The incompatibility existing between European and American views of life, which makes the comedy or the tragedy of Henry James's international fictions, is replaced in Howells's novels by the repulsion between differing social grades in the same country. The adjustment of these subtle distinctions forms a part of the problem of life in all complicated societies. Thus in _A Chance Acquaintance_ the heroine is a bright and pretty Western girl, who becomes engaged during a pleasure tour to an irreproachable but offensively priggish young gentleman from Boston, and the engagement is broken by her in consequence of an unintended slight--the betrayal on the hero's part of a shade of mortification when he and his betrothed are suddenly brought into the presence of some fashionable ladies belonging to his own _monde_. The little comedy, _Out of the Question_, deals with this same adjustment of social scales; and in many of Howells's other novels, such as _Silas Lapham_ and the _Lady of the Aroustook_, one of the main motives may be described to be the contact of the man who eats with his fork with the man who eats with his knife, and the shock thereby ensuing. In _Indian Summer_ the complications arise from the difference in age between the hero and heroine, and not from a difference in station or social antecedents. In all of these fictions the misunderstandings come from an incompatibility of manners rather than of character, and, if any thing were to be objected to the probability of the story, it is that the climax hinges on delicacies and subtleties which, in real life, when there is opportunity for explanations, are readily brushed aside. But in _A Modern Instance_ Howells touched the deeper springs of action. In this, his strongest work, the catastrophe is brought about, as in George Eliot's great novels, by the reaction of characters upon one another, and the story is realistic in a higher sense than any mere study of manners can be. His nearest approach to romance is in _The Undiscovered Country_, 1880, which deals with the Spiritualists and the Shakers, and in its study of problems that hover on the borders of the supernatural, in its out-of-the-way personages and adventures, and in a certain ideal poetic flavor about the whole book, has a strong resemblance to Hawthorne, especially to Hawthorne in the _Blithedale Romance_, where he comes closer to common ground with other romancers. It is interesting to compare the _Undiscovered Country_ with Henry James's _Bostonians_, the latest and one of the cleverest of his fictions, which is likewise a study of the clairvoyants, mediums, woman's rights advocates, and all varieties of cranks, reformers, and patrons of "causes," for whom Boston has long been notorious. A most unlovely race of people they become under the cold scrutiny of Mr. James's cosmopolitan eyes, which see more clearly the charlatanism, narrow-mindedness, mistaken fanaticism, morbid self-consciousness, disagreeable nervous intensity, and vulgar or ridiculous outside peculiarities of the humanitarians, than the nobility and moral enthusiasm which underlie the surface.
