The weather was remarkably fine, and the sea smooth, as the wind was off shore.  We were generally in sight of the cliffs, which extend along the coast, and had occasional glimpses of blue mountains beyond, Snowdon towering above them all, with the Isle of Anglesea on our port side, and the county of Caernarvon on the starboard.  After passing the entrance, the Straits widen out into a lake-like expanse; but the shores again close in where the town of Caernarvon is situated.
