It may interest the readers of this collection of tales, if there should be any such, to know that the incidents upon which the stories are based are unfortunately wholly truthful. They have one and all come under the author's observation during the past ten years, and with the exception of Mr. Bradley's Jewel, concerning whom it is expressly stated that she was employed through lack of other available material, not one of the servants herein made famous or infamous, as the case may be, was employed except upon presentation of references written by responsible persons that could properly have been given only to domestics of the most sterling character.
