It has been justly objected to school-books, written in the form of question and answer, that, as they may be completely learned by an unintelligent exercise of memory, they fail in drawing forth the more active powers of the mind. It is far otherwise with questions to which the pupil must find the answers for himself; as, by this mode of interrogation he is compelled to exert his intellect in considering the subject of the text on which he is questioned. He is thus prevented from reading cursorily and remembering vaguely; he can no longer have the appearance of knowledge without its reality; and if he learns his lesson at all, he must learn it well. This book consists of several thousand questions, with indications of the pages where the answers are to be looked for. Every important circumstance mentioned in the history is involved in the questions, which are arranged, as far as possible, in a complete and uninterrupted series. The answers are not always obvious, the learner being occasionally expected to elicit them by drawing inferences from the facts stated in the history; and it is recommended that he should be encouraged, in all cases, to give the answers rather in his own words than in those of the author.
