Bobby Bright and Harry West, whose histories were contained in the last two volumes of the "Library for Young Folks," were both smart boys. The author, very grateful for the genial welcome extended to these young gentlemen, begs leave to introduce to his juvenile friends a smart girl,—Miss Katy Redburn,—whose fortunes, he hopes, will prove sufficiently interesting to secure their attention.  
If any of my adult readers are disposed to accuse me of being a little extravagant, I fear I shall have to let the case go by default; but I shall plead, in extenuation, that I have tried to be reasonable, even where a few grains of the romantic element were introduced; for Baron Munchausen and Sindbad the Sailor were standard works on my shelf in boyhood, and I may possibly have imbibed some of their peculiar spirit. But I feel a lively satisfaction in the reflection that, whatever exaggerations the critic may decide I have perpetrated in this volume, I have made the success of Katy Redburn depend upon her good principles, her politeness, her determined perseverance, and her overcoming that foolish pride which is a snare to the feet. In these respects she is a worthy exemplar for the young.
 
Pride and poverty do not seem to agree with each other; but there is a pride which is not irreconcilable with the humblest station. This pride of character finds an illustration in the life of my heroine.
 
Thanking my young friends again for the pleasant reception given to my former books I submit this volume in the hope that Katy Redburn will prove to be a worthy and agreeable companion for their leisure hours.
