idi ation . ▁However , ▁a ▁notable ▁exception ▁to ▁this ▁rule ▁can ▁be ▁seen ▁in ▁the ▁arms ▁of ▁Thomas ▁de ▁Holland , ▁Duke ▁of ▁Sur rey ▁( a ▁nep hew ▁of ▁Richard ▁II ) ▁from ▁a ▁drawing ▁of ▁his ▁se al , ▁ 1 3 9 9 , ▁showing ▁a ▁differ encing ▁of ▁a ▁full ▁bord ure ▁er mine , ▁and ▁a ▁full ▁bord ure ▁argent . ▁ ▁A ▁chief ▁over lies ▁a ▁bord ure , ▁unless ▁the ▁bord ure ▁is ▁added ▁to ▁a ▁coat ▁that ▁previously ▁included ▁a ▁chief , ▁or ▁so ▁it ▁is ▁often ▁said . ▁In ▁practice , ▁the ▁order ▁in ▁which ▁things ▁are ▁to ▁over lie ▁each ▁other ▁can ▁usually ▁be ▁infer red ▁from ▁the ▁bla zon . ▁ ▁For ▁example , ▁in ▁the ▁arms ▁of ▁Am ber ▁Valley ▁Bor ough ▁Council , ▁the ▁bla zon ▁describes ▁the ▁bord ure ▁before ▁the ▁chief , ▁and ▁the ▁bord ure ▁does ▁not ▁surr ound ▁the ▁chief ; ▁while ▁in ▁the ▁arms ▁of ▁the ▁British ▁Columbia ▁Institute ▁of ▁Technology , ▁the ▁bla zon ▁spec ifies ▁a ▁chief ▁... ▁within ▁a ▁bord ure . ▁ ▁Like ▁any ▁ordinary ▁or ▁other ▁charge , ▁a ▁bord ure ▁may ▁be ▁of ▁a ▁single ▁plain ▁t inct ure ▁or ▁divided . ▁ ▁Like ▁any ▁ordinary , ▁it ▁may ▁be ▁smooth ▁or ▁subject ed ▁to ▁any ▁of ▁the ▁lines ▁of ▁variation ; ▁it ▁may ▁form ▁a ▁field ▁for ▁other ▁charges . ▁ ▁These ▁variations ▁are ▁effectively ▁explo ited ▁in ▁the ▁Scottish ▁system ▁of ▁cad ency . ▁ ▁Since
