SPALDING SUGARBEET FACTORY OPENED IN ABOUT 1926. DURING ITS CONSTRUCTION EVIDENCE OF SALTMAKING WAS FOUND. INFORMATION WAS PASSED TO HILARY HEALEY BY J C MOSSOP. HE WAS OF THE OPINION THAT IT MIGHT HAVE BEEN ROMAN SINCE ROMANO-BRITISH POTTERY HAD BEEN FOUND NOT FAR AWAY IN OAKLEIGH DRIVE. IN VIEW OF THE LOCATION NEAR MEDIEVAL SLAT MOUNDS ON PINCHBECK MARSH IT COULD EQUALLY HAVE BEEN MEDIEVAL. {1}
