The "Necessary House, " otherwise known as an outhouse or toilet, is an essential part of the accommodations needed to set up a safe and efficient environment for the people who staff fire lookouts. They must be neither too close to nor too far from the lookout. In some areas, because of lack of space and/or rocky terrain, they are built over the edge of a cliff. While most are of wood construction, some are of stone, concrete, or man-made molded materials. This volume contains photos of outhouses along with photos of the lookouts they are paired with, and the surrounding environment. Also included is a short rhyme depicting some aspect of each site.
