In the early twentieth century, many Americans were troubled by the way agriculture was becoming increasingly industrial and corporate. Mainline Protestant churches and cooperative organizations began to come together to promote agrarianism: the belief that the health of the nation depended on small rural communities and family farms. In Baptized with the Soil, Kevin M. Lowe offers for the first time a comprehensive history of the Protestant commitment to rural America. Christian agrarians believed that farming was the most moral way of life and a means for people to serve God by taking care of the earth that God created. When the Great Depression hit, Christian agrarians worked harder to keep small farmers on the land. They formed alliances with state universities, cooperative extension services, and each other's denominations. They experimented with ways of revitalizing rural church life--including new worship services like Rural Life Sunday, and new strategies for raising financial support like the Lord's Acre. Because they believed that the earth was holy, Christian agrarians also became leaders in promoting soil conservation. Decades before the environmental movement, they inspired an ethic of environmental stewardship in their congregations. They may not have been able to prevent the spread of industrial agribusiness, but their ideas have helped define significant and long-lasting currents in American culture.

Sixty percent of infectious human diseases are shared with other vertebrates. Alan Olmstead and Paul Rhode tell how innovations to combat livestock infections—border control, food inspection, drug regulation, federal research labs—turned the U.S. into a world leader in combatting communicable diseases, and remain central to public health policy.

Caenorhabditis Elegans has been a popular model organism for biological research for over thirty years and has been used to investigate many aspects of animal development, for example apoptosis, the Hox genes, signal transduction pathways, and the development of the nervous system. It has recently taken on new importance with the publication of the entire genome sequence in 1998. The first chapter gives all the basic information on C. elegans required to use it: it's natural history, anatomy, life cycle, development, and evolution. Information on how to obtain, grow, and maintain C. elegans for use as a model system is given in Chapter 4. Chapters 2 and 3 describe the genome project and show how to use genome sequence information by searching the database for homologues using different search methods and then how to analyse the search data. The next chapter gives the essential practical details of transformation and common uses for the technique. Chapter 6 covers reverse genetics and describes strategies for gene inactivation that are known to work in C elegans: epigenetic inactivation and mutational germ line inactivation. Chapter 7 is designed to help the user analyse phenotype by microscopy and includes Normaski, fluorescence, 4-dimensional, and electron microscopy. Techniques for studying the neurobiology of C. elegans are given in chapter 8. Chapter 9 describes the three commonly used approaches for studying gene expression and Chapter 10 deals with the common methods of molecular biology essential for gene characterization. C. elegans is not the ideal organism for biochemical studies, but chapter 11 describes several procedures for producing biochemically useful quantities of pure tissues. The final chapter is about conventional genetics and details the standard procedures for selfing and crossing; mutagenesis and mutant screening; characterization of mutants; gene mapping; temperature-shift experiments and mosaic analysis. Caenorhabditis Elegans: A Practical Approach will therefore provide all the background information necessary for use of C. elegans as a model system.

Before crude oil and the combustion engine, the industrialized world relied on a different kind of power - the power of the horse. Horses in Society is the story of horse production in the United States, Britain, and Canada at the height of the species' usefulness, the late nineteenth and early twentieth-century. Margaret E. Derry shows how horse breeding practices used during this period to heighten the value of the animals in the marketplace incorporated a intriguing cross section of influences, including Mendelism, eugenics, and Darwinism. Derry elucidates the increasingly complex horse world by looking at the international trade in army horses, the regulations put in place by different countries to enforce better horse breeding, and general aspects of the dynamics of the horse market. Because it is a story of how certain groups attempted to control the market for horses, by protecting their breeding activities or 'patenting' their work, Horses in Society provides valuable background information to the rapidly developing present-day problem of biological ownership. Derry's fascinating study is also a story of the evolution of animal medicine and humanitarian movements, and of international relations, particularly between Canada and the United States.
