For hitherto the Tower of D**o has been spared an appearance in our art galleries only by the circumstance that it cannot well be got before the painter's easel. It is built upon the outermost point of a rocky promontory of the great island of D**o. The projecting headland lies obliquely across the northern current, and the sea makes a ceaseless seething whirlpool round the obstruction. The sea-bottom all around is strewn with most perilous reefs. Among their intricate labyrinths even the skiffs of the most adroit boatmen are in danger of being dashed in pieces.
