On the floor above the scene is as animated, but of a different character. Every one here is in full dinner dress, and all are on their good behaviour. The grand dining-room is crowded with guests, who are doing ample justice to the sumptuous viands set before them. The parlors are thronged with ladies and gentlemen, and the corridors are filled with promenaders. The toilettes of the ladies are magnificent, and they can be seen here to better advantage than at any ball or evening party. You may see here some of the loveliest and most refined women, and some of the coarsest and vulgarest, some of the most courtly gentlemen, and some of the most insufferable snobs. If you will join the quiet-looking man moving through the throng as if seeking some one whom he cannot find, he can give you many an interesting bit of gossip about the various persons whom you will encounter in your walk. He is the detective of the house, and is on the watch for improper characters. Well-dressed thieves will make their way into hotels in spite of the precautions of the proprietors. Here a guest is comparatively safe. The detective is argus-eyed, and knows everybody. Let a pick-pocket or thief but show his face in this place, and his arrest is sure. All night the corridors are patrolled by watchmen to make sure of the safety of the sleeping guests. The house is absolutely fire-proof. The cost of conducting such an establishment is immense, but the profits are in proportion. The average profit of this house is said to be about a quarter of a million of dollars per annum. The hotels that have been mentioned are all conducted on the American plan of full board, or one charge for every expense. This enables a guest to calculate his expenses exactly, and has many other advantages. Many of the most fashionable houses are conducted on what is called "the European plan," in which a separate charge is made for room, meals, and every service rendered. It is said that this is more economical than the other plan, and that it is less profitable to the proprietors. It is adopted by the Hoffman, St. Denis, Glenham, Brevoort, Coleman, St. James, Albemarle, Clarendon, Everett, Grand, Gilsey, and several other prominent houses.
