Jones owns a parcel of land one thousand foot square which has old irons at the 4 corners. Jones sells to Eastman the eastern 500’ in 1960. A survey is performed at the time of the sale and irons are set 500’ west of the east line in the front and back. The deed reads, “the eastern 500’ of Jones’ land”. In 1985 Jones sells the remainder to Westerly. The deed reads “the western 500’ of Jones’ land”. No survey is performed but the 1960 irons are pointed out to Westerly. In 1995 Eastman sells to Mr. NewYoung. A year later a survey is performed to erect a fence. All irons are found. The irons set in 1960 are found to be 996’ west of the east line. Where is the property line?
