Robles, the Spanish governor, was foremost in noble efforts to save life and lessen the horrors of the catastrophe. He had previously been hated by the Dutch because of his Spanish or Portuguese blood, but by his goodness and activity in their hour of disaster, he won all hearts to gratitude. He soon introduced an improved method of constructing the dikes and passed a law that they should in future be kept up by the owners of the soil. There were fewer heavy floods from this time, though within less than three hundred years, six fearful inundations swept over the land. In the spring there is always great danger of inland freshets, especially in times of thaw, because the rivers, choked with blocks of ice, overflow before they can discharge their rapidly rising waters into the ocean. Adding to this that the sea chafes and presses against the dikes, it is no wonder that Holland is often in a state of alarm. The greatest care is taken to prevent accidents. Engineers and workmen are stationed all along in threatened places, and a close watch is kept up night and day. When a general signal of danger is given, the inhabitants all rush to the rescue, eager to combine against their common foe. As, everywhere else, straw is supposed to be of all things the most helpless in the water, of course, in Holland, it must be rendered the mainstay against a rushing tide. Huge straw mats are pressed against the embankments, fortified with clay and heavy stone, and once adjusted, the ocean dashes against them in vain. Raff Brinker, the father of Gretel and Hans, had for years been employed upon the dikes. It was at the time of a threatened inundation, when in the midst of a terrible storm, in darkness and sleet, the men were laboring at a weak spot near the Veermyk sluice, that he fell from the scaffolding and became insensible. From that hour he never worked again; though he lived on, mind and memory were gone. Gretel could not remember him otherwise than as the strange, silent man whose eyes followed her vacantly whichever way she turned, but Hans had recollections of a hearty, cheerful-voiced father who was never tired of bearing him upon his shoulder and whose careless song still seemed echoing near when he lay awake at night and listened. The Silver Skates Dame Brinker earned a scant support for her family by raising vegetables, spinning, and knitting. Once she had worked on board the barges plying up and down the canal and had occasionally been harnessed with other women to the towing rope of a pakschuyt plying between Broek and Amsterdam. But when Hans had grown strong and large, he had insisted on doing all such drudgery in her place. Besides, her husband had become so very helpless of late that he required her constant care. Although not having as much intelligence as a little child, he was yet strong of arm and very hearty, and Dame Brinker had sometimes great trouble in controlling him.
