One special object which the author of this series has had in view, in the plan and method which he has followed in the preparation of the successive volumes, has been to adapt them to the purposes of text-books in schools. The study of a general compend of history, such as is frequently used as a text-book, is highly useful, if it comes in at the right stage of education, when the mind is sufficiently matured, and has acquired sufficient preliminary knowledge to understand and appreciate so condensed a generalization as a summary of the whole history of a nation contained in an ordinary volume must necessarily be.
