Polder

Polder, the name given in Holland and Flanders to marsh land reclaimed from river or sea. The general method of reclaiming is to erect a dyke to keep out the lower tides and gradually raise and extend it as occasion offers. The lake of Haarlem, in Holland, has been converted into polder, and all along the lower Scheldt may be seen fertile polders covered with cattle and having far inland the Temains of ancient dykes, while nearer the river fresh polders are in course of formation. A scheme is afoot to add many thousands of acres to the cultivable land of Lincolnshire by the adoption of similar measures.
