o'clock came, then ten, but still no sign of life on board.

Captain George grew a little uneasy. He did not know that the
Meadow-Brook Girls had eaten their breakfast more than an hour before
that, and that the girls were watching the boys, chuckling over the
perplexity of the latter.

Once more the motor boat was taken out. As they neared the houseboat for
a second time they saw Harriet Burrell come out to the after deck, and
stooping over examine the anchor rope.

"Halloo, there!" shouted George.

Harriet paid no attention to the "halloo." Apparently she did not hear
them. George called again, and when Harriet turned and entered the
house, without having once glanced in George's direction, he grew red in
the face.

"She didn't hear you," chuckled Larry. "You didn't yell loudly enough.
Why didn't you let me give them a roar? I'll guarantee to attract the
attention of any one within half a mile of me."

"Run alongside, Billy. I'm going to make somebody notice me."

George blinked rapidly. The boys glanced at each other and looked
perplexed and uneasy. Somehow, they had a feeling that they were being
placed in an unenviable light.

"The question is, where have you been?" asked George in as gruff a tone
as he could assume.

"Where have we been?" repeated Harriet wonderingly. "Are you joking, Mr.
Baker?"

"No, I'm not joking. We have been worried about you. Where have you
been?"

"Why, we have been not far from here all the time. And you mean to tell
me that you didn't know where we were?"

George shook his head. His companions looked sheepish.

"Did you sail over here so early in the morning to call on us?"
questioned Harriet innocently.

"No, we are camping over there."

"Oh! Then you ca
