<h2>CHAPTER XIII</h2>
<h3>IN THE CAVE</h3>
<p>"Look out, Freddie! Don't you go wadin' too far!" cried Flossie, as she
saw her little brother kick off his low shoes, quickly roll off his
stockings, and start out toward the boat which now a strong puff of wind
had blown quite close to the island shore.</p>
<p>"I'll be careful," he answered. "Mother said I could wade up as far as
the wig-wag cut on my leg, and I'm not there yet."</p>
<p>Freddie had several scars and scratches on his legs, reminders of
accidents he had suffered at different times. One scar was from a cut
which he had got when he had fallen over the lawn mower about a year
before. It was the biggest cut of all, and was near his right knee. He
called it his "wig-wag" cut, because it was a sort of wavy scar, and
when he wanted to go in wading his mother always told him never<span class="pagenum"><SPAN name="Page_138" id="Page_138">[138]</SPAN></span> to go
in water that would come above that cut, else he would get his
knickerbockers wet.</p>
<p>So now he was careful not to go out too far. He watched the water rising
slowly up on his bare legs as he waded along on the sandy bottom of the
lake toward the drifting boat.</p>
<p>"If you took a stick you could reach it now," called Flossie.</p>
<p>"I guess I could," Freddie said.</p>
<p>"I'll hand you a stick," Flossie offered, looking for one along the
shore. There were many dead branches, blown from the trees, and she soon
handed Freddie a long one. With it the little boy was able slowly to
pull the boat toward him, and he had soon shoved the "nose," as he
sometimes called the bow, against the bank of the island.</p>
<p>"Now I can get in!" laughed Flossie. "And I won't have to take off my
shoes and stockings either," and into the boat she scrambled.</p>
<p>"Oh!" exclaimed Freddie. "Are you going to get in the boat?"</p>
<p>"I am in," answered his sister. "Aren't you comin' in, too?"</p>
<p>Freddie looked at the boat, at his sister, at<span class="pagenum"><SPAN name="Page_139" id="Page_139">[139]</SPAN></span> the lake, and at his
shoes and stockings on the shore. Then he said:</p>
<p>"Well, it doesn't belong to us—this boat don't."</p>
<p>"I know," said Flossie. "But you pulled it to shore and we can keep it
till somebody comes for it. And we can make-believe have a ride in it.
Momsie won't care as long as it's fast to the shore. Come on, Freddie!"</p>
<p>It seemed all right to Freddie when Flossie said this, especially as the
boat was close against the shore. He put on his shoes and stockings,
drying his feet in the grass, and then he took his seat in the boat
beside his little sister.</p>
<p>"Now we'll play going on a long voyage," she said. "We'll take a trip to
New York and maybe we'll be shipwrecked."</p>
<p>"Like Tommy Todd's father," added Freddie.</p>
<p>"Yep. Just like him," said Flossie, "only make-believe, of course."</p>
<p>"And I'll be captain of the ship, and you can be a sailor," went on
Freddie. "It'll be lots of fun!"<span class="pagenum"><SPAN name="Page_140" id="Page_140">[140]</SPAN></span></p>
<p>Bert and Nan had gone riding in the goat wagon to the other end of the
island, Mr. Bobbsey was at his office and Mrs. Bobbsey, with Dinah, was
working about Twin Camp, so there was no one to watch Flossie and
Freddie. Mrs. Bobbsey supposed they were playing safely at the lake
shore, and, as a matter of fact, they were on shore, though in the boat.</p>
<p>"I wonder whose it is?" said Freddie, when they had made a make-believe
voyage safely to New York, after having been shipwrecked at
Philadelphia—a place the little twins remembered, as one of their aunts
lived in that city.</p>
<p>"Maybe it's a gypsy boat," said Freddie.</p>
<p>"Or else it's the one the blueberry boy had," added his sister.</p>
<p>"Oh, yes, maybe it is his!" cried Freddie. "And if it is, didn't we
better ought to take it to him?"</p>
<p>"How?" asked Flossie.</p>
<p>"Why, we can push it along the shore with sticks, 'cause there's no oars
in it, and when we see him picking blueberries we can holler to him to
come an' get his boat."<span class="pagenum"><SPAN name="Page_141" id="Page_141">[141]</SPAN></span></p>
<p>Flossie thought this over a few seconds. Then she said:</p>
<p>"Let's!"</p>
<p>This meant she would do as Freddie said. The twins did not stop to
consider whether they were doing something they ought not to do. They
planned to keep near shore, and that was as much as they remembered of
what their mother had told them—that they were not to go out on the
lake in any boat without her permission or their father's.</p>
<p>"But paddling along the shore isn't going out," said Freddie. "Anyhow,
mother and father would want us to give back the boat to the blueberry
boy, wouldn't they?"</p>
<p>"Course," said Flossie. "Get another stick, Freddie, and we can poke the
boat along, and we won't have to go far out at all."</p>
<p>In a little while the two twins were shoving the drifted boat along the
shore by pushing the ends of their sticks into the soft bank. The boat
was of good size, and it was flat-bottomed, which meant it would not
easily tip over. Flossie and Freddie each knew how to row, though they
had to have oars made especially for<span class="pagenum"><SPAN name="Page_142" id="Page_142">[142]</SPAN></span> them. But they knew how to keep in
the middle of a boat, and never thought of rocking it or changing seats,
so they were much safer than most children of their age would have been.</p>
<p>Having lived near Lake Metoka all their lives, they knew more about
boats and water than perhaps some of you small boys and girls do; and
they could both swim, though, of course not very far, nor were they
allowed to try it in deep water.</p>
<p>"Oh, this is lots of fun!" cried Flossie, as she and Freddie poled the
boat along. "This is real trav'lin'!"</p>
<p>"But we mustn't go too far," said Freddie, not quite sure whether or not
his mother would think what he and his sister were doing was just right.
