At Temple Camp you may hear the story told of how Llewellyn, scout of the first class, and Orestes, winner of the merit badges for architecture and for music, were by their scouting skill and lore instrumental in solving a mystery and performing a great good turn. Yet if you should ask old Uncle Jeb Rushmore, beloved manager of the big scout camp, about these two scout heroes, a shrewd twinkle would appear in his eye and he would refer you to the boys, who would probably only laugh at you, for they are a bantering set at Temple Camp and would jolly the life out of Daniel Boone himself if that redoubtable woodsman were there.
