William Marshall (1745–1818), from farming stock, became a farmer and then estate manager and land agent after several years spent conducting business in the West Indies. A pioneer of scientific methods of farming, he published widely on best practice, and was also known for his geographical surveys of agriculture. This two-volume 1789 work covers the county of Gloucestershire, but also includes dairy management in north Wiltshire and the orchards and fruit products of Herefordshire. A hands-on reporter, Marshall stayed in the vale of Gloucester to learn the art of cheese-making, and then spent a year in various locations studying local farming practice. Volume 2 covers the Cotswold Hills and the vale of Berkeley, with detailed descriptions of dairy farming in these areas. A section is devoted to Herefordshire, its orchards, and the manufacturing processes and marketing of its famous 'fruit liquors', cider and perry.
