Mt. Pilchuck in the state of Washington is comparatively unfamiliar territory outside the Northwest, and the interest in this book will be largely regional. It is the record of exploration of three men,- ""Doc "" the ecologist, whose project was to study animal and plant life; Frank, the narrator, whose interest was in conservation; and Merle, the practical woodsman. The reader follows closely the way in which they worked, the forms of life on the mountain they observed, -- food, habits, favorable and unfavorable conditions, where found, varying types. The scientific data is reported elsewhere; this is the personal record, descriptive of the beauty of the mountain, a feeling of the ordered pattern of life, discussions of the trio on a multitude of topics. Readable- but special.
