In Africa there are stories that people who live in the deserts use monkeys to locate sources of water. They trap the monkeys, lure the animals to lick salt in order to make them feel thirsty. The people would release the monkeys after a while. The thirsty people would run after the thirsty monkeys which would apparently run towards the direction of sources of water to drink. Monkeys are water loving animals. Therefore, they live in areas where they can find water with ease.
