As you return from the east, continues the historian of the Abbey, you are struck with two windows in the Bell-tower on the south side, in the second story. They consist of a round-headed arch, divided into two lights by a sturdy _balustre_, standing in the middle of the wall, and extending from its plinth to its capital, right through the centre to the top of the arch. Beyond this, in the thickness of the wall, vestiges of a passage are discovered, which seems to have formed a gallery round the tower. A round-headed plain Norman door, the jambs being low pillars with cushion capitals, at the west end of the choir, on the south side, leads into <g>The Lady Chapel.</g> The slight remains of the corbels, from which the roof sprung, are here more elaborate in their work than in any other part of the building. We had some difficulty in tracing out the foundation. <g>The Chapter-house</g>[350] was built in contiguity to the south side of the south transept. On the north side of it a stable is inserted, which prevents accurate observation. In a calf-pen or shed, however, we discovered the corresponding base of the columns to the other unencumbered side. It seems to have been a spacious and elegant room, of an oblong form, lighted at the east and at the south, where there is a deep recess, and traces sufficient to warrant the surmise that there were three Norman windows on that side. The south wall is ornamented and divided into four compartments by clusters of triple pillars, upon which the roof rested. The east end narrows in, and the entrance is from the west. On the south of the church, between the transept and the Chapter-house, is an <g>Oratory</g>--the chapel already named--with an engroined roof in complete preservation. The central arch springs from a Norman corbel on each side, and two other arches form the angles of the building in the same manner. By their intersection the roof is formed. A deep Norman window is fixed in the east wall. The sides of the door consist of two pillars, capitals with flowers, and bases, ogee-shaped. South again of the chapter, a large space for a doorway--the side pillars of which are partly standing--opens into <g>The Refectory</g>, of which the slight traces still in existence, defy anything like accuracy of detail. A rude window, chimney, and vaults, broken in and filled with rubbish, show where the offices and kitchen lay. Beyond these is a splendid <g>Sewer</g>, which has been mistaken by the common people to be the commencement of a subterraneous passage leading to “Oldham Castle,” under the mountains. <g>The Vivarium</g>, or Fish-pond, is east of the church, and a mountain rill still runs through it. The whole of the conventual buildings, together with a close, amounting to seven acres, were surrounded by a wall. At some little distance south-west from the church, and divided from it by what is now a long meadow, stand
