He was to stay at court, and have his own cage. He had permission to go for a walk twice a day, and once a night. Twelve footmen attended him, each one holding tight to a ribbon tied to the bird's leg. There wasn't much fun in such outings.
The whole town talked about the marvelous bird, and if two people met, one could scarcely say "night" before the other said "gale," and then they would sigh in unison, with no need for words. Eleven pork-butchers' children were named "nightingale," but not one could sing.
One day the Emperor received a large package labeled "The Nightingale."
"This must be another book about my celebrated bird," he said. But it was not a book. In the box was a work of art, an artificial nightingale most like the real one except that it was encrusted with diamonds, rubies and sapphires. When it was wound, the artificial bird could sing one of the nightingale's songs while it wagged its glittering gold and silver tail. Round its neck hung a ribbon inscribed: "The Emperor of Japan's nightingale is a poor thing compared with that of the Emperor of China."
"Isn't that nice?" everyone said, and the man who had brought the contraption was immediately promoted to be "Imperial-Nightingale-Fetcher-in-Chief."
"Now let's have them sing together. What a duet that will be," said the courtiers.
So they had to sing together, but it didn't turn out so well, for the real nightingale sang whatever came into his head while the imitation bird sang by rote.
"That's not the newcomer's fault," said the music master. "He keeps perfect time, just as I have taught him."
Then they had the imitation bird sing by itself. It met with the same success as the real nightingale, and besides it was much prettier to see, all sparkling like bracelets and breastpins. Three and thirty times it sang the selfsame song without tiring. The courtiers would gladly have heard it again, but the Emperor said the real nightingale should now have his turn. Where was he? No one had noticed him flying out the open window, back to his home in the green forest.
