ch is
about six inches in depth. If is not possible to state more concerning
these parts in detail, since they have been much repaired at various
times.

The stove-pipes which run up the north and south sides of the nave as
smoke-flues for the heating-apparatus do not add to the beauty of the
exterior.

In the fifth bay, eastward from the south-west tower, is the #South
Porch#, which opens directly into the west walk of the cloister.
Early in the nineteenth century it was in a ruinous condition; but
restoration has again given it stability, if not all its old beauty.
The idea of the design, as it is seen from the cloister, is identical
with that of the exterior of the west porch. But in the detail of its
mouldings and other features it is different entirely. The restored
abaci of the capitals, like the originals, are some of them square,
others irregular octagons. The interior is vaulted, and has diagonal
and wall ribs. On the west and east sides are stone benches. But the
west side has in addition a small arcade of four arches forming
recessed sedilia. The mouldings to the arches of this small arcade are
of about the same date as those in the two outer orders of the
enclosing arch on the south front of this porch. The two smaller
arches under it appear to be later work, if we judge from their
present character. But the arch-mould of the #Doorway# within the
porch is work of approximately the same date as the outer moulded
member of the enclosing arch on the west front of the west porch. The
enclosing arch of the south porch is later work than these. But the
two inner moulded orders of the enclosing arch of the west porch are
even later still in character.

The east side of this south porch forms the west wall of the present
choir singing school--the old sacristy. But this room projects farther
southward than the porch. The limit of its projection is indicated by
a portion of a buttress in the cloister. Between this buttress and the
porch are two small windows--one of them is now blocked up. The upper
one is the same in design as those others on the south side of the
same apartment. These we shall consider presently. Above the central
pier at the entrance to this porch is a miserable figure in stone,
intended to represent a saint.
