This book is appropriately mentioned in these columns for the fact that it provides valuable help to those glaciologists who intend doing research work on snow mountains and glaciers but may not be experienced alpinists. Three excellent chapters are devoted to this aspect of the subject. Translated from the Swiss Bergsteigen by a panel of expert British mountaineers it speaks with double authority and is strongly recommended for the soundness of its approach and its clarity, not only to those mentioned above but to all who intend wandering or climbing in the mountains.
