"Oh," said Alex uncertainly. She was invaded by unreasoning disappointment. "But how could we do it?"

"Oh, well, notes, you know—just keep notes of anything that struck us particularly, and then put it in together later. We should have to do a good deal of it by correspondence, of course.... I say, are you a conventional person?"

"Not in the least," said Alex hastily.

"I'm glad of that. I'm afraid I'm rather desperately unconventional myself. Of course, in a way it might be rather unconventional, you and me corresponding—but would that matter?"

"Not to me," said Alex resolutely.

"That's splendid. We could do a lot that way, and then I hope, of course, that you'll let me come and see you in London."

"Of course," Alex cried eagerly. "I don't know the exact date when we shall be back, but I could let you know. Have you got the address?"

"Clevedon Square—"

She hastily supplied the number of the house.

"Oh, that's all right. I'm sure to forget it," said Noel easily; "but I shall find you in the books, I suppose."
