The party took rooms at the Occidental Hotel and the very first evening Madam Urso was honored by a serenade, though no announcement of her arrival had been made. Certainly, the musical people of the Pacific Slope were eager to welcome her. It seemed so, for on announcing a concert at Platt Hall, there was a greater demand for tickets than had ever been known in that part of the country for any entertainment whatever its character. Three more concerts were given with every available seat and standing place occupied, and then three sacred concerts on successive Sunday evenings at the California Theatre, were announced. All of these concerts were of a classical character, the first of the kind ever given in the State and to bring them out properly the best talent to be found was engaged, including the Brignoli Opera Troupe then traveling in California. Never in her experience had concert giving been more successful and profitable than here. It seemed as if she had captured all their hearts and brought the golden State to her feet by one wave of her violin bow. Deeply sensible of the feelings of respect and admiration entertained for her by the people she resolved in some way to testify her appreciation and to give material expression of her thanks. She looked about for some worthy institution upon which she could bestow the benefit of a series of concerts, or musical festival. After some investigation and private correspondence Madam Urso wrote the following letter that was dated at the Occidental Hotel, San Francisco, December 1st 1869. _To the President and Board of Directors of the Mercantile Library Association of San Francisco_: GENTLEMEN: The present embarrassment of your Society having come to my knowledge, and wishing in some suitable manner to show my gratitude to the people of this city for the kindness and appreciation I have met with during my visit, I have thought of no better method to do so than in offering you the benefit of a grand musical entertainment such as I originally intended giving here, with the sincere hope that it may prove a help towards relieving the Mercantile Library of its present difficulties. Should my offer be accepted, I will, gentlemen, consecrate all my time during the two months necessary for its preparation, to make it a grand success. I am gentlemen, Yours obediently CAMILLA URSO.
