Book Description
The fascinating story of a trial that opened a window onto the century-long battle to control nature in the national parks. When twenty-five-year-old Harry Walker was killed by a bear in Yellowstone Park in 1972, the civil trial prompted by his death became a proxy for bigger questions about American wilderness management that had been boiling for a century. At immediate issue was whether the Park Service should have done more to keep bears away from humans, but what was revealed as the trial unfolded was just how fruitless our efforts to regulate nature in the parks had always been. The proceedings drew to the witness stand some of the most important figures in twentieth century wilderness management, including the eminent zoologist A. Starker Leopold, who had produced a landmark conservationist document in the 1950s, and all-American twin researchers John and Frank Craighead, who ran groundbreaking bear studies at Yellowstone. Their testimony would help decide whether the government owed the Walker family restitution for Harry's death, but it would also illuminate decades of patchwork efforts to preserve an idea of nature that had never existed in the first place. In this remarkable excavation of American environmental history, nature writer and former park ranger Jordan Fisher Smith uses Harry Walker's story to tell the larger narrative of the futile, sometimes fatal, attempts to remake wilderness in the name of preserving it. Tracing a course from the founding of the national parks through the tangled twentieth-century growth of the conservationist movement, Smith gives the lie to the portrayal of national parks as Edenic wonderlands unspoiled until the arrival of Europeans, and shows how virtually every attempt to manage nature in the parks has only created cascading effects that require even more management. Moving across time and between Yellowstone, Yosemite, and Glacier national parks, Engineering Eden shows how efforts at wilderness management have always been undone by one fundamental problem--that the idea of what is "wild" dissolves as soon as we begin to examine it, leaving us with little framework to say what wilderness should look like and which human interventions are acceptable in trying to preserve it. In the tradition of John McPhee's The Control of Nature and Alan Burdick's Out of Eden, Jordan Fisher Smith has produced a powerful work of popular science and environmental history, grappling with critical issues that we have even now yet to resolve.

Book Description
An in-depth exploration of the effects of different steels, heat treatments, and edge geometries on knife performance. This book provides ratings for toughness, edge retention, and corrosion resistance for all of the popular knife steels. Micrographs of over 50 steels. Specific recommended heat treatments for each steel. And answers to questions like: 1) Does a thinner or thicker edge last longer? 2) What heat treatment leads to the best performance? 3) Are there performance benefits to forging blades? 4) Should I use stainless or carbon steel? All of these questions and more are answered by a metallurgist who grew up around the knife industry.

Book Description
Why has the American South--a place with abundant rainfall--become embroiled in intrastate wars over water? Why did unpredictable flooding come to characterize southern waterways, and how did a region that seemed so rich in this all-important resource become derailed by drought and the regional squabbling that has tormented the arid American West? To answer these questions, policy expert and historian Christopher Manganiello moves beyond the well-known accounts of flooding in the Mississippi Valley and irrigation in the West to reveal the contested history of southern water. From the New South to the Sun Belt eras, private corporations, public utilities, and political actors made a region-defining trade-off: The South would have cheap energy, but it would be accompanied by persistent water insecurity. Manganiello's compelling environmental history recounts stories of the people and institutions that shaped this exchange and reveals how the use of water and power in the South has been challenged by competition, customers, constituents, and above all, nature itself.

Book Description
The history of Charlotte is inseparable from the history of its neighborhoods. From the city's founding until the late 1890s, the four wards created by the crossing of Trade and Tryon Streets defined the residential fabric of Charlotte. As the twentieth century approached, the Southern textile boom fueled labor and housing demands that were met by the earliest suburbs that rose out of the farms and pastures surrounding the small town. Dilworth was the first of these suburbs, connected to the town center by the city's maiden electric streetcar line. More new communities quickly followed. Some, such as Myers Park and Elizabeth, have remained strong throughout their history. North Charlotte, Belmont, and others have changed under economic and social challenges. Still others, such as Brooklyn, are gone; they survive only in the memories and photographs of the families that called them home.
