We sighted Coquet Island, with its square white lighthouse, from which a light burst forth as we approached.  Near it were the castellated dwellings of the keepers, painted different colours.  In its neighbourhood are dangerous rocks, and over each a red ray is shown, to warn vessels which might otherwise run upon them.  We were now almost constantly in sight of some light, which enabled us to know our exact position.  Dick and I turned in while Coquet Island light still shone brightly.
