This document sets out the results from archaeological works carried out at Fernhurst Furnace, Fernhurst, West Sussex. The near vertical section of the south side of the tail-race was cleaned and recorded in order to compare its condition and stratigraphy with a similar recording exercise carried out during archaeological works in 1989 and 1992. The results indicate that the deposits on the south side of the tail-race have not suffered the damage evident to those feature lying below, within the race itself, probably due to the protection offered by their height and vegetation cover. The stratigraphy exposed enabled further conclusions to be drawn about the nature of the deposits in this location, with the tentative conclusion drawn that the structures visible relate to a mid-18th century covered area for works relating to the production of cannon. The hope is expressed that further work will be undertaken in order to better understand this important phase of the furnace's operation.
