<h2 id="c19">CHAPTER XIX <br/><span class="small">A BAFFLING DISCOVERY</span></h2>
<p>“Somebody had to be in that hydroplane,”
Sandy mused. “They were there to switch on
the light, to turn the boat, and to set it on the
new course!”</p>
<p>Quickly he peered to the side and back, downward
at the water in the place where the first
landing flare had settled into the water.</p>
<p>Just a little closer to their position, should
have been the spot where the clever miscreant
might have abandoned the boat.</p>
<p>Sooner than that, Sandy guessed, the unknown
person could not have quit the hydroplane:
otherwise the turning from shore would
have continued and the hydroplane, instead of
proceeding in a straight course away from land,
would have swept in a wide circle, round and
round.</p>
<p>“There’s no life preserver in the boat either—so
that’s what the mystery man used to swim
away with—Mr. Everdail’s jewels!” he added.</p>
<div class="pagenum" id="Page_161">161</div>
<p>Straining his eyes, he peered, looking for a
bobbing head, a round white object supporting
a body, as the flare died. Dick, arguing in much
the same fashion, stared from the other side of
the fuselage and gave a shout of elation.</p>
<p>“There!”</p>
<p>His arm pointed.</p>
<p>Sandy prodded Jeff, and quickly the pilot,
much recovered, gave Larry his instructions.</p>
<p>“Nose up—we’re getting too low. Right! Now
a right bank—not too steep. Don’t get excited.
That-there lad in the hydroplane headed her
outbound and then took to the water. Now we’re
heading in—steady with that-there rudder—don’t
try to jam her around—now she’s all
right. Level off and hold her as she is.”</p>
<p>Larry obeyed all instructions, doing the work
as Jeff gave the order. Larry was rapidly growing
sure of his ability.</p>
<p>He fought down the excitement that wanted
to express itself in hasty manipulation of his
controls and kept a steady hand and a cool
brain.</p>
<p>Dick, scribbling hurriedly, passed a note to
Sandy, who read it in the light of the flash, and
then passed both paper and light to Jeff.</p>
<div class="pagenum" id="Page_162">162</div>
<p>Dick, recalling a wide, spacious cement-floored
parking space at a nearby bathing
resort, had suggested “setting down” there. As
he read the note Jeff shook his head.</p>
<p>“Dangerous trying to land there!” was the
note Jeff passed back as Larry flew the airplane
at just above stalling speed toward the
shore. Dick agreed. After all, there might be
automobiles in the parking lines, and the light
might be bad for Larry. Even using a power-stall
by which, with the engine going and a flat
gliding angle, the airplane could settle gradually
closer until it took the ground with hardly a jar,
the maneuver would not be safe, Dick admitted.</p>
<p>“Here comes another ’plane!” Sandy called
out, taking the flashlamp from Jeff again as the
older pilot handed it back. “He’s flying right
after us.”</p>
<p>They all located the drone of the other engine.</p>
<p>“Steady, Larry!” Jeff cautioned. “Hold as
you are. That-there is our amphibian—and I
reckon the boss is doing the control job.”</p>
<p>The amphibian, as they made out its pontoon
understructure, came fairly close alongside. Its
speed was almost identical with their own and
at first all four occupants of the land crate wondered
who was in it, and why.</p>
<p>“Signaling!” cried Larry, cutting the gun and
turning to observe.</p>
<div class="pagenum" id="Page_163">163</div>
<p>“All right, buddy,” admonished Jeff. “Stick
to your job. Sandy or Dick will read the dots
and dashes—if he’s using Morse code——”</p>
<p>“He is spelling out something with his flashlight,”
Sandy decided, as he saw short flickers
and longer dashes of light while the amphibian
kept a course within close range but at safe
wing distance.</p>
<p>“I’ve got it!” Dick passed forward his paper.</p>
<p>“‘G-i-v-e r-e-p-o-r-t,’” Sandy read, and as
he handed Jeff the note, Sandy, using his own
light, sent back the Morse code answer:</p>
<p>“Man swimming ashore with life belt.”</p>
<p>Then, with the beam directed in the path the
mysterious unknown must have taken, he tried
to show the occupant of the amphibian what he
meant.</p>
<p>Evidently the endeavor succeeded, for the
amphibian dived, and took to the water, while
Larry, directed by Jeff, swept around in a circle
out of range if the amphibian rose unexpectedly,
but within visual range of its maneuvers.</p>
<p>Watching intently, his comrades saw that the
amphibian kept on toward shore in a taxiing
