'Darwin cleared: official' This 1982 Times (7 January) head line of a first leader, reporting the astonishing case brought in Arkansas against compulsory teaching of a biblical account of creation, hopefully set at rest doubts about Darwin in the minds of a public confused by media presentations of such unfamiliar concepts as punctuated equilibria, cladism and phenetics. Mud sticks, but Darwin's perturbed ghost may have found some consolation in the concurrent celebrations at Grange-over-Sands, a modest township in Cumbria, UK, of the centenary of the publication of his less controversial book The Formation of Vegetable Mould through the Action of Worms. In the form of a symposium on earthworm ecology, this attracted some 150 participants, predominantly adrenalin-charged research workers in the full heat of peer-group interaction. This book comprises a selection of the more ecologically oriented papers contributed to the symposium, brutally edited in the interests of brevity and thematic continuity. The book opens with an appraisal of Darwin's earthworm work in its historical and philosophical context and relates his views on 'vegetable mould' to current concepts of humus formation. Thereafter, quotations from Darwin made out of piety have been rigorously excluded. Subsequent sections each comprise a review chapter and two or three 'case studies' presenting new data on a related topic.
This book is a concise and well-illustrated treatment of the conventional knowledge and modern utilities of earthworms. The first two chapters deal with earthworm morphology, food relationship, behavior, functional role, interaction with soil biota, and the influence of environmental factors. Earthworms found in the tropics and sub-tropics are also discussed in this section. The third chapter provides a good account of utilizing species of worms to produce high value manure through vermitechnology and its application in agriculture. The nutritional and medicinal values of earthworms are illustrated in the fourth chapter, while the fifth c provides information on how earthworms are used successfully as indicators of ecological perturbations, soil quality and for remediation of contaminated soils. The book will immensely benefit students, faculty and researchers in biological, agricultural and environmental sciences. It is also a source of information for anyone interested in knowing more about earthworms.

Five years after returning from his trip around the world, young Charles Darwin became the owner of Down House in Kent, England, where he moved his growing family, far away from the turmoil and distractions of London. He would live there for the rest of his life, and it would become the place where he began work on his masterpiece, On the Origin of Species. For almost twenty years, he used the garden around him as a laboratory. In the orchard, he conducted experiments on pollination. He built a dovecote where breeding new strains of pigeons helped him understand the intricacies of generation. On his daily walk along the sandbank, he observed how plants competed for survival. In solitude he struggled with the ideas of evolution that had haunted him since his voyage, which, in turn, gave him the courage to publish his revolutionary ideas. Bringing Darwin's garden to the present day, Boulter unfolds a shining portrait of the formation of one of England's greatest thinkers and his relationship with the place he loved, and shows how his experiments—conducted more than 150 years ago—are still revealing new proofs as we continue to search for the origins of life.
