Polly Pullar has had a passion for red squirrels since childhood. As a wildlife rehabilitator, she knows the squirrel on a profoundly personal level and has hand-reared numerous litters of orphan kits, eventually returning them to the wild. In this book she shares her experiences and love for the squirrel and explores how our perceptions have changed. Heavily persecuted until the 1960s, it has since become one of the nations most adored mammals. But we are now racing against time to ensure its long-term survival in an ever-changing world. Set against the beautiful backdrop of Pollys Perthshire farm, where she works continuously to encourage wildlife great and small, she highlights how nature can, and indeed will, recover if only we give it a chance. In just two decades, her efforts have brought spectacular results, and numerous squirrels and other animals visit her wild farm every day.

A Shepherds Life: Impressions of the South Wiltshire Downs is Hudsons deeply textured portrait of a shepherding community centered on the figure of Caleb Bawcombe, rendered through episodic scenes of work, festivity, and hardship across the seasons. Combining oral biography with natural history, Hudsons prose is limpid yet exact, attentive to chalkland light, birdsong, and the craft of dogs and men. Set on the Salisbury Plain at the edge of Edwardian change, the book extends the English pastoral from Jefferies and Hardy into an ethnography of a vanishing economy. Born on the Argentine pampas, Hudson brought to England a lifelong habit of watchful wandering and an outsiders sympathy for open country. A self-taught ornithologist and celebrated nature writer, he tramped the Wiltshire downs gathering life histories from shepherds, sedimenting memory with field observation. Alarmed by enclosure, militarization, and mechanization, he shaped these interviews into a conserving art, preserving dialect, custom, and ecological knowledge before modernization effaced them. This book rewards readers of nature writing, social historians, and ecocritical scholars alike. Read it for its patient craft and humane intelligence: a luminous record of pre-mechanized husbandry and a masterclass in listening to place as carefully as to people.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

On the 22nd March 1878, complaint was made by Mr. Octavius Deacon, of Goldings Hill, Loughton, to Mr. Secretary Cross, that a serious attack by skin disease of his own infant had resulted from the use for nursery purposes of violet powder, which on analysis by Mr. G. Jones, F.C.S., had been found to contain in large proportion white arsenic; and further, Mr. Deacon stated his belief that a large and fatal prevalence of skin disease among infants in Loughton had been due to the use in a similar way of violet powder of a like sort. This representation was referred by Mr. Cross to the Local Government Board. On 25th March the Board received a communication from the clerk to the Epping Rural Sanitary Authority enclosing a statement by the Medical Officer of Health to the effect that a special mortality among infants in his district, already reported by him, had, he has now reason to believe, resulted from the use of violet powder impregnated with arsenic.
