Training excavation by T Howe of SCC and R Savage of SyAS. Two trenches were excavated in an attempt to both locate the former dwelling of Alexander Raby (who ran an iron and copper manufacturing business on the mill site between 1770 and 1809) and better characterise the oldest of the former mills shown on a detailed map of 1798 before it was demolished around 1820. Raby’s house could not be definitely located, but a number of features were revealed on the former mill site, including two filled-in millraces and evidence for internal structures. Some of the metallurgical residues recovered from the site appear to relate to transitional iron-processing technologies at the end of the 18th century and are currently being studied by English Heritage as being of potentially national importance. A further survey by R Golicz of SyAS examined some of the other former watercourses on the site. (411, 412