course on the water surface.</p>
<p>A shout greeted the advent of an automobile
on a shore drive. As it swung around a curve,
close to the water, its bright headlights fell in
a sweeping line across the water—and picked
out a round, white dot bobbing, vividly lit, in
the rays.</p>
<div class="pagenum" id="Page_164">164</div>
<p>The amphibian was headed directly for it.</p>
<p>It went close, just as the swinging lights
swerved and were gone.</p>
<p>“Drop another flare!” shouted Larry.</p>
<p>Sandy caught and relayed the suggestion as
they retained their swinging curve.</p>
<p>With the glare from the dropped light picking
out things in sharp silhouette, they saw a man
clamber out onto a pontoon and rescue the floating
prize.</p>
<p>“Now, I wonder if that is Mr. Everdail—or
if it’s somebody else?” thought Larry, correcting
for a tendency of the nose to fall away.</p>
<p>“Whoever it is,” he concluded, “he can’t get
away. He has the life preserver. But we have
superior speed. And a good tankful of fuel.”</p>
<p>He glanced at the gauge to reassure himself,
made an almost automatic correction of a wing
tip, pushing up in a gust of air as he saw that
his surmise about fuel was correct.</p>
<p>There was no need for the concern that all
four felt for the moment.</p>
<div class="pagenum" id="Page_165">165</div>
<p>As soon as it got under way again and took
up its climb, the amphibian, coming to their
level, showed its pilot holding up the life preserver,
as the flare still settled toward the
water. In the glow they recognized the triumphant,
smiling millionaire.</p>
<p>The flight back to the landing field was without
event. Larry made the landing first, and
his companions tumbled out to join the waiting
cluster of people while they all “took hold” to
run the airplane out of the way so that the spiraling
amphibian, its wheels down, could shoot
the flare-lit field, and land.</p>
<p>“Here!” Mr. Everdail was triumphant as he
threw the life preserver out of his cockpit to
Larry. “As I live and breathe, that life preserver
ought to be in a museum!” He grinned
as he came to the ground. “That’s the flyingest
life preserver I ever saw—first it goes joy-riding
in a seaplane, then in the ‘phib’ and now it
runs off on the Sound and comes riding back
with me.”</p>
<p>“Let’s see what’s in that-there!” Jeff urged.
“That’s most important, right now!”</p>
<p>The crowd trooped into the hangar, where
Larry, at Jeff’s direction, switched on the overhead
electric lamps.</p>
<p>Close around Mr. Everdail, Jeff, Captain
Parks and Miss Serena, with the youthful Sky
Patrol in their midst, the rest of the sailors, and
most of the house servants gathered.</p>
<div class="pagenum" id="Page_166">166</div>
<p>“Somebody give me a good knife,” ordered
Mr. Everdail. “We’ll cut this thing to ribbons
and get rid of all the suspense!”</p>
<p>Larry held out the round, heavy inflated
“doughnut” as half a dozen pocket knives were
unclasped and held out to the millionaire.</p>
<p>Taking the long-bladed one Sandy produced,
Mr. Everdail advanced.</p>
<p>“Hold on, sir!” Captain Parks stepped forward.</p>
<p>“What’s the matter, Parks?”</p>
<p>“Son, turn that preserver over—let me see
the other side.”</p>
<p>Surprised, Larry did as he asked.</p>
<p>They all saw the captain’s face assume an
expression of disgust.</p>
<p>“That’s not the life preserver from the
<i>Tramp</i>,” he grunted.</p>
<p>“What?”</p>
<p>“You know as well as I do, sir,” the yacht
captain turned to his employer to answer his
amazed cry, “you know that all the life preservers
have the yacht’s name and port painted
on them.”</p>
<p>“And that’s so, too,” said the mate, advancing
and backing up his captain’s declaration.</p>
<p>“No, sirree!” Captain Parks stated. “That’s
not the yacht property. It hasn’t any marks on
it at all.”</p>
<div class="pagenum" id="Page_167">167</div>
<p>“Maybe it’s the one off the hydroplane,”
Larry was dejected, but not convinced that the
life preserver was a strange one to all.</p>
<p>“Not that!” the mate declared. “It’ud be
marked <i>Scorpion</i>. No, Mr. Everdail, this is no
life preserver we’ve ever seen before.”</p>
<p>“Well, anyhow, I’m going to cut into it.”</p>
<p>“Please, sir, do that!” urged Sandy. “I can
be sure it’s the one we found in the airplane
fuselage, anyhow—I remember that little rusty
stain in the cover.”</p>
<p>“Cut,” said Jeff, “but something tells me
you’ll waste time.”</p>
<p>Sandy, Larry and Dick shook their heads,
looking hopeful.</p>
<p>But Jeff was right!</p>
