The Scout badge is shaped like a north point on an old compass. Te design is also known as a trefoil (a flower with three leaves) or a fleur-de-lis (the French name for an iris flower). It is the basic shape of the badges worn by Scouts in other countries as well.
The shape of the Scout badge signifies a Scout's ability to point the right way in life just as a compass does in the wilderness. The three points of the trefoil, like the three raised fingers of the Scout sign, represents the three parts of te Scout Oath -- duty to God and country, duty to others, and duty to yourself.
