"Certainly our ideas of what is funny have changed," he said. "Humor is an ephemeral thing. A generation ago we laughed at what to-day would merely make us ill. The subjects and the methods of the humorists are different. Who nowadays can find a laugh in the pages of Artemus Ward, Philander Q. Doesticks, or Petroleum V. Nasby? Yet in their time these men set the whole continent in a roar.
"Contrast two humorists typical of their respective periods—Bill Nye and Abe Martin. I remember many years ago reading a story by Bill Nye which every one then considered tremendously funny. He told how he went downtown and got a shave and put on a clean collar and as he said, 'otherwise disguised himself.' When he got home his little dog refused to recognize him, and several pages were devoted to his efforts to persuade the dog of his identity. Then, failing to convince the dog that he was really the same Bill Nye in spite of his shave and clean collar, he impaled it on a pitchfork and buried it, putting over it the epitaph, 'Not dead, but jerked hence by request.'
"Now contrast with that a good example of modern American humor—a joke by Abe Martin which I recently saw. There was a picture of two or three men looking at a tattered tramp, and one of them was represented as saying: 'You wouldn't think to look at him that that man played an elegant game of billiards ten years ago!'
"It is an entirely different form of humor, you see. Bill Nye and the writers of his school got their effects by grotesque misspelling, fantastic ideas, and by the liberal use of shock and surprise. The modern humor is subtler, more delicate, and more likely to endure.
"I do not think that the fact that America has become more cosmopolitan has anything to do with this altered sense of humor. The American humorists do not select cosmopolitan themes; the best of them are distinctively American in their subject. Irvin Cobb, George Fitch, Kate Douglas Wiggin, Edna Ferber Stewart, who wrote The Fugitive Blacksmith—all these people draw their inspiration from purely American phases of the life around them."
"What is it, then," I asked, "that has changed American humor?"
"Leisure," answered Mr. Glass. "Philander Q. Doesticks and other humorists of his time wrote to amuse pioneers, people rough and elemental in their tastes. Their audience consisted of men who worked hard most of the time, and therefore had to be hit hard by any joke that was to entertain them at all. But as Americans grew more leisurely, and therefore had time to read, see plays, and look at pictures, they lost their taste for crude and violent horseplay, and the new sort of humor came in. Undoubtedly the same thing occurs in every newly settled country—Australia, for example. It is unlikely that the Australian of one hundred years from now will be amused by the things that amuse Australians to-day.
"But the humor that entertains the citizens of a country of which the civilization is well established is likely to retain its charm through the years. Mark Twain's stories do not lose their flavor. But Mark Twain was not exclusively a humorist; he was a student of life and he reflected the tragedy of existence as well as its comedy. So does Irvin Cobb, who is the nearest approach to Mark Twain now living.
"One source of Mark Twain's strength is his occasional vulgarity. That surely is something that we should have in greater abundance in American humor. I do not mean that our humorists should be pornographic and obscene; I mean merely that they should be allowed great freedom in their choice of themes. There is no humor without vulgarity. Our humorists have been so limited and restrained that we have no paper fit to be compared with Simplicissimus or Le Rire.
"You see, a vulgar thing is not offensive if it is funny. Fun for fun's sake is a much more important maxim than art for art's sake. The humorists have a greater need for freedom in choice of themes than the serious writers, especially the realistic writers, who are always demanding greater freedom."
