going of the people and carriages and automobiles, and when he blew his whistle the traffic would go up and down one street, and then when he blew his whistle again it would go up and down the other.
The policeman had just blown on his whistle, and the traffic was going past the Bobbsey twins when Freddie gave a sudden loud blow. Immediately some of the carriages and automobiles going in one direction stopped short and the others commenced to go the other way.
"For gracious sake, Freddie! see what you have done," gasped Bert.
The traffic policeman who stood in the middle of the two streets looked very much surprised. Then he saw it was Freddie who had blown the whistle, and he shook his finger at the little boy in warning.
"He wants you to stop," said Nan, and made Freddie put the whistle in his pocket for the time being.
Then the Bobbseys and their friends hurried on their way.
"I'll give you the fifteen cents as soon as we get back to the hotel, Billy," said Bert.
