The Ladies' Book of Etiquette, and Manual of Politeness

Remember that a lady-like deportment is always modest and quiet. If you meet a friend at table, and converse, let it be in a tone of voice sufficiently loud for him to hear, but not loud enough to reach ears for which the remarks are not intended. A boisterous, loud voice, loud laughter, and bold deportment, at a hotel, are sure signs of vulgar breeding. When you have finished your meal, cross the room quietly; if you go into the parlor, do not attract attention by a hasty entrance, or forward manner, but take the seat you may select, quietly. The acquaintances made in a hotel may be dropped afterwards, if desirable, without rudeness, and a pleasant greeting to other ladies whom you may recognize from meeting them in the entries or at table, is courteous and well-bred; be careful, however, not to force attentions where you see they are not agreeably received. A lady's dress, when alone at a hotel, should be of the most modest kind. At breakfast let her wear a close, morning dress, and never, even at supper, appear alone at the table with bare arms or neck. If she comes in late from the opera or a party, in full dress, she should not come into the supper-room, unless her escort accompanies her. A traveling or walking-dress can be worn with perfect propriety, at any meal at a hotel, as it is usually travelers who are the guests at the table. After breakfast, pass an hour or two in the parlor, unless you are going out, whilst the chambermaid puts your room in order. You should, before leaving the room, lock your trunk, and be careful not to leave money or trinkets lying about. When you go out, lock your door, and give the key to the servant to hand to the clerk of the office, who will give it to you when you return. You may do this, even if you leave the room in disorder, as the chambermaids all carry duplicate keys, and can easily enter your room in your absence to arrange it. The door should not be left open, as dishonest persons, passing along the entry, could enter without fear of being questioned.
