about and, pointing to shore, cried:

"Oh, look, Flossie!"

"We're going right toward a big, dark hole!" said the little girl.

"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!"

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?

CHAPTER XIV

HELEN'S VISIT

While the two children sat in the drifting rowboat, which was being
slowly blown toward the island shore again, Flossie suddenly gave a
little jump, which made the boat shake.

"What's the matter?" asked Freddie. "Did something bite you?" for his
sister had started, just as you might do if a fly or a mosquito suddenly
nipped your leg.

"No, nothing bit me," she answered. "But I felt a splash of rain on my
nose and---- Oh, Freddie! Look! It's going to be a thunder-lightning
storm!"

Freddie, whose eyes had seen nothing but the cave, now looked up at the
sky. The blue had become covered with dark clouds, and in the west there
was a dull rumble.

"I--I guess it is going to rain," said Freddie slowly.

"I know it is!" Flossie answered. "There's 'nother drop!"

"I felt one, too," said her brother. "It went right in my eye, too!" and
he winked and blinked.

"And there's another one on my nose!" cried Flossie. "Oh, Freddie! What
are we going to do? I haven't an umbrella!"

For a moment the little boy did not know what to do. He looked at his
coat, but that was still wet, though it had been spread out on the seat
to dry. He could not wrap that around Flossie, as he thought at first he
might.

The wind, too, was blowing harder now, and there were little waves
splashing against the side of the boat. But the wind did one good thing
for the children--it blew the boat toward shore so much faster, and
shore was where they wanted to be just now. They knew they had drifted
out too far, and they were beginning to be afraid. The shore of the
island looked very safe and comfortable.

"We can get under a tree--that will be an umbrella for us," said
Flossie. "Aren't you glad we're going on shore, Freddie?"

"Yes, but I guess we can get in a better place out of the rain than
under a tree, Flossie."

"Then we
