This report deals with biological evidence from two sites within the area of the Roman civil town or colonia close to the River Ouse and the probable Roman river crossing. Both sites were extensively sampled and the material has provided the first opportunity in York to examine richly organic waterlogged Roman deposits formed on surfaces rather than as the fills of wells or other subsurface features.

From the tiny shrew to the black bear, Pennsylvania's hills and valleys are teeming with sixty-three species of wild mammals. Many of these animals are rarely seen except when pursued by an interested biologist, mammologist, or nature photographer. Now, with the publication of this book, student, scholar, and nature lover alike will have a ready reference to distinguish between a deer mouse and a white-footed mouse, to identify raccoon tracks, and to learn about Pennsylvania's other inhabitants.An attractive backpack-size volume, written in lively prose, the Guide to the Mammals of Pennsylvania opens with a short introduction to Pennsylvania's environment and the characteristics defining a mammal. The bulk of the book consists of species accounts of the mammals grouped into families and orders. Each account includes a short list of data, a Pennsylvania range map, a North American range map, and a narrative of the physical, ecological, and behavioral characteristics of the species.Exciting photographs of each of the species in its natural habitat, 17 in color, and drawings of animal tracks are especially useful for identification, and a glossary and a bibliography provide definitions and references for the serious reader. Naturalists, whether amateur or professional, will find the book useful in the field; it will be an indispensable tool in the classroom.
Coal In Appalachia Cover

Coal, the nation's most abundant fossil fuel and the only one that is exported, represents one of our most valuable natural resources. This study undertakes a thorough review of the economics of the Appalachian coal industry. It establishes, first of all, the international framework within which the American and the Appalachian coal industry function. It next examines the underlying principles that govern the production of and the demand for coal. This demand is influenced not only by price but also by world politics, the economic well-being of dozens of countries, government regulation, and the availability of fuel substitutes. Included are a comprehensive treatment of the regulation of the industry, the effects of coal utilization on air quality, land reclamation, safety, transport, and legislation pertaining to port use. In conclusion, Harvey looks at the prospects for Appalachian coal, considering the impact of technologies such as fluidized bed combustion and coal-water slurry and the issue of energy policy and fuel alternatives. The picture that emerges is not unexpected -- an industry whose recovery and enduring health depend on resurgence of world and domestic economic activity, social and political stability, and government regulation.

Both strategic and economic considerations make desirable the development of alternatives to petroleum as a source of energy and chemicals. Alcohol is one such alternative, and the experience of Brazil, a world leader in its production, provides a unique contribution to industrial policy for other nations. This book will be a valuable reference for all those concerned with energy sources for the future.
American Ideology of National Science, 1919-1930, The Cover

Ronald C. Tobey provides a provocative analysis of the movement to establish a national science program in the early twentieth century. Led by several influential scientists, who had participated in centralized scientific enterprises during World War I, the new effort to conjoin science and society was an attempt to return to earlier progressive values with the hope of producing science for society's benefit. The movement was initially undermined by the new physics, and Einstein's theories of relativity, which shattered traditional views and alienated the American public. Nationalized research programs were tempered by the conservatism of corporate donors. Later, with the disintegration of progressivism, the gap between science and society made it impossible for the two cultures to unite.
