A pale embattled is embattled upon both its edges; a fess embattled is embattled only upon the upper edge; a chief is embattled necessarily only upon the lower; and the grave difficulty of distinguishing "per pale engrailed" from "per pale invected" shows that no rigid rules can be laid down. When we come to sub-ordinaries, the confusion is still more apparent, for as far as I can see the only reason for the classification is the tabulating of rules concerning the lines of partition. The bordure and the orle can be, and often are, engrailed or embattled; the fret, the lozenge, the fusil, the mascle, the rustre, the flanche, the roundel, the billet, the label, the pairle, it would be practically impossible to meddle with; and all these figures have at some time or another, and by some writer or other, been included amongst either the ordinaries or the sub-ordinaries. In fact there is no one quality which these charges possess in common which is not equally possessed by scores of other well-known charges, and there is no particular reason why a certain set should be selected and dignified by the name of ordinaries; nor are there any rules relating to ordinaries which require the selection of a certain number of figures, or of any figures to be controlled by those rules, with one exception. The exception is to be found not in the rules governing the ordinaries, but in the rules of blazon. After the field has been specified, the principal charge must be mentioned first, and no charge can take precedence of a bend, fess, pale, pile, chevron, cross, or saltire, except one of themselves. If there be any reason for a subdivision those charges must stand by themselves, and might be termed the honourable ordinaries, but I can see no reason for treating the chief, the quarter, the canton, gyron, flanche, label, orle, tressure, fret, inescutcheon, chaplet, bordure, lozenge, fusil, mascle, rustre, roundel, billet, label, shakefork, and pairle, as other than ordinary charges. They certainly are purely heraldic, and each has its own special rules, but so in heraldry have the lion, griffin, and deer. Here is the complete list of the so-called ordinaries and sub-ordinaries: The bend; fess; bar; chief; pale; chevron; cross; saltire; pile; pairle, shakefork or pall; quarter; canton; gyron; bordure; orle; tressure; flanche; label, fret; inescutcheon; chaplet; lozenge; fusil; mascle; rustre; roundel; billet, together with the diminutives of such of these as are in use.
