While historians have given ample attention to stories of entrepreneurship, invention, and labor conflict, they have told us little about actual work-places and how people worked. Workers seldom wrote about their daily employment. However, they did leave behind their tools, products, shops, and factories as well as the surrounding industrial landscapes and communities. In this book, Gordon and Malone look at the industrialization of North America from the perspective of the industrial archaeologist. Using material evidence from such varied sites as Indian steatite quarries, automobile plants, and coal mines, they examine manufacturing technology, transportation systems, and the effects of industrialization on the land. Their research greatly expands our understanding of industry and focuses attention on the contributions of anonymous artisans whose skills shaped our industrial heritage.

Wetlands - swamp, marsh, bayou, tundra and bog - are places that are rarely visited and often misunderstood but they have, in fact, conspicuous roles in the physical, biological and cultural geography of the world. They are intrinsically beautiful environments where one may see the natural and essential values in the interaction of water, soil, vegetation, wildlife, and humans. Wetlands occur at the confluence of unique terrestrial, hydrological and climatic conditions that give rise to some of the most biodiverse regions of the world. They also play vital roles in the cycling and storage of key nutrients, materials and energy through the Earth?s system. A complete study of wetland environments requires the assessment of their physical and biological attributes, properties and functions of these ecosystems, and the economic, political and social aspects that mediate their use globally. A systems approach is taken throughout this book which emphasizes the interactions between these elements of wetland ecosystems. Moreover, selected case studies from across the world are used to illustrate wetland characteristics and circumstances. This book is intended to foster a greater awareness and appreciation of wetlands, promote a culture of conservation and wise management, and spread the knowledge that wetlands are important, indeed crucial, elements of the global environment. Our attempts to understand, manage and enhance wetlands in the twenty-first century are part of the larger effort to maintain a sustainable Earth. Readership: Introductory or intermediate level undergraduates taking courses on wetland environments Additional resources for this book can be found at: www.wiley.com/go/aber/wetland

Ohio was at the heart of it all. During a dark time in United States history, thousands of freedom seekers traveled the Underground Railroad through Ohio. The Buckeye State hosted about half of all fugitive slave traffic of the antebellum era. A mix of Northern and Southern settlers in the state added drama to a struggle that led to major benefits for the state and the country. Unfortunately, this epic past was obscured by silence and secrecy and then distorted with misinformation and folklore--until now. Author and native Ohioan Kathy Schulz accurately details the development and workings of Ohio's Underground Railroad with true stories of Addison White, John Parker and others.
