On passing Rundlestone, a hidden rock upwards of a mile from the southern shore of the Land's End peninsula, we came in sight of the Wolf Rock, about ten miles off the coast.  It was one of the greatest dangers in the English Channel, for the beacon placed on it was not visible at night or during thick weather.  Attempts were made to fix bells on the rock, which might be rung by the waves dashing against them; but the first gale quickly carried away the well-intentioned contrivance.
