<div>SOMETHING OF A MYSTERY</div>
</div></div>
<p class='c010'>Our hero found the gasoline tanks pretty well
emptied of oil. He realized that the “juice” on
hand would not admit of a long flight. Satisfied,
however, that there was sufficient fuel to fly the
<i>Comet</i> out of its resting place and down to level
ground, Dave got to the pilot post and operated
the self-starter.</p>
<p class='c011'>The biplane arose promptly to the occasion.
A little deft guiding cleared the hill. The machine
and its occupant came safely and gently to
a new landing place in a field nearby. Hiram
and the farmer hastened to the spot as Dave
alighted.</p>
<p class='c011'>“I call that purty cute,” announced the farmer,
a good deal interested. “Now then, stranger,
what about them damages?”</p>
<p class='c011'>“Just what I said,” replied Dave. “You have
done us a great service and we appreciate it.
There is your money.”</p>
<p class='c011'><span class='pageno' id='Page_55'>55</span>“Say, you’re square and white,” declared the
farmer, overjoyed at the possession of so much
cash.</p>
<p class='c011'>“We try to be,” answered Dave, pleasantly.
“Just sign that receipt, will you? The aeroplane
company will pay for this, and I want my voucher
all straight and regular.”</p>
<p class='c011'>Dave wrote out a receipt on the back of a card
and the man signed it. Then the young aviator
proceeded to the automobile.</p>
<p class='c011'>“Can’t I help you some?” inquired the farmer,
accommodatingly.</p>
<p class='c011'>“If you will loan us a tin pail for a bit it will be
of service to us,” replied Dave. “There is plenty
of spare gasoline in the auto tank, Hiram,” he explained.</p>
<p class='c011'>It did not take the boys long to transfer enough
of the gasoline to last the <i>Comet</i> for a home
flight. Dave arranged to fly the machine and directed
Hiram to take charge of the automobile.</p>
<p class='c011'>It was about two o’clock in the afternoon when
the adventurers reported on the aero grounds.
Mr. Brackett was delighted at their success and
Elmer was fairly overjoyed. No damage whatever
had been done to the biplane, it was found,
after a careful inspection of the machine.</p>
<p class='c011'>“I say, Dave,” spoke Hiram, as he and his
chief sat eating a fine dinner sent by Mr. Brackett
from the restaurant; “there’s a good deal about
this business that puzzles me.”</p>
<p class='c011'><span class='pageno' id='Page_56'>56</span>“I suppose that is true,” responded the young
aviator, with a slight smile. “What principally
is troubling you, Hiram?”</p>
<p class='c011'>“Why, the whole proceeding. If somebody
wanted to put us out of business, why didn’t they
sink the airship somewhere or burn it up?”</p>
<p class='c011'>“I think they counted on the <i>Comet</i> remaining
undiscovered until long after the other entries
had started,” said Dave.</p>
<p class='c011'>“Spite, then?” suggested Hiram.</p>
<p class='c011'>“No, I don’t think that.”</p>
<p class='c011'>“Then if that Vernon had anything to do with
it——”</p>
<p class='c011'>“I am satisfied that he did,” declared Dave.
“His object was not to keep Elmer from getting
out of the country, though.”</p>
<p class='c011'>“Why, what else could it be?” questioned
Hiram in wonderment.</p>
<p class='c011'>“I shall tell you later, Hiram,” replied Dave
in quite a serious way. “The fact is, there are
some things about stealing the airship that I do
not entirely understand myself. When I have
posted myself on those details, I fancy I shall
have a decidedly interesting story to tell you and
Elmer.”</p>
<p class='c011'>“Say, can I ask you one question?” propounded
Hiram, and then, as Dave nodded in
assent, he added: “Has that girl, and your visit
to the city and the appearance of Vernon at the
Hampton Flats got anything to do with it?”</p>
<p class='c011'><span class='pageno' id='Page_57'>57</span>“Everything, in my opinion,” answered the
young airman, gravely.</p>
<p class='c011'>“Humph!” commented Hiram. “A romance
and a mystery, eh?”</p>
<p class='c011'>“Hardly, Hiram,” responded Dave gravely.
