<h2><SPAN name="c24"><span class="h2line1">CHAPTER XXIV</span> <br/><span class="h2line2">Attack from the Deep</span></SPAN></h2>
<p>For the next three days, activity went on at a
feverish pace. Camp was hastily set up again on the
same island, and even when it was late in the day,
Biff, Derek, and Uncle Charlie would try another spot
hoping to locate the fishery.</p>
<p>They dived from sunup to sundown. The only rest
period for Biff and Derek came when Uncle Charlie
dashed into Trinité to replenish the air tanks.</p>
<p>The piles of shucked oyster shells grew higher and
higher. No pearls were found. The boys worked
desperately against time, but as the first day passed,
then the second, then the third, they worked with
heavy hearts. The time limit was drawing near.</p>
<p>Dietz made no further attacks. He was content
now to fight his battle in the courts. But the pearl
fishers knew he was still in the area. They saw his
boat from time to time. He was keeping his distance,
but he was still watching.</p>
<div class="pagenum" id="Page_160">160</div>
<p>However, even by using binoculars, Dietz would
be unable to determine whether the boys located
the pearl fishery. He could only learn this by finding
out the results of the daily diving. He would have to
know what the opened oysters yielded. For this reason,
a nightly guard was kept. Although Dietz was going
to use the courts, the search party didn’t want him to
know if and when they did locate the fishery. Crunch
insisted on taking the night guard duty. He also
worked during the day. Biff often wondered when
the big Indian slept.</p>
<p>Although the danger from Dietz had lessened,
Charlie Keene kept reminding the boys of the danger
that always awaited them when they were diving.</p>
<p>It struck suddenly and viciously on the fourth morning
of their diving.</p>
<p>Biff and Derek were down in forty-eight feet
of water. They had been digging out oysters for half
an hour. Basket after basket had been hauled up.</p>
<p>Waiting for his basket to be lowered to him, Biff
was suddenly spun around by a swirl of water. It
felt as if he had been caught in a whirlpool. Biff
cleared his mask. He looked around. Coming at him
out of the murky dark waters was a giant shark. The
killer swept by within a foot, then turned and slashed
back.</p>
<p>Biff looked frantically for Derek. He saw his glimmering
white shape ten feet away. Approaching
Derek was a second shark.</p>
<p>The sharks hadn’t struck yet. It seemed they were
inspecting their prey, waiting before their razor-sharp
teeth tore at the boys’ bodies. Biff swam quickly
over to Derek. He grabbed his arm and pointed. The
two huge sharks were motionless, their wicked eyes
on the boys.</p>

<div class="pagenum" id="Page_162">162</div>
<p>Biff took a deep breath, raised his mask just enough
to clear his mouth, and shouted as loud as he could.
His shout, of course, made no sound. But Biff knew
that the force of the breath expelled by his shout
would send a shock wave in the direction of the
sharks. He had read that this was one of the best ways
of delaying an attack by an undersea monster.</p>
<p>The shout worked. The sharks swam around the
boys in circles. But Biff knew that any second they
would strike.</p>
<p>There was no time now to go by the book in getting
to the surface. Biff jammed his face mask on, quickly
cleared it of water, grabbed Derek by the arm, and
shoved him upward. He himself followed, propelling
himself as fast as he could. Both boys had jettisoned
their belts instantly.</p>
<p>Breaking the surface, Biff gasped to his uncle,
“Sharks!”</p>
<p>Charlie Keene lost no time. He grabbed Derek,
who was closer, and hauled him into the boat. Crunch
lifted Biff in.</p>
<p>They were no sooner in the boat than two shark
fins cut the water, circling nearer and nearer to the
craft.</p>
<p>Biff and Derek lay gasping on the bottom of the
boat. Their rapid ascent had drained their bodies of
oxygen and strength.</p>
<p>Biff’s uncle quickly started the motor and got away
from the spot at full speed. He had seen the size of
the sharks. They were big enough to overturn the
dory if they struck.</p>
<div class="pagenum" id="Page_163">163</div>
<p>By the time they reached the island camp, the boys
had somewhat recovered. But Biff was still shaking
as if he had a chill, and Derek’s face was drawn and
white.</p>
<p>The narrow escape the boys had undergone was
not without its reward, however.</p>
<p>All four of the pearl fishers—Crunch was now one
of them—were shucking oysters after a rest and the
noonday meal.</p>
<p>Biff, growing more and more bored with the tough
job of opening and examining oysters, was about to
discard a shell when he noticed a raised protuberance
in the exact center on the shell. He took off his
glove and dug at the raised part with a fingernail. His
excitement grew. Seconds later he dug out an almost
perfectly shaped white pearl.</p>
<p>“I’ve got one! I’ve got one!” he shouted.</p>
<p>The others crowded around him. Biff handed the
pearl to his uncle.</p>
<p>Charlie Keene inspected it carefully.</p>
<p>“I’m no expert, Biff. But the color, and particularly
the shape, of this pearl—I’d say you’ve found
a really valuable one.”</p>
<p>“How much? How much is it worth?”</p>
<p>“I couldn’t tell. Only an expert could. But it’s a
white pearl—they’re the most valuable. And it’s almost
perfectly round. It could be worth several thousands
of dollars.”</p>
<p>“Whoopee!” Biff shouted. “Let me at more of those
oysters!”</p>
<p>Interest quickened. The four worked in silence, but
they worked fast. Oyster after oyster was opened,
carefully inspected, then tossed aside.</p>
<div class="pagenum" id="Page_164">164</div>
<p>Derek found the next one. It, too, was perfectly
shaped, but slightly smaller than the one Biff had
found.</p>
<p>It was Crunch who came through with the topper.
