This is a detailed study of how the Somerset Levels, originally a large tract of marsh, were drained and reclaimed to becomes one of the most agriculturally productive areas of south-west England. The story of the draining of this region brings to light significant comparisons and contrasts with other reclaimed lowlands and extends our knowledge of one of the processes by which the British landscape has changed. This is an important book, which brings together information on an area that has until now received very little attention; it also shows just how early massive reclamation began. It will be of interest to both geographers and historians.
