Mrs. Bobbsey was just in time to see Freddie start his toy fire engine, and a little spray of water did shower over his twin sister.

“Freddie, stop it!” cried his mother. “You know you mustn’t do that!”

“I can’t help it,” Freddie said.

“Nonsense! You can’t help it? Of course you can help squirting water on your sister!”

“He can so!” pouted Flossie.

“No, Mother! I can’t, honest,” said Freddie. “The hose of my fire engine leaks, and that makes the water squirt out on Flossie. I didn’t mean to do it. I’m playing there’s a big fire and I have to put it out. And the hose busts—just like it does at real fires—and everybody gets all wet. I didn’t do it on purpose!”

“Oh, I thought you did,” said Flossie. “Well, if it’s just make believe I don’t mind. You can splash me some more, Freddie.”

“Oh, no he mustn’t!” said Mrs. Bobbsey, trying not to laugh, though she wanted to very much. “It’s all right to make believe you are putting out a fire, Freddie boy, but, after all, the water is really wet and Flossie is damp enough now. If you want to play you must fix your leaky hose.”

“All right, Mother, I will,” promised the little boy.

One corner of the room was his own special place to play with the toy fire engine. A piece of oil cloth had been spread down so water would not harm anything, and here Freddie had many good times.
