“ All boisterous behavior, loud laughing and talking, are as reprehensible in the train as they are in the drawing-room. Composure of manner and a calm, easy grace distinguish the cultured traveler. He who is restless, excitable, fidgety, who talks in loud tones, walks back and forth to the water cooler many times, arranges and rearranges his belongings, is merely advertising to the other passengers in the train that he is traveling for the first time, and that he does not know how to conduct himself. ”
