after rock, steered his way from tree to tree, till at length he arrived at the edge of the sea, at the foot of a mountain that he remembered to have seen in the cabinet of the present, where Rosalie was held captive.
Filled with joy, he made his way to the top of the mountain which pierced the clouds, and there he found a palace. He entered, and in the middle of a long gallery he discovered a crystal room, in the midst of which sat Rosalie, guarded night and day by genii. There was no door anywhere, nor any window.
