In starting out to set down the adventures and observations of "Pudd'nhead Wilson," Mark Twain had in mind the production of a short story, but "Pudd'nhead Wilson" refused to confine himself to the limits of a magazine sketch, and now he has become a large book, a part of which is a spirited farce called Those Extraordinary Twins. "Pudd'nhead Wilson" is one of the wittiest and most original characters Twain has produced. There was not in him the capacity to be grave, despite the solemnity of some of the positions in which he found himself. This curious volume is as full of the characteristic humor of Twain as is the best of his work. In this book he seems to have recovered much of his old-time spirit--spirit that has been conspicuous by its absence in a great deal of Twain's work printed during the past ten years. The artist that illustrates this work has a very keen sense of humor; indeed, his appreciation of the author's humor is greater than his skill as a draughtsman. The outline drawings are often crude, but there is humor in every line of them.
