When he had gone, however, a considerable distance, he suddenly turned round, darted after the vessel, and before the Pilot-fish could overtake him and interpose, snapped at the bait and was taken. In hoisting him up, one of the Pilots was observed to cling to his side until he was half above water, when it fell off.
