Mark Twain ransacked the whole world of his own day, all countries, savage and civilized, for the display of effective and ludicrous contrast; and he opened up an illimitable field for humanizing satire, as Mr. Howells has said, in his juxtaposition of sociologic types thirteen centuries apart. Not even heaven was safe from the comprehensive survey of his satire; and 'Captain Stormfield's Visit to Heaven' is a remarkable document,--a forthright lay sermon,--the conventional idea of heaven, the theologic conception of eternity, as heedlessly taught from the pulpit, thrown into comic, yet profoundly significant, relief against the background of the common-sense of a deeply human, thoroughly modern intelligence. Humour, as Thackeray has defined it, is a combination of wit and love. Certain it is that, in the case of Mark Twain, wit was a later development of his humour; the love was there all the time. Mark Twain has not been recognized as a wit; for he was primarily a humorist, and only secondarily a wit. But the passion for brief and pungent formulation of an idea grew upon him; and Pudd'nhead Wilson's Calendar is a mine of homely and memorable aphorism, epigram, injunction. According to Mark Twain's classification, the comic story is English, the witty story French, the humorous story American. While the other two depend upon matter, the humorous story depends for its effect upon the manner of telling. The witty story and the comic story must be concise and end with a “point”; but the humorous story may be as leisurely as you please and have no particular destination. Mark Twain always maintained that, while anyone could tell effectively a comic or a witty story, it required a person skilled in an art of a rare and distinctive character to tell a humorous story successfully. Mark Twain was himself the supreme exemplar of the art of telling a humorous story. Take this little passage, for example, which convulsed one of his London audiences. He was speaking of a high mountain that he had come across in his travels. “It is so cold that people who have been there find it impossible to speak the truth; I know that's a fact (here a pause, a blank stare, a shake of the head, a little stroll across the platform, a sigh, a puff, a smothered groan), because--I've--(another pause)--been --(a longer pause)--there myself.” Who could equal Mark Twain as a humorous narrator, in his recital of the alarums and excursions, criminations and recriminations, over the story of somebody else's dog he sold to General Miles for three dollars? He delighted numerous audiences with his story of inveighing Mrs. Grover Cleveland at a White House reception into writing blindly on the back of a card “He didn't.” When she turned it over she discovered that it bore on the other side, in Mrs. Clemens' handwriting, the startling words: “Don't wear your arctics in the White House.” I shall never forget his recital of the
