A chief is never couped or cottised, and it has no diminutive in British armory. THE QUARTER The quarter is not often met with in English armory, the best-known instance being the well-known coat of Shirley, Earl Ferrers, viz: Paly of six or and azure, a quarter ermine. The arms of the Earls of Richmond (Fig. 204) supply another instance. Of course as a division of the field under the blazon of "quarterly" (_e.g._ or and azure) it is constantly to be met with, but a single quarter is rare. Originally a single quarter was drawn to contain the full fourth part of the shield, but with the more modern tendency to reduce the size of all charges, its area has been somewhat diminished. Whilst a quarter will only be found within a plain partition line, a field divided quarterly (occasionally, but I think hardly so correctly, termed "per cross") is not so limited. Examples of quarterly fields will be found in the historic shield of De Vere (Fig. 205) and De Mandeville. An irregular partition line is often introduced in a new grant to conjoin quarterings {135} borne without authority into one single coat. The diminutive of the quarter is the canton (Fig. 206), and the diminutive of that the chequer of a chequy field (Fig. 207). THE CANTON [Illustration: FIG. 206.--Canton.] The canton is supposed to occupy one-third of the chief, and that being supposed to occupy one-third of the field, a simple arithmetical sum gives us one-ninth of the field as the theoretical area of the canton. Curiously enough, the canton to a certain extent gives us a confirmation of these ancient proportions, inasmuch as all ancient drawings containing both a fess and a canton depict these conjoined. This will be seen in the Garter plate of Earl Rivers. In modern days, however, it is very seldom that the canton will be depicted of such a size, though in cases where, as in the arms of Boothby, it forms the only charge, it is even nowadays drawn to closely approximate to its theoretical area of one-ninth of the field. It may be remarked here perhaps that, owing to the fact that there are but few instances in which the quarter or the canton have been used as the sole or principal charge, a coat of arms in which these are employed would be granted with fewer of the modern bedevilments than would a coat with a chevron for example. I know of no instance in modern times in which a quarter, when figuring as a charge, or a canton have been subject to the usual lines of partition. The canton (with the single exception of the bordure, when used as a mark of cadency or distinction) is superimposed _over_ every other charge or ordinary, no matter what this may be. Theoretically the canton is supposed to be always a later addition to the coat, and even though a charge may be altogether hidden or "absconded" by the canton, the charge is always presumed to be there, and is mentioned in the blazon.
