Year after year the soil had been planted to the same crop. It was farmed by uneducated and careless slaves, and the planters knew little about soil conservation.

It is a dream laboratory where researchers are at work studying dreamers. Their findings have revealed that everyone dreams from three to seven times a night, although in ordinary life a person may remember none or only one of his dreams. While the subjects-usually students-are asleep, special machines record their brain waves and eye movements as well as the body movements that signal the end of a dream. Surprisingly, all subjects sleep soundly. Observers report that a person usually moves his body restlessly before a dream. Once the dream has started, his body relaxes and his eyes become more active, as if the curtain had gone up on a show. As soon as the machine indicates that the dream is over, a buzzer wakens the sleeper. He sits up, records his dream, and goes back to sleep-perhaps to dream some more.
