"Come," said Fred, taking the young lady's arm, and the two quickly made their way out of the mob, which, balked of its prey, howled in futile rage.
"I live here," said the young lady, stopping before a palatial residence. "My name is Mabel Vaughn. You must come in and let my mother thank you. How brave you were, and Policeman Green, too. How can I thank you both enough for what you did!"
"You must excuse me now," replied Fred, politely raising his hat; "but to-morrow, if possible, I will call, and see if you have experienced any ill effects from the rough treatment you have received. But I must go now, for I may be of some further use," and with a bow, Fred was gone.
"If he were only older, I would have a mind to throw Bob overboard," said the young lady to herself, as she entered the house.
Going back to the scene of his adventure, Fred found that a great crowd had gathered around the place where he had knocked the ruffian down.
"What is this?" yelled Tompkins, coming up at the head of a multitude of followers.
"Shure," cried an Irish voice, "Big Jim is kilt intoirely, intoirely."
"Who did it?" demanded Tompkins, with an oath. No one knew. By this time Big Jim, with the aid of two companions, had staggered to his feet, and was looking around in a dazed condition.
"He will come around all right," said Tompkins. "To the City Hall, boys. Down with the rag floating there! Down with the city officials; let's throw them into the Ohio," and with frightful cries, the mob started for the city hall.
