"Did you look under the seats?" asked Bert.
"Under the seats!" exclaimed Billy. "What good would that do? Your brother and sister couldn't be under there!"
"Pooh, you don't know much about Flossie and Freddie!" answered Bert.
"They can be in more places than you can think of; can't they, Nan?"
"Yes, they do get into queer places sometimes. But they aren't under my seat," and Nan looked, to make sure.
"Nor mine," added Nell, as she looked also.
Some of the other passengers on the auto did the same thing. Mr. Bobbsey really thought it might be possible that Freddie and Flossie, for some queer reason, might have crawled under one of the seats when the big machine stopped for water. But the children were not there.
"Oh, what shall we do?" exclaimed Mrs. Bobbsey.
"They'll be all right," her husband answered. "They can't be far away."
"That's right ma'am," said a fat, jolly-looking man.
"Some of you go and inquire in the houses near here," suggested the man who drove the auto. "And I'll go and telephone back to the office, and see if they're there."
