A Traveller from Altruria - William Dean Howells

Set in the early 1890s, at a fashionable summer resort somewhere on the East Coast of the United States, this book tells the story of Mr. Twelvemough, an author who has been selected to function as host to a visitor from the faraway island of Altruria. The visitor, Mr. Homos, has come all the way to the United States, a country which prides itself on democracy and equality, to experience everyday life in America firsthand, and to see for himself how the principle that "All men are created equal" is being put into practice. Due to Altruria's secluded existence, very little is known about the island, so Twelvemough and his circle of acquaintances, all of whom are staying at the same resort hotel, seem more eager to learn about Altruria than to explain American life and institutions. To their dismay, it becomes gradually clear that the United States is greatly lagging behind Altruria in practically every aspect of life, be it political, economic, cultural or moral.
