"Here is a marvellous thing, little brother," said Bee. "The castle is in the middle of the whole earth, and we, who are on the Keep, which is in the middle of the castle, are now in the middle of the whole world. Ha! ha! ha!"

And really the skyline was around the children like a circle of which the Keep was the centre.

"We are in the middle of the world. Ha! ha! ha!" George repeated.

Then both began to think.

"What a pity it is that the world is so big!" said Bee. "You can lose yourself in it and be separated from your friends."

George shrugged his shoulders.

"How nice it is that the world is so big! You can look for adventures in it. Bee, when I am grown up I mean to conquer those mountains which are right at the end of the earth. It is there that the moon rises. I will catch it as I go along and give it to you, my Bee."

"That's it," said Bee; "you will give it to me and I will set it in my hair."

Then they began to look for the places they knew as if on a map.

"I know perfectly where we are," said Bee (who knew nothing of the sort), "but I cannot guess what all those little square stones sown on the side of the hill are."
