A second edition, in two parts, of Volume 1 of this well-known reference series. This volume deals mainly with the olivine and garnet groups and also the humite group, zircon, sphene, vesuvianite, the Al2SiO5 (including mullite), topaz, staurolite and chloritoid. The disilicates and ring-silicates are covered in Volume 1B. In the years since the first edition was published, the quantity and scope of research on the olivines, garnets and the aluminosilicates has grown enormously and has given rise to a wide variety of literature. This book, which has been completely rewritten and considerably expanded, summarizes the important research results and presents them in an organized fashion. Each mineral chapter is divided into sections on structure, chemistry, optical and physical properties, distinguishing features and paragenesis. Each chapter is headed by a tabulation of mineral data and a sketch showing optical orientation, and concludes with full references to the literature. Diagrams of the crystal structures are presented and are followed by a discussion of the structural features. The chemical sections include a large number of analyses from which structural formulae have been calculated, illustrating the chemical and paragenetical variation exhibited by each mineral; phase equilibria in relevant systems are fully considered. In the sections on optical and physical properties, particular attention is paid to the correlation of these properties with chemical composition. The principal modes of occurrence are described and discussed in the paragenesis sections; here again correlation with chemistry is emphasized. 11 volumes are available in this series.
This volume deals with sulphates, carbonates, phosphates and halides, incorporating recent advances in investigative techniques. Each mineral chapter has sections on structure, chemistry, optical and physical properties, distinguishing features and paragenesis. Chapters are headed with brief tabulations of mineral data and a sketch of optical orientation. Results are included from ocean floor experimentation and deep sea drilling.
Hampshire County was formed from the Virginia counties of Augusta and Frederick in 1754. Later, during the American Civil War, it became the first Virginia county wholly in the territory that is now West Virginia. Mrs. Vicki Horton is the compiler of a number of Hampshire County genealogical source record collections, six of which are now available from Clearfield Company (see also items 9734, 9339, 9147, 9336, and 9335). Hampshire County Virginia Personal Property Tax Lists consists of alphabetically arranged lists of all persons who paid a property tax for every year between 1800 and 1814, except for 1808, when no tax was collected. For each taxpayer Mrs. Horton has coded the number of white tithables in the household, the number of horses owned, and the number of slaves, if any. On occasion, persons are identified with supporting information, such as occupation. All the taxpayers are readily identified in the comprehensive index at the back of the volume. Since this volume contains more than 20,000 entries, it is hard to imagine a better census approximation of Hampshire County residents for this time period.
Thomas OReiley, a wealthy and highly successful San Francisco businessman had spent five desperate, daunting years as a young man isolated on a South Pacific island. After his audacious return to San Francisco in 1896, OReiley married the only girl he had ever cherished, the beautiful Amanda McPherson. During these early years of the twentieth century, the United States is busy flexing its newly-found muscles, from the far-Western Pacific through Central America to the Caribbean. Meanwhile, prominent politicians and scandalous entrepreneurs were determined to sabotage one of the United States greatest engineering feats, the construction of the inter-ocean canal through the Isthmus of Panama. This loose alliance of vicious men and formidable politicians employ inside sources, corruption and murder in a daring conspiracy to satisfy their greed. OReiley is gradually drawn into a covert effort to prevent the assassination of President Theodore Roosevelt. But OReiley is troubled by his life and the trappings of success that camouflage his own uncertainties, longings and suppressed yearnings. His efforts to acknowledge and confront his passions and wanderlust lead to near-tragedy in the high Sierras. They are avoided only through his rediscovery of peace and solitude, his total acceptance by a ranching family and the mysterious encounter with a fugitive Indian shaman in the California Sierras that thrusts his life in a new direction.
