our boat. Maybe it belongs here and we'd better leave it."

"Then you'd better tie it," said Flossie. She and her brother had been
told something of the care of boats, and one rule their father had given
them was always to tie a boat when they got out of it. In the excitement
of the storm the children had forgotten this at first, but now Flossie
remembered it.

"Yes, I'll tie the boat," Freddie said, "and then whoever owns it can
come and get it."

It did not take him long to scramble around to the edge of the little
cove. Once there, he tied the rope of the boat fast to a large stone
that was half buried in the ground. Making sure it would not slip off,
Freddie came back to where Flossie waited for him.

She was quite ready to leave the cave, and soon the two children were
outside under the trees that still were dripping with rain.

The sun was now shining. Flossie and Freddie had had an adventure, they
thought, and that was fun for them.

"Which way is home--I mean where our camp is?" asked Flossie, as she and
Freddie walked along together.

"Down this way," he said. "See the path?"

Certainly there was a path leading away from the cave, but Freddie did
not stop to think it might lead somewhere else than to Twin Camp. It was
a nice, smooth path, though, and he and Flossie set out along it not at

"I'm hungry," said the little girl, "and I want to get home as soon as I
can."

"I'm hungry, too," Freddie said. "We'll soon be home."

But the children might not have reached the camp soon, only that a
little later they heard their names called in the wood, and, answering,
they found Nan and Bert looking for them in the goat wagon drawn by
Whisker.

"Where in the world have you been?" asked Bert of his little brother and
sister.

"Oh," answered Freddie, "we've been out in a boat and in a cave and we
only had cookies to eat and they were wet and----"

"We heard a noise in the cave. Maybe it's a bear, an' if it is Freddie
can take his popgun the next time we go there. Can't you, Freddie?"

"Dear me!" laughed Nan. "What's it all about?"

Then the two small twins told more slowly what had happened to them, and
Nan and Bert told their small brother and sister that, coming back from
their little trip, they had found Mrs. Bobbsey much worried because she
could not find Flossie and Freddie.

"Then it began to rain," said Nan, "and we were all as worried as could
be. We looked at our boats, and whe
