That it provides a serious mental discipline will, it is hoped, be apparent to any one who cares to read the following pages. A discussion of the science of geographical investigation, here presented with particular respect to the study of land forms, but equally applicable to other divisions of the subject, will show that geography, like various other sciences, gives abundant exercise to various mental faculties, such as observation, invention, deduction, comparison and judgment; while a consideration of the art of geographical presentation will show that geography, like other sciences, encourages the development of various styles of composition, such as narrative, inductive, analytical, systematic and regional, each of which is particularly well adapted to the exposition of certain geographical problems.

The Student and the World.—It has been well remarked by an experienced university professor, that an advanced student would profit
