Some few marvels of reclamation are to be seen in

various parts of Britain, though the sum ought to be at least trebled. It is not sufficiently realized how much science has contributed of late to such work. Thanks to chemical knowledge the Prince of Wales is reclaiming much heath-land in the Duchy ; thanks to botanical knowledge, chiefly to the appreciation of spartina grass, once barren marshes on the Essex seaboard have become useful pastures ; thanks to engineering science, we could, if we would, easily and cheaply reclaim areas both richer and wider than those now being recovered from the Zuyder Zee by the Dutch Government.
