 at two sides to sea breezes. Crew quarters, too, are air-conditioned. 



An interesting feature of the new ships is the extensive use of alumi-

 corrosion by sea water. The stack and the two upper decks of the super- 

 structure are of aluminum. This material is also used in lifeboats, hatch 

 covers, awning stanchions, accommodation ladders, air ports and covers, 

 deck and ladder treads and windows. Directional signs for passenger use 

 and many interior decorative features are also of aluminum.

 through improved facilities and efficient operating methods. 



In the early '20's, the Aluminum Company of America had developed
