Turning Down the Corners.
This custom is almost out of date, and in consequence of the various interpretations liable to be given to the act, its disuse is a satisfaction to all parties concerned. To briefly explain the custom, a card turned down at the corner, or across one end, signifies that the call was made in person, and is sometimes very convenient when one wishes it distinctly understood that the card was brought in person, not sent; while one folded through the center denotes that the call includes all members of the family. A man should not turn down the corners of his cards.
Minor interpretations, such as which end or which corner is to be turned down on different occasions, even the surviving adherents of the custom do not pretend to agree upon.
How to Leave Cards.
In leaving cards follow the fashion of those who have paid you the same courtesy. If a call has been made upon you, return it by a call, as to return a personal visit by the sending of a bit of pasteboard would partake of the nature of a slight. If cards only have been sent you by a servant, return cards in the same manner by messenger or servant; if they were sent by mail, return by mail. If the cards of any of the gentlemen of a house are left, always leave the cards of any gentleman of your family in return.
Of course first calls should be made and returned in person, the card-leaving formalities coming later on. This rule is departed from only by a few ladies whom age, health, social or literary duties will excuse from making personal calls. These frequently permit themselves to send out cards in place of a first call, either accompanying them with, or immediately following them by an invitation to some entertainment. This attention should receive the same notice as a first call; cards should be sent in return, together with an answer to the invitation, if it is of a nature to require it, and a personal call must be made thereafter, unless it was simply an afternoon tea, and an invitation sent in return speedily as possible.
A lady leaves a card for a lady only, a gentleman leaves cards for the host and hostess of a house. Some authorities assert that a man making the first call of ceremony should, in addition to the first-mentioned cards, if none of the family are at home, leave another folded down through the center for the other members of the family. The folding, however, is questionable taste and the requisite number of cards would be better left in their original state. Cards should be left for the daughters of a house; if there are sons, a lady may leave one of her husband's for them also.
Number of Cards to be Left.
After this first visit of ceremony it is only necessary to leave one card at any following call throughout the season. As a rule in country towns but one card is left at any call, unless it is at the first calls of a bride, when, if her husband's name is not engraved upon her card, she leaves one of his with her own.
A gentleman and lady calling together and finding the mistress of the house, only, at home, would leave but one card, that of the gentleman for the master of the house. Finding no one at home, they would leave three cards, one of hers and two of his. A lady calling under the same circumstances would leave one of her own cards and two of her husband's.
