Jibber the Kibber

To decoy a vessel ashore by exhibiting a ship's side light on the beach. The light is carried along the margin of the water, the man holding it giving a sinking and rising action to it as he walks along in imitation of a vessel's motion. A ship's captain seeing this light inshore considers that there is plenty of searoom, and in consequence his vessel may become stranded by entertaining a false idea as to his position.
