A gentleman, on entering a public carriage or omnibus, must never step before a lady, but stand aside until she enters, raising the hat slightly if she acknowledges his courtesy, as a true lady will, by a bow. He may offer to assist her if she appears to need it, even if she is a perfect stranger to him. If a gentleman consents to act as escort to a lady, he must carefully fulfill all the requirements of that rather arduous position. If she meets him at a wharf or depot, he must be a little before the hour for starting, to procure her ticket, check her baggage, and secure for her a pleasant seat. He must never leave her to stand in an office or upon a wharf whilst he attends to her tickets and baggage; but, having seen her comfortably seated in a ladies' room or cabin, return for those duties. In arriving at a station, he must see her seated in a hack before he attends to the trunks. In a hotel, the gentleman must escort the lady to the parlor before securing her room, but not detain her afterwards. However agreeable she may be, he may be certain she is longing to rest after her journey, and remove the travel stains from her face and dress. He must at once escort her to her room, ascertain what hour it will be agreeable for her take the next meal, and meet her again in the parlor at that hour. He must not leave her upon arriving at the journey's end until he has escorted her to the house, and if he remains in the city, he must call the next day to inquire after her health. After that, the lady may continue the acquaintance or not, as she pleases; but if she declines to do so, by nonrecognition at the next meeting, he is at liberty to decline acting in the capacity of escort to her again. A gentleman who is travelling alone may offer little courtesies to strangers, and even to ladies, carefully maintaining a respectful manner, that may assure them they need not fear to encourage impertinence by accepting the proferred civilities. In travelling abroad, the truest courtesy is to observe as far as practicable every national prejudice. The old proverb, to "do in Rome as Romans do," is the best rule of etiquette in foreign travel. The man who affects a supercilious disdain for all foreign customs and forms will not convince the natives of his vast superiority, but impress them with the belief that he is an ill- bred idiot. The most polite, as well as agreeable travellers are those who will smilingly devour mouse-pie and bird's-nest soup in China, dine contentedly upon horse-steak in Paris, swallow their beef uncooked in Germany, maintain an unwinking gravity over the hottest curry in India, smoke their hookah gratefully in Turkey, mount an elephant in Ceylon, and, in short, conform gracefully to any native custom, however strange it may appear to him.
