The flattened wheat formed(形成)a circle about six meters across . Around this circle were four smaller circles of flattened wheat.

　　Three years later a farmer who lived nearby discovered almost the same circles in one of his fields. These circles were larger—nearly 15 meters across. That same year, another English farmer discovered three circles of flattened wheat on his land—one large circle between two small circles . During the following years, farmers in England found circles in their fields more and more often.
