The Strange Adventures of a Pebble

The relation of this book to the formal study of physiography or geology in the schools will be apparent. The classified and exhaustive treatment of the text-book, while so admirably adapted to organize knowledge already acquired, or reward an appetite already aroused, is not at all adapted for creating this appetite in the first place; a thing so essential to true progress in education.

For example, in a text-book, the many aspects of glaciers and their work, which are here distributed in a number of sections (as the discovery of these aspects was distributed in time), are usually dealt with in a single chapter or series of chapters, whose nature the reader at once gathers from the title, "The Work of the Glaciers."
