290 THE NATIONAL GEOGRAPHIC MAGAZINE Photograph by Dr. J . H. Gore THE SEA-FACE OF ONE OF THE DIKES OF HOLLAND (SEE TEXT, PAGE 286) According to the act of Parliament signed by Queen Wilhelmina on June 14, 1918, more than 523,440 acres of land will be reclaimed from the Zuider Zee by the building of an enormous dike measuring 230 feet in width. TIIE RESULT OF A BROKEN DIKE Holland's hourly peril is a "sword of Damocles" which frequently falls. In a single day the revengeful waters have carried away as many as 40,000 lives (see text, page 319), but the ingenuity of Dutch engineers and the patient industry of the Dutch people have gradually thwarted the sea.
