TEXAS. The term texas, in the western part of the United States, denotes the topmost structure on a river steamboat, located on the hurricane deck below or aft the pilothouse, which includes the officers' quarters and other rooms. It is derived from the fact that the staterooms on Mississippi River steamboats were named for states, and the officers' rooms, being the largest, were named texas. The word was in use by 1857, when Frederick L. Olmsteadqv used it in his Journey to Texas.
