All lines other than plain ones must be mentioned in the blazon in immediate connexion with the objects to which they refer and before the tincture, as, Gules a bordure engrailed Or. As the only party line that appears to face in one direction, engrailed follows the general heraldic feeling in turning its point to the dexter or to the chief unless there is special reason to the contrary. Invected is engrailed reversed, so that the points turn inward. Its use is comparatively rare and the effect is not very pleasing. In wavy any form of regular undulation may be employed so long as there is no possibility of confusion with nebulée. Nebulée is usually drawn in some modification of the two forms given above, but there is an old and interesting treatment in which a nearer, though still conventional, suggestion of clouds covers the ordinary, as in Fig. 72. This is a bordure nebuly equally with that drawn in the ordinary way. [Illustration: FIG. 72.] Indented is composed of small serrations, while Dancettée usually consists of not more than three chevrons which, in the case of a fess, for instance, may be complete, or the series may begin and end with a half chevron as in the example. In early instances the angles are very acute, and in the case of party lines extend well across the field. In such a case the line should begin on one side of the shield and finish on the other in order to equalize the direction of the points. Embattled, when applied to fesses and chevrons, is confined to the upper line unless the ordinary is blazoned “embattled counter embattled,” in which case both lines are similarly treated. When applied to a chevron the sides of the crenellations are usually kept vertical, as though in the wall of a sloping way, rather than at right angles to the ordinary, though the latter form also occurs. Raguly, especially when applied to a fess or a pale, is suggestive of stumps of branches that have been lopped from the parent stem, and this probably indicates its origin. Thus the projections on both sides of the ordinary slope the same way, and, in many examples, they alternate. In the case of a cross they point along the limbs outwards from the centre. Many of the heraldic lines are of very ancient usage, and the popular idea that they are signs of modernity is quite an erroneous one, some of them occurring as early as the reign of Edward I. A line is Rompu when it is interrupted as in Fig. 62, and an instance of this occurs in the Arms of Allen, which is per bend rompu. SUB-ORDINARIES.--The Canton, Gyron, Inescutcheon, Orle, Tressure, Bordure and Flanches are classed as Sub-ordinaries. The fusil or lozenge (_q.v._) and some others are also sometimes included in this division, but classification of this kind is of little practical importance.
