"Is this the treasure you found in Italy?" he asked somewhat hoarsely.

"Yes; do you like it?"

"I think it beautiful! I am learning to know beauty when I see it, you know."

"Learning to know beauty when you see it, Captain Brooke! Didn't know gentlemen had to be taught that, as a rule!" cried Theo, laughing affectedly.

"Oh, aren't you confusing beauty and art?" said Melicent, finding her voice again.
