gs a tiny shaft that carries the edge-roll of the arch; and the
lancet arches also, where they adjoin the solid piers between the bays,
have a shaft in the jamb. On all three walls the shafts in this storey
stand on a kind of kerb or parapet, which is interrupted in the middle
of each bay, and the stilt of the round arch is treated almost like a
classical entablature, and has a moulding or cornice above it, while the
uppermost part of the wall is thickened, thereby necessitating over each
bay a comprising arch, which on the north wall is round, but on the
other walls follows the shape of the three sub-arches, and forms a kind
of upper order to them.

The roof-shafts, which do not break the string-courses, spring from very
various levels: on the east side from the ground, and on the north side
from the unusually high level of the second string, while on the west
side one cluster rises from the first string and the other from above
the second string (having perhaps been shortened in the last case to
make way for the Perpendicular arch beneath). On the east and west walls
these shafts are of a thickness which, besides being out of proportion
to the other parts of the architecture, is structurally unnecessary, for
they do not directly support the roof at all, but end at the top of the
triforium in triple capitals, of which the central member is square and
the others round. Upon each of these capitals, stand three detached and
much thinner shafts--namely, that which really carried the roof-beams,
and those (adjacent to it) of the arches that carry the above-mentioned
thickening of the wall. Thus is afforded a striking instance of the
tendency, so often exemplified in Archbishop Roger's work, to use two
shafts, one on the top of the other, instead of prolonging one--a
tendency which marks the organic development of the style as still
incomplete. On the north wall the three shafts in each cluster are
carried up from their corbel to the top in one piece, unbroken save by a
band at the impost level of the triforium and another at the third
string, and they seem detached throughout their height both from the
wall and from each other. At each corner of the transept the thickening
of the wall over the clearstorey arcade is carried by a shaft which
rises from the bench-table or the ground.

The roof is entirely modern, and the shields on its corbels bear the
arms of the chief promoters of the last restoration.
