See how the moralistic note is struck in the field of political satire. It is 1866, and "Petroleum V. Nasby," writing from "Confedrit X Roads," Kentucky, gives Deekin Pogram's views on education. "He didn't bleeve in edjucashun, generally speekin. The common people was better off without it, ez edjucashun hed a tendency to unsettle their minds. He had seen the evil effex ov it in niggers and poor whites. So soon ez a nigger masters the spellin book and gits into noosepapers, he becomes dissatisfied with his condishin, and hankers after a better cabin and more wages. He towunst begins to insist onto ownin land hisself, and givin his children edjucashun, and, ez a nigger, for our purposes, aint worth a soo markee." The single phrase, "ez a nigger," spells a whole chapter of American history. That quotation from "Petroleum V. Nasby" serves also to illustrate a species of American humor which has been of immense historical importance and which has never been more active than it is to-day: the humor, namely, of local, provincial, and sectional types. Much of this falls under Bergson's conception of humor as social censure. It rebukes the extravagance, the rigidity, the unawareness of the individual who fails to adapt himself to his social environment. It takes the place, in our categories of humor, of those types of class humor and satire in which European literature is so rich. The mobility of our population, the constant shifting of professions and callings, has prevented our developing fixed class types of humor. We have not even the lieutenant or the policeman as permanent members of our humorous stock company. The policeman of to-day may be mayor or governor to-morrow. The lieutenant may go back to his grocery wagon or on to his department store. But whenever and wherever such an individual fails to adapt himself to his new companions, fails to take on, as it were, the colors of his new environment, to speak in the new social accents, to follow the recognized patterns of behavior, then the kindly whip of the humorist is already cracking round his ears. The humor and satire of college undergraduate journalism turns mainly upon the recognized ability or inability of different individuals to adapt themselves to their changing pigeon-holes in the college organism. A freshman must behave like a freshman, or he is laughed at. Yet he must not behave as if he were nothing but the automaton of a freshman, or he will be laughed at more merrily still.
