Book Description
Encompassing the Boundary Waters Canoe Area of Superior National Forest, Voyageurs National Park, and Grand Portage National Monument in Minnesota and Quetico Provincial Park in Ontario, the Quetico-Superior is the only region of its kind in the U.S. and Canada. This book tells the story of the long campaign to secure and preserve it for posterity and also illustrates the development of an American idea -- wilderness preservation.

Book Description
Balsam Fir was first published in 1965. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Professors Bakuzis and Hansen, with the assistance of a number of co-authors of individual chapters, present an exhaustive survey of the literature on the balsam fir, providing a coherent picture of the species and its place in nature and forestry practice. The balsam fir is used extensively in the pulp and paper industry, and it is known to millions as a traditional Christmas tree. In North America it is a major tree species in Canada, in the northeastern United States, and in the Great Lakes region. In the search of the literature, over 2000 sources were consulted and considerably more than half of them are cited in the book. The references, organized in an ecological framework, cover the period from the seventeenth century to the present. The authors have reviewed and integrated these data in a unified, but multipurposed, book. In the integration of the source material the authors also made contributions of their own. The book contains the following chapters: Botanical Foundations, Geography and Synecology, Ecological Factors, Microbiology, Entomology, Reproduction, Stand Development, Growth and Yield, and Utilization. Appendixes list fungi and myxomycetes and insects associated with balsam fir. There are 30 illustrations, including a frontispiece drawing by the noted nature artist Francis Lee Jaques. The book will appeal to a wide range of readers specifically concerned with forestry, including research workers, educators, entomologists, pathologists, and managing foresters, as well as conservationists and wildlife biologist in general.

Book Description
A wordless picture-book journey through the Boundary Waters, canoeing and camping with a family as they encounter the northwoods wilderness in all its spectacular beauty It's a place of wordless wonder: the wilderness of the Boundary Waters on the Minnesota-Canada border. Travel its vast distances, canoe its streams and glacial lakes, take shelter from rain under a rocky outcropping (or in your tent), camp in its vaulting forests as stars embroider the darkening sky. Is this your first visit? Or is it already your favorite destination? Come along--join a family of three as their journey unfolds, picture by picture, marking the changing light as the day passes, the stillness before the gathering storm, the shining waters everywhere, rushing here, quietly pooling there, beckoning us ever onward into nature's infinite wildness one summer up north.

Book Description
S2Work carried out by the Northeastern Forest Experiment Station in West Virginia in the past 12 years provides useful information about the relationships between tree d.b.h. and butt-log grade. The upper logs are not included in the relationships. Being smaller and containing more knots, these upper logs are generally of lower grade than the butt logs. Thus the average grade of all material in the sawlog portion of the tree is generally lower than the average grade of the butt log. In the West Virginia data, species differences in d.b.h.-grade relationship are readily apparent. This inherent tendency for species to have different proportions of the various grades in logs of the same size is a familiar phenomenon to grade-conscious foresters who work with hardwoods. The results in this paper provide a quantitative evaluation of this tendency for six of the local species.S3.

Book Description
To do with the calling of loons, with northern lights, and the great silences of land lying northwest of Lake Superior. It is concerned with the simple joys, the timelessness and perspective found in a way of life which is close to the past. I have heard the singing in many places, but I seem to hear it best in the wilderness lake country of the Quetico-Superior, where travel is still by pack and canoe over the ancient trails of the Indians and voyageurs." Thus the author sets the theme and tone of this enthralling book of discovery about one of the few great primitive areas in our country which have withstood the pressures of civilization. Acute natural perceptivity and a profound knowledge of the relationships to be found in nature combine here in vivid evocations of the sights, the sounds, the vast stillnesses, and the events of the wilderness as the seasons succeed each other. But Mr. Olson is not content merely to "describe; he probes for meanings that will lead the reader to a different and more revealing way of looking at the out-of-doors and to a deeper sense of its eternal values. In each of the thirty-four chapters of The Singing Wilderness he has sought to capture an essential quality of our magnificent lake and forest heritage. He shows us what can be read from the rocks of the great Canadian Shield; he offers a delightful essay on the virtues of pine knots as fuel; he writes of the ways of a canoe, of flashing trout in the pools of the Isabella, of tamarack bogs, caribou moss, the flight of wild geese, timber wolves, and the birds of the ski trails. And much more, with something to satisfy every taste for wilderness experience. Superbly illustrated with 38 black-and-white drawings by Francis Lee Jaques, The Singing Wilderness is a book that no lover of nature will want to be without. To anyone who contemplates a vacation in the lake country of northern Minnesota and adjoining Canada, it is the perfect vade mecum.
