A light yacht, chaste and elegant in its form, was gliding amidst the first dews of night over the immense lake, extending from Gibraltar to the Dardanelles, and from Tunis to Venice. The vessel resembled a swan with its wings opened towards the wind, gliding on the water. It advanced swiftly and gracefully, leaving behind it a glittering stretch of foam. By degrees the sun disappeared behind the western horizon; but as though to prove the truth of the fanciful ideas in heathen mythology, its indiscreet rays reappeared on the summit of every wave, as if the god of fire had just sunk upon the bosom of Amphitrite, who in vain endeavored to hide her lover beneath her azure mantle.

The yacht moved rapidly on, though there did not appear to be sufficient wind to ruffle the curls on the head of a young girl. Standing on the prow was a tall man, of a dark complexion, who saw with dilating eyes that they were approaching a dark mass of land in the shape of a cone, which rose from the midst of the waves like the hat of a Catalan.
