First published in 1953, as the second edition of a 1942 original, this book provides an accessible account regarding field drainage, targeted at those involved in the organisation and supervision of the drainage process. The text was written to draw attention 'to the fundamentals of the subject, to portray a philosophy of draining, and to deal with the factors involved and the way in which they influence events in the soil'. Numerous illustrative figures and a bibliography are included. This book will be of value to anyone with an interest in field drainage and the history of agriculture.
