Sketches by Mark Twain/Preface
PREFACE.
I have scattered through this volume a mass of matter which has never been in print before (such as "Learned Fables for Good Old Boys and Girls," the "Jumping Frog restored to the English tongue after martyrdom in the French," the "Membranous Croup" sketch, and many others which I need not specify): not doing this in order to make an advertisement of it, but because these things seemed instructive.
