In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.

An elegant new edition of a classic book from one of the twentieth century's greatest garden writers. This landmark work on creating a garden was first published in 1956 and has rarely been out of print since. We Made a Garden is the story of how Margery Fish, one of the leading British gardeners of the mid-20th century, and her husband Walter transformed an acre of wilderness into a stunning cottage garden, still open to the public at East Lambrook Manor, Somerset, England. Quirky and readable, this book details her creation of a world-renowned cottage garden, as well as her battles with Walter in the process, who preferred the standard suburban approach. In this beautiful and timeless work, she recounts the trials and tribulations, the successes and failures of her venture with ease and humour. Topics covered are colourful and diverse, ranging from the most suitable hyssop for the terraced garden through composting, hedges and making paths to the best time to lift and replant tulip bulbs. This book has been hailed as everything from a blueprint for the creation of a modern cottage garden to a feminist manifesto, and the author's practical knowledge, imaginative ideas and general good sense will encourage and inspire gardeners everywhere.
On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),[3] published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
