MOUNTAINS ON THE MOVE

There is no better way to achieve a sense of vast time than by studying the history of topography. In this text, illustrated with photographs, the author discusses the changes that have taken place in this country, the formation of mountains, the drainage of seas, and the accompanying changes in plant and animal life. While concentrating on the scientific aspects of the subject, Marie Bloch manages to impart a sense of drama to the study she makes of the slow but infinite fluctuations of nature. A book for home and school use, Mountains on the Move is valuable both for the specific information it imparts and the broadening of perspective it encourages.
