This comprehensive study, with a foreword by Lord Killanin, looks at Irish forestry from the migration of the first wood species some 10,000 years ago to the present day. Part One, The Historical Background, examines the primeval forest and early settlers, woodlands, land title and tenure under the Celts, codified with Brehon law; Norman forest law imposed in the early medieval period; the Tudor conquest and plantations; and the development of estate and scientific forestry during the eighteenth and nineteenth centuries. It also considers the political dimension of Irish forestry, and socio-economic factors such as land hunger and agrarian reform. Part Two, Forestry in Modern Ireland, chronicles the twentieth century, beginning with the Irish Forestry Committee of 1907. In the struggle for independence, replenishing the countrys forestry stock was placed high on the list of national objectives. State afforestation schemes laid foundations gradually built upon during the mid-century as the techniques and role of forestry were debated, policies defined and planting programmes instituted. With Coillte established in 1989 and EC-aided expansion plans for the 1990s, private and state interests converge in a major national enterprise. The husbanding of Irelands natural resources and its documentation are now part of a broader environmental awareness. Forests are of inestimable importance. They provide and protect. They sustain the biosphere, regulate climate, nurture diversity, serve recreation, and yield wood: a commodity which contributes more than any other to society, as fuel, as industrial timber and in the form of paper the key medium of civilization. A History of Irish Forestry will be of interest to all concerned with Irelands past, and future.

In A History of Land Mammals in the Western Hemisphere, William Berryman Scott meticulously chronicles the evolution and diversity of terrestrial mammals that have inhabited North America and South America. The books analytical framework is deeply rooted in paleontological evidence, augmented by a thorough review of existing literature, which allows Scott to present a comprehensive narrative that interweaves geological contexts with biological evolution. His prose is both accessible and informative, striking a balance between scientific rigor and engaging storytelling. This work is an important contribution to the field of vertebrate paleontology and exemplifies the early 20th-century scholarly pursuit of integrating fossil records with contemporary ecological understanding. William Berryman Scott, a distinguished American paleontologist, dedicated his life to the study of mammals, significantly influencing the field through his research and advocacy for science in education. His academic lineage, rooted in the Princeton University and the American Museum of Natural History, provided him with rich access to fossil collections and data that informed his comprehensive survey on mammals. In this book, Scott eloquently expresses his passion for understanding the past and its implications for contemporary biodiversity. Readers with an interest in natural history, paleontology, and evolutionary biology will find Scotts work both enlightening and influential. Ideal for scholars and enthusiasts alike, A History of Land Mammals in the Western Hemisphere not only serves as an essential academic reference but also instills a sense of wonder about the rich tapestry of life that has flourished across these lands.

A History of Science is a five volume work written by two brothers dr. Henry Smith Williams and dr. Edward Huntington Williams with a goal to present fundamental principles of science, to point out how they have been discovered by our predecessors, and to trace the growth of these ideas from their first vague beginnings. The work is chronologically divided in five parts, each of them covering the epoch in which different branches of science have been lifted to the next level.Table of Contents:Volume I: Idea of the Science in Ancient History and Prehistoric Times (Egypt, Babylonia, Assyria, Ancient Greece and Rome);Volume II: The Beginnings of Modern Science (Science in Middle Ages, Eastern, Western, Galileo, Newton);Volume III: Modern Development of the Physical Sciences;Volume IV: Modern Development of the Chemical and Biological Sciences;Volume V: Aspects of Recent Science.

From the early misfortunes of Eve, condemning her descendants to a dubious reputation for fruit management, to the acclaimed successes of plant breeders such as the eccentric Ellen Willmott who combined bankruptcy with iris breeding, the fortunes of the female gardener have been as varied as their roles.Telling the tales of the sixteenth-century housewife, who neatly sidestepped accusations of herbal witchcraft while working her plot, and the unconventional Ladies of Llangollen, who eloped together and created their gothic garden and many other women besides, A History of Women in the Garden showcases female horticulturists through the centuries. An enlightening and entertaining read that will allow the reader to gain fresh enthusiasm for even the most menial of garden tasks, and realise that hundreds of women have trod the garden path before.

In "A Hundred Anecdotes of Animals," Percy J. Billinghurst compiles a rich tapestry of delightful and thought-provoking tales that illuminate the intricate relationships between humans and the animal kingdom. Through a blend of humor and empathy, Billinghurst employs a narrative style that is both engaging and reflective, weaving anecdotes that span not only personal experiences but also folklore and historical observations. This book stands as a testament to the literary tradition of animal literature, situating itself among the greats while exploring themes of companionship, loyalty, and the profound emotional lives of animals. Billinghurst, a naturalist and passionate advocate for animal rights, draws upon his extensive experiences in zoos, wildlife sanctuaries, and domestic settings to create a personal yet universal narrative. His profound respect for animals and keen observation skills are evident throughout the text, revealing a mind attuned to the subtleties of their behaviors and the significance of their interactions with humans. This background undoubtedly inspired him to bring these stories to a broader audience, encouraging readers to reflect on their own relationships with animals. I highly recommend "A Hundred Anecdotes of Animals" to anyone interested in the beauty and complexity of the animal world. Whether you are a lover of literature, a veterinarian, or simply an animal enthusiast, BillinghurstAos compassionate narratives will captivate and inspire you to consider the myriad ways animals enrich our lives.

The Poet of Omaezaki In the winter of 2005 on Omaezaki Beach a seagull flew low and a feather fell from it. The feather floated to my feet. It was winter and I was in winter clothes. Overcoat, shirt, pants and shoes. All black, my artist s uniform. I am inspired by the photo of Albert Einstein on the beach in Santa Barbara California USA in winter. Einstein liked to say that the universe is a sea of waves. Of course electromagnetic and gravitational. I was only wetting the soles of my shoes. Discharging bad energies. After more than 15 years of trying to write a booklet of poetry; I thought the feather is a gift from God... The symbol of The Writers!!!

A bold, provocative exploration of the tension between our evolutionary history and our modern woes and what we can do about itWe are living through the most prosperous age in all of human history, yet we are listless, divided and miserable. Wealth and comfort are unparalleled, but our political landscape is unmoored, and rates of suicide, loneliness and chronic illness continue to skyrocket. How do we explain the gap between these truths? And how should we respond?For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our woes is clear: the modern world is out of sync with our ancient brains and bodies. We evolved to live in clans, but today many people dont even know their neighbours names. Survival in our earliest societies depended on living in harmony with nature, but today the food we eat, the work we do even the light we absorb is radically different from what our minds and bodies evolved to expect.In this book, Heying and Weinstein draw on decades of their work teaching in college classrooms and exploring earths most biodiverse ecosystems to confront todays pressing social ills from widespread sleep deprivation and dangerous diets to damaging parenting styles and backward education practices. A Hunter-Gatherers Guide to the 21st Century outlines a science-based worldview that will empower you to live a better, wiser life.
