Three small trenches were cut to intercept the drain line along the outside of the south aisle wall of St James' church, which had become blocked, and to examine its condition. All three trenches located the underground ceramic pipe into which the surface channel drained. In Trench 1, the detailed working of the drain was revealed. The perforations in the stone surface channel marked the position of an underground brick sump, approximately 500m x 500m and six courses (450m) deep. A pipe led down and southwards from the brick sump to a connecting drain. No burials were disturbed during the work, although there was a quantity of loose human bone which was reburied in the trenches at the end of the work. Two of the trenches showed graveyard soil cut by the modern drain. The other (Trench 2) revealed the outer face of the south aisle wall, and the face of one of the buttresses.<1>
