was represented
at this international meet, and the scene was one
of activity and interest.</p>
<p class='c011'>The airship boys were comfortably housed in
the living tent just beyond the hangar. At first
upon arriving it had been decided to have Elmer
stay away from the field until the final start was
made. This procedure was actuated by the fear
that the troublesome Vernon might put in an appearance
and continue to annoy and hamper the
young airman. The next morning, however, Mr.
Brackett arrived.</p>
<p class='c011'>“I am here for two reasons,” he had announced.
“First, I wish to see our last word in
biplanes, the <i>Comet</i>, sail off on the race I know
<span class='pageno' id='Page_25'>25</span>you are going to win. Next, I want to be on hand
if that troublesome Vernon tries any more of his
tricks.”</p>
<p class='c011'>“I hardly think he will attempt to follow us
this far,” was the expressed opinion of our hero.
“It would cost him some money, and it would be
somewhat dangerous for him to work any
trumped-up charge with so many of our airmen
friends around to defeat his plans.”</p>
<p class='c011'>“There is still more than that,” remarked the
airship manufacturer, in a confident way.</p>
<p class='c011'>“What do you mean, father?” inquired his
son.</p>
<p class='c011'>“Just this,” answered Mr. Brackett, “as I left
home my lawyer, who was looking up Vernon,
put in my possession some documents that will
enable me to baffle this wretch at every turn. I
only hope he will appear. It will be to receive
a final quietus, believe me.”</p>
<p class='c011'>The big event was now only three days distant.
The <i>Comet</i> was in perfect shape for its long
flight. The boys had used prevision and judgment
in all their preparations; and had not really
much to do. Dave, however, was kept pretty
busy with a constant stream of visitors. Professional
and otherwise, those who had seen descriptions
of their splendid machine in the public
prints were eager to view that work of mechanical
perfection. A group of them were now gathered
inside the shelter building. Experts were examining
and admiring the <i>Comet</i>.</p>
<p class='c011'><span class='pageno' id='Page_26'>26</span>It pleased Mr. Brackett to exhibit this last
masterpiece from the Interstate Aero Company’s
factory. As a strictly passenger carrying biplane
it had never been equalled. Mr. Brackett showed
all its improvements, from the new chain drive
apparatus to the high pitch revolution screws.
The original model of the <i>Comet</i> had represented
a machine weighing over one thousand five hundred
pounds with a spread of thirty-eight by sixty-three
and one-half feet, pitch speed five thousand
six hundred feet, average flight record fifty miles.
The old style rear propeller drive had been supplanted
by tractor screws. The tubing truss underneath
the center section and skid bracing also
in the rib or plane section was a new feature. A
divergence from the popular headless screw traction
design was the use of the Curwell type of outriggers.
This did away with an attachment at
the end of a monoplane type of fuselage.</p>
<p class='c011'>It was almost dusk when the visitors began to
depart. Dave was giving orders to two of the
hangar men to lock up the machine for the
night, when an automobile drew rapidly up to the
spot. As the young aviator glanced casually at
the machine, he saw that besides the chauffeur it
contained a veiled, girlish form.</p>
<p class='c011'><span class='pageno' id='Page_27'>27</span>The chauffeur stopped the machine directly before
the living tent. He leaped from the auto
and approached Mr. Brackett, who was standing
near by.</p>
<p class='c011'>“Can you direct me to the <i>Comet</i> hangar?”
he inquired, touching his cap politely.</p>
<p class='c011'>“This is the place,” explained the manufacturer.</p>
<p class='c011'>“And Mr. Dave Dashaway—do you know
where I can find him?”</p>
<p class='c011'>The young airman overheard this conversation.
He stepped forward at once with the words:</p>
<p class='c011'>“I am Dave Dashaway. What can I do for
you?”</p>
<p class='c011'>The chauffeur moved aside with a movement
of his head towards the automobile. Its occupant
leaned slightly forward, and extended a
daintily gloved hand. As Dave advanced and
lifted his cap she spoke to him in a low, tremulous
tone.</p>
<p class='c011'>“I wish to speak to you for a few moments,
Mr. Dashaway,” she said. “In private,” she
added, with a glance at the several persons in
view.</p>
<p class='c011'>“Certainly,” responded Dave readily, but in
some wonderment. “There is our office, miss.
