the same or were separate deposits. To the south, a stone-lined drain, 0.25 m wide, was uncovered, running west then south. The drain defined an area of reddish sandy clay with flecks of charcoal, possibly a floor surface, which ended abruptly at its south side, where it was replaced by a deposit of pale brown clay silt, probably the fill of a cut. No archaeological deposits were noted on Plots 5 and 6, with the exception of a single feature cut into the subsoil, which was partially sectioned by one of the new foundation trenches. This feature was circular in shape, 0.6 m in diameter, with very steep sides, and was filled with dark grey silty clay. Edith Evans, Martin Locock and Richard Roberts Glamorgan-Gwent Archaeological Trust (Contracts Division) MARGAM ABBEY, NEATH PORT TALBOT (SS 803 863) An evaluation was carried out at Margam Abbey for Neath Port Talbot County Borough Council, in order to assess the likely effect of proposed landscaping works to enhance the appearance of the Scheduled Ancient Monument. These works included the construction of new pathways, the installation of seats and display boards, the construction of structures in the location of the high altar and abbot's chair, and the marking of missing monastic walls by hedging. Six trenches were excavated to establish the depth at which archaeological deposits survived intact. In all cases, undisturbed deposits were encountered within 0.20 m of the surface, and the foundations of the east wall of the presbytery and the northern end of the west wall of the north range were located. A trench across the west wall of the east range to the south of the Chapter House encountered a large well-built stone culvert, possibly part of the same feature located by a 1978 watching brief in the cloister. The culvert was probably rebuilt in the eighteenth century, perhaps replacing a medieval monastic structure. Martin Locock Glamorgan-Gwent Archaeological Trust (Contracts Division) THE OLD POST OFFICE, MAWDLAM, BRIDGEND (SS 807 819) A watching brief was carried out during topsoil stripping prior to the construction of a new bungalow on land adjacent to the Old Post Office in Mawdlam. The site lies in the middle of the village, close to
