the arms of the Crown Prince. In Italian heraldry, although differences are known, there is no system whatever. In Spain and Portugal marks of cadency, in our sense of the word, are almost unknown, but nevertheless the bordure, especially as indicating descent from a maternal ancestor, is very largely employed. The most familiar instance is afforded by the Royal Arms of Portugal, in which the arms of Portugal are surrounded by a "bordure" of Castile.
Differencing, however, had become a necessity at an earlier period than the period at which we find an approach to the systematic usage of the label, bordure, and bend, but it should be noticed that those who wished, and needed, to difference were those younger members of the family who by settlement, or marriage, had themselves become lords of other estates, and heads of distinct houses. For a man must be taken as a "Head of a House" for all intents and purposes as soon as by his possession of lands "held in chief" he became himself liable to the Crown to provide stated military service, and as a consequence found the necessity for a banner of arms, under which his men could be mustered. Now having these positions as overlords, the inducement was rather to set up arms for themselves than to pose merely as cadets of other families, and there can be no doubt whatever that at the earliest period, differencing, for the above reason, took the form of and was meant as a change in the arms. It was something quite beyond and apart from the mere condition of a right to recognised arms, with an indication thereupon that the bearer was not the person chiefly entitled to the display of that particular coat. We therefore find cadets bearing the arms of their house with the tincture changed, with subsidiary charges introduced, or with some similar radical alteration made. Such coats should properly be considered essentially different coats, merely indicating in their design a given relationship rather than as the same coat regularly differenced by rule to indicate cadency. For instance, the three original branches of the Conyers family bear: "Azure, a maunch ermine; azure, a maunch or; azure, a maunch ermine debruised by a bendlet gules." The coat differenced by the bend, of course, stands self-confessed as a differenced coat, but it is by no means certain, nor is it known whether "azure, a maunch ermine," or "azure, a maunch or" indicates the original Conyers arms, for the very simple reason that it is now impossible to definitely prove which branch supplies the true head of the family. It is known that a wicked uncle intervened, and usurped the estates to the detriment of the nephew and heir, but whether the uncle usurped the arms with the estates, or whether the heir changed his arms when settled on the other lands to which he migrated, there is now no means of ascertaining.
Similarly we find the Darcy arms ["Argent, three cinquefoils gules,"
