This book was released on 1985 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic salmon (Salmo salar) has occupied a salient position in the history of eastern North America for at least the past 1000 years. Initially the species occupied a prominant niche in the prolific web of life that existed throughout its former occurrence area; millions of pounds of salmon were produced annually from the freshwater streams between New York and Ungava - a resource that was a principal food source for the Amerindian cultures which shared its range. In a chronological and cumulative way, the salmon became an increasingly important factor in both the domestic and commercial life of the developing colonies; it provided a recreational outlet for the sportsman, and evolved as a principal object of intellectual and scientific investigation. The documented specifics of the salmon's history, however, are largely comprised of repetitive instances of overexploitation, careless destruction of stocks and their environment, and ineffectual conservation actions. Despite the species' former importance, its more recent history is one of declining presence, and its destiny appears to be extinction. By documenting this story of discovery, exploitation, and decline, the urgent need for the employment of sound resource management practices to preserve the salmon is emphasized. Appendix A: Historical methods of packing salmon.

Download or read book Early Life in Upper Canada written by Edwin C. Guillet and published by University of Toronto Press. This book was released on 1933-12-15 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there were abundant hardships, early life in Upper Canada was romantic and colourful in many ways. However, despite important contributions to the social and economic history of Canada, few good, comprehensive accounts have been generally available. Early Life in Upper Canada, originally published in 1933, is by far the finest history yet compiled, and it is now being reprinted in order to make available to a new generation an important and engrossing description of this area of Canadian history. The author, a distinguished Canadian historian, has drawn on contemporary letters, diaries, newspapers, and periodicals, as well as consulting all the existing histories, and he has supplemented these researches with interviews with persons who had personal contacts with early life in the Province. Mr. Guillet has compiled a thorough, accurate and delightfully readable history, that brings vividly to life the early settlers and their experiences. This is in accordance with the author's profound desire to make the study of Canadian history a delight rather than a chore. He has not concealed the unpleasant aspects of pioneer life, nor does he attempt to glamorize its difficulties. There is a tendency at times to forget that the founders of Upper Canada include hundreds of thousands of men and women of many nationalities, and fur traders, lumbermen, and voyageurs, as well as settlers. Their contributions, too, are acknowledged and recorded here. This book is profusely illustrated, with drawings made, in many cases, by army cartographers, who were skilled creative artists as well. Their paintings, fortunately, have been better preserved than were written accounts of the times, and are accurate depictions of pioneer life. The extensive bibliography and carefully prepared index will make this work invaluable for historians as well as for general readers.
