In April 1994 CAT undertook a last minute watching brief during excavation work carried out at Bourne Mill to facilitate the ?unblocking of the west wall below the present ?penstock. The new excavation revealed a fresh area of the wall face to the north of that previously recorded during work in 1993. The following features were recorded: 1) Vertical stone jamb forming the northern side of the earlier leat inlet. By the time of recording the shape of the moulding was largely obscured by neatly laid brick blocking, but it appeared to be chamfered. 2) Two stone steps, 0.75m wide leading down towards the lower leat inlet. The east side of the steps butted against the main ?west wall. 3) A north-south wall of stone, brick and tile, adjoining the west side of the steps. 4) Well preserved wall facing incorporating flint ?gauvetting and generally consistent with that above ground level. (The report is handwritten and difficult to read) <1> A watching brief was held during works designed to prevent flooding in the cellar of Bourne Mill. The remedial works followed earlier trenching (see EVT3438). During the new work a 3 m wide trench was excavated against the leat inlet in the west wall of the mill, exposing the internal wall face to a depth of 1.75 m below the local ground level. Features observed appeared to represent a sequence of relatively late repairs and alterations. <1>
