ere too far away to hear him. Bunker
then sat down on a stone. He did not know what to do. He looked over to
the main shore, where he could just see the white tents of Camp
Rest-a-While.

"Well, if we don't come back pretty soon, Mr. Brown will know something
is wrong, and he'll get another boat and come over here," thought
Bunker. "Then I can tell him what has happened, and we can go and look
for the children. I guess they'll be all right. All I can do is to
wait."

All this while Bunny and Sue were eating their lunch. They were not
frightened now, and they very much enjoyed their little umbrella-sail
excursion in the boat and the picnic they were having.

But, pretty soon, it began to grow cloudy, and then it began to rain.

"I don't like this," said Sue. "I want to go home, Bunny."

Bunny, himself, would have been glad to be in camp with his father and
mother, but he thought, being a boy, he must be brave, and look after
his little sister, so he said:

"Oh, I guess this rain won't be very bad, Sue. We'll go back into the
woods, under the trees. Then we can keep dry. And we'll take the lunch,
too. There'll be enough for supper."

"Will we have to stay here for supper?" asked Sue.

"Maybe," answered Bunny. "But if we do it will be fun. Come on!"

It was now raining hard. Bunny carried the lunch basket, with the
bottle of milk--now half emptied--in one hand. The other hand clasped
Sue's. They went back in the wood a little way, and, all at once, Bunny
saw something that made him call:

"Oh, Sue! Here's a good place to get in out of the rain!"

"What is it?" Sue asked.

"A cave!" cried Bunny. "It's a regular cave, like robbers live in! Come
on, Sue! Now we're all right! Oh, this is fun!" and Bunny ran forward
into the dark hole in the side of the hill--right into the cave he ran.

CHAPTER XXIV

"WHO IS THERE?"

Sue did not run into the cave after her brother Bunny. She stood,
hugging her doll close to her, under a big, evergreen tree, so that only
a few drops of rain splashed on her.

Bunny Brown, standing in the "front door" of the cave, as he called it,
looked at his sister.

"Come on in, Sue!" he called. "It's nice here, and you can't get wet at
all."

"I--I don't want to," Sue answered.

"Why not?" Bunny wanted to know.

"'Cause," and that was all Sue would say. Then it began to rain harder,
and the drops even splashed down through the thick branches of the
evergreen tree.

"Oh, c
