The Ladies' Book of Etiquette, and Manual of Politeness

If you see that another lady, though she may be an entire stranger, is losing her collar, or needs attention called to any disorder in her dress, speak to her in a low tone, and offer to assist her in remedying the difficulty. Be careful always in opening a door or raising a window in a public parlor, that you are not incommoding any one else. Never sit down to the piano uninvited, unless you are alone in the parlor. Do not take any book you may find in the room away from it. It is best always to carry writing materials with you, but if this is not convenient, you can always obtain them at the office. In a strange city it is best to provide yourself with a small map and guide book, that you may be able to find your way from the hotel to any given point, without troubling any one for directions. If you wish for a carriage, ring, and let the waiter order one for you. When leaving a hotel, if you have been there for several days, give the waiter at table, and the chambermaid, a fee, as your unprotected situation will probably call for many services out of their regular routine of duties. On leaving, ring, order your bill, pay it, state the time at which you wish to leave, and the train you will take to leave the city. Request a man to be sent, to carry your baggage to the hack; and if you require your next meal at an unusual hour, to be ready for your journey, order it then.
