After all, there really was not so much danger. Mr. Bobbsey had taught Flossie some of the things one must do when learning to swim, and that is to hold your breath when you are under water. For it is the water getting into the lungs that causes a person to drown. After her first plunge into the creek, the little girl thought of what her father had told her, and did hold her breath.

"I--I'll get you!" called Harry to her. "Don't be afraid, Flossie!

I'll get you!"

Flossie was too much out of breath to answer, so she did not try to speak. Harry was soon at her side, and called to her:

"Now put your hands on my shoulders, Flossie, and I'll swim to the boat with you. Don't try to grab me around the neck."

Harry knew how dangerous it was for a person trying to rescue another in the water to be choked. Flossie was a wise little girl, even if she was not very old. She did as her cousin told her, and, with Flossie's hands on his shoulders, Harry began to swim toward the Bluebird.

He did not have to go very far, though, for by this time Mr. Bobbsey and Captain White were there with the rowboat, and the two children were soon lifted in. They were safe, and not harmed a bit, except for being wet through.

"Oh, Flossie, whatever did you do it for?" asked her mother, when she had hugged the dripping little girl in her arms. "Why did you do it?"

"Do what, mamma?" Flossie asked.

"Lean over so far."

"I wanted to see if I had a fish," went on Flossie. "And I had to lean over. And then I saw him."

"Saw whom?" asked her father. "What do you mean?"

"Why, I saw him--that boy," and Flossie seemed surprised that her father did not understand.

"What boy?" asked Mrs. Bobbsey. "Did you fall asleep there, Flossie, and were you dreaming, when you fell in?"

"No, mamma. I didn't fall asleep. I saw HIM, I tell you."

"I heard her say something about seeing some one, just as she went over the rail, head first," Dorothy said.

"But whom do you mean, Flossie?" asked puzzled Mrs. Bobbsey.

"Why, that boy--the one the bad man whipped."

"Oh, Will Watson!" exclaimed Bert. "Where did you see him, Flossie?

Was he in one of the excursion boats that went past?"

"No, he was on our boat--down there," and Flossie pointed straight down. "I saw him!" she declared.

"I guess she must have dozed off a little, and dreamed it," spoke Mr.

Bobbsey, with a smile. "That was it. The sun was so hot, that she just slept a little as she was fishing. She might have had a bite, and that awakened her so suddenly that she gave a jump and fell over the rail.

I must have it built higher. Then there won't be any danger."

"Yes, do," said Mrs. Bobbsey. "We've had scares enough."

"But I did see that boy--the one that gave Bert the fish," insisted Flossie. "He was on our boat. I saw him as plain as anything."

"It must have been some one in the excursion boats that looked like him," spoke Nan.

"No, I saw Will!" declared the little twin, and, rather than get her excited by disputing, they allowed her to think she really had seen a strange face, as she leaned over.

"But of course she either dreamed it, or saw some one she thought was that runaway boy," Mr. Bobbsey said, afterward. "It's all nonsense to think he was on our boat."

Snap, who had not been allowed to go to the rescue, much as he had wanted to, leaped about Flossie, barking and wagging his tail in joy.

"Anybody would think he'd done it all," said Bert. "Say, Harry, you're all right! That was a dandy dive!" and he clapped his cousin on the back.

"Indeed we never can thank you enough. Harry," said Mrs. Bobbsey, and tears of thankfulness glistened in her eyes.

"Oh, it wasn't anything at all," the country boy said, modestly blushing, for he did not like such a "fuss" made over him. "I knew I could get her out."

"Well, it was very fine of you," said Mr. Bobbsey, warmly. "Now then, you had better change your clothes, for, though it is summer, you might take cold. And Flossie, too, must change."

"Yes, I'll look after her," said her mother "Now remember, little fat fairy," Mrs. Bobbsey went on, giving Flossie her father's pet name, "you must never lean over the rail again. If you do---"

"But I saw---" began Flossie.

"No matter what you saw--don't lean over the rail!" said her mother.

"If you do, we shall have to give up this houseboat trip."

This seemed such a dreadful thing, that Flossie quickly promised to be very careful indeed.

"But I did see him, all the same!" she murmured, as her mother took her to the bedroom to change her clothes. "I saw that boy on our boat."

The others only laughed at Flossie for thinking such a queer thing.

"That poor boy is far enough away from here now," said Bert. "I wonder if he will really try to make his way out west?"

"I don't know," answered Harry, who had changed to a dry suit, hanging his other in the sun to let the water drip out of it. "I've read of boys making long journeys that way."

"I wouldn't want to try it," spoke Bert.

"Neither would I," said his cousin. "This houseboat suits me!"

Flossie was little the worse for her accident, and was soon playing about again with Snoop and Snap, and with Freddie. The little fellow and his sister made the dog and cat do many tricks.

It was the day after this, when the Bluebird had gone a little farther up the creek, that Mrs. Bobbsey planned a little picnic on sh.o.r.e. They were not far from a nice, green forest.

"We'll have Dinah put us up a little lunch, and we'll go in the woods and eat it," said Mrs. Bobbsey.

"Oh, that will be fun!" cried Nan. "Won't it, Dorothy?"

"Indeed it will," said the seash.o.r.e cousin.

"I'm going to take my doll," Flossie said. "There's no water in the woods for her to fall in, is there, mamma?"

"No, not unless you drop her into a spring," laughed Mrs. Bobbsey.