May I assist you?”</p>
<p class='c011'>The little lady uttered a fluttering sigh as our
hero helped her from the machine and led the
way to the living tent. Hiram had just lighted
<span class='pageno' id='Page_28'>28</span>a lamp. Both he and Elmer regarded their
friend’s companion in some surprise. They were
too well bred, however, to stare at the newcomer,
who seemed timid and uncertain. The boys
moved quietly from the tent, Dave set a stool for
his visitor and seated himself at a little distance,
awaiting her pleasure.</p>
<p class='c011'>“You must not think it strange that I have
come to you, Mr. Dashaway,” she said. “I—that
is, I was directed to you by a very close
friend, who knows you well.”</p>
<p class='c011'>“Ah, indeed?” spoke the young airman.</p>
<p class='c011'>“Yes, I bring you a letter from a friend of
my dear father, who is as well a close friend of
your own—Mr. Robert King.”</p>
<p class='c011'>“I am pleased and interested at once, Miss,”
said Dave, trying to set the young lady at her ease
under such strange surroundings. “Mr. King
is, indeed, a close friend, and his friends are very
welcome.”</p>
<p class='c011'>“You are most kind,” said the visitor, nervously
searching for the letter in question, and in
her confusion lifting her veil. From her face
Dave saw that she was about his own age. There
was an anxious look in her eyes. She finally
found the letter, and handed it to the young airman
with the explanation:</p>
<p class='c011'>“We went to Mr. King where he is sick at his
home in New York City.”</p>
<p class='c011'><span class='pageno' id='Page_29'>29</span>“Yes, I know,” said Dave. “He wrote me
only last week.”</p>
<p class='c011'>“I am Edna Deane,” proceeded the young
lady. “My father is himself something of an
invalid and could not come with me to-day. We
went to Mr. King to ask his help in a case where
he only, or somebody like him, could be of any
assistance.”</p>
<p class='c011'>“You mean in the aviation way?” inquired
Dave, getting interested.</p>
<p class='c011'>“Yes, Mr. Dashaway,” replied the young girl.
“I want my father to explain to you about it.
He has written our address on the envelope—Hampton
Flats. He wishes to have you make an
appointment to meet him, if you will be so kind.”</p>
<p class='c011'>“I certainly shall be glad to be of service to
any friends of the gentleman who taught me all
I know about sky sailing,” began Dave, and then
he added very heartily: “Surely I will come, Miss
Deane. To-morrow morning, if you wish. Shall
we say at ten o’clock? I have some few things
to attend to that will take up my time until
then.”</p>
<p class='c011'>“My father will be very glad,” murmured the
girl, gratefully.</p>
<p class='c011'>A glance at the letter from the veteran aviator,
Mr. King, had at once influenced Dave. The
old airman wrote briefly, but to the point. He
stated, that were he in shape to do so, he would
<span class='pageno' id='Page_30'>30</span>at once assist Mr. Deane. He asked his former
assistant to act in his place, could he at all arrange
to do so. Mr. King hinted that there was an
opportunity for a great humane act. He said he
was sure that when Dave knew its details, his
generous heart would respond to an unusual appeal
for help in a strangely pathetic case.</p>
<p class='c011'>Meantime Hiram and Elmer had strolled to a
distance. They passed Mr. Brackett, who was
seeing to it that the hangar men safely housed
his pet biplane for the night. Hiram looked
curiously at his companion.</p>
<p class='c011'>“Well,” he observed, “sort of mysterious, Elmer;
eh?”</p>
<p class='c011'>“You mean that young lady?”</p>
<p class='c011'>“I do. Automobile—mysterious veiled visitor,”
said Hiram with a smile.</p>
<p class='c011'>“Maybe it’s another of those venturesome college
girls wanting to make a flight for the name
of it. Dave will tell us when he sees us. No
nonsense about him. He’s too busy for romance.”</p>
<p class='c011'>“That’s so. There she goes, Elmer,” announced
Hiram.</p>
<p class='c011'>The boys made out Dave, cap in hand, walking
beside the automobile as it started up slowly, and
conversing with its occupant. Then, curious and
eager to learn the merits of the interesting episode,
they proceeded towards the living tent,
<span class='pageno' id='Page_31'>31</span>approaching it by a roundabout route so as not
to look as if they were “snooping around,” as
Hiram put it.</p>
<p class='c011'>Just as they neared it, Elmer grasped the arm
of his companion, bringing him to a halt with a
startling: “S—st!”</p>
<p class='c011'>“What is it?” demanded Hiram, staring ahead
in the direction in which the glance of his companion
was fixed.</p>
<p class='c011'>“Look for yourself,” whispered back Elmer,
pointing to a crouching figure just behind the tent.
“See—a man, a lurker, a spy! Who do you
suppose he is; and what is he up to?”</p>
