"Oh, what is that?" asked little Elsie.

"A framework of timbers crossing each other, pointed on the lower edge with iron and hung by chains in grooves in the chief gateway of the castle, so that on the sudden appearance of an enemy it could be let down to keep him out more quickly than the drawbridge could be raised to prevent his crossing the moat, or the gates shut."

"And what is a moat?"

"A ditch or canal. But you shall see one presently, and a portcullis also."

"Oh, I'm so glad we came here to the White City!" cried Elsie, skipping along by her father's side; "it's so lovely and there are so many curious things to see."

"Yes, it is a pleasant way of gaining knowledge; pleasanter than learning lessons and reciting them to papa; is it not, daughter?" asked the captain, smiling down into the bright little face.

"Yes, sir; but that's not a hard way, either, 'cause my papa is so kind, and loves me and makes the lessons easy."

They soon reached the castle, crossed the moat by the drawbridge, passed through the arched gateway, under the portcullis, the young folks, and indeed the older ones also, gazing at it with much curiosity, and entered a spacious hall, the walls of which were hung with bows and ancient weapons, and armor such as was worn by warriors of feudal times.

From the hall was an entrance to a museum, where were shown many articles interesting as having belonged to those old times when the homes of knights and barons were such castles as this.

When they had looked their fill at all these they left the castle for the village surrounding it, which consisted of reproductions of very old German houses with small porticos and sharp gables.
