If a caller wishes to be very formal, she leaves a card for every lady in the family on whom she wishes to call.
In the beginning of the season a wife always leaves her husband's card with her own, and she usually does this also when making a call at the close of the season.
An unmarried woman calling on a married friend leaves only one card. If the friend has daughters or is entertaining a guest, a card may be left for each.
A lady always rises to receive a visitor.
It takes good judgment to know when to go, but it should be cultivated and practised. Lingering in taking one's leave is a great weariness, to one's hostess if not to one's self.
After a birth calls are made upon the mother after the child is a month old.
After a death the friends of the family should call in person inside of a month. The members of the family do not receive them, however, unless they wish to do so.
Social Calls of Men
A man never carries or leaves the cards of other men, nor can he leave cards for any of the women of his family.
A gentleman who calls on a lady's afternoon at home leaves in the card tray, on entering the house, a card for his hostess and one for his host. The card for his host must be left, even if that gentleman does not appear in the drawing-room, provided the caller is acquainted with him, and providing he is calling in acknowledgment of some hospitality recently received.