“It is business, pure and simple. I will say this
much to you at the present time: whatever dealings
I am having with Mr. Deane, the father of
the girl you saw, may involve all the skill and
nerve the crew of the <i>Comet</i> have at their command.”</p>
<p class='c011'>The young airman had given his interested assistant
a good deal to think over. Hiram, however,
and in fact everybody about the place, were
soon immersed in things strictly professional. At
noon the following day the race around the world
was to start. There were not a large number of
entries, but every individual contestant had his
own pet machine and his coterie of friends and
admirers.</p>
<p class='c011'>The field was a lively scene all day. The various
machines made trial flights. Then there was
the packing of supplies, which necessarily had to
be of limited volume. All of the contestants in
turn visited the office of the Aero Association to
receive definite route instructions. There was a
good deal of red tape to go through, credentials
to secure, and arrangements made for reporting
progress to headquarters from set points along
the route.</p>
<p class='c011'><span class='pageno' id='Page_58'>58</span>The young aviator and his assistants spent
nearly an hour over a blue print map which had
been furnished each of the contestants by the
management of the event. Hiram got out a
geography and studied out the situation in a more
detailed way. Elmer, at the suggestions of Dave,
made two copies of the list of points from which
the <i>Comet</i> was to report progress.</p>
<p class='c011'>The boys were interrupted in this congenial
work by the appearance of one of the hangar
men at the door of the living tent. He beckoned
to Dave, who at once went outside, received some
message, and called back to his friends:</p>
<p class='c011'>“I’ve got to go to the city, fellows. Won’t
be over two hours. Keep a close watch on everything
until I get back.”</p>
<p class='c011'>“Wonder what’s up now?” remarked Hiram,
speculatively. Then he went to the door and
looked out. “H’m,” he observed, “Dave has a
good deal of mysterious business on hand, it
seems to me.”</p>
<p class='c011'>“Where has he gone?” asked Elmer only
casually, for he was deeply absorbed in his work.</p>
<p class='c011'>“To the city he said, and say, in that same
automobile that brought the young lady here day
before yesterday.”</p>
<p class='c011'><span class='pageno' id='Page_59'>59</span>“Well, it must be something important to take
Dave away from here at just this time,” commented
Elmer.</p>
<p class='c011'>The young aviator reappeared about two hours
later. The chauffeur who had come for him
brought him back. Dave came into the living
tent all briskness and cheery as usual. The watchful
Hiram, however, whispered cautiously to
Elmer that “he acted as if he had something
heavy on his mind.”</p>
<p class='c011'>The boys made frequent visits to the <i>Comet</i>
during the evening. Hiram noticed that Dave
seemed very solicitous that a double watch should
be kept over the machine during the night. He
hired two extra men to spell the regular watchmen,
and gave them close directions as to their
care of the biplane.</p>
<p class='c011'>A band of music woke up the three young airmen
early in the morning. It announced a reception
to some French experts who had arrived
to take part in the international flights. Dave
was out of bed first, as usual, and bolted out of
the place, anxious to see if all was well with the
<i>Comet</i>.</p>
<p class='c011'>Hiram and Elmer began to dress. They felt
buoyant and eager for the work of the day. In
sport, as Elmer finished dressing first, he made a
grab for the pillow on the cot Dave had occupied
and sent it hurtling at the head of his companion.</p>
<p class='c011'><span class='pageno' id='Page_60'>60</span>“That’s the last pillow you’ll see for a long
time to come,” he announced. “Hello! Why,
Hiram, look here!”</p>
<p class='c011'>The speaker stood stock still, gazing spellbound
at the head of the cot whence he had taken
the pillow. Hiram, joining him, looked down
like himself in sheer, startled wonder.</p>
