Viva Garibaldi! sang a young Italian boy in an uptown street, accompanying himself on a violin which, from its battered appearance, seemed to have met with hard usage. As the young singer is to be the hero of my story, I will pause to describe him. He was twelve years old, but small of his age. His complexion was a brilliant olive, with the dark eyes peculiar to his race, and his hair black. In spite of the dirt, his face was strikingly handsome, especially when lighted up by a smile, as was often the case, for in spite of the hardships of his lot, and these were neither few nor light, Filippo was naturally merry and light-hearted.
