jambs across to the buttresses, as is the case with those of the doorway. The billet-moulded sill evidently passed round the tower completely, before the addition of the angle buttresses, since it appears again on the north buttress of the west front of the same tower; and the obvious inference is that there was once a window also on the west in this same stage at the same level. The window immediately below the upper division of the tower is of the same date and character exactly as the one on the west in the like place; and it should be noticed that the sills of the upper windows run on as string-courses, which are continued round the circular angle-shafts of the buttresses. Passing eastward from the tower, the external #Roof# of the nave becomes visible. The irregularly waved line of the ridge where the lead rolls meet, as it were, against the sky, is a pretty indication of the presence of the aged timbers underneath that support it above the walls. The oldest part of the building to be seen from this point is the strip of walling at the clerestory level. The twelfth-century round-arched windows are there almost complete. In detail they are like those of the tower. Two of them, those in the fourth and fifth bays from the tower, have had later work inserted in the same openings. The crest of the wall between the west and the central tower was renewed in the fourteenth century. It consists of a parapet with a weathered coping for the top course of stonework, so that the water might not rest upon it and percolate through the walls. Three courses below this is a simply moulded string-course, and immediately beneath is the cusped arcade supported on the course of detached moulded and shaped corbels. For five feet below the bottom of the corbels the newer part of the wall is continued. It will be interesting later to notice the way in which the parapet on the north side of the nave has been dealt with. The reason for the presence of so much new walling at this level is no doubt to be found in the fact that the roof timbers at the time of the second fire were carried down over the walls.
