It seems that some honest mariners of Dover, or Sandwich, or some one of the Cinque Ports, had after a hard chase succeeded in killing and beaching a fine whale which they had originally descried afar off from the shore. Now the Cinque Ports are partially or somehow under the jurisdiction of a sort of policeman or beadle, called a Lord Warden. Holding the office directly from the crown, I believe, all the royal emoluments incident to the Cinque Port territories become by assignment his. By some writers this office is called a sinecure.
