+The ship drew on and had safely passed the strait, which some volcanic shock
+has made between the Calasareigne and Jaros islands; had doubled Pomegue, and
+approached the harbor under topsails, jib, and spanker, but so slowly and
+sedately that the idlers, with that instinct which is the forerunner of evil,
+asked one another what misfortune could have happened on board. However, those
+experienced in navigation saw plainly that if any accident had occurred, it was
+not to the vessel herself, for she bore down with all the evidence of being
+skilfully handled, the anchor a-cockbill, the jib-boom guys already eased off,
+and standing by the side of the pilot, who was steering the Pharaon towards the
+narrow entrance of the inner port, was a young man, who, with activity and
+vigilant eye, watched every motion of the ship, and repeated each direction of
+the pilot.
