It was necessary to extend the size of this trench (to the north) when an unrecorded vault (context 419) was discovered at the south end. This vault had been partly truncated by a later brick retaining wall, built at the beginning of this century (context 406). The vault, which was divided into compartments, had been partially back-filled at this time and contained at least one burial, still in situ. However, full excavation of the north end of the vault was not possible due to lack of space for shoring. In the area which was investigated the undisturbed sand and gravel (context 441) was located at a depth of 2.0m below the then ground level. Overlying the natural was a sequence of sand deposits (context 440) (context 439) (context 438) (context 437) (context 435). No finds were discovered and the deposits were believed to be hill wash. In the remaining area of the northern extension, four intercutting graves – none of which contained any coffin fittings – were cut into the top of the sand. For safety reasons it was only possible to excavate to a depth of 1.2m into what appeared to be grave fills. At this depth a large ceramic pipe [aligned E-W] (context 425) was found running through this part of the trench; the use of which was unknown, but it was generally supposed to be a land drain.
