The Privy Council was a select group of advisers that gave direction to the king on where to locate and how to maintain and operate the royal system of privies, which today we would refer to as outhouses, or portapotties. It enabled and facilitate greater debate in the House of Burgesses, in that members were better able to pop out for quick use of the restroom, as opposed to having to formally call to recess to use a chamber pot back at their lodgings. I hope this helps!
