The symbol used for the world jamboree is the Jacob's staff, which was used during the exploration of new territories in the Age of Discovery by Dutch sailors. The ten arms symbolize the ten articles of the Scout Law. After this jamboree the Jacob’s staff became the award of gratitude for the Netherlands Scout organizations. Wooden versions were given to scouts who had supported the jamboreen organisation. Later on, the silver and gold Jacob's staff became official awards of gratitude in the Dutch national scouts organision.
At the closure of the event on 1937-08-09, Baden-Powell pointed out the symbol of this jamboree: the Jacob's Staff and took his farewell.
I am nearing the end of my life. Most of you are at the beginning, and I want your lives to be happy and successful. You can make them so by doing your best to carry out the Scout Law all your days, whatever your station and wherever you are. Now goodbye. God bless you all. God bless you.
