A well and a water house in the desert on the way through the Wadi Hadramaut. The well was already dry. Thus, the water house still contained a goat pelt bag filled with water. Someone in the region must have been responsible for the water house. Every traveller is allowed to use the water for free. The water bag is cooled by wind through the grid and over the wet pelt. This kind of service we find nearly in all northern African and southern Asian countries.
