Date 1942-05 Abstract Where the top layer of clayey substance was thin and the underlying peat layer thick, the shrinkage of the latter had been such that the clay-filled gullies appeared as ridges of about ½ to 1 m high in the field. Farmers sometimes call these ridges ,,natural dykes". In some places they have dug up parts of these ancient depots of good clay and distributed the fertile substance on their fenlands. This was the case south of the Damsterdiep. In Walcheren practically all villages, main roads and farms have been built upon these ridges. In ~roningen north of the Damsterdiep, where the clay layer is thicker, the ridges are not so well developed, and the villages and farmsteads have little relation to the old peat-time gullies.
