EVERY ship that goes down is to some ex- tent a treasure ship. Her purser is in charge of much money, and her passengers carry valu- ables. Fortunes have been lost in trying to raise sunken treasure, but not until Menotte Nanni appeared on the scene did any one think of preventing the treasure from sinking, whatever hap- pened to the ship.

The two lower safes serve as a repository for registered mail and for the most precious part of the ship's cargo.
Ready ac- cess is gained to the safes through doors pro- vided in both the outer and inner casings at the various decks. Thus the first class passengers, for instance, could place their valua- bles in the safe at night and remove them in the morning. Of course there
