“What is it?” said Sylvie anxiously.

“My old enemy!” groaned the Professor. “Lumbago—rheumatism—that sort of thing. I think I’ll go and lie down a bit.” And he hobbled out of the Saloon, watched by the pitying eyes of the two children.

“He’ll be better soon!” the Elfin-King said cheerily. “Brother!” turning to the Emperor, “I have some business to arrange with you to-night. The Empress will take care of the children.” And the two Brothers went away together, arm-in-arm.

The Empress found the children rather sad company. They could talk of nothing but “the dear Professor,” and “what a pity he’s so ill!”, till at last she made the welcome proposal “Let’s go and see him!”

The children eagerly grasped the hands she offered them: and we went off to the Professor’s study, and found him lying on the sofa, covered up with blankets, and reading a little manuscript-book. “Notes on Vol. Three!” he murmured, looking up at us. And there, on a table near him, lay the book he was seeking when first I saw him.

“And how are you now, Professor?” the Empress asked, bending over the invalid.

The Professor looked up, and smiled feebly. “As devoted to your Imperial Highness as ever!” he said in a weak voice. “All of me, that is not Lumbago, is Loyalty!”

“A sweet sentiment!” the Empress exclaimed with tears in her eyes. “You seldom hear anything so beautiful as that—even in a Valentine!”

“We must take you to stay at the seaside,” Sylvie said, tenderly. “It’ll do you ever so much good! And the Sea’s so grand!”

“But a Mountain’s grander!” said Bruno.
