"Yes. What do those swans mean? Anything?" asked Ben, looking up at the stone gate towers.

"The swan is held almost in reverence by us Hollanders. These give the building its name--Zwanenburg, swan castle. That is all I know. This is a very important spot; for it is here that the wise ones hold council with regard to dike matters. The castle was once the residence of the celebrated Christian Brunings."

"What about HIM?" asked Ben.

"Peter could answer you better than I," said Lambert, "if you could only understand each other, or were not such cowards about leaving your mother tongues. But I have often heard my grandfather speak of Brunings. He is never tired of telling us of the great engineer--how good he was and how learned and how, when he died, the whole country seemed to mourn as for a friend. He belonged to a great many learned societies and was at the head of the State Department intrusted with the care of the dikes and other defences against the sea. There's no counting the improvements he made in dikes and sluices and water mills and all that kind of thing. We Hollanders, you know, consider our great engineers as the highest of public benefactors. Brunings died years ago; they've a monument to his memory in the cathedral of Haarlem. I have seen his portrait, and I tell you, Ben, he was right noble-looking. No wonder the castle looks so stiff and proud. It is something to have given shelter to such a man!"
