Vessels of the largest class now draw only as much water as the smallest drew a few years ago, four feet five inches being regarded as the _maximum_. It appears from the following table that the average length of these prodigious floating hotels is above 300 feet; some of them approaching 400. In the passenger accommodation afforded by them no water communication in any country can compete. Nothing can exceed the splendor and luxury with which they are fitted up, furnished, and decorated. Silk, velvet, the most costly carpetings and upholstery, vast mirrors, gilding, and carving, are profusely displayed in their decoration. Even the engine-room in some of them is lined with mirrors. In the Alida, for example, the end of the engine-room is one vast mirror, in which the movements of the brilliant and highly-finished machinery are reflected. All the largest class are capable of running from twenty to twenty-two miles an hour, and average nearly twenty miles without difficulty. In the annexed table are exhibited the details of ten of the most recently constructed passenger vessels:--
