From the book:
Three young men stood together on a wharf one bright October day awaiting the arrival of an ocean steamer with an impatience which found a vent in lively skirmishes with a small lad, who pervaded the premises like a will-o'-the-wisp and afforded much amusement to the other groups assembled there. "They are the Campbells, waiting for their cousin, who has been abroad several years with her uncle, the doctor," whispered one lady to another as the handsomest of the young men touched his hat to her as he passed, lugging the boy, whom he had just rescued from a little expedition down among the piles.
