Auber has given me all his operas, and I have gone through them all with him for his music. I sing the laughing song in "Manon Lescaut" and the bolero in "Diamants de la Couronne." These two are my favorite songs and are very difficult. In the laughing song I either laugh too much or too little. To start laughing in cold blood is as difficult as to stop laughing when once started. The bolero is only a continuous display of musical fireworks. NEW YORK, _May, 1864._ When we arrived in New York (we went to visit my sister and my mother) we were overwhelmed with invitations of all kinds. I made a most (to me) interesting acquaintance at this _soirée_, a Mrs. Henry Fields, who I found out was the famous and much-talked-about "Lucie," the governess in the trial of the Duc de Praslin. Every one was convinced of her innocence (she pleaded her own case, refusing the aid of a lawyer). Nevertheless, she was the cause of the death of the Duchess, as the Duke killed his wife because she refused to give "Lucie" a letter of recommendation, and he became so enraged at her refusal that he first tried to strangle her, and then shot her. I had heard so much about this murder (it was along ago), and knew all the details, and, what was more, I knew all the children of the unhappy woman whose only crime was to love her husband too much, and to resent "Lucie's" taking away the love of her children from her! Warning to young women: Don't love your husbands too much, or don't engage a too attractive governess. PHILADELPHIA, _July, 1864._ DEAR AUNTY,--We came from New York a few days ago, and are staying with mama's friend, Mrs. M----, who is a very (what shall I say?) fascinating but a very peculiar person. She is a curious mixture of a poetess and a society woman, very susceptible, and of such a sensitive nature that she seems always to be in the hottest of hot water, and at war with all her neighbors; but she routs all her enemies and manages everything with a high hand.
