It was the voice of the new West and of the new era. With _The Innocents Abroad_ begins the new period in American literature. The book is full of the new after-the-war Americanism that did its own thinking, that saw with its own eyes, that put a halo upon nothing save genuineness and substantial worth. It must not be forgotten that America even in the new seventies was still mawkish with sentimentality. The very year _The Innocents Abroad_ appeared, _Gates Ajar_ sold twenty editions. Mark Twain came into the age like the Goths into Rome. Stand on the solid earth, he cried. Look with your own eyes. Worship nothing but truth and genuineness. Europe is no better than America. Como is beautiful, but it is not so beautiful as Tahoe. Why this eternal glorification of things simply and solely because it is the conventional thing to glorify them? "The critic," he wrote in later years to Andrew Lang, "has actually imposed upon the world the superstition that a painting by Raphael is more valuable to the civilizations of the earth than is a chromo; and the august opera more than the hurdy gurdy and the villagers' singing society; and the Latin classics than Kipling's far-reaching bugle note; and Jonathan Edwards than the Salvation Army."[35] The new American democracy was speaking. To the man who for four years had learned in the school of Horace Bixby there was no high and no low save as measured, not by appearances or by tradition, but by intrinsic worth. IV It has been customary in libraries to place the earlier works of Mark Twain on the same shelf as those of Artemus Ward and Josh Billings. To the thousands who laughed at him as he lectured from year to year he was a mere maker of fun. The public that bought such enormous editions of _The Innocents Abroad_ and _Roughing It_ bought them as books to laugh over. What shall we say to-day of Mark Twain's humor? A generation has arisen to whom he is but a tradition and a set of books; what is the verdict of this generation? First of all, it is necessary that we examine the man himself. Nature seems to have forced him into the ranks of the comedians. From his mother he inherited a drawl that was inexpressibly funny; he had a laughable personality, and a laughable angle from which he looked at life. He could no more help provoking mirth than he could help being himself. Moreover, he had been thrown during his formative years into a veritable training school for humorists. On the river and in the mines and the raw towns and cities of the West, he had lived in a gale of high spirits, of loud laughter, of practical jokes, and droll stories that had gone the rough round of the boats or the camps. His humor, therefore, was an echo of the laughter of elemental men who have been flung into conditions full of incongruities and strange contrasts. It is the humor of exaggeration run wild, of youthful high spirits, of rough practical jokes, of understatement, of irreverence, and gross absurdity.
