The statements and arguments contained in these Notes might have been supported by reference to numerous authorities; but, though the writer wished, for his own sake, to adopt that course, still he was afraid that, by doing so, he might render his work too formal. To one book, however, he has referred pretty often; Mr. Stuart's Three Years in North America; a production, which may be termed a storehouse of facts concerning the United States. If Mr. Stuart had seen fit to develope the causes of the facts which he has collected, to give reasons for the chief social peculiarities of America, these Notes, or at least such of them as treat directly of the United States, would not have been published.
