“ In blazoning, all tautology must be particularly avoided. Never repeat a tincture twice in the same blazon. Should it occur again, it must be described as of the first (or field) , of the second, of the last, &c., as the case may be. At the same time, everything must be described with the utmost minuteness, so that a person, by reading the blazon, may be able to delineate the shield and its charges with unerring precision. ”
