American society is mixed--heterogeneous--more so, probably, than that of any other country. There is no such thing as well-defined classification. There is no nobility, no gentry, no aristocracy, no peasantry. The owners of palaces were bred in log cabins; men of learning are the children of boors; and one can never tell by a man's position and relations in society into what style of life he was born. The boy goes into the city from his father's farm, carrying only a hardy frame, a good heart, and a suit of homespun, and twenty years frequently suffice to establish him as a man of fortune, and marry him to a woman of fashion. There is no bar to progress in any direction for the ambitious man, except lack of brains and tact. Society erects no barriers of caste which define the bounds of his liberty. Notwithstanding this, there is always, in every place, a body of people who assume to be "the best society." The claim to the title is rarely well substantiated, and is based on different ideas in different places. We shall find in some places, that society crystallizes around the idea of wealth; in others, around the idea of literary culture; in others, around certain religious views, so that, as it may happen, the "best society" is constituted of the Presbyterian, or Episcopalian, or Unitarian, or other sectarian element. In other places, an old family name is the central power, and, in others still, a certain style of family life attracts sympathetic materials which assume the position of "the best society."
