"The balloon will float on the water," her husband told her. "The children will be all right, I'm sure."
"Yes, indeed," agreed Mr. Trench. "Don't worry, lady. We'll get your children back. The first thing to do is to go to the lake, and then we can hire a motor-boat there."
"I'm going with you!" declared Mrs. Bobbsey, as she saw the preparations being made for the searching party.
"I think you had better stay with Bert and Nan," said Mr. Bobbsey.
"Oh, we'll be all right!" Nan hastened to tell her father.
"Can't Harry and I come on the searching party?" asked Bert.
"No, I would rather not," his father answered. "You stay with your mother and Nan."
"I simply am coming with you, Dick!" said Mrs. Bobbsey, and when she spoke in that tone her husband knew there was no use trying to get her to change her mind.
"Very well," agreed Mr. Bobbsey. "We will go to the lake in my auto. Mr. Trench knows where we can hire a motor-boat."
The lake, a large one, came within a few miles of the fair grounds. The balloon man knew in which direction the water lay, and he had seen the wind carrying the big gas bag toward the water.
