The topical method however may also be pushed too far. Each successive stage of any topic can be understood only in relation to the forces of the time. For that reason the best results are reached when there is a combination of the chronological and the topical methods. It is therefore suggested that the teacher first follow the text closely and then review the subject with the aid of this topical syllabus. The references are to pages. Immigration I.
