As this work professes, in its title-page, to be a descriptive tale, they who will take the trouble to read it may be glad to know how much of its contents is literal fact, and how much is intended to represent a general picture. The author is very sensible that, had he confined himself to the latter, always the most effective, as it is the most valuable, mode of conveying knowledge of this nature, he would have made a far better book.