"As soon as we see the blueberry boy we must give him his boat and go
back home."</p>
<p>"If he wants to row us back, can't we let him?" asked Flossie.</p>
<p>"Yes, but he can't row, 'cause there are no oars in the boat," said
Freddie.</p>
<p>"Maybe he has 'em with him. I guess that's<span class="pagenum"><SPAN name="Page_143" id="Page_143">[143]</SPAN></span> what happened," went on the
little girl. "You know we take the oars out of our boat and put them up
on shore. And then maybe the blueberry boy forgot to tie his boat."</p>
<p>"And it blew away and we found it," finished Freddie. "Come on, push
hard, Flossie. Let's go fast and make believe we're a steamboat."</p>
<p>That suited Flossie, and they were soon pushing the boat along the shore
quite fast. They went out past a little point on the island, some
distance away from their own camp, the white tents of which they could
see.</p>
<p>"Oh, how nice the wind is blowing!" cried Flossie, after a bit. "I don't
hardly have to push at all, Freddie."</p>
<p>"That's good," he said. "We'll be a sailboat instead of a steamboat. If
we only had a sail now!"</p>
<p>"Maybe you could hold up your coat," suggested his sister. "Don't you
remember that shipwreck story mother read us. The men in the boat held
up a blanket for a sail. We haven't any blanket, but if you held one end
of your coat and I held the other it would be a sail."<span class="pagenum"><SPAN name="Page_144" id="Page_144">[144]</SPAN></span></p>
<p>"We'll do it!" cried Freddie, as he slipped off his jacket. It was
small, but when he and his sister held it crosswise of the boat, the
wind, which had begun to blow harder, sent the boat along faster than
the children had been pushing it.</p>
<p>"Oh, this is fine!" Freddie cried. "I'm glad we played this game,
Flossie."</p>
<p>"So'm I. But look how far out we are, Freddie!" Flossie suddenly cried.
"We can't reach shore with our sticks."</p>
<p>Freddie looked and saw that this was so.</p>
<p>"I wonder if we can touch bottom out here," he said. "I'm going to try."</p>
<p>He let go of his coat, and as it happened that Flossie did the same
thing, the little jacket was blown into the water.</p>
<p>"Oh!" cried Flossie. "Oh! Oh!"</p>
<p>"I can get it!" excitedly shouted Freddie. "I'll reach it with my
pushing stick."</p>
<p>He managed to do this, taking care not to lean too far over the edge so
the boat would not tip. Then he caught the coat on the end of the stick
and pulled his jacket into the boat.</p>
<p>"Oh, it's all wet!" cried Flossie.<span class="pagenum"><SPAN name="Page_145" id="Page_145">[145]</SPAN></span></p>
<p>Freddie did not stop to tell her that every time anything fell into the
water it got wet. Instead, he began to search in his pockets.</p>
<p>"What's the matter—did you lose something?" asked Flossie.</p>
<p>"I guess we can eat 'em after they dry out," said Freddie, after a bit,
pulling out some soaked sugar cookies.</p>
<p>Freddie spread them out on one of the boat-seats where the sun would dry
them, and then he wrung from his coat as much water as he could. Next he
spread the jacket out to dry, Flossie helping him.</p>
<p>All this time the children failed to notice where they were going, but
when they had seen that the soaked cookies were getting dry and had
eaten them, Freddie looked about and, pointing to shore, cried:</p>
<p>"Oh, look, Flossie!"</p>
<p>"We're going right toward a big, dark hole!" said the little girl.</p>
<p>"That isn't a hole—it's a cave," Freddie said. "Maybe it's a pirate
cave, and there'll be gold and jewels in it. The wind is blowing us and
our boat right into it!"<span class="pagenum"><SPAN name="Page_146" id="Page_146">[146]</SPAN></span></p>
<p>And that was what was happening. The wind had changed, and, instead of
blowing the boat away from the island, was blowing it toward it. And
directly in front of Flossie and Freddie was a big hole in the steep
bank of the island shore. As Freddie had said, it was a cave. What was
in it?<span class="pagenum"><SPAN name="Page_147" id="Page_147">[147]</SPAN></span></p>
