<h2 id="c7">CHAPTER VII <br/><span class="small">THE SWAMP GIVES UP A CLUE</span></h2>
<p>Two courses were offered to the Sky Patrol
with Jeff.</p>
<p>“We can try to drop down into the fog,”
called Larry to Dick as their pilot, with closed
throttle, nosed down to get closer to the scene
of the tragedy.</p>
<p>“But we can’t set down or do anything—and
we can’t see much for the fog,” objected Dick.
“I think we ought to go back and drop a note
onto the yacht, telling the people to come here
in a boat.”</p>
<p>Larry agreed with this sensible suggestion
and Dick, scribbling a note, passed it to Sandy.
After a glance the younger of the trio gave it to
Jeff. The pilot nodded when he read it.</p>
<p>Again the engine roared as they swung
around, laying a course to take them above the
rolling mist, toward the end of the island around
which—or beyond which—the yacht should be
cruising or waiting.</p>
<div class="pagenum" id="Page_55">55</div>
<p>“It will be hard to find the yacht in this fog,”
Sandy mused, but as they flew along he, with
the others, scanned the low clouds for some
open rift through which to catch a possible
glimpse of the water craft. A slantwise gust
of wind crossed the cockpits, giving them new
hope. If a breeze came to blow aside the mist
they might have better chances to see the yacht.</p>
<p>In steadily increasing force, and gradually
coming oftener, the puffs of moving air increased
their confidence.</p>
<p>The fog was thinning under them, blowing
aside, swirling, shifting.</p>
<p>With the breeze from the new direction, as
they steadily got closer to the end of the island,
coming over a spot where a break in the cloud
showed brown-yellow sand and rushing white
surf beyond the wide level beach, Sandy’s alert
eyes caught sight of something for an instant.
Prodding Jeff, he indicated the object.</p>
<p>As Jeff swooped lower, inspecting, Dick
caught a good glimpse of the tilted, quiet focus
of Sandy’s gesture.</p>
<p>“There’s the amphibian,” Dick muttered.
“Stranded—cracked up, maybe. But—if we
could get down and land, we could use her, two
of us could, to go to the swamp and see what’s
there—before anybody else gets to the life preserver
the jewels must have been tied to.”</p>
<div class="pagenum" id="Page_56">56</div>
<p>He passed forward, through Sandy, a note.</p>
<p>Jeff agreed, made his bank and turn, as
Sandy saw the drift of a plume of smoke on
the horizon, to get into the wind.</p>
<p>Coming back, dropped low, Jeff scanned the
beach.</p>
<p>“It looks safe for a landing—pretty solid
beach,” Larry concluded, and evidently Jeff felt
the same way for he climbed in his turning
bank, got the wind right and came down, using
his engine with partly opened throttle to help
him settle gradually until the landing wheels
touched when the tail dropped smartly, the gun
was cut, and the sand, fairly level and reasonably
well-packed, dragged them to a stop.</p>
<p>Hurriedly the youthful Sky Patrol tumbled
onto the sand, digging cotton plugs out of their
ears now that the roar of the motor no longer
made them essential.</p>
<p>“It’s the amphibian, and no mistake!” Larry
cried, running down the beach toward the titled
craft.</p>
<p>“If she isn’t damaged,” he told Dick, “you
and Jeff, or Jeff and I could fly to the swamp
in her.”</p>
<div class="pagenum" id="Page_57">57</div>
<p>“You go.” Dick was generous to the friend
he admired, and who was almost a year older.
“It would need a cool, quick head to handle
whatever you might find in the swamp. You
go.”</p>
<p>That also was Sandy’s opinion when, after a
rapid inspection, they agreed with Jeff that the
amphibian, set down with only a strained tail
skid and a burst tire in the landing wheel gear,
was usable.</p>
<p>“But there’s no gas,” objected Larry, noting
the indicator in the control cockpit. “See, the
meter says zero!”</p>
<p>“It was that way when I looked before,”
Sandy said. “That was why I didn’t think anybody
meant to use it——”</p>
<p>“Easy to fool you on that,” Jeff declared.
“It’s been disconnected. I wouldn’t be surprised
if that-there tank wasn’t nearly half full. They
had it all fixed and ready——”</p>
<p>“Let’s go, then,” urged Larry. “Dick, look
over the pontoons for strains, will you? She
may have struck one of them—she has tipped
over part way, maybe hit one of the pontoons.”</p>
<div class="pagenum" id="Page_58">58</div>
<p>Dick, examining with the thoroughness of an
expert, with Jeff’s and his chum’s life perhaps
depending on his care, stated that he saw no
damage to the waterproofed coverings of the
water supports. Declaring that they would
stand by and watch the airplane, Sandy and
Dick watched Larry and Jeff get settled, Dick
spun the propeller to pump gas into the still
heated cylinders, Jeff gave the “switch-on—contact!”
