INTRODUCTION There is a very large class of persons alive to-day who believe that not only is communication with the dead possible, but that they themselves have had actual experience of it. Many of these are eminent in scientific research, and on any other subject the world in general would accept their evidence. There is possibly a larger class of persons who hold that all such communications, if genuine, come not from the dead but from the devil. This is the taught opinion of the Roman Catholic Church. A third class, far more numerous than both of these, is sure that any one who holds either of these beliefs is a dupe of conjurers, or the victim of his own disordered brain. This type of robust intellect has, during the last ten decades, affirmed that hypnotism, aviation in machines heavier than air, telepathy, wireless telegraphy, and other non-proved phenomena, are superstitious and unscientific balderdash. In an earlier century it was equally certain that the earth did not go round the sun. It is, happily, never disconcerted by the frequency with which the superstitions and impossibilities of one generation become the science of the next. The first part of this book may be accepted by the first of these three classes, the second by the second, and none of it by the third. Its aim is to state rather than solve the subject with which it deals, and to suggest that the dead and the devil alike may be able to communicate with the living.

"A powerful coming-of-age story of self-discovery and overcoming fear.”—Kirkus Reviews, starred review Ato hasn’t visited his grandmother’s house since he was seven. He’s heard the rumors that she’s a witch, and his mother has told him he must never sit on the old couch on her porch. Now here he is, on that exact couch, with a strange-looking drink his grandmother has given him, wondering if the rumors are true. What’s more, there’s a freshly dug hole in her yard that Ato suspects may be a grave meant for him. Meanwhile at school, Ato and his friends have entered a competition to win entry to Nnoma, the island bird sanctuary that Ato’s father helped created. But something is poisoning the community garden where their project is housed, and Ato sets out to track down the culprit. In doing so, he brings his estranged mother and grandmother back together, and begins healing the wounds left on the family by his father’s death years before. And that hole in the yard? It is a grave, but not for the purpose Ato feared, and its use brings a tender, celebratory ending to this deeply felt and universal story of healing and love from one of Ghana’s most admired children’s book authors.

Across the Stream By E.F. Benson There was something odd about females, and it was a mystery into which he did not at all want to enquire. They wore skirts, which perhaps concealed some abnormality, which would be fearful to contemplate...

Stream Ecosystems in a Changing Environment synthesizes the current understanding of stream ecosystem ecology, emphasizing nutrient cycling and carbon dynamics, and providing a forward-looking perspective regarding the response of stream ecosystems to environmental change. Each chapter includes a section focusing on anticipated and ongoing dynamics in stream ecosystems in a changing environment, along with hypotheses regarding controls on stream ecosystem functioning. The book, with its innovative sections, provides a bridge between papers published in peer-reviewed scientific journals and the findings of researchers in new areas of study. - Presents a forward-looking perspective regarding the response of stream ecosystems to environmental change - Provides a synthesis of the latest findings on stream ecosystems ecology in one concise volume - Includes thought exercises and discussion activities throughout, providing valuable tools for learning - Offers conceptual models and hypotheses to stimulate conversation and advance research

Island in the Stream introduces an original genre of ethnographic history as it follows a community on Mayotte, an East African island in the Mozambique Channel, through eleven periods of fieldwork between 1975 and 2015. Over this 40-year span Mayotte shifted from a declining and neglected colonial backwater to a full d?partement of the French state. In a highly unusual postcolonial trajectory, citizens of Mayotte demanded this incorporation within France rather than joining the independent republic of the Comoros. The Malagasy-speaking Muslim villagers Michael Lambek encountered in 1975 practiced subsistence cultivation and lived without roads, schools, electricity, or running water; today they are educated citizens of the EU who travel regularly to metropolitan France and beyond. Offering a series of ethnographic slices of life across time, Island in the Stream highlights community members' ethical engagement in their own history as they looked to the future, acknowledged the past, and engaged and transformed local forms of sociality, exchange, and ritual performance. This is a unique account of the changing horizons and historical consciousness of an African community and an intimate portrait of the inhabitants and their concerns, as well as a glimpse into the changing perspective of the ethnographer.

Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

Great blue herons, yellow birches, damselflies, and beavers are among the talismans by which Bill Roorbach uncovers a natural universe along the stream that runs by his house in Farmington, Maine. Populated by an oddball cast of characters to whom Roorbach ("The Professor") and his family might always be considered outsiders, this book chronicles one man's determined effort—occasionally with hilarious results—to follow his stream to its elusive source. Acclaimed essayist and award-winning fiction writer Bill Roorbach uses his singular literary gifts to inspire us to laugh, love, and experience the wonder of living side by side with the natural world.

Hydrology covers the fundamentals of hydrology and hydrogeology, taking an environmental slant dictated by the emphasis in recent times for the remediation of contaminated aquifers and surface-water bodies as well as a demand for new designs that impose the least negative impact on the natural environment. Major topics covered include hydrological principles, groundwater flow, groundwater contamination and clean-up, groundwater applications to civil engineering, well hydraulics, and surface water. Additional topics addressed include flood analysis, flood control, and both ground-water and surface-water applications to civil engineering design.
