A fine Australian clipper is seized by the crew; the passengers are
landed on one desert island, the captain and a junior officer on
another; and the young hero of the story is kept on board to navigate
the ship. The mutineers refit the ship as a pirate vessel at an island
which affords them convenient shelter, and in which Ned makes the
discovery of an old-world treasure-hoard. At length, with the aid of a
repentant member of the crew, Ned succeeds in carrying off the ship. In
the meantime the captain and his associates have succeeded in rejoining
the passengers, and they are after many adventures found by Ned.
