What is an outhouse toilet?
This a small enclosed structure located out of doors. It has a deep hole dug into the ground and [typically] a wooden seat with a hole in the middle located above the hole. A person sits on the seat, and when finished, could sprinkle a scoop of lime into the hole to assist in breaking down solid material and controlling bad smell. In the U.S., a half moon is traditionally carved on the door to an outhouse.
