The Marquis d'Aoust happened to sit next to me at table (I say happened, but I believe he manoeuvered so as to do so), and, taking me unawares between two mouthfuls of _truites saumonées_, decoyed me into accepting a stupendous proposition of his, which was to help him to get up an operetta which he had had the courage to compose. He said the idea had just come into his head; but I thought, for an impromptu idea, it was rather a ripe one, as he had brought the music with him, and had already picked out those he thought could help, and checked them off on his lean fingers. He said the operetta had one act only, which I thought was fortunate, and that it needed only four actors, which I thought was still more fortunate. The next thing to be done, he said, was to get the singers' consent. I should have said it was the first thing to be done; but he was so bubbling over with enthusiasm that he was sure every one would jump at the chance of taking part. He seized the first moment after their Majesties had retired to pounce upon those he had selected, and having obtained their consent he proposed a walk in the long, so-called Treille or Berceau. Napoleon I. built this walk, which is one thousand meters in length and reaches to the edge of the forest, for the Queen Marie Louise. I must say I pitied her toes if she walked there often on as cold a day as to-day; I know mine ached as we paced to and fro while the Marquis explained the operetta. It was really too cold to stay out-of-doors, and we turned back to the little salon, called the _Salon Japonais_, to finish the séance there. "What part am I to take?" asked Prince Metternich. As he could not be anything else, he accepted the role of prompter, and promised all the help he could give. When I went to the Empress's tea this afternoon I took those questions Aunt M* sent me from America. You know them. You have to write what your favorite virtues are, and if you were not yourself, who you would like to be, and so forth. I was glad to have something new and original which might amuse people. The Empress, seeing the papers in my hand, asked me what they were. I told her that they were some questions: a new intellectual pastime just invented in America. "Do they invent intellectual pastimes in America?" she asked, looking at me with a smile. "I thought they only invented money-making." "They do that, too," I replied; "but they have also invented these questions, which probe the mind to the marrow and unveil the soul." She laughed and said, "Do you wish me to unveil my soul, _comme cela, à l'improviste_?" I answered, "Perhaps your Majesty will look at them at your leisure. I hardly dare to ask the Emperor; but if he would also look at them I should be so happy." "Leave them with me, and to-morrow we will see; in any case my soul is not prepared to-day." So I left the papers with her.
