What are the proper rules of etiquette for a gentleman when calling upon a lady at her home? And what are the rules for leaving calling cards? A gentleman should call between the hours of two and six in the afternoon, on week days, and not later than ten in the evening, on Sundays. He should send up his card, and, if the lady be at home, he should be shown into the drawing-room. If she desires to see him, she will come down; if not, he must take leave, after a few minutes' conversation. In either case, he leaves one of his own cards, and takes none of the lady's. On parting, he may shake hands, if he pleases, but must not prolong his visit unnecessarily. He should not call oftner than once a fortnight, in the winter, and once a month, in the summer.
