_Le petit lundi_ of the Empress was not so _petit_ as I expected; there were at least four or five hundred people present. I was presented to the Princess Mathilde (the cousin of the Emperor), a very handsome and distinguished-looking lady, who is married to and separated from Prince Demidoff. Her palace is directly opposite our hotel. I was also presented to the Princess Clothilde, and many others. I was very nervous before singing, but after my first song I did very well. There was dancing, and everything was very unceremonious and easy. I think (I will just say it to you, dear mama) that I had a success. Their Majesties were very kind, and thanked me many times, and the Duke de Morny said that he was very proud of his protégée, for it was he who had suggested to the Empress that I should sing for them. It was a delightful evening, and I enjoyed myself and my little triumph immensely. I made the acquaintance of the Austrian ambassador and the Princess Metternich. She seemed very pleasant, and put me directly at my ease. She is far from being handsome, but dresses better than any woman in Paris, and has more _chic_. In fact, she sets the fashion as much as the Empress does. The Emperor, at the instigation of the Duke de Morny, has given orders for the construction of a bridge over the Marne near Petit Val, a thing we needed greatly. When you were here, if you remember, one had to walk from the station to the river, about a little quarter of a mile. Once there you had to wave and shout for the ferryman, who, before allowing you to get on the boat, would attend to what cattle or merchandise were waiting there for transport. I do not think the bridge would have been built had not the Duke de Morny come out by train to Petit Val to avoid the long drive of twelve miles from Paris, and had been bored by this primitive means of transporting his august person. He said he was astonished and mortified that such a state of things should exist so near Paris. So was every one else. Otherwise the "bac" would have gone on forever. The Carnival has never been so whirlwindy as it has been this year; and I don't know how the purses of our lords and masters are going to hold out; and while the poor, "whom we have always with us," are getting rich, the rich, whom we don't always have, alas! are getting poor. For the private fancy-dress ball at the Tuileries last Monday, to which the guests were invited by the Empress, Worth alone made costumes to the tune of two hundred thousand dollars, and yet there were not four hundred ladies invited.
