"Yes, I see a great water," his mother admitted at last.

"That's it! It rises in the Côte d'Or, flows N.N.W. then W., and N.W. into the English Channel. It is more than twice as long as the Thames. Perhaps you'll see the tributaries flowing into it—the little rivers, the Oise, the Marne, the Yonne."

"No wonder the angels envy me him!" thought Zillah proudly.

They halted at Paris, putting up for the night, by the advice of a friendly fellow-traveller, at a hotel by the Gare de Lyon, where, to Zillah's joy and amazement, everybody spoke English to her and accepted her English gold—a pleasant experience which was destined to be renewed at each stage, and which increased her hope of a happy issue.

"How loud Paris sounds!" said Brum, as they drove across it. He had to construct it from its noises, for in answer to his feverish interrogations his mother could only explain that some streets were lined with trees and some foolish unrespectable people sat out in the cold air, drinking at little tables.

"Oh, how jolly!" said Brum. "But can't you see Notre Dame?"

"What's that?"

"A splendid cathedral, mother—very old. Do look for two towers. We must go there the first thing to-morrow."

"The first thing to-morrow we take the train. The quicker we get to the doctor, the better."

"Oh, but we can't leave Paris without seeing Notre Dame, and the gargoyles, and perhaps Quasimodo, and all that Victor Hugo describes. I wonder if we shall see a devil-fish in Italy," he added irrelevantly.
