orthography, he pronounces that "Chaucer was a great poet but he couldn't spell," or where he says of the feast of raw dog, tendered him by the Indian chief, Wocky-bocky, "It don't agree with me. I prefer simple food." On the whole, it may be said of original humor of this kind, as of other forms of originality in literature, that the elements of it are old, but their combinations are novel. Other humorists, like Henry W. Shaw ("Josh Billings") and David R. Locke ("Petroleum V. Nasby"), have used bad spelling as a part of their machinery; while Robert H. Newell ("Orpheus C. Kerr"), Samuel L. Clemens ("Mark Twain"), and more recently "Bill Nye," though belonging to the same school of low or broad comedy, have discarded cacography. Of these the most eminent, by all odds, is Mark Twain, who has probably made more people laugh than any other living writer. A Missourian by birth (1835), he served the usual apprenticeship at type-setting and editing country newspapers; spent seven years as a pilot on a Mississippi steam-boat, and seven years more mining and journalizing in Nevada, where he conducted the Virginia City _Enterprise_; finally drifted to San Francisco, and was associated with Bret Harte on the _Californian_, and in 1867 published his first book, _The Jumping Frog_. This was succeeded by the _Innocents Abroad_, 1869; _Roughing It_, 1872; _A Tramp Abroad_, 1880, and by others not so good. Mark Twain's drolleries have frequently the same air of innocence and surprise as Artemus Ward's, and there is a like suddenness in his turns of expression, as where he speaks of "the calm confidence of a Christian with four aces." If he did not originate, he at any rate employed very effectively that now familiar device of the newspaper "funny man," of putting a painful situation euphemistically, as when he says of a man who was hanged, that he "received injuries which terminated in his death." He uses to the full extent the American humorist's favorite resources of exaggeration and irreverence. An instance of the former quality may be seen in his famous description of a dog chasing a coyote, in _Roughing It_, or in his interview with the lightning-rod agent in Mark Twain's _Sketches_, 1875. He is a shrewd observer, and his humor has a more satirical side than Artemus Ward's, sometimes passing into downright denunciation. He delights particularly in ridiculing sentimental humbug and moralizing cant. He runs atilt, as has been said, at "copy-book texts," at the temperance reformer, the tract distributer, the Good Boy of Sunday-school literature, and the women who send bouquets and sympathetic letters to interesting criminals. He gives a ludicrous turn to famous historical anecdotes, such as the story of George Washington and his little hatchet; burlesques the time-honored adventure, in nautical romances, of the starving crew casting lots in the long-boat, and spoils the dignity of antiquity by modern trivialities, saying of a discontented