call, Dick, pulling down on the “prop,”
sprang aside to avoid its flailing blades, and the
amphibian’s engine took up its roar.</p>
<p>Acting as a ground crew, Dick righted the
craft by thrusting up the wing which was evidently
not seriously damaged, while Sandy, as
the motor went into its full-throated drone,
shook the tail to lift the skid out of the
clogging sand. His eyes shielded from the sand,
blasted back by the propeller wash, he leaped
sidewise and backward as the elevators lifted
the tail and the amphibian shook itself in its
forward lunge, lifted, flew within two inches
of the sand, and then began to roar skyward.</p>
<p>“He’s drawing up the wheels, now,” Sandy
called to Dick.</p>
<p>“They won’t be any good, with that burst
tire—he’ll have to set down in water anyhow,”
Dick explained. Sandy nodded.</p>
<p>Waving to his two watching comrades as they
grew smaller to his peering eyes, Larry turned
his attention to the work of scanning, from the
forward place, all the indented shore line, north,
that the mist had uncovered.</p>
<div class="pagenum" id="Page_59">59</div>
<p>To their left, as they sped on, the lighthouse
poked its tower out of the drifting, dispelling
fog.</p>
<p>Soon Jeff dropped low, diminished the throb
of the engine, cruising while Larry kept watch.</p>
<p>“Yonder it is!” Larry’s hand gestured ahead
and to the side.</p>
<p>Jeff, peering, located the wing of the seaplane,
the fuselage half submerged in muddy
channel ooze, the tail caught on the matted eel-grass.</p>
<p>In the mouth of a broad channel they touched
water and ran out of momentum with the wings
hovering over the grassy bank to either side.</p>
<p>“Now what?” demanded Jeff. “We can’t go
in any closer.”</p>
<p>Already Larry had his coat and shoes off.
Stripping them off, and with no one to observe,
removing all his clothes, he lowered himself
onto a pontoon and thence to the water,
chilly but not too cold on the hot June afternoon.</p>
<p>Striking out with due care not to get caught
by any submerged tangle of roots or grasses,
Larry swam the forty feet.</p>
<p>“The pilot’s in his cockpit—” he gasped.
“He’s—he isn’t——”</p>
<div class="pagenum" id="Page_60">60</div>
<p>“Get that collapsible boat on the back of the
tank, there!” urged Jeff, “and come back for
me.”</p>
<p>It took inexperienced Larry some time to
open and inflate the tubular rubber device used
for supporting survivors of any accident to the
seaplane while afloat.</p>
<p>“He’s—I think he’s alive,” Jeff declared fifteen
minutes later. “That’s a bad slam he’s had
on the forehead, though.” He lifted the silent
pilot’s bruised head, put a hand on his heart,
nodded hopefully and bade Larry dash water in
the man’s face.</p>
<p>The cold, salty liquid seemed at first to have
no effect.</p>
<p>“He must have hit himself trying to get out,”
Larry surmised.</p>
<p>Jeff shook his head.</p>
<p>“His parachute isn’t loosened or unfolded,”
he responded, working to get the spark of life
to awaken in the man he bent over. “No, Larry,
from the looks of things—somebody hit him,
while they were away up in the air, and jumped—with
that life preserver.”</p>
<p>“Where is he now? If only I could get my
hands on him. I wonder who it was?”</p>
<p>Jeff paid no attention to Larry’s natural
anger and wonder.</p>
<div class="pagenum" id="Page_61">61</div>
<p>“He’s coming around—fella—who did this-here
to you?”</p>
<p>The eyes fluttered open, the lips trembled.</p>
<p>Larry, clinging to a brace, his feet set on a
strut, bent closer.</p>
<p>“What happened? Who done this?” repeated
Jeff.</p>
<p>The man, before he sank again into silence,
uttered one word—or half a word:</p>
<p>“Gast—” he muttered.</p>
<p>“Gast—was it somebody named Gaston?”
asked Jeff.</p>
<p>The man did not respond.</p>
<p>“Never mind,” Larry urged. “Can you get
him into the boat, somehow, Jeff? You ought
to land him at a hospital—or at the nearest airport.
There’s a medical officer at every one—for
crack-ups. Or, fly and telephone for help!”</p>
<p>“Would you be afraid to stay here if I take
him to an airport?”</p>
<p>“No!” declared Larry, stoutly.</p>
<p>Without further words or conscious movements
from the silent pilot they managed to get
him unhooked from his belt and parachute harness,
to lower him, precariously limp, into the
rubber boat, which Larry held onto as Jeff, half
supporting his inert co-pilot, propelled it to
their own craft.</p>
<div class="pagenum" id="Page_62">62</div>
<p>As they moved slowly along Larry, fending
off a clump of tough grass into which the breeze
sought to drift their rubber shell, caught sight
of something dimly white, far in among the
muddy grass roots.</p>
<p>He left his support, swam across the smaller
channel, carefully, and secured the life preserver
which had dropped into a heavy clump
of the grass and then had floated free of the
mud, held only by the end of a tangled string—and
the skin of an empty, oilskin pouch, torn
and ripped to tatters, that hung to the cord.</p>
<p>When Larry rejoined Jeff, he flung the life
preserver into the space behind the control seat
of the amphibian, leaving it there without comment
as he helped Jeff to lift and drop the still
unconscious man into his own forward place.</p>
<p>Then, pushing off in the rubber boat, he sat
still, his dry clothes in a compact bundle in the
boat thwarts, while Jeff let the wind and tide-run
carry his amphibian out of the channel to
where he could get sea space for a start, to get
the amphibian pontoons “on the step” from
which, with his silent cargo of human tragedy,
Jeff lifted into air and went out of sight, southbound.</p>
<p>Sitting until he dried, Larry donned his garments.</p>
<div class="pagenum" id="Page_63">63</div>
<p>“Gast—” he murmured. “Gast——”</p>
<p>Had he heard any name around the airports
like Gaston?</p>
<p>“Well,” he reflected, “its something, now, anyway.
We can look for a Frenchman—and learn
if there’s one named Gaston.”</p>
<p>He sculled back to get under the shading, up-tilted
wing of the seaplane, studying what he
saw of its half submerged after place.</p>
<p>“Glory-gosh!” he exclaimed, staring.</p>
<p>There, neatly arranged, was the row of
chewed bits of gum!</p>
