H E HALLAM EQUATES QUADRING BANK WITH OLD FENDIKE NOTED IN HISTORICAL SOURCES AND RECORDS ITS EARLIEST APPEARANCE IN DOCUMENTS AS THE C13, BUT ELSEWHERE HE SPECULATES ON A PRE-852 AD DATE. EVIDENCE WOULD SUGGEST THAT THIS UNDOUBTED BANK, WHICH PROTECTED AN AREA FROM WEST OF SPALDING TO DONINGTON, WAS NOT FORMED IN ONE MAJOR CONSTRUCTION PHASE AND THEREFORE MAY NOT BE OF ONE DATE. SIMILARLY THE NEW FENDIKE, AGAIN WITH C13 REFERENCES IN DIFFERENT IN CHARACTER IN QUADRING FROM THAT FURTHER SOUTH. SCATTERED FINDS OF MEDIEVAL POTTERY, WHICH MIGHT SUGGEST ARABLE USE OF THE LAND ARE RARE BETWEEN THESE TWO BANKS. {1}
