SCENE: The terrace of the Hotel Regina Margherita, on the cliff at Sorrento, overlooking the Bay of Naples.There is a view of the bay and its semi-circular coast-line, dotted with villages; Vesuvius gray in the distance. Across the stage at the rear runs a marble balustrade about three feet high, guarding the edge of the cliff. Upon the left is seen part of one wing of the hotel, entrance to which is afforded by wide-open double doors approached by four or five marble steps with a railing and small stoop. The hotel is of pink and white stucco, and striped awnings shield the windows. Upon the right is a lemon grove and shrubberies. There are two or three small white wicker tea-tables and a number of wicker chairs upon the left, and a square table laid with white cloth on the right.As the curtain rises mandolins and guitars are heard, and the "Fisherman's Song," the time very rapid and gay, the musicians being unseen.
