Book Description
Winner of the International Lannan Literary Award for Nonfiction Animal tracks, word magic, the speech of stones, the power of letters, and the taste of the wind all figure prominently in this intellectual tour de force that returns us to our senses and to the sensuous terrain that sustains us. This major work of ecological philosophy startles the senses out of habitual ways of perception. For a thousand generations, human beings viewed themselves as part of the wider community of nature, and they carried on active relationships not only with other people with other animals, plants, and natural objects (including mountains, rivers, winds, and weather patters) that we have only lately come to think of as "inanimate." How, then, did humans come to sever their ancient reciprocity with the natural world? What will it take for us to recover a sustaining relation with the breathing earth? In The Spell of the Sensuous David Abram draws on sources as diverse as the philosophy of Merleau-Ponty, Balinese shamanism, Apache storytelling, and his own experience as an accomplished sleight-of-hand of magician to reveal the subtle dependence of human cognition on the natural environment. He explores the character of perception and excavates the sensual foundations of language, which--even at its most abstract--echoes the calls and cries of the earth. On every page of this lyrical work, Abram weaves his arguments with a passion, a precision, and an intellectual daring that recall such writers as Loren Eisleley, Annie Dillard, and Barry Lopez.

Book Description
A 75th anniversary e-book version of the most important and practical self-help book ever written, Alcoholics Anonymous. Here is a special deluxe edition of a book that has changed millions of lives and launched the modern recovery movement: Alcoholics Anonymous. This edition not only reproduces the original 1939 text of Alcoholics Anonymous, but as a special bonus features the complete 1941 Saturday Evening Post article “Alcoholics Anonymous” by journalist Jack Alexander, which, at the time, did as much as the book itself to introduce millions of seekers to AA’s program. Alcoholics Anonymous has touched and transformed myriad lives, and finally appears in a volume that honors its posterity and impact.

Book Description
The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.

Book Description
For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.

Book Description
NATIONAL BESTSELLER • A modern classic of true crime, set in a most beguiling Southern city—now in a 30th anniversary edition with a new afterword by the author “Elegant and wicked . . . might be the first true-crime book that makes the reader want to book a bed and breakfast for an extended weekend at the scene of the crime.”—The New York Times Book Review Shots rang out in Savannah’s grandest mansion in the misty, early morning hours of May 2, 1981. Was it murder or self-defense? For nearly a decade, the shooting and its aftermath reverberated throughout this hauntingly beautiful city of moss-hung oaks and shaded squares. In this sharply observed, suspenseful, and witty narrative, John Berendt skillfully interweaves a hugely entertaining first-person account of life in this isolated remnant of the Old South with the unpredictable twists and turns of a landmark murder case. It is a spellbinding story peopled by a gallery of remarkable characters: the well-bred society ladies of the Married Woman’s Card Club; the turbulent young gigolo; the hapless recluse who owns a bottle of poison so powerful it could kill every man, woman, and child in Savannah; the aging and profane Southern belle who is the “soul of pampered self-absorption”; the uproariously funny drag queen; the acerbic and arrogant antiques dealer; the sweet-talking, piano-playing con artist; young people dancing the minuet at the black debutante ball; and Minerva, the voodoo priestess who works her magic in the graveyard at midnight. These and other Savannahians act as a Greek chorus, with Berendt revealing the alliances, hostilities, and intrigues that thrive in a town where everyone knows everyone else. Brilliantly conceived and masterfully written, Midnight in the Garden of Good and Evil is a sublime and seductive reading experience.