A big grin on his face, Crunch came over to Biff and
held our his huge hand. In the center of his palm
was a pearl twice the size of those already found.</p>
<p>“This is it! This is it! Look at Crunch’s pearl!”</p>
<p>Again they all crowded around. This was a real
beauty. It didn’t take an expert to know that Crunch
had found a pearl of great value.</p>
<p>“Think we’ve found it, Uncle Charlie?” Biff asked.
“I mean the fishery Derek’s father discovered?”</p>
<p>“It could be, Biff. It darn well could be.”</p>
<p>Biff looked at Derek. There was a smile on the
Dutch boy’s face. Then the smile disappeared.</p>
<p>“What’s the matter, Derek?” Biff asked.</p>
<p>“My father found black pearls,” Derek replied.</p>
<p>“They’re all colors, Derek,” Uncle Charlie told
him. “Actually, the black ones aren’t as valuable as
the white. They’re valuable, all right, especially if
they’re perfectly matched, as those two your father
sent us were.”</p>
<p>“I’d feel a lot more certain that we’d found the
right place if we found some black ones.”</p>
<p>“Let’s go back down when we finish these oysters,”
Biff said.</p>
<p>“With all those sharks?”</p>
<p>“Funny thing about sharks,” Uncle Charlie said.
“Although they are the pearl diver’s greatest enemy,
they can also help produce the pearl.”</p>
<p>“How?” Biff wanted to know.</p>
<div class="pagenum" id="Page_165">165</div>
<p>“The best pearl is the perfectly round pearl. The
foreign body which gets into the oyster must be perfectly
round to produce the perfect pearl. These
round objects are the eggs of parasitic worms. The
adult worms are the parasites of sharks.”</p>
<p>“So where you find sharks, you can find pearls?”
Biff asked.</p>
<p>“Not exactly, Biff. What I mean is this: where
there are pearl fisheries, the perfect pearls come from
the eggs the shark’s parasites lay.”</p>
<p>No more pearls were found in the batch dug that
morning. It was growing late in the afternoon. They
decided to go back to the morning’s site, and if no
sharks were in evidence, they’d try half an hour’s
diving.</p>
<p>They returned to the same site. Biff and Derek
went overside. Before they started scooping up oysters,
they made sure no sharks were around. Biff
loaded one basket and sent it up. He saw Derek send
one up. Biff filled another. He looked at his watch.
They’d been down twenty minutes.</p>
<p>“One more basket,” Biff said to himself, “and
we’ll call it a day.” He turned in Derek’s direction
to signal to him that this was the last basket. Roiling
water ahead pushed an alarm button in Biff’s mind. He
increased his speed.</p>
<p>Derek was being attacked savagely by giant band
shells. They swarmed around him, slashing at him
with their claw-shaped, horny shells.</p>
<p>Biff whipped out his knife and shot into action.</p>
<div class="pagenum" id="Page_166">166</div>
<p>The giant band shells, many times the size of the ordinary
conch shell, are the only known shell fish to attack
human beings. They have a tough, scimitar-shaped
muscle which they use as a door to close the opening
at the large end of the shell. While other conches use
this muscle only as a door, the giant band shell uses it
as a weapon. The end of the muscle is hooked and razor
sharp. The giant band shell springs at a man, using
a second muscle to propel itself, then slashes and cuts
with its “door.” In moments, it can cut a man’s body
to shreds.</p>
<p>These giants were surrounding Derek. Up close,
Biff could see Derek had already received several cuts.
Biff knew what this meant. Sharks would come racing
through the water, crazed with hunger by the smell of
blood.</p>
<p>Biff slashed away at the band shells with his knife.
It did no good. The giant shells continued their attack,
some of them turning on Biff. There was only
one thing to do. Derek was nearly helpless. Biff
grabbed him. He shoved him upward with all his
strength. Derek disappeared above him. Now the
band shells turned their full attack on Biff. He fought
them off, trying at the same time to rise. Several of
them tried to fasten onto Biff’s legs. He kicked out
desperately. He thrust down with his open hands and
shot upward. The slower moving band shells were
left behind. Biff reached the surface. He lost no time
in scrambling into the boat. Uncle Charlie already had
pulled Derek, bleeding, into the boat.</p>
<p>Biff just made it. No sooner was he in the boat
than the waters around it boiled with maddened sharks,
searching for the source of the blood.</p>
