When any charge is placed on an ordinary, as in Fig. [41], where three calves are charged upon the bend, if these charges are of the same colour as the field instead of repeating the name of the colour, it must be blazoned as being "of the field."

We now come to those charges known as "marks of cadency." They are also called "differences" or "distinctions."

Fig. 36.

Cadency—literally, "falling down"—means in heraldic language, "descending a scale," and is therefore a very suitable term for describing the descending degrees of a family. Thus "marks of cadency" are certain figures or devices which are employed in armorial bearings in order to mark the distinctions between the different members and branches of one and the same family. These marks are always smaller than other charges, and the herald is careful to place them where they do not interfere with the rest of the coat of arms. There are nine marks of cadency—generally only seven are quoted—so that in a family of nine sons, each son has his own special difference. The eldest son bears a label (Fig. [36], 1); the second, a crescent, (2); third, a mullet (3)—the heraldic term for the rowel of a spur[3]; the fourth, a martlet (4)—the heraldic swallow; the fifth, a roundle or ring (5); the sixth, a fleur-de-lys (6); the seventh, a rose (7); the eighth, a cross moline; and the ninth, a double quatrefoil. The single quatrefoil represents the heraldic primrose. There is much doubt as to why the label was chosen for the eldest son's badge, but though many writers interpret the symbolism of the other marks of cadency in various ways, most are agreed as to the meaning of the crescent, mullet, and martlet—viz., the crescent represents the double blessing which gives hope of future increase; the mullet implies that the third son must earn a position for himself by his own knightly deeds; whilst the martlet suggests that the younger son of a family must be content with a very small portion of land to rest upon. As regards the representation of the other charges, the writer once saw the following explanation in an old manuscript manual of French heraldry—namely: "The fifth son bears a ring, as he can only hope to enrich himself through marriage; the sixth, a fleur-de-lys, to represent the quiet, retired life of the student; the seventh, a rose, because he must learn to thrive and blossom amidst the thorns of hardships; the eighth, a cross, as a hint that he should take holy orders; whilst to the ninth son is assigned the double primrose, because he must needs dwell in the humble paths of life."

[3:] A mullet is generally represented as a star with five points, but if there are six or more, the number must be specified. It must also be stated if the mullet is pierced, so that the tincture of the field is shown through the opening.

Fig. 37.

The eldest son of a second son would charge his difference as eldest son, a label, upon his father's crescent (Fig. 37), to show that he was descended from the second son, all his brothers charging their own respective differences on their father's crescent also. Thus, each eldest son of all these sons in turn becomes head of his own particular branch.

When a coat of arms is charged with a mark of cadency, it is always mentioned last in blazoning, and is followed by the words, "for a difference." Thus Fig. [43] should be blazoned, "Or, kingfisher with his beak erected bendways[4] proper with a mullet for a difference gu.," thus showing that the arms are borne by a third son.
