 The girls learn their positions (based on their height, and thus changing from year to year and needing to be re-learned) and move in time to the music from one point to the next.The end of the performance is marked by the girls producing the Masonic emblem of set square and compass, and the point, the smallest child in the performance marching forward alone to complete the symbol.Duos and Trios are a tradition upheld at prize day.
